The IRS may owe you money, and if you don't claim it by Tax Day, April 17, you will lose it.
The federal agency is sitting on more than $1.1 billion that taxpayers never claimed from 2014, but the chance to retroactively get it expires after three years.
Texas has the most taxpayers who are owed money; more than 108,000 Texans with total potential refunds of $122 million, according to the IRS.
To find out if you are owed money, you can call or check your refund status online or call the IRS toll-free at 800-829-1040.
If you are owed money, you will have to file for the years you are due a refund to collect the money.
