What is my marginal tax rate on £120,000?
At £120,000, 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 70%. Every extra £1 earned costs you 0.70p in tax.
Should I make a pension contribution on £120,000 to avoid the 60% trap?
Yes — contributing £20,000 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 £12,000.
What is the personal allowance at £120,000 in 2025-26?
The standard personal allowance in 2025-26 is £12,570. At £120,000, your personal allowance is £2,570 (reduced from £12,570 by £10000 due to the taper). The taper removes £1 of PA for every £2 earned above £100,000.
What is my monthly take-home on £120,000 in 2025-26?
On a £120,000 salary, your monthly take-home pay in 2025-26 is £6,326. This is after deducting £39,675 Income Tax and £4,411 National Insurance for the year. Your effective tax rate (combined IT + NI as a percentage of gross) is 36.7%. Monthly figures assume equal pay across 12 months with no bonus or variable pay.
How does the £120,000 salary compare to the £100k threshold?
You are £20,000 above the £100,000 threshold where the personal allowance taper begins. To restore your full personal allowance of £12,570 you would need to reduce your adjusted net income to £100,000 — for example via a pension contribution of £20,000. Doing so at your marginal rate of 70% delivers an effective tax saving of approximately £14,000 on that contribution.
