Mobility Authority roads are modern, all-electronic toll roads, meaning drivers don’t have to stop — or even slow down — to pay their tolls. Customers can either pay through their electronic tag account or pay by mail.

What is an electronic tag?

Electronic tags are an electronic payment method that automatically pays for tolls as you drive on toll roads.

Once you sign up for an electronic tag (see accepted tags below), the tag provider will then send a tag that you mount to the inside of your windshield behind the rearview mirror. When you drive on a tolled facility, an electronic reader above the toll road will read the microchip inside the tag and cameras take a photo of your license plate.

If you have an active account (information is up-to-date and sufficiently funded), the price of the toll will be debited from your account. Toll roads in Texas are interoperable, meaning all toll transactions should appear on one invoice. 

Electronic tag customers receive a 33% discount over Pay By Mail bills. 

The Mobility Authority currently accepts NTTA’s TollTag, HCTRA’s EZ TAG, TxDOT’s TxTAG, Kansas Turnpike Authority's K-Tag, Oklahoma Turnpike Authority's Pikepass and BancPass/PlusPass. The Mobility Authority is continuously working to become interoperable with other agencies.

*Please note, different electronic tags may need to be installed differently. Check with your tag provider for instructions. 

Where can I get an electronic tag?

The Mobility Authority is not a tag provider. We accept several electronic tags on our facilities, you can visit their website to learn more and to sign up for a tag. See below for a list of electronic tags we accept. Any of these tags will work on all Texas toll roads. 

TollTag from the North Texas Tollway Authority in the Dallas area

EZ Tag from the Harris County Toll Road Authority in the Houston area

TxTag from the Texas Department of Transportation in the Austin area 

K-Tag from the Kansas Turnpike Authority in Kansas 

Pikepass from the Oklahoma Turnpike Authority in Oklahoma 

The Mobility Authority also accepts the PlusPass app. 

Electronic tag customers receive a 33% discount over Pay By Mail bills. 

What is a Toll Bill and why did I receive one?

Toll bills are received by drivers who use Central Texas toll roads without having an active electronic tag account.  

Toll bills are part of the Pay By Mail program. Equipment on the toll road takes a picture of a vehicle’s license plate, and that information is used to identify the registered owner of the vehicle. A toll bill is then sent to the registered owner’s address.

If you received a toll bill, a vehicle registered in your name has recently travelled on a Central Texas toll road. Be aware that if you lease or loan your vehicle to someone else, Texas law dictates that the registered vehicle owner is responsible for paying any tolls incurred on that vehicle. Failure to pay a toll bill can result in additional fees and criminal charges.

Toll rates for Pay By Mail customers are higher than for drivers with a tag to offset the cost of processing license plate information and mailing the toll bill. In addition, each bill comes with a $1.00 processing charge.

Pay By Mail customers have 30 days to pay their bill before late fees are assessed. Customers can pay their bill via mail, online by visiting PayMobilityBill.com, in person, or call (833) 762-8655.

Depending on which toll roads you use, you may be issued toll bills from separate operating agencies.

Account Questions - Beginning May 1, 2022

Since November 2020, I have a TxTag but I got a bill from you – why?

This response is specific to TxTag, if you have a different accepted electronic tag, check your account with your tag provider.

Although you had an active TxTag at one time, TxTag has declined payment for certain transactions on Mobility Authority roads, which has resulted in you receiving a Pay By Mail bill. Since TxTag changed backoffice providers (a backoffice provide is the third-party company responsible for consolidating toll transactions, sending your toll bill and taking your payment), TxTag has experienced data issues and as a result, many TxTag customers became Mobility Authority Pay By Mail customers. As a reminder, TxTag is not owned nor operated by the Mobility Authority and the Mobility Authority does not have access to TxTag account details.

When a driver uses our roads, toll gantries use radio frequency technology to “read” a transponder, in this case TxTag. If a TxTag is detected on the vehicle, the Mobility Authority sends the information to TxTag, who then either accepts the transaction and it posts to the users’ TxTag account, or declines the transaction. The Mobility Authority typically resubmits the declined transaction three times in a good faith effort to ensure the rejection is accurate. For this round of bills, as additional quality control, we have submitted the transactions a fourth time, and have still received a decline from TxTag.

