Municipal property tax, known in Portugal by the acronym IMI - Imposto Municipal sobre Imóveis - is calculated on the basis of the Taxable Property Value (VPT shown on the caderneta predial*) of urban and rural buildings located within Portuguese territory.
* "caderneta predial" = unique certificate for each property, as a document identifying the property. Issued by the tax authorities (AT) and also known as a matrix certificate.
IMI rates vary according to the type of property purchased and the municipality in which it is located.
The applicable rate of IMI:
varies between 0.3% and 0.45% of the VPT for urban buildings,
is 0.8% for goods in the "prédios rústicos" category.
IMI must be paid by owners whose names appear on the "caderneta predial" on 31 December of the year to which the tax relates. So, for a purchase made on 27 December 2021, in 2022, the person liable for IMI in 2021 is the person who purchased the property on 27 December.
📅 IMI is an annual tax payable according to the following schedule:
Up to €100: 1 single payment, to be made in May (deadline 31 May) ;
More than €100 and less than or equal to €500: 2 payments, in May and November (deadline 30 November);
More than €500: 3 payments, to be paid in May, August and November.
