Overview
For a used vehicle, the first $1,500 of value owes a flat $20 in excise tax instead of a percentage - only the amount above $1,500 gets the 3.25% rate. The 1.25% sales tax, by contrast, applies to every dollar of price with no threshold. This calculator runs both taxes correctly for new or used vehicles so you're not guessing which number the licensed operator will actually charge.

Oklahoma car sales tax FAQ
How much tax will I pay on a $10,000 used car in Oklahoma?
$401.25 total: excise tax of $276.25 ($20 flat on the first $1,500 + 3.25% of the remaining $8,500) plus sales tax of $125 (1.25% of $10,000). A new $10,000 vehicle would owe $450 instead - the full 4.5% with no $1,500 break.
Why is my excise tax bill lower than 3.25% of the price?
Only on used vehicles, and only because the first $1,500 of value is taxed at a flat $20 rather than a percentage. On a $3,000 used car that's $20 plus 3.25% of $1,500 ($48.75) = $68.75 excise tax - well under a straight 3.25% of $3,000 ($97.50).
Does Oklahoma still give a trade-in tax credit?
Not as of July 1, 2026. House Bill 1183 rewrote the value definition used for excise tax to be simply "the actual sales price" on the bill of sale and removed the older statutory language permitting discounts or trade-in credits to reduce that price. This changed very recently - verify the current treatment with your licensed operator before assuming a trade-in will lower your bill.
Is the 1.25% sales tax based on the same value as the excise tax?
No - that's the trap. The $20-on-first-$1,500 formula is an excise-tax-only rule. The 1.25% sales tax is calculated on the entire purchase price with no threshold, whether the car is new or used.
Do gifted vehicles owe this tax?
A qualifying family gift - spouse to spouse, or parent/stepparent to child/stepchild, with no money changing hands - owes neither tax if you file the Family Affidavit (Form 794). A gift outside that narrow relationship list still owes excise tax on the vehicle's assessed value, though it escapes the 1.25% sales tax since no sale actually occurred.
Are any vehicles fully exempt from both taxes?
Yes: vehicles for qualifying disabled veterans, transfers by court order in a divorce, transfers into or out of certain trusts without consideration, and government/tribal purchases. Ordinary private-party and dealer sales don't qualify no matter how low the agreed price.
