How salary sacrifice works on a £20,000 salary

With a £20,000 gross salary, a £1,000 pension sacrifice reduces your taxable salary to £19,000. You pay income tax and National Insurance on the lower figure, not the original £20,000.

At £20,000, your salary sits within the basic-rate (20%) income tax band. Each £1,000 sacrificed saves £200 in income tax, plus £80 in employee NI (at the 8% rate below £50,270) — a combined saving of £280 per £1,000 sacrificed.

The £1,000 goes into your pension. You receive the full £1,000 pension contribution, but your take-home pay only falls by £720 per year (£60/month) — the difference is the tax and NI you no longer pay.
