How To Register For SARS eFiling (2026 Guide)

SARS eFiling is the free online service for filing your tax return, checking your balance and getting tax certificates. Registering takes a few minutes if you have your details ready. Here is how to do it.

Do you already have a tax number?

Most employed South Africans are automatically registered for tax by their employer, so you probably already have a tax number even if you have never filed. You can find it on your IRP5 payslip certificate, or request it on the SARS website or the SARS MobiApp. You do not need to register for a tax number again, only for eFiling.

What you need before you start

  • Your South African ID number.
  • Your tax reference number (if you have one).
  • Your banking details.
  • A working email address and cellphone number for OTP verification.

How to register for eFiling, step by step

  1. Go to the SARS eFiling website and choose Register.
  2. Enter your ID number and personal details so SARS can match you to your tax record.
  3. Create a username and password.
  4. Verify your identity with the one-time PIN sent to your phone or email.
  5. SARS links your tax profile. If anything does not match, you may be asked to upload supporting documents.

Once registered, you log in any time to file returns, see assessments, and download a tax clearance or statement of account.

Filing season basics

During filing season, many taxpayers receive an auto-assessment from SARS based on data from employers and banks. If it is correct, you accept it and you are done. If something is missing, you file a return to correct it. Check the deadlines each year so you do not file late.

Frequently asked questions

How do I find my tax number? Check your IRP5 from your employer, log in to eFiling, or use the SARS MobiApp's "What's My Tax Number" feature. You can also request it by SMS or at a SARS branch.
Do I have to file a tax return? If you earn below the tax threshold from a single employer and have no other income, you may not need to file. If you have multiple income sources, deductions to claim, or were auto-assessed incorrectly, you should file.
Is SARS eFiling free? Yes. eFiling and the SARS MobiApp are completely free to use.

The verdict

If you are employed, you most likely already have a tax number, so registering for eFiling is the only step left, and it is quick. Get your ID, tax number and banking details ready, then register online. While you are thinking about tax, see how PAYE affects your pay with our salary calculator and read our tax brackets explainer.
