What are Biennial Fees?

Biennial fees are required as described by 25 Texas Administrative Code, §289.204 - Fees for Certificates of Registration for all X-ray certificates of registration. These fees are used to cover all direct and indirect costs associated with licensing a company or individual. (i.e., any future amendments within the noted billing period, costs associated with required inspections of your license/registration, standard operating costs, etc.). 

These required fees will be billed approximately 60 days prior to the fees being due. These bills should be paid in a timely manner, or your registration could be revoked, which can result in penalties and fines. 

How do Biennial Fees Differ from Technical Renewal?

While biennial fees require payment every two years, technical renewal typically occurs every 8-10 years and requires re-submission of all appropriate forms, procedures, and fees. 

New certificates of registration are not issued for payment of biennial fees.
