The Taxation of Distributions 

from Retirement Savings Plans

April 2004

Previously Published as CBO Technical Paper 2004-06
Preface

This paper investigates how distributions from employment-based and individual

retirement plans are made and taxed, focusing on a snapshot from 1997. In that year, only

about half of distributions fit the usual stereotype of a pension, that is, a regular payment

received after retirement. The rest were rolled over to other retirement accounts or

withdrawn for reasons other than retirement. Of distributions that were not rolled over,

around two-thirds came from defined benefit plans. Just over 10 percent of distributions

were from funds contributed on an after-tax basis and therefore not subject to tax upon

withdrawal. Recipients of government pensions relied more heavily on the pensions for

income than any other group, probably because many did not participate in the Social

Security system.

Paul Burnham of the Congressional Budget Office’s Tax Analysis Division wrote this

paper. It was originally published as CBO Technical Paper 2004-06.

another or paid to the government as taxes are included in gross distributions but are not considered disposable.

Introduction

This paper is a companion to the Congressional Budget Office (CBO) Paper titled

“Utilization of Tax Incentives For Retirement Saving.” That document focused on the front

end of the tax incentives; i.e. when the contributions are made to a retirement savings plan.

This document investigates the back end; i.e., when the savings are withdrawn by or

distributed to participants. Specifically, the paper addresses how retirement plan

distributions are made and taxed, how much distributions from different types of plans

contribute to the disposable and taxable income of recipients, and how important retirement

plan distributions are as a source of income to those recipients.

This study utilizes a database constructed with tax return information from Forms 1040 and

1099-R and pension plan information from Form 5500. With that database it is possible to

estimate how gross, taxable, and disposable retirement plan distributions break down by

form of distribution (i.e., partial or total) and type of distribution (e.g., regular, early,

disability, and rollover).

1

 It also facilitates a summary of the prevalence and characteristics

of a variety of plan types (e.g., individual retirement account, defined benefit, 401(k), and

other defined contribution). The database also includes other sources of income, such as

Social Security benefits, wages, interest, and dividends to permit an analysis of the relative

importance of retirement plan distributions to different age groups.
2. Distributions reported on the “pensions and annuities” line of Form 1040 may come from a plan that is technically

neither a pension nor an annuity. Nevertheless, such distributions are referred to in this paper as “pension” distributions

to conveniently distinguish them from IRA distributions, which are reported on a separate line. The term “retirement

plan distributions” encompasses both lines.

2

How Retirement Plan Distributions Are Made and Taxed

Retirement plans are designed to provide people with a stable source of income after they

retire, so it is natural to think of pension and annuity payments in that way. The

stereotypical retirement plan distribution is a series of equal or indexed annuity payments

that extend over the life of the retiree (and, often, that of a secondary beneficiary). In 1997,

however, less than half of gross pension distributions reported on Form 1099-R (or implied

by Form 1040) conformed to that general pattern.2 Some payments differed in “form”

because they were not periodic. Others differed in “type” because they were made for

purposes other than retirement at the normal age. 

Form of Distribution

Payments that conform to the stereotypical retirement plan distribution are classified as

“partial distributions” on Form 1099-R. Partial distributions need not, however, be in the

form of equal or indexed annuity payments. Some employers permit withdrawals from a

defined contribution (DC) plan to be made over a fixed period of time, or in equal amounts

until funds are exhausted. Discretionary withdrawals from individual retirement accounts

(IRAs) of amounts less than the account balance are also classified as “partial distributions.”

For purposes of this paper, however, all partial distributions are deemed to conform to the

stereotypical pattern, at least in terms of form.
3. Section 1035 exchanges are separately identified on Form 1099-R but are the equivalent of a rollover for nonqualified

annuities; i.e., those that are purchased by individuals directly from insurance companies.

The alternative to partial distributions—total distributions—are more commonly known as

“lump-sum distributions.” Most such distributions are made upon changing employers or

upon retirement in lieu of an annuity. In 1997, 79 percent of lump-sum pension distributions

were rolled over to an IRA, to another qualified plan, or to another annuity and thus could

not affect the recipient’s current standard of living.3 A much smaller percentage (less than

10 percent) of partial distributions were also rolled over. Research using similar data from

1995 indicated that large lump sum distributions were more likely to be rolled over than

were small ones.4

 Furthermore, small distributions were much more common than large

ones. Hence, although most of the funds distributed as lump sums were rolled over, most

recipients of lump sum distributions did not roll them over. 

In 1997, approximately 70 percent of all pension distributions were classified as partial (see

Table 1). Of those, 70 percent were made pursuant to normal retirement (hence, 49 percent

of all distributions—less than half—conformed to the stereotypical pattern). Of pension

distributions that were not rolled over, however—in other words, those leaving the

retirement savings system and thus becoming available for consumption—approximately

70 percent conformed to the stereotypical pattern. IRA distributions are somewhat less

likely to conform to that pattern than are pension distributions—only 45 percent of all

distributions and 59 percent of nonrollover distributions.
4

Type of Distribution

Payments that conform to the stereotypical retirement plan distribution are classified as

“regular distributions” on Form 1099-R. Regular distributions are those made pursuant to

retirement at or above the normal retirement age. Several other types of distribution are

identified on Form 1099-R, including disability benefits, deathbenefits, “early” distributions

(that is, those made prior to age 591⁄2 for reasons other than the disability or death of the

primary beneficiary), and rollovers. To encourage people to hold their savings until

retirement, certain early distributions are subject to a 10 percent penalty tax. Other early

distributions, however, are made for reasons that Congress has chosen not to penalize. Form

1099-R distinguishes between early distributions that are subject to penalty tax and those

that are not. The same set of type codes is used for IRAs and pensions.

Regular distributions constituted just over half of both pension and IRA distributions in

1997 (see Figures 1 and 2). In spite of the recent shift away from defined benefit plans, such

plans remain the source of the vast majority of regular retirement plan distributions.

Government plans accounted for the biggest share—43 percent, but private defined benefit

plans also claimed a 24 percent share (see Table 2). Only 9 percent of taxable regular

distributions came directly from defined contribution plans, although another 16 percent

came from IRAs (which receive most of their funds from rollovers from defined contribution

plans). 

