How Is UK Tax Calculated?

A simple, visual guide to Income Tax, National Insurance and take-home pay for 2025/26.

📊 Income Tax Bands 2025/26

UK Income Tax is charged in progressive bands — you only pay the higher rate on earnings above each threshold, never on your whole income.

🛡️ National Insurance 2025/26

National Insurance (NI) contributions fund the NHS and State Pension. In 2025/26, the employee rate was cut to 8% on earnings between the Primary Threshold and Upper Earnings Limit.

Frequently Asked Questions
What is the Personal Allowance and how does it work?
The Personal Allowance (£12,570 for 2025/26) is the amount you can earn each year completely tax-free. It applies before any Income Tax is calculated. If you earn over £100,000, your allowance is reduced by £1 for every £2 above that threshold — disappearing entirely at £125,140.
What is a tax code and why does it matter?
Your tax code tells your employer or pension provider how much tax-free income you are entitled to. The most common code is 1257L, which gives you the standard £12,570 Personal Allowance. Emergency codes or codes ending in 0T mean you get no allowance and pay tax from the first pound. You can find your tax code on a payslip or by logging into HMRC online.
How does Salary Sacrifice affect my take-home pay?
Salary Sacrifice lets you swap part of your salary for a non-cash benefit (usually pension contributions). Because your gross salary is reduced, you pay less Income Tax and NI — making this one of the most tax-efficient ways to save for retirement. For example, a £40,000 earner putting 5% into a salary sacrifice pension saves roughly £300/year in NI alone compared to a standard pension deduction.
When do I need to repay a Student Loan?
You only repay once your income exceeds your plan's threshold. For 2025/26: Plan 1 — £26,065/year; Plan 2 — £28,470/year; Plan 4 (Scotland) — £32,745/year; Plan 5 — £25,000/year. You repay 9% of income above the threshold. Postgraduate loans have a 6% rate above £21,000.
What is the 60% tax trap?
If your income falls between £100,000 and £125,140, you lose £1 of Personal Allowance for every £2 earned above £100,000. Combined with the 40% Higher Rate tax, this creates an effective marginal rate of 60% on earnings in this range. Common solutions include making pension contributions to bring taxable income below £100,000.
How is the effective tax rate different from the marginal rate?
The marginal rate is the rate applied to your last pound of earnings (e.g. 40%). The effective rate is your total tax as a percentage of your gross salary — always lower because lower bands are taxed at lower rates. A £60,000 earner might have a 40% marginal rate but only a 24% effective rate, since most of their income is taxed at 20% or 0%.
