How Vehicle Excise Tax Works and What You Owe

A vehicle excise tax is a yearly tax on car ownership that your state or local government charges in addition to registration fees

A vehicle excise tax is a per-year tax based on the value of your car, truck, or motorcycle. It is separate from your registration fee and separate from sales tax — it is a tax you pay every year you own the vehicle. Some states call it a property tax on vehicles; some cities and counties charge it instead of or alongside the state. The amount you owe depends on what your vehicle is worth, and that value typically decreases each year, so your tax bill gets smaller as the car ages.

You usually pay it when you renew your vehicle registration, either as a single bill or as part of the registration paperwork. Some places let you pay it online; others require a check or in-person payment at the DMV or tax assessor's office. If you do not pay, your registration will not renew and you cannot legally drive the vehicle.

Key Takeaways

Vehicle excise tax is charged yearly based on your car's assessed value, not on how much you paid for it originally.
The tax amount decreases as your vehicle gets older because its assessed value drops each year.
You pay it at registration renewal time, and failure to pay will prevent your registration from renewing.
Only some states and localities charge vehicle excise tax; many states use only sales tax and registration fees instead.
The tax rate and calculation method vary widely by location, so what you owe depends on where you live and register your vehicle.

How the tax amount is calculated

The calculation starts with your vehicle's assessed value — an estimate of what the car is worth right now, not what you paid for it. Most states use a standard depreciation schedule: a new car loses value quickly in the first few years, then more slowly. The assessor applies a percentage rate (called the tax rate) to that assessed value to get your bill.

For example, if your car is assessed at $15,000 and your local tax rate is 1 percent, you would owe $150 for the year. If the same car is assessed at $10,000 the next year (because it is older), you would owe $100. The assessed value is usually set by your state's DMV or tax assessor's office based on the vehicle's age, make, model, and condition — not on what you actually paid.

Some places use a flat fee instead of a percentage. Others charge a higher rate on newer vehicles and a lower rate on older ones. A few states have no vehicle excise tax at all. You can find out your state's method by contacting your local tax assessor or DMV.

Which states and cities charge vehicle excise tax

Vehicle excise tax is not uniform across the United States. Some states rely on it heavily; others do not charge it at all. Massachusetts, Rhode Island, and Vermont are known for relatively high excise taxes. New Hampshire, Maine, and Connecticut charge it in some form. Many southern and western states do not have a state-level vehicle excise tax, though some cities or counties within those states may charge a local version.

Even within a state that has excise tax, the rate and rules can differ by county or municipality. A city might charge a local excise tax on top of the state tax, or a county might have its own assessment method. The best way to know what you owe is to check with your local tax assessor, DMV, or the town or county clerk's office where you register your vehicle.

When and how to pay your vehicle excise tax

You typically pay vehicle excise tax when you renew your vehicle registration. The bill arrives with your registration renewal notice, or you see the amount due when you go online to renew. Some states combine the excise tax and registration fee into one payment; others bill them separately.

Payment methods vary by location. Many states now allow online payment through the DMV website. Others require you to mail a check to the tax assessor's office or pay in person at the town hall, county assessor's office, or DMV. If you are unsure where to send payment, the renewal notice should say, or you can call your local tax assessor.

If you do not pay by the important date, your registration will not renew. This means you cannot legally drive the vehicle, and you may face penalties or late fees. Some places will not issue a new registration until the excise tax is paid in full.

How vehicle excise tax differs from registration fees and sales tax

These three are often confused because they all relate to vehicle ownership, but they are separate charges. Sales tax is a one-time tax you pay when you buy the car, based on the purchase price. Registration fees are yearly charges to keep your vehicle legally registered to drive on public roads — they are administrative fees, not a tax on value. Vehicle excise tax is a yearly tax on the current value of the car itself.

In a state with all three, you might pay sales tax at purchase, then every year you pay both a registration fee and an excise tax. In a state without excise tax, you pay sales tax at purchase and a registration fee each year, but no yearly value tax. Some states have excise tax but no sales tax on vehicles. The combination depends entirely on your state and local rules.

What happens if you do not pay vehicle excise tax

If you do not pay by the important date, your registration renewal will be blocked. You will not be able to renew your plates or get a new registration sticker. Driving with an expired registration is illegal and can result in a traffic citation and fine.

Late fees and interest may also accumulate on the unpaid tax. Some jurisdictions will place a lien on the vehicle or report the debt to a collection agency. If you are having trouble paying, contact your local tax assessor or town clerk to ask about payment plans or hardship options — many places offer them, though they are not may provide.

Frequently Asked Questions

Can I get a refund if I sell my car before the year is over?

Some states and localities offer a prorated refund if you sell the vehicle partway through the tax year, but policies vary widely. Contact your tax assessor or DMV to ask whether your location offers refunds and what paperwork you need to provide — usually a bill of sale or proof of transfer.

Is vehicle excise tax deductible on my income taxes?

Vehicle excise tax may be deductible as a state and local tax (SALT) on your federal income tax return, but rules change year to year and depend on your filing status and total deductions. Consult a tax professional or the IRS website to confirm whether you can deduct it in your situation.

What if I disagree with the assessed value of my car?

Most states allow you to appeal the assessed value if you believe it is too high. You typically file a formal appeal with your local assessor's office or board of appeals within a set window (often 30 to 60 days of receiving the bill). You may need to provide evidence such as a recent appraisal, comparable sales, or repair records showing the car is in poor condition.

Do I have to pay vehicle excise tax if I do not drive the car?

In most places, yes — the tax is based on ownership, not on whether you actually drive the vehicle. If you own a registered vehicle in a state or locality that charges excise tax, you owe it regardless of use. Some jurisdictions offer exemptions for vehicles that are not in operation, but you usually have to formally declare this with the assessor.
