Used-car sales tax runs from no general sales tax in five states (Alaska, Delaware, Montana, New Hampshire and Oregon) to over 8% in some states once local rates stack, and you pay the rate of the state where you register the car, not where you buy it. This guide ranks every state, calls out the buyer-friendly outliers, and explains the trade-in credit rules most buyers do not know exist.
Calculator defaults to a $12,000 price with no trade-in and no local rate. Estimates only. Also available as the standalone Vehicle Sales Tax Calculator, and each state has its own dedicated page.

The Five No-Sales-Tax States
Five states charge no general sales tax on vehicle purchases:
- Alaska — but boroughs and cities can add up to 7.5% local
- Delaware — charges a 4.25% Document Fee that functions like a sales tax
- Montana — true zero. Popular for out-of-state LLC registration (where allowed)
- New Hampshire — true zero. Most buyer-friendly state for used car costs
- Oregon — 0.5% Vehicle Privilege Tax on dealer sales (often passed to buyer)

Trade-In Credit: The Detail Most Buyers Miss
Most states reduce your taxable basis by your trade-in value. A few do not. The difference is meaningful.
Example: $20,000 car, $5,000 trade-in, 6.25% sales tax:
- With trade-in credit: Taxable amount $15,000 → tax $938
- Without trade-in credit: Taxable amount $20,000 → tax $1,250
- Savings from credit: $312
States WITHOUT trade-in credit on used cars:
- California
- Hawaii
- Kentucky (uses standard schedule, not credit-based)
- Maryland
- Michigan (capped at $9,000 trade-in value, indexed annually)
- Mississippi (limited)
- North Carolina (uses HUT, no trade-in concept)
- Oklahoma
- South Carolina (uses IMF cap)
- Virginia
If you live in one of these states and have a trade-in, the math is meaningfully worse than for buyers in trade-in-credit states.
Special Cases
Georgia (TAVT)
Georgia replaced sales tax on vehicles with a 7% Title Ad Valorem Tax (TAVT). It applies to the fair market value of the vehicle, not the purchase price. So buying under-market doesn't help you. The state DMV maintains a value table they use for the basis.
North Carolina (Highway Use Tax)
NC charges a 3% Highway Use Tax instead of sales tax. The tax is capped for some vehicle categories, so check the current cap with NCDMV. No local additions. No trade-in credit.
South Carolina (IMF Cap)
South Carolina caps its Infrastructure Maintenance Fee at $500 on vehicles. This means high-priced vehicles get a significant break — a $50,000 truck pays the same $500 IMF as a $11,000 sedan. Buyer-friendly for expensive vehicles.
Iowa (One-Time Registration Fee)
Iowa charges a 5% one-time registration fee at the time of purchase, functionally identical to sales tax in other states.
Delaware (Document Fee)
Delaware charges 4.25% "Document Fee" at registration. Functionally a sales tax even though officially not.
The Out-of-State Buyer Question
Can you buy in a no-sales-tax state and avoid the tax? Generally no.
The default rule: you pay sales tax based on where you register the vehicle, not where you buy it. So a New Yorker buying a car in New Hampshire still owes NY sales tax when registering at the NY DMV.
Three exceptions where the math sometimes works:
-
Montana LLC — buy through a Montana LLC, register the car in Montana, get Montana plates. Whether it holds up depends on your home state, which may still treat you as the taxpayer.
-
Genuine relocation — if you actually move to a no-tax state, register there.
-
Bona fide non-resident purchaser — if you live elsewhere, the dealer may not collect your home state's tax (you owe it yourself at registration).
The Montana LLC route is fraught: your home state can still claim the tax if you actually live and drive there. Consult a CPA before pursuing it.

Open the calculatorHow Local Tax Stacks the Bill
Local sales tax (county, city, transit district) is layered on top of state rate in most states. Combined rates can dramatically exceed the base state rate:
- Texas: 6.25% state, with no local additions on vehicles.
- California: 7.25% state, with district taxes added on top that differ by city and county.
- Tennessee: 7% state, with local additions on top (see the table above).
- Louisiana: 4.45% state, with local parish rates stacked on top.
When evaluating where to buy, check both state AND local rate.
For Flippers: Why This Matters
Sales tax does not directly affect you when buying inventory (you generally do not pay it on flips). But it MASSIVELY affects what your buyers will pay:
- A buyer in California pays the state rate plus local district tax on top of your asking price
- A buyer in Oregon pays no sales tax
- The same asking price produces a higher out-the-door (OTD) total in a high-tax state than in a zero-tax state
Buyers shop by OTD price, not asking price. Your asking price in a high-tax market must implicitly account for buyers' total cost tolerance. Markets with lower tax rates often support slightly higher asking prices because the OTD-equivalent ceiling is higher.
CarFlipIQ tracks median asking prices by state, which already reflects this dynamic. See used car prices by state.
Bottom Line
Used car sales tax starts at 0% in five states and rises once local rates stack. State rate, local rate, trade-in credit rules, and special-case taxes (NC HUT, GA TAVT, SC IMF) all shift the math.
