Salary Sacrifice: Pension, EV, Cycle (2026/27)

Salary sacrifice is a legal arrangement where you give up part of your cash salary in exchange for a non-cash benefit — most commonly pension contributions, an electric car lease, or a cycle-to-work bike. Because the sacrifice happens before Income Tax and National Insurance are calculated, you save both, and your employer saves employer NI on the sacrificed amount. This guide walks through the three most common schemes and the cases where salary sacrifice genuinely adds value versus cases where it’s marginal or counter-productive.

Why salary sacrifice works

Normal route — you earn £1,000 gross:

• Income Tax 20% = £200
• Employee NI 8% = £80
• Take-home: £720
• You then spend £720 on a bike / pension contribution / whatever

Salary sacrifice route — you sacrifice £1,000 gross:

• Income Tax: not paid on the £1,000 (saved £200)
• Employee NI: not paid on the £1,000 (saved £80)
• Your gross pay is £1,000 lower → your employer receives the benefit value to apply to your pension / car lease / bike
• Net cost to you: £720 effective, same as before
• But you received £1,000 of benefit, not £720

Saving for a basic-rate taxpayer: £280 on every £1,000 sacrificed (28% blended rate). Higher-rate taxpayers save 42% (40% IT + 2% NI above £50,270). Plus your employer saves 15% employer NI (secondary rate from April 2025+), which some employers pass back to you as an enhanced contribution.

The comparison depends on what you would have done instead

Those figures are right when the alternative is spending taxed pay - a bike, a car lease. For a pension they overstate the gain, because an ordinary pension contribution already attracts Income Tax relief without any sacrifice arrangement.

Put £1,000 into a pension the normal way and you pay £800 from net pay; the provider reclaims the £200 basic-rate relief, so £1,000 lands in the pot at a real cost of £800. Sacrifice £1,000 of gross instead and the cost is £720. The gain from sacrificing is £80 - the National Insurance, not the Income Tax.

For a higher-rate taxpayer the incremental gain is smaller still: £1,000 in the pot costs £600 after reclaiming the extra relief through Self Assessment, against £580 by sacrifice. That is £20, the 2% NI above the Upper Earnings Limit.

So for pensions, salary sacrifice is worth the NI - 8% or 2% - plus whatever share of the employer’s 15% your employer passes back, which is often the larger half of the deal. For benefits with no alternative relief, the full 28% or 42% applies.

Pension salary sacrifice

The biggest and most widely-available scheme.

How it works: you agree with your employer to reduce your gross salary by a chosen amount (e.g. 5% or 10%). The employer then pays the sacrificed amount directly into your workplace pension — on top of any “employer contribution” they already make.

Tax treatment: because the contribution happens before PAYE, you pay no Income Tax and no NI on the sacrificed portion. Your payslip shows the reduced gross. You still benefit from long-term investment growth and tax-free growth inside the pension.

Limits to watch:

• Annual Allowance: £60,000 (2026/27, unchanged). Contributions from you, your employer, and any salary sacrifice all count. Go over and you lose tax relief on the excess (Annual Allowance Charge).
• Tapered Annual Allowance applies only if your threshold income is over £200,000 and your adjusted income exceeds £260,000 — it reduces your allowance by £1 for every £2 of adjusted income above £260,000, floor £10,000 (gov.uk). Sacrificed salary counts in adjusted income, so sacrifice does not avoid the taper.
• Money Purchase Annual Allowance (MPAA) is £10,000 for anyone who’s already flexibly drawn DC pension.
• Lifetime Allowance was abolished from April 2024.

NI saving capped from April 2029: HMRC says “From April 2029, only the first £2,000 of employee pension contributions through salary sacrifice each year will be exempt from NICs”, with employee and employer NI due on the excess (policy paper, 26 November 2025; enabling legislation: the National Insurance Contributions (Employer Pensions Contributions) Act 2026). Income Tax relief is unaffected. If you are planning a long run of large sacrifices, the NI part of the gain above £2,000 a year stops from 2029/30.

Side effect — reduced statutory benefits: because your official gross pay is lower, SMP/SSP/mortgage-affordability calculations can be lower too. Some employers “re-gross” for statutory pay purposes; others don’t. Worth asking HR before sacrificing a large percentage.

Electric vehicle (EV) salary sacrifice

Your employer leases an electric car through a scheme provider and you sacrifice gross salary equivalent to the lease cost. Because a fully electric car’s benefit-in-kind charge is low, what the car costs you can be well below the lease price - the worked numbers below show how.

