You can pay Illinois tolls through I-PASS, the state's electronic toll system, or by mail if you receive a toll bill

Illinois tolls are collected on the Illinois Tollway system, which includes the Chicago area's major highways. If you drive these roads without a toll tag, you will receive a bill in the mail. The fastest way to pay is through I-PASS, the state's electronic toll collection system that lets you prepay and drive through toll plazas without stopping. You can also pay individual toll bills online, by phone, or by mail once they arrive at your address.

The method you use depends on whether you already have an I-PASS account or are paying a bill that arrived in the mail. Both routes are straightforward, but the timing and what you need differs between them.

Key Takeaways

  • I-PASS is an electronic toll tag you mount on your windshield that automatically deducts tolls from a prepaid account as you drive.
  • You can open an I-PASS account online at ipass.illinois.gov, add a vehicle, and fund your account with a credit or debit card.
  • If you received a toll bill in the mail, you can pay it online at illinoistollway.com using your bill number and the amount due.
  • Toll bills arrive 30 to 60 days after you drive the road, so paying by mail or online takes time — setting up I-PASS beforehand avoids bills entirely.

Setting up I-PASS to pay tolls automatically

I-PASS is the most convenient option if you drive Illinois tolls regularly. You purchase a toll tag (a small electronic device), mount it on your windshield, and link it to a prepaid account. When you drive through a toll plaza, the tag communicates with the reader and deducts the toll amount from your account balance. You can set up automatic replenishment so your account refunds itself when the balance drops below a certain amount.

To open an I-PASS account, go to ipass.illinois.gov and select "Open an Account." You will need a valid driver's license or state ID, a vehicle registration number, and a credit or debit card to fund the account. The toll tag itself costs $25 to $40 depending on the type, and you can order it during account setup. The tag arrives by mail within 7 to 10 business days. Once it arrives, mount it on the inside of your windshield in the upper driver's side corner, set up it through your online account, and add funds. Most people add $25 to $100 initially, though the amount depends on how often you drive tolled roads.

I-PASS accounts also give you a discount on tolls — typically 10 to 15 percent lower than the cash rate — so the tag pays for itself quickly if you drive tolls more than a few times per month.

Paying a toll bill that arrived in the mail

If you drove a tolled road without an I-PASS tag, the Illinois Tollway will mail you a bill 30 to 60 days later. The bill includes the toll amount, a processing fee (usually $2 to $5), and a due date. You can pay this bill online, by phone, or by mail.

To pay online, go to illinoistollway.com and select "Pay a Toll Bill." You will need the bill number (printed on the bill itself) and the amount due. Enter your payment method — credit card, debit card, or bank account — and submit. Payment is processed when ready, and you will receive a confirmation number. Keep this number for your records.

If you prefer to pay by phone, call the Illinois Tollway customer service line at 1-800-UC-TOLLS (1-800-828-6557). A representative will look up your bill using your license plate number or bill number and process your payment over the phone. If you pay by mail, write a check or money order, include the bill number, and mail it to the address printed on the bill. Mail payments take 7 to 10 business days to process.

What to do if you receive multiple toll bills

If you drove tolled roads several times without I-PASS, you may receive multiple bills over several months. Each bill is separate and has its own due date and processing fee. You can pay them individually online or all at once by phone.

Rather than paying each bill as it arrives, consider opening an I-PASS account to avoid future bills and fees. Once your account is active and your tag is mounted, any tolls you drive will be deducted from your prepaid balance instead of generating a bill. If you have already received bills, pay those through the online portal or by phone, then set up I-PASS for future drives.

Understanding toll amounts and discounts

Illinois toll rates vary by location and vehicle type. A standard passenger car toll ranges from $0.70 to $2.50 per plaza depending on which road you drive and which direction. Trucks and vehicles with trailers pay higher rates. I-PASS users pay a discount rate, typically 10 to 15 percent less than the posted cash rate.

When you receive a bill in the mail, the amount shown includes the full cash rate plus the processing fee. If you had used I-PASS, the toll would have been lower. This is one reason setting up I-PASS before you drive is worth the effort — the savings accumulate quickly, especially if you drive tolls regularly.

Updating your I-PASS account and managing your balance

Once your I-PASS account is open, you can log in anytime at ipass.illinois.gov to check your balance, view your toll history, add funds, or update your payment method. If your balance drops below $5, you will receive an email reminder (if you set up notifications). You can add funds manually or set up automatic replenishment, which charges your card when the balance falls below a threshold you choose.

If you move, change vehicles, or need to update your contact information, log into your account and edit your profile. If you sell your vehicle or no longer need the tag, you can request a refund of any remaining balance and deactivate the tag through your account. The refund process takes 7 to 10 business days.

Frequently Asked Questions

Can I pay a toll bill with a prepaid card or gift card?

Most toll bill payment portals accept Visa, Mastercard, American Express, and Discover. Prepaid cards and gift cards work if they are branded with one of these logos and have sufficient funds. Some payment systems also accept bank account transfers, which may be an option if your card is declined.

What happens if I don't pay a toll bill?

If a bill goes unpaid past the due date, the Illinois Tollway may send a second notice with a late fee added. If it remains unpaid, the debt can be referred to a collection agency, and the amount owed may appear on your credit report. Unpaid tolls can also prevent vehicle registration renewal in some cases.

Can I use I-PASS on other states' toll roads?

I-PASS works on most toll roads in the Midwest, including Indiana, Ohio, and parts of other states through reciprocal agreements. However, it does not work on all toll roads nationwide. Check the specific toll road's website to confirm I-PASS is accepted before you drive.

How long does it take to receive an I-PASS tag after I order it?

Standard delivery takes 7 to 10 business days. Expedited shipping is available for an additional fee if you need the tag sooner. You can drive tolls while waiting for your tag to arrive, but you will receive bills in the mail for those drives.

Is there a way to dispute a toll charge?

If you believe a toll charge is incorrect, contact the Illinois Tollway customer service at 1-800-UC-TOLLS with your bill number or toll transaction details. They can review the charge and issue a credit if an error is found. Disputes should be reported within 30 days of receiving the bill.
