Provisional Tax in South Africa Explained Simply

If you earn freelance, rental, or investment income, you're likely a provisional taxpayer. Here's what that means and how to handle it.

Published 15 April 2025

Who Is a Provisional Taxpayer?

You must register if you earn any income not subject to PAYE (employees' tax). This includes: freelance or contract income (even R1), rental income from property, interest income exceeding R23,800 (under 65) or R34,500 (65+), directors' fees not on PAYE, and any trade income. Salaried employees whose ONLY income is salary and interest below the exemption are NOT provisional taxpayers. If you're unsure, register — there's no penalty for being registered and submitting IRP6s with zero income.

How to Calculate Your Provisional Tax Payment

Estimate your total taxable income for the full year. Apply the income tax tables to get the total tax liability. Subtract any PAYE already deducted by employers. Subtract medical tax credits. Divide the remainder by 2 for each IRP6 payment. Tip: use the previous year's assessed income as a starting point, adjusted for any changes. SARS provides a worksheet on eFiling to help with the calculation.

Deadlines and Penalties

First IRP6: 31 August (6 months into the tax year). Second IRP6: 28/29 February (end of tax year). Third voluntary top-up: 30 September (for the previous tax year). Underestimation penalty: 10% of the difference if your estimate is less than 80% of your actual taxable income (90% if income exceeds R1 million). Interest charged on late payments at the current prescribed rate (~11.5% per annum). It's always better to slightly overestimate — you'll get the excess back as a refund.

Tips for Managing Provisional Tax

Set aside 25-35% of every freelance payment received for tax. Open a dedicated tax savings account. Upload your bank statements to TIT Tax monthly to track your taxable income in real-time. Review your estimate before each IRP6 deadline and adjust. If your income changes significantly mid-year, update your estimate on the second IRP6 — it's an opportunity to correct your first estimate.
