Legal
Website terms of use
Last updated 7 November 2026.
These terms govern use of this website and the client portal operated by US UK Expat Tax. Tax services themselves are governed by the engagement letter you sign, which takes precedence.
Information, not advice
Content on this site, including calculators, is general information for people with US and UK tax obligations. It is not personal tax advice and you should not act on it without advice on your own facts. Figures are labelled with the tax year they relate to and may change.
Calculators
Calculators apply published rules to the figures you enter and state their assumptions. They do not store your inputs on our servers. Results are estimates for orientation only.
Client portal
Portal access is personal to the invited user. You must keep sign-in codes confidential and tell us promptly if you believe your email account has been compromised. Recording “Approve” against a document confirms you have reviewed that specific version; where a tax authority requires a separate signed authorisation, the portal will say so and that form governs. We log actions in the portal for security and record-keeping.
Acceptable use
You must not attempt to access other users' data, probe or disrupt the service, or upload unlawful or malicious content.
Liability
To the extent permitted by law we exclude liability for loss arising from reliance on website content. Nothing limits liability for fraud or for death or personal injury caused by negligence. Liability for tax services is set out in the engagement letter.
Intellectual property
Site content and design are ours or licensed to us. You may print or share pages for personal, non-commercial use with attribution.
