The Tax and Customs Authority (Autoridade Tributária e Aduaneira or AT) is warning citizens about a rise in fraudulent phone calls, known as vishing, regarding IRS tax returns. Scammers are contacting individuals and asking them to press keys to correct alleged discrepancies in their tax filings. Authorities advise taxpayers to remain vigilant and use only official communication channels.

Context & Explainers

Housing fiscal measures are government tax changes or incentives aimed at the property market — examples include changes to property tax (IMI Imposto Municipal sobre Imóveis), stamp or transfer taxes (IMT Imposto Municipal sobre Transmissões Onerosas de Imóveis) and income‑tax (IRS Imposto sobre o Rendimento das Pessoas Singulares) deductions for renovations or rental incentives. The estimated €200–300 million budgetary cost shows the measures have a meaningful impact on public finances and signals whether the government is prioritising tax relief for homeowners, landlords or construction, which can affect property prices and rental markets that matter to expats.
