Salary Sacrifice Worked Examples 2026/27: £30k, £40k, £50k Salaries

Exact salary sacrifice calculations for 2026/27 at three salary levels: £30,000, £40,000 and £50,000. See the income tax saving, NI saving, employer NI saving and net take-home cost for each.

How to read these examples

All examples use England/Wales/Northern Ireland income tax rates for 2026/27. The personal allowance is £12,570. Income tax rates: 20% basic rate on £12,571–£50,270; 40% higher rate on £50,271–£125,140. Employee NI: 8% on £12,570–£50,270; 2% above that. Employer NI: 15% on all earnings above £5,000.

Each example shows a 5% pension sacrifice, a common starting point for employee pension contributions. Substitute your own sacrifice amount proportionally if needed. All figures are annual unless stated. 'Net cost' means the reduction in take-home pay after allowing for income tax and NI savings. The pension contribution itself is shown as gross, the amount that goes into the pension.

£30,000 salary, 5% sacrifice (£1,500 per year)

Gross salary: £30,000. Annual sacrifice: £1,500 (5%). Post-sacrifice gross for PAYE: £28,500. All the sacrifice sits in the basic-rate income tax band and the main employee NI band.

Income tax saving: £1,500 × 20% = £300. Employee NI saving: £1,500 × 8% = £120. Total personal saving: £420 per year, or £35 per month. Net take-home cost of the £1,500 pension contribution: £1,080 per year (£90 per month). Without sacrifice, the same £1,500 contribution under relief at source would cost only £300 in tax relief, the employee still pays NI on the full £30,000. The sacrifice route saves an extra £120 per year (the NI saving). Employer NI saving: £1,500 × 15% = £225 per year.

£40,000 salary, 5% sacrifice (£2,000 per year)

Gross salary: £40,000. Annual sacrifice: £2,000 (5%). Post-sacrifice gross: £38,000. All the sacrifice sits in the basic-rate and main NI band (well below the £50,270 threshold).

Income tax saving: £2,000 × 20% = £400. Employee NI saving: £2,000 × 8% = £160. Total personal saving: £560 per year, or £46.67 per month. Net cost of the £2,000 pension contribution: £1,440 per year (£120 per month). In other words, you put £167 per month into your pension and only feel £120 less in your pay packet. The employer saves 15% × £2,000 = £300 per year in NI, which if passed back in full takes the total pension input to £2,300 at a net cost to you of just £1,440.

£50,000 salary, 5% sacrifice (£2,500 per year)

Gross salary: £50,000. Annual sacrifice: £2,500 (5%). Post-sacrifice gross: £47,500. Note: the original salary of £50,000 is below the higher-rate threshold of £50,270, so all of the sacrifice sits in the basic-rate band. The saving is: income tax 20% × £2,500 = £500; NI 8% × £2,500 = £200; total £700 per year, or £58.33 per month. Net cost: £1,800 per year (£150 per month). Employer NI saving: £375.

Now consider a £52,000 salary with a £2,600 sacrifice (5%). The sacrifice spans the higher-rate threshold. The first £1,730 of sacrifice (from £52,000 down to £50,270) saves 40% tax + 2% NI = 42%. The remaining £870 (from £50,270 down to £49,400) saves 20% tax + 8% NI = 28%. Blended saving: (£1,730 × 0.42) + (£870 × 0.28) = £726.60 + £243.60 = £970.20. Net cost: £1,629.80 per year (£135.82 per month), noticeably less than the lower-salary example, because more of the sacrifice falls in the higher-rate band.

Bonus sacrifice: the additional higher-rate saving

Bonus sacrifice follows the same rules but may save more because bonuses are often taxed at the higher rate. If you earn £45,000 basic and receive a £5,000 bonus, the first £5,270 of the bonus (from £45,000 to £50,270) is taxed at 20% and NI at 8%, while the remaining £4,730 (above £50,270) is taxed at 40% and NI at 2%. Sacrificing the full £5,000 bonus before it is paid into the basic-rate portion saves 28p per pound (£1,400 total); the portion in the higher-rate band saves 42p per pound.

The timing rule for bonus sacrifice is critical: the election to sacrifice must be made before the bonus is declared as payable, not after. HMRC will not allow retrospective sacrifice after the employee has gained a right to the cash. Confirm the timing with HR before relying on this planning.
