Tax, explained without the jargon

UK tax has a reputation for being complicated, and the official guidance isn't always easy to follow. Our guides aim to fix that. Each one takes a single topic — how income tax bands work, what you can claim as a self-employed person, how stamp duty is calculated — and explains it in plain English, with worked examples and links to the calculators that do the maths for you.

The guides are written and reviewed by the TaxFly editorial team and updated when the rules change, so you're reading about the system as it works now, not several years ago. Wherever a guide mentions a figure you can apply to your own situation, you'll find a matching tool: pair our take-home pay guidance with the Take-Home Pay Calculator, or read up on dividends and then try the Dividend Tax Calculator.

Where to start

If you're employed, begin with the basics of income tax and National Insurance. If you work for yourself, the self-employment and Self Assessment guides will save you the most time. Buying or selling property? Start with stamp duty and capital gains. And if you just want the numbers, head straight to our full library of free UK calculators. Everything here is free to read, with no account required.

TaxFly guides are general information, not personal financial or tax advice. For decisions about your own circumstances, speak to a qualified accountant or adviser.

Official & accurate

Every figure follows HMRC 2026/27 rates and links to its gov.uk source.
