Document:
Social Security’s receipts and expenditures are accounted for through two federal trust funds: the Federal Old-Age and Survivors Insurance (OASI) Trust Fund and the Federal Disability Insurance (DI) Trust Fund. Under their intermediate assumptions and under current law, the Social Security trustees project that the DI trust fund will become depleted in 2032 and the OASI trust fund will become depleted in 2034. Although the two funds are legally separate, they are often considered in combination. The trustees project that the combined Social Security trust funds will become depleted in 2034. At that point, the combined trust funds would become insolvent, because incoming tax revenue would be sufficient to pay only about 79% of scheduled benefits.
If a trust fund became depleted and current receipts were insufficient to cover current expenditures, there would be a conflict between two federal laws. Under the Social Security Act, beneficiaries would still be legally entitled to their full scheduled benefits. However, the Antideficiency Act prohibits government spending in excess of available funds, so the Social Security Administration (SSA) would not have legal authority to pay full Social Security benefits on time.
It is unclear what specific actions SSA would take if a trust fund were insolvent. After depletion, the trust funds would continue to receive tax revenues, from which a majority of scheduled benefits could be paid. One option would be to pay full benefits on a delayed schedule; another would be to make timely but reduced payments. Social Security beneficiaries would remain legally entitled to full, timely benefits and could take legal action to claim the balance of their benefits.
Maintaining financial balance after trust fund insolvency would require substantial reductions in Social Security benefits, substantial increases in tax revenues, or some combination of the two. The trustees project that following depletion of the combined funds in 2034, Congress could restore balance by reducing scheduled benefits by about 21%; the required reduction would grow gradually to 26% by 2092. Alternatively, Congress could raise the Social Security payroll tax rate from 12.4% to 15.7% following depletion in 2034, then gradually increase it to 16.7% by 2092.
Trust-fund insolvency could be avoided if expenditures were reduced or receipts increased sufficiently. The sooner Congress acts to adjust Social Security policy, the less abrupt the changes would need to be, because they could be spread over a longer period and would therefore affect a larger number of workers and beneficiaries. Even if changes were not implemented immediately, enacting them sooner would give workers and beneficiaries more time to plan and adjust their work and savings behavior.
What Happens to Benefits in the Case of Insolvency?
What If Congress Waits to Act?
Social Security's receipts and expenditures are accounted for through two federal trust funds: the Federal Old-Age and Survivors Insurance (OASI) Trust Fund and the Federal Disability Insurance (DI) Trust Fund. Under their intermediate assumptions and under current law, the Social Security trustees project that the DI trust fund will become depleted in 2032 and the OASI trust fund will become depleted in 2034. Although the two funds are legally separate, they are often considered in combination. The trustees project that the combined Social Security trust funds will become depleted in 2034. At that point, the combined trust funds would become insolvent, because incoming tax revenue would be sufficient to pay only about 79% of scheduled benefits.
Each year when the Social Security trustees release their annual report, attention is focused on the projection of the year that the Social Security trust funds will become depleted, that is, the year in which the trust funds' investment holdings in U.S. Treasury securities fall to zero.1 In their 2018 report, the trustees project that, under their intermediate assumptions and under current law, the Federal Disability Insurance (DI) Trust Fund will become depleted in 2032 and the Federal Old-Age and Survivors Insurance (OASI) Trust Fund will do so in 2034.2 Although the two funds are legally separate, they are often described in combination. The trustees project that the combined Old-Age, Survivors, Disability Insurance (OASDI) trust funds will become depleted in 2034.
Some Americans may believe that if the trust funds were depleted, Social Security would be unable to pay benefits at all. In fact, in 2034, the first year of projected depletion of the combined Social Security trust funds, the program is projected to have enough tax revenues to pay about 79% of scheduled benefits; that percentage would decline to 74% by the end of the 75-year projection period in 2092.3 Thus, although the trust funds would be insolvent upon depletion, because they would be unable to cover 100% of expenditures with incoming tax revenues, they would not be "completely broke" and unable to pay any benefits.
