Salary sacrifice on £70,000

## Scenario

An employee earns £70,000 and sacrifices £10,000 into their workplace pension. Their contractual gross pay drops to £60,000. At £70,000 a significant slice of income is already taxed at 40% (the higher rate applies above £50,270). The £10,000 sacrifice is removed from the top of the income, so the entire amount is relieved at 40% for income tax — producing a substantially better effective discount than basic-rate earners receive.

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 | £70,000 | £60,000 | | Taxable pay (gross minus £12,570) | £57,430 | £47,430 | | Basic-rate tax (20% on first £37,700) | £7,540 | £7,540 | | Higher-rate tax (40% on remainder) | £7,892 | £3,892 | | Total income tax | £15,432 | £11,432 | | Employee NI | £3,411 | £3,211 | | Take-home pay | £51,157 | £45,357 | | Pension contribution | £0 | £10,000 |

What the sacrifice actually costs

| | Amount | |---|---| | Take-home reduction | £5,800 | | Pension gained | £10,000 | | Tax saved | £4,000 | | NI saved | £200 | | Total relief | £4,200 | | Effective discount | 42% |

For every £1 sacrificed into pension, take-home falls by only 58p. The 42% effective discount is considerably higher than the 28% available to basic-rate earners, driven almost entirely by the 40% tax saving on the sacrificed slice.

Detailed deduction working

Before sacrifice (gross £70,000): - Taxable pay: £70,000 − £12,570 = £57,430 - Basic-rate tax: £37,700 × 20% = £7,540 - Higher-rate tax: (£57,430 − £37,700) × 40% = £19,730 × 40% = £7,892 - Total tax: £7,540 + £7,892 = £15,432 - NI: (£50,270 − £12,570) × 8% + (£70,000 − £50,270) × 2% = £37,700 × 8% + £19,730 × 2% = £3,016 + £395 = £3,411 - Take-home: £70,000 − £15,432 − £3,411 = £51,157

After 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

Note: the post-sacrifice position (£60,000 gross) matches the pre-sacrifice position in the £60,000 worked example, providing a useful cross-reference.

Student loan interaction (Plan 2)

| | Before sacrifice | After sacrifice | |---|---|---| | Gross pay | £70,000 | £60,000 | | Amount above £27,295 | £42,705 | £32,705 | | Plan 2 repayment (9%) | £3,843 | £2,943 | | Student loan saving | — | £900 |

With the Plan 2 saving included, the net cost is £5,800 − £900 = £4,900, and the effective discount rises to 51% — meaning just under half the gross sacrifice is covered by tax, NI, and loan relief combined.

Employer NI saving

The employer pays NI at 15% on the gross above £5,000. Sacrificing £10,000 removes £10,000 from the employer's NI base, saving the employer £1,500. Employers operating a salary exchange scheme sometimes pass this saving into the employee's pension. If yours does, the pension pot receives £11,500 rather than £10,000 for the same employee take-home reduction of £5,800.

What to notice

• The entire £10,000 sacrifice sits within the higher-rate band before sacrifice. At £70,000, earnings from £50,271 to £70,000 are all taxed at 40%, and the sacrifice removes £10,000 from that portion first. This is why the discount is 42% rather than the 28% seen at basic-rate salaries.
• NI saving is relatively modest (£200) because the 2% rate applies to earnings above £50,270 — much lower than the 8% rate below that threshold.
• Monthly take-home reduction: £483 (£5,800 ÷ 12). Monthly pension contribution: £833. The ratio is strong.
• Post-sacrifice gross remains at £60,000, still within the higher-rate band. A larger sacrifice would continue to attract 40% relief up to £50,270 gross — at which point the rate drops to the basic-rate 28%.
• At £70,000 there is no personal allowance tapering (that begins at £100,000), so there are no complications from the allowance being withdrawn.
• Pension annual allowance: the standard limit is £60,000 (or 100% of earnings, whichever is lower). At £70,000, a £10,000 sacrifice is well within this limit, but if you also receive employer contributions the total should be checked against the allowance.
