Registering a car in Maine typically costs between $35 and $500 or more, with the final amount heavily dependent on your vehicle's MSRP (Manufacturer's Suggested Retail Price) and age. The primary cost is the state's excise tax, which is a municipal tax based on your car's value. The registration fee itself is a standard $35 for most passenger vehicles. The entire process is handled through your local town office, not a state-level DMV.
The core of the cost is Maine's unique excise tax. It's calculated as a mill rate on your vehicle's assessed value. The assessed value is determined by the MSRP and then depreciated on a set schedule. The mill rate varies by municipality but is applied uniformly.
| Vehicle Age (Model Year) | Standard Valuation (as % of Original MSRP) | Excise Tax per $1,000 of MSRP (at a sample 15-mill rate) |
|---|
| Current Year (New) | 100% | $15.00 |
| 2nd Year | 90% | $13.50 |
| 3rd Year | 80% | $12.00 |
| 4th Year | 70% | $10.50 |
| 5th Year | 60% | $9.00 |
| 6th Year and Older | 50% | $7.50 |
For example, registering a 3-year-old car with an original MSRP of $30,000 in a town with a 15-mill rate would cost: Assessed Value = $30,000 x 80% = $24,000. Excise Tax = ($24,000 / 1,000) x 15 mills = $360. Add the $35 registration fee, and your total due would be approximately $395.
Additional fees can include a $33 title fee if you're transferring a title, and plate fees if you need new ones. Some towns may also charge small agent fees. Vehicles over 25 years old may qualify for a lower, fixed antique auto registration fee. The best way to get an exact quote is to contact your local town office with your Vehicle Identification Number (VIN).
