Income Tax Deductions for Oklahoma

Standard Deduction

If you claimed the standard deduction on your federal return, you must claim the standard deduction on your Oklahoma return. In Oklahoma, the standard deduction amount depends on your filing status.

For the 2021 tax year, the standard deductions are:

• Single or married filing separately: $6,350
• Head of household: $9,350
• Married filing jointly or Qualifying widower:  $12,700

Itemized Deductions

If you itemized deductions on your federal tax return, you’re required to itemize deductions on your Oklahoma return. In Oklahoma, your itemized deductions are largely based on your federal deductions, except for any state and local sales tax or income tax deducted. Those two deductions can’t be taken in Oklahoma and must be added back into your income.

On your state return, your total amount of deductions must be limited to $17,000. The only exceptions are charitable contributions and medical expenses, which aren’t subject to the $17,000 limit.

Other Deductions

In addition, Oklahoma allows for a number of state-specific deductions, including:

Qualified adoption expense

Taxpayers who have recently adopted a child may deduct certain non-recurring adoption expenses up to $20,000 per calendar year. The expenses must be directly related to the adoption, such as adoption fees, attorney’s fees, and court costs. The expenses must be deducted in the year incurred.

Qualifying disability deduction

Taxpayers who have a qualifying physical disability that constitutes a substantial handicap to employment may deduct the expenses incurred while modifying a motor vehicle, home, or workplace in a manner necessary to compensate for their disability. However, they must also provide a schedule detailing the expenses incurred and a description of the disability.

Contributions to Oklahoma 529 College Savings Plan and OklahomaDream 529 account(s)

Oklahoma taxpayers may also deduct contributions to qualified 529 accounts. Those married filing jointly can deduct up to $20,000, while all other filing statuses can deduct up to $10,000. They may deduct contributions for the current tax year, as well as contributions for prior years that occurred after Dec. 31, 2004 up to the limit.

Oklahoma State Income Tax Credits

Child Care / Child Tax Credit

If your federal adjusted gross income (AGI) is less than $100,000 and you’re allowed a credit for child care expenses or the child tax credit on your federal income tax return, you’ll be eligible for a credit against your Oklahoma tax.

The credit is equal to 20% of the credit for childcare expenses allowed by the Internal Revenue Code (IRC) or 5% of the child tax credit allowed by the IRC, whichever is greater.

If you make more than $100,000, you won’t be eligible for this credit.

This credit is nonrefundable and doesn’t carry forward.

Earned Income Tax Credit

On their Oklahoma return, taxpayers are allowed a credit equal to 5% of the earned income credit allowed on their federal return.

This credit is nonrefundable for the 2021 tax year and doesn’t carry forward.

Tax Paid to Another State Tax Credit

If you earned income in another state, you must report that amount on your Oklahoma return. However, you may be eligible for a tax credit worth a percentage of your earned income. If you’ve claimed a similar credit in another state, you can’t claim this credit on your Oklahoma return.

This credit is nonrefundable and doesn’t carry forward.

Do I Have to Pay Income Tax in Oklahoma?

Whether or not you have to file an Oklahoma income tax return depends on your income and residency status.

• Residents: You must file a return if your income is higher than your allowable standard deduction amount plus any personal exemptions.
• Part-year residents: You must follow the same requirements as a resident. Additionally, a return must be filed if you earned more than $1,000 from Oklahoma sources during your nonresidency period.
• Nonresidents: If you earned more than $1,000 from Oklahoma sources, you must file a return in the state.
