How income tax works for London employees
For most people in London, income tax is calculated using the same UK-wide PAYE rules that apply across England, Wales, and Northern Ireland. London does not have separate local income tax bands.
Income tax bands (England rates)
| Band | Taxable income | 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% |
Personal allowance taper for high earners
If adjusted income rises above £100,000, your personal allowance is reduced by £1 for every £2 earned over that level. It reaches zero at £125,140. This creates a high effective marginal tax zone, so planning pension contributions can become very valuable.
What else is deducted from pay
National Insurance (employee)
- 8% on earnings between £12,570 and £50,270.
- 2% on earnings above £50,270.
Student loan deductions
Student loan repayments are based on your plan and income threshold. If your income exceeds the threshold, a percentage is deducted from the excess only. This calculator includes common plans for quick estimation.

Ways to reduce your tax bill legally
1) Increase pension contributions
Because pension contributions can reduce taxable income, they may lower income tax and National Insurance while building long-term retirement savings.
2) Use ISA allowances for investing
ISAs do not reduce employment income tax directly, but they can shelter investment growth and income from further tax.
3) Check your tax code regularly
An incorrect tax code can lead to overpayment or underpayment. Correcting it early helps avoid surprises later in the tax year.

FAQ
Does London have different income tax rates?
No. London uses the same income tax system as the rest of England for employment income.
Why does my take-home seem lower than expected?
After income tax, National Insurance, pension deductions, and possible student loan repayments, net pay can be much lower than gross salary.
Can this replace payroll software?
No. It is best used for planning and budgeting. Payroll systems use exact period-based calculations and tax code details.
