Oklahomans receiving a refund this tax season can support wildlife conservation efforts by donating all or a portion of their refund to the Wildlife Department’s Wildlife Diversity Program. Tax refund donations can be made on Schedule 511-H of the 2025 state return, which must be filed with the Oklahoma Tax Commission by April 15, 2026.
Income Tax Form 511 is available from the Oklahoma Tax Commission webpage, oklahoma.gov/tax, along with free filing options.
The race is on to file income taxes before April 15 and benefit wildlife like the prairie racerunner.
The Wildlife Department does not receive any state tax appropriations and instead relies on hunting and fishing license sales and donations to match federal conservation grants. Learn more about our nongame conservation work at wildlifedepartment.com.
