If you didn't file your tax return back in 2011, there could be hundreds, or even thousands, of dollars sitting out there with your name on it. But, if you don't claim that money soon, it will be gone forever.
The IRS owes $1 billion in refunds to about 1 million households that didn't file a tax return in 2011. But, you only have three years to claim that money, so when tax day passes this year, the government can officially keep the cash.
Are you in line for some money? The IRS believes that people from New York, Florida, California and Texas are the most likely to have an unclaimed refund.
