⚠️ The £100k Tax Trap
At exactly £100,000, you should be aware of the personal allowance taper:
- For every £2 earned above £100,000, you lose £1 of personal allowance
- This creates an effective 60% marginal tax rate between £100k-£125,140
- Your personal allowance is completely eliminated at £125,140
How to Reduce Tax at £100k
- Pension contributions: Salary sacrifice to get below £100k threshold
- Charitable giving: Gift Aid extends your basic rate band
- Cycle to work scheme: Reduces gross salary
Example: Contributing £5,000 to pension could save ~£3,000 in tax due to regaining personal allowance.
