You can pay Illinois tolls online through the Illinois Tollway's official website or through their mobile app, without needing to set up an account in advance

The Illinois Tollway operates toll roads in the Chicago area and across northern Illinois. If you drive these roads regularly or occasionally, you have options for paying tolls without stopping at a booth. The fastest online method is to pay a toll bill after you've driven — the Tollway sends you an invoice by mail or email, and you can pay it on their website. If you want to avoid bills altogether, you can set up a prepaid account called an I-PASS, which charges your account automatically as you use the tolls.

This guide explains how to pay tolls online, what to expect at each step, and which method works best depending on how often you use Illinois toll roads.

Key Takeaways

  • You can pay a toll bill online at illinoistollway.com without creating an account, using your invoice number and the license plate that was photographed.
  • An I-PASS is a prepaid account that deducts tolls automatically as you drive; you load money into it online and it works on all Illinois Tollway roads.
  • The Illinois Tollway mobile app lets you check your I-PASS balance, add money, and view your toll history from your phone.
  • If you do not pay a toll bill within a set time, the Tollway can add late fees and report the debt to a collection agency.
  • Rental car companies sometimes charge their own fees on top of toll costs if you use their tolls; check your rental agreement before driving toll roads.

Paying a toll bill online after you drive

When you drive a toll road without an I-PASS or cash payment, the Tollway photographs your license plate. Within a few weeks, they mail or email you an invoice for that toll. You do not need to create an account to pay this bill online.

Go to illinoistollway.com and look for the "Pay a Toll Bill" or "Pay Now" option on the homepage. You will need your invoice number (printed on the bill or in the email) and the license plate number that was photographed. Enter both, and the website will show you the amount owed. You can pay by credit card, debit card, or electronic check. The payment processes when ready, and you receive a confirmation number by email.

This method works if you drive tolls only occasionally. The downside is that you receive a separate invoice for each toll transaction, and each one carries a small administrative fee added to the toll itself.

Setting up an I-PASS account for automatic toll payment

An I-PASS is a prepaid account linked to a small transponder (a device about the size of a matchbox) that you mount on your windshield. As you drive through a toll plaza, the transponder communicates with the reader, and the toll is deducted from your account balance automatically. You never stop, and you never receive an invoice for each trip.

To set up an I-PASS, visit illinoistollway.com and select "Open an I-PASS Account" or "Get I-PASS." You will enter your name, address, phone number, email, and the vehicle's license plate number. You choose how much money to load into the account (the minimum varies but is typically $25 to $40). You pay for the account and the transponder using a credit card, debit card, or electronic check. The Tollway mails the transponder to you, which usually arrives within 5 to 10 business days.

Once the transponder arrives, mount it on your windshield following the instructions included in the package. The next time you drive a toll road, the transponder will be read automatically. You can check your balance and add money online at any time through your I-PASS account.

Adding money to your I-PASS online

When your I-PASS balance drops below a certain threshold (usually $10), you can add money online before the account runs empty. Log into your I-PASS account at illinoistollway.com using your email and password. Select "Add Funds" or "Replenish Account," choose the amount you want to add, and pay by credit card, debit card, or electronic check.

You can also set up automatic replenishment, which adds a fixed amount to your account whenever the balance falls below a level you choose. This means you never have to think about it — the account stays active as long as your payment method is current. If you set up automatic replenishment, review your account every few months to make sure the charges are correct and the transponder is still working.

Using the Illinois Tollway mobile app

The Illinois Tollway offers a free mobile app for iPhone and Android that lets you manage your I-PASS from your phone. read the app from the Apple App Store or Google Play Store, then log in with the same email and password you use on the website.

Through the app, you can check your current balance, add money, view your recent toll transactions, and update your payment method. You can also receive notifications when your balance is low or when a payment fails. The app is useful if you drive tolls frequently and want to monitor your account without opening a web browser.

What happens if you do not pay a toll bill

If you receive a toll bill and do not pay it within the time shown on the invoice (usually 30 days), the Tollway adds a late fee. The amount of the late fee varies but is typically $10 to $25 per unpaid toll. If you continue not to pay after a second notice, the Tollway can report the debt to a collection agency, which may contact you by phone or mail and can affect your credit report.

If you believe you received a bill in error — for example, if your license plate was misread or if you paid the toll and the Tollway did not record it — you can dispute the bill through the website. Look for a "Dispute a Toll" or "Challenge a Toll" option on illinoistollway.com. You will need to provide details about when and where you drove and explain why you believe the charge is wrong. The Tollway reviews disputes and responds by mail within a few weeks.

Tolls on rental cars and transponder issues

If you rent a car and drive Illinois toll roads, check your rental agreement before you leave the lot. Some rental companies charge a daily fee (often $3 to $5 per day) if you use toll roads, even if you pay the toll itself. Other rental companies have their own transponders and bill you directly for tolls plus a service fee. A few companies let you use tolls at no extra charge. Reading the agreement upfront saves you from unexpected charges on your credit card after you return the car.

If your I-PASS transponder stops working or is damaged, contact the Illinois Tollway customer service line or visit a customer service center to request a replacement. There is usually a small fee for a replacement transponder. If you move out of Illinois or no longer need your I-PASS, you can close your account online and request a refund of any remaining balance.

Frequently Asked Questions

Can I pay Illinois tolls with cash?

Some toll plazas still have cash lanes, but they are becoming less common. The Tollway encourages electronic payment through I-PASS or online bill payment. If you prefer cash, check the Tollway website or call customer service to confirm which plazas accept it before you drive.

What if I lose my I-PASS transponder?

Contact the Illinois Tollway customer service center or visit their website to report it lost. You can request a replacement transponder, which the Tollway will mail to you. There is usually a replacement fee. Until the new transponder arrives, your account remains active but tolls will be charged by license plate and you will receive bills by mail.

Do I need an I-PASS if I only drive tolls once or twice a year?

No. If you drive tolls infrequently, paying each bill online when it arrives is simpler and cheaper than buying an I-PASS transponder. An I-PASS makes sense if you drive tolls at least a few times per month, because the transponder fee and account setup cost more than you save on occasional trips.

Can I use my I-PASS in other states?

I-PASS works on toll roads in Illinois, Indiana, and Ohio through an interoperability program. However, it does not work in other states like Wisconsin, Iowa, or on toll roads in the Northeast. If you travel to other toll states, you may need to pay tolls separately or use that state's system.

What should I do if the Tollway charged me twice for the same toll?

Log into your I-PASS account or visit illinoistollway.com and look for a dispute or challenge option. Provide details about the date, time, and location of the toll, and explain that you were charged twice. The Tollway reviews duplicate charge claims and typically refunds the extra charge within a few weeks.
