As HMRC and Companies House continue introducing new compliance requirements, choosing a qualified and regulated accountant has never been more important.
Recent warnings from the AAT, ACCA and ICAEW highlight the risks posed by unregulated tax advisers and refund agents operating across the UK. At the same time, the introduction of identity verification requirements and Authorised Corporate Service Provider (ACSP) regulations means businesses are increasingly expected to work with trusted professionals who meet recognised standards.
While low-cost tax services and refund specialists may seem attractive, many clients only discover problems when HMRC opens an enquiry, rejects a claim, or issues penalties.
The Risks of Using an Unregulated Tax Adviser
Unlike members of professional bodies such as AAT, ACCA or ICAEW, unregulated advisers are not subject to professional oversight, disciplinary procedures, continuing professional development requirements, or mandatory professional indemnity insurance.
This can expose clients to risks including:
• Incorrect tax returns and HMRC penalties
• Tax refunds being redirected through third parties
• Poor record keeping and compliance failures
• Difficulty recovering losses if something goes wrong
• Firms disappearing after taking payment
Many individuals and small business owners only become aware of issues months later when contacted by HMRC.
If you are already facing compliance issues, penalties or late filing problems, see our HMRC Penalty Help and Late Tax Return Support guide.
What Professional Regulation Means
A qualified accountant is accountable to a recognised professional body and must meet strict standards designed to protect clients.
Professional regulation typically includes:
• Continuing Professional Development (CPD)
• Professional indemnity insurance
• Ethical and conduct requirements
• Anti-money laundering supervision
• Ongoing monitoring and compliance checks
These safeguards help ensure advice remains accurate, professional and up to date.
ACSP Registration and Identity Verification
One of the biggest changes affecting UK businesses in 2026 is the introduction of identity verification requirements through Companies House reforms.
Many directors, people with significant control (PSCs) and company officers must now verify their identity. This process can be completed directly with Companies House or through an Authorised Corporate Service Provider (ACSP).
An ACSP is a regulated professional firm authorised to carry out identity verification and Companies House filings on behalf of clients.
Not every accountant or tax adviser can become an ACSP. To qualify, firms must already be supervised under anti-money laundering regulations and meet Companies House requirements.
This means ACSP status provides an additional layer of reassurance that a firm operates within a recognised regulatory framework.
For businesses that are unsure about the new requirements, working with a regulated accountant can help ensure compliance while avoiding unnecessary delays or rejected filings.
Warning Signs to Watch For
Before appointing an accountant or tax adviser, be cautious if:
• They cannot confirm their professional membership
• They ask for tax refunds to be paid to them first
• They avoid providing engagement terms in writing
• Their business frequently changes names or directors
• They are unable to explain who supervises them for anti-money laundering purposes
• They make unrealistic promises about tax refunds or guaranteed savings
A legitimate accountant should be transparent about their qualifications, fees and regulatory status.
How to Check an Accountant’s Credentials
Before engaging any accountant, take a few minutes to verify their credentials.
You can search the public registers maintained by:
• AAT
• ACCA
• ICAEW
You can also check whether a firm is authorised to provide regulated services and ask who supervises them for anti-money laundering compliance.
A regulated accountant should be happy to provide this information.
