where did you get this info?
according to the IRS website at:
http://www.irs.gov/newsroom/article/0,,id=179181,00.html
near the bottom of the page.
unless your one of those conspiracy theory guys, this kinds does sound like a rebate, or refund..whatever word you want to use.
am i missing something there?
and i quote:
Q. Will the payment I receive in 2008 reduce my 2008 refund or increase the amount I owe for 2008?
A. No, the Stimulus Payment will not reduce your refund or increase the amount you owe when you file your 2008 return.
