The cheapest states to buy a car, measured purely by sales tax, are Alaska, Delaware, Montana, New Hampshire, and Oregon. None of them charge a state sales tax on vehicle purchases, which on a $35,000 car saves anywhere from $700 to more than $2,500 compared to a high-tax state. That is the clean answer for anyone who actually lives in one of those five states. For everyone else, the picture is more complicated, because dealer fees, registration costs, annual vehicle property taxes, and insurance premiums vary widely from state to state and often matter more over time than the sales tax rate you paid on day one.
The Five No-Sales-Tax States
Alaska, Delaware, Montana, New Hampshire, and Oregon impose no state-level sales tax. The purchase price at the dealership is the purchase price, with no percentage-based tax added on top.
Alaska comes with one caveat. It has no state sales tax, but some local municipalities charge their own, so the savings depend on which city the dealership sits in. The other four states have no local sales taxes that apply to vehicle purchases, so the zero-tax benefit holds statewide.
Why You Can’t Just Drive to Oregon and Save
Before planning a road trip to buy tax-free, understand how use tax works. Nearly every state with a sales tax also imposes a use tax at the same rate on vehicles brought in from out of state. Buy a car in Montana while living in a 6% state, and your home state will charge the full 6% when you register it locally.1Texas Comptroller of Public Accounts. Motor Vehicle Sales and Use Tax The purchase-state savings evaporate.
Most states offer a credit for any sales tax you already paid in the selling state. If you bought where the rate was 3% and your home state charges 6%, you owe the 3% difference at registration.2California DMV. Credit for Tax Paid to Another State The credit cannot exceed what your home state charges, so buying in a higher-tax state does not produce a refund. Buying out of state actually saves tax money only in two situations: you live in one of the five no-tax states, or the selling state’s rate is lower than your home state’s rate and you pocket the difference.
Lowest Sales Tax Rates If You’re Not in a No-Tax State
For residents of states that do charge sales tax, the rate itself is the biggest variable at purchase. A handful of states keep vehicle sales tax well below the national average:
- Alabama: 2% state rate, though local taxes can add significantly
- Colorado: 2.9% state rate
- North Carolina: 3% flat highway-use tax, capped at $2,000 on a vehicle purchase
- Hawaii: 4% general excise tax applied to vehicles
- Virginia: 4.15% motor vehicle sales tax
- Missouri: 4.225% state rate
On the other end, Nevada, Kansas, California, Indiana, Tennessee, and Rhode Island all have state rates at or above 7%, and local add-ons in some of these states push the effective rate past 9%. On a $30,000 car, the difference between Alabama’s 2% and a combined rate above 8% is roughly $1,800.
One detail trips people up. Some states apply the general sales tax rate to cars; others use a separate motor vehicle tax that differs from the standard rate. North Carolina, for example, charges its 3% highway-use tax rather than its standard 4.75% sales tax. Check the vehicle-specific rate, not the general one listed for the state.
Trade-In Credits
If you are trading in a vehicle, most states let you subtract the trade-in value before calculating sales tax. On a $40,000 purchase with a $12,000 trade-in, sales tax applies to $28,000 rather than the full price. At 6%, the trade-in credit saves $720.
A few states require sales tax on the full purchase price regardless of trade-in, which adds meaningfully to the bill. If you are weighing two states and plan to trade in, confirm whether the selling state allows the credit. The trade-in typically has to be part of the same transaction with the same dealer to qualify.
Dealer Documentation Fees
Dealer doc fees cover paperwork processing and go straight to the dealership, unrelated to any government tax. The spread across states is remarkable. Some states cap these fees by law; others let dealers charge whatever they want.
States with statutory caps keep the charge reasonable. California caps the fee at $70 for most dealers, or $85 for dealers who file electronically with the DMV.3California DMV. Dealer Document Preparation and Electronic Filing Service Fee New York caps at $175, Oregon at $200 without an integrator or $250 with one,4Oregon Public Law. ORS 822.043 Dealer Preparation and Submission of Documents and Minnesota at $350 for sales on or after July 2025.
In states without caps, the numbers climb fast. Florida dealerships routinely charge $999 to $1,295 per vehicle. Virginia dealers commonly bill $800 to $1,000. These fees are negotiable in theory, but dealers in uncapped states rarely budge because every customer pays the same inflated rate. The fee is usually buried in the buyer’s order, so read every line before signing. A $900 doc fee can wipe out the savings you fought for on the sticker price.
Registration and Title Fees
Every state charges fees to register a vehicle and issue a title, but the amounts differ enormously. Georgia, Kentucky, and Arkansas charge under $30 for basic registration. Tennessee and Ohio are also inexpensive, both under $35. At the high end, Mississippi charges over $700, Wyoming over $600, and Colorado close to $600 for registration alone.
