Minimum Wage: The Employer Obligations in Full

The National Living Wage rose to £12.71 an hour from 1 April 2026, a 4.1% increase for workers aged 21 and over ^[1][2]. An employer who pays below the legal rate faces a penalty of 200% of the underpayment, capped at £20,000 per worker, and public naming once arrears pass £500 ^[3]. Minimum wage compliance is not a matter of setting an hourly rate and forgetting it.

Most minimum wage breaches are not deliberate. HMRC enforcement data shows the majority of named employers underpaid through avoidable mistakes: unpaid working time, deductions that quietly drag pay below the threshold, and the wrong rate applied to apprentices ^[3]. The obligation is not simply to pay the rate; it is to make sure that every worker, in every pay reference period, actually receives at least the rate for every hour that counts as work.

This article sets out the full range of employer duties: the correct rates and age bands, who is entitled, how compliance is tested across a pay reference period, which deductions breach the rules, the payslip and record-keeping obligations, and what enforcement looks like when it goes wrong. It is written for UK employers who run their own payroll and want to stay on the right side of the line.

Key takeaways

• The National Living Wage for workers aged 21 and over is £12.71 an hour from 1 April 2026, with lower rates for younger workers and apprentices ^[1][2].
• Compliance is tested as an average across a pay reference period, which can never exceed one calendar month ^[4].
• Deductions for items connected with the job, such as uniforms or tools, reduce minimum wage pay and are a leading cause of breaches ^[5].
• All workers have been entitled to an itemised payslip since 6 April 2019, showing hours where pay varies by time worked ^[6].
• HMRC can impose a penalty of 200% of arrears, up to £20,000 per worker, reduced by half if the employer pays within 14 days ^[3].

The rates every employer must apply

The minimum wage is not a single figure. It is a set of hourly rates that vary by age band and by apprentice status, and every rate changed on 1 April 2026 ^[2]. An employer must apply the correct rate to each worker based on their age band at the start of each pay reference period ^[1]. The table below sets out the rates in force from that date.

An employer who pays a rate correct for one age band but forgets to move a worker up when they have a birthday will underpay from that point. Age-band transitions are one of the routine failure points HMRC looks for ^[3]. Payroll that tracks each worker's date of birth and applies the right rate automatically removes that risk, which is one reason employers move day-to-day pay onto HMRC-recognised payroll software for SMEs rather than a spreadsheet.

The apprentice rate catch

The apprentice rate of £8.00 an hour applies only to apprentices who are under 19, or who are 19 or over and in the first year of their apprenticeship ^[1]. Once an apprentice is 19 or over and has completed the first year, they move to the rate for their age band ^[7]. A 21-year-old apprentice in their second year is entitled to the full National Living Wage of £12.71, not the apprentice rate ^[1].

This transition is a common and expensive mistake. HMRC enforcement rounds have repeatedly found employers paying the apprentice rate to workers who should have moved to their age rate, and the resulting arrears stretch back across every affected pay period ^[3]. An employer taking on apprentices needs a diary of when each apprentice turns 19 and when their first year ends ^[7].

Who is entitled to the minimum wage

The minimum wage reaches further than many employers assume. It covers not only full-time and part-time employees but also casual, zero-hours, agency, and piecework workers, provided they are above compulsory school leaving age ^[8]. A small group of people are outside the rules, and the distinctions matter because getting them wrong is itself a breach.

A crucial point for employers is that a worker's tax label does not settle their minimum wage entitlement. HMRC assesses minimum wage status separately, so a person treated as self-employed for tax may still qualify for the minimum wage as a worker ^[8][9]. Employers relying on self-employed contractors should confirm the true working relationship rather than assume the tax treatment answers the question ^[9].

How compliance is actually tested

The most misunderstood part of the minimum wage is that it is not tested shift by shift. It is tested as an average hourly rate across a pay reference period, and the way that period and its hours are defined determines whether an employer complies ^[4].

The pay reference period

A pay reference period is the pay cycle, weekly, fortnightly or monthly, but it can never be longer than one calendar month ^[4]. Minimum wage compliance is measured by dividing the qualifying pay for the period by the qualifying hours, and comparing the result against the rate ^[5]. A payment counts in the period it is actually paid, not necessarily the period in which the work was done ^[4].

Because the test is an average, a single generous week cannot cure a shortfall in another period. Each pay reference period stands on its own, which is why a worker whose hours spike without a matching rise in pay can slip below the minimum in that period alone ^[5]. The interaction with pay frequency is covered in more depth in the guide to pay frequency in the UK.

Working time that must be paid

A frequent cause of underpayment is unpaid working time. HMRC enforcement has found large numbers of employers failing to pay for all the time a worker is required to be on duty, including time spent setting up before a shift, changing into a uniform on the premises, queuing to clock in, and clearing up afterwards ^[3]. If a worker is required to be at the workplace or on duty, that time generally counts as working time and must be paid ^[5].

Rounding clock-in times against the worker, unpaid mandatory training, and unpaid travel between assignments are all treated the same way ^[3]. An employer that captures only rostered hours, and not the real hours a worker is on duty, risks a shortfall it never intended ^[5].

Deductions that push pay below the rate

Deductions are the other major trap. Some deductions reduce a worker's minimum wage pay, and if they take the average below the rate, the employer is in breach even though the headline hourly figure looked compliant ^[5]. The dividing line is whether the deduction is for the employer's benefit or connected with the job ^[5].

