Illinois tollway payments go to the Illinois Tollway Authority, not to individual toll plazas

When you drive on an Illinois tollway — the I-90, I-88, I-355, or I-294 — you incur a toll debt that the Illinois Tollway Authority tracks and bills you for. You do not pay at the booth anymore; instead, you receive a bill in the mail weeks later, or you can set up an account to pay before a bill arrives. The Illinois Tollway Authority is a state agency that operates these highways, and it is the only place you pay.

If you drove without a transponder (the electronic tag mounted on your windshield), the tollway photographed your license plate and mailed you an invoice. If you have an I-PASS transponder, the toll was deducted from your prepaid account balance automatically. Either way, the debt flows to the same place: the Illinois Tollway Authority's payment system.

Key Takeaways

  • The Illinois Tollway Authority sends bills by mail for tolls charged to your license plate, usually within two to four weeks of driving.
  • You can pay a bill online at illinoistollway.com, by phone at 1-800-UC-IPASS, by mail, or in person at a payment location.
  • An I-PASS transponder account lets you prepay and avoid bills, and you can check your balance and add money online or by phone anytime.
  • If you do not pay within 30 days, late fees and collection notices begin, and unpaid tolls can affect your vehicle registration renewal.
  • You can dispute a toll charge if you believe it was incorrect, but you must contact the Illinois Tollway Authority within a set timeframe to do so.

How to pay a bill you received in the mail

When the Illinois Tollway Authority sends you an invoice, it includes the toll amount, the date you drove, your license plate number, and a due date. The bill will show one or more tolls from a single trip or multiple trips. You have several ways to pay this bill.

The fastest method is online at illinoistollway.com. Go to the "Pay a Toll Bill" section, enter your invoice number and license plate, and pay by debit card or credit card. You can also call 1-800-UC-IPASS (1-800-824-4727) and pay over the phone with a card. If you prefer to mail a check, write your invoice number on the check, include the payment stub from your bill, and send it to the address printed on the invoice. Some payment locations also accept cash or card payments in person, though these are less common and you should verify the location before going.

Payment by any method usually posts within one to three business days. If you pay online or by phone, you will receive a confirmation number when ready. Keep this number in case you need to dispute the charge later or verify payment.

Setting up an I-PASS account to avoid future bills

An I-PASS transponder is a small electronic device that mounts on your windshield and communicates with toll readers as you drive. Instead of receiving a bill, tolls are deducted automatically from a prepaid account balance. You control how much money sits in the account and can add funds online, by phone, or at a payment location.

To open an I-PASS account, visit illinoistollway.com or call 1-800-UC-IPASS. You will need your driver's license, vehicle information, and a payment method (debit card or credit card). The transponder itself costs a one-time fee, which varies but is typically under $20. Once activated, your account is ready to use when ready on all Illinois tollways.

The main advantage is convenience: you never receive a bill, tolls are charged at a lower rate than plate-based tolls, and you can check your balance and add money anytime online. If your balance runs low, you can set up automatic replenishment so funds are added when the balance drops below a threshold you choose. This prevents you from accidentally driving with an empty account.

What happens if you do not pay on time

If your bill is not paid by the due date, the Illinois Tollway Authority adds a late fee to your account. The amount of the late fee depends on how far past the due date you are, but it typically ranges from $10 to $25 per unpaid toll. After 30 days, the authority may send a collection notice or refer the debt to a collections agency.

Unpaid Illinois tollway debt can also affect your ability to renew your vehicle registration. The Illinois Secretary of State's office shares information with the Illinois Tollway Authority, and if you have an outstanding toll debt, your registration renewal may be blocked until you pay. This means you cannot legally drive the vehicle, even if your current registration has not expired yet.

If you are struggling to pay, contact the Illinois Tollway Authority directly at 1-800-UC-IPASS. Some payment plans or hardship options may be available, though these are not may provide. The sooner you reach out, the more options you may have before collection proceedings begin.

Disputing a toll charge

If you believe a toll charge is incorrect — for example, you were charged twice for the same trip, or you did not drive on that date — you can dispute it. Contact the Illinois Tollway Authority at 1-800-UC-IPASS or visit illinoistollway.com to file a dispute. You will need your invoice number, the date of the toll, and an explanation of why you believe the charge is wrong.

The Illinois Tollway Authority investigates disputes by reviewing toll records and video footage from the toll plaza or reader. This process typically takes two to four weeks. If the authority agrees with you, the charge will be removed and any payment you made will be refunded or credited to your account. If the authority disagrees, you will receive a written explanation of why the charge stands.

Disputes must be filed within a certain timeframe — usually within 30 to 90 days of the charge, depending on the circumstances. Check your bill or contact the authority to confirm the important date for your specific situation. Filing a dispute does not stop late fees from accruing, so if you believe a charge is wrong but want to avoid late fees while the dispute is pending, you may want to pay the bill and request a refund after the dispute is resolved.

Paying tolls if you do not have a permanent Illinois address

If you drove on an Illinois tollway but do not live in Illinois, the Illinois Tollway Authority will still send you a bill based on your out-of-state license plate. The bill will be mailed to the address on file with your home state's motor vehicle department. This can take longer to arrive than bills sent within Illinois, so you may not receive it for four to six weeks.

You can still pay online at illinoistollway.com or by phone at 1-800-UC-IPASS using your invoice number and license plate. If you plan to drive Illinois tollways regularly, opening an I-PASS account is especially useful because you avoid the mail delay and can manage your account from anywhere.

Frequently Asked Questions

How long does it take to receive a toll bill in the mail?

Most bills arrive within two to four weeks of the toll being charged. If you drove on a weekend or holiday, the bill may take slightly longer. If more than six weeks have passed and you have not received a bill, contact the Illinois Tollway Authority at 1-800-UC-IPASS to confirm your address is correct.

Can I pay a toll bill with a debit card or only a credit card?

Both debit and credit cards are accepted online and by phone. If you pay by mail with a check, no card is needed. Some in-person payment locations may have different payment method options, so call ahead to confirm.

What if I lost my I-PASS transponder?

Contact the Illinois Tollway Authority at 1-800-UC-IPASS to report it lost. They can deactivate the old transponder and issue a replacement. Any balance remaining in your account will transfer to the new transponder. There may be a replacement fee.

Will unpaid tolls show up on my credit report?

Unpaid tolls typically do not appear on your credit report unless the debt is referred to a collections agency and the agency reports it. However, unpaid tolls can block your vehicle registration renewal, which is a separate consequence. Paying as soon as possible prevents both outcomes.

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

Yes. If you overpaid, the Illinois Tollway Authority will either refund the overage to your original payment method or credit it to a future bill or I-PASS account. Contact them at 1-800-UC-IPASS with your invoice number to request a refund.
