Pay Illinois tolls through I-PASS or Tollway.illinois.gov

Illinois toll roads are managed by the Illinois Tollway, and you can pay online in two ways: set up an I-PASS account for automatic payments, or pay a single toll trip through Tollway.illinois.gov without creating an account. I-PASS is the faster option if you use toll roads regularly—the transponder mounts on your windshield and charges your account automatically. If you drove a toll road without a transponder or borrowed a car, you can look up and pay that specific toll online within a set window.

The Illinois Tollway operates the Chicago-area toll roads, including the Tri-State Tollway (I-94/I-90), the Reagan Tollway (I-88), the Veterans Memorial Tollway (I-355), and the Illinois Tollway (I-90 north of Chicago). Tolls vary by location and vehicle type, and rates change periodically—the Tollway posts current rates on its website.

Key Takeaways

  • I-PASS is a prepaid account with a windshield transponder that charges tolls automatically and costs less per toll than paying without one.
  • You can pay a single toll online at Tollway.illinois.gov without an I-PASS account, but you must pay within a specific window (usually 7 to 14 days after driving the toll road).
  • If you do not pay a toll on time, the Tollway sends a violation notice to the vehicle's registered owner, and unpaid tolls accrue late fees and penalties.
  • I-PASS accounts can be set up online, by phone, or at a customer service center, and you can add funds, view your balance, and manage your account online anytime.

Setting up an I-PASS account online

Go to I-PASS.com and select "Open an Account" to create a new I-PASS. You will need a valid driver's license or state ID, a current email address, and a payment method (credit card, debit card, or bank account). The account setup takes about 10 minutes and asks for your vehicle information, including license plate number and vehicle type.

After you create the account, you choose how much money to add to your prepaid balance—the minimum varies but typically starts at $25 to $50. The Tollway then mails you a transponder, which usually arrives within 7 to 10 business days. Once it arrives, mount it on your windshield inside your vehicle, set up it through your I-PASS account online, and tolls will begin charging automatically when you use a toll road.

I-PASS customers pay a lower per-toll rate than drivers without a transponder. Rates are posted on I-PASS.com and change periodically. You can check your balance, view your toll history, and add funds to your account anytime through the I-PASS website or mobile app.

Paying a single toll without an I-PASS account

If you drove a toll road without a transponder—for example, in a rental car or a borrowed vehicle—you can pay that toll online at Tollway.illinois.gov under "Pay a Toll." You will need your license plate number and the date you used the toll road. Enter those details, and the system will show you the toll amount owed.

Payment must be made within a specific window, usually 7 to 14 days after you drove the toll road. The exact important date appears on the payment screen. You can pay by credit card, debit card, or bank account. Once payment is processed, you are done—no account is created, and you do not receive a transponder.

If you miss the payment important date, the Tollway sends a violation notice to the vehicle's registered owner. The notice includes the original toll amount plus a violation fee. If the violation notice is not paid within the timeframe stated on the notice, additional penalties and late fees explore, and the debt can be referred to a collection agency.

Managing your I-PASS account and adding funds

Log into your I-PASS account at I-PASS.com to view your current balance, recent toll charges, and transaction history. You can add funds to your account at any time through the website or mobile app using a credit card, debit card, or bank account. Many customers set up automatic replenishment, which adds a set amount to their account when the balance drops below a certain level—this prevents your account from running empty while you are driving.

If you need to update your vehicle information, change your payment method, or suspend your account temporarily, you can do all of that online. If you have questions or need help, the I-PASS customer service line is available by phone, and you can also visit an I-PASS customer service center in the Chicago area.

What happens if you do not pay a toll

If you drive a toll road without a transponder and do not pay within the important date, the Tollway mails a violation notice to the address on file for your vehicle's license plate. The notice states the original toll amount, the violation fee, and the important date to pay. Violation fees are separate from the toll itself and add significantly to what you owe.

If you do not respond to the violation notice by the important date, the Tollway can refer the debt to a collection agency, and it may appear on your credit report. In some cases, the Tollway can place a hold on vehicle registration renewal until the debt is paid. Paying promptly when you receive the notice is the fastest way to resolve the matter.

Paying tolls if you have an out-of-state vehicle

If you live outside Illinois but drive Illinois toll roads regularly, you can open an I-PASS account using an out-of-state driver's license or ID. The process is the same as for Illinois residents: go to I-PASS.com, create an account, add funds, and wait for your transponder to arrive by mail. Rates for I-PASS holders are the same regardless of where you live.

If you are visiting Illinois and drive a toll road in a rental car or your own vehicle, you can pay the toll online at Tollway.illinois.gov within the payment window. Some rental car companies offer I-PASS transponders for a daily fee, which may be cheaper than paying the violation fee if you forget to pay online.

Frequently Asked Questions

Can I pay Illinois tolls by mail?

No, the Tollway does not accept mail payments for tolls. You must pay online at Tollway.illinois.gov or through an I-PASS account. If you receive a violation notice for an unpaid toll, the notice will include instructions for payment, which are also online only.

What if I drove a toll road but do not know which one or when?

If you received a violation notice, it will state the toll road and the date. If you have not received a notice yet and want to pay proactively, contact I-PASS customer service by phone—they can look up tolls by license plate and date range. You can also check your credit card or bank statement to see when the charge was made.

Do I need an I-PASS to drive Illinois toll roads?

No, you can drive toll roads without an I-PASS, but you must pay the toll online within the important date. I-PASS holders pay a lower per-toll rate, so if you use toll roads frequently, an I-PASS saves money over time.

Can I transfer my I-PASS to a different vehicle?

Yes, you can update your vehicle information in your I-PASS account online anytime. If you sell your car or get a new one, log in and change the license plate number. Your transponder stays the same and will work on the new vehicle once you update your account.

What if my I-PASS transponder is lost or damaged?

Contact I-PASS customer service through I-PASS.com or by phone to report the issue. They can deactivate the old transponder and mail you a replacement, usually within 7 to 10 business days. There may be a replacement fee depending on your account status.
