Salary Sacrifice in 2025-26: Every Benefit You Can Claim Tax-Free

Salary sacrifice is a formal arrangement between you and your employer where you agree to receive a lower salary in exchange for a non-cash benefit. Because your contractual salary is reduced, you pay less income tax and National Insurance on the sacrificed amount. Your employer also saves the employer National Insurance Contributions (NICs) they would otherwise have paid — which many employers pass back to employees as an additional bonus.

How salary sacrifice saves tax

Suppose you earn £50,000 and sacrifice £5,000 for an electric car. Your new contractual salary is £45,000:

• Income tax saving: £5,000 × 40% (higher rate) = £2,000
• Employee NI saving: £5,000 × 2% (on income above £50,270) = £100. But if the sacrifice brings you below £50,270, the saving is at 8%. On £4,730 of the sacrifice: £4,730 × 8% = £378 additional. Total NI saving ≈ £478.
• Employer NI saving: £5,000 × 15% = £750 (which may be shared with you depending on your employer's policy).

Pension salary sacrifice: the most valuable benefit

Pension contributions made via salary sacrifice are the most tax-efficient form of the arrangement because:

• You save income tax at your marginal rate (20%, 40%, or 45%).
• You save employee NICs (8% on earnings between £12,570 and £50,270; 2% above).
• Your employer saves employer NICs at 15% — many employers pass this saving into your pension pot.
• Unlike personal pension contributions, salary sacrifice pension contributions do not show up as income for purposes of the High Income Child Benefit Tax Charge, student loan repayments, or pension annual allowance tapering calculations (because they reduce pensionable pay).

A basic rate taxpayer sacrificing £2,000 saves £400 income tax + £160 NI = £560. A higher rate taxpayer saves £800 tax + £160 NI = £960 on the same £2,000.

Electric vehicles: the most popular benefit in 2025-26

Company car tax (Benefit in Kind, BIK) on electric vehicles is just 2% of list price in 2025-26, rising to 3% in 2026-27 and 4% in 2027-28. This makes EV salary sacrifice extraordinarily tax-efficient for higher earners.

Example: An EV with a list price of £40,000:

• BIK value: £40,000 × 2% = £800
• Higher rate taxpayer's income tax on BIK: £800 × 40% = £320
• If the salary sacrifice is £5,000/year (to cover lease), actual net cost to employee = £5,000 − £2,000 tax saving − £400 NI saving + £320 BIK tax = £2,920 effective cost
• The same car leased personally would cost the full £5,000 after-tax (plus fuel tax, insurance, etc.)

The savings narrow on petrol/diesel cars (BIK rates 15%–37%) — the EV advantage is dramatic by comparison.

Cycle to Work scheme

Under the Cycle to Work scheme, you sacrifice salary to cover the cost of a bike and cycling safety equipment. The government-backed scheme allows:

• Up to £1,000 for a standard bike.
• Up to £2,000 for an e-bike or cargo bike.

At the end of the hire period (typically 12 months), you can purchase the bike at a nominal fair-market value. A basic rate taxpayer sacrificing £1,000 saves approximately £320 in tax and NI — so the bike costs roughly £680 of take-home pay.

Childcare (Tax-Free Childcare) and childcare vouchers

Childcare vouchers under the old employer scheme are closed to new entrants (the Tax-Free Childcare government scheme replaced them). However, employers can still support childcare through salary sacrifice arrangements for nursery fees or workplace nurseries. Tax-Free Childcare itself (HMRC's direct scheme) is separate from salary sacrifice — it works via a government top-up account, not your payroll.

Other benefits available via salary sacrifice

• Annual travel season tickets: Train or bus annual passes — reduces daily commuting costs significantly through tax efficiency.
• Holiday trading: Some employers let you buy or sell annual leave. Buying extra leave via sacrifice reduces taxable salary. Selling leave increases taxable income.
• Gym memberships: Some HMRC-approved workplace gym schemes qualify, though standalone gym memberships are typically a BIK and do not benefit from sacrifice.
• Medical or dental insurance: Premiums paid via sacrifice — though note there is a BIK on private medical insurance, partially offsetting the saving.

National Living Wage restriction

Salary sacrifice cannot reduce your contractual pay below the National Living Wage (NLW) or National Minimum Wage. In 2025-26, the NLW for those aged 21 and over is £12.21 per hour. If you earn close to the NLW, the scope for salary sacrifice may be limited or impossible.

Impact on state benefits and mortgage affordability

Salary sacrifice reduces your contractual salary, which can affect:

• Statutory Maternity/Paternity/Sick Pay: Calculated on contractual salary, which is now lower.
• Mortgage applications: Lenders assess affordability based on gross salary. A lower salary could reduce the amount you can borrow.
• Life and income protection insurance: If linked to a multiple of salary.
• State Pension: If sacrifice reduces earnings below the Lower Earnings Limit (£6,396 in 2025-26), NI credits may be affected.

Frequently asked questions

Can my employer refuse to offer salary sacrifice?

Yes. There is no legal obligation on employers to offer salary sacrifice arrangements, except that they must offer auto-enrolment pension contributions. Whether to offer additional salary sacrifice benefits is entirely at the employer's discretion. If your employer does not offer schemes you want, you can ask HR to consider it — employers benefit from the NI saving, which gives them an incentive to participate.

Is salary sacrifice the same as a pay cut?

Legally, yes — your contractual salary is lower. But the non-cash benefit you receive in exchange has a real value, so in net terms you are typically better off than receiving the full salary and buying the benefit yourself. The key question is whether the benefit is something you would have bought anyway and whether the arrangement is genuinely tax-efficient for your income level.
