Missed the 23 October 2026 SARS deadline, or still need to file? You can still submit your return on eFiling, though SARS can charge penalties on late returns. Provisional taxpayers have until 22 January 2027.

The steps are the same either way: check whether SARS has auto-assessed you, log in, open your ITR12, fill in what's missing and submit. Dates are from SARS's filing season page.

Do you need to submit a tax return at all?

Yes, if you earn more than R500,000 a year, or if any part of your income doesn't come cleanly through one employer's PAYE. Below that, you're only exempt if every one of four conditions applies to you.

SARS says you don't have to file if all of these are true: you have one source of income (one employer, one salary), you got no travel allowance or company car, you have no other income at all (no interest, rent or side hustle), and your employer took off the right PAYE all year (SARS Filing Season). Say you're an admin assistant in Durban earning R320,000 a year from one employer with nothing else coming in. You're probably exempt. But as soon as you add a weekend side hustle, a rental flat in Mitchells Plain or interest above the tax-free limit on a savings account, you must file, even if your salary alone is under R500,000. For every condition and what rules you out, see our guide on who needs to submit a SARS tax return. If your side hustle is growing, compare staying a sole trader with registering a company with CIPC, which you can do online for as little as R125. If the side hustle is a shop rather than freelancing, see our guide on starting a spaza shop in South Africa for the registration, tax and funding rules for small shops. A SASSA grant you receive, or collect for a child or older relative, doesn't count as income for this test: see our guide to SASSA grant amounts for the current figures. Rules differ a lot across the region: Tanzania's PAYE, for example, is deducted monthly by the employer using TRA's own bands, not SARS's.

Don't guess. If SARS's system shows a return as outstanding, it doesn't matter that you thought you were exempt. The penalty starts anyway. Log into eFiling and check your compliance status if you're not sure.

What's new for the filing season

  • More prefilled data. SARS now pulls in more third-party information (IT3(t) data, investment income, medical aid details) before you open your return, so there's less manual capturing (SARS, Changes for Filing Season 2026).
  • Simpler questions and a medical aid dropdown, meant to cut the mistakes people make selecting the wrong scheme.
  • WhatsApp channel. You can now view your Notice of Assessment (ITA34) and Statement of Account, and upload supporting documents, through SARS's WhatsApp number (0800 11 7277) instead of only through eFiling.
  • Biometric facial recognition has been added to the eFiling login process for some users, alongside the usual one-time pin (OTP) (SARS eFiling guide).
  • More provisional taxpayers are being auto-assessed this year for the first time, not just salaried employees (SARS, Changes for Filing Season 2026).

At the season's opening on 2 July 2026, SARS reported that over 1.9 million taxpayers had already received an auto-assessment, with about R8 billion in refunds paid out within 72 hours, and it expects more than six million people to be auto-assessed in total this year (SARS media release).

Documents to gather before you start

Have these ready. eFiling goes faster and you'll make fewer mistakes:

  1. IRP5/IT3(a) certificate(s) from every employer you worked for in the tax year.
  2. Medical aid tax certificate showing your contributions and any out-of-pocket medical expenses.
  3. Retirement annuity or pension fund certificate (IT3 certificates from your RA or provident fund).
  4. Investment income certificates (IT3(b)) from your bank or unit trust provider.
  5. Bank details. SARS can't pay a refund into an account it hasn't verified.
  6. Travel logbook if you claim a travel allowance.
  7. Records of any other income: freelance invoices, rental income and expenses, foreign income, capital gains on property or shares.
  8. Your tax reference number and ID number.

Keep all of it for five years, because SARS can ask for supporting documents after you've filed (SARS, how to submit an ITR12).