How the numbers work:

• Monthly lease cost (gross) e.g. £600
• You sacrifice £600/month of gross pay
• Income Tax + NI saving at basic rate: ~£168 (28% of £600); at higher rate: ~£252 (42%)
• Benefit-in-kind (BIK) tax applies because you have a company car — currently low for pure EVs but scheduled to rise
• Effective monthly cost: lease cost, minus the tax and NI saved, plus Income Tax on the benefit-in-kind (4% of the car’s list price for a fully electric car in 2026/27)

BIK rates for pure electric cars:

• 2025/26: 3%
• 2026/27: 4%
• 2027/28: 5%
• 2028/29: 7%
• 2029/30: 9%

BIK is (list price) × BIK% × your marginal tax rate. On a £45,000 EV in 2026/27 at 4% BIK and a 40% marginal rate: £45,000 × 4% × 40% = £720/year of BIK tax, or £60/month.

Plug-in hybrids with CO2 emissions of 1-50 g/km pay a BIK% set by their electric-only range: in 2026/27 from 4% (130 miles or more) through 7%, 10% and 14% down to 16% (under 30 miles). The 70-mile boundary between the 7% and 10% bands is long-standing, not a 2026 change. Above 50 g/km the ordinary CO2 bands apply. See the company car tax calculator for your car.

When EV salary sacrifice works: basic-to-higher rate taxpayers, committed to a new car purchase, in a position to sacrifice £300-£1,000/month gross without squeezing cash flow. Works less well for additional-rate taxpayers (BIK tax eats more of the saving) and employees already near minimum wage (sacrifice can’t push gross below NMW).

Cycle-to-work scheme

HMRC-approved, tax-efficient way to get a bike. Same mechanics — employer “buys” the bike, you sacrifice gross salary over the hire period set in your agreement to repay the cost. Savings: 28-42% vs buying outright.

Rules:

• Bike + safety kit must be used primarily for commuting (at least 50% of usage). HMRC doesn’t audit usage but the contract requires the declaration.
• No £1,000 cap since 2019 — scheme operators can finance higher-value bikes/e-bikes/cargo bikes. Some employers still impose internal limits.
• Ownership transfers at end of hire period. HMRC publishes a “Fair Market Value” table (a 3-year-old £2,000 bike costs ~£250 to buy outright at end of scheme).
• You keep the bike even if you leave the employer — the outstanding balance becomes a post-tax deduction from final pay.

Basic-rate taxpayer on a £1,500 e-bike: net cost over 12 months is roughly £90/month (£1,080 total) vs £125/month / £1,500 outright. Saves £420.

Childcare vouchers — closed to new entrants

The old Childcare Voucher salary sacrifice scheme closed to new joiners in October 2018. Existing users can keep using it until their employer stops offering it or their circumstances change. Replacement: Tax-Free Childcare — a direct-to-parent government top-up (up to £2,000/year per child) not routed through employer salary sacrifice.

Schemes that don’t work via salary sacrifice post-2017

The Treasury’s “Optional Remuneration Arrangements” reform (OpRA, April 2017) removed the tax break for a list of benefits even if delivered via salary sacrifice:

• Mobile phones
• Gym membership
• Company car (non-electric, non-low-emission)
• Gadgets / laptops for private use

For these, sacrificing gross salary saves no Income Tax — you are taxed on the higher of the salary given up and the normal benefit-in-kind value (gov.uk: salary sacrifice and the effects on PAYE; for exempt benefits HMRC’s EIM44130 treats “the taxable value of the benefit” as “the amount foregone”). There can still be a National Insurance difference, because the salary given up is no longer cash pay, but the employer then normally owes Class 1A NI on the taxable benefit, so any saving is small and depends on the scheme. Pensions, cycle-to-work, childcare and a few other benefits keep their exemption (EIM44131), and a company car only falls under the higher-of rule if its CO2 figure “exceeds 75 grams per kilometre” (ITEPA 2003 s.120A), which leaves EVs out.

HICBC mitigation angle

Salary sacrifice reduces your adjusted net income, the figure HMRC uses for the High Income Child Benefit Charge. If your salary is £70,000 and you sacrifice £10,000 into pension, your ANI drops to £60,000 — below the HICBC lower threshold, eliminating the charge entirely. See the HICBC guide for worked examples.

Downsides to consider

• Lower gross for mortgage applications — lenders typically use your current gross, not pre-sacrifice. Sacrifice a lot of salary and you borrow less.
• Reduced SMP/SSP base — unless your employer re-grosses for statutory purposes.
• Locked into the lease/contract — EV and cycle schemes lock you in for the agreement term. Job loss mid-scheme can trigger early-termination fees or the outstanding balance becoming due.
• No flexibility mid-year for most schemes. Pension sacrifice can usually be adjusted annually; EV is the full lease term.
