The Texas Protax sign-up portal is closed for 2018.

Don’t worry – it is not too late to sign up for our services! We are still taking on new clients by phone and email, but we recommend you file a protest yourself to ensure that the May 15th deadline is not missed.

Below are links to the Notice of Protests to be postmarked no later than May 15th:

Owners of Travis, Williamson & Hays County properties - Please call our Austin office at 512-339-6671 or email

Owners of Harris and Galveston County properties – Please call our Houston office at 713-635-9100 or email

Special Note for Hays County Property Owners: Since Hays County Notices of Appraised Value were not sent out until April 30th, the deadline to file a protest for Hays County properties is actually May 31st. Thank you, The Texas Protax Team
