The £100K Tax Trap Explained
At exactly £100K, you keep your full Personal Allowance. But every pound earned above triggers:
| Additional Income | Take-Home | Effective Rate |
|---|---|---|
| £100,000 | £5,603/month | 32.8% |
| £105,000 | £5,749/month (only +£146) | 62% marginal |
| £110,000 | £5,894/month (only +£145) | 62% marginal |
| £125,140 | £6,502/month (all PA lost) | 47% marginal |
Why This Happens
For every £2 earned above £100K, you lose £1 of Personal Allowance:
- 40% income tax
- 20% effective tax from PA loss (40% × £1 lost allowance)
- 2% National Insurance = 62% marginal rate
