Analysis of the Tax Exclusion for Canceled Mortgage Debt Income

Summary
A home foreclosure, mortgage default, or mortgage modification can have important tax
consequences. As lenders and borrowers work to resolve indebtedness issues, some transactions
are resulting in cancellation of debt. Mortgage debt cancellation can occur when lenders
restructure loans, reducing principal balances, or sell properties, either in advance, or as a result,
of foreclosure proceedings. Historically, if a lender forgives or cancels such debt, tax law has
treated it as cancellation of debt (COD) income subject to tax. Exceptions have been available for
taxpayers who are insolvent or in bankruptcy, among others—these taxpayers may exclude
canceled mortgage debt income under existing law.
The Mortgage Forgiveness Debt Relief Act of 2007 (P.L. 110-142) signed into law on December
20, 2007, temporarily excluded qualified COD income. Thus, the act allowed taxpayers who did
not qualify for the existing exceptions to exclude COD income. The provision was effective for
debt discharged before January 1, 2010. The Emergency Economic Stabilization Act of 2008 (P.L.
110-343) extended the exclusion of COD income to debt discharged before January 1, 2013. The
American Taxpayer Relief Act of 2012 (P.L. 112-240) subsequently extended the exclusion
through the end of 2013. Most recently, the Tax Increase Prevention Act of 2014 (P.L. 113-295)
retroactively extended the exclusion through the end of 2014. In the 114th Congress, H.R. 1002
and S. 1946 would extend the exclusion two years through the end of 2016, while H.R. 2166
would permanently extend the exclusion.
A rationale for excluding canceled mortgage debt income has focused on minimizing hardship for
households in distress. Policymakers have expressed concern that households experiencing
hardship and that are in danger of losing their home, presumably as a result of financial distress,
should not incur an additional hardship by being taxed on canceled debt income. Some analysts
have also drawn a connection between minimizing hardship for individuals and consumer
spending; reductions in consumer spending, if significant, can lead to recession.
As efforts to minimize the rate of foreclosure are being made, lenders are, in some cases,
renegotiating loans with borrowers to keep them in the home. For some policymakers, the
exclusion of canceled mortgage debt income may be a necessary step to ensure that homeowner
retention efforts are not thwarted by tax policy.
Opponents of an exclusion for canceled mortgage debt income might argue that the provision
would make debt forgiveness more attractive for homeowners, and could encourage homeowners
to be less responsible about fulfilling debt obligations.
This report will be updated in the event of significant legislative changes.

Analysis of the Tax Exclusion for Canceled Mortgage Debt Income

ortgage debt cancellation occurs when lenders engage in loss-mitigation solutions that
either (1) restructure the loan and reduce the principal balance or (2) sell the property,
M either in advance, or as a result of foreclosure proceedings.1 Under current law, the
canceled debt (sometimes referred to as discharge of indebtedness) may be income subject to
taxation.
The Mortgage Forgiveness Debt Relief Act of 2007 (P.L. 110-142) signed into law on December
20, 2007, temporarily excluded qualified “cancellation of debt” or COD income. Thus, the act
allowed taxpayers who did not qualify for the existing exceptions to exclude COD income. The
provision was effective for debt discharged before January 1, 2010. The Emergency Economic
Stabilization Act of 2008 (P.L. 110-343) extended the exclusion of COD income to debt
discharged before January 1, 2013. The American Taxpayer Relief Act of 2012 (P.L. 112-240)
subsequently extended the exclusion through the end of 2013. Most recently, the Tax Increase
Prevention Act of 2014 (P.L. 113-295) retroactively extended the exclusion through the end of
2014. In the 114th Congress, H.R. 1002 and S. 1946 would extend the exclusion two years
through the end of 2016, while H.R. 2166 would make the exclusion permanent.
The rationales for this change are to minimize hardship for households in distress and to ensure
that non-tax-related homeowner retention efforts are not thwarted by tax policy. Critics argue that
the exclusion could encourage homeowners to be less responsible about fulfilling debt
obligations.2 Critics may also argue that owner-occupied housing is sufficiently subsidized even
without a COD income exclusion.
This report begins with an overview and analysis of the historical tax treatment of canceled debt
income. Next, the changes enacted by P.L. 110-142, P.L. 110-343, P.L. 112-240, and P.L. 113-295
are discussed. A discussion of policy options concludes.
Overview
For federal income tax purposes, there are two types of income that may arise when an
individual’s mortgage is fully or partially canceled: cancellation of indebtedness income and gain
from the disposition of property.
Cancellation of Indebtedness Income
When all or part of a taxpayer’s debt is forgiven, the amount of the canceled debt is ordinarily
included in the taxpayer’s gross income.3 This income is typically referred to as cancellation of
debt (COD) income. The borrower will realize ordinary income to the extent the canceled debt
exceeds the value of any cash or property given to the lender in exchange for cancelling the debt.

