How is the amount of the tax credit determined?
The tax credit is equal to 10 percent of the home’s purchase price up to a maximum of $8,000 for first time buyers. $6,500 for repeat buyers.

If my modified adjusted gross income (MAGI) is above the limit, do I qualify for any tax credit?
Possibly. It depends on your income. Partial credits of less than $8,000 are available for some taxpayers whose MAGI exceeds the phaseout limits.

How do I claim the tax credit? Do I need to complete a form or application?
Participating in the tax credit program is easy. 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 69 of their 1040 income tax return. No other applications or forms 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 first-time home buyer tests.

Repeat buyers must Purchaser must attach documentation of purchase to tax return

What types of homes will qualify for the tax credit?
Any home that will be used as a principal residence will qualify for the credit. This includes single-family detached homes, attached homes like townhouses and condominiums, manufactured homes (also known as mobile homes) and houseboats. The definition of principal residence is identical to the one used to determine whether you may qualify for the $250,000 / $500,000 capital gain tax exclusion for principal residences.

I read that the tax credit is "refundable." What does that mean?
The fact that the credit is refundable means that the home buyer credit can be claimed even if the taxpayer has little or no federal income tax liability to offset. Typically this involves the government sending the taxpayer a check for a portion or even all of the amount of the refundable tax credit.

For example, if a qualified home buyer expected, notwithstanding the tax credit, federal income tax liability of $5,000 and had tax withholding of $4,000 for the year, then without the tax credit the taxpayer would owe the IRS $1,000 on April 15th. Suppose now that the taxpayer qualified for the $8,000 home buyer tax credit. As a result, the taxpayer would receive a check for $7,000 ($8,000 minus the $1,000 owed).

I purchased a home in early 2009 and have already filed to receive the $7,500 tax credit on my 2008 tax returns. How can I claim the new $8,000 tax credit instead?
Home buyers in this situation may file an amended 2008 tax return with a 1040X form. You should consult with a tax advisor to ensure you file this return properly.

Instead of buying a new home from a home builder, I hired a contractor to construct a home on a lot that I already own. Do I still qualify for the tax credit?
Yes. For the purposes of the home buyer tax credit, a principal residence that is constructed by the home owner is treated by the tax code as having been "purchased" on the date the owner first occupies the house. In this situation, the date of first occupancy must be on or after January 1, 2009 and before December 1, 2009.

In contrast, for newly-constructed homes bought from a home builder, eligibility for the tax credit is determined by the settlement date.

Can I claim the tax credit if I finance the purchase of my home under a mortgage revenue bond (MRB) program?
Yes. The tax credit can be combined with the MRB home buyer program. Note that first-time home buyers who purchased a home in 2008 may not claim the tax credit if they are participating in an MRB program.

I am not a U.S. citizen. Can I claim the tax credit?
Maybe. Anyone who is not a nonresident alien (as defined by the IRS), who has not owned a principal residence in the previous three years and who meets the income limits test may claim the tax credit for a qualified home purchase. The IRS provides a definition of "nonresident alien" in IRS Publication 519.

Is a tax credit the same as a tax deduction?
No. A tax credit is a dollar-for-dollar reduction in what the taxpayer owes. That means that a taxpayer who owes $8,000 in income taxes and who receives an $8,000 tax credit would owe nothing to the IRS.

A tax deduction is subtracted from the amount of income that is taxed. Using the same example, assume the taxpayer is in the 15 percent tax bracket and owes $8,000 in income taxes. If the taxpayer receives an $8,000 deduction, the taxpayer’s tax liability would be reduced by $1,200 (15 percent of $8,000), or lowered from $8,000 to $6,800.

Is there any way for a home buyer to access the money allocable to the credit sooner than waiting to file their 2009 tax return?
Yes. Prospective home buyers who believe they qualify for the tax credit are permitted to reduce their income tax withholding. Reducing tax withholding (up to the amount of the credit) will enable the buyer to accumulate cash by raising his/her take home pay. This money can then be applied to the down payment.
Buyers should adjust their withholding amount on their W-4 via their employer or through their quarterly estimated tax payment. IRS Publication 919 contains rules and guidelines for income tax withholding. Prospective home buyers should note that if income tax withholding is reduced and the tax credit qualified purchase does not occur, then the individual would be liable for repayment to the IRS of income tax and possible interest charges and penalties.
