What Pay by Plate MA is and how it charges you

Pay by Plate MA is Massachusetts's system for collecting tolls on certain highways without requiring a physical toll booth or transponder. When you drive through a tolled section, a camera reads your license plate, and the state mails you an invoice or charges an account you've set up in advance.

The system operates on Interstate 93 (the tunnel section in Boston), the Tobin Bridge, and the Ted Williams Tunnel. If you drive through one of these tolled locations, you will receive a bill — either by mail or through an online account — within a few days to a few weeks. There is no way to avoid the toll by using a different route on these specific highways.

Massachusetts also offers a transponder option called E-ZPass, which deducts tolls automatically from a prepaid account as you drive through. Pay by Plate MA is the default system for drivers who do not have an E-ZPass transponder.

Key Takeaways

  • Pay by Plate MA reads your license plate at tolled locations and sends you a bill by mail or email within days to weeks.
  • You can set up an online account to pay bills when ready and avoid late fees, or wait for a mailed invoice.
  • If you drive through a tolled location without paying within 30 days, late fees and penalties begin to accumulate.
  • E-ZPass transponders offer a lower per-toll rate than Pay by Plate MA and deduct tolls automatically from your account.
  • Out-of-state drivers receive bills by mail; Massachusetts residents can set up online accounts to manage payments faster.

How to set up a Pay by Plate MA account

You do not have to create an account to use Pay by Plate MA — the state will bill you by mail if you do nothing. However, setting up an account online lets you see charges when ready, pay before a mailed bill arrives, and avoid late fees.

To create an account, visit the Massachusetts Department of Transportation (MassDOT) Pay by Plate website. You will need your license plate number, vehicle registration state, and an email address. The account is free to open. Once you log in, you can view any tolls charged to your plate and pay them directly using a credit card or bank account.

If you are an out-of-state driver, you can still create an account, but the state will also mail you an invoice. Setting up an account straightforward gives you the option to pay online before the paper bill arrives.

When and how you receive a bill

If you do not have an online account, MassDOT will mail you an invoice to the address on your vehicle registration. This typically arrives 5 to 15 business days after you drive through a tolled location. The invoice shows the date you drove through, the toll amount, and payment instructions.

You can pay a mailed bill by check, money order, or credit card. Payment instructions are printed on the invoice. If you have an online account, you will see the charge appear there first — often within 24 to 48 hours — and you can pay when ready without waiting for the mail.

If you do not pay within 30 days of the toll date, late fees begin. The first late fee is typically $25, and additional penalties can accumulate if payment continues to be delayed. After 60 days unpaid, the state may suspend your vehicle registration or refer the debt to a collection agency.

The difference between Pay by Plate MA and E-ZPass

Pay by Plate MA charges a higher per-toll rate than E-ZPass. For example, a single toll through the I-93 tunnel costs more when paid by plate than when paid with an E-ZPass transponder. The exact difference varies by location and toll type, but E-ZPass is consistently cheaper.

E-ZPass requires you to purchase a transponder (a small device that mounts on your windshield) and set up a prepaid account. The transponder deducts tolls automatically as you drive through, and you receive a monthly statement. E-ZPass also works in other states that participate in the E-ZPass network, making it useful if you travel outside Massachusetts.

If you use a tolled highway regularly, E-ZPass saves money over time. If you only drive through occasionally, Pay by Plate MA may be simpler because it requires no equipment or advance setup — you straightforward drive through and pay the bill when it arrives.

What to do if you receive a bill you don't recognize

If you receive a Pay by Plate MA bill for a toll you did not drive through, or if the date or amount seems wrong, contact MassDOT's Pay by Plate customer service. You can dispute the charge by phone or through your online account. Have your invoice or account details ready when you call.

Disputes are common when a vehicle is misidentified, when a plate is misread, or when a vehicle has been sold or transferred. If you sold your vehicle, the new owner is responsible for tolls incurred after the sale date. If you believe the toll was charged in error, provide MassDOT with the date, time, and location of the disputed toll, and they will investigate.

Do not ignore a bill you believe is wrong. Disputing it within 30 days prevents late fees from accumulating while the investigation is underway.

Late fees and what happens if you don't pay

Tolls are due within 30 days of the toll date. If you do not pay by that important date, a $25 late fee is added to your bill. If payment is still not made after 60 days, additional penalties and collection actions may begin.

Unpaid tolls can result in vehicle registration suspension, meaning you will not be able to renew your registration or pass a safety inspection. The state may also report the debt to a collection agency, which can affect your credit. In some cases, the Registry of Motor Vehicles will place a hold on your license plate until the debt is paid.

If you are unable to pay a bill, contact MassDOT customer service to discuss payment options. Some programs or hardship provisions may be available depending on your situation.

Frequently Asked Questions

Do I have to pay a toll if I drive through by mistake?

Yes. There is no way to reverse or waive a toll charge once you have driven through a tolled location. Your only option is to dispute the charge if you believe it was applied in error — for example, if your plate was misread or if you were not actually in the vehicle.

Can I use a transponder from another state on Massachusetts tolls?

E-ZPass transponders from other states work on Massachusetts tolls because E-ZPass is a multi-state network. If you have an E-ZPass account from another state, you can use it on I-93, the Tobin Bridge, and the Ted Williams Tunnel without setting up a separate Massachusetts account.

What if I move and my registration address changes?

Update your vehicle registration with the Registry of Motor Vehicles. MassDOT uses the registration address on file to mail bills, so if you move without updating your registration, bills may go to your old address and you could miss payment important date. If you have an online account, update your email address there as well.

How long does it take to get an E-ZPass transponder?

E-ZPass transponders can be ordered online through MassDOT and typically arrive within 5 to 10 business days. You must set up a prepaid account before the transponder is activated. Once activated, tolls are deducted automatically from your account balance.

Can I get a refund if I overpaid my toll bill?

If your account has a credit balance — for example, if you prepaid more than the tolls owed — you can request a refund through your online account or by contacting MassDOT customer service. Refunds are typically processed within 4 to 6 weeks.
