Portugal's annual municipal property tax — calculated on the Valor Patrimonial Tributário (VPT) assessed value of all property owned in Portugal.
IMI — Imposto Municipal sobre Imóveis — is Portugal's annual property tax, equivalent to Spain's IBI or the UK's council tax. It is a local tax administered by the Autoridade Tributária e Aduaneira (AT) and collected by each município. Every owner of Portuguese real estate — resident or non-resident, Portuguese or foreign — pays IMI on each property they own as at 31 December of the tax year.
IMI is calculated as a percentage of the property's Valor Patrimonial Tributário (VPT) — the fiscal assessed value of the property recorded in the Caderneta Predial. The VPT is determined by the AT using a formula that considers factors including the property's usable area, location, age, and quality. The VPT is typically lower than the market value. Municipalities set IMI rates within national bands: urban property (prédio urbano) is taxed at 0.3%–0.45%, while rural property (prédio rústico) is taxed at 0.8%. Lisbon currently charges 0.3%; Porto charges 0.33%.
IMI is billed by the AT and paid in instalments. For annual IMI bills up to €500, one payment is due in April. For bills between €500 and €1,000, two payments are due (April and November). For bills above €1,000, three payments are due (April, July, November). Taxpayers can pay via the AT Portal das Finanças, Multibanco ATM, online banking, or at a post office (CTT).
Certain exemptions and reductions apply. The most significant for expats is the permanent exemption for habitual residence (habitação própria e permanente): properties used as the owner's primary Portuguese residence with a VPT up to €125,000 may qualify for a permanent IMI exemption, provided the owner's annual household income does not exceed €153,300. There is also a temporary 3-year IMI exemption for new first-time buyer properties with VPT up to €125,000.
Non-residents are generally not eligible for the habitual residence exemption. For investment properties or holiday homes, IMI is a recurring annual cost that should be factored into your property investment analysis. Some municipalities apply a surcharge (coeficiente de localização) for central urban areas, increasing the effective VPT and therefore the IMI liability. Always verify the exact IMI amount by requesting the Caderneta Predial and checking the current municipal rate before completing a purchase.
IMI = VPT (Valor Patrimonial Tributário) × municipal rate. The VPT is the fiscal assessed value, typically lower than market value. The municipal rate is set by each câmara municipal within national bands (0.3%–0.45% for urban property). Your annual IMI bill is available via the Portal das Finanças once you have a NIF.
For IMI bills up to €500: one payment in April. For bills €500–€1,000: two payments (April and November). For bills over €1,000: three payments (April, July, and November). You can set up a direct debit via the Portal das Finanças to avoid missed payments.
Yes, if the property is your permanent primary residence in Portugal and has a VPT ≤ €125,000, and your household income is ≤ €153,300, you may qualify for a permanent IMI exemption. There is also a temporary 3-year exemption for first-time buyers. Non-residents and holiday home owners are generally not eligible for these exemptions.
