What Is Salary Sacrifice? A Plain-English UK Guide for 2026/27
What is salary sacrifice?
Salary sacrifice is an agreement between you and your employer to reduce your gross cash pay in return for a non-cash benefit of equivalent value. HMRC's technical guidance puts it simply: "a salary sacrifice happens when an employee gives up the right to part of the cash remuneration due under his or her contract of employment". The reduction is built into your employment contract before tax is calculated, so the salary you sacrifice never appears in your taxable income.
Because the benefit is paid from gross pay rather than from net take-home, you avoid the Income Tax and employee National Insurance you would have paid on that slice of salary. Your employer also pays less Class 1 secondary National Insurance, currently 15% in 2026/27, on the lower salary. The result is a benefit that costs you noticeably less than buying the same thing out of your post-tax wages.
A note on terminology. HMRC's official documents use the phrase "salary sacrifice arrangement". In everyday use, and throughout this guide, it is called a salary sacrifice scheme. The two terms mean the same thing.
How salary sacrifice works (the tax mechanics)
Three things change when you enter a salary sacrifice scheme. First, your gross salary is reduced by the agreed amount. Second, you receive a non-cash benefit of equivalent value, paid for by your employer out of the salary you gave up. Third, all PAYE calculations (Income Tax, employee National Insurance, employer National Insurance) are run against the new, lower salary figure.
For most benefits, HMRC requires the employer to value the benefit by the higher of the salary given up or the normal benefit-in-kind earnings charge. There are deliberate carve-outs for benefits the government wants to encourage: payments into a registered pension scheme, employer-provided pensions advice, workplace nurseries, cycle-to-work bicycles and safety equipment, and ultra-low-emission cars (which are still benefit-in-kind taxable, but at concessional rates).
A salary sacrifice scheme only works if it is a genuine change to your contract. HMRC sets out the conditions in EIM42750 and the supporting pages of its Employment Income Manual: there must be a written variation to your terms, the change must apply prospectively (you cannot retrospectively reclassify pay already earned), and you cannot simply swap benefits back to cash whenever you choose. Where employers get this wrong, HMRC can deny the tax advantages and recover the tax and NIC the employee and employer would otherwise have paid. The full mechanics are explained on HMRC's main employer guide, Salary sacrifice for employers, which covers PAYE reporting, contract variation and pension treatment.
What can you salary sacrifice in the UK?
There is no single official list, but in practice UK employers offer salary sacrifice on a handful of well-established benefits. They sit in roughly this order of popularity.
Pensions
Pension contributions are the most widespread use of salary sacrifice in the UK and the one HMRC treats most generously. When you sacrifice salary into your workplace pension, the contribution is paid by the employer directly into your registered pension scheme. There is no Income Tax to reclaim, no National Insurance for either you or your employer to pay on the sacrificed amount, and many employers pass their NIC saving back into the pension as an additional contribution. For more on how this stacks up against personal pension contributions, see salary sacrifice vs deduction and our dedicated guide to salary sacrifice for pensions. HMRC's annual allowance currently lets most people contribute up to £60,000 per year across all pension inputs before a tax charge applies.
Cycle to work
The cycle-to-work scheme lets you sacrifice salary in exchange for a bike and safety equipment, hired from your employer over an agreed period (usually 12 to 48 months). It is one of the carve-outs HMRC excludes from the wider 2017 optional remuneration rules, so the full Income Tax and National Insurance relief still applies. Most schemes give an end-of-term option to acquire the bike for a small market value payment.
Workplace nurseries and childcare
Workplace nurseries provided by an employer, or directly contracted childcare in place before 4 October 2018, can still be offered through salary sacrifice with full Income Tax and NIC exemption. Newer childcare voucher schemes are closed to new joiners. Employees starting after that date use the government's Tax-Free Childcare scheme instead.
Employer-provided technology
Some employers offer salary sacrifice on computers, mobiles and other home-office equipment. There is no headline tax exemption here, so the value of the kit counts as a benefit in kind under the normal rules. The saving is usually modest, comprising the employer NIC saving and any procurement discount the employer can pass on, but it is a useful way for staff to spread the cost.
Electric cars
Ultra-low-emission cars (pure electric and the lowest-CO2 plug-in hybrids) are taxed at preferential Benefit-in-Kind rates. For pure EVs in the 2026/27 tax year, the BiK rate is 4%. That is why EV salary sacrifice has grown so quickly: the BiK charge is so small that the Income Tax and NIC savings on the sacrificed salary comfortably outweigh it. We cover that in the dedicated section below.
Other less common uses
Less commonly, employers will run salary sacrifice on additional holiday days, gym membership, charitable giving (where the GAYE scheme is more usual), or pensions advice. These benefits do not always carry a tax advantage. Many are taxed in full as a benefit in kind, so the saving comes mainly from the employer NIC reduction and the convenience of a single payroll deduction.
How much can you actually save?
For most employees, the headline number is between 20% and 50% of the cost of the benefit. Where you sit in that range depends on your marginal Income Tax rate and whether the benefit attracts a residual benefit-in-kind charge.
A basic-rate taxpayer saves 20% Income Tax plus 8% employee National Insurance on the sacrificed amount, totalling 28% of the gross sacrifice before any employer NIC contribution is passed back. A higher-rate taxpayer saves 40% Income Tax plus 2% NIC on earnings above the upper earnings limit (£50,270 in 2026/27), closer to 42%. An additional-rate taxpayer, on earnings above £125,140, saves 45% Income Tax plus 2% NIC. Where the employer rebates its 15% Class 1 secondary NIC saving back into the benefit (common with pensions), employee-side economics improve further.
