Sales tax on a car in Oklahoma

Oklahoma charges a state motor vehicle excise tax (3.25%) plus vehicle sales tax (1.25%) of 4.5% on vehicle purchases.

Vehicle sales that are subject to the excise tax are not subject to city or county sales taxes.

The price used for excise tax must be within 20% of the vehicle's average retail value in the state's reference guide. Both taxes are paid when the vehicle is titled.

Does a trade-in lower the tax?

The 3.25% excise tax is charged on the purchase price with no reduction for a trade-in. The Oklahoma Tax Commission states that a 2023 law (SB 984) allows the trade-in value to reduce the price used for the 1.25% sales tax.

Dealer doc fees in Oklahoma

We could not confirm from an official source whether the state limits the documentation fee. Ask the dealer for the fee in writing and compare it with other dealers.

Whatever the rule, the fee is part of your out-the-door price. Ask for it in the written quote and negotiate the total, not the line. See dealer fees explained.

Title and registration

Titles and registrations are handled by the Service Oklahoma. Taxes and registration are due within 30 days of purchase, and a penalty of $1 per day, up to $100, starts on the 31st day. Service Oklahoma also states that a title must be obtained within 2 months of purchase.

Also worth knowing

  • A vehicle bought from a licensed dealer may be driven for 30 days on the dealer's temporary tag.
  • A dealer's documentary fee is not included in the price used to calculate excise tax.
  • In a private sale, the vehicle may be driven without plates for up to 5 days if a dated, notarized bill of sale is carried.
