Taxpayers have until Tuesday, March 31, to contest the value of expenses recorded by the tax authority for 2024 income. Residents should check the Portal das Finanças to verify that health, education, and general family expenses are correctly listed before the official tax filing period begins on April 1. This is the final opportunity to ensure all tax deductions (deduções à coleta) are accurately applied to the upcoming IRS return.

Context & Explainers
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.
