Salary Sacrifice and Minimum Wage 2026/27

Published by the UK Money Calculators editorial team. Last updated for the 2026/27 tax year.

Salary sacrifice reduces your contractual salary, not just your take-home pay. NMW rules apply to contractual cash pay. An employer cannot run a salary sacrifice arrangement that takes your hourly cash pay below the NMW rate. In 2026/27 the NMW for workers aged 21 and over is £12.21 per hour. If sacrifice would breach this, the arrangement cannot go ahead.

Why NMW matters for salary sacrifice

Salary sacrifice is a change to your contractual salary. It genuinely reduces the salary you are entitled to — it is not simply a payroll deduction. HMRC is clear that sacrifice cannot reduce an employee's pay below NMW for any pay reference period.

The distinction matters because:

Tax deductions (income tax, NI) do not count for NMW — these come out of pay after NMW is assessed.
Salary sacrifice does count — it reduces the cash pay before NMW is assessed.
If a sacrifice takes cash pay below NMW, the employer is in breach of the National Minimum Wage Act, which can result in penalties.

Checking NMW compliance is the employer's legal responsibility. But as an employee it is worth knowing whether you are at risk before agreeing to any sacrifice.

National Minimum Wage 2026/27

The National Living Wage for workers aged 21 and over is £12.21 per hour for 2026/27. Lower rates apply for younger workers and apprentices. Rates are reviewed annually — check GOV.UK for the current figures as they may have changed.

Worked example

Employee earning close to NMW

An employee aged 21+, working 37.5 hours per week, earning £23,000 per year.

Annual hours: 37.5 × 52 = 1,950
Effective hourly rate: £23,000 ÷ 1,950 = £11.79/hr
NMW 2026/27: £12.21/hr

At £11.79/hr this employee is already below the 2026/27 NMW. That means either the salary is not compliant, or there are additional pay elements such as commission or allowances that bring it above NMW.

Where the effective hourly rate is at or near £12.21/hr, salary sacrifice is not possible. Any sacrifice would push the rate below the legal minimum. Even a small pension sacrifice would be blocked.

For an employee on exactly NMW, any sacrifice at all is blocked unless the contract includes pay elements outside the sacrifice agreement.

Who is most commonly affected

The limitation most commonly affects:

Lower-paid workers whose salaries are close to the NMW threshold.
Part-time workers where the hourly rate may not look low but total sacrifice would breach the threshold for a pay period.
Seasonal or variable-hours workers where pay fluctuates across reference periods.
Young workers on the lower NMW/NLW rates (though these rates are lower, the principle is the same).

If you think you might be affected, ask payroll to check before agreeing to any sacrifice.

Employer responsibilities

It is the employer's legal duty to ensure salary sacrifice doesn't cause NMW non-compliance. A compliant employer will:

Check each employee's hourly equivalent pay before setting up a sacrifice.
Review compliance each pay period, particularly where hours vary.
Tell you if your salary means you cannot participate in a scheme — or can only participate up to a lower limit.

If an employer allows a sacrifice that causes NMW non-compliance, HMRC can enforce back-payment and issue penalties. Employees who believe their rights have been breached can contact ACAS or raise a complaint with HMRC's NMW team.

Common mistakes

Confusing take-home pay with contractual pay. NMW applies to contractual cash pay, not what you receive after tax deductions.
Assuming the employer has checked. Not all employers verify this rigorously. If you are near NMW, ask explicitly before signing.
Thinking holiday pay or overtime avoids the issue. Different pay elements are treated differently for NMW purposes — your employer should calculate this correctly.
Joining a scheme mid-year after a pay change. A new lower salary or reduced hours could push you below the threshold even if you were previously fine.

Frequently asked questions

Whose responsibility is it to check NMW compliance?

It is the employer's legal responsibility to ensure salary sacrifice does not reduce any employee's pay below the National Minimum Wage. However, as an employee you should understand the rules and ask your employer to confirm compliance, particularly if your salary is close to the NMW threshold.

Can I sacrifice holiday pay instead of salary?

No. HMRC does not allow the sacrifice of holiday pay as part of a salary sacrifice arrangement. Your statutory holiday entitlement and its pay must be based on your normal (pre-sacrifice) remuneration under Working Time Regulations. Sacrificing holiday pay is a separate legal concept and not permitted in this context.

What if I am already on the National Minimum Wage?

If your current pay is at or near NMW, salary sacrifice is very unlikely to be available to you in any amount. Any sacrifice — however small — would immediately breach the NMW requirement. Your employer should inform you of this when you apply to join a salary sacrifice scheme.

Does the NMW limit apply to all types of salary sacrifice?

Yes. The NMW rule applies to all salary sacrifice arrangements — pension, cycle to work, EV car or any other scheme. The type of benefit you receive in return makes no difference; the restriction is on the cash pay falling below NMW.

Where can I find the current NMW rates?

Always check the current rates at GOV.UK National Minimum Wage rates. Rates change each April. The £12.21/hr figure quoted here is for workers aged 21+ for 2026/27 and may have been updated since publication.