Although benefits would be paid in some form, it is unclear how the necessary reductions would be implemented, because the Social Security Act does not specify what would happen to benefits if a trust fund became insolvent. One option would be to pay full benefits on a delayed schedule; another would be to make timely but reduced payments.
Social Security's receipts and expenditures are accounted for through two legally distinct federal trust funds: the OASI trust fund and the DI trust fund. In the federal accounting structure, a trust fund is an accounting mechanism used by the Department of the Treasury to track and report receipts dedicated for spending on specific purposes, as well as expenditures made to its beneficiaries that are financed by those receipts, in accordance with the terms of a statute that designates the fund as a trust fund.9 The OASI trust fund records receipts and expenditures associated with retired workers, their dependents, and survivors of deceased insured workers, while the DI trust fund records receipts and expenditures associated with disabled workers and their dependents. The OASI and DI trust funds operate separately but are closely linked.10 Several times in the past, Congress has authorized the reallocation of the Social Security payroll tax rate to equalize the financial conditions of the two trust funds. In part because of those experiences, analysts often treat the two funds collectively on a hypothetical basis as the combined OASDI trust funds.
In 2017, the combined trust funds' total expenditures were $952.5 billion, with 98.8% for benefit payments and 0.7% for administrative expenses (see Appendix A). The remaining 0.5% was transferred to the Railroad Retirement Board (RRB) as part of a financial interchange with the RRB. This annual exchange of funds places the Social Security trust funds in the same financial position in which they would have been if railroad service had been covered by Social Security.
In years when Social Security's total receipts, including interest, exceed expenditures, then the trust funds have an annual surplus. By law, that surplus is invested in special-issue U.S. Treasury securities (i.e., nonmarketable government bonds), which are backed by the full faith and credit of the federal government. In other words, Social Security's cash surpluses are borrowed by the General Fund of the U.S. Treasury. The Treasury, in turn, incurs an obligation to repay the bonds with interest. These bonds are assets to the Social Security program but liabilities to the rest of the government. In 2017, the combined trust funds generated an annual surplus of $44.1 billion ($996.6 billion in total receipts minus $952.5 billion in total expenditures; see Appendix A).
An alternative measure of the trust funds' finances is given by the cash-flow balance. That measure does not consider interest income, so the trust funds run a cash-flow surplus when tax revenues exceed expenditures, and they run a cash-flow deficit when they spend more than they receive in taxes.
Total receipts for the combined trust funds in 2017 were $996.6 billion, with $911.5 billion in non-interest income (i.e., payroll taxes and income taxes on benefits) and $85.1 billion in interest income (see Appendix A). Because total expenditures for the combined trust funds in 2017 were $952.5 billion, there was a combined cash-flow deficit in 2017 of $41.0 billion ($952.5 billion in total expenditures minus $911.5 billion in non-interest income).
The balance of a trust fund is the accumulation of excess receipts over expenditures (i.e., the sum of annual surpluses less annual deficits). A positive balance denotes the total amount of the trust fund's investment holdings in U.S. government bonds (also known as asset reserves). Annual surpluses add to a trust fund's balance while annual deficits reduce it. The annual surplus of $44.1 billion in 2017 increased the trust funds' combined balance from $2.85 billion at the end of 2016 to $2.89 billion at the end of 2017 (see Appendix A).
If the trust funds are not able to pay all of current expenditures out of current tax revenues and accumulated trust fund assets, they are insolvent. Insolvency means that Social Security's trust funds are unable to pay benefits in full and on time. It does not mean that Social Security will be "completely broke" and unable to pay any benefits.
The OASI trust fund was created by the Social Security Act Amendments of 1939 (P.L. 76-379) and superseded the Old-Age Reserve Account established by the original Social Security Act in 1935 (P.L.74-271).19 The DI trust fund was established as part of the Social Security Amendments of 1956 (P.L. 84-880).20 Neither of the Social Security trust funds has ever become insolvent. The trust funds have existed on a hypothetical combined basis since the DI fund was first credited with receipts and debited for expenditures in 1957.
