Estate Tax Options
Released: 2010-12-23T00:00:00

Summary:
The Economic Growth and Tax Relief Reconciliation Act of 2001 (EGTRRA; P.L. 107-16), among other tax cuts, provided for a gradual reduction and elimination of the estate tax. Under EGTRRA, the estate tax exemption rose from $675,000 in 2001 to $3.5 million in 2009, and the rate fell from 55% to 45%. In 2010, the estate tax was eliminated. The estate tax changes, however, were scheduled to sunset in 2011, when the exemption would have become $1 million (as scheduled in pre-EGTRRA law) and the tax rate would return to 55%.
There was general agreement that some sort of estate tax would be retained. A proposal to make the 2009 rules ($3.5 million exemption and 45% rate) permanent was included in President Obama's 2010 and 2011 budget outlines and was passed by the House in December 2009 (H.R. 4154). Senate Democratic leaders supported the plan to enact the 2009 rules permanently (and make them retroactive to 2010). The Senate Republican leadership proposed a $5 million exemption and 35% rate. This latter provision was adopted for a two-year period, through 2012. At that point the exemption will revert to the pre-EGTRRA law. For estates of decedents in 2010, either the 2010 or 2011 rules can be elected. Spouses can inherit unused exemptions.
With any of the exemption levels, few estates are affected by the tax. In 2011, the shares of estates taxed are projected by one study to be 1.76%, 0.25%, and 0.14% for the exemption levels of $1 million, $3.5 million, and $5 million, respectively. These numbers would grow to 3%, 0.46%, and 0.23% by 2019. The revenue yield in 2011 is projected to be $34.4 billion, $18.2 billion, and $11.4 billion for the $1 million exemption/55% rate, $3.5 million exemption/45% rate, and the $5 million exemption/35% rate. The estate tax accounts for a small share of revenue.
The estate tax is a highly progressive tax; it not only applies to the largest estates, but within the distribution of estates a large share is concentrated in the over $20 million estate level: 72% for the $5 million/35% rate. Because of exclusions, the effective tax rates are smaller than the statutory rate, with an average of 14% for the $5 million exemption/35% rate. When distributed with respect to income, 96% falls in the top quintile of the income distribution, 72% in the top 1%, and 42% in the top 0.1%, under the $3.5 million exemption/45% rate.
Although concerns have been raised about the effects of the tax on small businesses and farmers, estimates indicate that the share of estate taxes paid by small business estates under the proposed revisions would be small (16% to 18%) and the share of estates of small business owners taxed is small (about 0.2% of decedents with at least 50% of their assets in businesses). Evidence suggests that the number of returns with inadequate liquid assets to pay the estate tax is negligible.
Other effects are likely small. The effects on savings are uncertain but likely small relative to the economy because the tax is small. Moving to either the $3.5 million plan or the $5 million plan would be projected to decrease charitable contributions by a small amount: 1% to 2%. Recent evidence suggests that the costs of administration and compliance are around 7% of revenues.
Structural reforms that might be considered are inheritance of spousal exemptions, and some reforms directed at abuses. A provision to restrict Grantor Retained Annuity Trusts (GRATS), which can be used to virtually eliminate estate tax by providing an annuity with a remainder, is contained in H.R. 4849. Other provisions in President Obama's budget outline include restricting discounts for estates left to family partnerships and conforming fair market value for purposes of the estate tax and future capital gains realizations for heirs.

subsections: section_title: Introduction
paragraphs: The Economic Growth and Tax Relief Act of 2001 (EGTRRA; P.L. 107-16 ), among other tax cuts, provided for a gradual reduction in the estate tax. The estate tax applies to wealth transferred at death and had, at that time, a unified exemption for both lifetime gifts and the estate of $675,000.
Under EGTRRA, the estate tax exemption rose from $675,000 in 2001 to $3.5 million in 2009, and the top tax rate fell from 55% to 45%. Although combined estate and gift tax rates are graduated, the exemption is effectively in the form of a credit that eliminates tax due at lower rates so there is a flat rate on taxable assets under 2009 law. The gift tax exemption was, however, restricted to $1 million. 
For 2010, EGTRRA scheduled the elimination of the estate tax, although it retained the gift tax and its $1 million exemption. EGTRRA also provided for a carryover of basis for assets inherited at death, so that, in contrast with prior law, heirs who sold assets would have to pay tax on gains accrued during the decedent's lifetime. This provision has a $1.3 million exemption for gain (plus $3 million for a spouse).
As with other provisions of EGTRRA, the tax revisions expire in 2011, returning the tax provisions to their pre-EGTRRA levels. The exemption would revert to $1 million (a value that had already been scheduled for pre-EGTRRA law) and the rate to 55% (with some graduated rates). The carryover basis provision effective in 2010 would be eliminated (so that heirs will not be taxed on gain accumulated during the decedent's life when they inherit assets).
