  • 1 September 2025 – Third-Party Data Bi-Annual Submission period

    The SARS Third-Party Data Bi-Annual Submission process for the period 1 March 2025 to 31 August 2025 opens on 1 September 2025 and will close on 31 October 2025.

What is important to note?

  • Always use the SARS Test Platform that is open throughout the submission period. Doing so ensures that all your submitted data files are adequately tested for conformity with the External BRS requirements prior to being submitted to the SARS Live Platform. Always check the response code for the test and live submission. If the response code is 003 or 004, then your upload was successful.
  • Please make every effort to submit complete and accurate information on time, the first time around. Multiple revisions compromise the reliability of the data.
  • If you need to amend your submissions, please alert us of this before making the revisions. See these easy steps on How to correct or delete Third Party Data File.

Who is the Third-Party Data team?

The Third-Party Data team is part of Enterprise Data Management. This team acquires and harvests third-party data in accordance with Section 26 of the Tax Administration Act. This process requires approved third-party data providers such as banks, insurance companies, medical schemes, fund administrators, and other financial institutions to submit financial and personal information about taxpayers directly to SARS. The information collected includes interest earned (IT3b); disposal of financial instruments (IT3c); insurance payouts and contributions; medical expenses; pension and investment contributions; employee income; and FTI, as required under international information-exchange agreements. SARS uses this data to pre-populate individual tax returns, verify the accuracy of taxpayer submissions, and identify any discrepancies or risks. The submitted data also plays a critical role in enabling SARS to:

  • Pre-populate tax returns for individuals.
  • Improve overall taxpayer compliance.
  • Detect and prevent tax fraud.

SARS is committed to collecting complete, accurate, and timely third-party data, which is fundamental to a modern, transparent, and data-driven tax administration.

What Is Third-Party Data Submission?
