Tax credit: 10% of the purchase price of a primary residence, up to a maximum of $8,000 for first-time homebuyers and $6,500 for repeat buyers. First-time homebuyers are defined as people who have not owned a home in the previous three years. Repeat buyers must have owned their current home at least five years. The credit cannot be used for houses costing more than $800,000.

Deadline for qualifying: Purchase agreements must be signed by April 30, 2010, and closings must be final by June 30.

Military deadline: The deadline is extended by a year for members of the military who have served outside the U.S. for at least 90 days from Jan. 1, 2009, to May 1, 2010.

Income limits: Individuals with annual incomes up to $125,000 and joint filers with incomes up to $225,000 qualify for the full credit. Individuals with incomes up to $145,000 and joint filers with incomes up to $245,000 qualify for reduced credits.

How to apply: Taxpayers can claim the credit on their federal income tax returns. If the credit exceeds their tax bill, the government will issue a payment. Taxpayers who want immediate refunds can amend their tax returns for 2008 to claim the credit.

Cost: $10.8 billion.

WASHINGTON (AP) — Congress took further steps to right the staggering economy by expanding a popular tax credit for homebuyers and extending unemployment checks for the growing legions of people running out of benefits with few job prospects.

The $24 billion package also contains tax credits aimed at struggling businesses.

The IRS says about 1.4 million people applied for the homebuyers credit through August, helping enliven the moribund housing market. The legislation would extend the program through June of next year, as long as the buyer signs a contract by the end of April. It also offers a $6,500 tax credit to those who have lived in their current residence at least five years.

The measure doubles the income ceiling for eligible individuals to $125,000. Homes must cost less than $800,000 to qualify.

The nearly 2 million who have exhausted their unemployment benefits or face termination of benefits, usually about $300 a week, before the end of the year would receive 14 weeks of additional benefits under the bill. The unemployed in those states where the jobless rate tops 8.5% would get six weeks on top of that.

The extension would be the fourth since June of last year and the first since the $787 billion stimulus package was enacted last February. The unemployed in the hardest-hit states could, once the bill becomes law, receive a maximum of 99 weeks of benefits, well above the previous record of 65 weeks in the 1970s.

The bill would also allow businesses that have incurred losses in 2008 and 2009 to seek refunds for taxes paid on profits over the past five years.

The two tax credits, each costing more than $10 billion over 10 years, are paid for by delaying enactment of a law giving international companies more leeway in how they allocate interest expenses between U.S. and foreign sources in determining tax liabilities.