How to register and log in to SARS eFiling

  1. Go to eFiling. Register at sarsefiling.co.za or download the SARS MobiApp if you'd rather file from your phone.
  2. Accept the terms and conditions when you first log in. Read them, scroll to the bottom and select "I Accept".
  3. Confirm your security contact details (cellphone number or email) so SARS can send you a one-time pin.
  4. Complete or confirm your personal details, then click "Next."
  5. Pass facial recognition authentication if prompted, then choose your preferred channel (SMS or email) for the OTP and enter the last six digits sent to you.
  6. Land on your eFiling dashboard. From here you can see your Notice of Assessment, Statement of Account and Tax Compliance Status at a glance (SARS eFiling guide).

If your profile is flagged as inactive, belongs to a deceased estate, or shows multiple tax numbers, eFiling will tell you to sort it out at a SARS branch before you can file.

How to submit your ITR12 step by step

  1. Check for an auto-assessment first. If SARS has already assessed you, you'll see it on your dashboard or get an SMS/email between 1 and 12 July. Read the section below before doing anything else.
  2. Open your return. Click "Returns" → "Returns Issued" → "Personal Income Tax (ITR12)," select tax year "2026," and click "Request Return" if it hasn't already been issued to you (SARS eFiling guide).
  3. Go through the wizard. A short questionnaire sets up your ITR12 for your situation. Answer honestly about freelance income, rental property, foreign income and so on, because it decides which sections appear.
  4. Refresh and check the pre-filled figures. Your IRP5 income, PAYE deducted, medical aid and RA contributions should already be there. Compare every figure with your own certificates before you trust it. Our South Africa income tax calculator shows roughly what your PAYE should be for the 2026/27 tax year if you want a quick check.
  5. Declare anything that isn't pre-filled. Freelance or side-hustle income, rent, foreign income and capital gains don't always come from third parties, so add them yourself in the right section. If that freelance or side-hustle income is regular, check whether it also makes you a provisional taxpayer who must pay SARS twice a year, not just file once.
  6. Add your deductions. Retirement annuity contributions, additional medical expenses and (if it applies) home office costs go here.
  7. Save as you go. Click "Save" at any point so you don't lose your work if you get interrupted.
  8. Submit. Once everything's captured, click "Submit return to SARS," check the pre-populated date on the Declaration screen, and click "Confirm" (SARS eFiling guide).
  9. Wait for your ITA34. You'll get a Notice of Assessment showing whether you're due a refund or owe SARS money. You can see it on eFiling, the MobiApp or WhatsApp.

If you'd rather not do it yourself, freelancers and anyone with side income can use a registered tax practitioner. Unregistered "practitioners" can still prepare your return, but they can no longer submit it for you.

How SARS auto-assessment works

SARS auto-assesses you if your income is simple, mainly salary and investment income reported to SARS by employers, banks, medical schemes and retirement funds, and your personal details are up to date (SARS, how auto-assessment works). You won't be auto-assessed if you have rental income, freelance income or other income SARS can't check from those sources.

  • If you agree with it: do nothing. There's no "accept" button, and the assessment simply becomes final. A refund of R100 or more is paid within 72 hours, and smaller amounts carry over to next year.
  • If you disagree: open your return on eFiling or the MobiApp from 13 July, add whatever's missing, and submit a full ITR12 by 23 October 2026 (22 January 2027 if you're an auto-assessed provisional taxpayer). This replaces the auto-assessment with your corrected version.
  • If you owe money: debts of R100 or more must be paid by the due date on your assessment, and interest accrues on anything outstanding regardless of amount.

Check your bank details are up to date before the season opens, because SARS can't pay a refund into an account it can't verify.

Medical aid and retirement annuity deductions

Two deductions catch out a lot of first-time filers, so check these against your own certificates rather than assuming eFiling got it right.

Medical scheme fees tax credit for the 2026 tax year (1 March 2025 – 28 February 2026, the year you're filing now) is a fixed monthly amount, not a percentage:

Who Monthly credit
Main member R364
First dependant R364
Each additional dependant R246

Source: SARS, Medical Tax Credit Rates. These come on top of any additional medical expenses credit if your own medical costs were high compared with your income. The credit is the same fixed amount whether you're on a cheap hospital plan or a full medical aid. See our breakdown of medical aid, hospital plans and gap cover costs if you're still deciding which suits your budget.

