Salary Sacrifice for Higher-Rate Taxpayers 2026/27

Published by the UK Money Calculators editorial team. Last updated for the 2026/27 tax year.

Higher-rate taxpayers save 42p for every £1 they sacrifice. That is 40% income tax plus 2% employee NI. Basic-rate taxpayers save 28p. The gap is large enough to matter. This guide works through the numbers at £55k, £70k and £100k, and explains the 60% effective rate trap above £100,000.

Why higher-rate taxpayers benefit more

Above the higher-rate threshold of £50,270, income tax jumps to 40%. Employee NI actually drops from 8% to 2% above that same point. But the tax rise more than makes up for it. Net saving per pound of sacrifice above £50,270: 40% + 2% = 42p.

Employer NI stays at 15% throughout. Many employers pass this back as additional pension contributions. That makes the effective return even higher.

Example: £55,000 salary, £3,000 annual sacrifice

At £55,000 you have £4,730 sitting in the higher-rate band. A £3,000 sacrifice sits entirely above £50,270.

• Income tax saving: 40% × £3,000 = £1,200
• Employee NI saving: 2% × £3,000 = £60
• Total personal saving: £1,260 per year
• Net monthly cost of £3,000 pension: £145 per month instead of £250
• Employer NI saving: 15% × £3,000 = £450 per year

If the employer passes back NI in full, the pension gets £3,450 from a sacrifice costing only £1,740 from take-home. That is nearly a 100% uplift.

Example: £70,000 salary, £10,000 annual sacrifice

At £70,000 you are £19,730 above the threshold. All £10,000 falls in the higher-rate band. 40% income tax applies throughout.

• Income tax saving: 40% × £10,000 = £4,000
• Employee NI saving: 2% × £10,000 = £200
• Total personal saving: £4,200 per year
• Net cost of £10,000 pension contribution: £5,800 per year (£483/month)
• Employer NI saving: 15% × £10,000 = £1,500

Post-sacrifice gross salary: £60,000. The pension receives £10,000, or £11,500 if employer NI is passed back. Net take-home cost is £5,800. Every £1 of reduced take-home delivers £1.98 of pension value with NI passthrough.

The £100,000 personal allowance trap, and how sacrifice fixes it

Earn above £100,000 and you start losing your personal allowance. For every £2 above £100,000, £1 of allowance disappears. Between £100,000 and £125,140 the effective marginal tax rate is 60%:

• Every £2 above £100,000 is taxed at 40% directly = £0.80 in tax
• That same £2 causes £1 of personal allowance loss, which costs an additional 40% × £1 = £0.40
• Total tax on that £2: £1.20, i.e. 60% effective rate

Salary sacrifice reduces your adjusted net income. That is the figure HMRC uses for personal allowance tapering. Sacrifice income above £100,000 and you save tax at 60%, not just 40%.

Example: Salary £108,000. Personal allowance is reduced to £12,570 − (£108,000 − £100,000) ÷ 2 = £12,570 − £4,000 = £8,570. Sacrifice £8,000 into pension. New adjusted net income: £100,000. Personal allowance fully restored to £12,570. Tax saving: (1) 60% effective rate on first £8,000 = £4,800 income tax saving, plus (2) 2% NI = £160. Total: £4,960 saved. Net cost of £8,000 pension contribution: £3,040.

Pension annual allowance: check before sacrificing large amounts

The annual allowance is £60,000 for 2026/27. It includes employer contributions and salary sacrifice. A higher earner with a 10% employer contribution on £70,000 (£7,000) who sacrifices a further £25,000 has total inputs of £32,000 — well within the limit. Most employees never get close to £60,000. But if you have large employer contributions or a defined benefit scheme, check before sacrificing big amounts.

The tapered annual allowance applies when threshold income exceeds £200,000 and adjusted income exceeds £260,000. Very few employees hit this. See our annual allowance guide for full details.

30 hours free childcare and child benefit: additional threshold interactions

Two more thresholds are worth knowing about if you have children:

• 30 hours free childcare: requires adjusted net income below £100,000. Sacrificing to stay below this threshold restores access to 30 hours, potentially worth £5,000–£10,000+ per year in childcare savings.
• High Income Child Benefit Charge: claws back 1% of child benefit per £200 of ANI above £60,000. Salary sacrifice reduces ANI, reducing or eliminating the clawback.

For higher earners with children in the £60,000–£125,140 range, the total saving across income tax, NI, childcare costs and child benefit clawback can far exceed the sacrifice amount itself.
