Pay your EZ Tag Houston toll bill through the official Harris County Toll Road Authority website or by phone
EZ Tag is the toll collection system for Harris County toll roads in the Houston area. If you have an EZ Tag account, you can pay your toll balance online at www.harriscountytollroad.org, by phone at 281-875-3279, or through automatic payments set up on your account. The online payment method takes about five minutes and processes when ready.
You will need your EZ Tag account number to pay online. This number appears on your toll bill, on your EZ Tag transponder, or in your online account dashboard if you have already registered. If you do not have your account number, you can look it up on the Harris County Toll Road Authority website using your license plate number and vehicle information.

Steps to pay online through the Harris County Toll Road Authority website
Go to www.harriscountytollroad.org and look for the "Pay Now" or "Make a Payment" button on the homepage. Click it to enter the payment portal. You will be asked to enter your EZ Tag account number and the amount you want to pay, or you can choose to pay your full balance.
Enter your payment method — credit card, debit card, or bank account. The website accepts Visa, Mastercard, American Express, and Discover. If you are paying by bank account, have your routing number and account number ready. Review the payment details and confirm. The transaction will process when ready, and you will receive a confirmation number on screen and by email.
Keep your confirmation number for your records. Your toll balance will update within one business day, though most accounts update the same day. If you do not see the payment reflected after 24 hours, contact the Harris County Toll Road Authority at 281-875-3279 to confirm the transaction went through.
How to set up automatic payments so you do not have to pay manually
Automatic payments are the easiest way to keep your EZ Tag account current. You can set this up through your online account dashboard at www.harriscountytollroad.org. Log in with your account number and password, or create an account if you do not have one yet.
Once logged in, look for "Account Settings," "Billing," or "AutoPay" in the menu. Select the option to set up automatic payments. You will choose a payment method (credit card, debit card, or bank account) and decide whether you want the system to charge you a fixed amount each month or automatically pay your balance whenever it reaches a certain threshold.
Most account holders choose to have the system automatically pay their full balance each month. You can change or cancel automatic payments at any time through your account dashboard. If you cancel, you will go back to manual payments, so mark your calendar or set a reminder to pay before your balance gets too high.
What to do if you do not have an account number yet
If you drive Harris County toll roads but do not have an EZ Tag transponder or account, you can still look up any tolls you may owe. Go to www.harriscountytollroad.org and use the "Look Up Account" tool. Enter your license plate number and vehicle information. The system will show you any unpaid tolls associated with that plate.
If tolls are owed, you can pay them as a one-time guest payment without creating an account. However, if you drive toll roads regularly, opening an EZ Tag account is cheaper in the long run because account holders get a discount on each toll. You can open an account online, add a transponder to your vehicle, and set up a payment method all in one session.
To open an account, go to www.harriscountytollroad.org and select "Open an Account" or "New Customer." You will need your driver's license, vehicle registration, and a payment method. The transponder itself is free; you only pay for the tolls you use.
Payment methods accepted and any fees involved
The Harris County Toll Road Authority accepts Visa, Mastercard, American Express, and Discover for online payments. You can also pay by electronic bank transfer (ACH) if you provide your routing and account numbers. There is no fee to pay online with a credit or debit card, and there is no fee to pay by bank account.
If you pay by mail with a check, there is no fee, but mail payments take longer to process — typically 7 to 10 business days. If you pay in person at a payment location, there may be a small fee depending on the method. Paying online or setting up automatic payments is the fastest and most cost-effective option.
What happens if your toll balance is not paid
If your EZ Tag account balance remains unpaid, the Harris County Toll Road Authority will send you a bill in the mail. If you ignore the bill, the debt can be reported to a collection agency, and collection attempts may appear on your credit report. In some cases, the toll authority can place a hold on vehicle registration renewal or report the debt to the state.
If you receive a bill and cannot pay the full amount right away, contact the toll road authority at 281-875-3279 to discuss payment options. They may be able to set up a payment plan. Paying as soon as you can will prevent additional fees and collection action.
Frequently Asked Questions
Can I pay someone else's EZ Tag bill online?
You can pay another person's toll bill if you have their account number, but you will need to contact the Harris County Toll Road Authority directly at 281-875-3279 to arrange this. Online payments typically require the account holder's information, so a phone payment may be simpler for paying on behalf of someone else.
How long does it take for an online payment to show up in my account?
Online payments process when ready and you will receive a confirmation number right away. Your account balance usually updates within the same day, though it may take up to one business day. If you do not see the payment after 24 hours, call 281-875-3279 to verify it went through.
What if I entered the wrong account number when I paid online?
Contact the Harris County Toll Road Authority at 281-875-3279 as soon as possible. Provide your confirmation number from the payment. They can investigate where the payment went and help redirect it to the correct account or issue a refund if needed.
Can I pay my EZ Tag bill through a mobile app?
The Harris County Toll Road Authority does not have a dedicated mobile app for payments. You can pay through the website www.harriscountytollroad.org on your phone's web browser, or call 281-875-3279 to pay by phone. Both methods work on mobile devices.
Do I get a discount if I pay my full balance at once instead of monthly?
The toll discount applies to each individual toll you pass through, not to how you pay your bill. EZ Tag account holders pay a lower rate per toll than drivers without transponders. Whether you pay monthly, automatically, or in one lump sum does not change the per-toll rate.
