Why this guide exists

Tax decisions shouldn't be based on guesswork.

Most business owners make costly tax decisions not out of carelessness, but because the rules are buried in jargon and scattered across dozens of HMRC pages. This guide puts the numbers that matter in one place, in language that makes sense.

Written for people, not accountants

Every chapter is in plain English. Technical terms are explained the moment they appear.

Always current

The guide is hosted online. When HMRC updates rates, we update the guide. You always see the latest version.

Built around 2026/27 confirmed rates

Not a general explainer. Every figure, threshold, and deadline reflects the current tax year.
