The Oklahoma Sales Tax Relief Credit is a refundable credit available to eligible Oklahoma residents who meet specific income and residency requirements. This credit is designed to provide relief from sales tax burdens for low-income individuals and families.
Eligibility Requirements
Residency: You must be a legal resident of Oklahoma for the entire tax year. A resident is defined as someone legally domiciled in the state for the full year.
Income Limit: Your total gross household income must not exceed $20,000 for the year. Household income includes the total gross income received by all persons living in the same household, whether or not the income is taxable for income tax purposes.
Exceptions to Income Limit: The income limit may be increased to $50,000 if you meet at least one of the following requirements:
- You can claim an exemption for your dependent;
- You or your spouse are 65 years of age or older by December 31, 2025; or
- You have a physical disability constituting a substantial handicap to employment (documentation may be required).
- If any of these conditions apply, your total gross household income limit is increased from $20,000 to $50,000. You must complete and provide Form 538-S if you qualify for the Sales Tax Relief/Credit.
Important Information
- Ineligibility: You are not eligible for the Sales Tax Relief Credit if you received Temporary Assistance for Needy Families (TANF) benefits for any month during 2025, were an inmate in the custody of the Oklahoma Department of Corrections for any portion of 2025, or were living in Oklahoma under a visa during 2025.
- If you or your spouse died during the tax year, that person does not qualify for the credit. However, if the death occurred after December 31, 2025, but before this form is filed, any credit or refund for the deceased will be paid to their estate.
- Credit Amount: The Sales Tax Relief Credit is $40 multiplied by the number of allowable personal exemptions you can claim, subject to the applicable eligibility requirements.
