The Homebuyer Assistance and Improvement Act of 2010, signed by President Obama on July 2, extends the closing deadline from June 30 to September 30 for any eligible homebuyer. Eligible taxpayers who contracted to buy a home, qualifying for the first-time homebuyer credit, before the end of April now have until September 30, 2010, to close the deal.

To avoid refund delays, those who entered into a purchase contract on or before April 30, but closed after that date, should attach a copy of the pages to their return from the signed contract showing all parties’ names and signatures if required by local law, the property address, the purchase price, and the date of the contract.
