The Italian business register, ComUnica and the annual chamber fee
Who must join the Registro delle imprese and how a Comunicazione Unica is filed: the tools, digital signatures now that the paper proxy is gone, protocol numbers, suspensions, changes and deregistration. Then the yearly duties: the PEC digital address of the business and its directors, the penalties, the diritto annuale owed to the chamber of commerce, its deadline and form F24. Two modules with case studies, 2026 rules.