1 In order to avoid foreclosure proceedings, lenders and homeowners may agree to “short sell” properties or “deed-in-
lieu” transactions. In short sales, the property is listed for sale with the lender agreeing to take a reduced payoff on the
outstanding loan amount. If the property cannot easily be sold, the homeowner may give the lender the deed to the
property in lieu of foreclosure proceedings. The benefit of either option is that the homeowner does not suffer the
adverse credit impacts and possible stigma of foreclosure and the lender can clear a non-performing loan without the
associated costs of foreclosure, eviction, and property rehabilitation.

Analysis of the Tax Exclusion for Canceled Mortgage Debt Income

Lenders report canceled debt to the Internal Revenue Service (IRS) using Form 1099-C, and
borrowers must generally include the amount in gross income in the year of discharge.
Exceptions
Historically, there have been several exceptions to the general rule that canceled debt is included
in the gross income of the borrower. Section 108 of the Internal Revenue Code (IRC) contains
two exceptions that are particularly relevant in the case of canceled home mortgage debt: a
borrower may exclude canceled debt from gross income if (1) the debt is discharged in Title 11
bankruptcy or (2) the borrower is insolvent (that is, has liabilities that exceed the fair market
value of his or her assets, determined immediately prior to discharge).4
In the case of the bankruptcy exception, the debt must be discharged by the court overseeing the
bankruptcy proceedings or pursuant to a plan approved by that court.5 No involvement by a court
is necessary for a taxpayer to claim an insolvency exception—the taxpayer calculates his or her
assets and liabilities to determine whether he or she is insolvent. For an insolvent taxpayer, the
amount of COD income that may be excluded is limited to the amount by which the taxpayer is
insolvent.6
For both the bankruptcy and insolvency exceptions, a taxpayer who excludes canceled debt must
essentially give back some of the benefit of the exclusion. Specifically, the taxpayer must reduce
certain beneficial tax attributes, including basis in property, that would otherwise decrease the
taxpayer’s income or tax liability in future years.7 The attributes are reduced until the reductions
generally account for the excluded amount. As a result of the attribute reduction, the taxpayer
may be subject to tax on the excluded COD income in years following the year of discharge—in
other words, the tax on the COD income is deferred.
In addition to the IRC §108 exclusions, there are several other circumstances under which COD
income may be excluded. For example, a taxpayer with nonrecourse, as opposed to recourse,
debt8 will not realize COD income.9 Other examples of when COD income may be excluded from
the borrower’s income are if the cancellation was intended to be a gift10 or was the result of a
disputed debt.11
Gain From the Disposition of Property
When an individual sells property, the excess of the sales price over the original cost plus
improvements (adjusted basis) is normally gain subject to tax.12 If the property was held for more

5 See IRC §108(d)(2).
6 See IRC §108(a)(3).
7 See IRC §108(b). The taxpayer reduces basis in property in the order set out by Treasury Regulation §1.1017-1. Basis
reduction occurs in the taxable year following the debt discharge. See IRC §1017(a).
8 Recourse debt is debt for which the borrower is personally liable if he or she defaults on the loan. Nonrecourse debt is
secured by property, and the borrower is not personally liable for the debt; if he or she defaults on the loan, the lender’s
only remedy is to seize the property.

