Section 36 of the Internal Revenue Code (IRC) provides for a credit for many taxpayers who bought a principal residence in 2008, 2009, or 2010. The amounts of the credit vary depending upon whether the property was purchased in 2008 or was purchased later and, for purchases made after 2008, whether the purchaser qualified for the "long-time resident" exception. Credits based on purchases made in 2008 generally must be repaid over a 15-year period. Those for subsequent years' purchases generally are not subject to repayment. However, Section 36(f)(2) provides for acceleration of the repayment in certain circumstances if the taxpayer ceases to use the property as a principal residence. For credits based on purchases after 2008, acceleration of repayment means that the entire credit must be repaid if taxpayers cease using the purchased properties as their principal residences within the 36 months following the purchase. For credits based on a 2008 purchase, acceleration of repayment means that the outstanding balance of the credit becomes due. In each case, the repayment is calculated and included as tax on the tax return for the tax year in which the property ceased to be the taxpayer's principal residence. There are several exceptions to these repayment provisions. This report addresses the exception for involuntary conversions of the property, as well as the limitation on repayment based on gain (if any) realized on the disposition of the property as it applies to involuntary conversions. Generally, an involuntary conversion will not trigger acceleration of repayment in the tax year in which the involuntary conversion occurs. Under the exception for involuntary conversions, taxpayers who have received the homebuyer tax credit have two years from the date of the involuntary conversion to replace the property and, thereby, avoid acceleration of repayment. For those who purchased their homes in 2008, the involuntary conversion will not suspend their existing duty to repay the credit over a 15-year period. Those who purchased property in 2008 and received the maximum $7,500 credit were required to begin repayment of the credit at $500 per year beginning with their 2010 tax returns. If the property was destroyed or otherwise involuntarily converted in 2011, they still would be required to repay $500 on their 2011 and 2012 tax returns. Only acceleration of repayment is affected by an involuntary conversion. Although the acceleration provision is not triggered in the year of the involuntary conversion, the involuntary conversion must nonetheless be reported to the Internal Revenue Service (IRS) on the tax return for the year in which the involuntary conversion occurs. This is done on Form 5405. The form requires taxpayers to report any disposition or change in the use of the property on which the credit was based. On the 2010 Form 5405, two options apply to involuntary conversions. The first (line 13f) states, "My home was destroyed, condemned, or disposed of under threat of condemnation and I acquired or plan to acquire a new home within 2 years of the event (see instructions)." The second (line 13g) states, "My home was destroyed, condemned, or disposed of under threat of condemnation and I do not plan to acquire a new home within 2 years of the event (see instructions)." Even if the taxpayer does not currently intend to replace the property within two years, accelerated repayment is not due until the tax year for the year in which the two-year replacement period expires. In some cases, a taxpayer may be unable or unwilling to replace a home within the two-year replacement period that provides an exception to the acceleration of repayment. In some of these cases, repayment may not be necessary due to the limitation based on gain. A taxpayer may have gain from an involuntary conversion due to either insurance proceeds (in the case of property that has been damaged or destroyed), condemnation awards, or selling price (in the case of property that has been sold under threat of condemnation). In this case, the taxpayer who does not replace the principal residence within the two years allowed must determine whether there was a gain or loss realized on the property. Section 36(f)(3) limits the repayment of the homebuyer credit to the amount of gain from the disposition of the property. If there is a loss or no gain, no accelerated repayment is required. However, for purposes of determining gain on the disposition, the property's adjusted basis must be reduced by the total amount of the homebuyer credit that was claimed. When there is a gain, that gain would be compared to the outstanding balance of the homebuyer credit. The smaller of the two would be the amount that is added to tax as accelerated repayment of the credit in the year in which the two-year replacement period expires. 1. My principal residence was destroyed by flooding in 2011. Do I have to repay the outstanding balance of my homebuyer credit with my 2011 tax return? No. The destruction of your home is an involuntary conversion. The homebuyer tax credit provisions include an exception to the repayment acceleration requirements when the property is destroyed. •    If, within two years of the date your property was destroyed, you replace your principal residence with another that would have qualified you for the credit if acquired in 2008, repayment of your credit will not be accelerated. •    If you do not replace the residence within this two-year period, your credit will be accelerated, but will be reported on the tax return for the tax year in which the two-year period expires. •    Despite the involuntary conversion, if your residence was purchased in 2008, you must continue to repay the usual amount ($500 per year if the credit was $7,500) with your tax returns. 2. My residence was not completely destroyed by the flooding, but it was severely damaged. I will have to move out of it while it is being repaired. Do I have to repay the outstanding balance of my homebuyer credit with my 2011 tax return? No. Generally, you do not abandon your principal residence due to temporary absences; therefore, it is likely that you would not be considered to have ceased using the property as your principal residence even if you actually move out of it while it is being repaired. Additionally, your property does not need to be completely destroyed for there to be an involuntary conversion; therefore, the involuntary conversion exception (explained above) would also apply. 3. My house was destroyed and was in a federally declared disaster area. Does this mean that repayment of my credit will not be accelerated if I replace my house within four years? No. The involuntary conversion exception for acceleration of repayment of the homebuyer tax credit requires you to replace the property within two years. There currently is no provision to expand that replacement period when the property is within a federally declared disaster area. 4. My house was destroyed or damaged in 2011. Do I have to do anything special when I file my 2011 tax return? Yes. You must file Form 5405 with your tax return. On it, you will enter the date on which the damage or destruction occurred and indicate that your house was damaged or destroyed (rather than sold, converted to business or rental use, or abandoned). You will also need to indicate whether you currently intend to replace your property within two years. 5. If I say that I am not going to replace my house, does it mean that I will owe a lot more in taxes for 2011? No. You are indicating that you currently do not intend to replace the property. If you do not replace the property, the accelerated repayment of the tax credit will not be reported on your tax return until 2013. If you change your mind and do replace the property within two years, there would be no accelerated repayment requirement. 6. I purchased my house in 2008 and it was destroyed in 2011. I started repaying the credit on my 2010 tax return. What do I need to repay in 2011 and subsequent years? •    You will need to continue paying your scheduled repayment amount ($500 if the credit was $7,500) in 2011 and 2012. •    If you replace your home within two years after its destruction, your repayment will not be accelerated. You will continue repaying your scheduled repayment amount each year. •    If you do not replace your house within the two-year replacement period, you generally would need to repay the outstanding balance on your credit ($6,000 if originally $7,500), showing it on your 2013 tax return. However, that repayment may be reduced or eliminated depending on whether there was a gain from the involuntary conversion. •    If there was no gain, you would not have to repay any more of the credit. •    If the gain was less than the outstanding balance on the credit, your repayment would be the amount of the gain. •    For purposes of calculating this gain, you would be required to reduce your cost basis in the house by the original amount of the credit.
