As the end of the tax year approaches, households in the UK have limited time to review their tax situation properly. If not handled properly, some individuals may fall into a “60% tax trap,” where a portion of their income is effectively taxed at a much higher rate than expected.This situation arises due to how the Personal Allowance system works, often referred to as a “stealth tax” system.

Income Tax Basics
In England and Wales, income tax is generally charged at:
| Income Range | Tax Rate |
|---|---|
| Up to £12,570 | 0% |
| £12,571 – £50,270 | 20% |
| £50,271 – £125,140 | 40% |
| Above £125,140 | 45% |
The Personal Allowance (£12,570) means you don’t pay tax on the first portion income.
Example annual income calculation:
- Tax-free: £12,570
- Taxable: £7,230
- Tax (20%): approx. £1,460
How the 60% Tax Trap Works
When your income exceeds £100,000 threshold level, your Personal Allowance starts reducing.
- For every £2 earned above £100,000, you lose £1 of your allowance.
- This continues until £125,140, where the allowance becomes zero.
Additionally, 2% National Insurance is also applied.
Effective Tax Impact
Between £100,000 and £125,140:
| Component | Percentage |
|---|---|
| Income Tax | 40% |
| Loss of Personal Allowance | 20% |
| National Insurance | 2% |
| Effective Total | ~60%+ |
This creates a situation where a significant portion income is heavily taxed amount.
Example Scenario
If someone earns £101,000:
- Extra £1,000 pushes them into the higher tax bracket
- They lose part of their Personal Allowance
- This results in an effective tax rate close to 60% on that portion
How to Avoid the 60% Tax Trap
There are still ways to reduce exposure before the tax year ends (April 5):
Pension Contributions
- Contributing more to your pension reduces taxable income
- Helps bring income below £100,000 threshold
- Provides additional tax relief
Example:
If you receive a £1,000 bonus:
- Income becomes £101,000
- Contributing £1,000 to pension:
- Keeps income below threshold
- Avoids 60% tax band
- Gains up to 40% tax relief
Conclusion
The 60% tax trap is caused by the reduction Personal Allowance for high earners. Proper planning, especially through pension contributions strategy, can help reduce tax liability and improve long-term financial benefits.