Salary sacrifice deserves particular care. A pension or benefit sacrifice that is attractive for tax reasons can still breach the minimum wage if it drops a worker's cash earnings below the threshold, and the minimum wage rules override the arrangement ^[5]. Payroll that flags when a deduction risks pushing a worker below the rate protects the employer from a breach it would not otherwise spot, a check built into small business payroll systems designed for compliance.

Accommodation, the only benefit that counts

Accommodation is the single benefit in kind that can count towards minimum wage pay. Where an employer provides accommodation, an offset of £11.10 a day, or £77.70 a week, applies from 1 April 2026 ^[2][10]. If the employer charges more than the offset, the excess reduces the worker's minimum wage pay ^[10]. No other benefit in kind, such as meals or a company vehicle, can be counted ^[10].

Payslip and record-keeping obligations

Paying the right amount is only half the duty. Employers must also document it. Since 6 April 2019, all workers, not only employees, have been entitled to an itemised payslip, a change that extended payslips to an estimated 300,000 workers for the first time ^[6].

A compliant payslip must show gross pay, net pay, and each variable deduction separately with its purpose ^[11]. Where a worker's pay varies by the amount of time worked, the payslip must also show the total number of hours, so an hourly worker can check the calculation for themselves ^[6][11]. A salaried worker whose pay does not vary by time does not need hours shown ^[6]. The payslip must be provided at or before the time wages are paid ^[11].

Record-keeping runs alongside. Minimum wage records must be kept for at least six years and must be capable of being produced for any single pay reference period in one document ^[4]. A worker has the right to inspect their own minimum wage records, and refusing that request is a criminal offence ^[8]. Employers that produce compliant, itemised payslips through an instant payslip generator or full payroll keep the documentary trail HMRC expects.

What happens when an employer underpays

HMRC enforces the minimum wage, and the consequences of underpayment are structured to make non-compliance expensive. An officer can inspect records, interview workers, and issue a Notice of Underpayment requiring the employer to repay all arrears to every affected worker ^[3].

The reputational cost of the naming scheme often outweighs the penalty. The Department for Business and Trade publishes rounds of named employers, and inclusion follows even where the underpayment was an honest error rather than deliberate non-payment ^[3]. Workers can also check their own pay through the government's Check Your Pay campaign, which raises the likelihood that a shortfall is reported ^[12]. Accountants running payroll for multiple clients typically monitor minimum wage exposure across all of them from a single multi-client payroll dashboard.

Tips do not count towards the minimum wage

A final obligation catches hospitality and service employers in particular. Tips, gratuities and service charges can never count towards minimum wage pay, regardless of how they are paid ^[10]. An employer cannot use tips to top up wages to the legal rate; the minimum wage must be met from wages alone ^[10].

Since 1 October 2024, the Employment (Allocation of Tips) Act 2023 has also required employers with control over tips to pass on 100% of them to workers, distribute them fairly, and keep a written tips policy ^[13]. The two rules work together: tips must be paid on top of at least the minimum wage, and must then be allocated fairly under the Act ^[13].

Check a worker against the minimum wage

To confirm a worker is paid at least the legal rate, the Moonworkers minimum wage calculator applies the correct rate by age band and apprentice status for the 2026-27 tax year, and runs the employer compliance check across a pay reference period once deductions are taken into account.

Conclusion

Minimum wage compliance is a system of interlocking duties, not a single hourly figure. The rate has to be right for each worker's age band, the hours counted have to include all working time, deductions must not erode the pay below the threshold, and the whole calculation has to be documented on a payslip and kept on file for six years. A failure at any one of those points produces a breach, and the enforcement regime is deliberately weighted to make breaches costly.

For most employers, the way to close the gaps is to move the calculation off manual processes and onto payroll that tracks age bands, flags risky deductions, records hours, and produces compliant payslips as a matter of course. The minimum wage will keep rising each April, and the employers least exposed to enforcement are those whose systems apply the new rates the moment they take effect.

Frequently asked questions

What is the minimum wage an employer must pay from April 2026?

From 1 April 2026 the National Living Wage for workers aged 21 and over is £12.71 an hour, the 18 to 20 rate is £10.85, the under-18 rate is £8.00, and the apprentice rate is £8.00 ^[1][2]. An employer must apply the correct rate for each worker based on their age band at the start of each pay reference period ^[1].

Can an employer count tips towards the minimum wage?

No. Tips, gratuities and service charges can never count towards minimum wage pay, whatever method is used to pay them ^[10]. The minimum wage must be met from wages alone, and since 1 October 2024 employers must also pass on 100% of tips to workers under the Employment (Allocation of Tips) Act 2023 ^[13].

Do deductions for uniforms breach the minimum wage?

They can. A deduction for a uniform, tools or other items connected with the job reduces a worker's minimum wage pay, and if it takes the average below the rate the employer is in breach ^[5]. Deductions for income tax, National Insurance, student loans and genuine pension contributions do not reduce minimum wage pay ^[5].

What penalty does HMRC charge for underpaying the minimum wage?

HMRC can require the employer to repay all arrears and charge a penalty of 200% of the underpayment, up to £20,000 per worker, with a minimum of £100 ^[3]. The penalty is halved if the employer pays the arrears and half the penalty within 14 days, and employers are named publicly once arrears exceed £500 ^[3].
