Welcome to the Texas Administrative Code

The Texas Administrative Code (TAC) is a compilation of all state agency rules in Texas. There are 17 titles in the TAC. Each title represents a subject category and related agencies are assigned to the appropriate title.

In 1977, the TAC was created by the Texas Legislature under the Administrative Code Act (Government Code, §§2002.051-2002.056). In the Administrative Code Act, the Legislature directed the Office of the Secretary of State to compile, index, and cause to be published the Texas Administrative Code.

State agency rule writers, in cooperation with the Office of the Secretary of State, had begun the task of organization and systematic dissemination of state agency rules in 1975 with the passage of the Administrative Procedure and Texas Register Act (Government Code, §2001 and §2002).

With the passage of the Administrative Code Act, the Legislature intended for the Secretary of State to contract with public entities to publish the TAC. However, as more innovative technology became available, demand for the TAC in electronic format increased. In response to this increased demand, HB 2304 was passed by the Texas Legislature in 1995. HB 2304 allows the Secretary of State to make the TAC available through our web site and to charge for value-added services available through the web site.

In addition, HB 2304 mandated that the TAC be made available in an electronic format at no charge. This complimentary service is available using the TAC Viewer.
