The IRS has issued a reminder that time is running out to claim your 2018 tax refund if you did not file a 2018 federal return. The deadline to file a 2018 IRS return and claim your refund is April 18, 2022. Filing a missed 2018 return may also qualify for the Earned Income Tax Credit (EITC) if you meet the requirements.
By law, there is a limited three year window to claim a refund. After that date, unclaimed 2018 federal tax refunds will become the property of the U.S. Treasury.
