To claim the credit as part of your 2009 return, you will need: The standard Form 1040 and Form 5405 for the home buyer tax credit.
1. First begin Form 1040.
2. Be sure to take note of your adjusted gross income, which you enter on lines 37 of the form. Form 5405 actually requires you to note your modified adjusted gross income, but that affects few people, so most will just use their adjusted gross income.
