The last minute bill passed by the Senate on Tuesday evening extends 54 tax breaks until the end of this year, enabling taxpayers to claim them on their 2014 returns.
Lawmakers from both parties say they're disappointed that they weren't able to extend the tax breaks beyond this year.
"This package of incentives? Which applies only to 2014? Will last two more weeks before families and businesses will be thrown back into the dark about what taxes they owe," says Sen. Ron Wyden, D-Ore., chairman of the Senate Finance Committee. "This tax bill doesn't have the shelf life of a carton of eggs."
The biggest tax break for individuals allows people who live in states that don't have an income tax to deduct state and local sales taxes on their federal returns.
Another break protects struggling homeowners who get their mortgages reduced from paying income taxes on the amount of debt that was forgiven.
Here is a list of some of the tax breaks, from The Associated Press.
