What Massachusetts excise tax is and who owes it
Excise tax is an annual tax on vehicle ownership in Massachusetts. Every car, truck, motorcycle, and RV registered in the state incurs this tax. The Registry of Motor Vehicles (RMV) assesses it based on the vehicle's value, and the tax bill goes to your city or town assessor's office, not to the state directly.
You owe excise tax for the year you register a vehicle and for each year you keep it registered. The amount depends on the vehicle's value according to the RMV's valuation schedule. A new car pays more than an older one with the same model year. If you sell or trade in the vehicle partway through the tax year, you may be able to get a refund for the unused portion, but you must request it from your assessor.
The bill arrives by mail from your local assessor's office, usually in the fall for the following calendar year. The due date varies by town but is typically in December or January. If you do not pay by the deadline, your town can place a lien on the vehicle, and you cannot renew your registration until the tax is paid.
Key Takeaways
- Excise tax bills come from your city or town assessor, not from the state, and the due date depends on where you live.
- You can pay in person at the assessor's office, by mail, online through your town's website, or by phone if your town offers it.
- The bill shows the vehicle's assessed value, the tax rate, and the total amount due; keep your receipt as proof of payment.
- If you sell the vehicle during the tax year, contact your assessor to request a refund for the months you no longer owned it.
- Unpaid excise tax prevents vehicle registration renewal and can result in a lien on the vehicle.
Where to send your payment
Your excise tax bill lists the assessor's office address and payment instructions for your specific town. Do not send payment to the state; it goes to your local assessor. The bill itself usually shows whether your town accepts online payment, mail, or in-person payment at the office.
Call your town assessor's office directly to confirm the current payment address and accepted methods. Many towns now accept online payment through their municipal websites or through third-party payment processors. Some towns allow phone payment by credit or debit card. Paying in person at the assessor's office during business hours is always an option and gives you an immediate receipt.
If you cannot locate your bill, contact the assessor's office with your vehicle's registration number or VIN. They can tell you the amount owed and the due date. Do not assume the bill was not sent; bills sometimes arrive late or go to an old address if you moved.
Payment methods and timing
Most Massachusetts towns accept payment by check, money order, or cash in person. Many now also accept credit cards, debit cards, or electronic bank transfers online. A few towns allow payment by phone. The method available to you depends on your town's system.
If you pay by mail, send the check or money order at least one week before the due date to account for postal delays. Include the bill stub or a note with your vehicle's registration number and VIN so the assessor can match the payment to your account. If you pay online, the payment usually posts within one to three business days. In-person and phone payments are typically recorded immediately.
Keep your receipt or confirmation number. If you pay online, print or save the confirmation page. If you pay by mail, keep a copy of the check or money order number. These prove you paid on time if a question arises later.
What happens if you miss the due date
If the tax remains unpaid after the due date, your town assessor will send a notice. Most towns add a penalty and interest to the original amount. The penalty is typically 10 to 14 percent of the tax owed, and interest accrues monthly on the total.
After a set period (usually 30 to 90 days past due, depending on the town), the assessor can file a lien against the vehicle. A lien means the town has a legal claim on the vehicle until the tax is paid. You cannot renew your vehicle registration with the RMV if a lien is in place. The RMV's system is connected to the assessor's records, and the registration renewal will be blocked.
If the tax remains unpaid for a longer period, the town may pursue collection through a tax collector or attorney. Contact your assessor immediately if you cannot pay by the due date to discuss a payment plan or hardship options. Some towns offer payment arrangements for taxpayers facing financial difficulty.
Refunds for vehicles sold or removed from service
If you sell or trade in your vehicle before the tax year ends, you may be may have access to to a refund for the months you no longer owned it. The refund is calculated based on the number of months remaining in the tax year after the sale or removal date.
To request a refund, contact your assessor's office with proof of the sale or removal. Proof can be a bill of sale, a trade-in receipt, or a letter from the dealer. Some towns require a form to be completed. The assessor will calculate the refund amount and issue it by check, usually within four to eight weeks.
Do not assume the refund will happen automatically. You must file the request. If you do not request a refund and the vehicle is no longer registered in your name, you may still be billed for the full year's tax, and collecting the refund later becomes more difficult.
Understanding your excise tax bill
Your bill shows several pieces of information: the vehicle's assessed value according to the RMV, the tax rate per thousand dollars of value (set by your town), the total tax amount, and the due date. The bill also lists the assessor's office address and payment instructions.
The assessed value on the bill may differ from what you paid for the vehicle or what you think it is worth. The RMV uses a standardized valuation schedule based on the vehicle's model year, make, and model. This schedule is updated annually. If you believe the assessed value is incorrect, you can appeal it to your assessor's office, but this must be done before the tax year begins. Once the bill is issued, the value is locked in for that year.
The tax rate varies by town. A town's rate is set by its board of selectmen or city council and is applied to all vehicles registered there. Two identical vehicles in different towns will have different tax amounts because of the different rates.
Frequently Asked Questions
Can I pay my excise tax online?
Many Massachusetts towns offer online payment through their municipal websites or third-party payment systems. Check your bill for the payment website, or call your assessor's office to ask if online payment is available in your town. If it is, you will usually need your bill number or VIN to set up the payment.
What if I moved and did not receive my bill?
Contact your assessor's office and provide your current address. Ask them to mail a new bill or confirm the amount owed. If you moved out of state or sold the vehicle, tell the assessor so they can update their records. You are still responsible for the tax even if you did not receive the bill.
Can I pay in installments?
Most towns require full payment by the due date. However, if you cannot pay in full, contact your assessor's office to ask about a payment plan. Some towns offer arrangements for hardship cases, though this is not may provide. The sooner you contact them, the better your options.
Do I owe excise tax if my vehicle is registered out of state?
No. Excise tax is owed only on vehicles registered in Massachusetts. If your vehicle is registered in another state, you do not owe Massachusetts excise tax, even if you live in Massachusetts and drive it here.
What if the assessor's office says I already paid but I still see a bill?
Bring your receipt or confirmation number to the assessor's office in person, or send a copy by mail. There may be a delay in the system updating, or the payment may have been recorded under a different name or account number. The assessor can verify the payment and issue a corrected bill or confirmation letter.
