How to Get Your Tax Number


The tax identification number is issued exclusively by the South African Revenue Service (SARS) when an individual or corporate entity registers for it. It does not have an expiration date and is found on all forms of documents or mails addressed to a taxpayer.  

In this article, we will discuss how to get your tax number

Register for a tax number manually.

Take the following documents to a SARS branch to get your tax number and register as a taxpayer. 

  • A true certified copy of your South African ID card, passport, or driver’s license. 
  • The latest original bank statements have been stamped by the bank and dating up to 3 months back. 
  • Proof of your current address on a document that has an official letterhead. 
  • What happens next? 

Generally, SARS will register you into their system as a taxpayer and provide your tax number on the spot. You may receive your tax number through the post after your registration.
