The 60% tax trap, explained.
If you earn between £100,000 and £125,140, you're handing HMRC about 60p of every additional pound. Here's how the trap works — and the four legitimate ways out.
The 60% tax trap is the effective marginal tax rate paid on income between £100,000 and £125,140. As your Personal Allowance tapers away by £1 for every £2 you earn over £100,000, each extra pound of pay costs you 40p in income tax, 2p in National Insurance, and 20p in lost allowance — a combined 62% rate.
The good news: pension contributions, salary sacrifice, and charitable giving via Gift Aid all reduce your taxable income and can pull you back below £100,000. Each pound diverted to pension in this zone effectively costs you 40p out of pocket — making this the most tax-efficient income band to save in the entire UK system.
The 60% tax trap appears as a sharp spike between £100,000 and £125,140 — the only band in the entire UK system where you keep less of an extra pound earned than at higher incomes.
What the 60% trap actually is
The "60% tax trap" isn't a formal tax band. You won't find it on a HMRC rate card. It's the unintended consequence of a rule introduced in the 2010 Finance Act: above £100,000 of income, your Personal Allowance starts to disappear.
The Personal Allowance — the £12,570 of income you can earn tax-free — reduces by £1 for every £2 you earn above £100,000. By the time your income reaches £125,140, your allowance has tapered to zero and you're back on a normal additional-rate trajectory.
What this looks like in practice: between £100,000 and £125,140, every £1 of additional pay loses 40p to higher-rate income tax, 2p to National Insurance — and crucially, 20p in tax that you suddenly start paying on what was previously your tax-free allowance. The total marginal cost? 62p in tax and NI for every £1 earned.
The maths in plain English
Imagine you earn £100,000 exactly. You receive a £1,000 pay rise, taking you to £101,000. Here's what happens to that £1,000:
| Component | Amount | You keep |
|---|---|---|
| 40% income tax on the £1,000 | −£400 | £600 |
| 2% National Insurance on the £1,000 | −£20 | £580 |
| Personal Allowance lost: £500 (half of £1,000), now taxed at 40% | −£200 | £380 |
| Total kept from £1,000 pay rise | −£620 | £380 |
So a £1,000 gross pay rise puts £380 in your pocket. Multiply that out: £25,140 of pay rise across the entire trap zone — say from exactly £100,000 to exactly £125,140 — gives you just £9,553 in extra take-home pay. The remaining £15,587 is gone.
Once you're past £125,140, the Personal Allowance is fully tapered away and life gets simpler again — every additional £1 of pay attracts the additional rate (45% income tax + 2% NI = 47% marginal). Confusingly, this is cheaper than the 62% rate that applies just below it.
A £130,000 earner keeps more of every extra pound than a £110,000 earner. The 60% trap is the only time in the UK system where earning less means keeping more per pound.
Why the trap exists
The taper was introduced in the 2010 Finance Act under the Coalition Government as part of an effort to ensure that those with the broadest shoulders make a greater contribution. The idea was to claw back the Personal Allowance from high earners who didn't really need a tax-free portion of their income.
What the policymakers didn't fully telegraph was the cliff-edge marginal rate it creates. The taper is so steep that it briefly produces a higher effective rate than the headline additional rate — meaning the 45% band that kicks in at £125,140 is actually a relief compared to the 62% you've been paying just before it.
Two further tweaks have made the trap more painful over time:
- The £100,000 threshold has been frozen since 2010. With CPI inflation since then, the real-terms equivalent today would be roughly £155,000 — meaning many more taxpayers fall into the trap each year as wages rise.
- The Personal Allowance itself has been frozen at £12,570 since 2021/22, currently scheduled to remain frozen until April 2031. Without these freezes, the trap would be smaller and end at a lower income level.
The result: the number of UK taxpayers in the 60% trap zone has roughly tripled since 2010. As of 2026, around 1.4 million people earn between £100,000 and £125,140.
Four legitimate ways out
Every escape route works the same way: reduce your taxable income below £100,000 so the taper doesn't apply. Your gross salary stays the same — you simply divert some of it through a tax-advantaged channel before it hits HMRC's calculation.
1. Pension contributions (most powerful)
Contributing to a pension reduces your taxable income, pound for pound. Salary sacrifice is the most efficient route because it also avoids National Insurance. The annual allowance for pension contributions is currently £60,000, so if you earn £110,000, you can put up to £10,000 into pension to bring your taxable income down to £100,000 — and the £10,000 of pension contribution effectively cost you £3,800 from your pocket (60% relief).
2. Salary sacrifice for non-pension benefits
Cycle-to-work schemes, electric company cars (still very tax-efficient via low BIK rates), and workplace nursery places can all be funded through salary sacrifice — reducing your taxable income while delivering benefits in kind worth their full pre-tax value.
3. Gift Aid (charitable donations)
Donations to UK-registered charities under Gift Aid extend your basic-rate band by the gross amount of the donation. This means more of your income is taxed at 20% rather than 40% — and crucially, donations also reduce your "adjusted net income", which is the figure HMRC uses to determine the Personal Allowance taper. A £8,000 net donation (£10,000 gross with Gift Aid) can pull a £108,000 earner back below £100,000.