than 12 months, the gain is taxed at a maximum rate of 15% rather than regular income tax rates.
If the property was held for less than 12 months, the gain is taxed at regular income tax rates.
In situations involving canceled home mortgage debt, if the lender takes the home in exchange for
the debt cancellation, the homeowner realizes gain from the disposition of property in the amount
that the property’s fair market value (or the amount of outstanding debt, in the case of
nonrecourse debt) exceeds the taxpayer’s adjusted basis in the property.13 A taxpayer may have
both gain from the disposition of property and COD income.
IRC §121 provides an exclusion for gain from the sale or disposition of a personal residence. The
provision excludes gain of up to $250,000 for single taxpayers and $500,000 for married couples
filing joint returns if the taxpayer meets a use test (has used the house as the principal residence
for at least two of the last five years) and an ownership test (has owned the house for at least two
of the last five years). A taxpayer who does not meet the qualifications may be eligible for a
partial exclusion if the home was sold because of a change in employment or health or due to
unforeseen circumstances.14 Additionally, other taxpayers may qualify for special treatment (e.g.,
members of the Armed Forces).15 The exclusion can generally be used every two years.
Legislative Developments
On December 20, 2007, The Mortgage Forgiveness Debt Relief Act of 2007 (P.L. 110-142) was
signed into law. The act, among other things, excluded discharged qualified residential debt from
gross income. Qualified indebtedness is defined as debt, limited to $2 million ($1 million if
married filing separately), incurred in acquiring, constructing, or substantially improving the
taxpayer’s principal residence that is secured by such residence. It also includes refinancing of
this debt, to the extent that the refinancing does not exceed the amount of refinanced
indebtedness. The taxpayer was required to reduce the basis in their principal residence by the
amount of the excluded income. The provision did not apply if the discharge was on account of
services performed for the lender or any other factor not directly related to a decline in the
residence’s value or to the taxpayer’s financial condition. The provision applied to debt
discharges that are made on or after January 1, 2007, and before January 1, 2010.
The Emergency Economic Stabilization Act of 2008 (P.L. 110-343) extended the exclusion
described above through the end of 2012. Subsequently, the American Taxpayer Relief Act of
2012 (P.L. 112-240) extended the exclusion through the end of 2013. Most recently, the Tax
Increase Prevention Act of 2014 (P.L. 113-295) retroactively extended the exclusion through the
end of 2014. In the 114th Congress, H.R. 1002 and S. 1946 would extend the exclusion two years
through the end of 2016, while H.R. 2166 would make the exclusion permanent.

Analysis
In order to evaluate the policy of including discharged debt as income, it is helpful to understand
why it exists. According to economic theory, one way of defining income is as the change (over

the period in question) in a person’s net worth—that is, the change in the value of the person’s
assets minus the change in their liabilities. By this definition, a forgiven loan is income: a
canceled debt reduces a taxpayer’s liabilities, and thus increases net worth. In the past, tax law
has generally adhered to this concept by providing that if the obligation to repay the lender is
forgiven, the amount of loan proceeds that is forgiven is reportable income subject to tax.16
This portion of the report provides analysis of the issues associated with the tax treatment of
canceled mortgage debt income.
Homeownership Retention or Loss
In some instances, lenders may restructure or rearrange debt, cancel some debt, and allow the
homeowner to retain ownership of the home. Then, all other things being equal, the borrower’s
net worth has increased as liabilities have declined and assets have remained unchanged.
Alternatively, homeowners may experience debt cancellation while losing their home, through
foreclosure or as a result of voluntarily deeding the property back to the lender. The homeowner
no longer has the asset and, to the extent the asset value exceeded liabilities, may be worse off as
a result of declining net worth. Additionally, he or she may realize gains or losses, which may
make the taxpayer better or worse off as well.
If the taxpayer is not able to exclude the COD income, then the tax consequences of the COD
income, assuming equal amounts of canceled debt, are the same regardless of whether the home
is retained or lost.
An illustration is shown in Table 1. Assuming residential debt of $200,000, a loan restructuring
could occur, after which the homeowner owes $180,000 and the lender has agreed to cancel the
remaining amount. The discharged debt, $20,000, is income subject to tax if no exclusion applies
(e.g., the taxpayer is not insolvent)—if a rate of 28% is assumed, the tax liability is $5,600.
Alternatively, the home could have been sold as a result of foreclosure with a sales price of
$180,000 along with a lender agreement to cancel the remaining debt. The $20,000 discharge is
income and, assuming no exclusion applies and the same tax rate, generates the same tax liability.
This is in addition to any taxes the taxpayer may owe on the gain from the sale of the house.