During debate on the estate tax, most agreed that the 2010 provisions would not be continued, and, indeed, could be repealed retroactively. President Obama proposed a permanent extension of the 2009 rules (a $3.5 million exemption and a 45% tax rate), and the House provided for that permanent extension on December 3, 2009 ( H.R. 4154 ). The Senate Democratic leadership has indicated a plan to retroactively reinstate the 2009 rules for 2010 and beyond. Senate Minority Leader McConnell proposed an alternative of a 35% tax rate and a $5 million exemption. A similar proposal for a $5 million exemption and a 35% rate, which also includes the ability of the surviving spouse to inherit any unused exemption of the decedent, is often referred to as Lincoln-Kyl after the two Senators who have supported it. Proposals have also been to begin with the $3.5 million/45% rate and phase in the $5 million/55% rate. Others have argued for a permanent estate tax repeal. At the end of 2010, a temporary extension for two years, with a $5 million exemption, a 35% rate, and inheritance of unused spousal exemptions was enacted in P.L. 111-312 . At the end of 2012, absent legislation, the provisions will revert to the pre-EGTRRA rules ($1 million exemption, 55% top rate).
To address abuses and tax avoidance, President Obama has included proposals in his 2011 budget outline. One of these proposals, to reform the Grantor Retained Annuity Trust (GRAT), is included in H.R. 4849 . This provision is discussed in detail below.
After a brief description of the estate and gift tax and of options, this report compares the alternatives, focusing largely on a $1 million exemption and 55% rate, a $3.5 million exemption and a 45% rate, and a $5 million exemption and a 35% rate. Several policy effects and issues are analyzed: the share of decedents subject to tax; revenue effects; distributional effects; and effects on savings, charitable contributions, and compliance and administration. The report also considers other aspects of the proposals, such as whether the exemptions are indexed for inflation, a proposed inheritance of the exemption for spouses (which applies under the new rules to 2011 and 2012), and proposals to address perceived abuses.
section_title: Brief Description of the Estate Tax
paragraphs: This section describes the estate tax as it existed in 2009 and will exist in future years, absent legislative change. For 2010, there is no estate tax, although the gift tax remains and there is a tax on gains accumulated during the decedent's lifetime when assets are sold by heirs (with a $1.3 million exemption plus $3 million for a spouse). An election can be made for 2010 to apply either 2010 or 2011 rules. Because the exemption from gains is smaller than the overall estate tax exemption for 2011, some estates would have lower tax liability by electing the 2011 rules.
subsections: section_title: Basic Structure
paragraphs: The estate and gift tax is a unified tax, so that assets transferred as gifts during a person's lifetime are combined with those transferred at death (bequests) and subject to a single rate schedule. The tax is imposed on the decedent's estate and the rate structure applies to total bequests and gifts given; heirs are not subject to tax. In the past, a single effective exemption applied, but under the 2001 tax revisions effective in 2009, the gift tax exemption was more limited than the combined exemption for both estate and gift taxes. Thus, although a unified rate schedule applies to both bequests and gifts, the exemptions differed in 2009. The combined exemption was $3.5 million, whereas the exemption for gifts was $1 million. For 2011 and 2012, the combined exemption is $5 million and that exemption applies to gifts as well. In 2013, the combined exemption will be $1 million, absent legislative change.
Although the rates of the tax are graduated, the exemption is applied in the form of a credit and offsets taxes applied at the lower rates, under the 2009 and the 2011-2012 rules. Thus the taxable estate was subject to a flat 45% rate in 2009 and will be subject to a flat 35% rate in 2011-2012. Under pre-EGTRRA law, which will apply in 2013, absent legislation, there are some graduated rates on taxable estate amounts between $1 million and $3 million because the exemption is not large enough to offset tax at lower rates. Rates begin at 41% for amounts over $1 million and rise by 2 percentage points at each additional $500,000, reaching 53% on amounts between $2.5 million and $3 million. There is also a 5% surtax designed to phase out the benefits of lower rates so that very large estates are taxed at a flat 55% rate. Individuals are also allowed to exempt annual gifts of $13,000 per recipient, which are not counted as part of the lifetime exemption. The annual gift tax exemption is indexed for inflation in $1,000 increments. A generation skipping tax is also imposed, to address estate tax avoidance through gifts and bequests to a later generation.
section_title: Exemptions and Deductions
paragraphs: Estates are allowed to exempt some assets from the estate tax and take a deduction for selected other transfers. Transfers between spouses are exempt. Estates are also allowed to take deductions for charitable contributions and administrative expenses. Currently estates are also allowed a deduction for taxes paid on estates and inheritances imposed by states. Prior to 2001, a credit was allowed, subject to a cap, for state estate taxes, but the credit was phased out and replaced by a deduction in that legislation. (Should EGTRRA provisions expire, the state credit would reappear.)
Under the rules for 2011 and 2012, a spouse can inherit any unused exemption. Thus if a husband dies and leaves an estate of $3 million, the remainder of his $5 million exemption can be used by his wife, whose exemption would be increased by the $2 million difference. 
section_title: Special Provisions for Small Businesses, Farms, and Landowners
paragraphs: A series of provisions benefit small businesses, including farms or landowners. These include the ability of family businesses to pay the tax in installments with only interest payments during part of the installment period, special use valuation, conservation easements, and, if the law reverts to its 2001 rules, a deduction for family owned business assets. Minority discounts, although granted by courts rather than specifically in the law, may also benefit small businesses.
