Why the marginal rate drops at £125,140
The 60% rate only exists within the taper zone: £100,000 to £125,140. That is a £25,140 window.
Once your ANI passes £125,140, there is no more Personal Allowance left to lose. The taper penalty disappears.
But that does not mean your marginal rate drops to 40%. In England, Wales and Northern Ireland, income above £125,140 is taxed at 45%. In Scotland, the top rate above £125,140 is 48%.
This is why the trap "ends" at £125,140, but your tax bill can still feel high after that.
Tax rates above £125,140
| ANI band | Rate (England/Wales/NI) | Rate (Scotland) |
|---|---|---|
| £100,000 to £125,140 | Effective 60% (taper zone) | Effective 60%+ (taper zone) |
| Above £125,140 | 45% (additional rate) | 48% (top rate) |
Employee NI of 2% also applies on earnings above the Upper Earnings Limit (£50,270 for 2026/27), though this is collected through PAYE and is separate from the income tax calculation above.
Should you still reduce your ANI?
If you earn well above £125,140, it may not be practical to reduce your ANI back below £100,000. The pension contributions needed would be very large.
However, there are still reasons to contribute to a pension:
- Tax relief at 45% or 48% is still valuable
- Reducing below £80,000 eliminates the HICBC entirely
- Pension savings compound over time regardless of the tax angle
The key is to be realistic about what threshold you can reach and focus your strategy there.
