If you haven't filed your 2012 taxes yet, you have less than a month to do so. But if you haven't filed your 2009 taxes yet, experts say you could be losing out on a piece of a billion dollar pie.
The Internal Revenue Service says they have nearly $1 billion in unclaimed returns and you only have 3 years to claim a refund before the money is turned over the Treasury Department. The IRS says you have to file your federal tax returns from 2009 before April 15 or your money will be withheld.
According to the IRS, about half of the potential refunds may be larger than $500.
