Lawmakers have given their final seal of approval to a $170 billion plan intended to spark the slowing economy.
The plan's centerpiece: tax rebates.
But questions remain about how the program will work, and officials at the Treasury Department and IRS are scurrying to work out the details.
In the meantime, here are some answers based on currently available government information and experts' analysis.
Do I qualify for a rebate and how much can I expect?
One-time rebates will be sent to at least 117 million low- and middle-income households, 20 million senior citizens living off of Social Security, and 250,000 disabled veterans.
To be eligible for a full rebate, single tax filers must have 2007 adjusted gross income (AGI) below $75,000 and joint filers must have AGI below $150,000.
