Also, the IRS has created an Economic Stimulus Payment Calculator (www.irs.gov/app/espc) which will provide you the amount of your refund (maximum is $600 for single/head of household taxpayers but generally no less than $300, as long as you qualify; maximum for married couples filing jointly is $1,200, but generally no less than $600, as long as the couple qualifies). When using the calculator provided, make sure you have a copy of your 2008 return, which will have the info you need to determine your Stimulus Payment. The calculator will also tell you, depending on the numbers you plug in, if you qualify for the rebate. Generally, for single or head of household taxpayers, if your tax liability was at least $3,000 in 2007, you'll qualify for the maximum. REMEMBER ALL OF THIS IS DEPENDENT ON THE FACT THAT YOU HAVE FILED & THE I.R.S. HAS PROCESSED A 2007 TAX RETURN BY THE TIME THE CHECKS ARE DUE TO BE SENT OUT.