Although the estate tax return is due within nine months of the death, small businesses are allowed to defer payment (except for interest) for the next five years, and pay the remaining installment payments over 10 years. Since the last interest payment and the first installment coincide, the overall delay in full payment is 14 years. The benefit is allowed only for the business portion of assets and only if 35% of the estate is in a farm or closely held business.
Small businesses are also allowed to value their assets at use as a farm or business. This provision is particularly beneficial to farms and allows a reduction in the estate value of up to $1 million. It means, for example, that the value of the farm will be what it could be sold for if restricted to farm use rather than, for example, to be subdivided for development. Heirs are required to continue use as a farm or business for 10 years.
Farmers and other landowners may also benefit from conservation easements, a perpetual restriction on the use of the land where, in addition to the reduction in value due to the easement itself, an exclusion of up to 40% of the restricted value of the land, capped at $500,000, is allowed.
In prior law, another provision benefitting small businesses was the Qualified Family Owned Business Income (QFOBI) deduction. This provision allowed estates with at least half of their assets in a family business to take a deduction for these business assets. This provision originally allowed up to $675,000 of business deductions at a time when the basic estate tax exemption was $625,000, and imposed an overall cap of $1.3 million on the total of both deductions. Once the regular exemption passed the $1.3 million level, the provision was no longer relevant. If the 2001 tax cuts sunset in 2013, the exemption will become $1 million and QFOBI will be relevant again, allowing an additional $300,000 exemption. With the $5 million exemption for 2011 and 2012, this provision is ineffective. To qualify for the QFOBI deduction, heirs must continue the business for 10 years or the tax saving must be repaid.
section_title: Step Up in Basis for Appreciated Assets
paragraphs: Heirs take as their basis (the amount to be deducted from the sales price) for purposes of future capital gains the value of the asset at the date of the decedent's death. This treatment is referred to as step-up in basis and means that no capital gains tax is paid on the appreciation of assets during the decedent's lifetime. For example, if decedent purchased stock for $100,000 and the value of the stock at the time of death is $200,000, if the heir sells the property for $250,000 a gain of $50,000 ($250,000 minus the stepped-up basis of $200,000) is recognized. The $100,000 of gain that accrued during the decedent's lifetime is never taxed. The step up rules do not apply to gifts, where carryover basis is applied. In that case, the original basis of $100,000 would be carried over and the gain would be $150,000 ($250,000 minus $100,000). Both the gain accrued by the donor and the gain accrued by the donee are taxed. The step-up rules do not apply to bequests for 2010, if 2010 rules are elected, where carryover basis, with an exemption, applies, as noted above.
section_title: Differences in the Treatment of Bequests and Gifts
paragraphs: Aside from the different exemption levels in some estate tax rules, there are other differences between the taxation of gifts and bequests. As noted above, gifts do not benefit from the step up in basis. The donor takes the basis in the hands of the donor, generally the original cost of acquiring the assets. The basis cannot be less than the fair market value at the time of the gift if a loss is realized.
At the same time, the gift tax is tax exclusive (the tax is imposed on the gift net of the tax) whereas the estate tax is tax inclusive (the tax is applied to the estate inclusive of the tax). To illustrate, consider a 50% tax rate. Assuming the exemption is already used, to provide a gift of $1 million costs $1.5 million: the tax rate of 50% is applied to the gift of $1 million for a $0.5 million tax. To provide a net amount of $1 million for a bequest, $2 million is required: a tax of $1 million (50% of $2 million) and a net to the heir of $1 million. Another way of stating this is that the gift tax rate, if stated as a tax inclusive rate like the estate tax, would be 33%. Thus for the 55%, 45%, and 35% estate tax rates, the gift tax rate equivalents are 35%, 31%, and 26%.
section_title: Options for Revision
paragraphs: The principal components of any policy that continues the estate tax are the amount of the exemption and the tax rate. As indicated earlier, the exemption in 2009 was $3.5 million, the exemption is scheduled at $5 million for 2011 and 2012, and in 2013 the estate tax will revert to an exemption of $1 million, absent a change in the statute. Thus, while any level of exemption might be considered, the two most common levels mentioned are $3.5 million and $5 million. The level of the exemption affects not only the revenue but the number of estates that are subject to the tax.
The second principal component of a continued estate tax is the rate, which will return to 55% in 2013 absent legislative change; rates of 45% applied in 2009 and a 35% rate applies in 2011-2012. Some proposals would apply the capital gains tax rate (currently 15% but scheduled to go to 20% in 2013) or some multiple of it.
Another issue is whether to index the exemption for inflation. Some components of the income tax, such as rate brackets and standard deductions, are indexed, while others (such as child credits) are not. Over time, as prices rise, a fixed exemption causes more estates to be subject to tax. Without indexation, Congress may return from time to time to reconsider the exemption.
