Portugal Property Tax 2026: IMT, IMI & Capital Gains

It is mid-morning at the notário's office in Lagos, and the conveyancing is almost done. The clerk slides a document across the table: the IMT assessment — Portugal's Imposto Municipal sobre as Transmissões, or property transfer tax — calculated on the agreed purchase price of a villa in the hills above the Meia Praia. For a non-resident buyer completing in 2026, the figure is unambiguous: a flat 7.5 per cent on the purchase price. On a €900,000 property, that is €67,500 before stamp duty, legal fees, or notarial costs. The buyer has done some research, but not enough of it. They had expected something lower — a colleague who completed the previous year had paid less. What changed, and why, is the first question any serious buyer of Portuguese property now needs to answer before they make an offer.

Portugal's property tax landscape shifted in several material respects in 2026. A new flat IMT rate replaced the old progressive scale for non-resident buyers. The Non-Habitual Resident regime — the NHR — that had attracted tens of thousands of international buyers and retirees over the previous decade closed at the end of 2023, replaced by a narrower instrument that excludes passive investors and second-home buyers entirely. And in January 2026, a new double taxation treaty between the United Kingdom and Portugal came into force, replacing a framework that dated to 1968. Understanding how these changes interact is essential before any offer is made. This guide works through each element in turn, from acquisition costs to annual holding taxes to exit, and sets out where co-ownership changes the picture for a buyer — bearing in mind that for a co-owner, how tax works depends on the country and the home's legal set-up, which our partner explains before you buy.

Buying Into Portugal: IMT, Stamp Duty and the 2026 Rate Change

Until 2026, Portugal's IMT operated on a progressive scale for residential purchases. A non-resident buying a property priced at €600,000 paid a blended rate that worked out to roughly 5.5 to 6 per cent of the purchase price in practice; at €900,000, the effective rate approached 6.5 per cent. The Construir Portugal housing package, passed by the Portuguese parliament in February 2026, replaced this graduated structure entirely for non-resident buyers: a single flat rate of 7.5 per cent now applies to all residential property purchases by non-residents, regardless of price. For lower-value properties, the change is relatively modest; for higher-value purchases above €800,000, it represents a meaningful increase in acquisition cost. At €1 million, a non-resident buyer now pays €75,000 in IMT alone — roughly €15,000 more than under the previous progressive scale at that price point.

Stamp duty — Imposto do Selo — is charged at a flat 0.8 per cent of the purchase price and applies to all buyers regardless of residency status. Legal fees, notarial costs, and land registry charges typically add a further 1 to 1.5 per cent of purchase price. A buyer's total transaction costs on a €1 million Portuguese property in 2026 therefore run to approximately 9.5 to 10 per cent of the purchase price — a figure that needs to be factored in at the offer stage, not at the notário's desk. Understanding the full acquisition cost structure, and planning for it, is one of the first practical steps in evaluating any Portuguese property transaction. Our buying FAQs set out how these costs are structured and shared within a co-ownership transaction.

For co-ownership buyers, the IMT picture is more nuanced and depends on the home's legal set-up and the applicable Portuguese tax rules. Portuguese law provides general rules for company purchases of residential property, and the way a particular home is set up can affect both the applicable IMT rate and the subsequent AIMI treatment. This is one of several reasons why independent legal and tax advice is essential before completing on any Portuguese property, whether in full ownership or through a shared structure. The general tax principles described in this guide apply; the specific numbers in any given transaction will depend on the structure and require professional verification.

Annual Holding Costs: IMI, AIMI and the Co-Ownership Arithmetic

Once a property is acquired, two annual taxes apply. The first is IMI — Imposto Municipal sobre Imóveis, Portugal's municipal property tax, equivalent in structure to France's taxe foncière or Italy's IMU. IMI is levied on the property's VPT, or valor patrimonial tributário: the cadastral value assigned by the tax authority, which in most cases runs significantly below current market value, particularly in the Algarve and coastal Comporta areas where price appreciation over the past decade has considerably outpaced reassessment cycles. Municipal rates for urban properties typically range from 0.3 to 0.45 per cent of VPT, with Lisbon, Porto, and most Algarve municipalities at or near the lower end of that band. On a property with a VPT of €400,000 — which might have a current market value of €900,000 or more — annual IMI at 0.3 per cent amounts to €1,200. By European standards for prime property, this is a modest recurring charge.

