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.

Example Scenario

  • 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.