A final issue is the potential carryforward of an unused estate tax exemption to the surviving spouse. The provision, adopted in recent legislation for 2011 and 2012, would allow spouses to inherit unused estate tax exemptions. Since bequests to the spouse are excluded from the estate, the couple together can have a larger total exemption if the first spouse to die leaves assets to the children or other heirs large enough to absorb his or her estate exemption. This action will reduce the size of the estate subject to tax when the second spouse dies. There are reasons, however, that the taxpayer may prefer to leave more assets to a spouse (for example, if there are concerns about having enough assets to live in comfort or cover emergencies). The proposed change is to permit the second spouse to inherit any unused exemption and add it to his or her own future exemption.
Proposals have also been made to increase the percentage or dollar limits of special use valuations and conservation easements. At the same time, there are proposals, including those in President Obama's budget, to restrict practices considered as abuses. One proposal, relating to a certain type of trust (a Grantor Retained Annuity Trust or GRAT) was adopted in H.R. 4849 , the Small Business and Infrastructure Jobs Tax Act of 2010. Another proposal would restrict minority discounts for estates that are sometimes allowed by courts when no one heir has a controlling interest in the property. A third provision would require estates and heirs use the same fair market value in determining the valuation for purposes of the estate tax and for determining basis in the hands of the heir.
section_title: An Introduction to the Issues
paragraphs: Data, other empirical evidence, and economic theory can help address proposals to revise the estate tax. Relevant economic issues include the scope and effect of the tax on the total population and the distribution of the tax, the revenue yield, and the potential effects on family businesses, savings, administration and compliance, and charitable giving. To the extent possible, different options are compared in the context of these issues.
Other issues are perhaps more philosophical or, as Gale and Slemrod discuss in their article on the estate tax, rhetorical. For example, some people oppose the estate tax because they hold a philosophical view that the estate tax is a death tax and death should not be taxed. Arguments are also made that estate taxes result in a double tax, because assets have already been taxed under the income tax and should not be taxed again. Gale and Slemrod do point out, however, the complexity of the rhetorical questions. For example, they point out that for the vast majority of people (at the time they were writing, 98%) death actually brings potential tax benefits through the forgiveness of tax on accrued but unrealized gains (gains on assets that have not been sold). They also note that income from unrealized appreciation in assets is not taxed during the lifetime and so is not subject to double taxation. They indicate that 36% of estate assets and 80% of the wealth in closely held business and farm estates is from unrealized appreciation.
Supporters of the estate tax may believe it is important to constrain the accumulation of wealth generation after generation. While empirical evidence can demonstrate that the estate tax is highly progressive, the degree to which taxes should be applied to large amounts of wealth in pursuit of reducing inequality in society, much like the question of whether it is wrong for death to trigger a tax, is a value judgment.
subsections: section_title: Coverage of Decedents
paragraphs: The estate tax has never affected more than a small fraction of decedents. Table 1 indicates that if the law reverts to the $1 million exemption, less than 2% of decedents would pay an estate tax. Table 1 also indicates that restoring the $3.5 million exemption leads to a quarter of 1% of decedents paying the tax. Moving to a $5 million exemption reduces the share to 0.14%. The column for 2019 illustrates the effects of indexing the $3.5 million and the $5 million for inflation, starting from 2009. Note that even with indexing for inflation, real asset growth leads to an increased share of decedents paying the estate tax. With or without indexing, the $3.5 million option will affect less than one-half of 1% of decedents and the $5 million option will affect less than one-fourth of 1% of decedents. If the main focus of legislation is to exclude all but a small fraction of estates from the tax, the $3.5 million exemption and the $5 million exemption accomplish that goal, and indexing does not matter very much over short time horizons.
section_title: Liabilities and Revenue Loss
paragraphs: An issue in the choice of estate tax provisions is the revenue cost. Although the estate tax accounts for a small share of total federal revenues, 1.3% in 2012 if the $1 million exemption/55% rate provisions are retained, concerns remain about revenue losses.
Revenue costs are normally estimated against a current law baseline. Thus, the cost of keeping the 2009 rules in place retroactively to 2010, with a $3.5 million exemption and a 45% tax rate, would be compared to no estate tax in 2010; therefore there would be a revenue gain compared to no estate tax. In subsequent years, where current law reverts to a larger estate tax (a $1 million exemption and 55% rate) the smaller estate tax will lead to a revenue loss. Receipts are also measured when they flow into the Treasury and there is a delay in the filing of estate tax returns. The Joint Committee on Taxation (JCT) in 2009 estimated a gain of $0.5 billion in FY2010, then a loss, rising to $38 billion in FY2019 for a total of $234 billion over the 10-year period (FY2010-FY2019) from retaining the 2009 exemptions. Treasury's estimates are smaller, with a $3 billion and a $1 billion gain respectively in the first two fiscal years, becoming a $28 billion loss by FY2019, and losing $171 billion over a 10-year period.
