Need to file or update the RCBE declaration? Law 89/2017, Article 3 is where it starts.

We file initial RCBE declarations, updates and annual confirmations for Portuguese companies with foreign owners, and map the ownership chain so the beneficial owner is identified correctly. Fixed fee, done in English.

Unofficial English translation prepared by BCA Portugal for reference. Only the Portuguese text published in the Diário da República has legal force. Editorial notes are ours and are not part of the statute.