These fees hit twice. You pay at first registration and again, sometimes at a reduced rate, every year at renewal. A state with a $500 annual registration fee costs $2,500 more over five years than one charging $50. For a car you plan to keep for a decade, that gap can rival the sales tax difference between states.
Some states base registration fees partly on the vehicle’s value, weight, or age, so a flat comparison misses details. A newer, heavier truck costs more to register in those states than an older sedan. Plug in your specific vehicle rather than relying on averages.
Annual Vehicle Property Taxes
Roughly half the states charge an annual personal property tax on vehicles, and this is the cost most buyers forget. About 25 states charge nothing at all, including Texas, Florida, Ohio, New York, Georgia, Illinois, Pennsylvania, and Oregon. Living in one of these states meaningfully lowers annual ownership cost.
Among states that do charge, rates range from trivial to painful. Louisiana’s effective rate sits around 0.1%, roughly $30 a year on a $29,000 car. Virginia has the highest effective vehicle tax rate in the country at nearly 4%, translating to over $1,100 per year on the same car. Mississippi, Missouri, and Maine all have effective rates above 2.4%.
This is where a state that looks cheap at the point of sale can turn expensive over time. New Hampshire charges no sales tax, saving money on day one, but its vehicle property tax rate of 1.8% means you pay roughly $524 per year on a $29,000 car for as long as you own it. After six or seven years, you have paid more in property tax than you saved by skipping sales tax. Kansas, Wyoming, and Colorado carry similarly high vehicle property tax rates that offset other savings.
Car Insurance Costs
Insurance is often the largest ongoing cost of car ownership, and it varies by state more than most people expect. Vermont has the lowest average annual premium at around $1,347, followed by Maine at about $1,515, New Hampshire near $1,520, and Ohio around $1,540. These states benefit from lower population density, fewer uninsured drivers, and less litigious legal environments that hold claims costs down.
At the top, Michigan, Louisiana, and Florida routinely see average annual premiums above $3,000. The gap between the cheapest and most expensive state for insurance can exceed $2,000 per year. Over a typical six-to-eight-year ownership period, that difference dwarfs any sales tax savings. Where you garage the car matters more for long-term cost than where you buy it.
Rates also depend heavily on the vehicle, your driving record, and your coverage levels. State averages give a baseline; your personal rate could land higher or lower.
If You Do Buy Out of State
If the math still points across a state line, the process adds a few steps. Bring a valid driver’s license, proof of insurance covering the new vehicle, and financing pre-approval if you are not paying cash. Have your insurer add the new car to your policy before you show up, or confirm they can bind coverage by phone from the dealer. Keep the original bill of sale. You will need it for your home state’s registration process, and it proves what you paid if the tax authority questions the amount.
Out-of-state buyers usually need a temporary transit tag to drive the car home legally. Dealerships typically handle this, but for a private-party purchase you may need to visit the selling state’s motor vehicle office yourself. The tag is valid for a limited time, often 30 days, and costs $5 to $50 depending on the state.5New Jersey Motor Vehicle Commission. Temporary Non-Resident Registration6Connecticut Department of Motor Vehicles. Get a Temporary Registration for In-Transit Vehicles Shipping the car home usually runs $500 to $1,500.
Once home, you generally have 30 to 90 days (varies by state) to register at your local motor vehicle office. Bring the signed title, bill of sale, proof of insurance, and payment for fees and taxes. Many states require a VIN inspection for a vehicle with an out-of-state title, where an official verifies the car matches the paperwork.7Arizona Department of Transportation. Vehicle Inspections8Ohio Bureau of Motor Vehicles. BMV Investigations You will pay any use tax owed, the title transfer fee, and registration. Some states also require an emissions test or safety inspection before issuing plates.
About eight states require vehicle titles to be notarized for a valid transfer: Arizona, Kentucky, Louisiana, Montana, Ohio, Oklahoma, North Carolina, and Pennsylvania. Dealers typically handle notarization at the sale. In a private-party transaction, both buyer and seller may need to sign in front of a notary.
Upfront Cheap vs. Long-Term Cheap
The cheapest state to buy a car depends on how long you plan to own it and which costs matter most. For pure upfront cost, the five no-sales-tax states are hard to beat if you actually live in one. For residents elsewhere, a combination of low sales tax, capped dealer fees, and inexpensive registration tends to produce the lowest transaction cost, and Midwest and parts of the South often come out ahead.
For long-term cost, the picture shifts. A state with moderate sales tax but no vehicle property tax, cheap registration renewals, and low insurance premiums will cost less over a decade than one where you saved $1,500 on sales tax but pay $500 a year in property tax and $2,800 a year to insure the car. Run the five-year and ten-year numbers for your own situation. The state where you register almost always matters more than the state where you buy.
