By | July 30, 2025

Need a South African tax number? Whether you’re starting your first job, freelancing, or registering a business, getting a tax number from SARS (South African Revenue Service) is a must. Here’s a step-by-step guide to help you apply online with ease.

Step 1: Decide What Kind of Tax Number You Need

SARS issues different tax numbers depending on your situation:

  • Individuals need an Income Tax Number.
  • Businesses and other entities need a Tax Reference Number (TRN).

Make sure you know which one applies to you before you begin.

Step 2: Prepare Your Documents

Before applying, gather the following:

  • Proof of identity (SA ID, passport, or asylum document)
  • Proof of address (e.g., utility bill or lease agreement)
  • For businesses: additional documents like CIPC registration details may be required.

Step 3: Register on SARS eFiling

To apply online, you must first register on the SARS eFiling platform:

  1. Visit www.sarsefiling.co.za
  2. Click on Register and follow the prompts.
  3. Choose the correct registration type (individual or business).
  4. Complete your personal or company details accurately.

Already have an eFiling profile? Simply log in and proceed to add an income tax type.

Step 4: Submit Your Tax Number Request

Once registered, you can apply for a tax number directly through your eFiling dashboard. You’ll either be:

  • Automatically issued a tax number based on your registration, or
  • Prompted to upload supporting documents for SARS to verify your information.

Step 5: Verification and Processing

SARS will review your application and may request additional documents if needed. Processing can take a few days to a week, depending on the accuracy of your submission and how busy the system is.

Step 6: Receive Your Tax Number

Once approved, your unique SARS tax number will be sent to you via:

  • Email
  • SMS (if you provided a mobile number)
  • Or visible in your eFiling profile

Pro Tip:

To speed things up, double-check that all your documents are clear and up to date before submission. Mistakes or missing info often delay the process.
