Editorial policy

Last updated: October 7, 2026

This page explains how we research, check, update and correct our guides, so you can judge how much to rely on them.

1. Sources

We use primary sources for every rule and figure we publish. In practice that means:

  • Tax: the Internal Revenue Service (IRS) in the US, HM Revenue & Customs (HMRC) and GOV.UK in the UK, and the Canada Revenue Agency (CRA) in Canada.
  • Regulation: the Securities and Exchange Commission (SEC), the Commodity Futures Trading Commission (CFTC), FinCEN and state regulators in the US; the Financial Conduct Authority (FCA) in the UK; the Canadian Securities Administrators (CSA) and FINTRAC in Canada.
  • Fraud data: the FBI's Internet Crime Complaint Center (IC3), the Federal Trade Commission (FTC), the UK's Report Fraud service and the Canadian Anti-Fraud Centre.

Every guide lists its sources at the end with direct links. When we describe how something works in general (for example, how an order book matches trades), we stick to widely documented facts and avoid predictions.

2. Checking

  • Every figure (rates, thresholds, allowances, deadlines, statistics) is copied from the source, not from memory or from other websites.
  • Worked examples are calculated step by step and checked again before publishing.
  • Each guide shows the date its figures were last checked against the sources.
  • If the official guidance is ambiguous, or we can't confirm a figure from a primary source, we leave it out or say clearly that it is uncertain.

3. Updates

Tax figures change with each tax year and regulators update their rules. We review our tax guides when new figures are published (for example, the IRS inflation adjustments each autumn, the UK Budget and the start of the UK tax year on 6 April) and our regulatory guides when the rules change. The "Updated" date on a guide changes only when its content changes.

4. Corrections

If you think something is wrong, contact us with the page and, if you can, the source that contradicts it. We check every report. When we correct a material error, we update the page and its dates.

5. Independence and advertising

  • The site is funded by Google advertising. Ads are chosen by Google's systems, are labelled as ads, and have no influence on what we write.
  • We don't use affiliate links, sponsored posts or paid placements, and we don't accept payment from exchanges, wallets, brokers or apps.
  • We never tell you to buy, sell or hold a particular crypto asset.

6. Not advice

Our guides are general information. They are not financial, investment, tax or legal advice, and they can't take your circumstances into account. Crypto assets are high-risk and, in most cases, not covered by deposit insurance or compensation schemes.
