Oklahoma taxpayers may voluntarily designate an amount of their state income-tax overpayment to support programs for volunteers who serve as Court Appointed Special Advocates (CASA) for abused or neglected children. The contribution is made through the Oklahoma income-tax donation/checkoff provisions.
How to Donate
- On Form 511, complete Schedule 511-H and designate the whole-dollar amount you wish to contribute to the CASA fund. Form 511 line 36 is labeled “Donations (Original return only),” and Schedule 511-H provides taxpayers with the opportunity to make a financial gift from their refund to a variety of Oklahoma organizations.
- If you complete Schedule 511-H, you must include the completed schedule with your Form 511. The 2025 Form 511 instructions specifically state that any completed Schedule 511-A through 511-I must be submitted with the return.
- Oklahoma requires amounts reported on the return and schedules to be rounded to the nearest whole dollar.
- A voluntary contribution designated on the return reduces the amount of an overpayment available to be refunded to you. It is not an Oklahoma income-tax credit or deduction.
- Nonresidents may also contribute from their overpayment by using Schedule 511-NR-G
Additional Information
- The CASA contribution is a voluntary contribution and does not reduce Oklahoma taxable income or directly reduce Oklahoma income-tax liability. It reduces the amount of the refund otherwise payable to you.
- Taxpayers should follow the current 2025 Form 511 and Schedule 511-H instructions for the applicable contribution option and reporting procedure (nonresidents user Schedule 511-NR-G).
- A taxpayer who is not receiving a refund may still donate. In that situation, the contribution is mailed directly to:
- Oklahoma CASA Association, Inc.
PO Box 54946
Oklahoma City, OK 73154