Disability benefits are paid to retirees who have not yet reached the normal retirement age,

but cannot work because of a disabling physical or mental condition. Although disability

benefits are also paid by the Social Security Administration, only those paid by
5. Department of Labor, Bureau of Labor Statistics (BLS), National Compensation Survey: Employee Benefits in Private

Industry in the United States, 2000, p. 58; BLS, Employee Benefits in State and Local Governments in 1998, pp. 98.

employment-based plans and IRAs are covered here. In 1997, they constituted

approximately 2 percent of pension distributions and less than 1 percent of IRA

distributions. Very few such distributions were made in lump sums.

Disability benefits are very common among defined benefit plans, extending to 69 percent

of participants in the private sector (in 2000), 97 percent of participants in state and local

governments (in 1998), and all federal employees.5 However, plans may make eligibility

for such benefits contingent on service of as much as 10 years for state and local employees

and 15 years for private-sector employees. In 1997, over 80 percent of disability payments

came from defined benefit plans and nearly half of those came from a single plan—the Civil

Service Retirement System (CSRS), to which most civilian retirees of the federal

government belong.

Defined-contribution plans and IRAs do not offer explicit disability benefits. Disabled

individuals under age 591⁄2 may, however, draw on their account balances without incurring

penalty taxes. Occasionally, such withdrawals from IRAs and employer-funded DC plans

are designated as disability payments on Form 1099-R, but withdrawals from 401(k) plans

are almost never so designated.

Death benefits are paid to survivors of workers or retirees pursuant to provisions of a plan.

Approximately 4 percent of distributions from both pensions and IRAs were classified as
6

death benefits in 1997. Nearly one-quarter of death benefits paid by pension plans were

made as lump sums, as were nearly half of such benefits paid by IRAs.

Death benefits are almost universally provided by defined-benefitplans;they typically equal

the amount that the survivor would have received had the employee retired instead of died

at that time. In 1997, nearly 30 percent of death benefits were paid by the CSRS, with

another 20 percent coming from other employment-based defined benefit plans.

Nonqualified annuities—which frequently have a life insurance component—made up the

next largest share at 27 percent.

Defined-contribution plans and most IRAs do not offer explicit death benefits. Upon the

death of a participant, the balance in the account is transferred to his or her designated

beneficiaries, who can withdraw it, regardless of their ages, without being subject to the

penalty tax on early withdrawals. Such distributions are rarely designated as death benefits

on Form 1099-R. Occasionally, however, IRAs are used to purchase annuities that contain

explicit death benefits. Payments from such plans probably explain most of the 18 percent

of death benefits coming from IRAs.

Early distributions not subject to penalty tax are typically, but not always, payments made

as part of a fixed annuity to people who retire prior to age 591⁄2 or a plan’s normal retirement

age, whichever is earlier. They constituted 4 percent of pension distributions and 2 percent

of IRA distributions in 1997. 
7

Fixed annuity payments are characteristic of defined benefit plans and most such plans

(other than cash balance plans) have a provision allowing retirement prior to age 591⁄2.

Hence, such plans accounted for nearly three-quarters of early distributions not subject to

penalty tax. The remaining quarter were generated by defined contribution plans and IRAs.

Some of those may represent annuity payments—a minority of DC plans allow distributions

to be made in that form and any IRA can be converted to an annuity prior to distribution.

A significant share of early distributions not subject to penalty tax reported by DC plans and

IRAs, however, probably represents payments to survivors or disabled retirees—categories

that are tabulated elsewhere for defined benefit plans. Some may also have been used to

cover medical expenses in excess of 7.5 percent of AGI, an exception to the penalty tax

allowed for the first time in 1997. Exceptions for higher education expenses and first-time

home purchases, however, were not available until 1998.

Early distributions subject to penalty tax constituted 5 percent of pension distributions and

15 percent of IRA distributions in 1997. In contrast to early distributions not subject to

penalty tax, those subject to penalty tax came overwhelmingly from defined contribution

plans. Such plans—particularly 401(k)s—often allow early withdrawals (usually for

hardship reasons only) or loans. Penalty taxes apply when early withdrawals are made for

reasons other than hardship, when the hardship is not one that qualifies for an statutory

exemption from the penalty tax, or when a loan is not repaid on schedule. Withdrawals can

be made from IRAs at any time (although loans are not permitted), and penalty taxes apply

under largely the same conditions as 401(k)s. Together, IRAs and 401(k) plans generated

60 percent of distributions subject to penalty tax in 1997. 
6. There is evidence to suggest that many of the noncontributory plans generating rollovers may, in fact, be 401(k)s but

are not identified as such on Form 5500.

8

Other DC plans are less likely to allow early withdrawals or loans, and defined benefit plans

allow neither. Most distributions subject to penalty tax from such plans are made in lump

sums—possibly upon termination of a plan—and are not rolled over to an IRA or another

qualified plan. Such plans accounted for another 13 percent of distributions subject to

penalty tax. The remaining withdrawals subject to penalty tax were mostly from

nonqualified annuities, which have to allow such withdrawals but frequently impose

penalties in addition to the tax.

Rollovers occur when an employer or IRA administrator is instructed to transfer a

distribution directly to an IRA or qualified plan. Most rollovers are lump-sum distributions,

a form of distribution characteristic of DC plans and IRAs: 73 percent of rollovers came

from such plans in 1997. The majority of qualified plan rollovers were from 401(k) plans

(i.e., those that allow pre-tax contributions by participants) to IRAs, although employerfunded DC plans also generated a substantial amount of rollovers.6

 Rollovers from one IRA

to another were also significant.

The rollover designation on Form 1099-R does not identify all funds actually rolled over.

Some regular and early distributions are paid to the recipients, who then deposit them in an

IRA. Because the payer does not know how the recipient will dispose of the funds, it cannot

identify them as rollovers on the 1099-R. Section 1035 exchanges, in which funds from one

nonqualified annuity are used to purchase another, are identified separately on Form 1099-

R. Such exchanges, however, are functionally rollovers and are counted as such in all of the

tables in this paper.
7. Note that basis does not include any earnings that accumulate in the plan as a result of after-tax contributions—only

the original value of the contributions themselves.

