How Massachusetts Excise Tax Works and When You Owe It
What the Massachusetts excise tax is and who pays it
Massachusetts excise tax is a yearly tax on vehicles registered in the state. It is not the same as your car insurance or registration fee — it is a separate bill that arrives once a year from your city or town assessor's office. The tax is based on the value of your vehicle, and the amount you owe depends on what your car, truck, or motorcycle is worth according to state valuation tables.
You owe excise tax if you own a vehicle registered in Massachusetts, even if you do not drive it regularly. The tax applies to cars, trucks, motorcycles, and some recreational vehicles. If you own the vehicle on October 1 of any year, you will receive a bill for the following fiscal year (which runs July 1 to June 30 in Massachusetts).
The tax is paid to your local city or town, not to the state directly. Each municipality collects and keeps the money, so the bill comes from your assessor's office, and payment goes to your town treasurer or tax collector.
Key Takeaways
- Massachusetts excise tax is an annual vehicle tax based on your car's value, billed by your city or town assessor's office.
- The bill arrives once a year and covers the fiscal year from July 1 to June 30; you owe tax if you owned the vehicle on October 1 of the prior year.
- You can pay by check, online through your town's website, or in person at the tax collector's office, and payment deadlines vary by municipality.
- If you sell your vehicle or move out of state, you may be able to get a refund or credit for the unused portion of the tax year.
- Late payments trigger interest charges and can eventually lead to a tax lien on your vehicle, preventing registration renewal.
How the excise tax amount is calculated
The state of Massachusetts publishes a valuation guide each year that assigns a value to every make, model, and year of vehicle. Your town assessor uses this guide to determine what your specific car is worth, then applies the local tax rate to that value. The tax rate varies by town but is typically between $10 and $15 per $1,000 of vehicle value.
For example, if your 2019 Honda Civic is valued at $15,000 according to the state guide, and your town's tax rate is $12.50 per $1,000 of value, your excise tax would be $187.50. A newer or more expensive vehicle will have a higher bill; an older vehicle will have a lower one. The valuation decreases each year as the vehicle ages, so your excise tax bill typically goes down over time.
You cannot negotiate the valuation or the tax rate. If you believe the state's valuation of your vehicle is wrong, you can file an abatement request with your assessor's office, but this is uncommon and requires documentation that your car is worth significantly less than the guide value.
When and how to pay your excise tax bill
Your excise tax bill arrives by mail, usually between August and October, for the fiscal year that begins July 1. The due date is set by your town and is typically in November or December, but this varies. Check your bill for the exact due date, or contact your town tax collector's office if you are unsure.
Most towns accept payment by check mailed to the tax collector's office, by credit or debit card through the town's online payment portal, or in person at the tax collector's office during business hours. Some towns also accept payment by phone or through third-party payment services. Visit your town's website or call the tax collector to find out which methods are available.
Pay on time to avoid interest charges. Massachusetts law allows towns to charge interest on late excise tax payments, typically at a rate set by the state (which changes annually). Interest begins to accrue immediately after the due date, so even a few days late will result in additional charges on top of the original bill.
What happens if you do not pay on time
If your excise tax bill is not paid by the due date, your town will send you a notice of the late payment and the interest owed. You still have time to pay without serious consequences at this stage — simply send the full amount (original tax plus interest) to your tax collector.
If you ignore the notice and do not pay for several months, your town can file a tax lien against your vehicle. This lien prevents you from renewing your vehicle registration with the Registry of Motor Vehicles. When you try to renew your registration online or in person, the system will flag the lien and deny the renewal until the tax and interest are paid in full.
In rare cases, if the debt remains unpaid for an extended period, the town may pursue collection through a collection agency or small claims court. This can damage your credit and result in wage garnishment or bank account levies. The best course of action is to contact your tax collector as soon as you know you cannot pay by the due date and ask about payment plans or hardship options.
Refunds and credits for vehicle sales or moves
If you sell your vehicle before the end of the fiscal year (June 30), you may be may have access to to a refund of the unused portion of your excise tax. For example, if you paid tax for the full year but sold the car in March, you would receive a refund for the four months remaining (April through June).
To receive a refund, you must provide your tax collector with proof of sale, such as a bill of sale or the title transfer document showing the new owner's name and the sale date. Submit this documentation to your assessor's office or tax collector's office. The refund is usually processed within a few weeks and sent by check or applied as a credit to any other taxes you owe to the town.
If you move out of Massachusetts and no longer register your vehicle in the state, you can also request a refund for the unused portion of the tax year. You will need to provide proof of out-of-state registration or a bill of sale showing the vehicle was sold or transferred. The same process applies: submit documentation to your tax collector and wait for the refund to be processed.
Excise tax for new vehicle purchases
When you buy a new vehicle and register it in Massachusetts for the first time, you will owe excise tax for the remainder of that fiscal year, calculated on a prorated basis. If you register a new car in January, you will owe tax for January through June (six months), not the full year. The bill will arrive with your registration paperwork or shortly after.
The amount is based on the purchase price of the vehicle if it is brand new, or the state valuation guide if it is used. If you buy a used car, the assessor will use the guide value for that make, model, and year, not the price you paid. This means you might pay more or less excise tax than you expected based on what you actually spent.
Keep your registration paperwork and the bill together so you know when payment is due. Some people miss the excise tax bill because they expect it to arrive with the registration renewal notice, which comes later in the year.
Hardship options and payment plans
If you cannot pay your excise tax bill in full by the due date, contact your town tax collector immediately. Many towns have the authority to set up a payment plan that allows you to pay the tax in installments over several months. The town may also charge a small fee for the payment plan, and interest will continue to accrue on the unpaid balance.
Some towns may also offer a temporary deferral or extension if you can demonstrate financial hardship, though this is not may provide and depends on your town's policies. The tax collector's office is the best source for information about what options are available in your municipality. Do not wait until after the due date to ask — contact them as soon as you know you will have trouble paying.
If you are a senior citizen or disabled, your town may offer a property tax exemption or deferral program that could reduce or postpone your excise tax bill. These programs vary widely by town, so check with your assessor's office to see what is available where you live.
Frequently Asked Questions
Can I get an excise tax abatement if my car is worth less than the state valuation?
You can file an abatement request with your assessor's office if you believe the state valuation is significantly wrong. You will need to provide evidence, such as recent repair estimates showing major damage, or a professional appraisal. Most abatement requests are denied, but it is worth trying if your vehicle is in poor condition or has been in an accident.
What if I inherit a vehicle — do I owe excise tax?
Yes, if you own the vehicle on October 1, you will owe excise tax for the following fiscal year. If you inherit a car late in the year and sell it before October 1, you may avoid the tax. If you inherit it before October 1, register it in your name and expect a bill the following summer.
Do I owe excise tax if my vehicle is registered but not driven?
Yes. Excise tax is based on ownership and registration, not on whether you actually drive the vehicle. If it is registered in Massachusetts in your name on October 1, you owe tax for that fiscal year, even if the car sits in a garage unused.
Can I pay excise tax online, and is there a fee?
Most Massachusetts towns now offer online payment through their websites. Some charge a small convenience fee (usually 2 to 3 percent) if you pay by credit card, but payment by bank transfer or check is typically free. Check your town's tax collector website to see what methods are available.
What happens if I move to another state — do I still owe Massachusetts excise tax?
If you own the vehicle on October 1 and are still registered in Massachusetts, you owe tax for that fiscal year even if you move later. Once you register the vehicle in your new state and provide proof to your Massachusetts tax collector, you can request a refund for the unused portion of the tax year.