Another way to examine the alternatives is to look at the estimated yield for alternative proposals, that is, the liability rather than the flow of revenue to the Treasury. Table 2 provides data from the Urban Brookings Tax Policy Center for the three exemption levels. In 2011, the scheduled rules ($1 million exemption, 55% rate) are estimated to produce a liability of $34.4 billion; the $3.5 million exemption, 45% rate a revenue of $18.2 billion, and the $5 million exemption/35% rate a revenue of $11.4 billion. Thus, in 2010, the reduced liability from moving to a $3.5 million exemption with a 45% rate is $16.3 billion, whereas moving to the $5 million exemption with a 45% rate loses an additional $6.9 billion, for a total of $26.2 billion. The cost increases over time as the real and nominal value of wealth grows, so that, for example, the reduction in tax from moving to a $3.5 million exemption and 45% rate increases from $16.3 billion in 2011 to $30.7 billion in 2019. 
 Table 2 also contains estimates of estate tax liability if exemptions are indexed (assuming indexing back to 2009). Indexing does not make a great deal of difference over this time period. Real growth in wealth is more important. For example, the difference between revenues in 2011 and 2019 for the $3.5 million exemption/45% rate is $13.4 billion but only $2.6 billion of the difference is due to lack of indexing for inflation.
The estimates in Table 2 indicate that the difference between the $1 million, 55% rate and the $5 million, 35% rate would be $23.2 billion ($34.4 minus $11.2), in turn suggesting a cost for two years of $46 billion. The Joint Committee on Taxation (JCT) has estimated the cost of the estate tax revisions at $68 billion. Some of this difference may reflect differences in data and projections, but the JCT estimates would also be increased because of the increase in the gift tax exemption and the ability to inherit exemptions. For example, if a husband or wife left all assets to his or her spouse, the maximum exemption of the second spouse would be larger by $5 million.
As indicated above, the two proposals generally discussed during the 111 th Congress were the $3.5 million exemption and 45% tax rate, and the $5 million exemption and 35% tax rate. However, various combinations of rates and exemptions could be considered. Table 3 reports the estimates of estate tax liability for each of the three exemption levels at different rates. It shows that, compared with the default $1 million exemption, a larger amount of the revenue loss results from moving to the $3.5 million exemption rather than the 45% rate. Similarly, in moving from the $1 million to the $5 million exemption, the cost of the exemption increase is smaller than lowering the rate to 35%. However, once the exemption is set at $3.5 million and the rate at 45%, the cost of moving to a $5 million exemption ($14.2 billion) is about the same as the cost of moving to a 35% tax rate ($14.1 billion).
The rate reductions tend to benefit, relatively, a wealthier group of estates than exemptions, and thus reduce progressivity of the estate tax. However, rate reductions also reduce the average marginal tax rate more than exemption increases, which could matter for economic efficiency. These distributional issues are discussed more fully in the next section.
section_title: Distributional Issues
paragraphs: One of the rationales for an estate tax is to impose a tax on high income and high wealth taxpayers, and contribute to the progressivity of the tax system. As indicated in the discussion of coverage, all of the proposals fall on a small proportion of decedents and thus, due to the size of the exemption level, on those with the greatest wealth. The alternative proposals have different effects on the size of estates covered and the distribution of taxes.
As indicated in Table 4 , the number of estates is concentrated in the smaller estates. With the $1 million exemption, about half of the estates subject to tax have assets of under $2 million and almost 80% have assets of under $3.5 million, and these estates would be eliminated from estate tax coverage with either the $3.5 million or the $5 million exemption. With a $3.5 million exemption, the share of taxable estates under $5 million is smaller than the share falling between $5 million to $10 million group. Of the returns taxed under the $3.5 million exclusion, 23% are less than $5 million in assets and would not be taxed under the $5 million exclusion. 
As shown in Table 5 , revenue from the estate tax is more concentrated in larger estates. The largest share of revenue is in the $20 million and above class regardless of the exemption. With a return to the $1 million exemption that class would pay one-third of the revenue; with a $3.5 million exemption it would pay over 60%; and with a $5 million exemption it would pay almost three-quarters of the estate tax. These estimates indicate that the estate tax not only applies to high wealth families, but with either the $3.5 million or the $5 million exemption more than half the revenue is collected from estates with $20 million or more in assets.
Although the statutory marginal tax rates are often criticized as being very high, the average share of the estate paid in tax is much lower. Part of the reason for the lower effective tax rate is the exemption. For example, even if a $10 million estate has no other deductions and exemption, a $3.5 million exemption means only $6.5 million is taxed. The tax of $2.95 million (45% of $6.5 million) is a tax of 29.5% on the $10 million.
As shown in Table 6 , the effective tax averages less than 20% for estates up to $20 million and the average rate on those estates is less than 20%. The effective tax rate also rises, generally, with estate size, which would be expected as the exemption is a smaller share of the estate. With the $1 million exemption, the tax is 16.5% in the highest class, while it is 16% under the $3.5 million exemption and 11.5% under the $5 million exemptions. Important reasons for lower effective tax rates are the exemption, spousal transfers, and charitable contributions. The decline in effective tax rate at the very highest estate size for the $1 million exemption may reflect the greater likelihood of charitable contributions and the lesser importance of the exemption.
