How UK Income Tax is Calculated?

Your take-home pay is what's left after deductions. For most employees, this includes Income Tax and National Insurance. For the 2026/27 tax year, calculations use the latest confirmed thresholds.

Personal Allowance (£12,570)

The amount of income you can earn each year without paying any Income Tax. Frozen until 2028.

National Insurance (2026 Rates)

The main employee rate is 8% for earnings between £12,570 and £50,270, and 2% for anything above.

Tax Band Taxable 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 Over £125,140 45%
Note: Your Personal Allowance goes down by £1 for every £2 that your adjusted net income is above £100,000. This means your allowance is zero if your income is £125,140 or above.

How UK Income Tax Works

In the UK, most people have a Personal Allowance of £12,570, which is the amount of income you don't have to pay tax on. Anything above this is taxed at different rates depending on which 'tax band' your income falls into.

20% Basic Rate

On income between £12,571 and £50,270

40% Higher Rate

On income between £50,271 and £125,140

What is National Insurance?

National Insurance (NI) contributions qualify you for certain benefits and the State Pension. For the 2024/25 tax year, the main rate for employees is 8% on earnings between £12,570 and £50,270, and 2% on earnings above that.

Pro Tip: Reduce your Tax

Increasing your pension contributions via"Salary Sacrifice" reduces your taxable income, meaning you pay less Income Tax and National Insurance overall.

How this calculator works

The calculator estimates UK Income Tax by applying the Personal Allowance, then taxing slices of income across the basic, higher and additional rate bands. It also estimates employee National Insurance and optional student loan deductions to show a broader picture of take-home pay.

Assumptions used

  • The figures are based on the selected UK tax year and the assumptions shown on this page.
  • Personal Allowance tapering is estimated for higher incomes where applicable.
  • The tool is intended for common employee-style scenarios and does not model every payroll adjustment or benefit interaction.
  • Scottish income tax rates are not separately modelled unless explicitly stated on the page.

Frequently asked questions

Why does the tax rate increase as income rises?

Because UK Income Tax is progressive. Different portions of your income are taxed at different rates rather than the whole salary being taxed at the top band.

What happens above £100,000?

Your Personal Allowance is reduced by £1 for every £2 of adjusted net income above £100,000, which increases your effective marginal tax rate.

Why is my payslip different?

Real payroll may include benefits, bonus timing, pay frequency rules, student loan rounding or pension scheme differences that are outside a simplified online estimate.

Who should verify the final number?

Use HMRC guidance, your payroll provider, or a qualified accountant if you need exact figures for tax filing, employment negotiations or formal financial decisions.