9

Several minor types of distribution are identified on Form 1099-R, and sometimes preparers

do not indicate the type. The most common other type is the Railroad Retirement

distribution in excess of the Social Security equivalent. Every other type of plan also has

some “other and unknown” distributions, but private defined benefit plans and 401(k)s had

the most in 1997.

The Taxation of Distributions

All types of distributions except rollovers were potentially taxable in 1997. Furthermore,

any given nonrollover distribution could be either fully or partially taxable. The reason that

not all nonrollover distributions are fully taxable is that a portion sometimes represents the

recovery of amounts contributed to the plan from after-tax wages, an amount commonly

known as “basis.” Because it was taxed at the time of contribution, basis is exempt from tax

upon withdrawal to avoid taxing it a second time.7 In general, basis is recovered

proportionally over the life-expectancy of the beneficiary. If it is fully recovered during the

life of the beneficiary, then all subsequent distributions are fully taxable. If unrecovered

basis remains upon the death of the beneficiary, it may all be recovered on the decedent’s

final tax return.

Basis recovery is most important for nonqualified annuities. All contributions to such

annuities are after-tax and thus create basis to be recovered upon distribution. Most

contributions to IRAs and qualified plans are pre-tax, and thus create no basis.

Private Pension Plan Bulletin, no. 1 0 (Wint er 2001 ), Table E4 , availa ble a t

www.dol.gov/ebsa/programs/opr/oprpubs.htm.

10

Nevertheless, significant amounts of basis have accumulated in IRAs and qualified plans

through exceptions such as the following:

• Limits on IRA deductibility since 1987 have resulted in the creation of

“nondeductible IRAs,” the contributions to which are after-tax.

• Certain defined benefit (DB) plans, in contrast to the usual pattern, require after-tax

contributions by employees. 

• Many after-tax contributions to “thrift” plans—a precursor to 401(k)s—were rolled

over into 401(k)s after pre-tax contributions were authorized.

Very few thrift plans remain in existence, and Roth IRAs—instituted in 1998—have

virtually eliminated the nondeductible IRA. Therefore, little new basis is being created and

its recovery will be less of a factor in the future.

Overall, approximately 63 percent of pension distributions and 67 percent of IRA

distributions were taxable in 1997 (see Table 3). Of the nontaxable portion, basis recovery

accounted for approximately 21 percent for pensions and 26 percent for IRAs. Most other

nontaxable distributions were rollovers.

Disposable and Taxable Pension Distributions by Type of

Plan

In 1977, almost 85 percent of private-sector workers who were covered by a retirement plan

participated in a DB plan; 20 years later, fewer than half did.8 That shift has already

affected the tax system in that it has changed the way in which tax incentives to contribute
11

to such plans are used. Published data are generally adequate for measuring the shift away

from traditional DB plans and towards 401(k)-type plans with regard to contributions made

and assets held. Ultimately, however, it is the distributions and withdrawals that affect

retirees’ well being, and published data are not adequate to determine how much each type

of plan contributes to the disposable income of retirees and other pension beneficiaries.

Furthermore, one cannot use published data to estimate the amount of taxable income

generated by each type of plan. Data from Forms 1099-R, augmented by information from

Forms 5500, however, provide sufficient information to generate such a breakdown.

Why Does the Type of Plan Matter?

In many senses, the type of plan from which a distribution or withdrawal is made is not

important. The tax system does not care whether a distribution came from a DB or a DC

plan because the law treats them the same way. Furthermore, funds from a DC plan can be

spent by the recipient in exactly the same way as funds from a DB plan. The key difference

between them is the degree of stability they typically offer. A person in a DB plan who

retires can count on a certain nominal level of benefits for the rest of his or her life (and

usually that of a spouse, albeit at a lower level). Only if the plan were to become insolvent

and be taken over by the Pension Benefit Guaranty Corporation (PBGC) would there be any

risk of benefits being reduced, and then only if benefits exceeded a certain maximum

($3,579.55 per month for those retiring at age 65 in a plan terminating in 2002). Those in

an indexed plan receive increasing amounts of nominal benefits over time and have the

additional security of protection against the cost of inflation.
12

A person with an IRA or in a DC plan who retires has a great deal of flexibility with respect

to how he or she will receive benefits. That flexibility allows retirees to establish (among

other things) a level of stability comparable to that in a DB plan by purchasing an annuity,

make large withdrawals in cases of emergency (or even just to enjoy life while still in good

health), or continue to accumulate assets in hopes of increasing either future distributions

or bequests to heirs. The last option presents the possibility that assets could decline in

value rather than increase, which would lead to lower future distributions. Thus, the

flexibility of DC plans and IRAs makes it difficult to predict the level of both taxable and

disposable distributions. Breaking down distributions by type of plan, therefore, provides

a sense of both how stable those payments are and how much flexibility their recipients

have.

Defined Benefit Plans and Nonqualified Annuities

In 1997, 57 percent of retirement plan distributions reported on Forms 1099-R came from

defined benefit plans. At first glance, that result might seem consistent with the share of

retirement plan assets held in DB accounts—approximately 55 percent that year. In fact,

however, DB plans accounted for a significantly higher share of both taxable and disposable

retirement plan distributions—around 70 percent in both cases (see Figure 3). The

percentage of assets in DB plans is lower than the percentage of distributions because assets

in DB plans are distributed among age groups very differently than are assets in DC plans.

A much higher percentage of DC plan assets is held by those not yet of retirement age. As

workers participating in DC plans retire, however, larger and larger percentages of

distributions will come from DC plans and IRAs.
13

When it comes to the stereotypical pension distribution discussed above (that is, an annuity

payment to a retiree), DB plans generate an even higher share—over three-quarters. DB

plans also generate a disproportionate share of death benefits, disability benefits, and other

early distributions that are not subject to penalty tax. 

Nearly one-quarter of distributions by DB plans are made by just two plans—the Military

Service Retirement System (MSRS) and the Civil Service Retirement System. Another

quarter are made by other government plans. The other half come from private employmentbased plans and nonqualified annuities. How can public sector retirees account for half the

distributions from DB plans when employment levels in the public sector have never

approached those in the private sector? One factor is that virtually all government

jurisdictions offer a DB plan; many private sector employers do not. Furthermore, the

government plans have certain characteristics that increase their share of DB plan

distributions. The most important are the following:

• All federal plans and most state and local plans use the highest three years of

compensation when determining post-retirement benefit levels. Most private plans,

in contrast, use the highest five years. Including those extra two years necessarily

reduces the benefit from a private plan even if it is otherwise identical to a public

plan.