Most distributional analyses of taxes are reported relative to income. As shown in Table 7 , the Tax Policy Center has estimated the distribution by income class of the tax for the $1 million exemption/55% rate and the $3.5 million exemption/45% tax rate. As this table indicates, the estate tax is highly concentrated in the higher income classes. For the $1 million exemption, 83% of the tax falls in the top quintile and 45% of the tax in the top 1%. For the $3.5 million exemption, 96% of the tax is imposed on the top quintile and 72% on the top 1%. These results indicate that the estate tax is a highly progressive feature of the federal tax system.
section_title: Effects on Small Businesses and Farmers
paragraphs: An issue that has played an important role in the debate over the estate tax is the possible impact on small businesses and farms. The role played by the small business issue in the original 2001 legislation is detailed by Graetz and Shapiro. Arguments were made that the estate tax causes families to have to sell businesses to pay the estate tax because there are not enough liquid assets to pay the tax.
According to aggregate data for 2008, farm assets account for 2.4% of assets reported on estate tax returns, and business assets constitute 17.9%. These shares include assets of estates where business or farm assets may be a minor part of the estate.
Evidence on the effect of the tax on small business suggests that the taxable business estates are a small share of all taxable estates and a small share of estates of all business decedents. Table 8 provides estimates for the coverage of the estate tax reported or derived from the Urban Brookings Tax Policy Center of estates with at least half of their assets in business. As shown in the table, these estates are less than 10% of taxable estates, and, as with other estates, only a small fraction of business estates pay the estate tax (0.2% for the $3.5 million and $5 million exemption).
As shown in Table 9 , data indicate that returns with business assets account for a somewhat higher share of the estate tax than they do of the number of taxable estates, suggesting some larger concentration of business assets in larger estates. (Note that in this case, the tax paid reflects total estate tax, and thus includes tax on business and non-business assets.) However, the effective tax rates (taxes paid as a percentage of the assets of all estates of $1 million or more) are somewhat lower for these small business returns, suggesting the use of discounts may be important.
Although the Urban Brookings Tax Policy Center did not separately estimate farmer estates or consider questions of whether these estates had adequate liquid assets to pay the tax, a study done by the Congressional Budget Office (CBO) did examine these issues. This CBO study likely defined farmers more broadly than the Tax Policy Center criterion. At the same time, it examined the subset of estates that took the QFOBI exemption, which would be both small business and farm estates where the heirs expected to continue the business and where more than half of the estate was in the family business. The analysis was for 2000. Column 2 of Table 10 reports those values at an average annual growth rate of 3.5% for 11 years (for 2000 to 2011), to project the distribution across estate sizes for 2011. (This measure increases the value by the average annual growth rate of the economy minus growth in the labor force for 2000-2009, applied over 11 years, thus taking into account real wealth growth as well as inflation.)
 Table 10 indicates that the number of farm estates, using their measure of farms subject to the tax, would be less than 123 estates at the $3.5 million exemption and about 65 at the $5 million exemption. These estates are about 2% of all estates owing tax. The number of returns claiming QFOBI are also small, accounting for 2% to 2.5% of all taxable estate returns.
 Table 11 shows results the study found for a second question: how many estates of these types are likely to have insufficient liquid assets in the estate to pay the tax liability? While there were 138 farm estates in these circumstances for the $1 million exemption, there were only about 15 for the larger exemptions. These returns account for 0.2% and 0.4% of returns paying estate tax. For estates claiming the QFOBI deduction there were 62 at the $3.5 million exemption and 41 at the $5 million exemption. These returns accounted for about 1% of taxable estates.
A different survey of farmers performed by the Department of Agriculture estimated that farm estates would pay $683 million in estate taxes in 2009, which would be just under 4% of total estate tax liability, and that 1.6% of farms decedents would pay the estate tax under the 2009 provisions. This share is much larger than the share for businesses overall reported by the Tax Policy Center and is also about twice as large as the estimates implied by the CBO study.
Regardless of the data source used, the evidence suggests two important characteristics of businesses and the estate tax: businesses pay a small fraction of the estate tax and a tiny fraction of total estates of businesses and farmers are liable for the tax. If estate tax policy decisions are driven by these concerns, a more target-efficient alternative would be to provide additional benefits for business assets, such as an expanded QFOBI deduction.
section_title: Effects on Savings and Output
paragraphs: Some claims have been made that the estate tax causes a significant reduction in savings. This effect may be alleged to be so damaging that it justifies eliminating the tax. However, there is no clear basis for this claim. Economic theory does not provide a clear guide. If the bequest motive is primarily to leave a bequest to one's heirs because of concerns about their welfare, the estate tax could lead to less saving (because a gift to one's children is made more costly relative to one's own consumption, the substitution effect), or it could lead to more savings to retain a larger amount after the estate tax is paid (the income effect). These offsetting income and substitution effects create an ambiguous theoretical prediction about the effect of the estate tax on savings. If the main purpose of accumulating assets is to provide a precautionary savings amount (to account for catastrophic illness, for example), the estate tax does not matter, since it is irrelevant to that purpose.
