TINs in Criminal Finance and Fugitives’ Evasion Strategies

VANCOUVER, Canada — In an increasingly regulated financial world, the Taxpayer Identification Number (TIN) has emerged as both the key to uncovering illicit finance and the target of sophisticated manipulation by fugitives and economic criminals. 

As international regulators strengthen their grip through frameworks like FATCA and CRS, the TIN—once a simple tax processing tool—has become a prime weapon in the fight against global criminal finance.

But as governments enhance transparency, criminals adapt. This report examines the use of TINs in criminal finance investigations, the strategies fugitives employ to evade detection, and how law enforcement and advisory firms, such as Amicus International Consulting, are responding to this evolving challenge.

The TIN: A Universal Financial Identifier

A Taxpayer Identification Number (TIN) is a unique number assigned by a country’s tax authority. Globally, it now acts as a universal ID across banking, real estate, corporate ownership, and crypto. 

For law enforcement, TINs are crucial in tracing illicit funds and uncovering cross-border asset trails.

TINs are now collected during:

• Bank account openings
• Real estate acquisitions
• Crypto exchange onboarding
• Business formation and director registration
• Trust and foundation declarations
• Citizenship and residency-by-investment applications

How TINs Aid Law Enforcement

Global tax authorities, anti-money laundering units, and international financial crime task forces rely on TINs to:

• Identify the beneficial owners of shell companies
• Uncover duplicate or fraudulent financial declarations
• Trigger red flags in FATCA and CRS systems
• Link fugitives to assets despite aliases or synthetic IDs
• Trace capital flows into and out of tax havens

By triangulating TINs across jurisdictions, authorities can match a suspect’s activity—even under new names or passports—to past tax and financial footprints.

Case Study: The Ruffo Revival
John Joseph Ruffo disappeared in 1998 after being convicted in a $350 million fraud case. In 2024, a property inquiry in Italy revealed a rental application tied to a U.S. Taxpayer Identification Number (TIN) belonging to a dormant shell company that Ruffo had once owned. 

The case, long thought to be cold, was reopened, suggesting that Ruffo may have reused a historical corporate structure without entirely scrubbing the associated identifiers.

How Criminals Use TINs—Or Avoid Them Entirely

Criminal financiers and fugitives often rely on TIN evasion strategies to avoid detection:

1. TIN Recycling

Using the TINs of deceased individuals or dormant corporations to open accounts and facilitate financial flows.

2. Multiple TIN Identities

Exploiting dual or triple citizenships to hold multiple TINs across jurisdictions—allowing strategic disclosure or non-disclosure depending on the bank’s location.

3. Synthetic TINs

Generating numbers that follow the correct algorithmic format but were never issued. These are especially common in jurisdictions with poor verification controls.

4. TIN-less Transactions

Conducting high-volume activity through systems that don’t yet enforce TIN compliance, such as specific DeFi protocols, prepaid cards, or informal money service businesses (Hawala, Hundi).

Fugitives and Identity Rebirth

Fugitives seeking long-term evasion often undergo legal or illegal identity reconstitution. Central to their success is breaking the digital trail created by their original TIN.

Strategies include:

• Renouncing citizenship to nullify FATCA or CRS tracking
• Acquiring new identities via forged documents or black-market ID bundles
• Using second passports tied to jurisdictions that don’t fully comply with CRS
• Shifting to legal but TIN-light structures, such as foundations or diplomatic appointments

Amicus Insight: Legal Restructuring vs. TIN Manipulation

Amicus services include:

• International TIN audits and discrepancy identification
• CRS/FATCA alignment for dual nationals and HNW individuals
• Trust and foundation setup with jurisdictional TIN consistency

• Mitigation support for clients under audit or regulatory pressure

TINs in Major Criminal Finance Cases

Ruja Ignatova (“The Crypto queen”)

As of 2025, Ignatova remains on Interpol’s most wanted list. Investigators have used TIN-linked crypto exchange records to trace early One Coin wallet activity back to corporate entities controlled by Bulgarian and German TINs she once declared.

