Behind the numbers
How Oklahoma tag, title and tax is worked out
Oklahoma charges a motor vehicle excise tax instead of regular sales tax on a vehicle: 3.25% of the purchase price for a new vehicle, and for a used vehicle $20 on the first $1,500 of value plus 3.25% of the rest. The title fee is a flat $11. The annual registration fee depends on the vehicle's age and falls as the car gets older.
New $20,000 vehicle, 3 years old: 3.25% × $20,000 ($650.00) + $11 + $96 (years 1–4) = $757. Used $20,000 vehicle, 3 years old: $20 + 3.25% × $18,500 ($621.25) + $11 + $96 = $728.25.
Oklahoma registration fee by vehicle age
Registration is an annual fee; the excise tax and title fee are one-time charges when the vehicle is first titled. A separate 1.25% state sales tax also applies to the purchase price and is not included in the total above.
A few comparisons
Example tag, title and tax
| Vehicle | Excise tax | Registration | Total |
|---|---|---|---|
| New, $20,000, 3 years old | $650.00 | $96 | $757.00 |
| Used, $20,000, 3 years old | $621.25 | $96 | $728.25 |
| New, $30,000, 6 years old | $975.00 | $86 | $1,072.00 |
| Used, $8,000, 10 years old | $231.25 | $66 | $308.25 |
| Used, $1,200, 18 years old | $20.00 | $26 | $57.00 |
All totals above include the $11 title fee. The used-car excise tax is always a little lower than the new-car rate on the same price, because the first $1,500 is taxed at a flat $20 instead of 3.25%.
Before you go to the tag agency
This is an estimate — fees are set by the Oklahoma Tax Commission and Service Oklahoma and can change, so confirm the exact amount with Service Oklahoma or a licensed operator before you pay.
Budget for the separate 1.25% state sales tax on top of the total above — on a $20,000 vehicle that is another $250.00, and it is charged on the full purchase price.
On a used vehicle the excise tax is $20 on the first $1,500 plus 3.25% of the rest, so a cheaper used car pays noticeably less tax than a new car at the same price.
Extra charges may apply on top of the total here, such as a $17 transfer fee when ownership changes, a tire recycling fee, or a VIN inspection fee — and registering late can add a penalty.
Good to know
Your Oklahoma tag, title and tax questions, answered.
How is the excise tax calculated on a used car in Oklahoma?
A used vehicle is taxed $20 on the first $1,500 of its value, plus 3.25% of the value above $1,500. For a used $20,000 vehicle that is $20 + 3.25% of $18,500 = $621.25. A new vehicle is simpler: a flat 3.25% of the full purchase price.
Why is registration cheaper for an older car?
Oklahoma's annual registration fee falls as the vehicle ages: $96 a year in years 1-4, $86 in years 5-8, $66 in years 9-12, $46 in years 13-16, and $26 a year from year 17 on. A 3-year-old car costs $96 a year to register, while the same car at 18 years old costs $26.
Is the 1.25% sales tax included in this total?
No. Oklahoma also charges a separate 1.25% state sales tax on a vehicle purchase, on top of the excise tax. On a $20,000 vehicle that is another $250.00. The total above covers only the excise tax, the $11 title fee and the registration fee, so budget for the sales tax as well.
Is this the exact amount I will pay?
No, it is an estimate. The figures are the current published rates — 3.25% excise tax, an $11 title fee and the age-based registration schedule — but fees are set by the Oklahoma Tax Commission and Service Oklahoma and can change. Extra charges such as a $17 transfer fee, a tire fee or a VIN inspection fee may also apply, so confirm the exact amount with Service Oklahoma or a licensed operator before you go.
