HMRC’s AML fines have surged by a staggering 177% over the past four years. This sharp increase shows that UK regulators are cracking down harder than ever on money laundering. 

That said, it’s not possible for accountants to dig into every single detail regarding the client they are seeking to work with. So, there’s always a risk of something slipping through and if it does, the consequences can be severe.  

Does this mean accountants are at a dead end or is there a way to spot warning signs early and manage risk effectively?  

Utilising their years of experience in onboarding clients and running AML checks, FigsFlow’s team has prepared this list of five red flags that accountants should keep an eye out for.  

We’ve also included a bonus tip at the end of this article to help you get automatic alerts when one of these red flag appears. 

Sounds good? Let’s dive in. 

1. Reluctance to Provide Information

One of the most telling signs of potential money laundering is when clients exhibit nervous behaviour or show unusual reluctance to comply with standard due diligence procedures. These behaviours can indicate an attempt to avoid scrutiny or conceal information that would otherwise be routine for legitimate businesses.  

These behaviours can include: 

  • Hesitancy to provide identification document or beneficial ownership information  
  • Unusual nervousness about compliance procedures 
  • Requests for unnecessary secrecy or confidentiality 
  • Inconsistent personal information across documents 

These red flags can be spotted through basic observation, common sense and an understanding of human psychology. So, it’s important to train your onboarding and front-line staff to recognise signs of hesitation, defensiveness or inconsistencies. When they do, prompt further questioning and carry out enhanced due diligence 

2. Suspicious Transaction Patterns & Cash Activities

Money launderers often leave distinct footprints in their transaction patterns, which can be detected through careful monitoring and analysis.  

Some of these patterns include: 

  • Large cash deposits or payments without clear business rationale 
  • Rapid movement of funds between accounts 
  • Transactions inconsistent with known business activities 
  • Payment to and from parties with no apparent business relationships 
  • Deposits or payments that are just below reporting thresholds 

These patterns can often be flagged by AML (Anti-Money laundering) software.  These software detect any anomalies in client transactions and automatically trigger alerts. Some platforms even allow accountants to customise thresholds and criteria based on their risk appetite and client risk profile.  

3. Complex Business Structures Without Clear Purpose

While complex business structures aren’t inherently suspicious, they can be used to obscure beneficial ownership and facilitate money laundering. So, it’s important to remain cautious when clients establish multiple shell companies, use nominee directors, or create convoluted ownership arrangements that seem disproportionate to their actual business needs.  

Here are a few things to watch out for: 

  • Complex ownership structures without a clear business purpose 
  • Multiple shell companies or nominee directors involved 
  • Business addresses that don’t match actual operations 
  • Involvement of high-risk jurisdictions without logical commercial reasons 

These setups may be legitimate in some cases, such as for tax planning or international expansion, but they warrant closer scrutiny.  

AML systems can help by flagging entities with links to high-risk jurisdictions or identifying patterns across related accounts. However, detecting suspicious ownership structure often requires manual review and investigative thinking. So, train your compliance and onboarding teams to spot inconsistencies, ask the right questions and escalate concerns. 

4. Financial Inconsistencies & Unexplained Wealth

One of the most significant indicators of potential money laundering is when a client’s financial position doesn’t align with their known sources of income 

This includes: 

  • Lifestyle or spending habits that don’t match declared income 
  • VAT returns that don’t align with actual bank activity 
  • Unexplained wealth or asset acquisition without clear funding sources 
  • Payments from unexpected third parties 

These inconsistencies often indicate that the funds may be coming from undisclosed or potentially illicit sources and can be detected through a combination of financial analysis and automated tools. 

Many client onboarding platforms are equipped to flag mismatches between reported income and actual transaction volumes. These software can help surface the anomalies but actual human judgement is required especially when reviewing documents like VAT returns, bank statements and client disclosures 

5. Documentation & Source of Funds Issues

Poor quality, suspicious or incomplete documentation is another major red flag in identifying potential money laundering. These issues often surface during onboarding or periodic reviews and can indicate attempts to obscure identity, ownership or the origin of the funds. 

Some of the common documentation-related red flags include: 

  • Poor quality or suspicious identification documents (e.g., altered, heavily photocopied or issued from high-risk jurisdictions) 
  • Frequent changes to company details without clear justification 
  • Missing or incomplete beneficial ownership information 
  • Documents from different sources that don’t align or contract each other 

When documentation appears inconsistent or questionable, it’s essential to investigate further. Some AML software can help flag discrepancies in submitted data but detecting poor-quality or suspicious documents requires human judgement
