The “60% tax trap” is the name given to a feature of the UK tax system that often surprises people when they start earning over £100,000.
The 60% tax trap affects people in the UK whose adjusted net income is between £100,000 and £125,140 (using current income tax thresholds).
Those most commonly affected include:
Many people don’t realise they’re affected until they complete a tax return or notice that a pay rise has resulted in a much smaller increase in their take-home pay than expected. Because the loss of the Personal Allowance isn’t always obvious, it’s often referred to as a “tax trap.”
You won’t find the 60% figure talked about officially in HMRC materials.
| Tax band | Taxable income | Income 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% |
The 60% figure arises when two features of the tax system interact: the higher-rate income tax band, and the gradual withdrawal of the Personal Allowance once your adjusted net income exceeds £100,000.
These figures are correct as of 06/04/2026.
Aside from a few exceptional cases, all UK earners get a “Personal Allowance”. This is the amount of income you can earn each tax year before you start paying income tax.
Currently, that’s £12,570.
So, for example:
However, once your income passes £100,000, your Personal Allowance starts to diminish. And by £125,140, it’s gone completely.
That means, you end up paying tax on a greater proportion of your earnings.
How much more?
For every £2 you earn above £100,000, you lose £1 of your allowance.
So, although you’ll still officially be paying 40% income tax as a higher-rate taxpayer, your effective marginal income tax rate – the amount you pay on that particular slice of income – becomes 60%.
Neither. It’s what is known as adjusted net income.
Adjusted net income = total pre-tax income on anything you earn that should be taxed (e.g. salary, rental income, dividends) minus any pension contributions and Gift Aid charity donations. Some trading losses can also lower your adjusted net income.
Loss of free childcare allowance
Parents face a double hit. If either parent earns over £100k, you lose eligibility for:
⚠️ Tax-free childcare
⚠️ 30 hours of free childcare (all or half, depending on your child’s age)
Add in the loss of Child Benefit (fully gone at £80k), and childcare costs can rocket.
Example
You have a two-year-old and a four-year-old. Your salary rises from £99,999 to £104,999. That additional £5,000 means you:
💸 Lose £1,000 of Personal Allowance
💸 Lose £2,000 in tax-free childcare
💸 Lose 30 hours funded care for your two-year-old
💸 Lose half the 30 hours for your four-year-old
Combined, that could leave you £22,593 worse off in a year.
If you’re a parent and you or your partner have an income of over £100k per year, then it is even more important that you understand the 60% tax trap – and the legitimate ways to avoid it.
The good news is there are perfectly legitimate ways to avoid paying this inflated tax rate!
1️⃣ Increase pension contributions
The most common method is to increase pension contributions.
Contributing more to your pension can bring you back under that key £100,000 threshold and mean you boost your retirement income at the same time.
Potential downsides:
❌ The money from your wage increase is locked away until retirement
❌ Tax relief is limited to £60,000 (less if you’re a very high earner)
⚖️ If your salary is just over £100,000, there may be more benefits to this approach than negatives. However, if your salary is much higher, the negatives could outweigh the positives.
2️⃣ Use salary sacrifice schemes
Salary sacrifice is an arrangement where you agree to give up part of your salary in exchange for an employer-provided benefit, such as pension contributions, an electric company car, gym membership, private health cover, laptops, phones or childcare.
Because your salary is lower, your adjusted net income is reduced too.
If your employer offers salary sacrifice arrangements, this can help you keep your income out of that £100k danger zone.
3️⃣ Make Gift Aid contributions
Ticking that ‘Gift Aid’ box when donating items or money to charity, or buying entry tickets to properties owned by charitable organisations, can help nudge your adjusted net income back down below the £100k threshold again.
4️⃣ Hold back on taking all your income in one go
If a bonus or payment would push you over £100k, ask if it can be split across two tax years.
If your income is £110,000 and you contribute £10,000 to your pension (subject to the pension tax relief rules and your available annual allowance), your adjusted income for this purpose falls back to £100,000.
That restores your full Personal Allowance, meaning you avoid the effective 60% band while also increasing your retirement savings.
Other methods for lowering adjusted net income include making charitable donations through Gift Aid or declaring certain trading losses.
Of course, whether any of these are suitable or appropriate will depend on your personal circumstances.
If your adjusted net income is between £100,000 and £125,140, you could be affected. Remember, that £100,000 is not just your salary. Bonuses, rental income, dividends and other income can all count towards the taxable net income figure that HMRC uses. If you know (or suspect) that you're close to the £100,000 threshold, it's worth checking your income before the end of the tax year so you have time to take action if needed.
Not necessarily. It all depends on your personal circumstances. For many people, increasing pension contributions or using salary sacrifice can be a tax-efficient way to keep their Personal Allowance while boosting their retirement savings. However, the right approach will depend on several factors including your current outgoings, your retirement plans and financial goals. Voluntarily taking money out of your monthly income flow in order to put more into your pension might not make sense if you have immediate financial commitments and things are tight. If you're unsure, it's worth speaking to a financial adviser.
Yes! If a pay rise or one-off bonus pushes your adjusted net income above £100,000, you may lose some of your Personal Allowance and, if you have young children, certain childcare benefits too. In some cases, the extra tax and lost benefits mean you keep much less of your pay rise than you expected. But there are perfectly legal ways to mitigate those losses. Planning ahead is key.
