The 60% Tax Trap Explained

What Is the 60% Tax Trap?

The 60% tax trap is one of the most punishing features of the UK tax system, and it catches many people by surprise. It affects anyone with an adjusted net income between £100,000 and £125,140. In this income band, your personal allowance — the £12,570 of income you can earn tax-free — is gradually withdrawn at a rate of £1 for every £2 of income above £100,000.

The result is an effective marginal tax rate of around 60%. For every extra £1 you earn in this band, you pay 40p in income tax (the higher rate) plus you lose 50p of personal allowance, which would otherwise have been taxed at 0% but is now taxed at 40% — costing you an additional 20p. That is 40p + 20p = 60p lost from every additional pound earned. When you factor in National Insurance contributions at 2% for earnings above the upper earnings limit, the effective marginal rate can exceed 62%.

This means someone earning £125,140 can take home only marginally more than someone earning £100,000, despite earning over £25,000 more in gross income.

How the Personal Allowance Taper Works

The personal allowance taper removes £1 of your tax-free personal allowance for every £2 you earn above £100,000. Because the personal allowance is £12,570, it is fully withdrawn once your adjusted net income reaches £125,140 (£100,000 + 2 × £12,570). The table below illustrates how this plays out across the income band.

Who Is Affected?

The 60% tax trap affects anyone whose adjusted net income falls between £100,000 and £125,140. This includes salary, bonuses, benefits in kind, rental income, dividends, and any other taxable income. It is particularly relevant to:

• Senior NHS staff — consultants and senior GPs whose pay often sits squarely in this range, especially with additional programmed activities or locum work
• Senior teachers and headteachers — leadership-scale salaries combined with TLR payments can push income into the trap
• Civil servants approaching higher grades — senior civil service roles and grade 6/7 positions with London weighting
• Professionals receiving bonuses — a base salary of £90,000 with a £20,000 bonus puts you firmly in the trap
• Self-employed with variable income — a strong year can tip you into the band unexpectedly. See our self-employed pension guide for more on managing variable earnings

Strategies to Reduce Your Effective Tax Rate

The good news is that the 60% tax trap is one of the most avoidable tax inefficiencies in the UK system. There are several legitimate strategies to reduce your adjusted net income and restore some or all of your personal allowance.

• Pension contributions — personal pension contributions reduce your adjusted net income. Contributing enough to bring your income below £100,000 restores your full personal allowance. For example, someone earning £120,000 who makes a £20,000 gross pension contribution reduces their adjusted net income to £100,000. The £20,000 contribution attracts 40% higher-rate tax relief (£8,000) plus the restored personal allowance saves a further £4,000 or more in tax. The effective cost of £20,000 going into your pension can be as little as £8,000.
• Salary sacrifice — if your employer offers salary sacrifice for pension contributions, this is even more effective. Your gross salary is reduced before tax and National Insurance are calculated, so both you and your employer save on NICs. The pension contribution never appears as part of your income, making it the cleanest way to bring your adjusted net income below £100,000.
• Gift Aid donations — the gross value of Gift Aid donations extends your basic rate band and reduces your adjusted net income. If you already give to charity, making sure donations are Gift Aid eligible can provide significant tax savings in the £100,000 to £125,140 band. A £1,000 net donation (grossed up to £1,250) reduces your adjusted net income by £1,250.
• Timing of income — if you are self-employed or a company director, you may have some flexibility over when income is recognised. Shifting invoicing dates or dividend declarations between tax years can help keep adjusted net income below £100,000 in a given year. This requires careful planning and professional advice.
• Spreading bonuses — where possible, negotiating with your employer to defer or spread bonus payments across tax years can prevent a single large bonus from pushing you deep into the 60% trap. Even partial deferral can make a meaningful difference.

A Worked Example

Let us walk through a concrete example to show just how powerful pension contributions can be in this income band.

This example shows why the 60% tax trap is often described as the most tax-efficient income band for pension saving in the entire UK tax system. Nowhere else do you get such a large effective return on contributions.

The Pension Annual Allowance Interaction

The pension annual allowance for 2024/25 is £60,000. Since the income band affected by the 60% tax trap is only £25,140 wide (£100,000 to £125,140), the standard annual allowance provides more than enough headroom for most people to contribute their way out of the trap entirely. If you have unused annual allowance from the previous three tax years, you can carry it forward, giving you even more flexibility.

However, if your adjusted income exceeds £260,000, the tapered annual allowance comes into play. The annual allowance is reduced by £1 for every £2 of adjusted income above £260,000, down to a minimum of £10,000. This limits the pension contribution strategy for very high earners. For most people caught in the 60% tax trap — those earning between £100,000 and £125,140 — the tapered annual allowance is not a concern.

Should You Seek Advice?

The 60% tax trap is one of the clearest cases where professional financial advice pays for itself — often many times over. The potential tax savings from optimising your position in this income band can easily run into thousands of pounds per year, far exceeding the cost of advice.

A good financial adviser can model your exact income, pension position, and tax situation to determine the optimal contribution level. They can also coordinate pension contributions with salary sacrifice arrangements, Gift Aid strategies, and income timing to maximise your overall tax efficiency. If you have a defined benefit pension (common in the NHS, teaching, and civil service), the interaction between your scheme contributions and the personal allowance taper adds further complexity that benefits from professional guidance.