Any provider quoting savings above 50% on a normal salary sacrifice scheme is rolling the employer's National Insurance saving into the employee's headline figure. They are not the same money. The employee saves what the employee saves; the employer's NIC reduction sits on the employer's books unless it is explicitly passed back.
The rules and the caveats
Salary sacrifice is straightforward when run properly, but it is genuinely a change to your contract of employment and there are a few things to check before signing.
National Minimum Wage
The single hard limit is the National Minimum Wage. Your gross cash pay after the sacrifice cannot fall below the National Minimum Wage in force at the time for your age band. HMRC requires employers to put procedures in place to cap deductions and protect NMW, and a scheme that breaches NMW is not a valid salary sacrifice. This is the most common reason employees on lower salaries are excluded from a scheme.
State benefits and statutory pay
Because salary sacrifice reduces the cash earnings on which National Insurance is charged, it can reduce or remove entitlement to earnings-related and contribution-based benefits. The benefits most often affected are Maternity Allowance, Additional State Pension, Incapacity Benefit and the contribution record for the State Pension. Statutory payments (Statutory Maternity, Paternity, Adoption and Sick Pay) are calculated from average weekly earnings after the sacrifice, so a scheme that drops earnings below the lower earnings limit can reduce or even remove the statutory payment altogether.
Tax credits and means-tested benefits
Salary sacrifice reduces taxable income, which can change entitlement to means-tested benefits and Child Benefit. For households near the £60,000 High Income Child Benefit Charge threshold, salary sacrifice can be the difference between losing some of the Child Benefit and keeping all of it.
Mortgages and credit
Some lenders treat the sacrificed amount as part of total remuneration for affordability; others look only at gross post-sacrifice salary. If you are about to apply for a mortgage, ask the lender how they calculate income, and ask your employer for a letter confirming the gross-pay equivalent of your scheme participation.
Lock-in period
Salary sacrifice schemes are usually a 12- to 36-month commitment. HMRC's rules allow opt-outs for genuine lifestyle changes (marriage, divorce, redundancy, a partner's pregnancy), but you cannot toggle in and out at will without losing the tax advantage. The pros and cons of salary sacrifice need to be weighed against your own job security and life plans.
Worked example: £40,000 salary, £2,000 into your pension
A basic-rate taxpayer earning £40,000 a year decides to sacrifice £2,000 of salary into their workplace pension over the year. Here is what changes.
| Line | Without salary sacrifice | With £2,000 pension sacrifice |
|---|---|---|
| Gross annual salary | £40,000 | £38,000 |
| Pension contribution from gross pay | £0 | £2,000 |
| Income Tax saved (20% of £2,000) | £0 | £400 |
| Employee NIC saved (8% of £2,000, 2026/27 rate) | £0 | £160 |
| Net cost of £2,000 pension contribution | n/a | £1,440 |
| Employer Class 1 NIC saved (15% of £2,000) | £0 | £300 |
The £2,000 lands in the employee's pension, but it only costs them £1,440 of take-home pay. That is a 28% saving, made up of 20% Income Tax and 8% National Insurance. The employer saves a further £300 in Class 1 secondary National Insurance. Where the employer agrees to pass that £300 back into the pension (an increasingly common arrangement), the total pension contribution rises to £2,300 for the same £1,440 of foregone net pay, taking the effective saving above 35%. For a higher-rate taxpayer, the same £2,000 contribution costs around £1,160 of take-home, an effective saving of more than 40%.
This is broadly the same arithmetic that HMRC walks through in its own worked example, where a £40,000 salary is reduced to £34,800 in exchange for £5,200 of childcare vouchers — only the benefit changes, the mechanics do not. For more on how the same logic applies to other benefits, see our guide to the benefits of salary sacrifice.
What about EV salary sacrifice?
Electric cars are the fastest-growing salary sacrifice category in the UK, and they follow the same tax mechanics described above with one important addition: there is a Benefit-in-Kind charge on the car. For pure EVs, that BiK charge is fixed at 4% of the manufacturer's P11D value in 2026/27, rising 1 percentage point a year to 9% in 2029/30. Because the BiK charge is so low, the Income Tax and National Insurance savings on the sacrificed salary still leave employees 20% to 50% better off than financing or leasing the same car privately.
The Electric Car Scheme is a UK salary sacrifice provider focused exclusively on electric vehicles. The scheme offers new and used EVs from a multi-funder pricing engine, builds Complete Employer Protection in from day one (covering resignation, redundancy, illness, parental leave and damage with no exclusion period), and runs at £0 set-up cost to the employer. It is offered by enterprise clients including Holland & Barrett, Leeds Bradford Airport, Millwall FC and Time Out Group PLC, and was named Best Salary Sacrifice Provider by Car Sloth in 2024 and 2025. If you want to see what an EV salary sacrifice scheme looks like in practice, the homepage is the best place to start, or compare providers on the EV salary sacrifice comparison page.
The bottom line
Salary sacrifice is one of the few legitimate, HMRC-recognised ways for UK employees to lower the cost of a major purchase or contribution by paying for it from pre-tax salary. Done properly, with a written contract variation, NMW protections, and a benefit that genuinely matters to the employee, it delivers 20% to 50% savings on pensions, cycle-to-work, workplace nurseries, employer-provided technology and ultra-low-emission cars. The rules are codified in HMRC's Employment Income Manual at EIM42750, and the official employer-facing guide at gov.uk sets out the PAYE and reporting requirements in full. Before signing, weigh the lock-in period, the National Minimum Wage floor, and any knock-on effect on statutory pay, mortgage applications or means-tested benefits, and ask the provider to show you the figures in writing.
