Time is running out for the 1.7 million people who qualified for a tax refund in 1998 but failed to file. 

These are folks who may have earned too little to be required to file but had taxes withheld from their wages. Or they are among those who had no taxes withheld but were eligible for a refundable tax credit available to those with low-incomes.

In cases like these the IRS gives you three years to file and claim your refund.

After that your hard-earned cash becomes the property of the U.S. Treasury. 

April 15 a total of $2.3 billion in refunds from 1998 could go to Uncle Sam if the money isn't claimed by then. 

That's about $1,300 for each person who failed to file. 

Make sure you're not one of them.
