How to Pay Your Kansas Turnpike Toll

Kansas Turnpike payment methods and where to send money

The Kansas Turnpike Authority accepts payment by mail, online, by phone, and at toll plazas. If you drove through a toll plaza without paying, you will receive an invoice in the mail—usually within two weeks. You can pay that invoice immediately or set up a payment plan. The Kansas Turnpike does not use license plate readers to bill you later; you either pay at the booth or receive a bill.

Most drivers pay one of two ways: they stop at a toll booth and hand cash or a card to an attendant, or they receive an invoice by mail and pay it before the due date. A small number of regular users open a prepaid account called a K-Tag, which deducts tolls automatically as you pass through.

Key Takeaways

• If you did not pay at a toll plaza, the Kansas Turnpike Authority will mail you an invoice within two weeks; pay it by the due date to avoid late fees.
• You can pay an invoice online at ksturnpike.org, by phone at 1-888-511-8735, by mail, or in person at a toll plaza.
• A K-Tag account lets regular users prepay and pass through toll plazas without stopping, though the account requires a deposit and monthly maintenance.
• Late payment fees and collection actions begin if you ignore an invoice; the Turnpike Authority can suspend your vehicle registration.

Paying an invoice you received in the mail

When you receive a toll invoice, it will show the toll amount, the date you passed through, and a due date—usually 30 days from the date the invoice was mailed. Pay by that date to avoid a late fee. The invoice will list four payment methods: online, by phone, by mail, or in person at a toll plaza.

Online payment is the fastest. Go to ksturnpike.org, select "Pay a Toll Invoice," and enter the invoice number and the amount due. You can pay with a debit card, credit card, or electronic check. Payment is processed immediately, and you will receive a confirmation number on screen and by email.

By phone, call 1-888-511-8735 during business hours (Monday through Friday, 8 a.m. to 5 p.m. Central Time). Have your invoice number and a debit or credit card ready. By mail, send a check or money order to the address printed on your invoice. By in-person, visit any toll plaza during operating hours and pay the attendant with cash or a card.

What happens if you miss the due date

If you do not pay by the due date, the Kansas Turnpike Authority will add a late fee to your balance. The amount of the late fee varies but typically ranges from $10 to $25 per unpaid invoice. You will receive a second notice in the mail with the new total due and a new deadline.

If you ignore the second notice, the Turnpike Authority can refer your account to a collection agency and report the debt to credit bureaus. More seriously, they can request that the Kansas Department of Revenue suspend your vehicle registration, which means you cannot legally drive the vehicle until the toll debt is paid and the suspension is lifted. This process can take several weeks even after you pay.

If you receive a collection notice or a suspension warning, contact the Kansas Turnpike Authority immediately. You may be able to negotiate a payment plan or settlement, especially if you can show the invoice was lost or you had a genuine hardship.

Opening and using a K-Tag prepaid account

A K-Tag is a small electronic device mounted on your windshield that deducts tolls automatically as you pass through toll plazas. You do not have to stop or hand money to an attendant. K-Tag holders also receive a small discount on each toll—usually 10 to 15 percent—compared to paying cash at the booth.

To open a K-Tag account, visit ksturnpike.org or call 1-888-511-8735. You will need a valid driver's license, a vehicle registration, and a debit or credit card. There is an initial deposit (typically $25 to $50) and a monthly account maintenance fee (usually $1.50 to $2.00). The deposit sits in your account and is drawn down as you use the turnpike; you replenish it when it falls below a certain threshold.

K-Tags are most useful if you drive the Kansas Turnpike regularly—at least a few times per month. If you drive it rarely, the monthly fee will cost more than you save on tolls. You can close a K-Tag account at any time and receive a refund of any remaining balance, minus any outstanding tolls or fees.

Toll rates and which roads charge tolls

The Kansas Turnpike is a 236-mile highway that runs north to south across Kansas, from the Oklahoma border to the Nebraska border. Tolls are charged at multiple plazas along the route. The toll amount depends on how far you travel; a short trip might cost $2 to $3, while a trip across the entire turnpike can cost $15 to $20. Exact rates are posted at ksturnpike.org and at each toll plaza.

Kansas has no other toll roads. All other state highways and interstates are free. If you are unsure whether a road charges a toll, check the road signs as you approach it or look up the route on ksturnpike.org before you drive.

Disputing a toll charge or invoice

If you believe you were charged incorrectly—for example, you paid at the booth but still received an invoice, or you were charged twice for one trip—contact the Kansas Turnpike Authority in writing or by phone. Call 1-888-511-8735 and explain the issue. Have your invoice number, the date of travel, and any receipt or proof of payment ready.

The Turnpike Authority will investigate and respond within 10 to 15 business days. If they confirm the error, they will issue a credit to your account or a refund. If you disagree with their decision, you can request a formal review, though this process is lengthy and rarely overturns the initial decision.

Frequently Asked Questions

Can I pay a toll invoice with a personal check?

Yes. Mail a check or money order to the address on your invoice. Include the invoice number on the check. Processing takes 5 to 10 business days after the Turnpike Authority receives it, so mail your payment early to avoid a late fee.

What if I lost my invoice?

Call 1-888-511-8735 and provide your license plate number or vehicle information. The Turnpike Authority can look up your account and tell you the amount due and the due date. You can pay over the phone or ask them to mail a new invoice.

Do I have to use a K-Tag, or can I always pay at the booth?

K-Tags are optional. You can always stop at a toll booth and pay cash or card. K-Tags are a convenience for frequent users; they are not required.

Will a toll debt affect my credit score?

Not immediately. But if the debt goes to a collection agency and is reported to credit bureaus, it will appear on your credit report and lower your score. Paying the debt before it reaches collections protects your credit.

Can I pay someone else's toll invoice?

Yes. You can pay any toll invoice as long as you have the invoice number and amount due. You do not have to be the vehicle owner or the driver. Pay online, by phone, or by mail using the methods listed on the invoice.
