Unmasking the shadows: Capitalize on the growing need for crypto compliance

Learn how to expand your service offerings and generate additional revenue while safeguarding against financial crime with crypto-related Enhanced KYT Due Diligence.

Crypto tax accountants operate at the intersection of a rapidly evolving asset class and increasingly stringent regulatory demands. While their primary focus is tax compliance, understanding crypto's inherent money laundering risks is crucial, even before the Sixth Directive on AML/CFT comes into force and can represent a significant revenue stream. Crypto accountants typically charge €10,000-€20,000 for preparing KYT EDD documentation required by their clients’ banks.

Enhanced Due Diligence (EDD), particularly its Know Your Transaction (KYT) components, provides the necessary framework to identify these interconnected illicit activities. 

I. The Dual Challenge: Crypto Tax Evasion and Money Laundering

The failure to accurately report and pay taxes on cryptocurrency investment gains is a significant issue. This often manifests as a blend of offshore tax evasion – utilising foreign-based platforms and offramps to avoid local tax authorities – and more frequently, straightforward income underreporting. The pseudo-anonymous nature of crypto transactions and underregulation of crypto industry could create a false sense of impunity for tax evaders.

However, the risk extends beyond mere tax avoidance. Seemingly compliant tax payments on crypto gains can conceal more serious money laundering operations. For instance:

An individual might report and pay substantial tax on €1 million of declared crypto profit. Yet, a deeper analysis could reveal €1 million in deposits into the same account from unverifiable or suspicious sources. The reported €1 million gain could be artificially manufactured through techniques like wash trading or taking opposite positions on different exchanges.

This creates a facade of legitimacy, obscuring the illicit origin of the remaining funds. Therefore, a singular focus on tax compliance is insufficient; a holistic approach incorporating robust EDD and KYT is essential to detect underlying money laundering.

II. Enhanced Due Diligence and Know Your Transaction: Uncovering the Hidden Flows

Standard KYC/CDD procedures often lack the granularity required to identify the intricate links between crypto tax fraud and money laundering. “The client looked completely normal” we often hear from clients when they discover FinCrime patterns or significant inflows from sanctioned darknet markets in their clients' complex webs of transactions.
Enhanced Due Diligence (EDD) mandates a deeper level of scrutiny, particularly concerning the Source of Wealth (SOW) and Source of Funds (SOF). For crypto tax accountants and the financial institutions they advise/prepare documents for, understanding how clients accumulate their crypto assets and the origin of the specific funds involved in taxable transactions is paramount. Missing walets, complex transaction structures involving high risk off-shore crypto exchanges, and transactions lacking clear economic purpose should trigger heightened scrutiny.

Crucially, Know Your Transaction (KYT) is a vital component of EDD in the crypto space. As detailed in the ChainComply guide on MiCA compliance, KYT involves a detailed analysis of the transaction itself, its context, and its alignment with the client's risk profile and expected behavior. For crypto tax accountants, understanding the KYT aspects within EDD is key to identifying potential money laundering red flags often masked by tax compliance. Moreover, it is also a valuable opportunity to monetize their expertise by charging clients additional fees for preparing the increasingly required KYT-focused EDD documentation for their banks. This includes:

  • Blockchain risky interactions: It is fundamental to utilise blockchain analysis tools to discover clients’ high-risk wallet interactions. These tools allow for identifying high-risk addresses, counterparties (e.g., sanctioned entities, known illicit platforms), and the flow of funds through mixers or tumblers, even if some gains are declared for tax. 
  • Pattern Recognition in Transaction Behavior: Analysing the volume, frequency, and counterparties of crypto transactions can reveal anomalies. Large, rapid movements of funds, particularly to or from high-risk jurisdictions or DeFi protocols with lax AML controls, can indicate layering or integration of illicit proceeds, irrespective of reported tax.
  • Wallet Risk Assessment: Understanding the inherent risks associated with the types of wallets and platforms used by clients is crucial. Transactions involving unhosted wallets or those interacting with unregulated or high-risk exchanges necessitate closer examination.
  • Counterparty Vetting: While tax liability rests with your client, understanding the nature of their significant counterparties in crypto transactions can reveal potential links to illicit activities.
  • Temporal Analysis of Transactions: Examining the timing and sequence of transactions can uncover the sources of wealth creation in time.

All the above can be done using Excel and any of the blockchain analysis tools available on the market. However, the analysis and reporting can take days or weeks.
Tools like ChainComply automate these checks, simplifying source of wealth discovery and standardising reporting. They reduce crypto accountants' EDD work to minutes and make it particularly profitable.

III. Red Flags for Crypto Tax Accountants: Identifying the Money Laundering Link

As crypto tax accountants, be vigilant for the following red flags during your due diligence processes, which may indicate underlying money laundering despite apparent tax compliance:

  • Significant discrepancies between the client's overall crypto transaction volume and the declared taxable gains.
  • Frequent use of privacy-enhancing wallets or mixers in conjunction with reported taxable events.
  • Large transactions with crypto exchanges known for weak AML controls or located in high-risk jurisdictions, even if some gains from these transactions are declared.
  • Complex transaction patterns involving multiple blockchains or DeFi protocols, seemingly designed to obscure the origin of funds, with only a fraction of the activity resulting in reported gains.
  • Sudden and unexplained spikes in crypto transaction activity preceding the withdrawal
  • Reluctance or inability of the client to provide clear documentation for the source of their initial crypto investments (SOW/SOF).
  • Inconsistencies between the client's declared income and the scale of their crypto investments and trading activity.
  • Transactions involving counterparties flagged by blockchain analytics tools as highly associated with illicit activities.

IV. Practical Implications for Crypto Tax Accountants

While you are not yet directly responsible for AML compliance, understanding these red flags and incorporating a degree of transactional awareness into your due diligence can provide significant value to your clients and protect them from potential legal repercussions. This includes:

  • Explaining the consequences of interaction with risky addresses in terms of AML controls at financial institutions
  • Advising clients on the importance of maintaining clear and auditable records of their crypto transactions and the source of their funds.
  • Asking probing questions about the origin of crypto assets and the rationale behind significant transactions
  • Reviewing transaction histories (with the client's consent) for unusual patterns or high-risk counterparties.
  • Recognizing when a client's activities warrant referral to legal counsel or specialized AML compliance professionals. Equipping yourself with the right tools will take you far, but do not forget to collaborate. 

Conclusion: Integrating Transactional Awareness into Crypto Tax Practice

For crypto tax accountants, a nuanced understanding of the interplay between tax evasion and money laundering is no longer optional. By integrating a level of transactional awareness, grounded in the principles of KYT within EDD, you can provide more comprehensive advice to your clients and contribute to a more transparent and secure crypto ecosystem. Recognizing that seemingly compliant tax payments can mask underlying illicit activities is the first step towards identifying and mitigating these complex risks.

And if you can be properly rewarded for doing the right thing, that's a powerful alignment of incentives, isn't it?
