An excise tax on a car is a tax on the purchase or ownership of the vehicle itself, separate from sales tax

An excise tax is a per-unit tax that some states charge on new or used vehicles at the time of purchase. Unlike sales tax, which is a percentage of the purchase price, an excise tax is often a flat fee or a smaller percentage that goes directly to the state or local government. The amount you pay depends on where you live, what type of vehicle you're buying, and sometimes the vehicle's weight or engine size.

Not every state has an excise tax on cars. Some states use only sales tax, some use excise tax alone, and some use both. If your state has one, you'll typically pay it when you register the vehicle or at the time of purchase, depending on how that state structures the tax.

Key Takeaways

  • An excise tax is a flat fee or small percentage charged on vehicle purchases in certain states, separate from sales tax.
  • The amount varies by state and may depend on the vehicle type, weight, or engine size rather than just the purchase price.
  • You pay excise tax at purchase or registration, depending on your state's rules.
  • Some states have no excise tax on cars, while others charge it on new vehicles, used vehicles, or both.
  • Excise tax revenue typically funds state transportation, roads, or environmental programs.

How excise tax differs from sales tax

Sales tax is a percentage of what you pay for the car. If you buy a $30,000 vehicle in a state with 7% sales tax, you pay $2,100 in sales tax. An excise tax, by contrast, is usually a flat amount or a smaller percentage that doesn't scale with the purchase price.

For example, some states charge a flat excise tax of $50 or $100 per vehicle, regardless of whether you're buying a $15,000 used sedan or a $80,000 new truck. Other states tie the excise tax to the vehicle's weight or engine displacement, so a heavier vehicle or one with a larger engine costs more to tax. A few states charge a small percentage—say 2%—as an excise tax in addition to the regular sales tax.

The key difference is that excise taxes are designed to target a specific product (vehicles) for a specific purpose, while sales tax is a general revenue tool that applies to most goods.

Which states have excise taxes on cars

Excise tax rules vary widely. Some states that have historically charged excise taxes on vehicles include Washington, Vermont, and Maine, though the structure and amount differ in each. Some states charge excise tax only on new vehicles, while others charge it on used vehicles or both. A few states have phased out or modified their excise taxes in recent years.

Because these rules change and vary by state, the best way to find out whether your state charges an excise tax is to check your state's Department of Motor Vehicles website or contact your local DMV office directly. When you're ready to register a vehicle, the registration paperwork will show all taxes owed, including any excise tax.

What the excise tax money funds

States use excise tax revenue for different purposes depending on state law. Many states direct the money toward road maintenance and transportation infrastructure. Some use it to fund environmental programs, such as emissions testing or electric vehicle incentives. A few states use excise tax revenue for general state operations.

Understanding where the money goes can help you see why your state charges the tax, though the tax amount itself is set by state law and not something you can negotiate or avoid at purchase time.

When you pay the excise tax

The timing depends on your state. In some states, you pay the excise tax at the dealership or point of sale, and it appears on your bill of sale. In others, you pay it when you register the vehicle with the DMV, either online or in person. A few states allow you to pay it at the time of registration renewal each year.

If you're buying from a dealer, ask them whether the excise tax is included in the quoted price or added at checkout. If you're buying from a private seller, contact your state's DMV to find out when and how to pay the excise tax during registration.

Excise tax on electric vehicles and hybrids

Some states offer reduced excise taxes or exemptions for electric vehicles or hybrid vehicles as an incentive to buy cleaner cars. For example, a state might charge the full excise tax on a gas-powered sedan but a lower rate or no excise tax on an electric vehicle. These incentives change over time and vary by state.

If you're considering an electric or hybrid vehicle, check your state's current rules before purchase. The savings from a reduced excise tax can add up, especially on a higher-priced vehicle. Your dealer or state DMV can tell you whether the vehicle you're interested in qualifies for a reduced rate.

Excise tax on used vehicles

Whether you pay excise tax on a used vehicle depends on your state's rules. Some states charge excise tax on all vehicles, new or used. Others charge it only on new vehicles. A few states charge a lower excise tax on used vehicles or base it on the vehicle's age or current market value rather than the original purchase price.

When you buy a used car from a private seller or a used-car dealer, the excise tax is typically paid at registration, not at the point of sale. The DMV will calculate what you owe based on the vehicle's details and your state's excise tax rules.

Frequently Asked Questions

Is excise tax the same as registration fees?

No. Registration fees are what you pay to register the vehicle with the DMV each year. Excise tax is a one-time or annual tax on the vehicle itself. Some states charge both, and they appear as separate line items on your registration bill.

Can I deduct excise tax on my income taxes?

Excise tax on a personal vehicle is not deductible on your federal income tax return. If you use the vehicle for business, you may be able to deduct vehicle expenses under different rules, but the excise tax itself is not a separate deduction.

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

If you don't pay the excise tax when required, your vehicle registration may not be processed or may be suspended. You could face penalties or fines. Pay the excise tax as part of your registration to avoid registration delays.

Does excise tax explore to motorcycles or RVs?

It depends on your state. Some states charge excise tax on all motor vehicles, including motorcycles and RVs. Others exempt certain vehicle types. Check your state's DMV website or call to find out whether the specific vehicle you're buying is subject to excise tax.

Can I get a refund if I sell the car?

Most states do not refund excise tax if you sell the vehicle. The tax is paid once at purchase or registration and is not prorated or returned. Check your state's rules, as a few states may have different policies.