The second annual charge is AIMI — Adicional ao IMI, an additional tax levied on owners whose combined Portuguese residential property VPT exceeds certain thresholds. For individual owners, AIMI is charged at 0.7 per cent on VPT between €600,000 and €1 million, 1 per cent between €1 million and €2 million, and 1.5 per cent above €2 million. A non-resident individual who owns a Portuguese villa with a VPT of €800,000 therefore pays €1,400 in AIMI annually — 0.7 per cent on the €200,000 excess above the €600,000 threshold — in addition to IMI. Married couples filing jointly benefit from a doubled threshold of €1.2 million before AIMI applies.

For properties held through a corporate vehicle, the AIMI rate structure is different, and for higher-value properties, potentially more favourable. Companies pay AIMI at a flat rate of 0.4 per cent on the full VPT of all Portuguese residential properties they hold, with no individual threshold exemption. Whether this rate produces a lower or higher AIMI bill than individual ownership depends on the VPT of the specific property: for VPTs above approximately €700,000 — a range that encompasses most quality Algarve villas and Comporta houses in the current market — the corporate rate of 0.4 per cent is likely to produce a lower annual AIMI charge than the progressive individual rates. Whether this applies to a given co-owned home depends on its legal set-up, which our partner explains before you buy.

For co-owners, IMI and any AIMI on the home are shared running costs, allocated proportionally across the eight owners. A one-eighth share means one-eighth of the annual tax bill — alongside one-eighth of insurance, maintenance, management fees, pool and garden upkeep, and all other running costs. For a quality villa in the Algarve's Golden Triangle with combined IMI and AIMI of, say, €4,800 per year, a single co-owner's annual tax contribution amounts to €600. That figure, modest by any measure, sits within an annual cost structure that the co-ownership model makes tractable in a way that full individual ownership rarely does. A detailed breakdown of how costs are structured and shared is available in our how it works guide.

Capital Gains: The 2023 Reform That Levelled the Field for Foreign Sellers

For much of the past two decades, selling Portuguese property as a non-resident meant paying tax on a fundamentally different basis than a resident seller. Until the end of 2022, non-residents paid a flat 28 per cent on 100 per cent of the net gain — while Portuguese tax residents benefited from a 50 per cent exclusion, paying tax only on half their gain at progressive marginal rates. A sequence of rulings from the European Court of Justice found this differential treatment discriminatory, and Portugal legislated a correction effective 1 January 2023. Non-residents selling Portuguese property now receive the same 50 per cent exclusion as residents: only half the net gain enters the tax calculation, with the applicable marginal rate determined by the seller's income level in their country of residence — broadly between 12.5 and 48 per cent for higher-income sellers. For most sellers, the effective rate on the total gain falls somewhere between 6 and 24 per cent — materially lower than the old flat-rate regime.

Two further reliefs are worth noting. Properties acquired before 1 January 1989 are entirely exempt from Portuguese capital gains tax on sale. And a reinvestment relief exists for sellers whose property constitutes their primary residence: gains reinvested in a qualifying replacement primary residence within the applicable period can be sheltered from tax. This relief is less directly relevant for second-home buyers and co-ownership structures, but it illustrates the general direction of Portuguese capital gains policy — increasingly aligned with broader European norms, and considerably more rational for international sellers than the pre-2023 system. The broader capital gains picture for fractional property owners is covered in detail in our guide to capital gains tax on co-owned property.

For British buyers and sellers, the picture changed further on 20 January 2026, when a new UK-Portugal Double Taxation Convention came into force, replacing a treaty that had governed cross-border taxation between the two countries since 1968. Both countries retain the right to tax gains on Portuguese property — meaning a UK resident who sells a Portuguese property will owe tax in Portugal on the gain under the 50 per cent exclusion rules described above. Crucially, however, under the new treaty, UK sellers can offset Portuguese capital gains tax paid against their UK Capital Gains Tax liability on the same gain, eliminating the risk of double taxation that had applied — imperfectly, with some residual friction — under the older framework. For British co-owners, exactly how this offset applies on exit depends on the home's legal set-up, which our partner explains before you buy; we recommend independent advice on both the timing and the quantum of any UK CGT liability.

