What is the Massachusetts Used Car Excise Tax?
The Massachusetts motor vehicle excise is an annual tax for the privilege of registering a motor vehicle in the Commonwealth of Massachusetts. It is not a property tax. The tax is levied by the city or town where the vehicle is principally garaged. If you want to calculate Massachusetts excise tax for a used car, it’s important to understand that the calculation is based on the vehicle’s original value, not its current market value or the price you paid.
This tax applies to all vehicles registered in the state, and the revenue generated helps fund local community services. The excise is calculated at a standard rate, but the vehicle’s taxable value decreases each year according to a fixed depreciation schedule set by the state.
Used Car Excise Tax Formula and Explanation
The formula to calculate the motor vehicle excise is straightforward. It is based on the vehicle’s value, which is a percentage of the original Manufacturer’s Suggested Retail Price (MSRP). The excise rate is fixed at $25 per $1,000 of the vehicle’s assessed value.
The formula is:
Excise Tax = (Original MSRP * Valuation Percentage) / 1000 * $25
The key is determining the correct valuation percentage, which depends on the age of the vehicle. Our MA car tax calculator above does this for you automatically.
Variables Table
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Original MSRP | The manufacturer’s suggested retail price when the car was new. | USD ($) | $10,000 – $100,000+ |
| Valuation Percentage | A percentage set by law, based on the vehicle’s age. | Percent (%) | 10% – 90% |
| Assessed Value | The taxable value after applying the valuation percentage to the MSRP. | USD ($) | Varies based on MSRP and age. |
| Excise Rate | The fixed rate set by the Commonwealth of Massachusetts. | Rate | $25 per $1,000 of value |
Massachusetts Excise Tax Depreciation Schedule
The value of a vehicle for excise tax purposes is depreciated over its first five years. After the fifth year, the value remains fixed at 10% of the original MSRP for all subsequent years. Understanding this schedule is essential to accurately calculate Massachusetts excise tax for a used car.
| Vehicle’s Year | Valuation (% of Original MSRP) |
|---|---|
| In the year of manufacture | 90% |
| In its second year | 60% |
| In its third year | 40% |
| In its fourth year | 25% |
| In its fifth year and onwards | 10% |
Practical Examples
Example 1: A 3-Year-Old Car
Let’s say you have a used car with a model year of 2023 and an original MSRP of $30,000. In 2026, the car is in its third year.
- Inputs: Original MSRP = $30,000, Model Year = 2023.
- Calculation:
- Valuation Percentage (Third Year): 40%
- Assessed Value: $30,000 * 40% = $12,000
- Excise Tax: ($12,000 / 1000) * $25 = $300.00
- Result: The estimated annual excise tax is $300.00.
Example 2: An Older Car
Now, consider an older used car with a model year of 2018 and an original MSRP of $22,000. For more information on vehicle registration, see our guide on vehicle registration.
- Inputs: Original MSRP = $22,000, Model Year = 2018.
- Calculation:
- The car is more than five years old, so the valuation is capped at 10%.
- Assessed Value: $22,000 * 10% = $2,200
- Excise Tax: ($2,200 / 1000) * $25 = $55.00
- Result: The estimated annual excise tax is $55.00.

Key Factors That Affect Your Excise Tax
Several factors influence the final amount on your excise tax bill. If you’re looking for professional tax help, see our tax consulting services.
- Original MSRP: The starting point of the calculation. A higher original MSRP leads to a higher tax, even for an older used car.
- Vehicle Age: The single most important factor for a used car. The tax decreases significantly during the first five years.
- Tax Rate: The rate is fixed by state law at $25 per $1,000 of value. This is consistent across all towns and cities.
- Proration: If you register a vehicle partway through the year, your excise will be prorated for the number of months it is registered.
- Minimum Tax: There is a minimum motor vehicle excise of $5.00. If your calculated tax is less than this, you will be billed $5.00.
- Place of Garaging: The bill is sent by the municipality where the vehicle is primarily kept, which determines where the tax revenue goes.
Frequently Asked Questions (FAQ)

2. What’s the lowest my excise tax can be?
The minimum annual excise tax is $5.00.
3. Why is my older car’s tax not decreasing anymore?
After the fifth year, a vehicle’s value for excise purposes bottoms out at 10% of its original MSRP and does not decrease further.
4. Does the condition of my car affect the tax?
No. The condition, mileage, or market value of the vehicle are not considered in the excise tax calculation.

Your excise tax will be prorated. You will be billed for the full month you registered in, plus all the remaining months in the calendar year.
6. Can I get a discount or abatement on my excise tax?
Abatements are typically granted if you sell the vehicle, trade it in, or move out of Massachusetts. You must apply for an abatement with your local assessors’ office; it is not automatic. Learn more about local governance in our post about understanding property taxes.
