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 charitable contribution/checkoff provisions.
How to Donate
- On Form 511, complete the applicable charitable contribution schedule and enter the whole-dollar amount you wish to contribute to the CASA fund.
- 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.
Additional Information
- The CASA contribution is a voluntary contribution and does not reduce Oklahoma taxable income or directly reduce Oklahoma income tax liability.
- Taxpayers should follow the current 2025 Form 511 and Schedule 511-H instructions for the applicable contribution option and reporting procedure.
- If a charitable contribution schedule is completed, it must be attached to the return. Failure to include a required schedule may delay refund processing.
- The separate mailing-address information previously included should be omitted unless supported by a current official Oklahoma CASA or Oklahoma Attorney General source.
