Methodology
These guides draw exclusively from authoritative UK government and statutory sources, primary legislation, HMRC publications, gov.uk reference pages, regulator data, and official statistics. Where worked examples appear, the arithmetic is derived from current statutory rates and rules, with the source-of-truth URL inline-cited at the relevant section.
Every guide is reviewed against its primary sources on update; the date stamp at the top of each guide marks the last review. Conflicts between our wording and the source documents are resolved in favour of the source, when in doubt, follow the citation.
