SARS issues GMT Registration and Notification – External Guide (GMT-REG-01-G01) on 15 May 2026, outlining eFiling registration requirements for the Global Minimum Tax under the Global Anti-Base Erosion (GloBE) framework, including use of the RAV01 form for subscription, amendments, notifications, and related updates.

The South African Revenue Service (SARS) has published the GMT Registration and Notification – External Guide (GMT-REG-01-G01) on 15 May 2026.

SARS has introduced the Global Minimum Tax (GMT) as part of South Africa’s implementation of the Global Anti-Base Erosion (GloBE) framework.

Registration for the Global Minimum Tax must be completed on the SARS eFiling system using the Registration, Amendments and Verification (RAV01) form. The RAV01 form enables a Domestic Constituent Entity (DCE), through its Registered Representative, to perform the following functions on eFiling via the GMT RAV01 form:

  •  Subscribe to the Global Minimum Tax (GMT) tax product.
  • Deactivate an active GMT tax product subscription.
  • Reactivate a previously deactivated GMT tax product subscription. iv) Amend GMT subscription information.
  • Submit GMT Notification Form.
  • Request correction against a submitted GMT Notification.

The Registered Representative must first activate their profile on eFiling before subscribing to a tax product and updating the taxpayer’s registered particulars using the RAV01 form.
