At exactly £100,000 your personal allowance is £12,570 — fully intact. But the moment adjusted net income exceeds £100,000, the PA begins tapering at a rate of £1 withdrawn for every £2 of income above the threshold. The effective marginal rate in the taper zone is therefore:
At £100,000, child benefit is 100% clawed back (upper HICBC threshold is £80,000). To recover it, adjusted net income must be reduced below £80,000 — requiring a pension contribution of at least £20,001 at this salary level.
Salary sacrifice pension contributions are extraordinarily efficient at this salary. Each £1 contributed via salary sacrifice saves 40% income tax at the higher rate. But the real power is in protecting the personal allowance: contributions that keep adjusted net income at or below £100,000 avoid the 60% effective rate entirely.
Scenario: bonus of £10,000 received — total income £110,000
PA withdrawn: £5,000 (£1 per £2 above £100k)
Tax on the £10,000 bonus: 40% × £10,000 = £4,000
Tax on the withdrawn £5,000 PA: 40% × £5,000 = £2,000
Total tax on £10,000 bonus: £6,000 — an effective rate of 60%
Solution: salary sacrifice the £10,000 bonus into pension. Tax saved: £6,000. Net pension contribution cost: £4,000.
The annual pension allowance for most people is £60,000 (2026/27). This limits how much you can contribute with tax relief. At £100,000, it's worth confirming whether you've used carry-forward from previous years if you want to make larger contributions.
