Tax Expenditure Report

Under a provision of Oklahoma law passed in 1996, the Oklahoma Tax Commission is tasked with preparing a biannual report that provides the Commission’s “best estimate of the amount of state revenue that would have been collected but for the existence of each exclusion, deduction, credit, exemption, deferral, or other preferential tax treatment allowed by law for the previous fiscal year.” The report is organized by tax type and provides estimates of lost revenue based upon information from actual tax returns and secondary data sources. The most recent Tax Expenditure Report was released in October 2020; the next one is due October 2022.
