SME leaders increasingly feel squeezed by rising costs, workforce pressures and, above all, a shifting tax environment that is complex, costly and difficult to plan around, writes Paul Turner, vice-president, UK and Ireland at the Chartered Institute of Management Accountants (CIMA)

Small and medium-sized enterprises (SMEs) remain the backbone of the UK economy. In 2025, they accounted for 99% of all UK businesses, employing around 16.9 million people and generating over half of private sector turnover. Yet behind this ambition lies growing frustration – and for accountants advising SME clients or management within the organisation, this moment matters.

The challenges business face today are not merely operational or fiscal, they are strategic. Business leaders are looking for clarity, confidence and direction at a time when traditional levers for growth feel constrained.

This is where our profession can add the greatest value. Helping businesses navigate pressure, make informed decisions and move from reacting to constrictive cost factors, such as tax rises or supply chain issues, to proactively creating growth opportunities.

A tax system constraining growth

Evidence from CIMA’s UK SME Survey 2026 paints a clear picture. While business ambition remains strong, with just over half of SMEs expecting to grow over the next year, taxation has emerged as the single biggest barrier to turning that ambition into action.

Seven in 10 SMEs say tax is restricting their ability to grow. Employer taxes are cited most frequently, with more than 80% of respondents identifying them as a major obstacle.

Two-thirds say employee taxes are discouraging recruitment altogether. For smaller businesses, even marginal increases in employment costs can materially alter hiring, investment and expansion decisions.

Fiscal drag is further compounding the challenge. Frozen thresholds are quietly increasing tax liabilities as wages and profits rise in nominal terms. Nearly half of SMEs say this “silent escalator” is significantly constraining growth, eroding cash flow and reducing the headroom needed for reinvestment. For leaders trying to plan in an uncertain economic environment, this lack of predictability makes long-term decision-making harder and riskier.

Hiring hesitation, productivity pressure

These pressures are having visible consequences. Almost half of SMEs report being understaffed, while more than a quarter say they want to recruit but are reluctant to do so. Rising employment costs, alongside uncertainty about future demand, mean recruitment is increasingly viewed as a financial risk rather than a growth enabler.

Skills shortages are beginning to bite too. Three in 10 SMEs say gaps in capability are limiting productivity growth, particularly in areas related to digital adoption, automation and financial insight. Businesses know they need to modernise, but many lack the capacity, confidence or data to act decisively.

The management accountant’s role

In this environment, SMEs are not simply looking for reassurance, they are looking for leadership.

The dilemma they face having ambitions for growth, yet curtailed by a need to be prudent given the current economic climate, presents an opportunity for management accountants to broaden conversations beyond cost control and compliance, towards, productivity workforce planning and long-term value creation.

Management accountants are uniquely positioned to help senior teams make sense of complexity, particularly where tax policy, cash flow, people strategy and investment decisions intersect.

Practical support can include modelling the true cost of hiring, assessing the impact of tax changes on long-term forecasts, and identifying where cash is being constrained by inefficiencies rather than growth investment. By reframing tax from a fixed burden to a managed variable, accountants can help business leaders see clearer trade-offs and make more confident decisions.

Crucially, this support depends on timely, accurate and accessible data. Real time financial insight is no longer a nice to have for SMEs operating on tight margins, it is essential.

Turning pressure into progress

Despite the challenges, the majority of SMEs still want to grow, invest and contribute to a competitive UK economy. What they need is support that reflects the realities they face.

For management accountants, the challenge is clear, to be integral to helping clients or your business navigate a tax burdened environment with confidence, use digital tools to unlock better insight, and support senior leaders in turning constraint into informed action.

Get this right, and accountants will not just help SMEs weather volatility, they will help them make better decisions, invest with purpose, and remain resilient engines of growth for the UK economy.
