Summary
This calculator computes the corporate income tax payable by a South African company for the 2024–25 tax year. SARS taxes company profits at a single flat rate of 27% — down from 28% effective 1 April 2023 — which applies to all taxable income regardless of amount. There are no progressive brackets for standard companies. The tool shows tax payable, after-tax profit, effective rate, and an indication of the two provisional tax installments companies are required to pay during the year.
