Pay tolls online through the Maryland Department of Transportation toll system

You can pay Maryland tolls online by visiting the official MDTA (Maryland Department of Transportation Authority) website or using their mobile app. The system accepts payment for tolls you've already incurred on Maryland toll roads, bridges, and tunnels. Payment typically processes within one to two business days, and you can use a credit card, debit card, or bank account to settle your toll bill.

The online payment option exists for drivers who either don't have a toll transponder (like E-ZPass) or prefer to pay individual tolls after driving rather than maintaining a prepaid account. This is different from setting up an E-ZPass account, which is a separate system that charges tolls automatically as you drive.

Key Takeaways

  • Visit mdta.maryland.gov or use the MDTA mobile app to pay tolls with a credit card, debit card, or bank account.
  • You'll need your vehicle's license plate number and the date you drove the toll road to locate your toll charges.
  • Payment processes within one to two business days, so plan ahead if you're trying to avoid late fees.
  • If you drive Maryland tolls regularly, an E-ZPass transponder costs less per toll than paying individually each time.

Steps to pay a toll online through MDTA

Start by going to mdta.maryland.gov and look for the "Pay Tolls" or "Pay a Toll Invoice" section on the homepage. Click that link to enter the toll payment portal.

Enter your vehicle's license plate number and the state where it's registered. Then provide the date you drove the toll road — this helps the system locate your toll charge. If you're not sure of the exact date, enter your best estimate; the system will show you all tolls charged to that plate within a date range.

Review the toll charges displayed. The system will show you which road or bridge you were charged for, the amount, and the date. If multiple tolls appear and you only want to pay one, select the specific toll before proceeding to payment.

Enter your payment method: credit card, debit card, or bank account information. Provide your billing address and email address. The system will send you a receipt to that email after payment processes. Click to confirm and submit your payment.

Using the MDTA mobile app instead of the website

The MDTA mobile app (available on iOS and Android) offers the same toll payment function as the website. read the app from your phone's app store and open it. Select "Pay a Toll" from the main menu.

Enter your license plate number, state of registration, and the date you drove. The app will display your toll charges the same way the website does. Select the toll you want to pay, enter your payment information, and submit. You'll receive a confirmation number and email receipt.

The app can be faster if you're paying on your phone while driving (as a passenger) or if you want to save your payment method for future tolls. However, the website works equally well if you prefer to pay from a computer.

What happens after you submit payment online

Your payment enters the MDTA processing system when ready, but it typically takes one to two business days to post to your account. During this time, the toll is still technically outstanding in the system, though you have a receipt showing you've paid.

Once the payment clears, you'll receive a confirmation email from MDTA. If you were close to a late fee or violation notice, the online payment record protects you — MDTA can see that you initiated payment before the important date, even if processing takes a day or two.

If you don't receive a confirmation email within three business days, log back into your account and check your payment history. You can also call MDTA customer service at 1-888-321-6824 to verify the payment went through.

When to use online toll payment versus E-ZPass

Pay tolls online when you drive Maryland toll roads only occasionally — a few times a year or less. The per-toll cost is the same whether you pay online or with E-ZPass, but E-ZPass requires buying a transponder (usually $25 to $35) and maintaining a prepaid account balance.

Switch to E-ZPass if you drive Maryland tolls more than once or twice a month. The transponder pays for itself quickly because E-ZPass holders receive discounts on most Maryland tolls — typically 10 to 25 percent off the standard rate depending on the road. E-ZPass also means you don't have to remember to pay after each trip; the charge happens automatically.

You can set up an E-ZPass account through the same MDTA website. If you already have E-ZPass from another state (like Virginia or Pennsylvania), it works on Maryland roads without any additional setup.

Common reasons a toll charge might not appear online

If you drove a Maryland toll road but don't see a charge when you search by license plate, the toll may not have been captured yet. The system can take 24 to 48 hours to record a toll after you drive it, especially during peak traffic times. Try searching again the next day.

If you used a rental car, the toll was likely charged to the rental company's account, not your personal license plate. Contact the rental agency to ask how they handle tolls — some charge you directly, others add it to your final bill, and some have their own toll payment arrangements.

If you drove with an E-ZPass transponder mounted on your windshield, the toll should have been deducted from your E-ZPass account automatically, not charged to your license plate. Check your E-ZPass account balance instead of searching for a plate-based toll.

Frequently Asked Questions

Can I pay a toll online if I don't remember the exact date I drove?

Yes. Enter your best estimate of the date, and the system will show all tolls charged to your license plate within a range of several days around that date. You can then select the correct toll from the list. If you're still unsure, call MDTA customer service at 1-888-321-6824 and provide your license plate number; they can tell you which tolls are outstanding.

What if I drove someone else's car and got charged a toll?

The toll was charged to that car's license plate, not to you. The vehicle owner needs to pay the toll through their own MDTA account or contact MDTA to dispute the charge if they believe it was incorrect. If you borrowed the car, ask the owner to pay and they can ask you to reimburse them.

Do I get a receipt when I pay a toll online?

Yes. MDTA sends a confirmation email to the address you provide during payment. The email includes your receipt number, the toll amount, the date paid, and your payment method. Keep this email in case you need to reference the payment later or dispute a charge.

Is there a fee for paying tolls online?

No. MDTA does not charge a processing fee for online toll payments. The amount you see is the toll itself; nothing extra is added. Credit card and debit card companies may charge their own processing fees depending on your bank, but MDTA does not.

What if my payment is declined?

The system will tell you when ready if your card or bank account is declined. Check that your payment information is correct, your card hasn't expired, and your account has sufficient funds. Try again with the same method or use a different payment method. If the problem persists, contact your bank or card issuer to confirm the transaction is allowed.
