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

Salary sacrifice swaps gross pay for a benefit — pension, EV, cycle-to-work — saving you Income Tax and NI. How it works, the limits, and when it backfires.

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.

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 if your adjusted income exceeds £260,000 — reduces your allowance by £1 for every £2 above the threshold, floor £10,000.
  • Money Purchase Annual Allowance (MPAA) is £10,000 for anyone who’s already flexibly drawn DC pension.
  • Lifetime Allowance was abolished from April 2024.

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

Booming scheme post-2022. Your employer leases an electric car through a scheme provider (Octopus, Octopus Electric Vehicles, LeasePlan, etc.) and you sacrifice gross salary equivalent to the lease cost. You get an EV for £200-£500 effective/month when the market lease would be £500-£1,200.

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 tax savings, plus BIK tax = often £300-£500 for a car with £650 list-price lease

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 have higher BIK% (anywhere from 5% to 15%+ depending on electric-only range) and from April 2026 the range test tightened — a hybrid with under 70 miles electric-only range is hit with a step-up in BIK%.

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 12-24 months 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 doesn’t save anything — HMRC taxes you on the higher of the cash equivalent or the BIK value, making sacrifice pointless. EV, pension, cycle-to-work, and childcare were carved out as exceptions.

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 usually lock for 24-36 months. 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.
