In a newly issued FAQ on the 2021 earned income tax credit (EITC), the IRS spells out what the credit is, which taxpayers are eligible for the EITC and how to claim it.
The EITC helps low- to moderate-income workers and families in the form of a credit to either reduce the taxes owed or an added payment to increase a tax refund.
For 2021, the EITC is generally available to filers without qualifying children who are at least 19 years old with earned income below $21,430 or $27,380 for spouses filing a joint return. See the FAQ.
