UK Salary Sacrifice 2025/26: Pension vs EV vs Bike Comparison
Salary sacrifice cuts your taxable pay and adds employer NI savings. Pension, EV lease and Cycle to Work each have different mechanics — at £60k a year, a £400/month EV lease costs as little as £232 net; a £6,000 pension sacrifice costs £3,480.
How salary sacrifice works
Salary sacrifice (sometimes "salary exchange") is a contractual variation of your employment: you agree to receive lower gross salary in return for a non-cash benefit of equivalent value. Because the benefit is non-cash, it is exempt from one or both of:
- Income tax — depends on benefit type.
- Employee National Insurance — almost always exempt.
- Employer National Insurance — exempt, so the employer also saves 15%.
HMRC's EIM42750 confirms the mechanics. The variation must be a real contractual change made before the salary is earned — you can't retrospectively reclassify pay.

Open Salary Sacrifice calculatorThe three flagship schemes compared (£60,000 earner)
Take a higher-rate taxpayer on £60,000. Their marginal rate is 42% (40% tax + 2% NI) on the £9,730 above £50,270, and 28% (20% + 8%) on the slice below.
Scheme 1 — Pension salary sacrifice (£6,000/year)
| Item | Amount |
|---|---|
| Gross sacrificed | £6,000 |
| Tax saved (£6,000 × 42% blended) | £2,520 |
| Net pay cost | £3,480 |
| Employer NI saved (15%) | £900 |
| If employer adds employer-NI saving | £6,900 into pension |
| Effective relief | Up to 49% |
Pension is the most powerful option because contributions reduce both taxable income and threshold income for the pension taper, and most employers add employer-NI savings.
Scheme 2 — EV salary sacrifice (£500/month lease = £6,000/year)
| Item | Amount |
|---|---|
| Gross sacrificed | £6,000 |
| Tax + NI saved (blended 42%) | £2,520 |
| BIK on £40,000 EV at 3% | £1,200 |
| BIK income tax @ 40% | £480 |
| Net pay cost | £3,960 |
So a headline £6,000 lease costs £3,960 net — about a third off the sticker price. Compared with a personal contract hire equivalent, EV sacrifice is typically 30–40% cheaper all-in. See our EV salary sacrifice case study.
Scheme 3 — Cycle to Work (£1,200 bike + £200 accessories)
| Item | Amount |
|---|---|
| Gross sacrificed (12 months) | £1,400 |
| Tax + NI saved (42% blended) | £588 |
| Net cost | £812 |
| Final value at end of hire | ~£100 |
| Final transfer-of-ownership fee | £100 |
| All-in cost | £912 |
A £1,400 bike for £912 — 35% effective discount. Below the threshold for FCA-regulated credit if under £1,000; above, the employer needs FCA permission (most major scheme providers cover this).
Comparison table
| Scheme | Basic-rate saving | Higher-rate saving | Additional-rate saving | Catches |
|---|---|---|---|---|
| Pension | 28% | 42% | 47% | AA £60k cap; taper above £260k |
| EV | 28% minus 0.6% BIK | 42% minus 1.2% BIK | 47% minus 1.35% BIK | Lock-in 24–48 months |
| Cycle to Work | 28% | 42% | 47% | Bike usually £1k cap; ToO fee at end |
(BIK figures: 3% × marginal tax rate.)

Maria, £35,000 salary, sacrifices: 5% pension (£1,750), £1,200 bike, no EV.
- Total sacrifice: £2,950.
- Tax + NI saved: £2,950 × 28% = £826.
- Net pay cost: £2,124.
- Employer NI saved: £442.50.
- Pension uplift: typically 3% employer match (£1,050 extra) → pension gets £2,800; bike costs £576 net.
- Combined benefit per £1 of sacrifice: ~£1.30.

Salary sacrifice calculatorWorked example — £125k higher-rate maxed sacrifice
Tom, £125,000 (just below the 60% taper at £100–£125k), sacrifices: £25,000 pension + £500/month EV.
| Item | Amount |
|---|---|
| Gross sacrificed | £31,000 |
| Adjusted net income | £94,000 (below £100k taper) |
| Income tax saved (band-specific) | £12,420 |
| NI saved | £620 |
| BIK at 3% on £45k EV | £1,350 |
| BIK income tax @ 40% | £540 |
| Net pay cost | £17,500 |
| Employer NI saved | £4,650 |
| If employer reinvests: pension uplift | up to £29,650 |
Tom escapes the 100k personal-allowance taper entirely by sacrificing under £100k of adjusted net income. The £2,514 of restored personal allowance saves another £1,005 of tax.
Things to watch
1. National Living Wage floor
NLW 2025/26 is £12.21/hour. Post-sacrifice pay cannot drop below this. For a 37.5-hour week, the floor is £23,809.50. Anyone close to that limit cannot sacrifice freely.
2. Mortgage applications
Lenders typically use post-sacrifice salary. Some gross up pension; few gross up EV/bike. Pause major sacrifice in the 3–6 months before a mortgage application.
3. Statutory benefits
Sacrificed pay below the LEL (£6,500) loses NI qualifying year. Statutory Maternity Pay, SSP and redundancy are based on post-sacrifice earnings, so heavy sacrifice may cut these.
4. Lifestyle creep on EV
A 36-month EV lease is a real commitment. If you leave the employer mid-lease, you either continue paying personally or pay an early-termination fee (often 3–6 months of payments).
5. Bike scheme final transfer
The "ownership transfer" fee at end of a 12-month bike hire is set by HMRC's table — typically 18–25% of original cost for a £1,000+ bike. Extended-hire schemes (4 years) cut this to ~3%. See Cycle to Work 2025/26.
Which to pick?
Pension first. Always. Highest relief, no lock-in beyond the 55/57 access age, and reduces every income-related tax trap (HICBC, 100k taper, pension taper).
EV second — only if you genuinely need a car and have a stable employer. Effective price is materially below retail, but it's a 36–48-month commitment.
Cycle to Work third — a low-stakes, high-saving way to get a new commute bike. Genuinely 30%+ off, with little downside.
Many higher-rate earners run all three at once plus a modest ISA contribution — a tax-efficient stack.

Frequently asked questions
Which salary sacrifice scheme saves the most tax?
It depends on tax band. For a basic-rate payer all three schemes save 28% (20% tax + 8% NI). For a higher-rate payer, pension and Cycle to Work save 42% (40% + 2%); EV salary sacrifice saves a smaller 42% on the lease minus the BIK charge (3% in 2025/26).
Is there a cap on salary sacrifice in 2025/26?
Pensions: capped by the £60,000 annual allowance (tapered for high earners). Cycle to Work: typically £1,000 but employers can permit higher with FCA-authorised credit. EV salary sacrifice: no cap, but post-sacrifice pay must not fall below the National Living Wage.
Does salary sacrifice affect mortgage borrowing?
Yes — lenders use post-sacrifice salary by default. Some lenders gross up pension contributions; few gross up EV or bike sacrifice. If applying for a mortgage, request a P60 plus a salary sacrifice schedule and ask the lender to consider gross pay.
Does salary sacrifice reduce my State Pension?
Sacrifice reduces National Insurance contributions, but as long as your post-sacrifice earnings exceed the Lower Earnings Limit (£6,500 in 2025/26), the year still counts as a qualifying NI year. State Pension entitlement is unaffected.
What is the BIK rate on an EV in 2025/26?
3% of P11D list price — rising 1pp per year to 5% in 2027/28. For a £40,000 EV, BIK is £1,200/year, taxed at marginal rate (20% = £240, 40% = £480).
