Why am I getting multiple bills for Austin tolls?

The Austin area has two toll authorities with separate toll billing systems and policies:

  • TxDOT/TxTag
  • Central Texas Regional Mobility Authority (Mobility Authority)

If you do not have a prepaid TxTag, TollTag, EZ TAG, K-TAG, or PIKEPASS and you drive on Austin-area toll roads, you might receive two separate statements. You could receive one statement from TxTag and one from the Mobility Authority, depending on what roads you drive. You must pay the amount due on both bills.

I have a TxTag account, so why did I get a statement with Pay By Mail tolls?
If you have a TxTag account but you do not have enough money in your tag account to cover your tolls, you will receive a statement in the mail that includes tolls charged at the higher Pay By Mail rates. The statement will also include a mailing fee. You will continue to be charged at the Pay By Mail rates until your TxTag account is replenished. By signing up for AutoPay, your account will be automatically replenished when it gets to a preset low balance amount.

You could also receive a Pay By Mail statement if your TxTag was not detected on the toll road and your license plate does not match an existing tag account. Contact the TxTag Customer Service Center to update your tag account information by visiting TxTag.org or by calling 1-888-468-9824.
