Terms of Use

Last updated August 2026

By using TaxFly (the "site"), you agree to these terms. If you do not agree, please do not use the site.

Estimates, not advice

Our calculators and guides provide general information and estimates for the UK tax system. They are not personal financial, tax or legal advice. Always confirm important figures with a qualified professional or GOV.UK. See our full disclaimer.

Accuracy

We work hard to keep figures accurate and up to date (see how we calculate), but we cannot guarantee the site is error-free or current at all times, and we accept no liability for decisions made based on it.

Free accounts

You can use the site without an account. If you create a free account, you are responsible for keeping your login details secure and for the activity under your account. Accounts are for your own personal use. We may suspend or remove accounts that are misused, and you can delete your account and all of its data at any time from your privacy and data settings.

Saved data and documents

If you save results or upload documents (such as HMRC letters, invoices or receipts), you are responsible for the content you upload and for keeping your own copies of anything important. We store your saved data securely as described in our privacy policy, but we are not a record-keeping or backup service, and you should not rely on us as your only copy.

Document reading and third-party data

Tools that read documents (the HMRC letter reader and receipt scanner) and tools that show official data (such as Companies House filing dates or the Bank of England base rate) are provided for convenience. The results are automated estimates and summaries, not advice, and may be incomplete or out of date. Always check the original letter, your records, and the official source before acting.

Acceptable use

You may use the site for personal, lawful purposes. You must not attempt to disrupt the site, scrape it at scale, upload unlawful or malicious files, or republish its content without permission.

Intellectual property

All content on this site is owned by TaxFly unless stated otherwise. You may share links freely.

Changes

We may update these terms at any time. Continued use of the site means you accept the current version.

Official & accurate

Every figure follows HMRC 2026/27 rates and links to its gov.uk source.

Private & secure

Calculations run in your browser. Your figures are never stored or shared.

Free for everyone

No account, no paywall, no limits. All our tools are completely free.
