The Oklahoma Tax Commission will open the state income tax filing season on Monday, January 23, 2023. This date is in coordination with the Internal Revenue Service (IRS).
The filing deadline to submit 2022 Oklahoma income tax returns is Tuesday, April 18, 2023. This date matches the filing deadline for 2022 federal income tax returns. According to the IRS, the delay is a result of Emancipation Day, a Washington D.C. holiday that acts the same as all other federal holidays and falls on Monday, April 17. All other due dates remain the same.
Taxpayers looking for assistance can save time by accessing Oklahoma’s Taxpayer Access Point online, or by scheduling an in-person appointment at the OTC’s Taxpayer Resource Center located in downtown Oklahoma City.
