The 60% tax trap is a stealth income tax bracket affecting UK earners with adjusted net income between £100,000 and £125,140. For every £2 earned above £100,000, HM Revenue & Customs tapers away £1 of your statutory Personal Allowance. Combined with the 40% Higher Rate of Income Tax and 2% employee National Insurance, this withdrawal creates a punishing effective marginal deduction rate of 62% in England, Wales, and Northern Ireland (and up to 70% in Scotland).

Key 2026/27 Statutory Facts & Thresholds
- Standard Personal Allowance: £12,570 statutory tax-free income allowance (frozen through 2030/31). [Source: GOV.UK]
- Taper Starting Threshold: £100,000 of adjusted net income under Section 35 of the Income Tax Act 2007.
- Withdrawal Rate: £1 of Personal Allowance is lost for every £2 of income above £100,000.
- Full Zero-Allowance Point: £125,140 (£100,000 + (2 × £12,570)). Above £125,140, your tax-free allowance is completely £0.00.
- Effective Marginal Rate: 60% Income Tax (40% higher rate + 20% allowance clawback) + 2% employee Class 1 NICs = 62% total marginal tax deduction in England, Wales, and Northern Ireland.
- Scotland Variation: Scottish Higher Rate is 42% and Advanced Rate is 45%. Adding the 20% taper creates marginal tax rates of 64% to 67% (+ 2% NICs = 66% to 69%).
- Childcare Cliff Edge: Crossing £100,000 by even £1 also strips eligibility for 15/30 hours of free childcare and the £2,000/year Tax-Free Childcare top-up per child.
How the 60% Tax Trap Works: The Mechanics Explained
Most taxpayers assume the UK income tax system progresses smoothly from 20% (Basic Rate) to 40% (Higher Rate) and finally 45% (Additional Rate). However, Parliament introduced a hidden clawback mechanism under Section 35 of the Income Tax Act 2007 that distorts this curve entirely.
When your adjusted net income crosses £100,000, two deductions happen simultaneously on every £100 of additional earnings:
- You pay £40.00 (40%) in Higher Rate Income Tax on the £100 itself.
- You lose £50.00 of your tax-free Personal Allowance (£1 per £2 earned). That previously untaxed £50 is now pushed directly into the Higher Rate bracket, creating an additional £20.00 (40% × £50) of tax.
Combined, you pay £40 + £20 = £60.00 in Income Tax on a £100 pay rise — an effective 60% income tax rate. Adding 2% employee Class 1 National Insurance brings the total statutory loss to 62%, leaving you with just £38 from every £100 earned.
Fully Worked Example: £100,000 vs £110,000 Salary
Consider an employee in England who receives a £10,000 salary increase from £100,000 to £110,000 in the 2026/27 tax year. Here is the exact line-by-line statutory maths:
| Deduction Component | At £100,000 Salary | At £110,000 Salary | Marginal Impact on £10k Rise |
|---|---|---|---|
| Gross Contractual Earnings | £100,000.00 | £110,000.00 | +£10,000.00 |
| Statutory Personal Allowance | £12,570.00 | £7,570.00 (£12,570 − £5,000 taper) | -£5,000.00 Lost Allowance |
| Basic Rate Tax (20% on £37,700) | £7,540.00 | £7,540.00 | £0.00 |
| Higher Rate Tax (40%) | £19,892.00 (on £49,730) | £25,892.00 (on £64,730) | +£6,000.00 (60.0% Tax) |
| Total Income Tax Due | £27,432.00 | £33,432.00 | +£6,000.00 |
| Employee National Insurance (2%) | £4,010.60 | £4,210.60 | +£200.00 (2.0% NI) |
| Annual Net Take-Home Pay | £68,557.40 | £72,357.40 | +£3,800.00 (38.0% Kept) |
| Total Deductions Suffered on the Extra £10,000 | -£6,200.00 (62.0% Marginal Rate) | ||
The Takeaway: Out of a £10,000 promotion or bonus, you surrender £6,200.00 to HMRC and keep just £3,800.00 (£316.67 per month).
