Editorial Standards

Editorial ownership

Content is written and reviewed by James Whitfield, UKCapitalGainsTaxCalculator's editorial owner. James has a background in UK capital gains tax, the annual exempt amount and asset disposal reporting for shares, property and other investments. All calculator pages and guides are checked against current HMRC guidance before publication.

For corrections or factual feedback, contact James via the contact page or at contact page.

Accuracy and sourcing

• Rates, thresholds and legislative references are checked against official HMRC and GOV.UK sources.
• Guides and calculators are reviewed and updated when tax-year assumptions change.
• We prioritise factual accuracy and plain British English over marketing language.
• We do not provide personal financial or legal advice.
• Every page should be useful without requiring JavaScript for core explanatory content.

How we research and write content

• Content is written in plain British English and reviewed for practical readability by a UK taxpayer audience.
• Calculator assumptions and written guide explanations are reviewed together so tool logic and editorial content remain consistent.
• We prefer worked examples, rate comparisons and actionable guidance over generic definitions.
• We update titles, assumptions and internal links when tax-year rules change or when a page's stated purpose becomes inaccurate.
• Sources used are linked and listed on the sources page. Methodology details are on the methodology page.

Commercial relationships and editorial independence

Some pages on this site may include links to third-party tools or services — for example, tax advisory or investment platforms. Where those links are affiliate links, they are disclosed clearly on the relevant page. We may receive a commission if a reader purchases through an affiliate link, at no extra cost to them.

• Commercial relationships do not influence the factual content of our guides or calculator logic.
• Product descriptions are factual summaries based on publicly available information — they are not endorsements.
• We do not accept payment in exchange for editorial coverage or favourable placement.
• Readers should always check provider pricing, features and terms directly before making a decision.

Corrections and feedback

If you find a factual error in a guide, a calculation assumption that appears incorrect, or content that does not reflect the current tax year, please contact us via the contact page. We review all substantive correction requests and update pages where appropriate.
