Buying a property in Portugal creates two different kinds of costs: purchase-day taxes and transaction costs<\/strong>, and ongoing ownership costs<\/strong>. The main taxes newcomers encounter are IMT (Imposto Municipal sobre as Transmiss\u00f5es Onerosas de Im\u00f3veis<\/em>), stamp duty (Imposto do Selo<\/em>), annual IMI and, for higher-value portfolios, AIMI. This guide explains what each one does and, importantly, where you actually go to declare and pay it.<\/p>\n

IMT: the property transfer tax<\/h2>\n

IMT is normally paid by the buyer when Portuguese real estate is acquired for value. The taxable amount is generally the higher of the purchase\/contract value and the property’s VPT (Valor Patrimonial Tribut\u00e1rio)<\/strong>. The rate then depends on the type of property, its use, value and, under current 2026 rules, in some cases the buyer’s residence position. The authoritative starting point is Finan\u00e7as \u2014 Compra da casa (IMT e IS)<\/a>.<\/p>\n

How progressive IMT actually works<\/h2>\n

For housing categories that use progressive bands, do not simply multiply the entire price by the highest marginal percentage shown in the table. The IMT table has marginal and average-rate mechanics. In practice, use the current official table\/calculation rather than estimating from a headline percentage. Article 17 of the C\u00f3digo do IMT<\/a> contains the current rates.<\/p>\n

For 2026 on the mainland, ordinary own-and-permanent-home purchases start with a 0% band up to \u20ac106,346 and then move through progressive bands; higher values eventually move to single rates. Other housing has a different table. Rural property is generally taxed at 5%, while other urban property\/other taxable acquisitions are generally 6.5%. Always classify the property and intended use correctly before calculating.<\/p>\n

Important 2026 rule for non-resident buyers<\/h2>\n

Portugal changed the IMT rules in 2026. Article 17 now generally applies a 7.5% rate to a non-resident’s acquisition of urban residential property<\/strong>, without the ordinary reduction\/exemption, subject to statutory exceptions. Those exceptions include a buyer who becomes Portuguese tax resident within two years and qualifying affordable residential letting; the law provides a route to request cancellation\/refund of the difference where the later conditions are met. This is a major reason not to rely on an older online IMT calculator if you are buying while non-resident.<\/p>\n

IMT Jovem \/ first-home relief for buyers aged 35 or under<\/h2>\n

There is enhanced IMT relief for a qualifying first acquisition of an urban home for the buyer’s own permanent residence by a person aged 35 or under who meets the statutory conditions. Current Article 9 excludes, among other cases, a buyer who owns or owned a residential urban property (or a qualifying partial right in one) at the time of purchase or during the previous three years. Where two people buy together, eligibility is assessed individually, so one buyer may qualify while the other does not. Check the current gov.pt IMT exemption service<\/a> and Finan\u00e7as before completion.<\/p>\n

Where do I go to declare and pay IMT?<\/h2>\n

You deal with Autoridade Tribut\u00e1ria \/ Finan\u00e7as, not the C\u00e2mara Municipal.<\/strong> Despite the word \u201cMunicipal\u201d in IMT, the practical declaration and payment process is through the Portuguese tax authority.<\/p>\n
