How we write our guides
Every guide on this site starts with the official source material: HMRC guidance, GOV.UK publications, Bank of England data, and Acts of Parliament where relevant. We then translate that into plain English that anyone can follow, without assuming a background in finance or accounting.
Rates, thresholds, and rules change regularly, especially in and around Budget statements each autumn. We review all guides after each Budget and update figures to reflect the current 2026/27 tax year.
Where something is genuinely complex or depends on your personal situation, like the interaction between pension contributions and your adjusted net income or non-dom tax rules, we say so clearly and point you to professional advice rather than oversimplifying.

Common questions about UK personal finance
- What is the personal allowance for 2026/27?
- The standard personal allowance (the amount you can earn before paying income tax) is £12,570 for 2026/27. This has been frozen since 2021/22 and is set to remain at this level until at least 2028. If you earn over £100,000, your personal allowance is reduced by £1 for every £2 you earn above that threshold, tapering to zero at £125,140.
- How much National Insurance do I pay as an employee?
- For 2026/27, employees pay 8% National Insurance on earnings between £12,570 and £50,270 per year, and 2% on any earnings above £50,270. Use our National Insurance calculator to see your exact NI bill at any salary.
- What is stamp duty and when do I pay it?
- Stamp Duty Land Tax (SDLT) is a tax on property purchases in England and Northern Ireland. You pay it when you buy a residential property over £125,000 (or £300,000 for first-time buyers buying under £500,000). Scotland has its own Land and Buildings Transaction Tax (LBTT), and Wales has Land Transaction Tax (LTT). Our Stamp Duty calculator works out how much you'll owe.
- How much can I put in an ISA each year?
- The ISA allowance for 2026/27 is £20,000. You can spread this across different ISA types: Cash ISA, Stocks and Shares ISA, Innovative Finance ISA, and Lifetime ISA (LISA, capped at £4,000 per year within the £20,000 allowance). Any interest, dividends, or growth within an ISA is completely tax-free, making them one of the most tax-efficient ways to save and invest.
- What is the current pension annual allowance?
- The pension annual allowance for 2026/27 is £60,000 (or 100% of your earnings, whichever is lower). This is the total amount you can contribute to all your pensions in a tax year while still receiving tax relief. Higher earners may face a tapered allowance if their threshold income exceeds £200,000 and adjusted income exceeds £260,000.
- Do these guides apply if I'm self-employed?
- Yes, many of the guides are relevant regardless of whether you're employed or self-employed. The Self-Assessment guide is specifically aimed at self-employed people, sole traders, and anyone with additional income who needs to file a tax return. Our Self-Employed Tax calculator covers Class 2 and Class 4 NICs alongside income tax.
