At exactly £100,000, you still have your full personal allowance of £12,570 — the taper begins above this level. But Scotland’s advanced rate (45%) has already been applying since £75,001, adding to a Scotland-vs-England gap that reaches £3,355 per year at £100,000.

England at £100,000: basic rate on £37,700 (£7,540) + higher rate on £49,730 at 40% (£19,892) = £27,432. Scotland applies a 45% advanced rate to £25,000 of earnings that England taxes at 40%, driving the £3,355 gap.
The Personal Allowance Taper — Warning for Earnings Above £100,000
At exactly £100,000, your personal allowance is intact. But earn a single pound more and the taper kicks in. For every £2 you earn above £100,000:
- You lose £1 of personal allowance
- That lost allowance is effectively taxed at double the marginal rate
In Scotland, the effective marginal rate in the taper zone is 67.5%:
- Marginal rate: 45% (advanced rate) on the extra income
- Plus 45% on the lost allowance income — but spread over £2 of earnings
- Combined: 45% + 22.5% = 67.5% effective marginal rate
Compare with England’s taper zone: 40% + 20% = 60% effective marginal rate.
This is why a £100,001 salary in Scotland is worth significantly less than a £100,000 salary once the taper activates.
Pension Strategy at £100,000
| Annual pension contribution | Taxable income | Rate saved |
|---|---|---|
| £10,000 | £90,000 | 45% advanced — £4,500 saved |
| £20,000 | £80,000 | 45% advanced — £9,000 saved |
| £25,000 | £75,000 | All advanced rate removed |
Salary sacrifice above £100,000 also slows the PA taper — a £1,000 contribution cuts income to £99,000, preserving the full allowance and removing both the advanced rate and taper exposure. This is one of the highest-efficiency uses of pension saving in the UK tax system.
Worked Example — David, IT Director in Aberdeen
David earns £100,000 as IT director at an energy company in Aberdeen. Monthly:
- Gross: £8,333
- Scottish income tax: £2,566 (S1257L)
- Employee NI: £334
- Pension (5%): £417
- Net pay: £5,016
He contributes £25,000/year into a SIPP (self-invested personal pension) via annual bonus, bringing his taxable income to £75,000. This saves £11,250 in advanced rate tax and keeps him below the taper threshold — saving an estimated additional £2,531 in income tax that would otherwise apply if the PA eroded.
