Five states charge no general sales tax on car purchases: Alaska, Delaware, Montana, New Hampshire, and Oregon. That’s the short answer, and it’s the one most people are looking for. The longer answer is that “no sales tax” doesn’t always mean “no tax.” Four of the five collect something else on vehicles, and if you live in a state that does charge sales tax, driving across a border to buy a car almost never lets you keep the difference.
What Each of the Five States Actually Charges
Only one of these states is genuinely tax-free at the point of purchase. The others collect a document fee, a privilege tax, a local sales tax, or a registration-based tax that functions much like one.
Delaware
Delaware charges a 5.25% document fee on the purchase price or NADA book value, whichever is higher, with a minimum of $8.1Delaware DMV. Fees – Division of Motor Vehicles That rate is higher than the vehicle sales tax in roughly a dozen states. Calling Delaware a no-sales-tax state for cars is technically accurate; in practice, buyers pay a percentage of the vehicle’s value that works almost identically to sales tax.
Oregon
Oregon added a 0.5% vehicle privilege tax in 2018 that applies to new or nearly-new vehicles purchased from a dealer, defined as those with 7,500 miles or fewer on the odometer.2Oregon.gov. Vehicle Privilege and Use Taxes On a $40,000 car, that’s $200. Used cars over the mileage threshold are exempt, and so are sales to non-residents. For a used private-party purchase, Oregon is genuinely tax-free.
Alaska
Alaska has no state-level sales tax, but local boroughs and municipalities can impose their own. Anchorage, Juneau, Kenai, Ketchikan, and Kodiak are among the areas that do.3Alaska DMV. Motor Vehicle Registration Tax Chart Rates and structures vary. If you live in or buy from a taxable area, you’ll owe a motor vehicle registration tax collected by the DMV. Senior citizens, disabled veterans, and active-duty military may qualify for exemptions.
Montana
Montana charges no sales tax but collects registration fees pegged to the vehicle’s age: $217 for zero to four years old, $87 for five to ten years, and $28 for eleven years and older.4Montana Motor Vehicle Division. Light Vehicle Registration and Fees Counties can also impose an optional tax based on the manufacturer’s suggested retail price, depreciated over time. On a brand-new vehicle the county option tax can start at up to 100% of MSRP and drops each year on a set schedule. The combined cost is still well below traditional sales tax in most cases, but it isn’t zero.
New Hampshire
New Hampshire has no sales tax and no vehicle-specific purchase tax. Registration is a two-part process with fees paid to both the state and the local town or city.5New Hampshire Division of Motor Vehicles.

Why Buying in a No-Tax State Usually Doesn’t Save You Anything
This is where most cross-border car-shopping plans fall apart. If you live in a state that charges sales tax and you buy a car in one that doesn’t, your home state will collect a use tax when you register the vehicle. The use tax rate matches your state’s sales tax rate, and you pay it at the DMV before you get plates. You end up paying the same amount you would have paid at a dealership down the street.
Nearly every state with a sales tax also imposes a use tax for exactly this reason. The tax follows the vehicle’s registration address, not the purchase location. If your state’s rate is 6%, you’ll owe 6% whether the car came from Oregon, Delaware, or a private seller two states over.
Buying out of state can reduce your bill only when you’ve already paid some tax in the purchase state. Most states credit sales or use tax paid elsewhere, so you’d owe only the difference between the two rates. Pay 4% in one state, owe 6% at home, and you settle the remaining 2% at registration. Buying in a state with no tax at all means no credit, and the full home-state rate applies.
The Military Exception
Active-duty service members get real protection under the Servicemembers Civil Relief Act. Federal law provides that a service member’s personal property, including vehicles, cannot be taxed by a state solely because the service member is stationed there, and the SCRA’s definition of taxation specifically includes fees and excises on motor vehicles.6Office of the Law Revision Counsel. 50 USC 4001 – Taxes Respecting Personal Property, Money, Credits, and Intangibles
In practice, if you’re stationed in a state with a 7% vehicle sales tax but your legal domicile is a state with no sales tax or a lower rate, you can’t be forced to pay the higher rate. You pay based on your home of record. Many service members deliberately maintain domicile in New Hampshire, Montana, or Alaska for this reason. Some states also allow military buyers to defer payment until they leave active duty or return to the state, though the specifics vary.
Ways to Actually Reduce the Tax You Owe
Since geography rarely helps, the real savings on car sales tax come from what’s taxed, not where. Two mechanisms matter.
A trade-in usually reduces the taxable amount. On a $35,000 car with a $12,000 trade-in, most states calculate tax on the $23,000 difference rather than the full sticker price. At a 6% rate, that’s $720 saved. A handful of states either disallow the credit or cap it, so confirm with your state’s DMV or revenue department before assuming it applies.
Manufacturer rebates typically work the same way when applied directly to the purchase price. Dealer incentives passed through to the buyer generally reduce the taxable total as well. A cash rebate mailed to you after the sale usually doesn’t, because the dealer collects tax on the full amount at closing.
Private Sales and Gifts
Sales tax doesn’t disappear when you buy from a private seller. The buyer is responsible for paying it at the DMV during title transfer and registration. A dealership handles collection and remittance; in a private sale, you write the check yourself.
How states value the sale varies. Some tax whatever price the buyer and seller agree on. Others use fair market value or book value, whichever is higher, specifically to keep buyers from writing a low number on the bill of sale.
Gifts are treated differently in different states. Several exempt gifts between family members from sales tax or charge only a nominal flat fee. Others tax the vehicle’s fair market value even when no money changes hands. The recipient’s home state controls the answer.
