Provisional taxpayers face D-Day as tax deadline has arrived

If you are one of South Africa’s provisional taxpayers, Monday is the day your tax bill stops being the tomorrow’s problem. The first payment for the 2027 tax year is due by 31 August. 

Miss it, and the South African Revenue Service (SARS) will not simply shrug and say, “See you next month.” There can be penalties, interest and a very unwelcome dent in your bank account.

This deadline matters because provisional tax is paid ahead of your final assessment. It helps spread your income tax bill across the year instead of producing one large bill later.

PROVISIONAL TAXPAYERS HAVE A DATE WITH SARS

Provisional taxpayers generally include people earning income outside remuneration, such as freelancers and self-employed workers. Companies also fall into the provisional tax system. Some people earning remuneration can qualify if their employer does not operate PAYE.

For the 2027 tax year, the first payment falls on 31 August. The second payment is due on 28 February 2027. A third payment can be made by 30 September 2027 if needed.

In other words, Monday is not a suggested date. It is the date.

MISS IT, AND SARS WILL NOTICE

For provisional taxpayers who miss the first payment, the consequences can start immediately. SARS can impose a 10% penalty on a late first or second provisional payment. Interest also applies to late or unpaid tax.

The current SARS interest rate for late or underpaid tax is 10.25% per year from March 2026. That means procrastination now has a price tag attached.

There is another trap for anyone who simply guesses their income. Underestimating taxable income can lead to an understatement penalty if the required thresholds are not met.

PROVISIONAL TAXPAYERS SHOULD CHECK THE NUMBERS

SARS expects an estimate based on taxable income, not a figure pulled from a hat. Taxpayers can use the SARS basic amount or calculate an estimate using current financial information.

For taxable income of R1 million or less, provisional payments generally need to meet the tax on the lower of the basic amount or 90% of actual taxable income. Above R1 million, the relevant threshold is 80% of actual taxable income.

That makes Monday about more than pressing the payment button. 

Provisional taxpayers should check their figures, submit the IRP6 and allow for banking clearance times. SARS says electronic payments can take two to five days to clear, so leaving it until Monday evening could be asking for trouble.

For anyone still staring at the calendar and hoping August somehow grew an extra day, it has not. 

Monday (today) is D-Day.