With theoretical uncertainty, the issue becomes an empirical one. Here, however, there is virtually no empirical evidence. In the single study of the wealth elasticity of estates (the percentage change in wealth divided by the percentage change in taxes), Kopczuk and Slemrod characterized their results as fragile, meaning that the results depended on model specification.
A study by Holtz-Eakin and Smith used an elasticity from one of the specifications in the Kopczuk and Slemrod study to estimate that the estate tax caused a decrease in wealth of $1.6 trillion. Although this estimate was based on total projected wealth associated with those filing estate tax returns (in 2004), the report indicated the increase in capital was an increase in small business capital (although, as noted above small businesses account for only a fraction, about 16%, of the estate tax). That estimate was, in turn, used to project increases in hiring by small businesses.
The effect projected in the Holtz-Eakin and Smith study appears quite large. As a simple illustration, consider that the effect of estate taxes on savings should be similar to the effect of capital income taxes in general. In 2007, the last year for which data on sources of income in the income tax were available, the estate tax accounted for only 4% of capital income tax revenue at the Federal level. This ratio implies that eliminating capital income taxes would increase wealth by $40 trillion ($1.6 trillion dividend by 0.04). This amount would be an approximate doubling of the total U.S. capital stock. Even the most generous model with infinitely elastic savings responses tends to produce an increase of about one-third that size, and estimates based on the higher end of empirically estimated time-series savings rates would suggest a result only one-tenth of that size. Some effects from dynamic models, depending on how the revenue loss is offset, are negative or negligible.
One problem with the estimate in the estate tax study is that it did not take account of feedback effects from the economy, particularly the decline in pre-tax return when the capital stock expands. That feedback effect is the reason that an infinitely elastic response leads to a limited effect: the capital stock expands only enough to drive the after tax return back to its original value.
Given lack of theoretical and empirical evidence it is not possible to precisely determine what the effect of repealing the estate tax on savings, but it is likely to be small, simply because the yield of the tax is small. Any effect on the stock of capital in small business should only be a fraction of that amount.
The tax rate is more important than the exemption in determining any positive effects of reducing the estate tax on savings, since that rate is more important for the marginal rate that drives the substitution effect. Exemptions affect the substitution effect by pushing some income into a zero marginal tax rate, but are more important for the average rates that determine the income effect, so that higher exemptions are less likely to increase savings than higher rates.
section_title: Effect on Charitable Contributions
paragraphs: Unlike the effect of the estate tax on savings, there is an extensive empirical literature on the response of charitable bequests in the estate tax, and the evidence indicates a significant response of bequests. Nevertheless, according to a recent CRS study, the effect on overall charitable giving is likely to be small: moving from the $1 million exemption with a 55% tax rate to the $3.5 million exemption with a 45% tax rate would be projected to lower charitable giving by 1%; moving to the $5 million exemption with a 35% rate would be projected to reduce giving by 2%. These relatively small effects occur largely because only 4% to 6% of giving is affected by the estate tax. The effects would be larger for foundations and certain types of organizations (such as higher education) that are more likely to receive bequests.
section_title: Administrative and Compliance Cost
paragraphs: Another issue is the degree to which the estate tax causes excessive compliance and planning costs for taxpayers, and administrative costs for the IRS. Some arguments have been made that these costs, particularly for estate planning, are as large as the estate tax itself. Gale and Slemrod, however, review the limited evidence and conclude that the cost of administration and compliance is probably in the neighborhood of 7% of revenues, with almost all of that cost due to planning and compliance.
section_title: Other Design Issues
paragraphs: This section briefly discusses proposals to revise certain features of the estate tax. These include portability of the spousal exemption, changing the rules on certain trusts, restricting minority discounts, and conforming definitions of fair market value for estates and heirs.
subsections: section_title: Portability of the Spousal Exemption
paragraphs: Because transfers between spouses are exempt from the estate tax, the estate exemption is of no value to a person who transfers all of his or her estate to a spouse. For example, if the estate tax exemption is $3.5 million and a couple jointly owns assets of $8 million ($4 million each), if the first spouse to die leaves $4 million to the second spouse, and the second spouse then leaves $8 million to children, $4.5 million of the estate will be subject to tax. If the first spouse to die left $3.5 million to the children directly, then the second spouse would have an estate of $4.5 million, with only $1 million subject to the estate tax.
There are estate planning options (such as credit shelter trusts) that can address this issue. However, these options (which may also require an initial transfer of assets between spouses) not only require complicated estate tax planning but also may cause taxpayers to dispose of their assets in a way that they would not prefer.
Simply allowing a spouse to inherit any unused portion of the exemption is an alternative. In the example above, all of the assets could be left to the remaining spouse on the death of the first spouse, and the second spouse to die would be able to claim a total exemption of $7 million (the sum of both exemptions). Portability can also be valuable with assets, such as pension rights, that cannot be transferred. This portability feature has been adopted for the extension of the estate tax for 2011 and 2012.
Although there are some advantages to this provision in both equity and simplified planning, there are problems as well. First, the portability provision, if made permanent, will cost increasing amounts of revenue in the future. The JCT provided estimates suggesting that the number of estates benefitting from portability will increase by 14 times over 10 years. Thus, allowing portability is likely to substantially decrease revenues in the long run. However, it may be more likely to benefit smaller estates where it may be more difficult to engage in the types of transfers and planning needed to absorb the credits.
