Nearly two million U.S. taxpayers have over 2 billion dollars in unclaimed income tax refunds that they will forfeit if they don't file within three years of the tax year for which the refund applies. If you think you couldn't possibly be one of them, think again.

How Tax Refunds Go Unclaimed

Every year, millions of American taxpayers their income tax refunds unclaimed, often because they didn't realize they even had one coming. The problem often arises because you're not required to file a return unless you earned over a certain amount.

People often make the mistake of thinking that because they aren't legally required to file an income tax return, they don't need to bother. But more often than not, those very same people would receive a refund if they did file, even though they're not required to.

According to a recent article on the Internal Revenue Service (IRS) website, there are also millions of dollars in unclaimed tax refunds that have been returned and marked undeliverable. So who are these people leaving their tax refunds on the table?

Whose Unclaimed Tax Refunds Are These?

There are a wide range of reasons why a tax refund may go unclaimed, but there are some patterns among those people who are owed unclaimed returns. The most common groups who unknowingly leave unclaimed refunds to the Internal Revenue Service (IRS) include:

  • Students
  • Workers who work part-time or for only part of the year but had income taxes withheld
  • Self-employed workers with low earnings who made estimated tax payments but didn't file a return because their earnings were below the threshold
  • Individuals who fail to file a final return on behalf of a deceased family member who is due a refund
  • Individuals who qualified for the earned income credit but didn't file a return because their earnings were below the threshold

What Is the Earned Income Credit?

The last group mentioned above relates to a specific tax credit called the earned income credit (EIC). While deductions are a helpful tool for reducing tax burdens, tax credits are by far the most coveted. That's because a tax credit actually reduces the taxes an individual or couple owes dollar for dollar, whereas a deduction simply lowers the total amount of taxable income. 

The earned income credit helps qualified low-income individuals and families by paying them back some of the taxes they paid, and in some cases, paying them even though they owed no taxes, to begin with. But a tax credit is only good if it is used.

How to Claim Your Unclaimed Tax Refund

If you think that you may fall into one of the groups above, you might want to see if the IRS owes you money. First, check your records to make sure you've filed a tax return for each of the last three years that you had earnings.

Review your returns for the last three years to make sure they're accurate and to determine if you were eligible for the earned income credit but didn't claim it. While the law allows three years from the filing deadline (April 15th) to file your income tax return to claim a refund, if you don't file within the time limit, the money is lost to you forever.

To obtain tax returns for previous years, visit the IRS website at or call 1-800-TAX FORM (1-800-829-3676). Then claiming your refund could be as easy as filing returns for the last three years if you've overlooked a refund or earned income credit. In fact, it could mean hundreds or thousands of dollars in your pocket.

If you were one of the many who were expecting a refund, but never received it, you might want to check out the "Where's My Refund?" tool on the IRS website. Tax refund checks are mailed to your last known address and can be returned to the IRS if you move and fail to provide your new address to the IRS or the U.S. Postal Service. You can update your address online or by filing Form 8822, which is available online or by calling the 800 number above.