• Public plans typically allow retirement with full benefits at a younger age than do

private plans. Given identical life expectancies for public and private retirees, that

feature would result in a percentage of retirees from the public sector that is higher

than the corresponding percentage of employees had ever been.
14

• Unlike public plans, some private plans do not provide disability benefits. The

concentration of disability benefits in public sector plans further increases their

share of total distributions.

• Benefits from federal plans and about half of state and local plans are indexed for

inflation. Benefits from private plans, in contrast, are rarely indexed. Hence, the

share of benefits received by government retirees who retired in a given year will

increase over time relative to that of private sector retirees who retired in that same

year.

• Benefits from the CSRS and certain state and local plans are designed to replace

Social Security benefits, not just to supplement them. Thus, the amounts reported

on Form 1099-R are much higher than those from private-sector plans that, when

combined with Social Security, provide the same level of retirement income.

• Private sector plans are more likely to allow distributions to be taken in a lump sum.

That characteristic has little effect of the shares of gross distributions, but tends to

reduce the share of taxable and disposable distributions because many of those lump

sums are rolled over to IRAs. Rolled over funds are not counted as taxable or

disposable until withdrawn from the IRA.

Since 1984, all new federal civilian employees have been enrolled in the Federal Employees

Retirement System (FERS) instead of CSRS. That plan is designed to supplement Social

Security rather than replace it, so its benefits are lower than those of CSRS. Furthermore,

it is not fully indexed for inflation. Thus, as the number of federal retirees on FERS grows

and the number on CSRS shrinks, federal civilian benefits could decline as a share of all DB

distributions.
9. The 1996-97 figure was estimated using a weighted average of figures from Department of Labor, Bureau of Labor

Statistics (BLS), Employee Benefits in Small Private Establishments, 1996, p. 72 and Employee Benefits in Medium

and Large Private Establishments, 1997, p. 103. The 2000 figure comes from BLS, National Compensation Survey:

Employee Benefits in Private Industry, 2000, p. 58.

15

Another important trend that is not reflected in the 1997 data is the growth of cash balance

plans, a relatively new form of DB plan. That trend will likely reduce the share of taxable

and disposable benefits made by private DB plans. One of the main features of cash balance

plans is their portability. Between 1996-97 and 2000, the percentage of private DB plans

allowing lump-sum distributions nearly doubled (from 22 percent to 43 percent)—a direct

result of the growth in cash balance plans.9 Many of those lump-sum distributions will be

rolled over to IRAs or 401(k)s and will never be counted as taxable or disposable

distributions from DB plans.

Defined Contribution Plans and Individual Retirement Accounts 

Of the 43 percent of gross distributions not attributable to DB plans in 1997, over 60 percent

were from defined contribution plans. The remainder were from IRAs. Those two sources

of distributions, however, accounted for only 30 percent of taxable and disposable

distributions. The split between DC plans and IRAs, however, was almost reversed; it was

IRAs that accounted for nearly 60 percent of taxable and disposable distributions. The

reason for that difference is that a majority of distributions from DC plans are rolled over

to IRAs or other DC plans. Hence, they are neither taxable nor disposable. Some IRA

distributions are rolled over to other IRAs also, but the percentage of gross distributions

rolled over is much less than for DC plans. Furthermore, not all DC plans follow the same

pattern in terms of types of distributions.
16

Of defined contribution plans, 403(b) plans come the closest to conforming to the

stereotypical pattern (see Table 4). Such plans have been used by nonprofit organizations

since 1958 (and by public schools since 1961) to allow employees to make pre-tax

contributions to their retirement plan. Although that feature resembles a 401(k), other

features are more restrictive. For example, employees exercise much less control over their

403(b) investments that do typical 401(k) participants. Furthermore, lump-sum distributions

are not permitted under such plans, nor, prior to the Economic Growth and Tax Reduction

Reconciliation Act of 2001 (EGTRRA), were rollovers to qualified plans. Approximately

15 percent of distributions in 1997 were rolled over to IRAs, however. Overall, more than

three-quarters of 403(b) distributions were taxable. Only 10 percent of taxable distributions

were made for reasons other than normal retirement, and distributions subject to penalty tax

were very rare.

401(k) plans were created in 1978 to allow employees of participating businesses to make

pre-tax contributions to their retirement plan. Typically, 401(k) plans offer a great deal of

flexibility in terms of how much to contribute, how to invest those contributions, and when

to withdraw them. Of all the different types of retirement plan, the 401(k) plan’s

distribution pattern diverges most significantly from the stereotypical pattern. Two-thirds

of 401(k) distributions in 1997 were made as lump sums. More than 70 percent (including

some partial distributions) were rolled over to IRAs, and another 8 percent were nontaxable

for other reasons. Of taxable distributions, less than half were made pursuant to normal

retirement and over 40 percent were subject to penalty tax.
17

Other defined contribution plans do not allow pre-tax contributions by employees. Their

distribution patterns are more similar to 401(k)s than to 403(b)s, but they do not diverge

from the stereotypical pattern as extremely. Over half of such distributions in 1997 were

made as lump sums and a similar percentage were rolled over to IRAs or other qualified

plans. Overall, only 38 percent of distributions from such plans were taxable. Of those that

were taxable, less than half were made pursuant to regular retirement and 28 percent were

subject to penalty tax.

Individual retirement accounts were authorized in 1974 and have undergone many changes

since then to allow most taxpayers to make pre-tax payments to a retirement plan without

going through an employer’s plan. Because IRAs could not be rolled over to qualified plans

prior to EGTRRA, lump sum distributions and rollovers were not as common as in defined

contribution plans. Only 30 percent of IRA distributions were made in the form of a lump

sum and one-quarter of IRA distributions (including some partial distributions) were rolled

over to another IRA. Overall, two-thirds of IRA distributions were taxable. Of taxable

distributions, approximately 30 percent were classified as something other than “regular”

for one reason or another, and 60 percent of those were subject to penalty tax.

Roth IRAs were not introduced until 1998, so they are not reflected in the 1997 data.