The trust funds have run annual surpluses in most years. Except for the first decades of the program and a few years beginning in the late 1960s, these annual surpluses were typically small relative to the size of the trust funds' expenditures. Beginning in 1975, the combined trust funds ran annual deficits. The trust funds made up the difference between receipts and expenditures during these years by redeeming some of the bonds accumulated in earlier years. In other words, in those years, the Social Security trust funds received net transfers from the Treasury's General Fund.
The aging of the baby-boom population and the recent recession and subsequent weak economy have resulted in higher expenditures and lower tax revenues for Social Security. Since 2010, the combined trust funds have run cash-flow deficits (Figure 1), which are projected to continue indefinitely under current law.

However, because interest income has exceeded the cash-flow deficit, the combined trust funds have continued to run annual surpluses, which averaged 5% of total expenditures from 2010 through 2017.21 Cash-flow deficits do not affect Social Security directly. However, if the non-Social Security portion of the federal budget is in deficit, redemption of trust fund bonds puts additional pressure on the overall federal budget.
In the early 1980s, a solvency crisis loomed for the OASI trust fund. The 1982 Social Security Trustees Report projected that in the absence of legislative changes, the OASI trust fund would become insolvent by July 1983.22 To relieve the pressure on the OASI trust fund temporarily, Congress permitted the fund to borrow from the DI and HI trust funds through the end of 1982.23 On November 5, 1982, the Department of the Treasury announced that the balance of the OASI trust fund had fallen to zero, and that the U.S. Treasury would be unable to redeem the amount of bonds necessary to cover the OASI benefit checks that had been delivered on November 3.24 To cover the shortfall, the Secretary of the Treasury authorized a $581 million loan from the DI trust fund to the OASI trust fund. Additional loans from the DI and HI trust funds to the OASI trust fund were made before the temporary interfund borrowing authority expired.
On November 2, 2015, President Barack Obama signed into law the Bipartisan Budget Act of 2015 (BBA 2015; P.L. 114-74). Among other provisions, the BBA 2015 authorized a temporary reallocation of the payroll tax rate between the OASI and DI trust funds to provide DI with a larger share for 2016 through 2018. Specifically, the DI trust fund's share of the combined tax rate increased by 0.57 percentage points at the beginning of 2016, from 1.80% to 2.37%. Because the BBA 2015 did not change the combined payroll tax rate of 12.40%, the portion of the tax rate allocated to OASI decreased by a corresponding amount. This means that OASI's share of the combined tax rate declined by 0.57 percentage points at the start of 2016, from 10.60% to 10.03%. For 2019 and later, the shares allocated to the DI and OASI trust funds are scheduled to return to their 2015 levels: 1.80% to the DI trust fund and 10.60% to the OASI trust fund.
To put the trust fund balance in context, analysts commonly consider the trust fund ratio: the balance in the trust funds at the beginning of a year divided by projected expenditures for that year. The trust fund ratio thus represents the proportion of a year's cost that could be paid solely with the reserves at the beginning of the year. The ratio for the combined trust funds peaked at 358% in 2008 (Figure 2). The combined trust fund ratio declined to 299% in 2017 and is continuing to fall. By definition, the ratio will reach zero when the trust funds become depleted.

The Social Security Act specifies that benefit payments shall be made only from the trust funds (i.e., only from their accumulated bond holdings).35 Another law, the Antideficiency Act, prohibits government spending in excess of available funds.36 Consequently, if the Social Security trust funds become insolvent—that is, if current tax receipts and accumulated assets are not sufficient to pay the benefits to which people are entitled—the law effectively prohibits full Social Security benefits from being paid on time.
