How regulated industries are changing compliance expectations for accountants
Compliance for UK accountants has changed considerably in a short space of time. Clients operating in heavily regulated sectors now arrive with far more complex obligations than they did even three years ago. That complexity flows directly into the work accountants must perform, and the standards they must meet, simply to serve those clients well.
This isn't a theoretical concern. Regulatory bodies are enforcing at a higher level. Digital reporting mandates are tightening and the range of licensed industries demanding specialist compliance support continues to expand. Practices that fail to keep pace risk both reputational harm and regulatory exposure of their own.
Why client compliance demands are growing fast
Anti-money laundering obligations sit at the centre of much of this pressure. The Financial Conduct Authority imposed over £176 million in fines for AML breaches in 2024, signalling a regulatory environment with little tolerance for procedural gaps. For accountants, this means client onboarding, risk assessments, and ongoing monitoring have all become more demanding processes.
HM Treasury's planned move toward a Single Professional Services Supervisor under the FCA would consolidate AML oversight currently spread across bodies, including ICAEW, which supervises around 9,500 firms. Standardised, risk-based scrutiny is likely to follow, raising the floor for what counts as adequate compliance practice across the profession.
How licensed online sectors raise reporting complexity
Beyond traditional financial services, licensed online platforms are generating a distinct category of compliance challenge. For instance, with the UK’s 2026 roadmap for digital assets, many Fintechs are now "tokenising" funds. Accountants must now reconcile traditional ledgers with distributed ledgers.
Starting in May 2026, crypto-asset firms can request meetings with the FCA to ensure their financial reporting meets the new FSMA (Financial Services and Markets Act) regime. Accountants are the primary architects of these submissions.
Operators in sectors like online gaming, on the other hand, must meet very strict licensing, financial reporting, and anti-fraud requirements. and when those businesses engage accountants, that complexity transfers directly. Industry resources such as gamblinginsider.com show just how varied and technically demanding the regulatory environment for licensed online platforms has become. Most international platforms are licesnsed outside of the country, and compliance and regulations will differ significantly.
Accountants advising clients in these spaces need to understand not just tax obligations but also the licensing conditions, source-of-funds documentation requirements, and transaction monitoring expectations their clients face. This is a meaningfully different scope of work from standard practice, and it demands a meaningfully different level of preparation.
What accountants must document for regulated clients
ICAEW's AML supervision of 1,185 firms in 2024/25 found that 20% were non-compliant or partially non-compliant, with customer due diligence failures the most common weakness, particularly around risk assessments and verification procedures. According to ICAEW's compliance analysis, ineffective CDD remains the central issue across supervisory reviews.
For accountants working with regulated clients, documentation must now go well beyond standard engagement letters. Source-of-funds checks, beneficial ownership verification, and ongoing risk reassessment are expected as a baseline, not as exceptional measures.
Adapting practice workflows for compliance-heavy portfolios
Digital reporting mandates add another layer of operational change. Since April 2026, Making Tax Digital for Income Tax Self-Assessment has required quarterly digital submissions.
This is directed at self-employed individuals and property businesses with gross income above £50,000. Practices with regulated clients in this bracket must now embed MTD-compliant workflows into their standard processes.
The bigger picture is structural. Compliance is no longer a box-ticking exercise that sits alongside accounting work; it is increasingly central to it. Practices that invest time in understanding the specific regulatory environments their clients operate within will be better positioned to provide real value.
They are also more likely to retain complex clients over the long term. At the same time, stronger oversight helps reduce the professional risks that can come from inadequate compliance and regulatory gaps.
