SB 1405 Oklahoma Senate · 2026 Regular Session

Tax refund donation; reauthorizing checkoff for Wildlife Diversity Fund. Effective date.

SB 1405 reauthorizes a voluntary tax checkoff on Oklahoma state income tax returns, allowing taxpayers to donate a portion of their refund to the Wildlife Diversity Fund. The fund, managed by the Oklahoma Wildlife Conservation Commission, supports conservation efforts for nongame wildlife (species not classified as game or furbearer). Taxpayers who donate by mistake can request a refund within three years, and the reauthorized checkoff takes effect January 1, 2027. This bill updates statutory language to maintain the existing donation mechanism without altering its core purpose.
