Oklahoma Tax, Title and License Calculator

Oklahoma charges a 3.25% vehicle excise tax on a new car’s price, or $20 plus 3.25% of a used car’s price above $1,500. A separate 1.25% sales tax also applies. Since July 1, 2026, a trade-in no longer lowers the excise tax. The tag costs $26 to $96 a year by age, and the title is $11.

Use this Oklahoma tax, title and license calculator to estimate the excise tax, sales tax and Service Oklahoma fees on a new or used car. The guide below walks through each rule.

Checked against Service Oklahoma, Oklahoma Administrative Code 670:20-45-3 and HB 1183 (effective July 1, 2026) on October 13, 2026. This is an independent estimate. Service Oklahoma and your tag agent set the final amount.

Oklahoma Car Tax and Fees at a Glance

How Oklahoma Vehicle Excise Tax Is Calculated

New car: excise = price × 3.25% Used car: excise = $20 + (price − $1,500) × 3.25%

Oklahoma’s main car tax is the vehicle excise tax, collected by your tag agent when you title the car. There’s no city or county add-on. The price must be within 20% of the car’s average retail value in the state’s guides. If it isn’t, Service Oklahoma sets a taxable value within that range.

Does a trade-in lower the excise tax?

Not anymore. HB 1183, effective July 1, 2026, says the taxable value is the actual sales price before any discounts or credits for a trade-in. A $40,000 car with a $10,000 trade-in is taxed on $40,000. Next door, Kansas lets a trade-in lower the tax.

Are dealer fees taxed?

Doc fees, financing, insurance and maintenance agreements aren’t part of the excise base.

What about the 1.25% sales tax?

Since July 1, 2017, Oklahoma has also charged a 1.25% sales tax on vehicle purchases. Bills to repeal it have been filed, and one passed in 2022 but was vetoed. It still applies in 2026.

How Much Is Car Tax in Oklahoma?

New cars

Used cars

Some other states handle cheap used cars differently. Arkansas has reduced rates on cheap used cars.

Example 1: New car from a dealer

Assumptions: $40,000 price, $10,000 trade-in, new tag and title, gas engine, bought after July 1, 2026.

Example 2: Six-year-old car from a private seller

You pay $12,000. Excise is $20 + ($10,500 × 3.25%) = $361.25. Sales tax is $150. Add $86 registration (years 5–8), $11 title, $17 transfer and $1.50, for $626.75.

Oklahoma Tag, Title and Other Fees

Oklahoma EV and plug-in hybrid fees

These are yearly fees on top of the regular tag fee.

Family Transfers, Deadlines and Out-of-State Purchases

Transfers between parents and children and between spouses are exempt from excise tax with Form 794. Divorce transfers, trusts and dropping a name from a title are exempt too. A 100% disabled veteran can get one vehicle exempt every three years.

The excise tax is due within 30 days of getting the car. After that, a daily penalty applies, up to the amount of the tax. Late registration costs $1 a day, up to $100.

Oklahoma’s excise is collected when you title the car here. If you’re comparing a purchase across the border, note that Texas charges 6.25% sales tax and Missouri bases tax on your home address. Cars titled out of state need a $4 VIN inspection before Oklahoma titles them.
