Salary sacrifice - where you give up part of your gross salary in exchange for a non-cash benefit - has been one of the UK's most powerful tax-and-NI optimisation tools for decades. The 2017 Optional Remuneration Arrangements (OpRA) rules narrowed the field substantially, and further changes have phased in through 2024-2026. This guide covers what's still allowed, what's now blocked, and where the smart money goes.

How salary sacrifice works (quick recap)
You agree contractually to reduce your gross salary by £X per year. In exchange, your employer provides a non-cash benefit worth £X. The mechanics:
- Your gross salary is permanently reduced (NOT a deduction from net pay).
- Your employer pays you less in cash but provides the benefit instead.
- Income tax + employee NI are calculated on the reduced gross.
- Employer NI is also reduced (employer saves 15% on the sacrificed amount in 2026/27).
A £6,000/year pension salary sacrifice for a basic-rate taxpayer typically saves:
- Income tax: £1,200 (20% × £6,000)
- Employee NI: £480 (8% × £6,000)
- Total your saving: £1,680/year
- Employer NI saving: £900 (15% × £6,000) - sometimes shared with you as additional pension contribution
The OpRA rules - what changed in 2017
Before April 2017, almost any non-cash benefit qualified for full tax + NI savings via salary sacrifice. The Optional Remuneration Arrangements rules introduced from 6 April 2017 restricted this to a narrow protected list.
Under OpRA, for non-protected benefits:
- The taxable amount is the higher of:
- The cash salary you gave up (the sacrifice amount), or
- The standard benefit-in-kind value.
This means for most benefits, you pay tax/NI on the cash you sacrificed, killing the benefit's tax efficiency.
What OpRA preserved (still tax-efficient)
The 2017 rules carved out specific protected benefits. As of 2026/27, the protected list is:
- Pension contributions - the headline use case. Full tax + NI saving on the sacrificed amount.
- Pensions advice (up to £500/year) - employer-funded financial advice on workplace pensions.
- Cycle to Work scheme - bicycle + safety equipment under HMRC's tax-free cycle scheme (£1,000 standard, £3,500 e-bikes).
- Ultra-low emission vehicles (ULEV) - company cars under 75g/km CO₂. The BIK is already low (1-14% in 2026/27 depending on the model and electric range).
- Childcare vouchers for employees who joined a scheme before 5 October 2018 and have remained continuously enrolled.
- Workplace nurseries - direct-cost nurseries provided at the workplace.
The 2024 hospitality / NMW twist
A subtle but important change: from April 2025, salary sacrifice arrangements that drop an employee's "pre-sacrifice" cash earnings below the National Minimum Wage are invalid. This affects lower-earning workers in pension schemes most.
Practical effect: if your hourly rate before sacrifice is £12.50 and your sacrifice would drop your effective hourly rate below £12.21 (the 2026/27 NLW), the sacrifice is rolled back automatically.
The £6,500 NI saving threshold (mythbuster)
You'll see references online to "the £6,500 salary sacrifice cap" or "the NI saving cap". This is a misconception. There is no per-person annual cap on salary sacrifice itself.
The £6,500 figure appears to come from confused references to the Annual Allowance for pension contributions (£60,000 in 2026/27, not £6,500). Pension salary sacrifice combined with employer contributions is capped at £60,000 per year - well above what most employees would sacrifice.
For practical purposes, the only hard limits are:
- NMW floor (per the 2025 rule above).
- Pension Annual Allowance (£60,000/year, with a tapered allowance from £260k income down to £10k from £312k income).
- Pension Lifetime Allowance - abolished from April 2024, replaced with the Lump Sum Allowance + Lump Sum and Death Benefit Allowance.
- Cycle scheme - £1,000 (£3,500 e-bikes) per scheme, lifetime limit per employer.
Where the smart money is going (2026/27)
Three sacrifice strategies are still highly tax-efficient for typical employees:
1. Maximum pension salary sacrifice up to the Annual Allowance
Especially valuable if you're in the £100k-£125k Personal Allowance taper zone (62% effective marginal rate kept). A £25,000 pension sacrifice at this income range saves ~£15,500/year in tax and NI.
See our salary sacrifice deep dive for the full mechanics.
2. ULEV company car
A pure electric company car at 2% BIK in 2026/27 vs paying for the same car personally creates a saving of £3,000-£8,000/year for higher-rate taxpayers. The car must be a genuine company car (not a leaseback arrangement).
3. Cycle to Work for daily-commuter purchase
For workers commuting by bike, the £1,000 cap (£3,500 e-bikes) saves around £400 (basic rate) to £600 (higher rate) on a £1,000 bike purchase.
Where salary sacrifice no longer works
These are common questions where the answer is now "no" since OpRA:
- Health insurance: No tax saving - the OpRA higher-of rule applies.
- Gym memberships: No tax saving for the same reason.
- Smartphone (second device, or for personal use): One employer-provided phone is exempt; a second is not.
- Holidays: Adding extra holiday days via sacrifice creates taxable benefit equal to the cash sacrificed.
- Personal accommodation rent: Tax-effective only if the housing is "necessary for the proper performance of duties" (specific job-related accommodation - caretaker, vicar, lighthouse keeper).
How to set up salary sacrifice properly
- Get the contract change in writing. A salary sacrifice that's just a payroll deduction isn't legally a sacrifice - HMRC requires a permanent contractual change to your salary.
- Confirm the benefit is in the protected list (or accept that for non-protected benefits, you'll pay BIK on the sacrificed amount).
- Check NMW / NLW won't be breached post-sacrifice.
- Confirm the employer is offering it under their formal scheme, not informally. Informal "deductions" don't qualify for tax + NI relief.
- Lifestyle change clause: most schemes allow you to opt out at major life events (marriage, divorce, parental leave, redundancy). Verify this is in your scheme T&Cs.
Salary sacrifice on your payslip
A correctly-applied salary sacrifice should show:
- Reduced gross salary as the headline figure (not the pre-sacrifice number).
- No "salary sacrifice" deduction line under deductions - the gross is already reduced.
- Pension contribution line showing 0% if the sacrifice is going to pension (because it's not a deduction; it's part of the reduced gross flowing direct to pension).
If your payslip shows a "salary sacrifice" deduction in the deductions column, your scheme is set up incorrectly - talk to payroll.
