If you're thinking of buying a home, there could be a big bonus for you in the economic stimulus bill that's now before Congress.  Technically, the stimulus bill is actually changing the terms of the $7,500 tax credit that was issued as a part of the Housing Recovery Act, which Congress passed last summer. That legislation required that the tax credit be repaid over 15 years, making it more of a no-interest loan. Not surprisingly, the measure had little impact on the market. The stimulus bill now under consideration would make that tax credit a true credit that doesn't need to be repaid.

To be eligible, buyers cannot have owned a home for the past three years, and the new home has to be used as a primary residence. The credit phases out as income rises above $75,000 for singles and $150,000 for couples, and disappears entirely at $95,000 and $170,000, respectively.

Applying for it is easy, or at least as easy as doing your income taxes. Just claim it on your return. That's it. No other forms or papers have to be filed.

The Senate bill applies retroactively to any purchase completed between January 1, 2009 and the end of August. The House version is also retroactive to the start of the year, and expires at the end of June. As long as buyers don't sell for at least 36 months, they keep the money.

And the credit is refundable, meaning that it can be claimed even if the amount of the credit earned exceeds the buyer's tax liability. So even if your total tax bill comes to just $5,000, you can still qualify for a full $7,500 refund.

An earlier version of this story incorrectly stated that the tax credit for a home purchased in 2009 could only be taken off of 2009 taxes. However, homebuyers can choose to take the credit for 2008, according to the IRS. Even if they buy a home after they've filed their 2008 taxes, they can file an amended return.
