Salary sacrifice is an agreement to swap part of your contractual pay for a benefit your employer provides, most often extra pension contributions. Done properly, it cuts income tax and National Insurance for you and employer National Insurance for the business. Done carelessly, it can push pay below the minimum wage or shrink maternity pay. This guide is for employees deciding whether to sign up and for small employers setting a scheme up in 2026. It covers how pension sacrifice saves money, which other benefits still work under HMRC's optional remuneration rules, the minimum wage floor, the knock-on effects, and the £2,000 National Insurance cap that starts in April 2029.

Quick answer

Salary sacrifice means your contract is changed so you give up some pay in return for a benefit. For pension contributions you save income tax and employee National Insurance (8% or 2%) on the amount sacrificed, and your employer saves 15%. From 6 April 2029, only the first £2,000 a year of pension sacrifice will be National Insurance-free.

  • Most other benefits taken by sacrifice are taxed on the higher of the pay given up and the benefit value (OpRA rules)

  • Still tax-efficient: pensions, pension advice, cycle-to-work, cars at 75g/km or less, older childcare schemes

  • Cash pay must never drop below the National Minimum Wage (£12.71 an hour for workers 21 and over)

  • Lower contractual pay can reduce statutory maternity pay, some benefits and borrowing capacity

  • The 2029 cap doesn't affect income tax relief or normal employer pension contributions

How salary sacrifice works

In a salary sacrifice arrangement, the employee agrees to a lower cash salary and the employer provides a benefit worth roughly the same. Because the employee is no longer entitled to that slice of pay, no income tax or National Insurance is due on it, and the employer pays no employer National Insurance either. With a pension, the employer pays the sacrificed amount into the scheme as an employer contribution, which is free of tax and National Insurance.

The legal mechanism is what makes it work. HMRC's guidance says the employment contract must be changed, with the employee's agreement, every time the arrangement changes. HMRC would want to see evidence of the contractual variation and payslips from before and after, to be satisfied the change took effect when claimed and wasn't applied retrospectively. A payroll deduction labelled "salary sacrifice" without a contract change is just a deduction from pay, and tax and National Insurance are due on the full salary.

That's also why most schemes only let you join, leave or change the amount at set times, such as once a year at a scheme window or after a lifestyle event like a birth, marriage or a partner's redundancy. Frequent switching suggests the employee never really gave up their entitlement.

Pension salary sacrifice: worked examples

The clearest way to see the saving is to compare it with an ordinary pension contribution. The examples use 2026-27 rates for England, Wales and Northern Ireland: employee Class 1 National Insurance at 8% between £12,570 and £50,270 and 2% above, and employer National Insurance at 15%.

A basic-rate employee

Priya earns £35,000 and pays 5% (£1,750) into her workplace pension.

Net pay arrangement (no sacrifice)Salary sacrifice
Contractual salary£35,000£33,250
Pension going in£1,750£1,750
Income tax saved (20%)£350£350
Employee NI saved (8%)£0£140
Real cost to Priya£1,400£1,260
Employer NI saved (15%)£0£262.50

Priya keeps £140 a year more in her pocket for the same pension, and her employer saves £262.50. Some employers pass all or part of their saving into the employee's pension, which is worth asking about.

If Priya's scheme used relief at source instead of a net pay arrangement, the result would be the same on income tax at the basic rate: she would pay £1,400 from net pay and the provider would claim £350 from HMRC to top it up. Neither method saves National Insurance, which is the extra that only salary sacrifice delivers. A higher-rate taxpayer in a relief at source scheme has to claim the extra relief through Self Assessment or by contacting HMRC; with salary sacrifice it's given automatically through payroll, which is one of its practical advantages.

The saving compounds over a career. Keeping the £140 in her pension rather than her pocket, or asking her employer to add its £262.50 saving, would raise Priya's total contributions by nearly a quarter without costing her any more take-home pay.

A higher-rate employee

Tom earns £70,000 and sacrifices 10% (£7,000). His remaining salary of £63,000 is still above the upper earnings limit, so his employee National Insurance saving is only 2%: £140. His income tax saving is 40%, or £2,800, the same as he'd get from any pension contribution. His employer saves £1,050.

For higher earners the income tax side dominates, but salary sacrifice also lowers adjusted net income, which matters at two cliff edges. If income falls from just above £100,000 towards it, part of the lost Personal Allowance comes back, so sacrificing £10,000 from a £110,000 salary restores £5,000 of allowance and gives an effective relief of around 60%. And for parents, the High Income Child Benefit Charge starts at £60,000 and fully claws back Child Benefit at £80,000; bringing adjusted net income down through sacrifice reduces or removes the charge.