The Social Security Act states that every individual who meets program eligibility requirements is entitled to benefits.37 Social Security is an entitlement program, which means that the federal government is legally obligated to pay Social Security benefits to all those who are eligible for them as set forth in the statute.38 If the federal government fails to pay the benefits stipulated by law, beneficiaries could take legal action. Insolvency would not relieve the government of its obligation to provide benefits.
The Antideficiency Act prohibits government agencies from paying for benefits, goods, or services beyond the limit authorized in law for such payments. The authorized limit in law for Social Security benefits is the balance of the trust fund. The Social Security Act does not stipulate what would happen to benefit payments if the trust funds ran out. As a result, either full benefit checks may be paid on a delayed schedule or reduced benefits would be paid on time.39 In either case, total payable benefits would be lower than scheduled benefits.

Note: For beneficiaries scheduled to receive payments on the third of the month, benefits may be paid earlier if the third is on a weekend or holiday.
If trust fund insolvency caused delays in the payment schedule, benefit payments could be made in the usual order—first to those who receive benefits on the third of the month, then to those on the second Wednesday of the month, and so on, until the remainder of the trust funds' balance reached zero. At that point, no benefits could be paid until more tax receipts were credited to the trust funds. Then benefit payments could be picked up where they left off when the trust funds ran out. This cycle could continue indefinitely. The timing of these payments would be unpredictable.
There are many options to restore Social Security solvency, which could be combined or targeted in a variety of ways. For example, Congress could decrease Social Security benefits. Benefit cuts could be applied proportionately to all beneficiaries or structured to protect certain people, such as disabled or low-income beneficiaries. Congress could also increase Social Security's income by raising payroll or other taxes or by transferring funds from the Treasury's general fund. Payroll tax increases could be applied proportionately to all workers or targeted to certain workers, such as those who earn more than the taxable maximum ($128,400 in 2018).
the tax increase scenario, under which the payroll tax rate would increase.
Both scenarios assume that current law would remain in place until the combined trust funds became insolvent. If changes were made sooner, they could be smaller, since the burden of lower benefits or higher taxes would be shared by more beneficiaries or workers over a longer period.42 Either scenario would essentially convert Social Security to a pure pay-as-you-go system, in which income and outgo are equal on an annual basis and there are no trust fund assets. These scenarios are only two of a wide range of possibilities. When Congress last addressed Social Security's solvency in 1983, lawmakers employed a combination of tax increases and benefit reductions to improve the financial condition of the combined trust funds.
If the trust funds were allowed to run out, Congress could eliminate annual cash-flow deficits by cutting benefits so that spending equals tax income on an annual basis. According to the trustees, achieving annual balance would require benefit cuts of 21% in 2034, the first year of insolvency, rising to 26% by 2092.43 To maintain balance after 2092, the Social Security trustees project that larger benefit reductions would be needed, because people would continue to live longer and therefore collect benefits for longer periods.
Figure 3 shows the percentage of scheduled benefits that are payable each year with scheduled revenues. One way to understand how such a reduction would affect beneficiaries is to examine the effect on projected replacement rates and real benefit amounts for hypothetical workers.
Source: CRS, based on an OCACT memorandum from Daniel Nickerson, actuary, and Kyle Burkhalter, actuary, to Chris Chaplain, supervisory actuary, and Karen Glenn, deputy chief actuary, "Present-Law OASDI Payable Percentages: Present-Law Revenue as a Percent of the Cost of Providing Scheduled Benefits Through Year 2092—Information," June 11, 2018 (hereinafter "2018 OCACT Payable Benefits Memo").
Notes: Projections are based on the trustees' 2018 intermediate assumptions. In calculating the share of payable benefits, OCACT limits revenue from the taxation of benefits to the amount that would be obtained from the payable benefits.
Social Security was established to replace income lost to a family as a result of the retirement, death, or disability of a worker. To ensure that average benefit levels grow along with average wages—thus keeping replacement rates generally steady—initial Social Security benefits are indexed to wage growth. Historically, wages have generally risen faster than prices, allowing the standard of living to rise from one generation to the next.

