EZ Tag bills can be paid online through your account portal, by phone, by mail, or at a retail location — the fastest method is online through the Harris County Toll Road Authority website or mobile app, which processes payments when ready.

EZ Tag is the toll collection system used on Harris County toll roads in the Houston area. When you use a tolled road, the toll is charged to your account. If your balance drops below a certain threshold or you have an outstanding balance, you will receive a bill or notice. Understanding where and how to pay ensures you avoid late fees and service suspension.

The method you choose affects how quickly your payment posts and whether you can set up automatic payments. Each option has different timing and convenience trade-offs.

Paying Online Through Your EZ Tag Account

The Harris County Toll Road Authority website and mobile app are the primary channels for account management and payment. To pay online, log into your account at eztag.org, navigate to the payment section, and enter the amount you wish to pay. You can use a debit card, credit card, or bank account. Payments made before 11:59 p.m. typically post to your account by the next business day.

The online portal also shows your current balance, transaction history, and toll usage by date and location. This visibility helps you track spending and catch billing errors early. If you set up automatic replenishment, your account will charge your payment method when the balance falls below a threshold you set — usually between $10 and $100. Automatic replenishment can reduce your toll rate by up to 10 percent on certain Harris County toll roads.

If you forget your login credentials, the website offers a password reset option. You will need your account number, which appears on your bill or toll notice.

Paying by Phone

You can pay your EZ Tag bill by calling the Harris County Toll Road Authority customer service line. The phone number is printed on your bill or toll notice. Have your account number, the amount you wish to pay, and a debit or credit card ready before you call. The representative will process your payment over the phone and provide a confirmation number.

Phone payments typically post within one to two business days. This method is useful if you do not have internet access or prefer to speak with a representative about your account. However, phone lines can have wait times during peak hours, particularly early morning and late afternoon on weekdays.

Paying by Mail

You can mail a check or money order to the address listed on your bill. Include your account number on the check and mail it to the Harris County Toll Road Authority payment processing center. Mail payments take seven to ten business days to arrive and post, so do not use this method if your account is close to suspension or if you have a court date related to unpaid tolls.

Keep a copy of your check or money order receipt for your records. If your payment does not post within two weeks, contact customer service with your receipt information to trace the payment.

Paying at Retail Locations

Some HEB and Kroger locations accept EZ Tag payments in cash or by card at customer service desks. Not all locations offer this service, so call ahead or check the Harris County Toll Road Authority website for a list of participating retailers near you. Retail payments do not post in real time — they are batched and processed, which can take three to five business days.

Retail payment is most useful if you prefer to pay in cash or do not have online or phone access. However, you will not receive an when ready confirmation that your payment has been applied to your account, so follow up online or by phone after a few days to verify posting.

What Happens If You Do Not Pay

If your EZ Tag account balance remains unpaid past the due date on your notice, the Harris County Toll Road Authority may suspend your account, preventing the tag from working on toll roads. A suspended account can also result in late fees and collection action. If your account is suspended, you must pay the full outstanding balance plus any fees before the tag will function again.

Unpaid toll debt can also be reported to credit bureaus and may affect your ability to renew your vehicle registration. If you receive a toll violation notice or collection letter, contact the Harris County Toll Road Authority when ready to discuss payment options or dispute the charge if you believe it is incorrect.

Setting Up Automatic Payments

Automatic replenishment is the most reliable way to keep your account current. Log into your EZ Tag account online, select the automatic payment option, and choose your preferred balance threshold and payment method. Once set up, your account will automatically charge your card or bank account whenever the balance drops below your chosen amount.

Automatic payments also may have access to you for a toll rate discount on most Harris County toll roads — typically 10 percent off the cash toll rate. This discount applies only if you maintain active automatic replenishment. You can change or cancel automatic payments at any time through your online account.
