eCAC is the Receita Federal’s virtual service center (Centro Virtual de Atendimento ao Contribuinte), a secure online portal where taxpayers check their tax status, filings and debts, issue certificates and receive official notices. Companies operating in Brazil, including those with foreign owners, need controlled access to it.
What can you do in eCAC?
- Check pending tax items and filing status
- Issue tax clearance certificates
- Reissue payment slips and request installment plans
- Access filings such as DCTFWeb
- Grant electronic power of attorney to accountants or representatives
- Read messages in the electronic mailbox (Caixa Postal)
How do companies get access?
Companies access with their digital certificate (eCNPJ) or through a representative authorized by electronic power of attorney. Individuals access with a gov.br account at silver or gold level, or with a digital certificate. For a foreign owned company, the legal representative or the accounting provider usually holds the operational access.
Why does it matter for foreign owners?
- Official notices sent to the mailbox can count as valid notification, with deadlines that start running even if nobody reads them
- Tax clearance certificates are often required for contracts, bank procedures and public tenders
- Pending items can block certificates and lead to fines
Who should hold the access?
Avoid depending on a single employee. Define roles, revoke access when someone leaves, and use electronic power of attorney for your accounting provider instead of sharing certificates.
Frequently asked questions
Is eCAC only for Brazilian citizens? No. Any taxpayer registered in Brazil can use it, including companies with foreign owners, through the company’s certificate or an authorized representative.
Can my accountant access it for me? Yes, with an electronic power of attorney granted through eCAC.
What if nobody has checked it for months? Review it right away. Unread notices and pending items can already carry deadlines and penalties.
