Texas Renewal/Amendment of Purchasing Group Registration — Form PG1R is a Texas Comptroller of Public Accounts form that is used by purchasing groups to renew or amend their registration with the State of Texas. The form is used by purchasing groups who are registered with the state and who are wishing to change or update their registration information. There are two types of forms available: Renewal and Amendment. The Renewal form is used to submit an annual renewal of the group’s registration, and the Amendment form is used to update the group’s registration information, such as contact information or list of members. Both forms must be completed and signed by an authorized representative of the purchasing group, and must be submitted to the Comptroller of Public Accounts.
