Do you need to submit a tax return in South Africa?

The single most common tax question we hear, followed by three close relatives: when is the deadline, what is provisional tax, and what happens if I filed late? Here are the straight answers.

Last reviewed: 22 August 2026

1. Who must submit an ITR12?

You are required to submit an individual income tax return (ITR12) if any of the following apply to you for the year of assessment:

• Your total employment income for the year exceeded the annual filing threshold announced by SARS (this threshold adjusts most years, so confirm the current figure rather than relying on an old one).
• You had more than one employer during the year, or worked part of the year for an employer.
• You received income beyond a salary: rental income, investment income above the exempt threshold, business or freelance income, or capital gains.
• You carry on any trade in South Africa, other than solely employment.
• You want to claim a deduction (for example medical expenses above the credit, retirement annuity contributions, or travel allowance claims) that requires a return to be filed.
• SARS has asked you to submit, even if none of the above apply.

If your only income was a salary from one employer for the full year, below the annual threshold, with no additional income or deductions, you may not need to file at all. Many taxpayers who should not be filing keep receiving filing demands because their status was never corrected with SARS. That is fixable, but only deliberately.

2. When are the deadlines?

SARS announces exact opening and closing dates each year, and they shift slightly. As a rule of thumb:

• Individuals (non-provisional): the filing season usually opens in July and closes around late October for online submissions.
• Provisional taxpayers: individual returns typically run later, into mid-January of the following year.
• Companies: within 12 months of financial year-end, driven by your own year-end date.

Treat published deadlines as fixed. Every year we see penalties that exist purely because someone assumed last year's dates applied.

3. What is provisional tax, and do I owe it?

If you earn income on which no employer deducts PAYE (rental properties, investment returns, freelance or business income), you are likely a provisional taxpayer. Provisional tax spreads your liability across the year through two declarations:

• First period (IRP6): roughly half-way through your tax year.
• Second period (IRP6): at the end of your tax year, where estimates must be calculated carefully; deliberate under-estimation attracts penalties.
• A third "top-up" payment may follow the assessment where the estimate rules were missed.

Provisional tax is where self-employed people get hurt most often: no one reminds them, the second-period estimate is guessed, and the underestimation penalty arrives long after the fact. Planned properly, it never surprises you.

4. What happens if I submitted late, or never submitted?

Consequences stack quietly:

• Administrative penalties for outstanding personal returns run monthly, scaled by your income bracket, and continue until the return is filed.
• Interest accrues on unpaid assessments.
• Compliance status drops, which blocks tax clearance certificates needed for tenders, visas and lending.
• Where returns were never submitted, SARS can eventually issue estimated assessments based on its own assumptions, which are rarely generous.

The remedy is always the same sequence: file what is outstanding, verify the numbers behind it, then request remission of penalties where reasonable grounds exist. Penalty remission requests succeed or fail on how well the grounds are documented.