Withdrawals from Roth IRAs are generally not taxable (in stark contrast with every other

type of retirement plan) and thus bear close watching in the future. Approximately half of

IRA contributions since 1998 have been to Roth IRAs, but Roth’s have not yet built up

enough assets to generate any significant withdrawals.
10. By income, I mean cash flow which can fund consumption. 

18

Retirement Plan Distributions as a Source of Income

Pension plans and IRAs are designed to defer consumption from one’s working years until

after retirement. Hence, it is useful to investigate the role distributions from such

plans—which are intended to fund the deferred consumption—play for taxpayers of

different age groups. We can also investigate which types of distributions are most

important to their recipients.

Differences by Age Group

As taxpayers approach and then pass normal retirement age, the sources of their income

change.10 The importance of retirement plan distributions grows relative to earnings, but so

does the importance of other sources of income such as Social Security and investment

earnings outside of retirement accounts. Retirement plan distributions to older recipients

are also more likely to be classified as “regular,” and those regular distributions are more

likely to come from private plans than are regular distributions to younger recipients.

Sources of Income. In 1997, retirement savings distributions accounted for only 2 percent

of the income of taxpayers under age 60 (see Figure 4). As taxpayers age, the importance

of income from retirement savings rapidly increases in importance. For taxpayers between

the ages of 60 and 64, such distributions made up 18 percent of the income; for taxpayers

age 65 and above, they accounted for just over one-quarter of total income. There was little

difference, however, between those between the ages of 65 and 69 and those ages 70 and

above. Note that these results apply only to taxpayers; they cannot be extrapolated to cover
19

people who did not file tax returns. Such people tend to have very different income patterns

than filers, typically relying less on income from retirement savings and more on Social

Security.

Just as income from retirement savings increases in importance with age, earned income

declines in relative importance. For taxpayers under age 60, earnings provided nearly 90

percent of total income. Between the ages of 60 and 64, however, the share drops to just

over half, then to around 30 percent between ages 65 and 69, and to below 10 percent for

age 70 and above.

The percentage of income coming from investments outside ofretirement accounts increases

with age, growing from 9 percent for taxpayers under 60 to 47 percent for taxpayers age 70

and above. That source of income, rather than Social Security or retirement plan

distributions, offsets the reduced importance of earnings for taxpayers age 70 and over.

Social Security accounted for hardly any of the income of taxpayers under 60 and for only

6 percent of the income of taxpayers between 60 and 64—the group that includes those

taking advantage of Social Security’s early retirement option. Above the normal Social

Security retirement age of 65, the percentage of income coming from Social Security

increased to 14 percent, and reached almost 18 percent for taxpayers age 70 and above. 

Types of Distribution. Over 90 percent of all retirement plan distributions to taxpayers age

60 and over are regular distributions, with death and disability benefits accounting for most

of the rest (see Figure 5). In contrast, over half of distributions received in 1997 by
20

taxpayers under 60 were early distributions, and nearly two-thirds of those distributions

were subject to penalty tax. Death and disability benefits also accounted for a slightly

higher percentage of distributions in the under 60 age group than in the 60 and over group.

Sources of Regular Distributions. Nearly three-quarters of regular distributions in 1997

to taxpayers under 60 were for military retirement (40 percent) or from other government

plans (32 percent; see Figure 6). Distributions from private defined benefit plans accounted

for somewhat more than half of the rest. Only 12 percent of regular distributions to

taxpayers in that age group were from IRAs or defined contribution plans.

Regular distributions to taxpayers age 60 and above were more balanced. Nearly half came

from government plans (less than 20 percent of which was military), with another fourth

coming from private defined benefit plans. Of the remainder, distributions from IRAs were

nearly twice as large as those from DC plans.

The Importance of Each Type of Distribution to Its Recipients

The different types of distributions from retirement plans provided varying shares of

recipient’s income with no single type accounting for as much as one-third of beneficiaries’

total income. Regular distributions from government plans were the most important to their

recipients in 1997, accounting for 31 percent of their incomes (see Figure 7). That result

reflects the fact that many such retirees do not participate in the Social Security system and

rely on their government pension to offset that. 
21

Of recipients of regular distributions from private plans, those receiving distributions from

defined benefit plans were more dependent on those distributions than were recipients of

distributions from defined contribution plans. On average, distributions from defined

benefit plans accounted for 23 percent of a recipient’s total income, while distributions from

a defined contribution plan made up 18 percent of a recipient’s income. The importance of

IRA distributions to their recipients was similar to that of defined contribution plans,

averaging 17 percent of total income.

Of recipients of early distributions, the most dependent (at 24 percent of total income) were

recipients of those that are not subject to penalty tax. The least dependent group (at just

over 10 percent of total income) were recipients of early distributions from employmentbased plans that are subject to the penalty tax. Recipients of early IRA distributions subject

to penalty tax received approximately 15 percent of their income from that source. If

exemptions from the penalty tax are intended to protect those who truly need the funds,

those exemptions appear to be generally well targeted.

Dependence on death and disability benefits varied somewhat by age. For recipients under

age 60, such benefits constituted only 17 percent of total income. For older recipients,

however, death and disability benefits accounted for over one-quarter of total income.

Appendix A:

Compilation of the Database

No published source of data on pension distributions breaks down either taxable

distributions or disposable distributions by type of plan. Microdata from Forms 1040, 1099-

R, and 5500 however, contain most of the information necessary to construct a database that

would accomplish that task. Form 1099-R reports amounts and characteristics of pension

and IRA distributions. Form 5500 reports the characteristics and financial status of

qualified retirement plans. Creating the database consisted of four distinct steps:

1. Matching amounts of retirement plan distributions on Forms 1099-R with amounts

reported on a federal tax return and reconciling the differences,

2. Distinguishing between government plans (which were virtually all DB plans), and

private plans (which could be either DB or DC),

3. Determining whether private plans were DB or DC plans, and

4. Deleting records for which a plan type could not be identified and reweighting the

remaining records to represent the entire population.

