Promote tax compliance through serving taxpayers with transparency and fairness in administration of the tax code and unparalleled customer service.
Since 1931, the Oklahoma Tax Commission (OTC) has held the responsibility of the collection and administration of taxes, licenses and fees that impact Oklahomans. Currently, we collect and distribute over $11 billion to more than over 200 state agencies, funds and programs each year.
Additionally, we distribute dedicated funds to counties and municipalities throughout the state.
We are governed by three Governor-appointed and Oklahoma Senate-confirmed commissioners. The commissioners direct the administration and enforcement of Oklahoma state tax laws and the collection of a majority of all state-levied taxes and fees through its agency. Under the direction of the commissioners, an executive director oversees the general practices of the agency and is assisted by a team of division directors whose staff encompasses the agency.
Our Core Values guide everything we do:
It is because of these principles that we pride ourselves in having a flexible organization, keeping pace with shifts in technology, government structure and the ever-changing lifestyles of our taxpayers. To ensure we have the forward-thinkers necessary to maintain alignment with our Mission and Core Values, we have built a dynamic team of more than 600 dedicated staff committed to meeting the needs of taxpayers.
