IRS tax return filing period begins for 6 million households
The three-month window to submit annual tax returns (declaração de IRS) for 2025 income opens today on the Finance Portal (Portal das Finanças). Taxpayers have until June 30 to file, regardless of whether they are employees, pensioners, or self-employed workers (trabalhadores a recibos verdes). Experts warn that refunds may be lower this year because the Tax Authority (Autoridade Tributária e Aduaneira or AT) adjusted withholding tables mid-year to leave more money in monthly paychecks.
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.
Green receipts (recibos verdes) are the digital invoices used by self-employed workers and freelancers in Portugal to report their earnings. They are managed through the Finance Portal (Portal das Finanças) and are used to calculate annual income tax (IRS) and social security (Segurança Social) obligations.