The £2,000 National Insurance cap from April 2029

The biggest change to salary sacrifice in years has now been legislated. The government has announced that only the first £2,000 a year of pension contributions made through salary sacrifice each year would stay free of National Insurance. The National Insurance Contributions (Employer Pensions Contributions) Act 2026 received Royal Assent in spring 2026 after Parliament rejected Lords amendments to raise the limit to £5,000 and to exempt some small employers and charities. The Act gives the Treasury power to set the limit by regulations, and the first limit is to be £2,000 a year from 6 April 2029.

GOV.UK's summary of the change says:

  • pension contributions sacrificed above £2,000 a year a year will be subject to employee and employer National Insurance, in the same way as other employee pension contributions;
  • employer pension contributions (not funded by a sacrifice) stay free of National Insurance;
  • income tax relief on pension contributions is unchanged, within the usual limits such as the £60,000 annual allowance;
  • employees don't need to do anything; employers will report the total sacrificed through their payroll software, and HMRC will publish more guidance before April 2029.

The government says most employees making typical contributions won't be affected. Using 2026-27 rates as a guide, Priya's £1,750 sits under the cap and keeps its full saving. Tom's £7,000 doesn't: £5,000 would become liable to National Insurance, costing him about £100 a year at 2% and his employer about £750 at 15%. A basic-rate employee sacrificing £3,000 would lose National Insurance relief on £1,000: about £80 for them and £150 for the employer.

Several details are still to come in regulations: how the limit works for someone with more than one employer, how bonus sacrifice is treated, and exactly what payroll has to report. Employers with generous sacrifice schemes have until April 2029 to plan, but the decisions are worth making early. Options include absorbing the extra employer National Insurance, restructuring so more of the pension is funded by a straightforward employer contribution, or changing contract terms, which may need consultation and employee consent. Whatever the choice, total contributions must still meet the automatic enrolment minimums of 8% of qualifying earnings, with at least 3% from the employer.

Beyond pensions: the OpRA rules for other benefits

Salary sacrifice used to be common for gym memberships, phones, health screening and cars of every kind. Since 6 April 2017, HMRC's optional remuneration arrangement (OpRA) rules in section 69A of the Income Tax (Earnings and Pensions) Act 2003 have removed most of that advantage. The Employment Income Manual describes two types: Type A, where you give up a right to earnings in return for a benefit (classic salary sacrifice), and Type B, where you choose a benefit instead of a cash alternative (flexible benefits).

Under OpRA, the taxable value of the benefit is the higher of the cash given up and the normal benefit-in-kind value. Because you're usually giving up at least as much cash as the benefit is worth, there's no tax saving, and the employer pays Class 1A National Insurance on the benefit. Transitional protection for arrangements made before April 2017 ended in April 2021.

Some benefits are excluded from OpRA, so sacrifice still works for them:

Taxed on the higher of pay given up and benefit value

Electric car schemes remain popular because a zero-emission car's benefit-in-kind charge is small compared with the salary given up. Our company car tax guide shows the appropriate percentages rising each year to 2029-30, which will narrow the saving gradually.

The minimum wage floor

HMRC's guidance is blunt: a salary sacrifice arrangement must not reduce an employee's cash earnings below National Minimum Wage rates, and employers must have procedures to cap the sacrifice so minimum wage is maintained. The legislation doesn't recognise "salary sacrifice" as anything special; the reduced contractual pay is simply the pay that counts for minimum wage purposes, measured over the pay reference period.

Here's how the headroom works. Jordan is 24, works 37.5 hours a week and is paid £13.00 an hour, so £487.50 a week. The National Living Wage for 2026-27 is £12.71 an hour, so his minimum pay for those hours is £476.63. The most he can sacrifice is £10.87 a week, about £565 a year. If he joined a cycle-to-work scheme at £20 a week, his employer would breach minimum wage law.

The headroom also changes each April. The Low Pay Commission's central estimate for the April 2027 National Living Wage is £13.18 an hour. If Jordan's rate stayed at £13.00, he'd already be below that from April 2027 before any sacrifice, so the employer would have to raise his pay and recheck the sacrifice. Employers should build a minimum wage check into every April pay review and every new sacrifice application. Our National Minimum Wage guide explains pay reference periods and what counts as working time.