Review of Published Data on Pension Distributions

Before evaluating the existing data sources, it is helpful to have working definitions of the

two variables of interest: taxable distributions and nonrollover distributions. Simple

definitions used in this paper are as follows:

(1) Gross distributions

less (2) Rollovers and Exchanges

less (3) Basis Recovery
34

less (4) Otherwise taxable distributions received by nonfilers

equals (5) Taxable distributions

(1) Gross distributions

less (2) Rollovers and Exchanges

less (6) Otherwise disposable distributions received by nonfilers

equals (7) Nonrollover distributions

The Statistics of Income Division (SOI) of the Internal Revenue Service publishes only two

figures per year for pensions and annuities: gross distributions of filers (line 1 minus line

4) and taxable distributions (line 5). It does not separately identify rollovers and basis

recovery. Therefore, published SOI data cannot be used to estimate disposable distributions

(line 7) even in the aggregate. 

The Employee Benefits Security Administration (EBSA) publishes data from Form 5500

that break down gross distributions (line 1) made from private plans by type of plan. Similar

figures are available for government plans from the Census Bureau (for state and local DB

plans), the Office of Personnel Management (for federal civilian DB plans), and the Defense

Finance and Accounting Service (for the military plan). None of those sources, however,

contains any information on rollovers, basis recovery, or tax rates, so they are useful

primarily as control totals for gross distributions. Furthermore, distributions from 403(b)

plans are not covered by any of those sources.
35

Surveys such as the Current Population Survey (CPS), the Survey of Consumer Finances

(SCF), and the Survey of Income and Program Participation (SIPP) ask respondents how

much they receive from their retirement plans. The intent is to pick up pre-tax amounts of

all distributions except rollovers and exchanges. Only the SIPP, however, makes any

attempt to identify distributions specifically from 401(k) plans—approximately $5 billion

in 1995. Other types of DC plans, however, cannot be identified on the SIPP. 

In the absence of adequate published data, it was necessary to use microdata from Forms

1040, 1099-R, and 5500 to construct a database that would allow breakdowns by type of

plan. SOI generates a sample of Forms 1040 that is considered to be of exceptionally high

quality because of the legal obligations surrounding the filing of tax returns, the large

sample size (approximately 100,000 returns), and the extensive consistency checks

performed by the IRS. 

SOI also provides a file containing certain information returns, including Forms 1099-R, that

were associated with the tax returns in the sample. Form 1099-R, prepared annually by

pension and IRA administrators and sent to all recipients of distributions, reports their

respective gross and taxable distributions, identifies whether they were total or partial

distributions, and classifies them by type. Individuals receive one Form 1099-R for each

pension or IRA from which they receive a distribution. The 1099-Rs are subject to the same

legal obligations as the 1040s but have not undergone the same level of consistency checks

that the 1040 data have. CBO devised its own protocol of data-cleaning procedures to

render the file of 1099-Rs for tax year 1997 consistent with the data from the 1040 in the

same year.
36

In some cases, the payer ID on Form 1099-R is sufficient to identify the type of plan from

which a distribution was made. In other cases, however, the type of plan could only be

identified by referring to the Form 5500 submitted by the payer to the EBSA. That form

provides the government with extensive information on the financial status of the plan, and

contains codes identifying the type of plan. CBO obtained the entire file of Forms 5500 for

1997 from EBSA.

Reconciling Distribution Amounts on Forms 1099-R With Those on Form 1040

The original file of 1099-Rs contained 71,233 forms. Of those, 776 were eliminated because

they were for years other than 1997. Of the remainder, 698 were coded as amended or

“amended original” returns. CBO developed a set of rules to determine when amended

returns should be used in place of original returns. In general, amended returns were

retained and original returns that had been amended were deleted. As a result of applying

those rules, 444 records were deleted.

All 1099-Rs must indicate whether the distribution is from a pension or from an IRA. That

classification was used to compare the gross and taxable amounts for pensions and IRA

distributions on all of a taxpayer’s 1099-Rs with the corresponding fields on his or her 1040.

If all four values from the combined 1099-Rs were within $10 of the corresponding fields

on the 1040, the records were deemed to be a match. Some nonmatches had obvious causes,

such as amounts from an extra 1099-R not being included in the total reported on the 1040,

or amounts being reported as pension distributions on one form but IRA distributions on the

other. Several remedies were applied to correct those problems and achieve matches (see

Table A-1). 
11. Forms 5498 are prepared annually by administrators of IRAs and sent to the accounts’ owners to report their

contributions, rollovers, and end-of-year balances. The processing of Forms 5498 is described in Appendix A of the

CBO Paper titled “Utilization of Tax Incentives for Retirement Saving.” Amended 5498s were handled in a manner

similar to that of 1099-Rs, but no fields on Form 5498 correspond precisely to fields on Form 1040, so no reconciliation

could be made.

37

No remedies were allowed to change the value of taxable pensions or taxable IRA

distributions on Form 1040. Gross pension and gross IRA distributions on Form 1040 as

well as all information on Forms 1099-R, however, were subject to modification to achieve

matches. 

One common problem was that amounts classified as pensions on Form 1099-R were

reported on the IRA distributions line of Form 1040 or vice versa. Because taxable

distributions on Form 1040 were always deemed to be correct, the codes on Form 1099-R

were changed in 5,854 cases to achieve reconciliation. 

A less common problem was reporting gross amounts from Form 1099-R as taxable on Form

1040. In 643 cases, reconciliation was achieved by replacing the taxable amount on the

1099-R with the gross distribution. In 195 other cases, replacing the gross amount with the

taxable amount achieved reconciliation.

Other remedies utilized information on rollovers from Form 5498.11 Payers who send out

1099-Rs may not know whether a distribution is going to be rolled over into an IRA or

qualified plan and therefore be nontaxable. In such cases, they simply report the taxable

amount to be the same as the gross amount and indicate in a specific box that the taxable

amount has not been determined. Taxpayers who roll their distributions over properly report

a lower amount of taxable distributions on Form 1040 than indicated on the Form 1099-R.
38

If the rollover was made to an IRA, it should be identified on Form 5498. Rollover amounts

from that form were used as follows:

1. When the taxable amounts from the 1099-Rs exceeded the taxable amounts on Form

1040, rollover amounts from Form 5498 were subtracted from taxable amounts on the

1099-Rs to see if they explained the discrepancy. 

