How to avoid paying 40% tax?
Avoiding the 40% tax bracket in the UK is possible through legal, HMRC-approved strategies such as increasing pension contributions, using ISAs, and making charitable donations via Gift Aid. With frozen income tax thresholds set to remain in place until at least 2028, more people than ever are being pulled into the higher rate band, making tax planning an essential part of managing your finances.
What Is the 40% Tax Bracket and Who Does It Affect?
The 40% tax bracket, officially known as the higher rate income tax band, applies to income between £50,271 and £125,140 for the 2025/26 tax year in England, Wales and Northern Ireland. It is a marginal rate, meaning only the portion of your income that falls within that range is taxed at 40%, not your entire salary.
According to HMRC, nearly 7.1 million people in the UK are expected to pay higher-rate income tax in 2025/26, up from 5.1 million just three years earlier. This sharp rise is largely due to fiscal drag, where frozen thresholds cause more earners to cross into a higher band as wages rise with inflation, even when their real purchasing power has not improved.
| Tax Band | Income Range | Tax Rate |
|---|---|---|
| Personal Allowance | Up to £12,570 | 0% |
| Basic Rate | £12,571 to £50,270 | 20% |
| Higher Rate | £50,271 to £125,140 | 40% |
| Additional Rate | Over £125,140 | 45% |
It is also worth noting that if your income exceeds £100,000, your personal allowance begins to reduce by £1 for every £2 you earn above that threshold. By £125,140, the allowance is gone entirely, creating an effective tax rate of around 60% on income in that range.

How Pension Contributions Help You Avoid 40% Tax
One of the most effective and straightforward ways to reduce your taxable income is to increase pension contributions. Every pound you pay into a pension reduces your adjusted net income, which can keep you below or bring you back under the £50,271 threshold.
For example, if you earn £55,000 and contribute an additional £5,000 into your pension, your taxable income drops to £50,000, pulling you back into the basic rate band. On Reddit’s r/UKPersonalFinance, one user described exactly this approach: paying into a SIPP to avoid 40% tax on the last few thousand pounds of their income, with commenters confirming that the pension provider claims basic rate relief at source, and the additional 20% can be reclaimed from HMRC without needing a self-assessment return.
If your employer offers a salary sacrifice scheme, this is even more efficient as contributions come out of your pre-tax salary, saving on National Insurance as well as income tax. You can contribute up to £60,000 into your pension in the current tax year, and you can carry forward unused allowances from the previous three tax years.
| Strategy | How It Reduces Tax | Annual Limit |
|---|---|---|
| Salary sacrifice pension | Reduces gross income before tax and NI | Up to annual allowance (£60,000) |
| Personal pension / SIPP | Reduces adjusted net income | Up to 100% of earnings |
| Employer contributions | Does not count as taxable income | Within annual allowance |
| Carry forward unused allowance | Extends how much you can contribute this year | Up to 3 prior tax years |
ISAs, Gift Aid and Asset Transfers: Other Ways to Cut Your Bill
Beyond pensions, there are several other legal routes worth considering. Using your annual ISA allowance of £20,000 shields savings interest and investment growth from tax entirely. If you hold shares or funds outside an ISA, the Bed and ISA process allows you to sell and repurchase them inside a tax wrapper, meaning future returns become tax-free. Just be careful to stay within the £3,000 capital gains tax exemption when you sell.
Making charitable donations through Gift Aid is another underused tool. As a higher-rate taxpayer, you can claim back the difference between the basic and higher rate of tax on the gross donation amount. A £1,000 donation becomes £1,250 to the charity, and you can reclaim £250 through self-assessment or by contacting HMRC directly. In some cases, a well-timed donation could take you from just above to just below the higher-rate threshold, reducing your tax on savings and investments at the same time.
If you are married or in a civil partnership, transferring income-producing assets such as savings accounts, shares or rental property into your partner’s name can also be effective, provided they pay tax at a lower rate. This allows the couple to make use of two sets of allowances rather than one.
Salary Sacrifice Schemes and Business Structures
For those still in employment, salary sacrifice schemes offer a practical way to reduce taxable income beyond just pensions. HMRC-approved schemes for electric cars and cycle-to-work programmes allow you to exchange part of your salary for non-cash benefits, reducing the income that is subject to tax and National Insurance in one move.
For self-employed individuals, contractors, or those with multiple income streams, the structure of how you pay yourself matters considerably. Operating through a limited company, for instance, allows you to take a smaller salary within the basic rate band and draw additional income as dividends, which are taxed at a lower rate. The dividend tax rate for higher-rate taxpayers sits at 33.75%, compared to 40% on employment income, and the first £500 of dividends each year remains tax-free. Business owners can also claim allowable expenses such as mileage, equipment, training and home working costs, all of which reduce taxable profit.
For those comfortable with higher-risk investments, the Enterprise Investment Scheme (EIS) offers 30% income tax relief on qualifying investments in early-stage UK businesses, with gains on successful companies exempt from capital gains tax. This is only suitable for confident investors, and professional advice should always be sought beforehand.

Final Thoughts on How to Avoid Paying 40% Tax
With frozen thresholds and rising wages continuing to push more earners into the 40% band, tax planning has never been more important for UK workers and retirees alike. The good news is that the UK tax system provides multiple legal, HMRC-approved routes to reduce your taxable income, many of which also benefit your long-term financial position.
Pension contributions remain the single most powerful tool available to most people, offering immediate tax relief and building retirement savings at the same time. But combining this with ISAs, Gift Aid, salary sacrifice and smart asset management can make a significant difference to how much of your income you actually keep.
Whether you are an employee nearing the threshold, a self-employed professional managing variable income, or a retiree drawing down from a pension pot, a structured approach to tax planning is worth prioritising. If your circumstances are complex, speaking with a qualified independent financial adviser or a specialist accountant is a worthwhile step.
Key takeaways:
- The 40% tax rate only applies to income above £50,270, not your total earnings, so even a small reduction in taxable income can make a meaningful difference
- Pension contributions, ISAs, Gift Aid and salary sacrifice are all fully legal, HMRC-approved methods to bring your adjusted net income below the higher-rate threshold
- If your income sits between £100,000 and £125,140, the gradual loss of your personal allowance creates an effective rate of around 60%, making proactive planning in this range especially valuable
