Sources & Methodology
Methodology: Excise tax = max((MSRP / 1000) x rate, $25 minimum). Official Maine rates by year: Year 1 = $24.00/1,000, Year 2 = $17.50/1,000, Year 3 = $13.50/1,000, Year 4 = $10.00/1,000, Year 5 = $6.50/1,000, Year 6+ = $4.00/1,000. Maine sales tax = purchase price x 5.5%. Total first-year cost = excise tax + sales tax + registration fee. Annual savings = Year 1 excise - Year 2 excise. 5-year total = sum of years 1-5 excise tax. All calculations based on Title 36 MRSA Section 1482 and current Maine Revenue Services guidance.

Maine Excise Tax Calculator -- Complete Guide to Maine Vehicle Taxes
Maine's vehicle excise tax is an annual property tax collected by municipalities when you register your vehicle. Unlike most states that tax vehicles based on purchase price or current market value, Maine calculates excise tax using the vehicle's original MSRP and decreases the rate each year the vehicle ages. Understanding how Maine excise tax is calculated helps you budget for vehicle ownership costs and evaluate the true total cost of buying a new versus used vehicle in Maine.
Maine Excise Tax Rate Schedule -- Official 2025 Rates
Maine excise tax rates are set by Title 36 MRSA Section 1482 and have not changed significantly in recent years. The rate is applied per $1,000 of the vehicle's original MSRP, not the purchase price you paid.
| Vehicle Year | Rate per $1,000 MSRP | $25K MSRP | $35K MSRP | $50K MSRP |
|---|
| Year 1 | $24.00 | $600 | $840 | $1,200 |
| Year 2 | $17.50 | $437.50 | $612.50 | $875 |
| Year 3 | $13.50 | $337.50 | $472.50 | $675 |
| Year 4 | $10.00 | $250 | $350 | $500 |

Maine Sales Tax on Vehicle Purchases
Maine charges a 5.5% sales tax on the purchase price of vehicles at dealers and on private party sales registered in Maine. For a $30,000 vehicle, the sales tax is $1,650. The sales tax is separate from excise tax and is paid once at the time of purchase -- it is not an annual charge. Private party vehicle sales in Maine are subject to the same 5.5% sales tax, which is collected by the town office at the time of registration transfer.
Unlike some states, Maine does not allow a trade-in credit to reduce the taxable sale price for sales tax purposes. The full purchase price is taxable regardless of any trade-in.
New Car vs Used Car -- Maine Excise Tax Comparison
One frequently overlooked advantage of buying a used vehicle in Maine is the lower excise tax. A 3-year-old used car with an original MSRP of $35,000 already pays at the Year 3 rate ($472.50) versus Year 1 ($840) for a new car with the same MSRP. Over 5 years, the total excise tax on a $35,000 MSRP vehicle amounts to approximately $2,500 -- with most of that cost concentrated in the first two years. Buying a vehicle that is already 3 to 4 years old can save $400 to $600 in excise tax in the first year of ownership alone.
Where and When to Pay Maine Excise Tax
Maine excise tax is collected by your local municipal office (town office or city hall) -- not the state directly. You must pay excise tax before the Secretary of State will issue registration plates. Registration renewals are typically due in the month of your birthday. If you register a vehicle mid-year, the excise tax is prorated for the remaining months of the registration period. You will need to bring your vehicle title or registration certificate, proof of insurance, and payment to the town office.
💡 Pro tip -- MSRP vs purchase price: Maine excise tax is based on original MSRP, not what you paid. If you negotiated a $5,000 discount on a $40,000 MSRP vehicle, your excise tax is still calculated on $40,000 -- not $35,000. For Year 1, that means paying $24 x 40 = $960 instead of $840. When comparing vehicles, always check the original window sticker MSRP, not just the asking price, to accurately budget your annual excise tax obligation.
Frequently Asked Questions
How is Maine excise tax calculated? +
Maine excise tax is calculated by dividing the vehicle MSRP by 1,000 and multiplying by the applicable rate for the vehicle year: $24.00 in Year 1, $17.50 in Year 2, $13.50 in Year 3, $10.00 in Year 4, $6.50 in Year 5, and $4.00 in Year 6 and beyond. The minimum excise tax is $25 per year regardless of vehicle age or calculated amount. The tax is paid annually at your local town office when you register or renew vehicle registration.
How much is Maine excise tax on a new car? +
Maine excise tax on a new car in its first year is $24.00 per $1,000 of MSRP. A $35,000 MSRP vehicle would owe $840 in Year 1. A $50,000 MSRP vehicle would owe $1,200 in Year 1. The rate drops to $17.50 per $1,000 in Year 2, then continues to decrease annually until reaching $4.00 per $1,000 in Year 6 and beyond. Excise tax is paid annually at your town office at registration renewal.
Is Maine excise tax based on MSRP or purchase price? +
Maine excise tax is based on the original MSRP (Manufacturer Suggested Retail Price) from the factory window sticker, not the purchase price you paid or the current market value. Even if you bought the vehicle at a discount, received a trade-in, or purchased a used vehicle below MSRP, the excise tax calculation uses the original factory MSRP. This is defined in Title 36 MRSA Section 1482.
Does Maine excise tax decrease every year? +
Yes. Maine excise tax decreases each year as the vehicle ages through the rate schedule. Starting at $24.00 per $1,000 MSRP in Year 1, the rate steps down through $17.50, $13.50, $10.00, and $6.50 before reaching the minimum rate of $4.00 per $1,000 in Year 6 and beyond. The $4.00 rate applies indefinitely after Year 6. The minimum tax of $25 applies if the calculated amount falls below $25.
Is there a Maine sales tax on vehicle purchases? +
Yes. Maine charges a 5.5% sales tax on vehicle purchases at dealers and on private party sales registered in Maine. For a $30,000 purchase price the sales tax is $1,650. Sales tax is paid once at time of purchase or registration transfer, separate from the annual excise tax. Maine does not allow a trade-in credit to reduce the taxable sale price.
Do I pay Maine excise tax every year? +
Yes. Maine excise tax is paid annually when you register or renew vehicle registration at your local town office. The tax is due at registration renewal, typically in your birthday month in Maine.

What is the minimum Maine excise tax? +
The minimum Maine excise tax is $25 per year. This applies when the calculated excise tax falls below $25, which typically occurs for older vehicles with low original MSRP values.
