The UK 60% Tax Trap Explained 2026/27
Between £100,000 and £125,140, your effective marginal tax rate isn't 40% — it's 60%. This is because the Personal Allowance tapers away. It's the single most expensive UK tax band, and most candidates I've placed at this income level don't know it exists. Here's how it works and how to escape it.
How the maths works
The UK Personal Allowance is £12,570/year — the amount of income everyone (in theory) can earn tax-free. But for high earners, this allowance is "tapered" away:
- • Below £100,000: full Personal Allowance applies (£12,570).
- • Between £100,000 and £125,140: Personal Allowance reduces by £1 for every £2 earned above £100k.
- • Above £125,140: Personal Allowance is zero — fully tapered away.
So if you earn £110,000, your Personal Allowance has been reduced by (10,000 ÷ 2) = £5,000. You now have only £7,570 of tax-free income instead of £12,570. The extra £5,000 that's no longer tax-free gets taxed at 40% = £2,000 extra tax on top of the standard 40%+2% on that £10k.
That extra hit on the lost Personal Allowance is what pushes the effective marginal rate from 42% (income tax + NI) to roughly 60%.
The full effective marginal rate breakdown
| Income band | Income tax | Employee NI | Effective marginal |
|---|---|---|---|
| £0 – £12,570 | 0% | 0% | 0% |
| £12,570 – £50,270 | 20% | 8% | 28% |
| £50,270 – £100,000 | 40% | 2% | 42% |
| £100,000 – £125,140 | 40% + PA taper | 2% | ≈60% |
| £125,140 – above | 45% | 2% | 47% |
The 47% marginal rate above £125,140 is actually lower than the 60% in the trap below it. Going from £100k to £125k feels like a £25k pay rise but on net costs you about £15k in extra tax (60% effective). Going from £125k to £150k feels like a £25k pay rise that costs you £11.75k (47%) — significantly less per £.
Worked example — £125,140 vs £100,000 + £25,140 pension
The classic salary-sacrifice fix. Same total compensation, very different tax outcome:
| Approach | Take-home | Pension | Total benefit |
|---|---|---|---|
| £125,140 base, no sacrifice | ~£78,400 | £0 (your contribution) | £78,400 |
| £100,000 base + £25,140 pension | ~£68,400 | £25,140 | £93,540 |
By sacrificing the £25,140 above £100k into pension instead of receiving it as salary, you keep £93,540 of total economic benefit (£68k take-home + £25,140 pension) instead of just £78,400. That's £15,140 of extra value per year — purely from avoiding the 60% trap.
Plus, your employer saves 13.8% employer NI on the sacrificed amount (about £3,500/year). Many employers will pass that saving back as additional pension contribution if you ask — making the win even bigger.
Other ways to beat the trap
- 1. Salary sacrifice for pension (best). Already covered above.
- 2. Salary sacrifice for EV company car. Benefit-in-kind rate on EVs is 3% in 2026/27 — extremely tax-efficient. Sacrifice £10k of salary, get a £50k EV; your taxable income drops by £10k and you only pay BiK on the (3% × P11D) = small.
- 3. Salary sacrifice for cycle-to-work / EAP / childcare. Smaller amounts but each pound counts when in the 60% band.
- 4. Increase Gift Aid donations. Gift Aid donations extend your Basic Rate band, which can pull income out of the 40% band entirely (and indirectly preserve more PA).
- 5. Bonus deferral — if your bonus tips you into the trap, ask for it to be deferred to a future tax year, paid as pension contribution, or split across years. Most UK employers will accommodate this.
- 6. Spousal income shifting — if your spouse earns under £100k, transferring income-generating assets to them can keep household income below trap thresholds. Marriage Allowance only helps if one partner is under PA.
When it makes sense to ignore the trap
Three scenarios where taking the 60% hit can be the right call:
- • You need the cash now — pension is locked until 55+ (rising to 57+ from 2028). If you have urgent short-term cash needs (deposit, school fees, debts), salary sacrifice is the wrong answer regardless of tax rate.
- • You're already at the £60k pension annual allowance (and have no carry-forward room) — extra contributions trigger Annual Allowance tax charges that erase the benefit.
- • Your pension provider has high charges — if your workplace pension has a 1%+ AMC, the long-term cost can outweigh the upfront tax saving.
For most £100-125k earners with normal financial circumstances, the trap is genuinely worth fixing. The cumulative impact across a career is enormous — at £15k saved per year for 10 years that's £150k of tax preserved, before pension growth.
FAQs
- What income range is the 60% tax trap?
- £100,000 to £125,140 in the rest of UK. Above £125,140 the trap ends because Personal Allowance is fully tapered (you're at 47% effective).
- Does the 60% trap apply in Scotland?
- Yes, but with Scottish income tax bands (42% Higher rate vs 40% rUK), the effective rate in the trap is closer to 65%. The fix is identical: salary sacrifice into pension.
- Does bonus count towards the 60% trap?
- Yes. Total taxable income (salary + bonus + benefits-in-kind + dividends from connected companies) determines whether you're in the trap. A £95k base with a £20k bonus puts £15k of your total in the trap.
- Does pension contribution by my employer count against the trap?
- Employer pension contributions don't count as your income, so they don't push you into or out of the trap. Salary sacrifice (you giving up salary in exchange for employer pension contribution) does reduce your taxable income — that's why it works.
