Avoiding the 60% Tax Trap: Personal Allowance Taper Strategies for High Earners

The so-called “60% tax trap” catches thousands every year, but with the right planning you can keep more of what you earn.

What is the 60% Tax Trap?

In the UK, everyone is entitled to a personal allowance before income tax kicks in. For the 2025/26 tax year the allowance remains £12,570. However, once your adjusted net income exceeds £100,000, the allowance is withdrawn at £1 for every £2 earned. By £125,140 the allowance is gone, giving an effective 60% marginal rate on the slice between £100,000 and £125,140 (40% higher-rate income tax plus 20% lost allowance).

The personal allowance taper is set to stay frozen for 2026/27 according to the latest HMRC announcements, meaning the trap will snare even more earners as wages rise.

Who is Most at Risk?

If your combined salary, bonus, dividends and freelancing profits sit anywhere near the £100k–£140k range, you are squarely in the danger zone. Because the taper uses adjusted net income, it is particularly unforgiving for:

• Consultants billing through a limited company who draw large dividends near year-end.
• Partners in professional firms whose profit shares fluctuate.
• Property sellers realising chunky one-off gains in addition to their day job income.

Six Tried-and-Tested Ways to Escape the 60% Tax Trap

Below are the most reliable tactics to bring your adjusted net income back under £100,000 or at least soften the blow.

1. Boost Pension Contributions (and Mind the Pension Allowance Taper)

Making a pension contribution is the classic defence, because payments are taken off adjusted net income. Contributing just £25,140 reduces income to £100,000, restoring the full personal allowance and creating an effective 60% tax relief.

Be alert, though: high earners face the pension allowance taper. From 2025/26 the standard annual allowance is £60,000. For every £2 of adjusted income over £260,000, the allowance falls by £1, down to a £10,000 floor. Check the HMRC guidance here. Keeping within the tapered limit ensures you still receive full pension tax relief.

Practical tip: Company owners can make an employer pension contribution which additionally saves corporation tax.

2. Use Gift Aid Donations

Gift Aid works similarly to pension contributions in reducing adjusted net income. A £4,000 donation only costs £3,200 after reclaiming higher-rate relief and also chips away at the 60% zone.

3. Exchange Bonus for Employer Pension or Holiday

Salary sacrifice arrangements can swap taxable cash for pension input or additional leave. Structuring next year’s remuneration early with HR prevents a future 60% problem.

4. Time Income & Expenses

If you’re self-employed, accelerating business expenses into the current tax year, or delaying an invoice until 6 April 2026, can shift profit clear of the threshold. The same logic applies to director dividends: vote dividends on 6 April, not 5 April.

5. Offset Rental or Trading Losses

Property investors can carry forward prior-year rental losses to offset current profits, trimming adjusted net income. Careful record-keeping is essential here.

6. Keep Capital Gains Separate – or File Quickly

Selling a buy-to-let can create a significant taxable gain the same year as high earnings, tipping you deeper into the trap. Properly timed exchanges or filing a 60-Day Capital Gains Tax (CGT) return quickly can help you budget for the extra liability and consider reinvestment reliefs such as Business Asset Rollover.

Worked Example: The Consultant Earning £120,000

Emma runs a consultancy and expects £120,000 in profits for 2025/26.

Scenario

1 - No Planning

• ‍Tax & NI Cost: £37,432
• Net Income: £82,568

2 - £20k pension contribution

• ‍Tax & NI Cost: £25,432
• Net Income: £94,568 (+£12,000)

The £20k pension contribution drags Emma out of the taper entirely, restoring the personal allowance and saving her £12k compared to doing nothing.

Keeping Records: The Role of Self Assessment

Anyone with income over £150,000 must file a Self Assessment tax return. Accurate disclosure of pension tax relief, Gift Aid and the personal allowance taper is vital—errors are costly.

Tax Year 2026/27: What We Know So Far

HMRC has signalled the main allowances—including the £12,570 personal allowance and £100,000 taper threshold—will remain frozen in 2026/27. High inflation means more people crossing the line. Planning a year in advance is now a necessity, not a luxury.
