How Do UK Tax Codes Affect Your Take-Home Pay?
Your tax code instructs your employer how much income to allocate tax-free across pay periods. The standard code for 2026/27 is 1257L, representing the £12,570 allowance; custom suffixes or emergency codes (such as W1, M1, or BR) adjust this deduction schedule.

What is the 60% Marginal Tax Trap and How Does It Work?
Between £100,000 and £125,140, the withdrawal of the £12,570 Personal Allowance introduces an effective 60% marginal tax rate. For every £100 earned in this band, you lose £50 of allowance (taxed at 40% = £20) plus standard 40% income tax (£40), totaling £60 in tax per £100 earned.

Step-by-Step Worked Calculations for 2026/27
The worked examples below illustrate how HMRC tax bands, National Insurance (8% / 2%), and standard 5% auto-enrolment workplace pensions interact across typical salary points.
£25,000 Salary (Basic Earner)
All taxable income (£12,430) is within the 20% basic band. Monthly take-home is approximately £1,689.13.
£50,000 Salary (Higher Threshold)
Taxable income remains under the £50,270 higher rate threshold. Monthly take-home is approximately £3,084.97.
£100,000 Salary (Pre-Taper)
Basic tax: £7,540; Higher rate tax: £19,892. Monthly take-home is approximately £5,296.45 before taper kicks in.
£110,000 Salary (60% Tax Trap)
Math: £10k excess over £100k reduces Personal Allowance by £5,000. You pay £4,000 tax on the £10k plus £2,000 extra tax on the lost allowance = £6,000 total tax (60% effective marginal rate).
