Do You Pay Taxes When You Buy a Car From a Private Seller in Massachusetts?

When you buy a car and register it in the state of Massachusetts, you owe sales tax—whether you’re buying from a dealer or a private seller. The sales tax on vehicles in Massachusetts currently stands at 6.25% of the purchase price. For example, if you buy a used car from a private party for $10,000, you’ll pay $625 in sales tax.

Unlike many other states across the US, Massachusetts does not allow local governments to collect sales taxes. The applicable sales tax rate is the same no matter where you live in the Bay State. No additional taxes are levied by cities and counties.

Sales or use tax on motor vehicles and trailers must be paid by the 20th day of the month after their purchase, use, storage, or other consumption within the state. If you (the buyer) don’t pay the sales or use tax on time, you will have to pay interest and penalties.

In addition to the sales tax, other fees involved with purchasing a used car may include registration fees, title fees, and documentation fees.

Check the Massachusetts Department of Revenue website for further information on sales and use tax responsibilities.

How is Used Car Sales Tax Calculated in Massachusetts?

Sales taxes are assessed as a percentage of the vehicle’s purchase price. Some people think they’ll outsmart the state by negotiating a low “official” purchase price and paying the remainder in a side transaction. The Massachusetts Department of Motor Vehicles (DMV) is way ahead of you.

People who try to avoid paying the full vehicle tax by artificially lowering the price they paid for the car will find themselves disappointed. The Massachusetts DMV has the option to use the car's "fair market value" (not the car price) as the basis for calculating sales tax.

The Massachusetts Department of Motor Vehicles establishes what the car is worth on the open market by referring to the Kelley Blue Book or other reliable sources of information about used car prices. If the DMV concludes that the car's fair market value is greater than the purchase price, the sales tax can be assessed based on the fair market value.

If you’re buying the car from a private party, you must declare the car's fair market value to the DMV and pay the appropriate amount of sales tax based on that value. Failing to do so may result in fines and penalties.

How to Avoid Paying Sales Tax on a Car in Massachusetts?

Sorry to burst your bubble, but property tax, income tax, sales tax, and other taxes are part of life. There is no way to legally avoid paying sales tax on used cars in Massachusetts or in any other state—unless you meet an exemption.

Massachusetts Car Sales Tax Exemptions

Here are some tax exemptions for used vehicle purchases, as listed on the Massachusetts DMV website:

Motor vehicle is transferred to an insurer (MVU-34 form).
Motor vehicle is a gift. If the donor paid any sales or use tax before in the state of Massachusetts, the transfer of ownership of a motor vehicle, trailer, or other vehicle to a recipient is tax-exempt. The donor will need to fill out the MVU-24 form.
Selling or transferring a motor vehicle, trailer, or other vehicle to or from a business entity can be exempted from taxation (MVU-25).
Sale or transfer between family members (parents, spouses, children, or siblings) is free of taxation as long as the transferor paid any Massachusetts sales or use tax before (MVU-26).
Transfer by repossession (Form MVU-30).
Transfer to a disabled person (MVU-33). Selling or transferring a motor vehicle to and for the use of people with partial or complete disabilities.
If you qualify for these exemptions, you should present evidence to the DMV.

Moving to a State With No Vehicle Sales Tax

If you plan to move to a state with no sales tax, you could defer purchasing a car until after your relocation. Otherwise, we don't recommend attempting to avoid paying car sales tax in Massachusetts or anywhere else. The thousands of dollars you might save are not worth the legal and financial implications, nor the loss of your peace of mind.

How to Pay Massachusetts Vehicle Sales Tax

Here's how to pay car sales tax in Massachusetts after you’ve purchased a used car from a private seller:

1. Calculate sales tax. The Massachusetts sales tax rate on cars is 6.25 percent. To figure out how much the sales tax is, multiply the price of the car by 0.0625. If you bought a car for $10,000, for instance, the sales tax would be $625. If you like, use our sales tax calculator.
2. Do the paperwork. You'll need to fill out a Motor Vehicle Certificate of Payment of Sales or Use Tax Form (ST-7R) and an Application for Registration and Title (RMV-1). When you fill out these forms, you will need to give information about the car, the purchase price (or fair market value), and yourself.
3. Turn in the paperwork and payment. Bring the completed paperwork and the sales tax payment to the Registry of Motor Vehicles (RMV) office in your area. You can pay the sales tax with a check or money order made out to "Massachusetts Department of Revenue," a credit card, or an electronic funds transfer (EFT).
4. Get your new registration and title. Once you've paid the sales tax and turned in the necessary paperwork, you'll get your new registration and title for the car. The title and registration will show that you bought the car and that the sales tax has been paid. You will also get new license plates.
If you live in Massachusetts and bought a car in another state and paid sales tax there, you might be able to get a credit for the Massachusetts sales tax.
