Did you or someone you know miss filing a 2021 tax return? If so, and if you were expecting a refund, time’s running out. The deadline to file and claim a 2021 tax year refund is April 15, 2025. The IRS estimates that refunds worth more than $1 billion are still unclaimed by taxpayers who haven’t filed 2021 federal tax returns. The median refund is expected to be $781. Taxpayers generally have three years to file and claim refunds. If they miss the deadline, the refunds become property of the U.S. Treasury. Taxpayers seeking 2021 refunds may have their refunds held if they haven’t filed tax returns for 2022 and 2023 or applied to amounts they owe the IRS or state tax agencies. We can help.
