In Portugal, the title Contabilista Certificado is a regulated designation governed by the Ordem dos Contabilistas Certificados; only members registered on the OCC public register may sign off accounting and tax compliance filings in that capacity. Statutory auditors hold the separate Revisor Oficial de Contas designation and are governed by the Ordem dos Revisores Oficiais de Contas.

Before you hand over documents, confirm the preparer’s credentials against the official source.

Step 1: Confirm the practitioner holds a valid Contabilista Certificado registration by searching the member register published by the Ordem dos Contabilistas Certificados at occ.pt; active registration is the statutory prerequisite for signing accounting records and tax filings in Portugal.
Step 2: If the engagement involves statutory audit work, verify that the professional is a registered Revisor Oficial de Contas by checking the register maintained by the Ordem dos Revisores Oficiais de Contas at oroc.pt; the ROC credential is distinct from the CC designation and is required for legal audit mandates.
Step 3: Ask the practitioner for their OCC membership number and cross-reference it against the OCC public register to confirm the registration is current and not suspended or revoked before engaging them for tax compliance work.
