About calculator·tax — free, private, worldwide tax calculator

What calculator·tax is

calculator·tax is a free, private, worldwide tax calculator and annual-return preparation tool. We cover 26 countries, each built natively — in its own language, currency, rates and legislation, with links to the official tax authority. It is not a translated copy of one calculator; every country is researched and built on its own rules.

Our mission

Tax is one of the most stressful and confusing parts of adult life — especially for people filing in a second language, freelancers, gig workers, investors and expats. Our goal is simple: make tax understandable for everyday people, in their own language, for free, and with complete privacy. No accounts, no data harvesting, no jargon walls.

How it works

Every calculation runs in your browser. Nothing you type is sent to a server or stored anywhere.
Rates come from official sources — HMRC, the IRS, the Bundeszentralamt für Steuern, the ANAF, the ATO, IRAS, SARS and each country's tax authority. See our methodology.
From calculation to filing. Where possible we go beyond a number and help you prepare your real annual return, mapped to the official boxes, for you to file yourself.
