UK Salary & Take-Home Pay Calculator (2025/2026)

If your adjusted net income exceeds £100,000 in a tax year, your £12,570 Personal Allowance is reduced by £1 for every £2 of income above £100,000. Once your income reaches £125,140, your Personal Allowance is completely zeroed out. This creates what tax advisers call the '60% tax trap': for every £100 earned between £100,000 and £125,140, you pay £40 in income tax plus £20 because of the £50 lost allowance taxed at 40%, plus 2% National Insurance — giving an effective marginal rate of 62%. Contributing to a pension or making charitable gift-aid donations can restore your personal allowance by lowering your adjusted net income below £100,000.

Income Tax and National Insurance are two separate statutory deductions collected by HMRC. Income Tax is a cumulative annual tax that funds general government spending, with bands at 20%, 40%, and 45%. National Insurance Contributions (NICs) fund specific state benefits, including the UK State Pension, statutory maternity pay, and jobseeker's allowance. Employees pay 8% on weekly earnings between £242 and £967 (£12,570 to £50,270/yr) and 2% on earnings above £967/week (£50,270/yr). While income tax accounts for pension contributions and personal tax credits, NI is assessed on cash earnings per pay period.

Pension contributions benefit from full income tax relief at your highest marginal rate. If you are a basic rate (20%) taxpayer, a £100 pension contribution only costs you £80 in take-home pay because the government adds £20. If you are a higher rate (40%) taxpayer, that same £100 contribution only costs you £60, and for additional rate (45%) taxpayers, it costs £55. Under a 'Salary Sacrifice' scheme, you also save the 8% or 2% National Insurance on the sacrificed salary, maximizing take-home efficiency.

Student loan repayments are automatically deducted by your employer through PAYE once your annual earnings exceed the threshold for your plan: Plan 1: 9% over £24,990; Plan 2 (post-2012 undergraduate loans in England/Wales): 9% over £27,295; Plan 4 (Scotland): 9% over £31,395; Plan 5 (new loans starting August 2023): 9% over £25,000; Postgraduate Loan: 6% over £21,000. Deductions only apply to earnings above the threshold, not your total gross pay.

No. The Scottish Parliament sets its own Scottish Income Tax (SIT) rates and bands for earned income, which currently includes Starter (19%), Basic (20%), Intermediate (21%), Higher (42%), Advanced (45%), and Top (48%) rates. However, National Insurance rates and the Personal Allowance (£12,570) remain UK-wide under Westminster jurisdiction. This calculator displays the England, Wales, and Northern Ireland HMRC tax schedules.

1257L is the standard tax code indicating you are entitled to the full £12,570 tax-free personal allowance. If your payslip shows a different code (such as BR, 0T, K-codes, or W1/M1 emergency codes), you may be paying too much or too little tax. For instance, BR taxes all income at 20% with zero allowance (common on second jobs), while K-codes indicate taxable benefits (like company cars or medical cover) exceed your personal allowance. You can check and adjust your tax code directly through your HMRC Personal Tax Account online or via the HMRC app.
