A car excise tax is a yearly tax on vehicle ownership, separate from sales tax

A car excise tax is an annual tax you pay to own a vehicle, calculated as a percentage of the car's value. It is not the same as sales tax (which you pay once when you buy the car) or registration fees (which cover the cost of your license plate). Instead, excise tax is a recurring tax that most states and many municipalities charge every year you keep the vehicle registered.

The tax amount depends on your car's assessed value, which usually declines each year as the vehicle ages. A new car worth $30,000 will have a higher excise tax than the same model five years later. Some states use the manufacturer's list price; others use the actual sale price or a depreciation schedule they set by law.

Not all states charge a car excise tax. Those that do include Massachusetts, Rhode Island, Connecticut, Illinois, Ohio, and several others. Some states charge it only in certain counties or cities. If you live in a state or area that does charge it, you typically pay when you renew your vehicle registration, and the amount appears on your registration bill.

Key Takeaways

  • Car excise tax is an annual ownership tax based on your vehicle's value, not a one-time purchase tax.
  • The tax rate and calculation method vary by state and sometimes by city or county within a state.
  • Your car's assessed value usually decreases each year, so your excise tax bill typically goes down over time.
  • You pay excise tax when you renew your registration, and it appears as a separate line item on your bill.
  • Some states do not charge an excise tax at all, so check your state's Department of Motor Vehicles website to confirm whether you owe one.

How the tax is calculated and what your bill includes

The calculation starts with your car's assessed value. In most states, this value is not what you paid for the car or what it would sell for today. Instead, the state uses a formula that begins with the manufacturer's suggested retail price (MSRP) or the actual sale price, then applies a depreciation schedule. A car loses value fastest in its first year, so the assessed value drops sharply from year one to year two, then more slowly after that.

Once the state sets the assessed value, it multiplies that number by the excise tax rate. Tax rates vary widely: Massachusetts charges roughly 0.5% to 1% of assessed value per year, while other states may charge 1% to 2% or use a different formula altogether. Some states have a flat fee per vehicle instead of a percentage. A few states cap the tax at a maximum amount, so even if your car is very expensive, you never pay above that ceiling.

Your excise tax bill arrives as part of your vehicle registration renewal notice. The bill will show the assessed value, the tax rate, and the total amount due. If you pay your registration online or by mail, the excise tax is included in the total. Some states allow you to pay excise tax separately from registration, but most bundle them together.

Which states and cities charge a car excise tax

Car excise tax is not universal. The following states currently charge it statewide: Connecticut, Illinois, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Missouri, New Hampshire, Ohio, Rhode Island, Tennessee, Vermont, and Washington, D.C. However, the rate, calculation method, and exemptions differ in each place.

Some states charge excise tax only in certain counties or cities. For example, in some states, only municipalities have the power to levy it, so you may owe it in one town but not in another. A few states allow local governments to opt in or out. This means your excise tax bill depends not just on your state but on exactly where your vehicle is registered.

The best way to find out whether you owe a car excise tax is to visit your state's Department of Motor Vehicles website or contact your local town or city assessor's office. They can tell you the rate, the assessed value formula used in your area, and when payment is due. If you move to a new state or register a vehicle in a new county, the excise tax rules may change.

How excise tax differs from registration fees and sales tax

Car excise tax, registration fees, and sales tax are three separate charges, and it is straightforward to confuse them. Sales tax is a one-time tax you pay when you buy the car, calculated as a percentage of the purchase price. It goes to the state and sometimes to the city. You pay it once, at the point of sale, and it does not appear on your registration bill.

Registration fees are charges you pay to register your vehicle with the state and receive a license plate. These fees cover the cost of issuing and maintaining the registration system. They are usually a flat amount or a small amount based on vehicle weight or type. Like excise tax, you pay registration fees every year when you renew, and they appear on your registration bill.

Excise tax is an annual tax on ownership, based on the car's value. It is separate from both sales tax and registration fees. A single registration bill may include all three: the registration fee, the excise tax, and sometimes a sales tax or use tax if you recently purchased the vehicle. Reading your bill carefully will show you which charges are which.

