Filing your Oklahoma state income tax return

The filing status for Oklahoma state income tax purposes must be the same as on your federal return, with one exception. This exception applies to married taxpayers who file a joint Federal return where one spouse is an Oklahoma resident, and the other is a nonresident civilian.

Likewise, if you itemized on your federal income tax return, you must use this itemized amount on your Oklahoma return. If you use the Federal standard deduction, you must use the Oklahoma standard deduction.

There are many state income tax credits for Oklahoma. The most common nonrefundable credits are:

  • child care credit
  • credit for taxes paid another state.

The refundable credits are:

  • low income property tax credit,
  • sales tax relief credit,
  • tornado tax credit and
  • earned income credit.

The Form 511CR lists the other nonrefundable credits.

Residents of Oklahoma are taxed on out-of-state retirement income. However, there are deductions allowed for retirees. These are listed on Schedule 511-A, lines 3,4 & 5.

Oklahoma does not have special tax rates for capital gains. Capital gains are taxed at the same rate as the rest of the income.

Nonresidents are still required to file if their income exceeds $1,000 from Oklahoma sources. So, if you work in Oklahoma and gross at least $1,000, you will be required to file an Oklahoma return. Nonresidents file Form 511NR.

Sidebar
You can work on your Oklahoma tax return online while filing your federal return (you can work on it for free, and pay nothing until you are ready to file).

Note: if you are filing more than one state return, you must file a paper return for each additional state, as TurboTax for The Web only allows one state prep.
