The first-time homebuyer credit is similar to a 15-year interest-free loan. It is repaid in 15 equal annual installments beginning with the second tax year after the year the credit is claimed. You may need to adjust your withholding or make quarterly estimated tax payments to ensure you are not under-withheld.
Some exceptions apply to the repayment rule:
-If you die, any remaining annual installments are not due. If you filed a joint return and then you die, your surviving spouse would be required to repay his or her half of the remaining repayment amount.
-If you stop using the home as your main home, all remaining annual installments become due on the return for the year that happens. This includes situations where the main home becomes a vacation home or is converted to business or rental property. There are special rules for involuntary conversions. Taxpayers are urged to consult a professional to determine the tax consequences of an involuntary conversion.
-If you sell your home, all remaining annual installments become due on the return for the year of sale. The repayment is limited to the amount of gain on the sale, if the home is sold to an unrelated taxpayer. If there is no gain or if there is a loss on the sale, the remaining annual installments may be reduced or even eliminated. Taxpayers are urged to consult a professional to determine the tax consequences of a sale.
-If you transfer your home to your spouse, or, as part of a divorce settlement, to your former spouse, that person is responsible for making all subsequent installment payments.
Only purchases of a main home located in the United States qualify, and the home must have been purchased after April 8, 2008, and before July 1, 2009. For a home you construct, the purchase date is the date you first occupy the home.