Notes: Projections are based on the trustees' 2018 intermediate assumptions. Replacement rates are for hypothetical earners who claim retirement benefits at their full retirement age.
Another measure of benefit adequacy is initial annual benefit amounts. Since benefits are based on workers' lifetime earnings, higher earners tend to receive higher benefit amounts than lower earners. In 2018, a hypothetical low earner is estimated to receive an annual Social Security benefit of $12,531, a medium earner a benefit of $20,662, and a high earner a benefit of $27,374.48 Figure 5 shows future initial real benefit amounts in 2018 dollars (i.e., after adjusting for inflation), which illustrates how the purchasing power of benefits will change over time.
Source: CRS analysis of data from 2018 OCACT Payable Benefits Memo and 2018 Social Security Trustees Report, Table V.C7 (Supplemental Single-Year Table).
Notes: Projections are based on the trustees' 2018 intermediate assumptions. Benefits are for hypothetical earners who claim retirement benefits at their full retirement age. After insolvency, scheduled benefits would continue to increase because average real earnings are projected to continue to grow. Payable benefits would therefore also grow over time following the drop upon insolvency, though they would be permanently lower than scheduled benefits. For clarity, scheduled benefits are shown only for high earners.
Upon trust fund depletion, the system could also be balanced by raising the payroll tax rate so that the tax income would be sufficient to pay scheduled benefits each year.
The trustees project that paying scheduled benefits after depletion in 2034 would require an increase in the combined employee and employer payroll tax rate of 3.3 percentage points, from the current 12.4% to 15.7%, after insolvency in 2034.52 To sustain balance, the payroll tax rate would have to reach 16.7% by 2092, the last year of the 75-year projection period.53 Figure 6 shows the combined payroll tax rate under current law and the combined payroll tax rate needed to pay scheduled benefits from 2018 to 2092.
Source: CRS analysis of data from 2018 Social Security Trustees Report, Table IV.B1 (Supplemental Single-Year Table).
Notes: Projections are based on the trustees' 2018 intermediate assumptions. Under the trustees' projections, the current 12.4% combined payroll tax rate is sufficient to pay scheduled benefits prior to 2034 on a combined basis.
Raising the payroll tax rate would increase most workers' taxes by the same proportion. However, because covered earnings are taxable only up to a specified maximum ($128,400 in 2018), the effective increase in the payroll tax would be smaller in percentage terms for people who earn more than the taxable maximum than for other workers. Unlike the federal income tax, the Social Security payroll tax is levied at a flat rate starting at the first dollar of earnings.
Under current law, the Social Security trust funds will almost certainly become insolvent. The sooner changes are made to the program, the smaller and less abrupt the changes would need to be to maintain solvency. Prompt action would also allow Congress to gradually phase in changes, rather than abruptly cutting benefits or raising taxes, thus allowing workers to plan in advance for their retirements.

The Social Security Board of Trustees presents an annual report to Congress on the current and projected financial status of the Social Security trust funds (see 42 U.S.C. §401[c]). The board is composed of six members: the Secretary of the Treasury, who is the Managing Trustee; the Secretary of Labor; the Secretary of Health and Human Services; the Commissioner of Social Security; and two public representatives, who are nominated by the President for a term of four years and subject to confirmation by the Senate. The trustees specify the assumptions about future demographic and economic trends used in the projections; however, the Social Security Administration's (SSA) Office of the Chief Actuary (OCACT) advises the trustees on the assumptions as well as develops and runs the computer models that produce the forecasts.

Taxable payroll is the total amount of earnings in the economy that is subject to Social Security payroll taxes (with some adjustments).
