Taxpayers eligible for the Earned Income Tax Credit for 2021 may also claim those funds if they file their returns for the year. Qualifying incomes are $21,430 for a single person without children or up to $57,414 for a married couple filing jointly with three or more qualifying children.

“Under the law, taxpayers usually have three years to file and claim their tax refunds. If they don’t file within three years, the money becomes the property of the U.S. Treasury,” according to the IRS.