How to Legally Beat the 60% Tax Trap
The Personal Allowance taper is calculated strictly against your adjusted net income, not your gross contractual remuneration. Adjusted net income is total taxable income minus allowable gross deductions — primarily pension contributions and Gift Aid donations.
This statutory rule allows three highly effective strategies to legally bypass the trap:
1. Workplace Pension Salary Sacrifice
By entering a salary sacrifice arrangement with your employer, you exchange cash salary for employer pension contributions. Because your gross contractual earnings are reduced before payroll runs, your adjusted net income drops pound-for-pound.
If you earn £110,000 and sacrifice £10,000 into your workplace pension:
- Your adjusted net income returns to exactly £100,000.00.
- You completely restore your full £12,570 Personal Allowance.
- You save £4,000 in Higher Rate tax, £2,000 in restored allowance relief, and £200 in employee NI.
- Your pension pot receives £10,000.00 at an effective net cost to you of just £3,800.00 (an immediate 163% return on net cash forfeited).

2. Personal Pension Contributions (SIPP)
If your employer does not offer salary sacrifice, you can make private contributions into a Self-Invested Personal Pension (SIPP) using post-tax income. Under HMRC rules:
- To eliminate £10,000 of excess income, you pay £8,000 net into your SIPP.
- Your pension provider reclaims £2,000 (20% basic rate relief) from HMRC, bringing the gross contribution to £10,000.
- On your Self Assessment tax return, you declare the £10,000 gross contribution. HMRC widens your basic rate band by £10,000 and reduces your adjusted net income to £100,000, issuing a tax refund for the higher rate relief and restored Personal Allowance (£4,000).
- Your net cost is £8,000 − £4,000 refund = £4,000 (slightly higher than salary sacrifice because employee NI is not refunded).
3. Gift Aid Charitable Donations
Donations made to UK-registered charities through Gift Aid also reduce your adjusted net income. Gross Gift Aid donations (net cash multiplied by 100/80) are deducted from your total income when testing the £100,000 threshold. For high earners facing the taper who already donate to charity, declaring Gift Aid on Self Assessment can claw back substantial tax-free allowance.
Scotland Differences: Even Higher Marginal Rates
Because the Scottish Parliament sets devolved income tax bands, taxpayers in Scotland face an even steeper cliff edge. In Scotland, the Higher Rate is 42% (between £43,662 and £75,000) and the Advanced Rate is 45% (between £75,000 and £125,140).
Between £100,000 and £125,140 in Scotland:
- Income Tax is 45% on earnings + 21.5% from the Personal Allowance clawback (since the restored allowance relieves 45% tax on the bottom slice).
- This produces a Scottish marginal income tax rate of 67.5%. Adding 2% employee NI pushes the total marginal deduction rate to 69.5%.
- Scottish high earners keep barely 30p from every additional pound earned in this window.
Frequently Asked Questions
Who pays 60% tax in the UK?
Anyone in England, Wales, or Northern Ireland with an adjusted net income between £100,000 and £125,140 effectively pays 60% Income Tax. This band affects employees receiving pay rises or bonuses, landlords, sole traders, and contractors whose total income enters the taper zone. In Scotland, the effective marginal rate in this band is even higher at 67% to 69.5%.
Does anyone actually pay 60% tax in the UK?
While HMRC has no official headline tax bracket called the ‘60% rate’, hundreds of thousands of UK taxpayers pay an effective 60% Income Tax rate in practice. This occurs because the statutory withdrawal of the tax-free Personal Allowance (£1 per £2 over £100,000) adds 20% on top of the 40% Higher Rate, plus 2% employee National Insurance, creating a 62% marginal deduction.
What is the 60% tax trap in the UK?
The 60% tax trap occurs on income between £100,000 and £125,140. For every £2 you earn above £100,000, HMRC reduces your tax-free Personal Allowance by £1. This clawback adds an effective 20% tax charge on top of the 40% Higher Rate, creating a 60% marginal Income Tax rate (62% including 2% employee National Insurance).