Retirement annuity and pension contributions are deductible up to the lowest of three amounts: R350,000 a year, 27.5% of the higher of your pay or taxable income, or your taxable income before capital gains (SARS, section 11F FAQ). Anything above that limit isn't lost. It carries forward and can be deducted in a later year. Note that the higher R430,000 cap only starts with the 2026/2027 tax year, from 1 March 2026, so it doesn't apply to the return you're filing this season. Don't let news about the new cap lead you to claim too much now. If you took money out of your retirement fund's two-pot savings pot during the year, that withdrawal isn't a deduction. It's added to your taxable income and taxed at your normal rate, so read our guide on two-pot withdrawals and tax before you file. A tax-free savings account works differently again: there's no deduction for what you put in, but the growth is never taxed. See our guide to the best TFSA in South Africa if you're comparing it with an RA.

Common eFiling mistakes

  • Missing the deadline is expensive, even if you owe nothing. SARS charges an administrative penalty of R250 to R16,000 a month for an outstanding return, scaled to your taxable income, for up to 35 months (SARS, Admin Penalty). It applies from your first missed return going back to 2007 if SARS's records show you have one outstanding. See how that penalty is calculated, and what to do if you've already missed the 23 October cut-off, in our guide on what happens if you miss the SARS deadline.
  • Thinking you're exempt when you're not. The R500,000 threshold only holds if all four conditions above are met. A weekend Uber gig, a rental flat, or a decent interest payout takes you out of the exemption.
  • Phishing SMS and email around tax season. SARS will never ask for your password, OTP, banking PIN or eFiling login through email, SMS, WhatsApp or a phone call, and it doesn't send links to other websites, including bank sites (SARS, Scams and Phishing). If a message promises a refund and asks you to click a link, don't. Log into eFiling directly instead.
  • Accepting your auto-assessment without checking it. SARS's pre-filled data comes from your employer, bank and medical scheme. If any of them made a mistake, it's now on your assessment too. Compare it with your own IRP5 and certificates before you let it stand.
  • Letting an unregistered "tax practitioner" submit for you. They can prepare a return, but only you (or a properly accredited practitioner) can hit submit.

Frequently asked questions

When does SARS eFiling open for the filing season?

Auto-assessments go out from 1 to 12 July 2026. Non-provisional individuals can file from 13 July to 23 October 2026, and provisional taxpayers and trusts have until 22 January 2027.

Do I have to submit a tax return if I earn under R500,000 a year?

Only if you meet all four conditions: one employer, no travel allowance or company car, no other income of any kind, and correct PAYE deductions all year. If you have a side hustle, rental income or investment interest, you need to file regardless of your salary.

What happens if I miss the SARS eFiling deadline?

You risk a penalty of R250 to R16,000 a month, based on your taxable income, for as long as the return stays outstanding, up to 35 months. Filing late before SARS catches it is still far cheaper than not filing at all.

How do I know if SARS auto-assessed me?

Check your eFiling dashboard or the SARS MobiApp between 1 and 12 July, or watch for an SMS or email from SARS. If you agree with the figures, you don't need to do anything; if you don't, file a full ITR12 by your deadline instead.

Can I file my SARS tax return using the MobiApp instead of eFiling?

Yes. The SARS MobiApp lets you register, view and submit your ITR12, and check your Notice of Assessment, just like eFiling on a computer. That helps if you're filing from your phone on mobile data.

How long should I keep my supporting documents after I file?

Five years. SARS doesn't want you to submit documents with your return, but it can ask for them later, and you need to be able to produce them.

If you earn extra from freelancing or a side hustle that now needs declaring, see our guides on starting freelancing in Africa without experience and the best freelance websites that pay. Both cover the kind of income that takes you out of the R500,000 exemption.
