UK Income Tax Rates & Brackets Guide (2025/2026)
Complete guide to UK income tax rates, tax bands, Personal Allowance, PAYE deductions, National Insurance, and salary take-home calculations.
The United Kingdom operates a progressive Income Tax system administered by HM Revenue & Customs (HMRC). Whether you are an employee paying tax through PAYE (Pay As You Earn), a sole trader filing a Self Assessment return, or a company director receiving dividends, understanding UK tax rates and thresholds is essential for managing your finances.
In this comprehensive guide, we cover current UK tax brackets (2025/2026 & 2026/2027), how the Personal Allowance works, how National Insurance contributions affect your salary, and how to calculate your net take-home pay.
1. UK Income Tax Rates and Bands (Rest of UK: England, Wales, Northern Ireland)
Income Tax is charged on your taxable income above your Personal Allowance. The standard UK tax year runs from 6 April to 5 April.
| Tax Band | Taxable Income Range | Income Tax Rate |
|---|---|---|
| Personal Allowance | Up to £12,570 | 0% |
| Basic Rate | £12,571 to £50,270 | 20% |
| Higher Rate | £50,271 to £125,140 | 40% |
| Additional Rate | Above £125,140 | 45% |
[!NOTE] Scotland Tax Rates: Scotland sets its own devolved income tax rates and bands for employment and self-employment income, featuring 6 tax bands ranging from 19% to 48%.
2. Understanding the Personal Allowance & £100,000 Taper
Every UK taxpayer is entitled to a standard Personal Allowance of £12,570 per tax year. This means your first £12,570 of earnings is completely free of Income Tax.
The £100k Personal Allowance Taper (60% Tax Trap)
When your Adjusted Net Income exceeds £100,000, your Personal Allowance is reduced by £1 for every £2 of income earned over £100,000.
- At £100,000, your Personal Allowance is £12,570.
- At £110,000, your Personal Allowance is reduced to £7,570.
- At £125,140, your Personal Allowance drops to £0.
Because you pay 40% tax on income over £100k and lose £1 of tax-free allowance for every £2 earned, your effective marginal tax rate between £100,000 and £125,140 is 60% (plus 2% National Insurance).
Marginal Tax Calculation between £100,000 and £125,140:
Income Tax on £1.00 earned: 40p
Loss of Allowance (50p taxed at 40%): 20p
National Insurance (2%): 2p
Total Tax & NI on £1.00 earned: 62p (62% marginal rate!)You can model the impact of the Personal Allowance taper using our free UK Income Tax Calculator.
3. Class 1 National Insurance Contributions (NI)
In addition to Income Tax, UK employees pay Class 1 National Insurance (NI) contributions, which fund state benefits and the UK State Pension.
- Primary Threshold (£12,570/yr or £242/wk): 8% NI on earnings between £12,570 and £50,270.
- Upper Earnings Limit (£50,270/yr or £967/wk): 2% NI on earnings above £50,270.