On the other hand, if the taxpayer is able to exclude the COD income, as is temporarily allowed
in certain circumstances, then the $20,000 discharge is not included in gross income and the
taxpayer does not owe the $5,600 tax liability. As previously mentioned, current law stipulates
that the excluded COD income be accounted for through reducing the basis in the residence.

16 This tax treatment applies to many different kinds of debt, such as auto loans and credit cards, in addition to
mortgage debt. As mentioned previously, if taxpayers are insolvent or bankrupt, they are fully or partially exempt from
taxation on the canceled debt.

The impact of such basis adjustment could differ, depending on whether the home is retained or
lost, if the taxpayer owes taxes when the house is disposed. A taxpayer who retains the house and
sells a later year, while accounting for the excluded COD income through basis adjustment,
defers taxes owed on the disposition until the year of sale.
In contrast, the tax consequences would depend on the timing of the basis adjustment for a
taxpayer that loses a home. If basis is reduced in the year following discharge, as under IRC
§1017, then the excluded COD income could not be accounted for because the taxpayer had
already disposed of the home. If basis was required to be reduced earlier (e.g., at the time of
discharge), then the excluded COD income would be accounted for through basis adjustment and
the taxpayer would be worse off than a similarly situated taxpayer who had retained the house
and was able to defer taxes until the year of sale.17
Equity Among Homeowners
An exclusion of certain types of income can result in individuals with identical incomes paying
different amounts of tax. A standard of fairness frequently invoked by public finance analysts in
evaluating tax policy is “horizontal equity”—a standard that is met when similarly situated tax
units pay the same amount of tax. Like other exclusions, excluding debt forgiveness, a unique
type of income, violates the standard of horizontal equity.
An exclusion of income can also reduce the tax system’s progressivity—in other words, likely
favor upper-income individuals. This is likely to occur because an exclusion of a given amount is
more valuable to persons with higher marginal tax rates. This effect is magnified if
homeownership is more concentrated among upper income individuals.
At this point, an example may be useful for illustrating the effect income tax exclusions can have
on the tax system’s progressivity. Consider two individual homeowners, both of whom incur
$20,000 in COD income. The tax benefit differs when the taxpayers are in different tax
brackets.18 The value of the exclusion for a homeowner with lower income, who may be in the
15% income tax bracket, is $3,000, while the value to another homeowner, with higher income
and thus in the higher 28% bracket, is $5,600. The higher income taxpayer, with presumably
greater ability to pay taxes, receives a greater tax benefit than the lower income taxpayer.
Congress has provided an exclusion for COD income several times in the past, though the
economic and political circumstances for relief were not the same in each case. For example, in
1986 and again in 1993, relief was provided for commercial property owners and farmers, and in
2005, for victims of Hurricane Katrina. The residential housing crisis of 2007 and subsequent
recession initiated the most recent legislative action.
Data
Lenders report canceled debt income to the IRS on Form 1099-C. A copy is also sent to the
borrower who reports the amount as income. Form 1099-C is used to report all types of canceled
debt, not just residential. As shown in Table 2, the number of 1099-C forms filed rose by 284%
from 2007 through 2013. The amount of canceled debt also increased during this time period,
from $1.9 billion to $10.0 billion, although canceled debt peaked in 2011 at $13.8 billion. While

17 The time value of money asserts that the present value of a certain amount of money is greater than the future value
of that same amount. Thus, the cost of a tax payment of $5,600 today is more than the same amount paid in the future.
18 COD income may cause a taxpayer to move to a higher tax bracket.

specific conclusions about mortgage debt cancellation cannot be drawn from these data, to the
extent that debt cancellation represents financial distress, the data suggest that the number of
financially distressed taxpayers increased during the recession and has remained elevated.

