📘 How to Use This UK Income Tax Calculator
This free UK Income Tax Calculator instantly computes your income tax, National Insurance, student loan repayments, and take-home pay for 2024–25 and 2025–26 — for both employed and self-employed individuals in England, Wales, Northern Ireland, and Scotland.
- Select your tax year. Choose 2024–25 (6 April 2024 to 5 April 2025) or 2025–26 (6 April 2025 to 5 April 2026). England, Wales and NI income tax bands are identical for both years as HMRC has frozen thresholds. Scottish bands and student loan thresholds differ by year.
- Choose your region. Scotland uses its own income tax rates set by the Scottish Parliament. For most incomes above £27,500, Scottish taxpayers pay more than in England, Wales, or Northern Ireland.
- Enter your gross annual income. Include all employment income before any deductions. For self-employed individuals, enter your net profit before tax.
- Enter tax already paid (PAYE). Find this on your payslips or P60. The calculator shows whether you’re due a refund or owe additional tax.
- Use Advanced Options for pension contributions (which reduce taxable income), student loan plans, Gift Aid donations, and the Blind Person’s Allowance.
UK Income Tax Bands 2025–26 Explained
The UK uses a progressive tax system: different portions of your income are taxed at different rates. Your personal allowance (£12,570) is completely tax-free. After that, the basic rate (20%) applies up to £50,270, then the higher rate (40%) up to £125,140, then the additional rate (45%) above that.
Example: £55,000 Salary (England, 2025–26)
Here is exactly how income tax is calculated on a £55,000 salary:
- £0 – £12,570: Personal allowance → £0 tax
- £12,571 – £50,270: £37,700 × 20% → £7,540
- £50,271 – £55,000: £4,730 × 40% → £1,892
- Total income tax: £9,432 — effective rate of 17.1%
- National Insurance: 8% on £37,700 = £3,016; 2% on £4,730 = £95 → £3,111 NI
- Take-home pay: £42,457/year (£3,538/month)
The £100,000 Income Tax Trap — The 60% Problem
This is one of the most punishing features of the UK tax system. When your income exceeds £100,000, your Personal Allowance is gradually withdrawn at £1 for every £2 earned above £100,000.
The result: on income between £100,000 and £125,140, you effectively pay 60% marginal tax — the 40% higher rate on the extra income, plus 20% on the allowance you lose.
How to Escape the 60% Trap
The most effective solution is to make pension contributions (via salary sacrifice or directly) to bring your adjusted net income below £100,000. Every £1 contributed to your pension reduces your adjusted net income by £1, restoring your personal allowance.
- Salary sacrifice pension — reduces gross income before NI and income tax, saving up to 60p in tax per £1 contributed between £100,000–£125,140
- Gift Aid donations — extend your basic rate band by the gross donation amount
- Venture Capital Trust (VCT) or EIS investments — can provide 30% upfront tax relief
Scotland vs England: Who Pays More?
Scotland has its own income tax rates set by the Scottish Parliament (for non-savings, non-dividend income only; savings and dividend income use UK rates). Thanks to the 19% starter rate, Scottish taxpayers at lower incomes actually pay slightly less than equivalent earners in England. The crossover point is approximately £27,500 — above this, Scotland becomes progressively more expensive.
| Annual Income | England Tax | Scotland Tax | Difference (2025‑26) |
|---|---|---|---|
| £20,000 | £1,486 | £1,458 | Scotland saves £28 |
| £30,000 | £3,486 | £3,483 | Approximately equal |
| £50,000 | £7,486 | £9,014 | Scotland pays £1,528 more |
| £80,000 | £19,432 | £21,764 | Scotland pays £2,332 more |
| £150,000 | £51,189 | £56,398 | Scotland pays £5,209 more |
Figures are income tax only, excluding National Insurance. Based on 2025‑26 rates with standard personal allowance (£12,570). At £150,000 the personal allowance is fully withdrawn for both regions.
National Insurance Explained
National Insurance (NI) is a separate tax from income tax, also collected by HMRC via payroll. For employees in 2025–26, the rate is 8% on earnings between £12,570 and £50,270, then 2% above £50,270. At a £35,000 salary, your NI is approximately £1,794/year. Note: your employer also pays 13.8% employer’s NI on your earnings above £5,000 (from April 2025 — the threshold was reduced from £9,100 to £5,000). This cost is not deducted from your pay but represents the total employment cost to your employer.
Self-Employed NI (Class 4)
If you are self-employed, you pay Class 4 NI at 6% on profits between £12,570 and £50,270, then 2% above £50,270. From April 2024, Class 2 NI (the flat weekly contribution) was abolished for most self-employed people.
Pension Contributions and Tax Relief
Pension contributions are one of the most tax-efficient ways to reduce your UK tax bill. You receive tax relief at your marginal rate on personal contributions:
- Basic rate taxpayer: 20% relief — contribute £80 and HMRC tops up to £100 in your pension
- Higher rate taxpayer: 40% total relief — a £100 gross pension contribution effectively costs you £60 (claim the extra 20% via self-assessment)
- Additional rate / 60% trap: Up to 60p relief per £1 contributed between £100,000–£125,140 via salary sacrifice
The annual allowance is £60,000 (2025–26) or 100% of earnings if lower. You can also carry forward unused allowance from the previous three tax years.
Tax Codes Explained
Your tax code tells your employer how much personal allowance you have. The most common code is 1257L — meaning £12,570 personal allowance. The letter L means you’re entitled to the standard allowance. Other common codes:
- BR — all income taxed at basic rate (20%), usually a second job
- 0T — no personal allowance (income above £125,140 or no P45/P46)
- W1/M1 — emergency tax code, taxed on a non-cumulative basis
- K codes — you have deductions exceeding your allowances (e.g. company car benefit)
- Scottish prefix S — Scottish taxpayer (e.g. S1257L)
If your tax code is wrong, contact HMRC or check via your Personal Tax Account.
Marriage Allowance and Blind Person’s Allowance
The Marriage Allowance lets one partner transfer £1,260 of their personal allowance to the other, saving up to £252/year in tax. The transferring partner must earn below £12,570 and the receiving partner must be a basic rate taxpayer. Apply via gov.uk/marriage-allowance.
The Blind Person’s Allowance is £3,070 for 2025–26, added on top of your personal allowance. You can claim it if you are registered as severely sight impaired with your local authority.
