Form C-43 is used to revoke a written authorization for representation previously granted and on file with the Texas Workforce Commission (TWC).  Any business or employer that wants to revoke previously granted authority for an individual or service company to represent them in matters before TWC, can use this form. Also, the authorized representative or “grantee” may revoke their own authority to represent an employer in matters before TWC.

To request Form C-43, submit a Contact Request.  From the Employer menu, select:

  • Reason for Contact: Other Tax Issues
  • Issue that you are having: Employer Revocation of Third-Party Authorization (Form C-43) Issue

The revocation of written authorization must be signed by the:

  • Individual, if the grantor is a sole proprietor
  • Owner or an officer of an organization or a partner of a partnership
  • Fiduciary or trustee for a trust or estate
  • Grantee with Written Authorization (Form C-42) on file with TWC
