Warning: the 60% trap applies here, you keep only 38p per pound
This salary range crosses the £100,000-£125,140 Personal Allowance taper, where your effective marginal rate reaches 60%. For every £2 earned above £100,000, your Personal Allowance shrinks by £1, creating a 60% effective tax rate. The additional £3,800 take-home on £10,000 extra gross reflects this, consider pension contributions to reduce gross income into a lower band.
The 60% tax trap, Personal Allowance taper (£100,000-£125,140)
Between £100,000 and £125,140, you lose £1 of Personal Allowance for every £2 earned. That means every £2 extra gross generates £1 of newly taxable income on top of the normal 40% charge, an effective marginal rate of 60%. This range is sometimes called the "60% trap".
One common solution: increase pension contributions to bring taxable gross below £100,000, restoring the full Personal Allowance and dropping back to a 40% marginal rate.
