As the April 15 filing deadline looms, the Internal Revenue Service reminds taxpayers that after three years, any unclaimed 2021 tax year refunds go to the U.S. Treasury.

Alabamians who haven’t claimed their tax returns from 2021 will lose them if they don’t act before tax time this year. An estimated 18,100 Alabamians who did not file their form 1040 federal tax return for 2021 have a little more than a month to file before the refunds expire at the three-year mark.
