October 2026 Summaries

Tax filings and business registries may be accurate yet fail to reveal who actually controls a company, particularly in cases involving VAT carousel fraud, successor businesses, nominee directors, layered ownership structures, or entities split to remain below regulatory thresholds. Using Operation Admiral in Portugal as an example, the discussion explains how cross-border investigations can uncover extensive networks of companies and individuals whose relationships are not apparent from isolated records. It argues that investigators need both entity resolution to identify records referring to the same people or businesses and ownership-and-control tracing to examine links among companies, individuals, accounts, filings, and transactions without treating connected entities as a single taxpayer. The piece presents graph-based investigative knowledge layers, such as Neo4j’s platform, as a way to preserve distinct records while making relationships, evidence sources, dates, and uncertainty reviewable, reducing repeated manual work and allowing findings from one investigation to inform later cases while remaining open to revision.