Policy Options
The changes enacted by P.L. 110-149 and then extended by P.L. 110-343, P.L. 112-240, and P.L.
113-295 were temporary and expired at the end of 2014. Congress may choose to allow the
changes to remain expired, thus subjecting canceled mortgage debt income to its traditional tax
treatment. Under current law, canceled debt income would be subject to taxation unless the
taxpayer meets a qualified exception (e.g., the taxpayer is insolvent). If the exclusion on canceled
debt income remains expired, improving awareness about the existing exclusions for canceled
debt, such as for insolvency or bankruptcy, may be an option to pursue. Congress may choose to
extend the exclusion of canceled debt income possibly with some modifications. Which
modifications, if any, are enacted will depend on the goal of policymakers.
Temporary vs. Permanent Exclusion
One consideration for Congress is whether an exclusion provision should be temporary or
permanent. Some argue that recent housing market conditions are temporary (and improving),
and therefore warrant a temporary solution. A temporary exclusion of canceled debt income
would appear to be consistent with a policy of minimizing adverse consequence associated with
loan renegotiations in the short-term.
It could also be argued that the temporary exclusion of residential COD income is preferable
because owner-occupied housing is already heavily subsidized even without a COD exclusion.
Three principal tax provisions for owner-occupied housing currently exist in the tax code: the
deduction for mortgage interest, the exclusion of gain on the sales of homes, and the deduction of
state and local real estate taxes. When combined these three provisions result in over $100 billion
in reduced federal revenue annually.19 Some economists feel that this preferential tax treatment

Analysis of the Tax Exclusion for Canceled Mortgage Debt Income

encourages households to overinvest in housing and less in business investments that might
contribute more to increasing the nation’s productivity and output.20
On the other hand, some analysts might argue that the provision should be permanent. A case
could be made that a temporary provision is unfair because there is no difference between an
individual experiencing canceled debt income in 2015, when foreclosure rates may be relatively
high compared to three or four years from now, when foreclosure rates may be lower. If the intent
is to minimize hardship when taxpayers experience distress, then making the provision permanent
would seem consistent with that objective.
Modify Definition of Debt Eligible for Cancellation
Several options are possible for determining in what situations canceled mortgage debt income
may be excluded from taxation. The broadest modification would exclude all canceled residential
debt from income. Currently, only debt associated with the primary (or principal) residence of a
taxpayer may be excluded and not vacation homes or investment property.21
Some policy analysts have suggested disallowing second liens as qualified residential debt.
Second liens are not directly ineligible for the exclusion, although currently, qualified debt is
restricted to include debt incurred in acquiring, constructing, or substantially improving the
taxpayer’s principal residence.
For some individuals, second liens may be home equity lines of credit, for others, second liens
may be debt incurred as part of the purchase of the home. To the extent that home equity lines of
credit are used to enhance the home and make capital improvements, it may be consistent with
stated policy goals to include this debt as eligible for the exclusion. Yet, home equity lines of
credit can also be used to finance consumption, such as vacations or paying off other debt. It may
not be consistent with the stated policy goals, some might argue, to include this type of debt in the
exclusion.
Congress may also wish to consider changing the limit on the amount of canceled debt that can be
excluded from income. P.L. 110-142 imposed a limit of $2 million ($1 million if married filing
separate returns). Increasing the limit would likely increase revenue loss associated with the
exclusion, while decreasing the limit would have the opposite effect. Decreasing the exclusion
limit might also reduce the benefit to upper income taxpayers.
Modify Homeowner Eligibility
Policymakers could modify homeowner eligibility requirements based on ownership tenure or
income.
Ownership Tenure
The exclusion for canceled debt income could be limited to homeowners who meet certain
ownership and/or use tests similar to other housing related tax provisions. For example, a
homeowner must meet both an ownership and use test in order to claim the exclusion for gain on
owner-occupied housing that is available under IRC §121. The ownership test requires the

