Terms of Use

Last updated: 27 October 2026

1. Estimates, not advice

The calculators and content on this site provide estimates based on published rules and the assumptions stated on each page. They are for general information only and do not constitute tax, legal, financial, accounting or immigration advice. Always confirm figures with the relevant authority, your employer, your lender or a qualified professional before acting on them.

2. Accuracy

We check rules against official sources and date each check, but rules change, authorities issue clarifications, and individual circumstances vary. We do not warrant that any result is accurate, complete or current for your situation.

3. Liability

To the fullest extent permitted by law, we accept no liability for any loss arising from reliance on a calculator result or any content on this site. Nothing in these terms limits liability that cannot be limited by law.

4. Acceptable use

You may use the calculators for personal and business purposes. You may not scrape the site at scale, reproduce the calculators or rules files commercially without permission, or interfere with the site's operation or advertising.

5. Intellectual property

The text, design, rules files and code of this site are our property or used under licence. Official rates and thresholds are public information; our compilation and presentation of them is not.

6. Changes

We may update these terms at any time; continued use after a change means you accept the new terms.
