By | July 15, 2025

Need to find your SARS tax number? Whether you’re starting a new job, registering a business, or applying for financial products, having a tax number is essential in South Africa. The good news is that you can get your tax number online using the SARS eFiling system; no need to stand in queues at a branch.

Here’s a step-by-step guide on how to get your SARS tax reference number online.


Step 1: Visit the SARS eFiling Website

Start by going to the official SARS eFiling portal:
www.sarsefiling.co.za

This is the online platform provided by the South African Revenue Service to help individuals and businesses manage their tax affairs conveniently.


Step 2: Register for an eFiling Profile

If you’re not yet registered, click the “Register” button on the homepage.

You’ll need to provide:

  • Your South African ID number
  • Full name and surname
  • Contact details (mobile number and email)
  • A secure username and password

Make sure the information matches your official documents to avoid verification issues later.


Step 3: Activate and Log Into Your Account

Once your registration is complete, you’ll receive an activation link or code via SMS or email.

After activating your eFiling account, log in using the username and password you created.


Step 4: Go to the “My Details” Section

Once logged in, look for the menu or dashboard option that says “My Details” or “Taxpayer Information”.

This section will show your registered personal information, including your name, ID number, and contact details.


Step 5: Request or Retrieve Your Tax Number

If you’ve already been registered for tax by SARS, your tax number will appear automatically under your profile details.

If your profile doesn’t show a tax number, follow these steps:

  • Click on “Register for Tax” or “Request Tax Reference Number”
  • Complete the online form with your personal details
  • Submit your request to SARS through the platform

Step 6: Wait for SARS Confirmation

Once submitted, SARS may take a short time to verify your identity and register your tax number. They may ask for:

  • A copy of your South African ID
  • Proof of residence
  • Additional supporting documents (in some cases)

Keep checking your eFiling inbox, SMS messages, or email notifications for updates.


Step 7: Receive Your Tax Number

After successful verification, SARS will send your tax reference number via the communication method you selected during registration. It usually comes via SMS or email.

Make sure to save it somewhere safe; you’ll need it for all tax-related matters going forward.
