A small, opinionated tax-tools shop.
We make calculators for the SARS rules that the bigger sites either don't cover or hide behind dated forms. We are not your tax advisor — we just want the maths to be honest.

Why this exists
A South African selling a flat in Sea Point, a parent helping a child with a deposit, a freelancer staring down their first IRP6 — these are everyday tax moments that deserve better than a 12-tab PDF or a calculator buried inside a bank's mortgage funnel.
Every calculator on this site does one thing well: returns a clear estimate, shows its working, and links you to SARS for the binding figure. Nothing more.
Run by Greg, an independent tax-curious operator based in South Africa. Editorial oversight by a registered tax practitioner — see the methodology page for sign-off details.
