How Much are Used Car Sales Taxes in Maine?

While buying a used car in Maine is a great way to save some money, there's one thing you can't overlook—sales tax.
Maine's vehicle sales tax is 5.5% of the vehicle's purchase price. Unlike many other states, Maine has no local sales tax on vehicle purchases. This makes Maine one of the easier states in which to manage sales tax collection, filing, and remittance.

Do you Pay Taxes When you Purchase a Vehicle From a Private Party in Maine?

When buying a car in Maine, you’ll pay 5.5% of the vehicle’s purchase price, whether you buy from a private seller or a car dealer. Maine tax law does not discriminate between the two. Unless you qualify for a tax exemption (covered below), you’ll owe tax on your vehicle purchase.

Sales Tax vs Use Tax

Sales tax is a percentage of a car's purchase price, as we’ve already discussed. You owe it to the state of Maine when you buy a vehicle and register it in Maine.

Use taxes are pretty much the same thing, but for out-of-state vehicles. When you buy a vehicle out-of-state and register it in Maine, the state will levy a 5.5% use tax (the use tax rate is the same as the sales tax rate). The use tax essentially levels the playing field by ensuring that cars purchased in the state and cars brought into the state are taxed the same.

If you paid sales tax on your vehicle purchase in another state, Maine will usually deduct the other state’s tax so that you aren’t double-taxed. There are four potential scenarios.

1. You paid exactly 5.5% sales tax in Nebraska (the only other state with the same tax rate as Maine), in which case Maine will give you a pass.
2. You paid no sales tax in another state, in which case you owe the full 5.5% Maine sales tax. Let's say you bought a used car in Alaska and didn’t pay any sales tax, given Alaska's 0% tax rate. You’ll pay Maine’s full 5.5% sales tax.
3. You paid less than 5.5% sales tax in another state, in which case Maine charges you the difference. Let’s say you bought a used Jeep Wrangler in North Dakota for $20,000. North Dakota’s tax rate is 4%, so you paid $800 (.04 X $20,000) in North Dakota tax. When you go to register the car in Maine, your total tax bill will be $1,100 minus the $800 you already paid in North Dakota, for a total due of $300 to Maine.
4. You paid more than 5.5% in the other state (for example, Rhode Island levies a 7% tax on vehicle purchases). We wish we could tell you Maine will give you a refund, but no. At least they won’t charge you any more tax.
5. To report sales and use tax, fill out the use tax certificate (Form STMV-6U).

License Plates, Title And Registration Fees in Maine

In addition to the state sales tax, you may owe other fees when buying a car and registering it in Maine, such as vehicle registration fees and car title fees.

To register your vehicle at the Bureau of Motor Vehicles (BMV) branch office, you must show proof of car insurance. The first time you register a passenger vehicle, it will cost you $35, plus the $33 title transfer fee.

Maine's standard license plate fee is included in the registration fee. A vanity plate will cost an additional $25.

How is Used Car Sales Tax Calculated in Maine?

Sales tax in Maine is calculated based on the vehicle's purchase price. There are people who think they can outsmart the government by negotiating a low "official" purchase price and paying the rest in a side transaction. But Maine Revenue Services can’t be fooled so easily.

If Revenue Services suspects that the purchase price of the vehicle was artificially decreased, they will calculate sales tax based on the car’s fair market value.

Revenue Services establishes what the car is worth on the open market by referring to Kelley Blue Book or other reliable sources on used car prices. If they conclude that the car's fair market value is greater than its purchase price, they can opt to base sales tax on the fair market value.

It is important to note that underreporting the purchase price of a vehicle in order to avoid paying sales tax is illegal. If you are caught doing this, you could be subject to a fine of up to $5,000.

Here's how to pay Maine car sales tax after buying a used car from a private seller:

1. To transfer ownership of the vehicle, you and the seller must complete the necessary paperwork, including the bill of sale (when you buy a used car on PrivateAuto, we provide an official Maine bill of sale and prompt both of you to sign it in our app at the appropriate stage of the transaction process). You'll need the following documents to transfer car ownership in a private transaction:
2. The original car title with an odometer reading and the seller’s signature
3. Current proof of insurance.
4. The buyer and the seller’s valid driver’s licenses or IDs
5. Calculate the amount of sales tax due. Multiply the vehicle's purchase price by 5.5%.
6. Fill out the sales tax form.
7. Submit payment for all taxes and fees.
8. Get payment proof from the Maine Revenue Services.
9. Get your registration, title and new license plates. 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 your license plates in mail.

If you buy a used car from a private seller,it is recommended that both you and the seller go to a BMV branch office to finish the transaction, which protects both of you. If you do not complete the transfer of title within 30 days of the sale, you will be charged a late transfer penalty fee of $10.

How to Avoid Paying Sales Tax on Cars in Maine?

There’s really no way around it; taxes are part of life. You are required by law to pay sales tax on private used car purchases in Maine or any other state that charges sales tax—unless you meet an exemption.

Maine Car Sales Tax Exemptions

Here are some sales tax exemptions for used vehicle purchases in Maine:

Non-residents. If you are not a Maine resident and purchase a vehicle in Maine, you are not required to pay sales tax in Maine. But you may need to pay them in the other state, depending on whether it levies sales tax on used vehicle purchases.
Government agencies. Federal, state, and local governments are exempt from paying sales tax on used vehicles.
Certain commercial vehicles. Farm trucks and commercial trailers are two examples of commercial vehicles that may be exempt from sales tax.
Cars that are purchased for business use. If the vehicle is intended to be driven or transported outside of Maine immediately after delivery and will be used solely for the qualifying resident business's out-of-state activities.

Is Purchasing a Car from a Dealer Better?

Many people believe that buying from a car dealer is a magical way to avoid all of the hassle (and possibly a fee here and there). In fact, going to a Maine dealer will cost you more money, and it's not all that hassle free—unless spending 3 hours in a dealership is your idea of a good time.

Dealerships charge documentation fees above and beyond all the other taxes and fees you have to pay (which are exactly the same whether you buy from a dealer or a private seller). Average documentation fees in Maine are $410.
Dealers usually charge higher prices on used cars. Their business model is based on buying as low as possible and selling as high as possible to make the spread that keeps them in business. Cut out the middleman and go directly to private sellers to get the best deals.

We do admit that dealers bring a certain amount of convenience that you don’t traditionally get when you buy from a private seller. In fact, that’s why PrivateAuto exists. We give you dealer-like convenience in the palm of your hand while allowing you to transact peer-to-peer with regular folks like yourself—unlike our competitors.

When you shop for used cars from private sellers on PrivateAuto, you can avoid the doc fee and get lower prices.

Maine Vehicle Sales Tax FAQ


How are car trade-ins taxed in Maine?

You may decide to trade in your old car to reduce the overall cost of your new vehicle. When you trade in a car, the dealership will assess its worth and offer you a credit. This credit will be deducted from the total price of your vehicle.

The sales tax in Maine is only applied to the net price of your new car after the trade-in credit is deducted. In other words, your trade-in’s value is not subject to taxes! This could save you a lot of money, depending on the value of your trade-in vehicle.
