Just a note to U.S. readers. Be aware that the money being delivered to you this May from the IRS is only an advance and will be taken back out of your 2009 refund.
Quoted from CNN
"The checks are an advance on next year's refunds, and most, if not all of the money, will be deducted from taxpayers' refunds in 12 months' time."
Don't be thinking you're going to get a refund next year without deducting extra this year (or be smart, deposit into a savings account).