Ayitey Ayayee-Amim

The U.S. investment fraud suspect allegedly used multiple offshore entities registered in jurisdictions with lax tax information exchange (TIN) enforcement. However, a 2023 compliance sweep of Caribbean banks found matching TINs used in old IRS filings, reigniting legal action.

The Dimitrion Disappearance

John Michael and Julieanne Dimitrion fled after pleading guilty to fraud in Hawaii. Traces of their U.S. TINs later surfaced during a real estate acquisition in a non-CRS compliant country, alerting investigators to their possible location.

Why TINs Are the Achilles’ Heel of Long-Term Evasion

Even the best aliases eventually falter when TINs remain in the system. Criminal fugitives often make the mistake of:

• Reusing an old TIN in a new application
• Overlapping financial activity under multiple TINs
• Failing to declare a required TIN under FATCA or CRS
• Assuming a second citizenship exempts them from global data sharing

TIN-based audits now use AI to flag such inconsistencies, triggering cascading disclosures, automatic information exchange, and international arrest requests.

The Crypto Conundrum: From Anonymity to Accountability

As crypto regulation tightens, TINs are now required for:

• Exchange account openings
• NFT marketplaces linked to fiat
• Custodial wallet services
• DeFi platforms operating under licensed jurisdictions

Regulatory bodies—including the OECD under CARF—are linking wallet addresses to TINs, allowing backtracking of previously anonymous transactions.

Case Study: A Fugitive’s Wallet Revealed
A former banker wanted in the UK for insider trading attempted to live off crypto in Southeast Asia. When he used a Singaporean wallet (created years earlier under his real name and Tax Identification Number, or TIN) to convert assets into stablecoins, authorities were notified via an Interpol-FATF data exchange. His assets were frozen within 48 hours.

Legal Cooperation: The Net Tightens

TINs are now the centrepiece of legal cooperation treaties, including:

• Mutual Legal Assistance Treaties (MLATs)
• OECD’s Common Transmission System (CTS)
• Interpol Red Notices supported by FATCA/CRS disclosures
• UNODC-sponsored financial tracking task forces
• G20 agreements for digital asset TIN compliance

Courts in Europe, North America, and Asia now accept TIN data as legitimate evidence in both civil and criminal proceedings, accelerating asset seizures, arrests, and repatriation efforts.

Case Study: False TIN Use Leads to Sanctions

In 2024, a Russian national residing in Spain attempted to route funds through a Panamanian shell company using a fake Panamanian Taxpayer Identification Number (TIN). When the receiving institution attempted CRS validation, the TIN failed to match the national database of Panama. 

Spanish authorities were alerted and launched an investigation into money laundering. The subject’s bank accounts and a €1.6 million villa were frozen pending a further outcome.

Amicus Case File: Legal Strategy Before the Knock

A dual citizen of South Africa and the Netherlands, who was under investigation for underreporting foreign income, approached Amicus after being flagged for inconsistencies in CRS filings associated with multiple TINs.

Amicus conducted:

• A TIN consolidation and corrected historical submissions
• Trust restructuring in compliance with OECD guidelines
• Voluntary disclosure through both countries’ revenue services

The result: avoided prosecution, preserved over 90% of assets, and secured future bank access via compliant structuring.

Preparing for the TIN Future

TINs will only grow in importance as more jurisdictions implement:

• Biometric-linked TINs to prevent identity fraud
• TINs for digital wallets and blockchain activity
• TINs tied to visa, passport, and real estate applications
• AI-based pattern detection across TIN-linked institutions

Amicus International urges individuals and firms alike to treat TIN exposure as seriously as credit risk or cybersecurity, as it is now the number one trigger for audits, investigations, and criminal proceedings worldwide.