What happens if you do not pay your car excise tax

If you do not pay your excise tax by the due date, penalties and interest begin to accumulate. Most states add a late fee (often 10% to 20% of the unpaid tax) and monthly or daily interest. The longer you wait, the larger the total bill becomes. Some states charge compound interest, meaning interest accrues on top of interest.

If excise tax remains unpaid for several months or longer, the state may suspend your vehicle registration or driver's license. This means you cannot legally drive the car or renew your registration until you pay the tax and any penalties. In some cases, the state may place a lien on the vehicle, which means they have a legal claim against it and can seize it to cover the debt.

If you cannot pay the full amount at once, contact your state's Department of Motor Vehicles or your local assessor's office to ask about payment plans. Many states allow you to pay in installments, especially if you have a legitimate hardship. Paying even a partial amount on time can reduce the penalties and show good faith.

Exemptions and reductions for certain vehicles

Some vehicles are exempt from excise tax in certain states. Common exemptions include vehicles owned by the military, vehicles used for farming or commercial purposes, vehicles owned by nonprofit organizations, and vehicles registered to people over a certain age (usually 65 or older). A few states exempt electric vehicles or hybrid vehicles to encourage clean energy adoption, though these exemptions sometimes expire after a set number of years.

Exemptions vary significantly by state and sometimes by municipality. A vehicle that is exempt in one town may not be exempt in another. To find out whether your vehicle qualifies for an exemption, contact your local assessor or your state's Department of Motor Vehicles. You will usually need to file a form or provide documentation to claim the exemption, and you may need to renew it each year.

Some states offer a reduction in excise tax for vehicles that are very old, have very high mileage, or have been damaged in an accident. These reductions are usually not automatic; you have to request them and provide proof. The amount of the reduction depends on the state's rules and the condition of the vehicle.

How to find out your car excise tax amount

Your excise tax bill arrives with your vehicle registration renewal notice, usually in the mail or online through your state's DMV portal. The notice will show the assessed value, the tax rate, and the total amount due. If you want to know the amount before the bill arrives, you can contact your local assessor's office or your state's Department of Motor Vehicles and provide your vehicle identification number (VIN) and registration information.

Many states now allow you to look up your excise tax online. Visit your state's DMV website and look for a tool to check your registration status or tax amount. You will typically need your VIN, license plate number, or registration number. Some municipalities also post excise tax information on their assessor's office website.

If you believe your assessed value is incorrect, you can file a formal appeal with your local assessor. The process and important date for appeals vary by state, but you usually have 30 to 60 days from the date you receive your bill. You may need to provide evidence that your car is worth less than the state's assessed value, such as a recent appraisal or sale price documentation.

Frequently Asked Questions

Do I have to pay car excise tax if I own the car outright?

Yes. Excise tax is based on vehicle ownership, not on whether you have a loan or own the car free and clear. If your name is on the registration, you owe the tax. The lender or bank does not pay it for you.

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

No. The federal government does not allow a deduction for car excise tax on your personal income tax return. However, if you use the vehicle for business purposes, you may be able to deduct it as a business expense. Consult a tax professional about your specific situation.

What if I sell my car partway through the year?

This depends on your state's rules. Some states prorate the excise tax, meaning you pay only for the months you owned the car and the new owner pays for the remaining months. Others do not prorate, and the person who owns the car on the assessment date owes the full year's tax. Check your state's DMV website or contact your assessor to learn how your state handles this.

Is excise tax the same as property tax on a vehicle?

They are related but not identical. Excise tax is a tax on the privilege of owning a vehicle, while property tax is a tax on the value of property you own. Some states use the terms interchangeably, but the calculation and rules may differ. Check your state's definition to be sure which one you owe.

What if I move to a state that does not charge excise tax?

When you register your vehicle in the new state, you will no longer owe excise tax there. However, you may owe it in your old state for the remainder of the year if you have not yet paid it. Contact your old state's DMV to confirm whether you still owe anything before you leave.
