Are You a Provisional Taxpayer? Here's What You Need to Know Before 31 August 2026

The first provisional tax return for the 2027 tax year (1 March 2026 – 28 February 2027) is due by 31 August 2026. Yet many taxpayers remain uncertain whether they are required to submit one at all.

According to Hobbs Sinclair Advisory, provisional tax obligations extend well beyond traditional business owners. "There is a persistent misconception that provisional tax only applies to companies or full-time entrepreneurs," says Morné Janse van Rensburg, Managing Director of Hobbs Sinclair Advisory. "In reality, it applies to anyone earning income other than remuneration subject to PAYE."

Importantly, earning a salary does not automatically exclude a taxpayer from provisional tax. If you earn additional income from a side-hustle, freelance work, rental property or a part-time business, you may still be classified as a provisional taxpayer — even though PAYE is deducted from your salary.

What Is Provisional Tax?

Provisional tax is not a separate tax. It is a system of advance payments towards your annual income tax liability.

For taxpayers with a 28 February 2027 year-end:

· First provisional payment: 31 August 2026

· Second provisional payment: 26 February 2027

These payments are based on an estimate of taxable income for the full tax year and are credited against the final assessment once the annual return is submitted.

Who Qualifies?

In terms of the Income Tax Act, a provisional taxpayer includes:

· Any natural person who derives income other than remuneration

· Any company

· Any person notified by the Commissioner that they are a provisional taxpayer

· Anyone earning remuneration from an employer not registered for PAYE

Most salary earners with no additional income streams are not provisional taxpayers.

Certain types of income also do not automatically trigger provisional status. For example:

· Interest below R23 800 (if under 65)

· Interest below R34 500 (if 65 or older)

· Exempt income from a tax-free savings account

Individuals earning below the applicable tax thresholds are also excluded:

· Under 65: R99 000

· 65 to under 75: R153 250

· 75 and over: R171 300

In addition, individuals whose taxable income from interest, foreign dividends, rental and certain types of remuneration does not exceed R30 000 may fall outside the provisional tax net.

Estimating Your Income

When submitting a provisional return, taxpayers may use either:

· The SARS "basic amount" – based on the latest assessed income tax return; or

· A calculated estimate – prepared using current financial information and reasonable assumptions.

"SARS expects a defensible estimate," says Janse van Rensburg. "If income has increased materially and that increase is not reflected, the taxpayer risks a penalty."

SARS may request supporting calculations where it believes the estimate is not appropriate.

Underestimation Penalties

After the annual return is assessed, SARS determines whether the second provisional estimate was reasonable. If provisional payments fall short, a 20% penalty may apply.

Where actual taxable income is:

R1 million or less

Total provisional payments must equal or exceed the tax payable on the smaller of:

· The SARS basic amount; or

· 90% of actual taxable income

More than R1 million

Total provisional payments must equal or exceed the tax payable on:

· 80% of actual taxable income

If these thresholds are not met, SARS levies a 20% penalty on the shortfall.

SARS may waive the penalty if the estimate was properly calculated and not negligently or deliberately understated. This decision is subject to objection and appeal.

Payment Consequences

The first provisional payment must reach SARS by 31 August 2026.

payment triggers:

· A 10% penalty on the outstanding amount; and

· Interest, currently 10.5% per annum, on the unpaid balance.

"The cost of missing the first provisional deadline can add up quickly," says Janse van Rensburg. "Taxpayers with fluctuating or additional income streams should review their position well before 31 August to ensure they are registered as provisional taxpayers, have estimated their taxable income correctly and submit their return on time."

Provisional tax is ultimately about ensuring income tax is paid progressively during the year. For taxpayers earning more than just a salary, confirming provisional status and submitting an accurate estimate before 31 August 2026 can prevent avoidable penalties and interest later in the tax year.
