Oct. 29 (Bloomberg) -- The Obama administration endorsed plans to extend an $8,000 tax credit for first-time homebuyers, saying it is helping stabilize the nation's housing market.

The tax break, enacted earlier this year as part of the $787 billion economic stimulus package, has "brought new families into the housing market and contributed to three consecutive months of rising home prices," Treasury Secretary Timothy Geithner said today in a statement. The tax break will expire Nov. 30 unless Congress intervenes.

Senate Democrats have announced plans to extend the credit until April 30, while expanding it to include higher-income Americans and some who already own homes.

Senate Finance Committee Chairman Max Baucus said today the new plan would offer a $6,500 credit for homebuyers who have lived in their prior residence for at least five years. Couples earning up to $225,000 and individuals up to $125,000 would qualify for the break, Baucus said. That's up from the current $75,000 limit for individuals and $150,000 for couples.

"The success of the American economy is closely tied to the success of the housing market; by helping to stabilize the housing market, the homebuyer tax credit has helped to shore up the economy as it begins to recover," said Baucus, a Montana Democrat. "This would enable an even greater number of potential homebuyers to take the credit."

Millions of renters earn more than $75,000, he said.
