About CheckMyTax
Free, plain-English tax tools.
What we do
We build quick tools for tax questions that government forms make hard. The tax code picker follows IRD's IR330 rules and is tested against every income band.
Disclaimer
Everything here is general information, not tax or financial advice. Rules change, so check with Inland Revenue (IRD) or a tax agent before you act.
Privacy
The tools run entirely in your browser. What you type is not sent to us or stored anywhere.
We count visits with Cloudflare Web Analytics, which doesn't use cookies, doesn't track you across other sites, and never sees what you type into a calculator.