To estimate the future financial status of the trust funds, the Social Security trustees produce short-range and long-range actuarial projections under three sets of economic and demographic assumptions: intermediate, low-cost, and high-cost. Intermediate assumptions represent the trustees' best estimate of the financial condition of the trust funds in the future. The low-cost and high-cost sets of assumptions, on the other hand, depict extraordinarily favorable (low-cost) or unfavorable (high-cost) possibilities for the trust funds' future solvency. According to the trustees, "actual future costs are unlikely to be as extreme as those portrayed by the low-cost and high-cost projections" (2018 Social Security Trustees Report, p. 18). Unless otherwise specified, projections cited in this report are based on the trustees' intermediate assumptions.

The 1982 Trustees Report, which projected impending trust fund insolvency, stated that unless legislative changes were made, "inability to pay some benefits on time would result" (1982 Social Security Trustees Report, p. 2 [emphasis added]). That language suggests that after insolvency, full benefit payments would have been made on a delayed schedule. The 2018 report uses more neutral language, stating that after insolvency, the trust funds would be "unable to pay scheduled benefits in full on a timely basis" (2018 Social Security Trustees Report, p. 5).
20 C.F.R. §404.1807. For the payment schedule rationale, see SSA, "Cycling Payment of Social Security," 62 Federal Register 6114, February 11, 1997, https://www.gpo.gov/fdsys/pkg/FR-1997-02-11/pdf/97-3205.pdf.
For beneficiaries who receive Social Security benefits based on another person's work record (e.g., spousal benefits), their payment date depends on the birth date of the worker on whose record they receive benefits. The current benefit payment schedule was first implemented for new beneficiaries in May 1997.
The trustees estimate that 75-year solvency could be restored through (1) an immediate payroll tax increase of 2.78 percentage points (from the current 12.40% to 15.18%), (2) a benefit reduction of 17% for all current and future beneficiaries, (3) a benefit reduction of 21% for only those who become initially eligible for benefits in 2018 or later, or (4) some combination of those approaches. If Congress waited until 2034 to act, the trustees estimate that maintaining solvency over the 75-year projection period would require (1) a payroll tax increase of 3.87 percentage points (from the current 12.40% to 16.27%) starting in 2034, (2) a reduction in scheduled benefits of 23% starting in 2034, or (3) some combination of those approaches. See 2018 Social Security Trustees Report, pp. 4-5.
Under the Social Security program, the replacement rate for retired workers is the ratio of the Social Security benefit to the average of the highest 35 years of covered earnings, indexed to wage growth using the SSA's Average Wage Index (AWI). Other ways to measure replacement rates are discussed in Andrew G. Biggs and Glenn R. Springstead, "Alternate Measures of Replacement Rates for Social Security Benefits and Retirement Income," Social Security Bulletin, vol. 68, no. 2, October 2008, http://www.ssa.gov/policy/docs/ssb/v68n2/v68n2p1.html, and in SSA, OCACT, Replacement Rates For Retirees: What Makes Sense For Planning And Evaluation?, Actuarial Note 155, July 2014, at http://www.ssa.gov/oact/NOTES/pdf_notes/note155.pdf.
The low earner is assumed to have earned 45% of the national average wage (or $23,353 in 2018) when working and to receive an annual Social Security benefit of $12,531 in 2018. The medium earner is assumed to have earned the average wage (or $51,894 in 2018) and to receive a benefit of $20,622 in 2018. The high earner is assumed to have earned 160% of the average wage (or $83,031 in 2018) and to receive a benefit of about $27,374 in 2018.

Immediately before the trust funds become insolvent in 2034, annual scheduled real benefits for individuals retiring at their full retirement age are projected to be $16,069 for the low earner, $26,504 for the medium earner, and $35,081 for the high earner. The annual payable real benefits would be 79% of these amounts. See 2018 Social Security Trustees Report, Table V.C7, (Supplemental Single-Year Table).

Ibid. Under the tax rate increase scenario discussed in this report, the payroll tax rate would have to change each year, increasing in some years and decreasing in others. Alternatively, the payroll tax rate could be permanently increased by 3.87 percentage points starting in 2034 (from 12.40% to 16.27%) to maintain solvency over the 75-year projection period. See footnote 42.
