How do I claim the tax credit? Do I need to complete a form or application? Are there documentation requirements?

You claim the tax credit on your federal income tax return. Specifically, home buyers should complete IRS Form 5405 to determine their tax credit amount, and then claim this amount on line 67 of the 1040 income tax form for 2009 returns (line 69 of the 1040 income tax form for 2008 returns). No other applications are required, and no pre-approval is necessary. However, you will want to be sure that you qualify for the credit under the income limits and repeat home buyer tests. Note that you cannot claim the credit on Form 5405 for an intended purchase for some future date; it must be a completed purchase. Home buyers must attach a copy of their HUD-1 settlement form (closing statement) to Form 5405 as proof of the completed home purchase.
