UK Income Benchmark: 60% Tax Trap Guide (£100k–£125k)
The '60% Tax Trap' is the most punitive marginal rate in the entire UK tax code. Between £100,000 and £125,140, your £12,570 tax-free Personal Allowance is clawed back at 50p for every £1 earned. This produces an effective 60% income tax rate + 2% NI = 62% marginal tax! If you have a Plan 2 student loan, your marginal deduction hits 71%.
Pension Salary Sacrifice Strategy on 60% Tax Trap Guide (£100k–£125k)
The golden solution: Salary sacrifice all earnings between £100,000 and £125,140 into your pension. Sacrificing £10,000 costs you only £3,800 out of pocket while depositing a full £10,000 into your pension pot (an immediate 163% return on invested take-home pay!).
Frequently Asked Questions about 60% Tax Trap Guide (£100k–£125k) After Tax
Why is the tax rate 60% between £100,000 and £125,140?
Under UK legislation, earning £2 over £100k withdraws £1 of Personal Allowance. You pay 40% tax on the extra £2 (80p) plus 40% tax on the lost £1 of allowance (40p), totaling £1.20 in tax on £2 earned — exactly 60%. Adding 2% National Insurance makes it 62%.
How do I avoid the 60% tax trap?
The most effective method is pension salary sacrifice or private SIPP contributions. By contributing your earnings above £100k into a pension, your Adjusted Net Income drops back to £100,000, fully restoring your £12,570 allowance.
Do I lose childcare benefits at £100,000?
Yes. If either parent has an Adjusted Net Income over £100,000, you lose both Tax-Free Childcare (worth up to £2,000/year per child) and the 15/30 hours of free childcare for 9-month-olds to 4-year-olds.
