What car excise tax is
Excise tax on a car is a state or local tax on vehicle ownership itself, separate from sales tax. You pay it once a year (or sometimes twice), based on the value of the vehicle you own. It is not a tax on driving, fuel, or registration — it is a tax on the fact that you own the car.
The tax rate and the value used to calculate it vary by state and sometimes by county. Some states tax the full market value of your car; others use a depreciation schedule that lowers the taxable value each year. A few states do not have an excise tax at all. The amount you owe can range from under $100 to several hundred dollars annually, depending on where you live and what you own.
Excise tax bills usually arrive with your vehicle registration renewal notice, and payment is often required before you can renew your registration. Some states let you pay it online; others require a check or in-person payment at the town or county assessor's office.
Key Takeaways
- Excise tax is an annual tax on vehicle ownership, not on driving or fuel, and is separate from sales tax and registration fees.
- The tax rate and how your car's value is calculated depend on your state and sometimes your county, so the amount you owe varies widely.
- Excise tax bills typically arrive with your registration renewal notice, and you must pay before you can renew your registration.
- Some states phase out the tax after a certain number of years of ownership, while others tax the vehicle for its entire life.
- If you move to a different state, you may owe excise tax in your new state even if your old state did not have one.
How the tax is calculated
The calculation starts with your car's value. Some states use the manufacturer's suggested retail price (MSRP) or the car's market value at the time of purchase. Others use a depreciation schedule — a formula that reduces the taxable value each year the car gets older. A car worth $30,000 new might be taxed on $25,000 in year two, $20,000 in year three, and so on.
Once the taxable value is set, the state or local tax rate is applied. This rate can be a flat percentage (for example, 1.5% of value) or a tiered system where older or less expensive cars pay a lower rate. Some municipalities add a local excise tax on top of the state rate, which is why two people in the same state can owe different amounts.
A few states use a different method entirely — they base the tax on the vehicle's weight, engine size, or a fixed fee per vehicle rather than on value. Check your state's tax authority website or your most recent registration bill to see which method applies to you.
Which states have excise tax and which do not
About half of U.S. states impose some form of excise tax on vehicles. States that do include Massachusetts, Rhode Island, Connecticut, Vermont, New Hampshire, and several others. The tax structure, rate, and how long you pay it vary significantly from state to state.
States without an excise tax include California, Texas, Florida, New York, and many others. If your state does not have an excise tax, you will not owe one — but you may still owe sales tax at purchase and registration fees each year.
If you move from a state with excise tax to one without, you stop paying it. If you move the opposite direction, you will begin paying excise tax in your new state, usually starting with your first registration renewal there.
How excise tax differs from other car taxes and fees
Sales tax is a one-time tax paid when you buy the car, based on the purchase price. Excise tax is an annual tax on ownership. Registration fees are charges for the right to drive the car on public roads and typically cover administrative costs. Property tax (in states that impose it on vehicles) is similar to excise tax but may use different valuation methods.
Some states combine these into a single bill at registration time, so it can be hard to see which part is which. Your registration notice should break down the charges. If it does not, contact your state's Department of Motor Vehicles or your local assessor's office and ask for an itemized bill.
Fuel tax is another separate charge — it is collected at the pump and goes toward road maintenance. You pay it every time you fill up, not once a year like excise tax.
When you start and stop paying excise tax
You typically begin paying excise tax the year after you buy the car, when you renew your registration for the first time. Some states start the tax immediately upon purchase; others give you a grace period. Check your state's rules to know when your first bill will arrive.
How long you pay depends on your state. Some states tax vehicles for their entire lifespan — a 20-year-old car still owes excise tax. Others phase it out after 10, 15, or 20 years of ownership. A few states eliminate the tax once a car reaches a certain age (for example, 15 years old) or a certain model year. This is one reason to check your state's specific rules rather than assume based on what a neighbor pays.
If you sell the car, you stop owing excise tax in that state. If you trade it in, the new owner (or the dealer) becomes responsible for the tax on the new vehicle.
What happens if you do not pay excise tax
Excise tax is usually a requirement for vehicle registration renewal. If you do not pay, your registration will not be renewed, and you cannot legally drive the car on public roads. Driving with an expired registration can result in a traffic citation and fines.
If you fall behind on excise tax payments, your state may add penalties and interest to the bill. Some states will place a lien on the vehicle, which can complicate a sale or trade-in. A few states may suspend your driver's license if excise tax debt goes unpaid for an extended period, though this is less common than registration suspension.
If you believe your tax bill is incorrect — for example, if the assessed value is wrong — you can file an appeal with your local assessor's office. The process and deadline vary by state, so act quickly if you think there is an error.
How to find out what you owe
Your excise tax bill arrives with your vehicle registration renewal notice, usually a few weeks before your registration expires. If you have not received a bill and your registration is about to expire, contact your state's Department of Motor Vehicles or your local town or county assessor's office.
You can also check online if your state offers a motor vehicle tax lookup tool. Most state DMV websites have a section where you can enter your vehicle identification number (VIN) or license plate and see what you owe. Some states allow you to pay online; others require payment by mail or in person.
If you are buying a used car, ask the seller or dealer whether there are any unpaid excise taxes on it. In some states, unpaid excise tax can transfer to the new owner, so it is worth confirming before you complete the purchase.
Frequently Asked Questions
Do I have to pay excise tax if I own a car but do not drive it?
Yes. Excise tax is based on ownership, not on use. If you own the vehicle and it is registered in your name, you owe the tax regardless of whether you drive it, keep it in storage, or let it sit in your driveway. The only way to stop owing it is to sell the car or transfer the title to someone else.
Can I deduct excise tax on my income tax return?
Excise tax is generally not deductible on your federal income tax return. However, some states allow a deduction on state income tax for vehicle-related taxes. Check your state's tax rules or speak with a tax professional about what may apply to you.
What if I buy a car late in the year — do I owe a full year of excise tax?
This depends on your state. Some states prorate the tax based on when you register the vehicle, so you might owe only a few months. Others charge a full year's tax regardless of when you buy. Check your state's DMV website or call your local assessor to find out how your state handles mid-year purchases.
Does excise tax apply to electric vehicles or hybrids?
Most states tax electric and hybrid vehicles the same way they tax gas-powered cars — based on value or other standard methods. However, a few states offer a tax break or exemption for electric vehicles as an incentive to buy them. Check your state's rules if you own or are considering an EV.
What if I move and my new state has a different excise tax rate?
When you register your car in the new state, you will owe excise tax according to that state's rules and rates. You will not owe tax to your old state once you have transferred your registration. The new state's tax is based on the car's current value or the state's depreciation schedule, not on what you paid in your previous state.
