## Comparing Two UK Salaries Side by Side

When considering a new job offer, a pay rise or comparing your salary with a partner or colleague, looking at gross figures alone is misleading. A £5,000 pay increase doesn't mean £5,000 more in your pocket — the actual difference depends on which tax bands the extra income falls into.

### Why Net Pay Differences Aren't Linear

UK income tax is progressive, meaning different portions of your income are taxed at different rates. Moving from £45,000 to £50,000 adds £5,000 gross but only around £3,600 net (after 20% tax and 8% NI). Moving from £50,000 to £55,000 adds the same gross amount but only around £2,900 net because the higher rate (40%) kicks in at £50,270.

### The £100,000 Trap

Earning between £100,000 and £125,140 is particularly expensive due to the personal allowance taper. Your effective marginal tax rate in this range can exceed 60%, meaning a £10,000 gross increase may only yield around £3,800 extra take-home pay.
