1. Who you are dealing with
The site is published by Opsigamytensor, 9 Beechwood Rd, Haddington EH41 3AW, United Kingdom. Contact [email protected] or +44 7911 863491. These terms govern use of the public pages. They are not a letter of engagement for tax, legal or investment services.
2. Information, not advice
The notes are general information about UK cryptoasset tax considerations, written for a wide readership. They are not advice on your facts, not a recommendation to buy, sell or hold any asset, and not a computation you can file. Tax outcomes depend on the full history of a pool, on other income, and on rules that change. You remain responsible for your own return and for checking current GOV.UK material, including the Cryptoassets Manual, or for instructing a qualified adviser.
3. No client relationship
Reading a page, using the illustration calculator, or sending an email does not create a client relationship, a duty of care to prepare your return, or an obligation to reply. If we reply, the reply is still general correspondence about the published material unless we expressly agree otherwise in writing. We do not agree otherwise by silence.
4. Figures and currency of the notes
Rates, allowances and deadlines are described for a named tax year, principally 2026/27, and are believed to reflect the published structure at the date on the page. They can be superseded by legislation, by an HMRC update, or by a correction we have not yet made. The illustration calculator applies only the operations described beside it. It ignores losses, matching rules, income and the personal-allowance taper.
5. Acceptable use
Do not misuse the site. In particular, do not attempt to break the host, scrape the pages in a way that degrades the service, send malware, or send us seed phrases, private keys or other people’s personal data. You may quote a short extract with a link to the page, for commentary. You may not present the notes as your own publication or as an official HMRC text.
6. Intellectual property
The text, the layout and the original photographs are owned by Opsigamytensor or used with permission. You may share a link freely. You may print a page for your own reading. Any wider reuse needs written consent from [email protected], except where copyright law already allows it.
7. Third-party links
Links to GOV.UK and to map or font hosts are provided for convenience. Those sites have their own terms. A link is not an endorsement of any product mentioned nearby, and GOV.UK remains the official text where we differ.
8. Liability
To the extent the law allows, Opsigamytensor excludes liability for loss arising from reliance on the notes, the calculator, or a delay in updating a page. We do not exclude liability for death or personal injury caused by negligence, or for fraud, or for any other liability that cannot legally be excluded. Nothing in these terms affects your statutory rights as a consumer.
Because the notes are general, you should not rely on them as the sole basis for a disposal, a disclosure, or a payment to HMRC. The loss that follows from doing so is a loss these terms warn you about.
9. Privacy
The privacy policy explains what happens to correspondence and to the consent value stored on your device.
10. Law and courts
These terms are governed by the law of Scotland. The courts of Scotland have jurisdiction. If you live in another part of the United Kingdom you may also have the right to bring a claim in your local courts where consumer law gives you that right.
11. Changes
We may update these terms by publishing a new version on this page and changing the date. The version you are reading is the version that applies to your use after that date. The notes themselves may be updated more often than the terms.
