It’s calculated based on the property’s Taxable Asset Value (VPT), not the purchase price of the property, and typically ranges from 0.3% to 0.45% for urban properties, and up to 0.8% for rural land.Importantly, the VPT is typically much lower than market value, often one-third to one-quarter of the purchase price – this is why property taxes in Portugal remain low in most casesIMI is paid every year by the property owner registered as of December 31st of the previous year. Rates are set individually by each municipality, so amounts can vary depending on location.For the full legal code and most up-to-date rates, refer to the official Código do IMI – Portal das Finanças.
