Payback Unlike some past tax credit programs, this one requires beneficiaries to repay the credit over an extended period of years. Starting in the second tax year after purchase and continuing for up to 15 years, taxpayers are expected to make pro-rata repayments to the government on their federal filings. Over a 15-year payback period for the full $7,500 credit, the cost would be $500 a year. If you sell the house before the end of the repayment period, and you have no gain on the sale, you won't be expected to pay the credit back from the proceeds. If you have a net gain, the "recapture" cannot exceed the amount of your gain. In other words, the federal government is taking on all or much of the risk that the value of your new house won't increase over time.
At its core, the new tax credit functions very much like an interest-free loan for up to $7,500. You pay the principal back in increments over time, but there's no interest charge to you.
