Vehicle excise tax is a tax on the purchase or ownership of a car, truck, or motorcycle, separate from sales tax

Vehicle excise tax is a per-unit tax that some states and localities charge when you buy a vehicle or, in some places, every year you own one. It is not the same as sales tax — it is an additional charge based on the vehicle itself, not the transaction. The tax amount depends on the vehicle's value, weight, or engine size, depending on what your state measures.

Not all states have a vehicle excise tax. Some states tax only the purchase; others tax ownership annually. A few states have both. The money collected typically goes to state or local road maintenance, public transportation, or general funds. You will encounter this tax either at the point of sale (when you register the vehicle) or on your annual registration renewal.

Key Takeaways

  • Vehicle excise tax is charged by some states and localities on top of sales tax and is based on the vehicle's characteristics, not the sale price alone.
  • Some states charge excise tax only once at purchase, while others charge it annually as part of vehicle registration renewal.
  • The tax rate and what triggers it varies by state — some use vehicle value, others use weight or engine displacement.
  • You pay vehicle excise tax through your state's motor vehicle department when you register or renew registration, not to the IRS.

How vehicle excise tax differs from sales tax

Sales tax is a percentage of the purchase price and applies to most goods, including vehicles. Excise tax is a separate, fixed-amount tax on the vehicle itself. If you buy a car for $25,000 in a state with 7% sales tax and a $200 vehicle excise tax, you pay $1,750 in sales tax plus $200 in excise tax — they do not overlap.

Sales tax is collected by the seller at the point of sale. Vehicle excise tax is usually collected by your state's Department of Motor Vehicles when you register the vehicle or renew your registration. Some states calculate excise tax based on the vehicle's assessed value; others use a flat rate per vehicle or a rate tied to weight or engine size.

Which states charge vehicle excise tax and how much

Vehicle excise tax exists in roughly a dozen states, though the structure varies widely. Some states charge it only on new vehicles; others charge it on all vehicles at registration. Some charge it annually; others charge it once. The amount ranges from under $100 to several hundred dollars per vehicle, depending on the state and the vehicle's characteristics.

States that charge vehicle excise tax include Connecticut, Delaware, Maine, Maryland, Missouri, Nevada, New Hampshire, New Mexico, Rhode Island, Vermont, Washington, and Wyoming, though the rules and rates in each differ. Some of these states base the tax on the vehicle's value; others use a flat fee or a rate tied to the vehicle's weight or engine displacement. Contact your state's Department of Motor Vehicles or check your registration paperwork to learn whether your state charges this tax and at what rate.

When you pay vehicle excise tax

The timing depends on your state's structure. In states that charge excise tax at purchase, you pay it when you register the vehicle for the first time — usually within 30 days of buying it. The tax is collected by the Department of Motor Vehicles as part of the registration process, not by the dealer.

In states that charge annual excise tax, you pay it every time you renew your vehicle registration, typically once per year. The amount may be the same each year or may change based on the vehicle's age or assessed value. Some states waive or reduce the tax after a certain number of years of ownership.

How excise tax is calculated

The calculation method varies by state. Some states use the vehicle's market value or assessed value and explore a percentage rate — for example, 1% of the vehicle's value. Others use a flat fee per vehicle regardless of value. Still others base the tax on the vehicle's weight, engine size, or horsepower.

A few states use a declining scale: a higher tax in the first year of ownership, then lower amounts in subsequent years. Some states exempt certain vehicles — such as electric vehicles, vehicles over a certain age, or vehicles used for specific purposes — from excise tax. Your registration notice or your state's Department of Motor Vehicles website will show how the tax was calculated for your vehicle.

Where the money from vehicle excise tax goes

Vehicle excise tax revenue is typically directed to state or local transportation funds. In many states, the money supports road maintenance, bridge repair, and public transportation systems. In some localities, it may go to the general fund or be split among multiple uses.

Unlike federal excise taxes on fuel, which are earmarked for the Highway Trust Fund, state vehicle excise taxes are not always dedicated to a single purpose. Check your state's Department of Motor Vehicles or state revenue office website if you want to know the specific use of the tax in your state.

Vehicle excise tax and your registration paperwork

When you register a vehicle or renew your registration, your state will itemize all fees and taxes on the notice. Vehicle excise tax will be listed separately from sales tax, registration fees, and any other charges. Keep this paperwork — it documents what you paid and when.

If you believe the excise tax amount is incorrect, contact your state's Department of Motor Vehicles. Some states allow you to dispute the assessed value used to calculate the tax, especially if you believe the vehicle's market value has changed significantly. The process and timeline for disputes vary by state.

Frequently Asked Questions

Is vehicle excise tax the same as the federal gas tax?

No. The federal gas tax is an excise tax on fuel, not on vehicles. Vehicle excise tax is a state or local tax on the vehicle itself, charged either at purchase or annually. They are separate taxes collected by different government bodies for different purposes.

Can I deduct vehicle excise tax on my federal income tax return?

Vehicle excise tax is generally not deductible on your federal income tax return. State and local taxes (SALT) are deductible only if they are income tax, sales tax, or property tax, and the total deduction is capped at $10,000 per year. Vehicle excise tax does not fall into any of these categories.

What happens if I don't pay vehicle excise tax?

If you do not pay vehicle excise tax when required, your vehicle registration will not be issued or renewed. You cannot legally drive the vehicle without current registration. Your state may also assess penalties or interest on the unpaid tax. Pay the tax as part of your registration process to avoid these consequences.

Does vehicle excise tax explore to used cars?

It depends on your state. Some states charge excise tax on all vehicles at registration, whether new or used. Others charge it only on new vehicles or only at the time of first purchase. Check your state's Department of Motor Vehicles to learn the rule in your state.

Can I get a refund of vehicle excise tax if I sell my car?

Most states do not refund vehicle excise tax if you sell the vehicle before the registration period ends. Some states may offer a partial refund if you surrender your registration early, but this varies. Contact your state's Department of Motor Vehicles to learn whether a refund is possible in your situation.