2. When the gross amounts from the 1099-Rs exceeded the gross amounts on Form 1040

while the taxable amounts matched, that was taken as a sign that perhaps the taxpayer

did not accurately report the gross distribution on Form 1040. Rollover amounts from

Form 5498 were therefore added to the gross amounts on Form 1040. This was the

only remedy in which an amount on Form 1040 was changed, but it did not affect tax

liability. 

3. Any remaining rollovers from Form 5498 not accounted for on the 1099-Rs were

counted as “inferred rollovers” up to the unexplained difference between the gross

and taxable amounts. 

4. Any other difference between gross and taxable amounts was attributed to basis

recovery; i.e. distributions that are deemed to come out of after-tax contributions and

which are therefore nontaxable. Basis recovery was not otherwise identified on Form

1099-R.

The remaining unreconciled cases fell into two categories: returns in which an amount on

Form 1040 exceeded the corresponding amounts on all of a taxpayer’s Forms 1099-R, and

returns in which an amount on Form 1040 fell short of the corresponding amounts on Forms

1099-R. In the former case, which occurred 3,257 times, dummy 1099-Rs were created
39

containing the missing amounts. In the latter case, an attempt was made to identify a

combination of 1099-Rs that matched the total on the 1040. When such a combination was

found, the superfluous 1099-Rs (9,256 in all) were deleted. When no combination of 1099-

Rs matched the 1040, the amounts on all of the taxpayer’s 1099-Rs were scaled to hit the

proper total. Taxable distributions on 6,698 1099-Rs were modified in this manner, as were

gross distributions on 3,624 1099-Rs.

Identifying Payments From Government Plans

Payments from government plans on Form 1099-R are relatively easy to identify using the

payer name. Five different types of such payments were identified:

1. Federal military retirement benefits,

2. Federal civilian retirement benefits,

3. Railroad Retirement benefits in excess of the Social Security equivalent, 

4. State and local retirement benefits, and

5. 403(b) plan benefits (which are received by employees of nonprofit institutions as

well as public school and university employees).

Federal military retirement benefits. Benefits from the following three payers were

unambiguously identified as being for military retirement: 

• The Defense Finance and Accounting Service, Cleveland Center (2,177 records), 

• The Defense Finance and Accounting Service, Denver Center (306 records), and 

• The U.S. Coast Guard Pay and Personnel Center (39 records).
12. That percentage will increase over time as TSP participants accumulate funds in their accounts and eventually retire.

40

That list is exhaustive of all payers of military retirement benefits. All plans categorized

as “federal military” are defined benefit plans.

Federal civilian retirement benefits. Benefits from the following five payers were

identified as being for federal civilian retirement:

• The Office of Personnel Management (2,454 records),

• The U.S. Department of Agriculture National Finance Center (123 records),

• The Tennessee Valley Authority Retirement System (19 records), 

• The U.S. Public Health Service (17 records), and

• The Administrative Office of the United States Courts (4 records).

There are a few additional payers, but they are very small and are not represented in the

sample. Thus, the identified records were treated as exhaustive of all federal civilian

retirement benefits.

All distributions from federal civilian plans except those made by the USDA National

Finance Center come from DB plans—the vast majority from the Civil Service Retirement

System. The USDA National Finance Center handles the federal Thrift Savings Plan (TSP),

a defined contribution plan that was created in 1986. Distributions from the TSP account

for less than 2 percent of distributions from federal civilian plans.12 They are counted in all

tables with defined contributions plans, not with government plans.
41

Railroad Retirement benefits. The U.S. Railroad Retirement Board was listed as the payer

on 1,218 records. Only those benefits were classified as railroad retirement benefits—a

defined benefit plan. Note that the railroad retirement benefits reported on Form 1099-R

cover only those benefits in excess of the Social Security equivalent. The rest are reported

and taxed as if they were Social Security benefits. Railroad retirement benefits are counted

in all tables with government plans.

State and local retirement benefits. If the sponsoring state or local government was the

payer, these benefits were identified by searching for key words, such as “State,” “County,”

“City,” “Public Employees,” and “Teachers.” Benefits from 242 payers covering 7,058

records were identified as being for state and local retirement. That list is not exhaustive

for two reasons:

1. Some state plans (Nebraska’s, for example) use private contractors to administer their

systems, and payments are made by those contractors. Such payments cannot be

distinguished from payments made by those same contractors on behalf of private

pension funds.

2. Most local government plans are not represented in the sample of 1099-Rs. Many

others are represented by only one 1099-R (that is, one recipient). Of the many

payers represented by only one 1099-R, manually identifying the local governments

among them proved to be too time consuming, so those 1099-Rs were not retained.

State and local retirement benefits identified in the above manner are overwhelmingly

defined benefit plans. In 1997, only a handful (e.g., Nebraska State Employees and West
13. Since 2000, several states have created voluntary defined contribution plans as an alternative to their existing defined

benefit plan.

14. According to 1998 data downloaded from pionline.com, approximately 85 percent of TIAA-CREF assets were in 403(b)

plans. Therefore, a similar percentage of distributions on each record with TIAA-CREF as the payer were assumed to

come from 403(b) plans.

42

Virginia Teachers) were defined contribution plans.13 Four payers covering 12 records were

excluded because they appear to represent payments from 457 plans. Such payments are

properly reported on Form W-2. No reliable method of identifying 457 plan distributions

on Form W-2 could be found, so those plans have been excluded from this analysis. It is

possible, nevertheless, that small amounts of benefits from 457 plans or 403(b) plans—both

defined contribution plans—were reported by payers on the list and are being counted as

state and local retirement benefits. 

403(b) plan benefits. The only 403(b) plan benefits that could be identified with any degree

of confidence were those paid by the Teachers Insurance and Annuity Association

(TIAA—1136 records), the College Retirement Equities Fund (CREF—855 records), and

three other payers (covering four records) whose names included the terms “403B” or “tax

sheltered annuity.”14 The vast majority of 403(b) plans not using TIAA-CREF could not be

identified because their payments were made by money managers who also made payments

on behalf of other types of plans. As with state and local retirement benefits, the records

identified as 403(b) plan benefits were reweighted to represent those not identified.

