How to Use the UK Salary Calculator
The UK Salary Calculator computes your exact take-home pay for 2026/27, accounting for Income Tax (at 20%, 40%, and 45% bands), National Insurance (Class 1 employee contributions), pension contributions, and student loan repayments. It handles all thresholds and tapers accurately.
Enter your annual gross salary, select your tax code (if known), pension contribution percentage, and student loan plan. The calculator instantly shows your monthly and weekly take-home, tax breakdown, NI contributions, and effective tax rate.
A crucial nuance is the Personal Allowance taper: for incomes above £100,000, the £12,570 personal allowance reduces by £1 for every £2 earned over £100,000, effectively creating a 60% marginal tax rate between £100,000 and £125,140. Above £125,140 the personal allowance is fully withdrawn. Pension contributions can restore the personal allowance.

Frequently Asked Questions
What is the UK personal allowance for 2026/27?
The personal allowance is £12,570 — the amount you can earn before paying income tax. It's been frozen at this level since 2021/22 and is set to remain until 2027/28. For incomes over £100,000, the allowance reduces by £1 for every £2 above the threshold.
What are the UK income tax bands for 2026/27?
In England, Wales, and Northern Ireland: 20% Basic Rate (£12,571–£50,270), 40% Higher Rate (£50,271–£125,140), 45% Additional Rate (above £125,140). Scotland has different rates: 19% Starter Rate, 20% Basic, 21% Intermediate, 42% Higher, 45% Advanced, 48% Top Rate.
How is National Insurance calculated in 2026/27?
Employee Class 1 NI: 8% on earnings between £12,570 and £50,270, and 2% on earnings above £50,270. The 2% rate was reduced from 12% to 8% in April 2024. Employer NI is separate: 15% on earnings above £5,000 per employee (threshold reduced from £9,100 in April 2025).
When do I start paying higher-rate tax?
Higher-rate income tax at 40% kicks in on earnings above £50,270 in England (2026/27). However, if your employer deducts pension contributions before tax, your taxable income is lower. A £55,000 salary with a 5% pension reduces taxable income to £52,250, meaning you pay 40% only on £1,980 above the threshold.
How does Gift Aid affect my tax bill?
Gift Aid allows charities to claim 25p from HMRC for every £1 you donate. Higher-rate taxpayers can also claim back the 20% difference between basic and higher-rate tax through their self-assessment return. A £100 donation becomes a £125 donation to the charity, and costs you only £75 as a higher-rate taxpayer.
