How UK salary tax is calculated in 2025/26
Your gross salary is reduced by three main deductions before it reaches your bank account: Income Tax, employee National Insurance contributions (NICs), and any pension contributions. Understanding how each one works helps you plan your finances and verify that your payslip is correct.
Income Tax is calculated on your taxable income — your gross salary minus the Personal Allowance (£12,570 for 2025/26). The basic rate of 20% applies to the first £37,700 of taxable income (up to £50,270 total). The higher rate of 40% applies between £50,271 and £125,140, and the additional rate of 45% applies above £125,140. Crucially, these are marginal rates — only the portion within each band is taxed at that rate, not your entire salary.
National Insurance is charged at 8% on earnings between £12,570 and £50,270 (the primary threshold to the upper earnings limit), and 2% above that. Unlike Income Tax, there is no personal allowance for NI — it kicks in from the first pound above the threshold.
Scottish income tax rates
If you live in Scotland, you pay Scottish income tax rates which differ significantly from the rest of the UK. Scotland has six tax bands compared to three in England, Wales, and Northern Ireland: Starter (19%), Basic (20%), Intermediate (21%), Higher (42%), Advanced (45%), and Top (48%). The thresholds also differ. This means a Scottish resident on the same gross salary as someone in England can have materially different take-home pay — sometimes higher, sometimes lower, depending on the salary level. This calculator handles both regions automatically when you select your location.
The personal allowance taper
If your adjusted net income exceeds £100,000, your Personal Allowance is reduced by £1 for every £2 of income above that threshold. This means it reaches zero at £125,140. The practical effect is a marginal tax rate of 60% on income between £100,000 and £125,140 — you lose £1 of allowance (which was saving you 40p in tax) for every £2 earned, on top of the 40% higher rate. Many higher earners use pension contributions to bring their adjusted net income below £100,000 and recover the full allowance.
Using this calculator for salary negotiation
When negotiating a salary, the number that matters is take-home pay — not the headline figure. A £5,000 pay rise from £45,000 to £50,000 adds approximately £3,250 to your annual take-home (after 20% tax and 8% NI). The same £5,000 rise from £50,000 to £55,000 adds only approximately £2,600 — because the portion above £50,270 is taxed at 40%. Understanding where you sit relative to the tax band boundaries helps you negotiate more effectively and evaluate whether a role change is financially worthwhile after deductions.
For contractors comparing day rates to permanent salaries, the Contractor Day Rate Calculator converts between the two, and the IR35 Calculator shows the take-home difference between inside and outside IR35 at any given rate.
