What provisional tax is, who must pay it, and how to calculate and submit it in South Africa. Deadlines and penalties explained.

Who Must Pay Provisional Tax

You are a provisional taxpayer if you earn income that does not have PAYE deducted — such as freelance income, business profits, rental income, or substantial investment income. Salaried employees with only one employer usually are not provisional taxpayers.

How to Calculate It

Estimate your total taxable income for the year, calculate the tax using the SARS brackets, then pay half at each provisional deadline. Our freelancer tax calculator does this for you.

Penalties to Avoid

Underestimating your income significantly, or paying late, results in penalties and interest. If your taxable income exceeds R1 million, your estimate must be at least 80% accurate to avoid an underestimation penalty.