Watch for unpaid leave and short months too. A fixed weekly sacrifice taken from a week of reduced hours can dip below the floor even when it's fine in a normal week. Good payroll software flags this; if yours doesn't, set the sacrifice as a percentage and add a minimum wage check to the pay run.

Effects on statutory pay, benefits and borrowing

A lower contractual salary has knock-on effects that HMRC's guidance specifically warns about.

Statutory pay. Statutory Maternity Pay, Paternity Pay, Adoption Pay and Sick Pay depend on average weekly earnings, and those are measured after the sacrifice. Statutory Maternity Pay for the first six weeks is 90% of average weekly earnings, so a sacrifice reduces it directly. If the sacrifice pushes average earnings below the lower earnings limit of £129 a week, no statutory pay is due at all. Many employers keep pension contributions going during family leave as a contractual benefit; check the scheme rules. Our Statutory Maternity Pay guide explains the calculation period.

State benefits and the State Pension. Earnings-related benefits such as Maternity Allowance can be reduced, and if your earnings fall below the lower earnings limit you may stop building qualifying years for the State Pension. For most employees this isn't an issue, but it matters for part-time staff close to the threshold.

Mortgages, life cover and redundancy pay. Lenders often use contractual salary, though many accept a pre-sacrifice figure with a letter from the employer. Death-in-service cover, pay rises and statutory redundancy pay may be calculated on the reduced salary unless the scheme uses a "reference salary". Ask before you sign up, and keep a copy of the employer's policy.

Universal Credit and tax credits. Because take-home pay is lower, Universal Credit may increase slightly, which is a quirk rather than a reason to sacrifice.

Setting up a salary sacrifice scheme (employers)

For a small employer, a pension salary sacrifice scheme is mainly paperwork and payroll configuration. The steps:

Setting up pension salary sacrifice

  1. 1

    Check your pension scheme and payroll can support it

    The provider must accept the sacrificed amount as an employer contribution. Most automatic enrolment providers do.

  2. 2

    Decide the rules

    Who can join, when changes are allowed, whether you pass on your National Insurance saving, and how family leave and low earners are protected.

    Tip: A percentage sacrifice with a minimum wage cap is easier to keep compliant than a fixed amount.

  3. 3

    Write it into the contract

    Issue a contract variation letter or a revised contract, get the employee's agreement, and keep it on file with before-and-after payslips.

  4. 4

    Configure payroll

    Reduce gross pay by the sacrifice, pay the same amount to the pension as an employer contribution, and add a minimum wage check.

  5. 5

    Review every April

    Recheck minimum wage headroom when rates change, and plan now for reporting sacrificed pension above £2,000 a year from 6 April 2029.

Pension contributions through sacrifice don't go on a P11D, because employer pension contributions to a registered scheme are exempt. Benefits caught by OpRA are reported as benefits in kind. For automatic enrolment, sacrificed contributions count as employer contributions, so you still need to meet the minimum total; our automatic enrolment guide covers qualifying earnings and the minimums.

Common mistakes

The mistakes that cause most problems are predictable. Employers start deductions before the contract is varied, so HMRC can treat the arrangement as ineffective and claim the tax and National Insurance back. They let low-paid staff join without a minimum wage check, which turns a perk into an underpayment that the Fair Work Agency can enforce. They forget to tell employees about the effect on statutory pay, leading to disputes when someone goes on maternity leave.

Employees, for their part, sometimes sacrifice so much that their mortgage application or life cover is affected, or join a scheme without realising they can't leave until the next window. For pensions, it's also worth checking you're not already near the annual allowance of £60,000, or the tapered allowance if your income is very high; sacrifice counts towards it in the same way as any other contribution. Our pension tax relief guide explains the limits.

What to do next

If you're an employee, ask HR whether your pension scheme offers salary sacrifice, whether the employer passes on its National Insurance saving, and how the arrangement treats maternity pay and pay rises. If you're an employer, model the saving across your payroll now, add a minimum wage check, and diary a review ahead of the April 2029 cap. The employer National Insurance guide shows how the 15% rate and the £5,000 threshold work, and the salary slip generator helps you show staff the before-and-after payslip.

Frequently asked questions

For most employees, yes. You get the same income tax relief as an ordinary pension contribution, plus you save employee National Insurance on the amount sacrificed: 8% for most earners, 2% above the upper earnings limit. Your employer saves 15% employer National Insurance and may pass some of that into your pension. The trade-off is a lower contractual salary, which can affect statutory pay, mortgages and some benefits.
