As we move through tax season, provisional tax remains one of the most important compliance areas for both companies and individuals earning income outside of standard employment.

Provisional tax is not a separate tax. It is a system that allows SARS to collect income tax in advance, based on an estimate of your taxable income for the year. For companies, it is mandatory. For many individuals, it applies as soon as income is earned outside of PAYE structures.

Below is a clear overview of who it affects, the key deadlines, how the calculation works, and the risks of getting it wrong.

Who Must Pay Provisional Tax?

Companies

All companies registered in South Africa are provisional taxpayers by default, regardless of size or turnover. Even if the company is not actively trading, provisional tax returns may still be required.

Individuals

You are considered a provisional taxpayer if you earn income not subject to PAYE, including:

• Business or freelance income
• Rental income
• Investment income above SARS thresholds
• Income from an employer not registered for PAYE
• Foreign income not fully taxed through PAYE

Many business owners, consultants, landlords and investors fall into this category.

Who Is Generally Excluded?

For individuals, provisional tax does not apply if:

• You do not run a business and your taxable income is below the SARS tax threshold
• Your total passive income (interest, dividends and rental) is R30 000 or less for the year
• You fall into specific excluded categories such as certain PBOs, recreational clubs, body corporates or deceased estates

Key Provisional Tax Deadlines

Provisional tax is paid in two compulsory instalments each tax year, with an optional third payment available.

First Provisional Payment

• Due: 31 August
• Payment: 50% of the estimated total annual tax liability

Second Provisional Payment

• Due: 28 February
• Payment: The remaining balance of the estimated annual tax

The February deadline is critical for both companies and individuals. An incorrect estimate or late payment can result in immediate penalties and interest.

Optional Third Payment (Top-Up)

• Due: 30 September after the tax year-end
• Purpose: To reduce or eliminate interest where earlier estimates were too low

How Provisional Tax Is Calculated

Provisional tax is submitted via the IRP6 form on SARS E-fling and is based on estimated taxable income.

The process is straightforward in principle:

1. Estimate total taxable income for the full tax year.
2. Calculate the tax payable on that amount.
3. Subtract PAYE and any allowable credits already paid.
4. The balance is the provisional tax due.

For companies, this requires realistic forecasting of profits. For individuals, it requires careful consideration of business income, rental income, investment returns and any once-off receipts.

Underestimating income to reduce cash flow pressure can be costly.

Penalties and Interest

SARS enforces provisional tax compliance strictly.

Late Payment Penalty

A 10% penalty applies to any unpaid amount after the due date.

Interest

Interest accrues daily on outstanding amounts.

Underestimation Penalty

If the second provisional tax estimate is significantly lower than the final assessed taxable income, SARS may impose an underestimation penalty. This is particularly relevant for companies and high-income individuals.
