AutoTaxCalculatorHow much is car tax in Oklahoma?
New car: 3.25% excise + 1.25% sales tax = 4.5% of the purchase price. A $36,000 new car owes $1,170 excise and $450 sales tax, or $1,620. Used car: $20 on the first $1,500, 3.25% on the rest, plus 1.25% sales tax.
Oklahoma collects these taxes when you title the vehicle at a tag agency or through Service Oklahoma, not at the dealership register. Many dealers collect them for you and pass them along, but the amounts are the same either way. Unlike most states, Oklahoma has no local vehicle tax. Whether you buy in Tulsa, Norman or a small town, the rate is the same.
The motor vehicle excise tax
The excise tax is Oklahoma's main tax on vehicle purchases, set by 68 O.S. § 2103. It's charged every time legal ownership changes, unless an exemption applies.
| Vehicle | Excise tax |
|---|---|
| New vehicle, first sale by a dealer | 3.25% of the value |
| Used vehicle (every later sale) | $20 on the first $1,500, plus 3.25% of the remaining value |
A new car sold by a dealer for the first time always gets the new-vehicle rate, regardless of model year. If it's resold during the same year, the second sale is taxed at the used rate. The excise tax is rounded to the nearest dollar. For any used car worth $1,500 or less, the excise tax is a flat $20.
The 1.25% vehicle sales tax
Since July 1, 2017, Oklahoma has also charged a 1.25% state sales tax on motor vehicle purchases. Before that, vehicles were fully exempt from sales tax because they paid excise tax. Combined with the excise tax, a new car carries 4.5% in total. The Tax Commission's rules say no sales tax is due when ownership changes without a purchase, such as an inheritance or a qualifying family gift.
No trade-in credit in Oklahoma
This is the rule that surprises most buyers. Oklahoma Tax Commission rule 710:60 defines the taxable value as the actual sales price excluding any trade-in credit. That applies to both the excise tax and the 1.25% sales tax. If you buy a $36,000 car and trade in a car worth $10,000, you're still taxed on $36,000.
The price you report also has to be close to the market: it must be within 20% of the average retail value in the Tax Commission's reference guide. If it isn't, the Commission sets a taxable value instead. Documentary fees, financing fees, insurance and service contracts are left out of the taxable price.
Oklahoma tag, title and registration fees
Standard vehicle registration falls as the vehicle ages:
| Registration year | Yearly fee |
|---|---|
| 1st–4th year | $96.00 |
| 5th–8th year | $86.00 |
| 9th–12th year | $66.00 |
| 13th–16th year | $46.00 |
| 17th year and older | $26.00 |
When you title a purchase, Service Oklahoma also lists an $11 title fee and a $1.50 insurance fee. A vehicle coming from another state needs a $4 VIN inspection. Service Oklahoma's fee list also includes a $17 transfer fee and a tire tax that varies by vehicle.
Worked examples
New $36,000 pickup from an Oklahoma City dealer
- Excise tax: $36,000 × 3.25% = $1,170
- Sales tax: $36,000 × 1.25% = $450.00
- Fees: $96 registration + $11 title + $1.50 insurance = $108.50
- Total: $1,728.50
Used $18,000 sedan in its 6th year, bought from a private seller
- Excise tax: $20 + ($18,000 − $1,500) × 3.25% = $20 + $536.25 = $556.25, rounded to $556
- Sales tax: $18,000 × 1.25% = $225.00
- Fees: $86 registration + $11 title + $1.50 insurance = $98.50
- Total: $879.50
Using this as an Oklahoma car tax estimator
Service Oklahoma runs its own tax estimator for newly purchased vehicles, and it uses the Commission's valuation guide. Our calculator uses the price you enter, so the two should match as long as your price is within the 20% band. Where they differ, the official figure wins.
Who doesn't pay excise tax
- New residents: a vehicle you owned and registered in your former state at least 60 days before it has to be registered in Oklahoma. Nonresident military members stationed in Oklahoma are exempt without the 60-day limit.
- Family transfers: gifts between spouses, or between parents and children, with Form 794 (Family Affidavit). Siblings, grandparents and in-laws don't qualify.
- Inheritance, divorce and trusts: exempt with the right documents.
- 100% disabled veterans: one vehicle every three years.
Frequently asked questions
Is there a late penalty on Oklahoma excise tax?
Yes. Excise tax becomes delinquent 30 days after you take ownership. After that, the penalty is $1 per day, capped at the amount of the tax.
Do I pay Oklahoma tax on a car bought out of state?
Yes, if you live in Oklahoma. The excise and sales tax are due when you title it here, and the VIN inspection fee applies.
Does Oklahoma charge city sales tax on cars?
No. City and county sales taxes don't apply to the vehicle purchase. The excise tax and the 1.25% state vehicle sales tax are the only taxes.
What if my new car is stolen or turns out to be a lemon?
If a new vehicle is stolen within 90 days, or certified defective within six months, Oklahoma credits the excise tax and registration fee you paid against a new replacement vehicle.
