Oklahoma EITC Overview
Oklahoma is one of the states that offers its own Earned Income Tax Credit on top of the federal EITC. The Oklahoma state EITC is worth up to 5% of your federal credit amount and is refundable.
Because the Oklahoma EITC is refundable, you can receive the credit even if you owe no state income tax. This means qualifying residents can receive both a federal EITC refund and a Oklahoma state EITC refund. For a worker with three or more children receiving the maximum federal EITC of $7,830, the state credit could add up to $392 in additional benefits.
To claim the Oklahoma state EITC, you must first qualify for the federal Earned Income Tax Credit. File your Oklahoma state tax return and claim the state credit on the appropriate line or schedule. The state credit is typically calculated automatically when you file using tax software.
