CTIF Belgium: How to Report Suspicious Transactions

In brief

The CTIF (Financial Intelligence Processing Unit) is the Belgian financial intelligence unit that receives suspicious transaction reports from regulated entities. For domiciliation centers, reporting is an absolute legal obligation under penalty of fines up to 5 million euros. When in doubt, report: the law protects you with civil and criminal immunity for any report made in good faith.

Introduction: Reporting Suspicious Transactions, an AML Pillar

The Financial Intelligence Processing Unit (CTIF-CFI) is Belgium's financial intelligence unit responsible for combating money laundering and terrorist financing.

For domiciliation centers, reporting a suspicious transaction to CTIF is an absolute legal obligation under penalty of €5 million fine and imprisonment from 6 months to 5 years.

> ⚠️ Golden rule: When in doubt, report it! CTIF prefers 10 "clean" reports over one unreported laundering operation.

Money Laundering Indicators

Suspicious client behavior:

• ❌ Reluctant to provide KYC info

• ❌ Falsified ID documents

• ❌ Frequent UBO/director changes
