Maine car excise tax and registration fees

How the town excise is figured

The excise is the reason Maine car owners visit the town office every year. Under 36 M.R.S. §1482, the tax is a number of mills, thousandths of a dollar, applied to the maker’s list price of the model: 24 mills in the first year of the model, 17.5 in the second, 13.5 in the third, 10 in the fourth, 6.5 in the fifth and 4 mills from the sixth year onward, never less than $5. Two consequences follow. The price you negotiated does not matter, which is why the collector asks for the MSRP sticker of a new car. And an old car becomes cheap to keep: a 2021 model bought privately for $18,000 is already at the 4-mill rate, which the calculator puts at $72 when it uses that price.

Sales tax on a car, dealer or private

Maine applies its ordinary 5.5% sales and use tax to vehicles. A car traded toward another car is subtracted first, so only the difference is taxed. The dealer’s documentation fee is not: Maine Revenue Services counts processing and documentation fees as part of the taxable sale price, and no Maine law caps them, so read that line before signing. A sale between two private parties is taxed too; the buyer pays the 5.5% when registering, on the price declared.

Inspection, Cumberland County and the yearly budget

Every registered car needs a safety inspection once a year. Stations may charge at most $12.50, or $18.50 for the enhanced inspection with an onboard diagnostics check that Cumberland County requires for 1996 and newer models. A car bought from a dealer must already carry a sticker issued within 60 days of the sale, so you usually pay the first inspection a year later. For a state with a comparable town-and-state split but different rates, see the New Hampshire page, or compare yearly costs across states with the car ownership cost calculator.

What sets Maine apart

• Maine's yearly car tax is a municipal excise paid to your town before the state registers the car, set by statute at 24 mills per dollar of the maker's list price in the model's first year (36 M.R.S. §1482).
• The excise rate falls with the model year: 17.5 mills in the second year, 13.5 in the third, 10 in the fourth, 6.5 in the fifth and 4 mills from the sixth year on, with a $5 minimum (36 M.R.S. §1482).
• Because the excise follows the list price and not the price paid, a dealer discount does not lower it; buyers of a new car hand the MSRP sticker to the excise collector (36 M.R.S. §1482).
• The state sales and use tax is 5.5% of the price, the same general rate as other goods (36 M.R.S. §1811).
• When a car is traded toward another car, the 5.5% applies only to the difference between the price and the trade-in allowance (36 M.R.S. §1765).
• A private sale of a car is not exempt: Maine levies its tax on casual sales of motor vehicles (36 M.R.S. §1764).
• Maine Revenue Services treats dealer processing and documentation fees as part of the taxable sale price (Maine Revenue Services).
• A one-year automobile registration costs $35, and a certificate of title costs $33 (29-A M.R.S. §501).
• Every registered car needs a yearly inspection; stations may charge at most $12.50, or $18.50 for the enhanced inspection required in Cumberland County (29-A M.R.S. §1751).
• Maine has no electric or hybrid registration surcharge in its registration fee statute; an automobile pays the same $35 whatever its fuel (29-A M.R.S. §501).

What the Maine calculation cannot know

• The municipal excise tax is based on the maker's list price (MSRP) of the model, not the price paid; when the MSRP is not typed, the engine uses the price, which understates the excise of a discounted new car and of any used car.
• Inspection amounts are the legal maximum fees of 29-A M.R.S. §1751 ($12.50, or $18.50 for the enhanced inspection required in Cumberland County); a station may charge less.
• Municipalities can add a small agent fee when the town office processes the registration; it varies by town and is not added.
• No dealer documentation fee cap exists in Maine law (a 2023 bill to limit the fee, LD 639, died); type the dealer's fee. It is taxed at 5.5% as part of the sale price.
• On a private sale the 5.5% use tax is computed on the price declared; the engine does not check it against a book value.