The Mobility Authority doesn’t have access to TxTag’s system, so we can’t see why a transaction was declined, only that it was declined. There are several reasons a transaction might be declined, so we encourage all TxTag customers to log into their TxTag account at TxTag.org to ensure their account has a positive balance; a valid payment method is associated with the account; the license plate is correct; the correct tag is matched to the license plate; and the tag is valid (not labeled damaged or lost but still associated with the vehicle) to ensure their accounts are in good standing to avoid receiving a Mobility Authority Pay By Mail bill in the future.

We cannot retroactively add transactions to a TxTag account. All Pay By Mail bills will need to be paid to the Mobility Authority directly.

Why am I just receiving this toll bill when I have not been billed in previous months, with some of the transactions being older than 30 days? If there was an issue with my account, wouldn’t I have been billed before now?

TxTag has experienced data issues since changing back-office providers. The Mobility Authority paused billing all electronic tag transactions declined for payment by TxTag to allow time for TxTag quality control issues to be resolved. TxTag has assured us, and other Texas toll agencies, that those quality control issues have been resolved and any declined transactions from their system are appropriate. Based on this assurance, we have resumed Pay By Mail billing for transactions incurred beginning May 1, 2022. This pause impacted all tag transactions that were declined by the tag provider, including TollTag and EZ Tag. As an added quality control measure, the Mobility Authority submitted your transactions four times over a period of several weeks rather than the standard three submittals, and the transactions were declined by the tag provider each time.

The Mobility Authority doesn’t have access to your tag provider’s system, so we can’t see why a transaction was declined, only that it was declined. There are several reasons a transaction might be declined, so we encourage all tag customers to log into their tag account online to ensure their account has a positive balance, the license plate is correct, a valid payment method is associated with the account, the correct tag is matched to the license plate, and the tag is valid (not labeled damaged or lost but still associated with the vehicle) to ensure their accounts are in good standing and avoid receiving a Mobility Authority Pay By Mail bill in the future.

I have a tag account. Why do I have to pay a higher toll rate?

As mentioned above, we don’t have access to your tag provider’s system so we can’t see why your tag provider declined the transaction, resulting in a Pay By Mail bill. Please contact your tag provider to learn more about your account status.

Why do I have to pay the Mobility Authority directly? Why can’t you just debit from my tag account?

Before sending a Pay By Mail invoice, the Mobility Authority attempted to post this toll to your tag account four times. Each time your tag provider declined payment. The Mobility Authority is a separate agency from your tag provider, and we do not have the ability to access your account to retroactively process charges, nor can we see why a transaction was declined by your tag provider.

How do I confirm there are no additional charges or late fees assessed?

Due to the volume of transactions we are invoicing and the different background processes involved, it is possible for charges to be delayed. We encourage customers to monitor this situation at paymobilitybill.com and to sign up for electronic notification of any new bills so that you won't miss any payment deadlines. Paying your bill by the due date will ensure no late fees are charged. Please contact your tag provider if you have any questions about your electronic tag account status.

I received an incorrect bill. How did that happen?

First, make sure no one else was driving your vehicle. As noted above, toll payment processors can only charge the owner of the vehicle, so if someone in your family or a friend was driving your vehicle, you will still get the bill. Keep in mind that you may receive a Pay By Mail bill if your electronic tag account is not active (up-to-date information and funded). If you feel you have received a bill in error or received the same bill twice, call the customer service number toll-free at (833) 762-8655 or (512) 410-0562.

Why can't I pay cash on Mobility Authority facilities?

Cashless (or all-electronic) toll collection has been implemented on toll roads throughout Central Texas. Cashless toll collection is more cost effective, improves safety, speeds up traffic, reduces vehicle emissions, and conserves fuel by eliminating the need to stop and pay a toll. It also makes the toll you pay cheaper. Although cash payment at toll booths on the roadway is not offered, customers who prefer to pay their tolls in cash can still do so in the following ways:

  • Pay your Pay By Mail toll bills in person at any ACE Cash Express store location nationwide. Click here to find the store nearest you.
  • Fund your TxTag account in person at the TxTag Customer Service Center, located at 12719 Burnet Road, Austin, TX 78727.
