How to apply for Oklahoma sales tax relief credit or refund (Form 538-S)
Oklahoma Tax Commission (OTC)
Who it's for
Oklahoma gives a yearly sales tax credit or refund to lower-income residents. The amount is $40 for each qualified exemption you claim, such as yourself, your spouse, and your dependents. You must have lived in Oklahoma for the whole year. You qualify if your total gross household income is $20,000 or less. You can also qualify with household income up to $50,000 if you or your spouse are 65 or older, you have a physical disability that is a substantial handicap to employment, or you can claim a dependent. If you file an Oklahoma income tax return, claim it on Form 511 by April 15. If you do not have to file a return, mail Form 538-S to the Oklahoma Tax Commission by June 30.
Household income counts everyone living in the home and almost every kind of income, including Social Security. People who got TANF in any month of the year cannot claim it. People who got aid to the aged, blind, or disabled, or Medicaid nursing home care, all year get their refund from Oklahoma Human Services instead. A late claim cannot be fixed with an amended return. The Oklahoma Tax Commission makes the final decision.
People who qualify for one senior program often qualify for others. See everything you may qualify for — free, no SSN, about five minutes.
