The 60% Tax Trap 2026/27 | How It Works & How to Avoid It

The 60% tax trap hits anyone with adjusted net income between £100,000 and £125,140 in 2026/27. Inside that band, your Personal Allowance of £12,570 reduces by £1 for every £2 you earn, so a chunk of income that would have been tax-free gets dragged into the 40% higher-rate band. Add the taper effect on top of the headline rate and your effective marginal rate lands at 60% — before National Insurance pushes it to 62%.

The trap is pure arithmetic, not a special penalty rate, and it is avoidable. Pension contributions, salary sacrifice and Gift Aid donations all reduce adjusted net income and can restore part or all of your allowance.

How the Personal Allowance Taper Works

For 2026/27 your Personal Allowance stays at £12,570, but it reduces by £1 for every £2 your adjusted net income exceeds £100,000. Adjusted net income is your total taxable income — salary, bonuses, self-employment profits, rental income, gross dividends, savings interest — minus certain deductions such as pension contributions and Gift Aid donations.

The pattern is easy to see: every £2 of extra earnings removes £1 of tax-free allowance, and that £1 is then taxed at 40%. Between £100,000 and £125,140 you pay 40% on the earnings themselves plus an effective 20% on the allowance you lose, giving the headline 60%. Because employee National Insurance on earnings above £50,270 is 2%, the true marginal rate on salary in the trap is 62% — you keep only £380 of every extra £1,000.

Who Is Caught in the Trap

• Salaried employees with total taxable pay between £100,000 and £125,140, including anyone whose bonus or commission pushes them over the threshold.
• Self-employed professionals whose profits land in the band; the taper is calculated on trading profit, so a strong year can trigger it even if other years are lower.
• Dividend and interest recipients — dividends and savings interest count towards adjusted net income, so investment income can tip you into the taper.
• Couples — the allowance is tapered per person, not per household, so both partners can be in the trap independently.
• Anyone near the boundary — a £99,000 salary plus a £2,000 side income crosses £100,000 and starts losing allowance.

The critical point is that the taper looks at adjusted net income, not just PAYE salary. That is why pension contributions made personally or via salary sacrifice are the standard remedy: they reduce the figure HMRC tests against £100,000. The exact relief depends on the pension method, tax position and annual-allowance rules.

Real Example: Anna on £120,000

Anna earns £120,000 in 2026/27 with no other income. Her Personal Allowance is £12,570 − (£120,000 − £100,000) ÷ 2 = £2,570, so £117,430 is taxable.

Now add £1,000 of extra income, taking her to £121,000. Her allowance drops by £500, so £500 more is taxed at 40% (£200) plus the £1,000 itself at 40% (£400), and NI takes £20. Anna keeps £380 of that £1,000 — a 62% marginal rate. A bonus of £10,000 in the trap therefore nets her just £3,800.

The Pension Contribution Fix

Pension contributions reduce adjusted net income pound for pound, restoring allowance as income falls back through the band. Anna contributes £20,000 to her pension:

Salary sacrifice is even better because it also saves the 2% employee National Insurance on the sacrificed amount, and your employer saves 15% secondary NI which they may share with you. A £10,000 bonus sacrificed straight into a pension avoids £6,000 of income tax and £200 of NI — the full £10,000 lands in your pension rather than £3,800 in your bank account.

Other Ways to Stay Below £100,000

• Gift Aid donations — extend your basic-rate band and reduce adjusted net income, so donations up to the point where income reaches £100,000 earn effective 60% relief.
• Salary sacrifice benefits — cycle-to-work schemes and pension sacrifice reduce gross pay; most other benefits in kind do not count as deductions for the taper.
• Income timing — directors can defer bonus or dividend payments into a lower-income year; contractors can align invoices across tax years.
• Other allowances — Marriage Allowance does not stop the Personal Allowance taper. Check any Blind Person's Allowance separately rather than assuming that every allowance is tapered in the same way.

Common Misconceptions About the Trap

Several myths cause people to overpay by ignoring the taper. The first is that the trap only affects salaried employees — in fact any mix of income counts, so a landlord with £90,000 of salary plus £25,000 of rental profit is fully inside it. The second is that earning more is never worth it: the 60% rate applies only between £100,000 and £125,140, so once income clears £125,140 the marginal rate falls back to 45% (plus 2% NI), and the additional-rate taxpayer keeps 53p in the pound rather than 38p. There is a perverse zone around £125,140 where earning slightly more leaves you with more after tax than stopping just below — the taper does not create a cliff where extra income is fully confiscated.

The other persistent myth is that ISA income can push you into the trap. It cannot: income inside an ISA is tax-free and excluded from adjusted net income. Taxable savings interest is different: it is included in the income calculation even where a Personal Savings Allowance means no Income Tax is due on part of it. Gross taxable dividends also count. Get the calculation right before the tax year ends: a pension contribution made in March 2027 can still count for 2026/27, subject to the pension scheme's processing and annual-allowance rules.

Build the adjusted-net-income figure carefully

Start with taxable income for the tax year, then apply the deductions that HMRC includes in its adjusted-net-income calculation. Add salary, bonuses, taxable benefits, trading profits, property income, savings interest and dividends where relevant. Check whether pension contributions, Gift Aid, trade losses or other permitted deductions alter the figure. Do not add ISA returns merely because they appear on an investment statement, and do not remove taxable interest merely because the Personal Savings Allowance means no tax is currently due on part of it.

Keep a schedule by source and tax year. A payslip can show employment income but not a later dividend, rental profit or taxable benefit. A bonus paid after 5 April belongs to the later tax year even if it relates to earlier performance. A pension contribution may reduce adjusted net income, but the relief method, payment date, annual allowance and scheme processing all need to be confirmed. Use the HMRC definition and retain the documents supporting each entry.

Pension limits and salary sacrifice checks

The £60,000 annual allowance is not a universal amount that every person can contribute without further review. Employer contributions, personal contributions, defined-benefit input, carry-forward, tapered annual allowance and the money purchase annual allowance can change the available room. A contribution that restores the Personal Allowance may still create an annual-allowance issue or interact with a pension access decision.

Salary sacrifice is a contractual change to employment pay, not merely a transfer made after payday. Confirm that the employer accepts bonus sacrifice, that the election is made before the relevant entitlement or payment under the scheme rules, and that the pension provider receives the intended amount. Compare employer National Insurance sharing, workplace benefits, statutory pay and mortgage affordability before deciding. A personal contribution has a different relief and evidence trail; do not describe the two methods as identical.

Regional and household checks

The Personal Allowance taper is a UK-wide allowance calculation, but the tax on the remaining income can differ for Scottish taxpayers because Scotland has its own Income Tax bands. National Insurance, dividend tax, pension relief and employer payroll treatment also depend on the income type and taxpayer circumstances. A calculator using England and Northern Ireland rates cannot be treated as a Scottish result.

The taper is assessed per person. A couple should calculate each person's adjusted net income separately, including income held personally, rather than pooling the household total. One partner's pension contribution does not restore the other's Personal Allowance. Keep separate schedules for salary, benefits, investments, Gift Aid and pension contributions before making a joint household decision.
