Helpful Information About the Texas Universal Service Fund

If you have received a letter regarding the Texas Universal Service Fund (TUSF) assessment, it is because you have been identified by the Texas Comptroller’s office as an entity that reports taxable telecommunications receipts under Chapter 151 of the Texas Tax Code. The TUSF is supported by a charge of about 12% of all taxable telecommunications receipts of Texas’ telecommunications providers.

If you believe that you are not a telecommunications provider as that term is defined below, please send a letter briefly stating the basis for the assertion that you are not a telecommunications provider. Your letter will assist us in maintaining accurate records.

Send your letter to the following address:

The Public Utility Commission hired an outside entity to administer the TUSF because the PUC does not have sufficient in-house resources or expertise to manage the daily operations of the fund. For questions regarding the TUSF contact Solix's TUSF hotline at  (800) 899-6078.

Solix was selected as the TUSF administrator through a competitive bidding process because it offered the best package of services at the best price. Solix serves as the administrator for at least six other state universal service funds.

If you still have outstanding questions after contacting the Solix, please notify the TUSF Administrator at the Public Utility Commission of Texas.



In 1987, the Texas Legislature established a Universal Service Funding mechanism, which has changed over time through amendments to the Texas statute. The current rules concerning universal service in place at the Public Utility Commission of Texas complement the federal universal service rules and are appropriate for the changes in the telecommunications industry toward a competitive market.

The Texas Universal Service Fund (TUSF) is financed by a charge of 12% of all taxable telecommunications basic service receipts of Texas' telecommunications providers. At the May 11, 2023 open meeting, the Commissioners approved reducing the TUSF assessment rate from 24% to 12% effective July 1, 2023. Telecommunications providers are not required to pass the costs of the TUSF through to residential and business customers on their monthly bills, but they may choose to do so. Currently, the TUSF supports several programs: the Relay Texas and Specialized Telecommunications Assistance Programs, the Tel-Assistance, Lifeline and Link Up programs, and the Small Local Exchange Carriers Universal Service Fund, and the Texas High-Cost Universal Service Plan.