Identifying Payments From Nongovernmental Plans by Type of Plan

Private plan types were more difficult to identify. Reliable identification was possible for

only about one-quarter of qualified plans and none of the nonqualified plans (which are

generally individual annuities purchased from life insurance companies).
15. These manual links were frequently accomplished using HTML versions of Forms 5500 available through

www.FreeErisa.com.

43

Qualified plans. Qualified private plans are required to file Form 5500, on which they

indicate whether the plan is of the defined benefit or defined contribution type, and also

whether the plan is a 401(k). By linking Forms 5500 to Forms 1099-R based on the payer

ID number on the latter, it was possible to identify the plan type for a portion of benefit

payments. The identification, however, was far from complete for two reasons:

• Most payer IDs belonged not to the employer sponsoring the plan, but to the

insurance or investment company managing the plan. As those companies manage

all different types of plans, their identity is of no help in identifying plan types.

• Many of the payer IDs belonging to the employer sponsoring the plan were used for

payments from all the different plans sponsored by that employer—both DB and DC.

Thus, unless payments from one type of plan overwhelm those made from the other

plans, merely identifying the employer did not help identify the type of plan.

Because of the problem of multiple plans using the same payer ID number, linking back to

the correct 5500 was usually done manually based on the payer name, not the ID number,

for all plans appearing on 30 or more 1099-Rs.15 Sometimes the name on the 1099-R

exactly matched a plan name on a 5500, sometimes it matched a trust name contained within

the 5500, and other times an employer’s plans could be sorted out inferentially by

comparing the number of 1099-Rs associated with each payer ID to the amount of benefits

paid by each plan. 
44

Another method used to identify the plan type was the use of key words. The following

unambiguous key words were used to identify payments in three categories:

• Defined benefit plans: “defined benefit,” and “cash balance,”

• 401(k) plans: “401K,”

• Other defined contribution plans: “money purchase,” and “target benefit.”

Two key words—“profit-sharing” and “ESOP”— used to describe defined contribution

plans may or may not refer to 401(k)s. In those cases, the payer name was checked against

a master list of non-401(k) DC plans generated from the 5500 file for 1997 obtained from

the EBSA. Those found on the master list were classified as employer-funded DC plans and

the rest were classified as 401(k) plans. There is evidence, however, that not all 401(k)

plans identify themselves as such on Form 5500, so the employer-funded DC plan category

may include a number of 401(k) plans.

Applying those methods yielded the following results:

• Defined benefit plans: 773 payers (including the Pension Benefit Guaranty

Corporation) covering 4,961 1099-Rs,

• 401(k) plans: 549 payers covering 2,785 records, and

• Employer-funded defined contribution plans: 221 payers covering 1,011 records

Payments from life insurance companies. Form 5500 contains data on amounts paid to

life insurance companies to purchase annuities for qualified plan beneficiaries but does not
45

contain any data on the amount actually paid by the life insurance companies to the

annuitants. Furthermore, no Forms 5500 are filed for nonqualified commercial annuities,

which are also paid by life insurance companies. Results for this category were therefore

estimated as a residual as explained below in the description of the reweighting scheme.

There was no way to identify which payments were for qualified plans and which were for

nonqualified annuities.

Reweighting Records

All records for which a plan type could not be identified were deleted from the database.

The remaining records were then reweighted to represent the entire population of taxpayers

receiving pension distributions. The adjustment to the weights was based on the ratio of a

control total for the type of plan divided by the amount accounted for on the retained

records.

Published aggregates were located for most types of plans; only the aggregate amount of

distributions from 403(b) plans had to be estimated. All such aggregates, however,

inevitably included payments made to nonfilers who were excluded from the sample of

1099Rs. Thus, they were inappropriate for use as control totals in the reweighting process.

To derive appropriate control totals, the published aggregates had to be adjusted to represent

only payments made to filers. Federal plans were used to estimate a factor by which all of

the different aggregates could be adjusted. The reason for using federal plans was that no

records representing federal retirement benefits were deleted from the database. Thus, any

discrepancy between the control totals for federal retirement and the amounts on the 1099-

Rs could be attributed to nonfilers. In the case of federal retirement benefits, payments to
16. One reason to suspect that recipients of federal pension are more likely to be filers is that CSRS participants do not

receive Social Security benefits for their time in federal service. The compensating pension amount they receive does

not qualify for the same tax relief as normal Social Security benefits, leaving the recipients with higher taxable income.

46

filers constituted 91.5 percent of total payments. In the absence of any other information,

that percentage was used to adjust the published aggregates for all other plan types. To the

extent that recipients of federal pensions are more likely to be filers than recipients of other

types of pensions, that percentage could be on the high side.16

All records for which a plan type could be identified were then tabulated using their original

weights. Then each record’s weight was multiplied by the ratio of the control total to the

tabulated amount (see Table A-2). Because no records representing payments from life

insurance companies were retained, a complete tabulation of all reweighted records does not

add up to the totals obtained by tabulating the full file of 1099-Rs with their original

weights. The difference was deemed to represent payments from life insurance companies.

Appendix B:

Detailed Tabulations by Type of Plan

Once the 1099-Rs were reconciled to the amounts of Form 1040, it was possible to tabulate

gross and taxable pensions and IRA distributions from the 1099-Rs by type and by whether

they were partial or total (i.e., lump-sum) distributions. The $10 discrepancy that was

allowed in the reconciliation process resulted in a very slight undercount. Taxable pensions

and IRAs on the reconciled 1099-Rs were slightly below the amounts reported on Form

1040— pensions by 0.46 percent and IRA distributions by 0.12 percent.

This appendix presents tabulations of gross distributions, nontaxable distributions by type,

taxable distributions by type, and nonrollover distributions by type of plan. The following

plan types are included:

1. 401(k) plans,

2. 403(b) plans,

3. Employer-funded defined contribution plans,

4. All defined contributions plans (including items 1-3 above, plus the federal Thrift

Savings Plan),

5. Military retirement plans,

6. Federal civilian defined benefit plans,

7. State and local government retirement plans,

8. All government defined benefit plans (including items 5-7 above plus Railroad

Retirement in excess of the Social Security equivalent),

9. Private defined benefit plans,

10. Annuity payments by life insurance companies,
50

11. All pensions and annuities (including items 4, 8, 9, and 10 above), and

12. Individual retirement account distributions.

Numbers in these tables may not add up to totals due to rounding.
