Form 5405 First Time Homebuyer Credit and Repayment of the Credit is used by eligible taxpayers who buy a home and qualify for the first time homebuyer credit. The Homebuyer Assistance and Improvement Act of 2010 signed by the President in July effectively extended the closing deadline from June 30 to Sept 30 for any eligible purchase that was entered into before April 30.
The IRS says in their July notice that those who entered into a purchase contract on or before April 30 but closed after that date should attach a copy of a signed contract showing all the parties names, signatures, property address, purchase price, and the date of the contract, attach to their tax return.
