Salary Sacrifice Explained: Pension, Cycle to Work & More
Salary sacrifice is an arrangement where you give up part of your gross salary in exchange for a non-cash benefit. Because the sacrifice happens before tax and National Insurance are calculated, you pay less of both — effectively letting the government subsidise the benefit. It is one of the most tax-efficient employee perks available in the UK.
How Salary Sacrifice Works
Instead of receiving your full gross salary and then spending it, you formally agree to a lower salary. Your employer provides the agreed benefit directly. Because your taxable pay is reduced, both income tax and National Insurance are calculated on the lower figure.
Example: You earn £40,000 and sacrifice £3,000 into a pension. Your taxable pay becomes £37,000. You save 20% income tax (£600) plus 8% NI (£240) on the sacrificed amount — a total saving of £840 at zero extra cost to you.
Common Salary Sacrifice Schemes
- Pension contributions: the most common and valuable use — your employer pays contributions directly to your pension before tax
- Cycle to Work: buy a bicycle and safety equipment up to £1,000 (or more with some schemes) through your employer
- Electric Vehicle (EV) lease: salary sacrifice EV schemes have become highly attractive since the benefit-in-kind rate for pure electric cars is just 3% in 2025/26
- Childcare vouchers: legacy scheme closed to new entrants in 2018 but existing members can continue
- Holiday buy: some employers let you sacrifice salary to purchase additional annual leave
- Tech purchases: some employers offer salary sacrifice schemes for laptops, phones and other devices
Pension Salary Sacrifice in Detail
With a salary sacrifice pension, your employer pays contributions to the pension on your behalf. This is different from a standard personal contribution, where you pay from your net pay and the pension scheme claims basic rate tax relief. With salary sacrifice:
- The full contribution goes in gross — no need to claim tax relief separately
- You save NI on the contribution (8% if you earn between £12,570 and £50,270)
- Your employer saves their NI (15%) on the sacrificed amount — some employers pass this saving on to you
- Your adjusted net income is reduced, which can protect your Personal Allowance if you earn near £100,000
If you earn between £100,000 and £125,140, pension salary sacrifice is especially powerful. Each £2 contributed reduces your adjusted net income by £2 and restores £1 of Personal Allowance — creating an effective relief rate of up to 60%.
The Cycle to Work Scheme
Cycle to Work lets you spread the cost of a bike over a hire period (typically 12–18 months) with payments deducted from your gross salary. At the end of the period you can usually buy the bike for a nominal fair market value. Basic rate taxpayers typically save 28–32% of the bike cost; higher rate taxpayers can save up to 42%.
Electric Vehicle Salary Sacrifice
EV salary sacrifice has grown rapidly since the Benefit-in-Kind (BIK) rate on pure electric cars was set at just 2–3%. This means you pay a small amount of tax on the car as a benefit, but sacrifice salary to cover the lease cost. For many higher-rate taxpayers the overall saving versus buying privately or on a personal PCP can be substantial.
Things to Watch Out For
- Minimum wage: your sacrificed salary cannot take your hourly rate below the National Living Wage (£12.21/hour in 2025/26)
- Mortgage and credit impact: lenders assess affordability on your reduced contractual salary, which can affect how much you can borrow
- Statutory pay: Statutory Maternity Pay and Sick Pay are calculated on your reduced salary, which may lower these payments
- Annual allowance: total pension contributions (employer + employee) cannot exceed £60,000 per year without incurring a tax charge
