Oklahoma Car Sales Tax Calculator (2026)

• Since July 1, 2026 Oklahoma bases motor vehicle excise tax on the actual sales price rather than an average retail value.
• New vehicles pay 3.25% excise; used vehicles pay $20 on the first $1,500 plus 3.25% of the rest. A separate 1.25% sales tax also applies under 68 O.S. 2106.

Figured with Oklahoma's rules for a buyer from a dealer.

• Used car, no trade-in$781

  $18,000 price. Taxed on $18,000.

• New car with a trade-in$1,575

  $35,000 price, $10,000 trade-in. Taxed on $35,000. The trade-in does not lower the tax.

• New car with a trade-in and a rebate$1,935

  $45,000 price, $15,000 trade-in, $2,000 rebate. Taxed on $43,000. The trade-in does not lower the tax. The rebate saves $90.

These examples treat the agreed price as the taxable price. Where a state uses a book value instead, the tax can differ.

Oklahoma has no local tax on vehicles, so buyers in Oklahoma City, Tulsa and Norman and everywhere else in Oklahoma are figured at the same state rate: $1,350 on a new $30,000 car. Whether the tax applies to your purchase still depends on the rules above.

The calculator covers a car bought from a dealer. These rules apply to other ways of buying or bringing a car to Oklahoma.

Buying from a private seller

For cars bought on or after July 1, 2026, Oklahoma motor vehicle excise tax is figured on the actual sales price, including on private sales. The price is shown on the title assignment, electronic title bill of sale, bill of sale or Form 722-1 Declaration of Purchase Price. (content.govdelivery.com, checked Nov 10, 2026)

A car received as a gift

Only transfers made without payment between husband and wife or between parent and child are exempt from Oklahoma excise tax, with a Family Affidavit (Form 794). Gifts between in-laws or from grandparents to grandchildren are not exempt; a car obtained by inheritance is exempt. (oklahoma.gov, checked Nov 10, 2026)

Moving to Oklahoma with your car

A car brought into Oklahoma by someone moving from another state is exempt from excise tax if they owned and registered it in their former state at least 60 days before it had to be registered in Oklahoma. New residents have 30 days after establishing residency to register an out-of-state vehicle. (oklahoma.gov, checked Nov 10, 2026)

Active-duty military

Nonresident service members stationed in Oklahoma may register a car without excise tax if they already registered it in another state, with no 60-day minimum, and are not required to transfer their registration. Oklahoma-resident service members owe excise tax when ownership transfers to them, but those assigned out of state get a waiver of late registration penalties during the assignment and up to 60 days after. (oklahoma.gov, checked Nov 10, 2026)

Deadline to pay

Oklahoma excise tax is due when ownership or possession transfers and must be paid within 30 days. The new owner must title and register the car and pay excise and sales taxes within 30 calendar days of purchase. (oklahoma.gov, checked Nov 10, 2026)

Paying late

After the 30th day a daily penalty is added to unpaid excise tax until it is paid, capped at the amount of the tax. A separate late registration penalty starts on the 31st day at $1 per day, up to $100. (oklahoma.gov, checked Nov 10, 2026)
