One address, read by a person, answered by a person.
That address reaches Neil McDonald, who writes and runs the site. There is no support desk and no ticket number — it is one inbox, and you will get a reply from the person responsible for the page you are writing about.
Corrections are the ones we most want. If a figure looks wrong, say which page and which number, and quote what you think it should be. Every calculation on this site has its formula and its primary source published on the methodology page, so a disagreement can usually be settled by pointing at the source.
The editorial policy sets out how the site is researched, how the writing is produced, and how it is funded.
We cannot tell you what you personally owe. Nothing on this site is tax advice or financial advice, we are not authorised to give either, and a page cannot know your circumstances — your other income, your losses, your residence, when you actually disposed of what. For that, an accountant is worth what they cost. HMRC's own guidance is in the Cryptoassets Manual, and it is more readable than its reputation suggests.
We also do not take paid placement, sponsored posts, guest articles or link requests. There is no price for coverage, so please do not ask for one.
Happy to explain any method on this site, and happy for the figures to be quoted with a link. If you want the derivation behind a specific number, ask — it is usually quicker to send it than to describe where to find it.
