You can pay Illinois tolls online through I-PASS, the state's electronic toll system, or through individual toll plaza websites

Illinois tolls are managed by the Illinois Tollway, a state agency that operates toll roads across northern Illinois. If you drive on the Tri-State Tollway (I-90/I-94), the Reagan Memorial Tollway (I-88), the Veterans Memorial Tollway (I-355), or the Illinois Tollway's other routes, you will either need an I-PASS transponder or you will receive a toll bill in the mail.

The fastest way to pay is through I-PASS, which lets you prepay tolls and drive through toll plazas without stopping. If you do not have I-PASS, you can pay individual toll bills online through the Illinois Tollway website, or you can set up an account to pay tolls as you incur them. Paying online stops late fees and collection notices from reaching you.

Key Takeaways

  • I-PASS is an electronic transponder you mount on your windshield that charges tolls automatically and offers a discount compared to paying by mail.
  • You can open an I-PASS account and add funds online at ipass.illinois.gov, and the transponder ships to your address within five to seven business days.
  • If you received a toll bill in the mail, you can pay it when ready on the Illinois Tollway website to avoid late fees and collection action.
  • Toll-by-plate (paying without a transponder) charges a higher rate, and unpaid toll-by-plate bills can result in vehicle registration holds and collection referrals.

Setting up I-PASS and prepaying tolls online

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 payment method (credit card, debit card, or bank account). The account setup takes about 10 minutes.

Once your account is open, you can add funds when ready. I-PASS charges a one-time transponder fee (currently $25 for a standard transponder, though this can vary), and you then add prepaid toll credit. The transponder ships within five to seven business days. You can add more funds to your account at any time through the website, and the system will notify you by email when your balance drops below a threshold you set.

I-PASS users pay a discounted toll rate compared to drivers who pay by mail or at toll plazas. The exact discount depends on the road and the toll amount, but I-PASS users typically pay 25 to 50 percent less per toll. Over time, this adds up significantly if you use toll roads regularly.

Paying toll bills that arrived in the mail

If you drove through a toll plaza without I-PASS and did not have a toll-by-plate account set up, the Illinois Tollway will mail you a bill. The bill includes the toll amount, a processing fee, and instructions for payment. You have 28 days from the bill date to pay before a late fee is added.

To pay a bill online, visit ipass.illinois.gov and select "Pay a Toll Bill." You will need the bill number (found on the notice you received) and your payment method. Payment is processed when ready, and you will receive a confirmation email. Paying online stops additional fees and prevents the bill from being sent to a collection agency.

If you plan to use toll roads regularly, opening an I-PASS account is more cost-effective than paying individual bills. However, if you only drive tolls occasionally, paying bills as they arrive is a valid option.

Understanding toll-by-plate and higher rates

Toll-by-plate is the system used when you drive through a toll plaza without a transponder and without having a prepaid account. The Illinois Tollway photographs your license plate and sends you a bill. Toll-by-plate rates are significantly higher than I-PASS rates—often double or more—because the state incurs costs to photograph, process, and mail the bill.

If you receive multiple unpaid toll-by-plate bills, the Illinois Tollway can place a hold on your vehicle registration renewal. This means you cannot renew your registration until the tolls are paid. The state can also refer the debt to a collection agency, which will report it to credit bureaus and may pursue legal action.

To avoid toll-by-plate charges, open an I-PASS account before you drive toll roads, or set up a toll-by-plate account on the Illinois Tollway website if you prefer not to use a transponder. A toll-by-plate account lets you prepay and receive a lower rate than the standard toll-by-plate charge, though it is still higher than I-PASS.

What happens if you do not pay tolls

Unpaid tolls do not disappear. The Illinois Tollway will send multiple notices, and if bills remain unpaid, the debt can be referred to a collection agency. At that point, the debt appears on your credit report and can affect your ability to borrow money or rent housing.

More when ready, unpaid toll bills trigger a registration hold. When you try to renew your vehicle registration with the Illinois Secretary of State, the system will flag the vehicle and deny renewal until the tolls are paid. This means you cannot legally drive the vehicle, and you risk a traffic stop if you do.

If you have unpaid tolls, paying them as soon as possible stops the collection process and removes the registration hold. You can pay through the Illinois Tollway website even if the bill is old or has been referred to a collection agency.

Setting up automatic payments and account notifications

Once you have an I-PASS account, you can set up automatic replenishment so that funds are added to your account automatically when the balance drops below a certain amount. This prevents your transponder from running out of funds and triggering toll-by-plate charges.

You can also set email or text notifications to alert you when your balance is low, when a payment is processed, or when your transponder needs replacement. These notifications help you stay on top of your account and avoid surprises.

To adjust these settings, log into your I-PASS account on ipass.illinois.gov, go to "Account Settings," and select your notification preferences. You can change them at any time.

Replacing or updating your I-PASS transponder

I-PASS transponders last about seven years before the battery dies. The Illinois Tollway will send you a notice when your transponder is nearing the end of its life. You can order a replacement transponder through your I-PASS account on ipass.illinois.gov at no charge (the original $25 fee covers the transponder for its lifetime).

If you move to a different vehicle, you can transfer your transponder to the new vehicle through your account. If your transponder is lost, stolen, or damaged, you can order a replacement for $25. Your prepaid balance transfers to the new transponder automatically.

Frequently Asked Questions

Can I pay tolls with a credit card at a toll plaza instead of online?

Most Illinois toll plazas no longer have staffed toll booths. You must either have an I-PASS transponder, pay online after receiving a bill, or set up a toll-by-plate account. A few plazas still accept cash at unmanned booths, but this is becoming rare. Check the Illinois Tollway website for current payment options at specific plazas.

What if I do not have a driver's license to open an I-PASS account?

You need a valid government-issued ID to open an I-PASS account. This can be a driver's license, state ID, passport, or military ID. If you do not have one of these, you can still pay individual toll bills by mail or through the Illinois Tollway website using your vehicle registration number.

How long does it take to pay a toll bill online?

Payment is processed when ready when you submit it through ipass.illinois.gov. You will receive a confirmation email within minutes. The payment removes the bill from your account and stops late fees from accruing. If you pay by mail, allow 10 to 14 days for processing.

Will paying my tolls online affect my credit score?

Paying tolls online does not affect your credit score. Only unpaid tolls that are referred to a collection agency appear on your credit report. Paying tolls on time, whether online or by mail, keeps your credit clean.

Can I use I-PASS in other states?

I-PASS works on toll roads in Illinois, Indiana, and Ohio through the IANA (Interagency Agreement). If you travel to other states with toll roads, you may need a separate transponder for that state's system, or you can pay toll-by-plate. Check the specific state's tollway website before traveling.
