Salary Sacrifice Cap Rules UK 2026/27: What's Allowed

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.

Quick reference: what works, what doesn't

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:
  1. The cash salary you gave up (the sacrifice amount), or
  2. 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:

1. Pension contributions - the headline use case. Full tax + NI saving on the sacrificed amount.
2. Pensions advice (up to £500/year) - employer-funded financial advice on workplace pensions.
3. Cycle to Work scheme - bicycle and safety equipment under the s244 ITEPA exemption. There is no cap on the value (see below).
4. Ultra-low emission vehicles (ULEV) - company cars under 75g/km CO₂. The BIK is already low in 2026/27: 4% for a fully electric car, 4% to 16% for a plug-in hybrid depending on its electric range, and 17% to 21% from 51 to 74g/km.
5. Childcare vouchers for employees who joined a scheme before 5 October 2018 and have remained continuously enrolled.
6. Workplace nurseries - direct-cost nurseries provided at the workplace.

The NMW floor, and which pay it is tested on

The rule that bites lower-paid workers is that a salary sacrifice cannot take you below the National Minimum Wage - and the test is on what is left after the sacrifice, not on what you earned before it.

That is the whole point of a sacrifice: you give up the contractual entitlement, so the pay is gone for minimum wage purposes too. HMRC's own manual puts it plainly: "Where a salary sacrifice is in place, the worker no longer has entitlement to that amount of pay under their contract. Therefore, their pay for minimum wage purposes is reduced accordingly." Testing the pre-sacrifice figure would mean no sacrifice could ever breach NMW, which is the opposite of the rule.

This is not a new rule and there is no date at which it started applying; it follows from how the National Minimum Wage Regulations 2015 define the pay that counts. Nor is there any mechanism that reverses a sacrifice after the event. GOV.UK puts the duty on the employer, in advance: "A salary sacrifice arrangement must not reduce an employee's cash earnings below the National Minimum Wage rates. Employers must put procedures in place to cap salary sacrifice deduction and ensure NMW rates are maintained."

Practical effect: if your contractual rate is £13.50 an hour and the 2026/27 National Living Wage is £12.71, the most you can sacrifice is the 79p an hour of headroom between them. A scheme that would take you past that has to be capped before it runs, and if it was not, you have an underpayment of the minimum wage rather than an automatic refund.

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 on pay after sacrifice (see above).
• Pension Annual Allowance (£60,000/year, tapered by £1 for every £2 of adjusted income above £260,000, bottoming out at £10,000 once adjusted income reaches £360,000 - see the annual allowance guide).
• Pension Lifetime Allowance - abolished from April 2024, replaced with the Lump Sum Allowance + Lump Sum and Death Benefit Allowance.
• Cycle scheme - none. The £1,000 figure you will see quoted is not a tax limit (see below).

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 4% 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

A £1,000 bike saves around £400 at basic rate and £600 at higher rate. A more expensive bike saves proportionately more, because there is no ceiling on the relief.

The £1,000 is not a tax cap, and there is no e-bike limit. The Department for Transport's own scheme guidance is explicit at paragraph 4.7: "For tax and National Insurance purposes there is no limit on the value of the cycle and safety equipment you can provide to an employee." What £1,000 actually marks is a consumer-credit threshold. Under the Financial Services and Markets Act 2000 (Exemption) Order 2001 an employer that owns the goods does not need FCA authorisation where the total value hired is £1,000 or less. Above that, paragraph 5.5 says schemes "are acceptable provided the requisite FCA authorisation is obtained" - and the same is true at any value where the agreement is with a third-party scheme provider rather than the employer. No figure of £3,500 appears anywhere in that guidance, for e-bikes or anything else, and there is no lifetime cap per employer.

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

1. 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.
2. Confirm the benefit is in the protected list (or accept that for non-protected benefits, you'll pay BIK on the sacrificed amount).
3. Check NMW / NLW won't be breached post-sacrifice.
4. Confirm the employer is offering it under their formal scheme, not informally. Informal "deductions" don't qualify for tax + NI relief.
5. 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.
