Typical default outputs for quick context.
At exactly £100,000 gross in England for 2026/27, monthly take-home is approximately £5,713 under standard PAYE assumptions (1257L, no student loan, no pension). Income tax is approximately £27,432: 20% on £12,571–£50,270 (£7,540) and 40% on £50,271–£100,000 (£19,892). Employee NI is approximately £4,011: 8% on £12,571–£50,270 (£3,016) and 2% on £50,271–£100,000 (£995). At exactly £100,000, the full personal allowance of £12,570 still applies, the taper begins on income above this threshold.
With a 5% salary sacrifice pension contribution (£5,000/year), monthly take-home falls to approximately £5,471. On Plan 2 student loan, the annual repayment at £100,000 is approximately £6,543 (£545/month), bringing monthly take-home with loan but no pension to approximately £5,168. These figures apply to England; Scotland's advanced rate band (45%) on income from £75,001–£125,140 makes Scottish take-home at £100,000 approximately £5,434/month.
In Scotland at £100,000, the 45% advanced rate applies on income from £75,001, producing a monthly net of approximately £5,434, around £279/month less than England.
Earnings above £100,000 trigger the personal allowance taper: the £12,570 allowance reduces by £1 for every £2 of income above £100,000. By £125,140, the personal allowance is completely withdrawn. This creates an effective 60% marginal rate on the £100,001–£125,140 band, 40% Income Tax on the extra income plus 40% Income Tax on the equivalent personal-allowance income being re-taxed, plus 2% NI. Every £2 of gross income in this band adds only £0.76 to take-home.
A bonus of £10,000 at £100,000 base salary illustrates the impact. In England, that bonus takes gross income to £110,000. The effective combined rate on the bonus is approximately 60% (£6,000 deducted, £4,000 net). The same bonus at £90,000 base would produce approximately £5,800 net, significantly more.
Pension salary sacrifice is the most commonly used tool to manage the taper. A contribution that reduces adjusted net income to £100,000 or below exits the taper entirely. On £105,000 gross, a £5,000 pension contribution restores the full personal allowance and saves approximately £4,800 in extra tax, meaning the £5,000 pension contribution costs only £200 in take-home.