21 H.R. 1876/S. 1394 (110th Congress) would have limited the exclusion to the residence of the taxpayer, but not the
principal residence; H.R. 3506 (110th Congress) limits the exclusion to the principal residence.

taxpayer to have owned the house for two of the last five years, while the use test requires the
owner to have lived in the house for at least two years out of the last five years. Limiting the
exclusion of capital gains in this manner was designed to minimize the possibility that investors,
rather than owner-occupants, would exclude capital gains from taxation.
If an ownership and/or use test were applied to an exclusion of COD income, the number of tax
filers eligible to claim the exclusion might be reduced. This reduction in filers may result in lower
revenue loss. This policy option would add complexity to the reporting and filing processes and
thus the tax code. In addition, it could be argued that tenure is not relevant to the stated policy
goals of mortgage debt cancellation.
Household Income
Some policymakers have suggested that foreclosure assistance be provided only to households
with low and moderate incomes.22 As with other housing tax incentives, such as the mortgage
revenue bond program and the first-time homebuyer tax credit for District of Columbia residents,
income levels could be capped and the exclusion made unavailable to those households with
income above the ceiling. It would seem that income and foreclosure would be highly correlated
because lower income taxpayers may be more financially constrained than higher-income
taxpayers. Regardless of whether this is true, it could be argued that household income is not
relevant to the stated policy goals for the legislation.
This option could reduce the revenue loss associated with the provision, but would add
complexity to the administration and tax filing process.
Should Basis Be Adjusted?
As discussed above, current law requires that taxpayers who exclude COD income must “return”
some tax benefit by reducing other tax attributes, such as basis in property. Several policy issues
arise from this rule. The first is which tax attributes, if any, should be adjusted to account for
excluded canceled mortgage debt income. One option is that there be no “attribute reduction”
requirement. Alternatively, homeowners could be required to reduce specified tax attributes that
include, but are not limited to, basis in the residence (e.g., taxpayers would be able to reduce basis
in property other than the home subject to the discharged mortgage). A third option would be to
require basis reduction in the taxpayer’s residence. All taxpayers would benefit from the first
option by not accounting for the excluded COD income. Taxpayer preference between the second
option and the third option would depend on his or her circumstances (e.g., whether the taxpayer
has basis in other property that would have to be reduced in the event of insufficient basis in the
residence). The temporary exclusion of COD income enacted by P.L. 110-142 uses the third
option—homeowners are required to reduce basis in the principal residence to account for the
excluded COD income.
Another issue is when tax attributes should be adjusted. If basis is adjusted, one option could be
to make the proposal consistent with current law, under which basis adjustment occurs in the year
following discharge of the debt. Alternatively, basis adjustment could occur earlier (e.g., at the
time of discharge or exclusion). If basis adjustment occurred in the year after discharge,
homeowners losing their home at the time of debt cancellation would have already disposed of
the property.

22 H.R. 3506 (110th Congress) proposed a limit of $100,000 for the household income of eligible taxpayers ($200,000
for married taxpayers filing jointly).
Congressional Research Service

Analysis of the Tax Exclusion for Canceled Mortgage Debt Income

The requirement that a basis adjustment in the amount of cancelled debt suggests a desire by
policymakers for homeowners to account for the benefit of the cancelled debt. Basis adjustment
results in the taxation of cancelled debt income to the extent that gain from the disposition of the
home is taxable; however, the timing of the basis adjustment may result in different tax
consequences for taxpayers who lose their home.
The exclusion of COD income may result in differential treatment of taxpayers depending on
basis adjustment timing, eligibility for exclusion of gain from the disposition of the residence, and
homeownership retention. Policymakers may wish to account for that differential treatment,
