The publication of HMRC’s latest list of minimum wage offenders has highlighted a concerning trend: even well-established household names are falling foul of increasingly complex compliance requirements, with rising wage rates pushing more employers into the danger zone.

The most recent naming and shaming exercise reveals that minimum wage breaches are not confined to traditionally low-paying sectors or smaller employers struggling with resources. Caroline Harwood, head of employment tax at BDO, notes that "the latest list of employers named and shamed for failing to comply with minimum wage legislation includes some household names you wouldn’t necessarily think would be falling foul of the rules."

This development underscores a critical point often overlooked in discussions of minimum wage compliance: the distinction between deliberate underpayment and genuine technical errors has little bearing on the consequences employers face.

The Technical Minefield

HMRC’s approach to naming and shaming makes no differentiation between intentional wage theft and inadvertent compliance failures. As Harwood explains, "HMRC’s list doesn’t differentiate between those businesses who may have been deliberately underpaying their employees and those who have accidentally failed to comply."

The technical complexities that frequently catch employers off-guard include several common scenarios. Staff uniform costs present a particular pitfall when employers fail to account for these expenses in minimum wage calculations. Similarly, unpaid time spent on mandatory training courses can inadvertently reduce effective hourly rates below minimum wage thresholds.

Perhaps most surprisingly, salary sacrifice schemes designed to benefit employees can create compliance issues. Pension contributions and other salary sacrifice arrangements must be carefully considered within minimum wage calculations, as they can reduce the cash amount received by workers below statutory minimums.

Rising Rates Expand the Risk Zone

The recent substantial increases in minimum wage rates have fundamentally altered the compliance landscape. BDO’s research reveals the scale of this shift: 98% of employers report that the proportion of their staff earning within £2 per hour of the National Minimum Wage will rise following April 2025’s rate increases.

This statistic represents more than just numerical change – it signals a transformation in which employers historically operating comfortably above minimum wage levels now find themselves navigating previously unfamiliar compliance territory. Companies that never needed to scrutinize minimum wage calculations are suddenly required to develop expertise in an area that was previously irrelevant to their operations.

The financial and reputational consequences of minimum wage breaches remain severe regardless of intent. Employers face penalties reaching up to 200% of the underpayment, capped at £20,000 per affected worker. For organizations with multiple employees involved, these penalties can quickly escalate into substantial financial burdens.

However, the monetary penalty often pales in comparison to the reputational damage. Being named on HMRC’s public list can have lasting effects on employer brand, customer relationships, and talent attraction capabilities. In an era where corporate social responsibility and fair employment practices are increasingly scrutinized, appearing on this list can have consequences far beyond the immediate financial cost.

Proactive Compliance Strategies

The expanding risk landscape demands a more sophisticated approach to minimum wage compliance. Employers can no longer rely on simply setting wages above minimum levels and assuming compliance will follow automatically.

Regular pay audits should specifically examine minimum wage calculations, particularly for employees whose base rates fall within the expanded risk zone. These reviews must account for all potential deductions and additional costs that could affect effective hourly rates.

Training programs for payroll and HR teams need updating to reflect the technical complexities of minimum wage compliance. Understanding how uniform costs, training time, and salary sacrifice schemes interact with minimum wage calculations is now essential knowledge for a broader range of employers.

Documentation becomes crucial in demonstrating compliance intent. Clear records of how minimum wage calculations are performed, what factors are considered, and how potential issues are identified and resolved can provide valuable protection should disputes arise.

Looking Ahead

As Harwood emphasises, "great care is needed to ensure workers’ pay is correctly calculated." The combination of rising minimum wage rates and increasing technical complexity means that employers across all sectors must reassess their compliance procedures.

The current environment suggests that minimum wage compliance is evolving from a concern primarily affecting low-wage employers to a broader business risk requiring systematic attention across the employment spectrum. Organizations that recognize this shift and adapt their processes accordingly will be best positioned to avoid joining the growing list of named offenders.

For many employers, the question is no longer whether they need to worry about minimum wage compliance, but whether their current systems are robust enough to handle the new reality of expanded risk exposure.
