About Mzansify

Mzansify provides free, accurate tax calculators for South African taxpayers. Our tools help you estimate your income tax, transfer duty, capital gains tax, medical credits, retirement contributions, and small business tax.

All calculations run entirely in your browser. We do not collect, store, or transmit any personal or financial information. Your data never leaves your device.

Our calculators are updated annually when SARS publishes new tax rates, typically following the National Treasury Budget Speech in February.