There are some complications as well for designing and administering this provision, some of which are detailed in the JCT study. Second (and more) marriages raise an issue. Should the inheritance be allowed for future marriages or should it be inherited only once? That is, suppose a widow remarries, and then dies leaving all her assets to a second spouse: does the second spouse inherit two exemptions or one? Is there a possibility for deathbed marriages to terminally ill low income individuals to generate an additional deduction (and how can that be distinguished from "legitimate" marriages with a tragic early death)? 
The 2011 provision allows multiple inheritances but limits the exclusion to the last predeceased spouse, which affects total exclusions available in second marriages depending on the order of death. Thus if a wife's husband number two dies first, she gets the smaller of the exemptions from husband one and husband two, whereas if the wife dies first, husband number two gets all unused exemptions, whether they are his wife's own exemptions or inherited from husband number one.
Another question is: should the value of the inherited exemption be limited to the value of the spouse's estate? That seems to be a reasonable rule. Otherwise, if the second spouse continues to accumulate wealth, the portability would effectively increase the exemption over the amount available had each spouse absorbed the exemption in their own estate. Such a rule, however, would require the filing of estate tax returns and valuation of the estate when they would not otherwise be subject to tax. There would also be issues about how to reconstruct fair market value, if the portability were allowed if the first estate tax return were not filed. As with many solutions that seem simple, complications remain. The 2011 -2012 provision allows the exemption to exceed the value of the estate, but requires a declaration be made on the estate return for the exemption to be transferred. Thus, presumably those who do not file an estate return because they are below the filing threshold or otherwise make a declaration will not benefit from the portability rule. 
section_title: Grantor Retained Annuity Trusts
paragraphs: A Grantor Retained Annuity Trust (GRAT) is a trust that allows the grantor to receive an annuity, with any remaining assets transferred to the trust recipient. The value of the gift is reduced by the value of the assets used to fund the annuity. If the assets in the trust appreciate substantially, then virtually all of the gift can be reduced by the value of the annuity, while still providing a substantial ultimate gift to the recipient. If the grantor dies during the annuity period the remaining value of the annuity is included in the estate. Thus for this trust approach to be a method of transferring assets roughly tax free, the assets must appreciate at a rate faster than the discount rate used to value the annuity, and the grantor needs to survive over the period of the annuity. To assure the latter will be likely to occur, many of these trusts have very short annuity periods, as short as two years. The GRAT proposal contained in H.R. 4849 and in the President's budget proposals would impose a minimum annuity term of 10 years, disallow any decline in the annuity, and require a non-zero remainder interest. The Administration estimates this proposal would raise $3 billion over 10 years.
section_title: Minority Discounts
paragraphs: There are existing restrictions to keep estates from engaging in artificial actions designed to reduce the value of estates (such as freezes on assets). As discussed above, courts sometimes allow estates to reduce the fair market value when assets are left in family partnerships where no one has a majority control. These discounts have even been allowed when assets are in cash and readily marketable securities, and the setting up of these family partnerships has become an estate tax avoidance tool. A provision in the Administration's proposal would set up a category of disregarded actions that could not be used to allow discounts. The estimated revenue gain is $18.7 billion over 10 years.
section_title: Consistent Valuation
paragraphs: There is no explicit rule preventing a low valuation of fair market value for an estate and a high valuation of the asset for purposes of stepped up basis in the hands of the heir. A provision in the Administration's budget proposals would require this value to be the same and is projected to raise $3 billion over 10 years.
section_title: Conclusion
paragraphs: The analysis indicates that the estate tax is relatively small, in revenues, in coverage, and in its effects on family businesses, savings, charitable contributions, and tax administration and compliance. One-fourth of 1% or less of all estates and of family businesses are expected to be subject to tax under an exemption of $3.5 million or $5 million. This share would grow slightly over the 10-year budget horizon, but indexing the exemption would not be very important over this short time period.
The estate tax is a small, but highly progressive, element of the tax system. Under the proposals under consideration (the $3.5 million exemption and the $5 million exemption), the majority of the tax falls on estates of $20 million or more, which in turn constitute only three-hundredths of 1% of decedents. For the $3.5 million exemption, 45% rate effective in 2009, 96% of the tax falls on the top quintile of the income distribution, 72% falls in the top 1%, and 42% in the top 0.1%.
Effects on savings are uncertain in direction but likely small. Based on empirical evidence, a decline of 1% to 2% in charitable contributions from increasing the estate tax relative to the current law baseline of a $1 million exemption with a 55% rate would be expected. Costs of estate planning and administration are relatively small as a percentage of estate tax revenue.
Because transfers between spouses are exempt, allowing spouses to inherit the exemption can increase the combined couples' exemption, and simplify estate planning. This change could cost increasing amounts of revenue over time, however, and lead to certain administrative complications.
Several provisions to deal with perceived abuses might be considered, with the most important one relating to the use of discounts when assets are left to a family partnership and no one heir controls the property.
