Provisional Tax: Don’t Forget the Third Top-Up – Penalties Still Apply

If you’re a provisional taxpayer in South Africa, meeting your first (August) and second (February) provisional tax deadlines is only part of the story. Many taxpayers overlook the third “top-up” payment, which can make a big difference when SARS assesses underestimation penalties.

What Is the Third Top-Up?

The third top-up is an optional payment made before the annual income tax return is assessed—usually by 30 September for individuals with February year-ends. It allows you to correct any underestimation of your taxable income made in the first two provisional payments.

Why It Matters

While the third payment is not mandatory, SARS will still charge underestimation penalties and interest if your first two payments fall short—even if you top up later. This is particularly relevant if your actual taxable income is significantly higher than initially projected.

When Is It Due?

For most provisional taxpayers with a 28/29 February year-end, the third top-up should be made by 30 September (seven months after year-end). Companies with different year-ends must calculate accordingly.

Avoid Penalties, Stay Compliant

The best strategy? Review your actual income and expenses after your financial year-end and assess whether a third top-up is necessary. Paying it on time can reduce or eliminate interest, but note that it won’t waive underestimation penalties.
