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.
IRS tax return filing period begins for 6 million households

Context & Explainers
The Tax Portal (Portal das Finanças) is Portugal's official online service where individuals and businesses access tax records, file returns, and make payments. On 6 February 2026 the Tax and Customs Authority (Autoridade Tributária e Aduaneira or AT) used the portal to warn taxpayers about scam SMS messages falsely demanding payment to 'avoid seizure'; residents should ignore unsolicited payment links and check the portal or contact AT directly.
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.
