Example
Salary sacrifice on GBP 60,000
A worked example showing why salary sacrifice becomes a more strategic pay-planning choice once taxable pay is comfortably above mid-range salary levels.
## Scenario
An employee earns £60,000 and sacrifices £10,000 into their workplace pension. Their contractual gross pay drops to £50,000. This is a higher-rate taxpayer before the sacrifice: at £60,000, earnings above £50,270 are taxed at 40%. The sacrifice removes £10,000 from the top of the income — which means the relief is calculated partly at 40% rather than 20%, making the effective discount substantially higher than at basic-rate salaries.
All figures use 2025-26 rates: personal allowance £12,570, basic rate 20% up to £50,270 gross, higher rate 40% above £50,270, employee NI 8% between £12,570 and £50,270, 2% above £50,270.
Before and after comparison
| | Before sacrifice | After sacrifice | |---|---|---| | Gross pay | £60,000 | £50,000 | | Taxable pay (gross minus £12,570) | £47,430 | £37,430 | | Basic-rate tax (20% on first £37,700) | £7,540 | £7,486 | | Higher-rate tax (40% on remainder) | £3,892 | £0 | | Total income tax | £11,432 | £7,486 | | Employee NI | £3,211 | £2,994 | | Take-home pay | £45,357 | £39,520 | | Pension contribution | £0 | £10,000 |
What the sacrifice actually costs
| | Amount | |---|---| | Take-home reduction | £5,837 | | Pension gained | £10,000 | | Tax saved | £3,946 | | NI saved | £217 | | Total relief | £4,163 | | Effective discount | 41.6% |
The higher effective discount compared to basic-rate examples (28%) comes from the higher-rate tax saving. The top £9,730 of the sacrifice (the slice from £50,270 down to £50,000 of post-sacrifice gross, plus the £9,730 above £50,270 before sacrifice) is relieved at 40%.
Detailed deduction working
Before sacrifice (gross £60,000): - Taxable pay: £60,000 − £12,570 = £47,430 - Basic-rate tax: £37,700 × 20% = £7,540 - Higher-rate tax: (£47,430 − £37,700) × 40% = £9,730 × 40% = £3,892 - Total tax: £7,540 + £3,892 = £11,432 - NI: (£50,270 − £12,570) × 8% + (£60,000 − £50,270) × 2% = £37,700 × 8% + £9,730 × 2% = £3,016 + £195 = £3,211 - Take-home: £60,000 − £11,432 − £3,211 = £45,357
After sacrifice (gross £50,000): - Taxable pay: £50,000 − £12,570 = £37,430 - Tax: £37,430 × 20% = £7,486 (all within basic-rate band; the higher-rate band is not reached) - NI: (£50,000 − £12,570) × 8% = £37,430 × 8% = £2,994 (no 2% upper-rate NI because gross is below £50,270) - Take-home: £50,000 − £7,486 − £2,994 = £39,520
Student loan interaction (Plan 2)
| | Before sacrifice | After sacrifice | |---|---|---| | Gross pay | £60,000 | £50,000 | | Amount above £27,295 | £32,705 | £22,705 | | Plan 2 repayment (9%) | £2,943 | £2,043 | | Student loan saving | — | £900 |
If the employee also holds a Plan 2 loan, the annual take-home reduction shrinks further: £5,837 − £900 = £4,937. The effective discount rises to roughly 50.6% — meaning barely half the gross sacrifice leaves the employee's pocket.
Employer NI saving
At £60,000 the employer pays NI at 15% on the gross above the secondary threshold (£5,000 for 2025-26). Sacrificing £10,000 removes £10,000 from the employer's NI base, saving the employer £1,500. Some employers pass this saving back into the employee's pension. If yours does, the pension contribution is £11,500 rather than £10,000, making the arrangement even more valuable. Check your employer's scheme rules.
What to notice
- The key difference at £60,000 is that the sacrifice pulls income from the 40% band into the 20% band. That alone accounts for £3,892 of the £4,163 total relief.
- NI saving is relatively small (£217) because at this salary the NI uplift rate of 2% above £50,270 is much lower than the 8% that applies below that threshold.
- After sacrifice, gross pay is £50,000 — just below the higher-rate threshold. All taxable income is therefore at 20%, giving a clean position with no higher-rate exposure.
- Monthly take-home reduction is £486 (£5,837 ÷ 12). For a pension contribution of £833 per month, that is a cost-effective ratio.
- The sacrifice does not affect the personal allowance; tapering only begins above £100,000.
