At £100,000, you are in the personal allowance taper zone (£100,000–£125,140). Your marginal Income Tax rate is 60% — 40% higher-rate tax plus a further 20% from the PA reduction. Including employee NI (2%), your total marginal rate is 62%. Every extra £1 earned costs you 0.62p in tax.
Should I make a pension contribution on £100,000 to avoid the 60% trap?
Yes — contributing £0 into a pension (SIPP or salary sacrifice) reduces your adjusted net income to £100,000, restoring the full £12,570 personal allowance. This turns a 60% marginal rate on that slice to effectively 0% (the contribution grows tax-free). The tax saving from this pension contribution alone is approximately £0.

The standard personal allowance in 2025-26 is £12,570. At £100,000, your personal allowance is £12,570 (reduced from £12,570 by £0 due to the taper). The taper removes £1 of PA for every £2 earned above £100,000.
