I have retired from teaching in Oklahoma and have begun teaching in texas. I am now receiving a pension from Oklahoma Retirement System. Is pension taxable by Oklahoma?

Where do you live?

If you are a Texas resident, you would not have to pay Oklahoma tax on it.  Retirement income is only taxable in the state you are a resident of (if it is taxed) when it was received.

If you are an Oklahoma resident, each individual, may exclude their retirement benefits, up to $10,000, but not to exceed the amount included in the Federal Adjusted Gross Income. (To be eligible, you must have retirement income in your name.)

The retirement benefits must be received from the following: the civil service of the United States*, the Oklahoma Public Employees Retirement System of Oklahoma, the Oklahoma Teacher's Retirement System, the Oklahoma Law Enforcement Retirement System, the Oklahoma Firefighters Pension and Retirement System, the Oklahoma Police Pension and Retirement System, the Employee retirement systems created by counties pursuant to Sections 951 et seq. of Title 19 of the Oklahoma Statutes, the Uniform Retirement System for Justices and Judges, the Oklahoma Wildlife Conservation Department Retirement Fund, the Oklahoma Employment Security Commission Retirement Plan, or the Employee retirement systems created by municipalities pursuant to Sections 48 - 101 et seq. of Title 11 of the Oklahoma Statutes.
