The 60% Tax Trap: Why Earning Over £100,000 Costs You More Than You Think
Between £100,000 and £125,140, every extra £1,000 you earn only puts £380 in your pocket — compared to £580 at £99,000. That’s an effective marginal tax rate of ~60%.
Updated for the 2025/26 tax year. All calculations use current HMRC rates.
What is the 60% tax trap?
Everyone in the UK gets a Personal Allowance of £12,570 — the amount you can earn tax-free each year. However, once your income exceeds £100,000, HMRC claws back this allowance at a rate of £1 for every £2 you earn over £100,000.
This means the Personal Allowance is fully withdrawn at £125,140 (since £12,570 × 2 = £25,140, and £100,000 + £25,140 = £125,140).
Here’s the maths on that extra £1,000 earned at £100,000:
- 40% income tax on the £1,000 = £400
- £500 of Personal Allowance lost (half of £1,000), which was previously tax-free but is now taxed at 40% = £200
- 2% National Insurance (above £50,270) = £20
- Total deducted: £620 out of £1,000 — an effective marginal rate of 62%
This is widely referred to as the “60% tax trap” (the 60% figure excludes NI; with NI included it’s actually 62%).
Example: £110,000 salary
At £110,000, you’ve exceeded the £100K threshold by £10,000. Your Personal Allowance is reduced by £5,000 (half of £10,000), leaving just £7,570 of tax-free income instead of £12,570. You pay £2,000 more tax than you would if the taper didn’t exist.

How to Avoid the 60% Tax Trap
The strategies below all work by reducing your adjusted net income (the figure HMRC uses for the Personal Allowance taper) to £100,000 or below.
1. Pension contributions (salary sacrifice)
The most common and effective strategy. If your employer offers salary sacrifice, you give up gross pay in exchange for pension contributions. This reduces your taxable income before PAYE, so the personal allowance taper never triggers. You effectively get 62% tax relief on contributions in the trap zone — far more than the standard 40% higher-rate relief.
Example: On a £115,000 salary, sacrificing £15,000 into your pension brings your taxable income to £100,000. You restore your full £12,570 Personal Allowance, saving approximately £9,300 in tax. The effective cost of that £15,000 pension contribution is only £5,700.
2. Gift Aid donations
Charitable donations made through Gift Aid extend your basic rate band and reduce your adjusted net income. If you donate enough to bring your income below £100,000, you restore your full Personal Allowance. You need to claim this via Self Assessment.
3. Salary sacrifice for other benefits
Some employers offer salary sacrifice for benefits beyond pensions: cycle-to-work schemes, additional holiday purchases, electric car salary sacrifice (which also has BIK advantages), or technology schemes. These all reduce your gross pay and can help you stay below the £100,000 threshold.
4. Timing of bonuses
If you have some control over when a bonus is paid, timing it across two tax years could keep each year below £100,000. This requires your employer’s cooperation and careful planning.
5. Personal pension contributions
If salary sacrifice isn’t available, you can make personal pension contributions and claim higher-rate relief via Self Assessment. You’ll get the 40% relief on the contribution, plus the Personal Allowance restoration. The net effect is similar, but the cash flow timing is different (you pay upfront and claim relief later).
Pension Sacrifice Calculator
How much pension contribution you need to bring your taxable income to exactly £100,000, and how much tax you save by doing so. All figures assume salary sacrifice (pre-tax).
| Gross Salary | Pension Contribution | Tax Saved | Effective Cost | Take-Home Without | Take-Home With Sacrifice |
|---|---|---|---|---|---|
| £105,000 | £5,000 | £3,100 | £1,900 | £70,457 | £68,557 |
| £110,000 | £10,000 | £6,200 | £3,800 | £72,357 | £68,557 |
| £115,000 | £15,000 | £9,300 | £5,700 | £74,257 | £68,557 |
| £120,000 | £20,000 | £12,400 | £7,600 | £76,157 | £68,557 |
| £125,000 | £25,000 | £15,500 | £9,500 | £78,057 | £68,557 |
Read this column: The “Effective Cost” shows what the pension contribution actually costs you in reduced take-home pay. For a £115,000 earner, a £15,000 pension contribution only reduces your take-home by £5,700 — meaning you get £15,000 in your pension pot for a cost of just £5,700.
Scotland: The 67% Tax Trap
Scotland has its own income tax rates, and the Personal Allowance taper still applies. Because Scotland has a 45% Advanced rate (vs 40% Higher rate in England) in part of the taper zone, the effective marginal rate is even higher — approximately 67% (45% + 20% taper + 2% NI).