4. Income timing
If you have control over when income is received — bonuses, share vesting, freelance invoicing — you may be able to spread it across two tax years to keep your annual income below £100,000 in each. This requires planning and isn't always possible, but for self-employed people or company directors, it's worth thinking about.
Pension contributions: the most powerful lever
Pensions are the most tax-efficient escape because they get hit with the full force of the trap in reverse. Every £1 contributed via salary sacrifice from someone in the trap zone is worth approximately £1 in your pension at a real cost of about 38p — that's relief of around 60%.
Compare this to a basic-rate taxpayer, where the relief is just 20%. Or a standard higher-rate taxpayer, where it's 40%. The 60% trap zone is the single most rewarding income band in which to make pension contributions in the entire UK tax system.
A few practical points:
- Annual allowance: currently £60,000 per year (or your gross salary, whichever is lower). Contributions above this attract a tax charge equal to your marginal rate.
- Carry forward: you can use unused annual allowance from the previous three tax years if you've been a member of a pension scheme during those years. So if you're trying to make a one-off large contribution, the available headroom might be much higher than £60,000.
- Salary sacrifice vs relief at source: salary sacrifice is more efficient because it also saves National Insurance. Confirm with your employer that they offer salary sacrifice — many but not all do. Relief at source still works but recovers the income tax via Self Assessment, not the NI.
- Tapered annual allowance: if your "adjusted income" is over £260,000 and your "threshold income" is over £200,000, your annual allowance starts to taper down (minimum £10,000). Most people in the 60% trap aren't affected by this, but it's worth knowing.
In the 60% trap zone, every £1 contributed to a pension via salary sacrifice is matched by roughly 62p of tax relief — the most tax-efficient pension funding in the UK system.
Scotland's slightly steeper version
The Personal Allowance taper is a UK-wide rule — it's set by Westminster and applies regardless of where in the UK you live. But the income tax rates that interact with it differ in Scotland.
In Scotland, the higher rate is 42% (vs 40% in the rest of the UK) on earnings between £43,663 and £75,000. Above £75,000, the advanced rate of 45% kicks in. So a Scottish taxpayer in the trap zone faces:
- 45% advanced-rate income tax on each additional £1 of pay (because at £100,000+ they're in the advanced band)
- 2% National Insurance
- 20p of Personal Allowance loss, taxed back at 45%
That works out to a Scottish marginal rate in the trap zone of approximately 56% to 63% depending on exact income — slightly different from the 62% in the rest of the UK, and varying as you cross the £75,000 threshold mid-trap.
The escape strategies (pension, salary sacrifice, Gift Aid) work the same way and are similarly powerful in Scotland.
A worked example: £110,000 earner
Let's run the numbers for someone earning exactly £110,000 in 2026/27, England-based, standard 1257L tax code, no other deductions.
Without any planning
| Item | Amount |
|---|---|
| Gross salary | £110,000 |
| Personal Allowance (tapered: £12,570 - £5,000) | £7,570 |
| Income tax (basic + higher + taper effect) | −£32,432 |
| National Insurance | −£4,210.60 |
| Take-home | £73,357.40 |
With £10,000 pension contribution (salary sacrifice)
| Item | Amount |
|---|---|
| Gross salary (after sacrifice) | £100,000 |
| Personal Allowance (full) | £12,570 |
| Income tax | −£27,432 |
| National Insurance | −£4,010.60 |
| Take-home | £68,557.40 |
| + Pension pot increased by | £10,000 |
| Effective total benefit | £78,557.40 |
Notice what happened: by sacrificing £10,000, your take-home pay dropped by only £4,800 (from £73,357 to £68,557) — but your pension pot grew by £10,000. You effectively got a £5,200 government top-up for that £10,000 of pension funding, which is the 60% trap working in your favour.
The same £10,000 pension contribution made by someone earning £80,000 (well below the trap) would only attract 40% relief — saving them about £4,000 in tax for the same contribution. The trap zone is genuinely the sweet spot for pension funding.
Common mistakes
Refusing a pay rise
Some people decline pay rises that would push them into the trap zone. Almost always a mistake. Even at the worst-case 62% marginal rate, you still keep 38p of every £1 — and that money is yours, while the rest funds something useful (NHS, schools, defence). If the pay rise comes with more responsibility you don't want, that's a separate question. But the maths alone never argues for refusing more pay.
Putting everything into pension regardless
Pensions are powerful tax shelters but the money is locked away until at least age 55 (rising to 57 from 2028). If you have high-interest debt, no emergency fund, or near-term cash needs, those should usually be addressed first. Tax efficiency is one input into a financial decision, not the only one.
Forgetting about Gift Aid
If you give regularly to charity, ensuring those donations are made via Gift Aid is essentially free money — both for the charity (they get a 25% top-up) and for you (the donation reduces your adjusted net income, which can rescue your Personal Allowance).
Ignoring "adjusted net income"
The Personal Allowance taper is calculated against your adjusted net income, not your gross salary. Adjusted net income includes most income (employment, self-employment, rental, dividends) but is reduced by pension contributions, Gift Aid donations, and certain other items. Your gross salary might be £108,000 but your adjusted net income could already be £99,500 if you're already contributing to pension. Always work from the right number.
