This guide is fully updated for the 2026/27 HMRC tax year. All calculations and tax rules have been audited against official UK legislation.
In the UK tax system, one of the most punitive and least understood tax brackets is the notorious 60% tax trap. This marginal rate affects individuals earning between £100,000 and £125,140. Because of the way the personal allowance is withdrawn, high earners in this bracket face a combined tax rate that is higher than the top rate of tax. In this comprehensive guide, we explain how the 60% tax trap is triggered, calculate its true impact, and outline the legitimate financial strategies to avoid it legally for the 2026/27 tax year.
What is the 60% Tax Trap?
The standard tax-free Personal Allowance is £12,570. However, under HMRC rules, this allowance is tapered for individuals with an **Adjusted Net Income exceeding £100,000**. For every **£2** you earn over £100,000, you lose **£1** of your Personal Allowance. This means your personal allowance is reduced to zero once your income reaches £125,140.
This clawback creates a devastating marginal tax rate: on every £100 you earn in this zone, you pay £40 in income tax, and you also lose £50 of your tax-free allowance, which is now taxed at 40% (costing you an extra £20 in tax). This creates an effective income tax rate of **60%**, which rises to **62%** once employee National Insurance (2% above the Upper Earnings Limit of £50,270) is factored in.
The Impact of the 60% Tax Trap: A Case Study
The table below demonstrates how the taper affect earnings between £100,000 and £125,140 compared to standard brackets:
| Gross Salary Bracket | Standard Marginal Tax Rate | Personal Allowance Remaining | True Marginal Tax Rate (with NI) |
|---|---|---|---|
| £50,271 to £100,000 | 40% | £12,570 | 42% |
| £100,001 to £125,140 | 40% + Allowance Taper | Tapering to £0 | 62% |
| £125,141+ | 45% | £0 | 47% |
How to Avoid the 60% Tax Trap Legally
The key to escaping this trap is to reduce your **Adjusted Net Income** back down to £100,000 or below. Here are the most effective methods to achieve this:
- Make Pension Contributions: Contributing to a workplace pension (via salary sacrifice or net pay) or a personal SIPP reduces your adjusted net income pound-for-pound. For example, if you earn £110,000 and contribute £10,000 into your pension, your taxable income drops to £100,000, completely preserving your £12,570 personal allowance. This contribution effectively gets 60% tax relief!
- Utilize Salary Sacrifice Benefits: Agreeing to exchange cash salary for tax-free or low-tax benefits (like electric company cars or cycle to work schemes) keeps your taxable income below the £100k threshold.
- Make Gift Aid Donations: Donations to registered charities reduce your adjusted net income, extending your basic rate tax band and restoring tapered allowances.

What People Search For: FAQs on the 60% Tax Trap
1. What is the 60% tax trap in the UK?
The 60% tax trap is a nickname for the 60% marginal income tax rate that applies to earnings between £100,000 and £125,140. It is caused by the combination of the 40% Higher Rate tax and the phasing out of the £12,570 Personal Allowance.
2. At what salary does the personal allowance start tapering?
The Personal Allowance starts tapering as soon as your Adjusted Net Income exceeds £100,000. It is reduced by £1 for every £2 of income over this limit, disappearing completely at £125,140.
3. How does a pension contribution help avoid the 60% tax trap?
Pension contributions reduce your Adjusted Net Income. If you earn £115,000 and pay £15,000 into a SIPP or occupational pension, HMRC calculates your tax as if you earned £100,000, restoring your full Personal Allowance.
4. What is Adjusted Net Income for tax purposes?
Adjusted Net Income is your total taxable income (including salary, bonuses, interest, dividends, and rental profits) minus gross pension contributions and gross Gift Aid donations. It does not include capital gains.
5. Does a charity donation reduce the 100k tax trap?
Yes. Gift Aid donations to registered charities reduce your Adjusted Net Income pound-for-pound, helping you stay under the £100,000 threshold and recover your tapered Personal Allowance.
6. What happens to the tax-free childcare allowance at £100,000?
If either parent’s Adjusted Net Income exceeds £100,000, the household loses all eligibility for Tax-Free Childcare (up to £2,000 per child per year) and the 30 hours of free childcare scheme. This is a severe secondary cliff-edge penalty.
7. Can I split my income with my spouse to avoid the £100k tax trap?
If you are employed, you cannot split your wage. However, if you run a limited company or own joint income-generating assets (like rental property), you can distribute shares or transfer assets to your spouse to balance your incomes under £100k.
8. Does company car Benefit-in-Kind count towards the £100k limit?
Yes. The taxable value of any company benefits (Benefit-in-Kind), such as medical insurance, company cars, or fuel allowances, is added to your cash salary to calculate your Adjusted Net Income.
9. Can I use salary sacrifice to stay under £100,000?
Yes. Entering into a salary sacrifice arrangement for an electric car, cycle to work equipment, or childcare vouchers lowers your contractual gross salary, helping to keep you below the £100,000 personal allowance taper limit.
10. Do capital gains count towards the £100,000 personal allowance taper?
No. Capital gains are kept separate from income tax calculations and do not affect your Adjusted Net Income. However, dividend income and savings interest do count, so they can push you into the taper zone.
