Taxpayers have until the end of today to dispute expense values on the Finance Portal (Portal das Finanças) before the income tax (IRS) filing period begins on Wednesday. The President of the Republic also approved the expansion of the automatic tax return (declaração automática) to include more young taxpayers under the revised Youth IRS (IRS Jovem) rules. Experts warn that changes to withholding tax (retenção na fonte) tables last year may result in smaller refunds for many households.
IRS filing begins tomorrow as expense dispute deadline ends
Tuesday, 31 March 2026AI summary
Context & Explainers
IRS Jovem is a tax benefit that provides a partial exemption on employment income for young workers aged 18 to 26 during their first five years of work. It helps young professionals retain more of their earnings by reducing their income tax (Imposto sobre o Rendimento de Pessoas Singulares) liability. As of 2024, these taxpayers are eligible for the automatic tax return system, simplifying the annual filing process.
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.
