Context & Explainers
E‑fatura is the Tax and Customs Authority's online invoice portal (E‑fatura), where taxpayers register and validate invoices so they can claim IRS deductions and benefits. The guidelines in the story note that taxpayers must validate last year’s invoices on the portal by the beginning of March before submitting the annual IRS tax return.
The Portal das Finanças is Portugal's official online tax platform, operated by the Autoridade Tributária e Aduaneira (AT — Tax and Customs Authority). It is where individuals and businesses file tax returns, check tax records, make payments, and manage their fiscal affairs.
Key functions include filing the annual IRS return (Modelo 3), accessing e-invoices (e-fatura), consulting property tax (IMI) records, requesting tax residency certificates, and paying outstanding tax debts. Access requires a NIF (tax identification number) and a password or digital key.
The portal is essential for anyone living or working in Portugal. Residents should be aware that scam messages impersonating the AT are common — always access the portal directly at portaldasfinancas.gov.pt rather than through links in emails or SMS.
