UK Money Guides
Practical guides to help you understand UK tax, salary, and personal finance. No jargon, no fluff — just clear explanations of how things actually work.
Understanding UK Tax
The UK tax system affects everyone differently depending on how you earn, how much you earn, and how your income is structured. Whether you are an employee, self-employed, a company director, or a property buyer, the rules are different — and understanding them can save you real money.
Our guides break down the most common areas of UK tax and finance into plain English. Each guide is paired with a calculator so you can see how the rules apply to your specific numbers.

Key UK Tax Concepts
Before diving into individual guides, here are the fundamentals that underpin most UK tax calculations:
- Personal allowance (£12,570): The amount you can earn before paying income tax. Tapers above £100k.
- Progressive tax bands: Only the portion of income within each band is taxed at that rate — not your entire income.
- National Insurance: A separate charge from income tax. Employees pay Class 1, self-employed pay Class 4.
- Tax year: Runs from 6 April to 5 April the following year. The current year is 2025/26.
- PAYE: Pay As You Earn — the system your employer uses to deduct tax before you receive your salary.
- Self Assessment: The system self-employed people use to report income and pay tax directly to HMRC.
