The UK tax year runs from 6 April 2025 to 5 April 2026. If you’ve ever looked at your payslip and thought, “Hang on… where’s all my money gone?”, you’re not alone. Between Income Tax and National Insurance, it’s easy to underestimate what you’ll actually take home — especially once you cross a band threshold.

Why people get caught out by tax bands
A common misunderstanding is thinking that if you go into a higher tax band, all your income gets taxed at the higher rate. That’s not how it works.
In the UK, Income Tax is calculated in bands. You only pay the higher rate on the portion of your income above that threshold — not on everything you earn. That said, a pay rise can still feel smaller than expected once tax and NI are taken into account, which is why it’s handy to check the numbers first.
Personal Allowance: the tax-free part (and why it matters)
Most people get a Personal Allowance — the portion of income that can be earned before Income Tax applies. This is one of the biggest reasons your “overall” percentage isn’t the same as the headline tax rate (like 20% or 40%).
But your Personal Allowance can change depending on your circumstances — for example, it can reduce if your income is high, and some tax codes reflect deductions or benefits.

Don’t forget National Insurance
Income Tax is only part of the picture. Many people feel surprised by deductions because National Insurance is also taken from earnings (depending on your employment status and income level). When you combine Income Tax and NI, your take-home pay can be noticeably lower than expected.
That’s why an all-in view matters. A quick estimate helps you plan your monthly budget properly, especially if you’re:
- moving jobs or changing salary
- switching from part-time to full-time
- taking on overtime
- setting a realistic savings target
Planning tip: think in “effective percentage”
If you’re self-employed, or you simply like to keep money aside as you go, a helpful approach is to think in terms of an effective percentage — the overall portion of income that goes on deductions, not just the headline tax band.
Once you know your rough effective percentage, you can save that amount automatically each time you get paid. It makes tax and bills feel a lot more predictable.
