The 60% Tax Trap Nobody Warns UK Earners About
UK income tax has three official rates: 20%, 40%, and 45%. But there is an unofficial 60% effective rate that silently hits people earning between £100,000 and £125,140 — and most people earning in this range have no idea it exists. Here is what happens: for every £2 you earn above £100,000, HMRC quietly removes £1 from your Personal Allowance. Since that lost allowance would have been tax-free, losing it while also being in the 40% bracket means you pay 40% tax on the extra income and 40% on the allowance that disappeared. The combined result: 60p lost for every extra £1 earned in this range. A £5,000 bonus that takes your income from £100,000 to £105,000 leaves you with just £2,000 in your pocket.

Salary Sacrifice: The Legal Route Out of the 60% Trap
If your salary is between £100,000 and £125,140, pension contributions via salary sacrifice reduce your gross pay before PAYE is calculated. Every £1,000 contributed to your pension in this band saves you £600 in tax — not £400 like normal 40% taxpayers. A £25,140 pension contribution from £125,140 takes your effective income back to £100,000 and restores your entire Personal Allowance, saving approximately £15,084 in income tax alone.
