💡 The Infamous 60% Marginal Tax Trap (£100k – £125,140)
For every £2 you earn over £100,000, you lose £1 of your £12,570 Personal Allowance. Combined with 40% Higher Rate Tax and 2% National Insurance, this creates an effective 60% to 62% marginal tax rate on earnings between £100,000 and £125,140. Putting any pay rise or bonus into a private pension (SIPP) recovers your full personal allowance and saves 60% in tax!