At what exact salary do you lose all of your Personal Allowance?
In 2026/27, the standard Personal Allowance is £12,570. Because it tapers away by £1 for every £2 earned above £100,000, it is completely eliminated once your adjusted net income reaches exactly £125,140 (£100,000 + [£12,570 × 2]). Above £125,140, you pay the 45% Additional Rate with zero Personal Allowance.
Is it better to earn £99,000 or £100,000 in the UK?
On taxable salary alone, you never take home less cash by earning £100,000 instead of £99,000; you still keep 58p per extra pound. However, exceeding £100,000 by even £1 triggers the loss of Tax-Free Childcare (worth up to £2,000 per child) and 30 hours funded childcare, which can cause an absolute net cash loss of several thousand pounds.
Can pension contributions avoid the 60% tax trap?
Yes. Paying into a pension via salary sacrifice or personal contributions reduces your ‘adjusted net income’. For example, if you earn £110,000 and contribute £10,000 gross into a pension, your adjusted net income drops back to £100,000, completely restoring your £12,570 Personal Allowance and delivering an effective 62% tax relief.
How does Gift Aid help beat the 60% tax trap?
Charitable donations made under Gift Aid reduce your adjusted net income in the exact same way as pension contributions. When you donate £80 to charity, the charity claims £20 from HMRC, making a gross donation of £100. This £100 gross donation reduces your adjusted net income by £100, restoring £50 of your Personal Allowance.
Does the 60% tax trap affect childcare support?
Yes. HMRC applies a strict £100,000 adjusted net income ceiling for both Tax-Free Childcare (up to £2,000/year per child) and 30 hours funded free childcare (worth £5,000+ per child). Crossing £100,000 by just £1 strips away entitlement to both benefits, creating a massive fiscal cliff edge for working parents.
What is the marginal tax rate in Scotland above £100k?
Scottish taxpayers face an even steeper cliff edge. In Scotland, income between £100,000 and £125,140 is taxed at the 45% Scottish Advanced Rate plus the 48% Top Rate on the top £140. With the 20% Personal Allowance clawback and 2% employee National Insurance, the effective Scottish marginal tax rate reaches 67% to 69.5%.
Do company benefits count towards the £100k threshold?
Yes. Benefits in Kind (BiK) reported on Form P11D — such as company cars, private medical insurance, and beneficial loans — are treated as taxable employment income. If your base salary is £98,000 and you have £3,000 of P11D benefits, your adjusted net income is £101,000, dragging you into the taper zone.
Is it better to take dividends or salary if I earn over £100,000?
For business owners, dividends are subject to the same £100,000 adjusted net income taper as salary. However, retaining profits inside your limited company or making direct employer pension contributions avoids personal extraction altogether, completely bypassing the 60% tax trap while saving Corporation Tax.
How does the Personal Savings Allowance interact with the taper?
Higher Rate taxpayers normally receive a £500 Personal Savings Allowance (tax-free savings interest). However, once your income exceeds £125,140 and you enter the Additional Rate band, your Personal Savings Allowance drops to £0. All savings interest then becomes taxable at the 45% Additional Rate.
How do I work out my own marginal tax rate?
Your marginal tax rate is the total percentage of tax and National Insurance deducted from your next pound of earnings. For basic-rate employees, it is 28% (20% IT + 8% NI). For higher-rate employees earning under £100,000, it is 42% (40% IT + 2% NI). Between £100,000 and £125,140 (as detailed in our 2026/27 Take-Home Pay Table), it spikes to 62% in England and Wales.
Is salary sacrifice better than SIPP contributions for beating the trap?
Yes. Both methods reduce your adjusted net income pound-for-pound to restore your Personal Allowance. However, salary sacrifice also saves 2% in employee National Insurance on earnings above £50,270, and may allow your employer to reinvest their 15.0% secondary NIC savings back into your pension pot.
