Frequently asked questions
Is any of the data I enter stored?
No. Every calculator runs entirely in your browser using JavaScript. Nothing is sent to a server, nothing is logged, and nothing persists after you close the tab — apart from the values in the page address if you copy the link yourself.
Can I share a calculation with someone?
Yes. The inputs are kept in the page address, so the Copy link button gives you a URL that reopens the calculator with the same numbers. Copy result puts a plain-text summary on your clipboard instead.
How often are the tax rates updated?
After every Budget and whenever a rate notification changes something material. All statutory figures sit in one place in the code, which is what makes that straightforward.
Can I print a calculation?
Yes. The Print button produces a clean page with the inputs, the result and any schedule, and without the navigation, footer or buttons.
Do the calculators work on a phone?
Yes. The forms, charts and schedule tables all reflow for small screens, and the number fields open a numeric keypad.