The End of NHR and What the IFICI Replacement Really Means for Property Buyers

For most of the 2010s and into the early 2020s, Portugal's Non-Habitual Resident regime — the NHR — was one of the primary draws for international buyers relocating to Portugal or acquiring primary residences there. Under NHR, qualifying tax residents could access a flat 20 per cent tax rate on Portuguese-sourced professional income, exemptions or concessionary rates on most foreign income, and a 10-year window of preferential personal tax treatment. For property buyers who intended to move to Portugal, or at least establish tax residency there, the NHR was a powerful financial incentive that overlaid the ordinary property tax picture with a significant personal income tax advantage. The regime was closed to new applicants after 31 December 2023, with a grandfathering arrangement for those who had already applied or established qualifying residency before that date.

Its replacement — the IFICI regime, officially the Incentivo Fiscal à Investigação Científica e Inovação — is a considerably narrower instrument. IFICI provides a flat 20 per cent tax rate on eligible Portuguese-source income for a 10-year period, but eligibility is tightly restricted to individuals working in qualifying sectors: scientific research, technology, healthcare, renewable energy, and certified innovation start-ups. Retirees, passive investors, and second-home buyers who do not hold a qualifying Portuguese employment or self-employment arrangement are not eligible. The regime is an instrument of economic policy designed to attract skilled workers in strategically identified sectors — not a general tax incentive for international property buyers, as the NHR had effectively become.

For buyers considering a co-ownership share in a Portuguese property — whether in the Algarve, in Comporta, or elsewhere along the coast — the closure of NHR and the narrowness of IFICI have limited direct relevance. Property-level taxation in Portugal — IMT, IMI, AIMI, capital gains — is determined by the nature of the transaction and the ownership structure, not by the buyer's personal tax residency status or eligibility for any incentive regime. A non-resident buyer who never had any connection to NHR pays the same IMT, IMI, and CGT as a buyer who had held NHR status. The practical lesson is simply this: do not structure a Portuguese property acquisition around access to a personal tax incentive regime. Structure it around the property, the ownership vehicle, the quality of the location, and the long-term capital position. Those fundamentals have not changed.

What Co-Ownership Means for Tax in Portugal

With co-ownership, you own a real share of the home — an eighth, a quarter — not a right to use it. You can sell it, pass it on to your heirs, and it rises and falls in value with the house. The legal set-up is arranged by our partner for each home and walked through with you before you buy, and the arrangement is governed by a co-ownership agreement that sets out scheduling rights, cost-sharing obligations, maintenance standards, and the mechanism for buying or selling shares over time.

How tax works for a co-owner depends on the country and the home's legal set-up, which our partner explains before you buy; we recommend independent advice. Succession deserves particular attention. Portuguese law imposes forced heirship obligations on individual property owners, requiring that a defined portion of the estate pass to a spouse and direct descendants regardless of the terms of any will. How these rules apply to your share depends on the home's legal set-up and your own circumstances, so it is worth raising with your adviser early. For buyers whose planning concerns extend to the next generation, this distinction is not a minor detail. Our guide to inheritance and estate planning for fractional property owners covers this dimension in full, across the main European markets.

Exit works differently too. Selling a property held directly by an individual in Portugal requires a full conveyancing transaction — notarial deed, land registry transfer, IMT payable by the new buyer, and all the associated legal and administrative work that can extend a transaction timeline considerably. A co-owner's share is resold through our partner's resale process, without having to sell the whole house. The capital gains treatment of a share disposal may also differ from the treatment of a direct property disposal in some circumstances, depending on the home's legal set-up and the applicable double taxation treaty between Portugal and the seller's country of residence. This is an area where professional tax advice is essential before any exit, but it is worth understanding as a dimension of the ownership model from the outset. The broader framework for co-ownership exits is covered in our buying FAQs.

For day-to-day tax administration, co-owners are relieved of direct engagement with the Portuguese tax system. The management company handles IMI and AIMI assessments, ensures that the property's caderneta predial — its land registry record — is correctly maintained, and manages any tax compliance obligations associated with the property's use. Each co-owner's proportional share of all costs is itemised in the annual account. The co-owner's Portuguese tax exposure is, in effect, managed on their behalf — one of the less-discussed but practically significant advantages of the co-ownership model over the full individual ownership alternative, particularly for buyers who are not Portuguese tax residents and have limited familiarity with the local tax administration system.

Portugal's Tax Position in a European Context

Viewed comparatively, Portugal's annual property holding costs remain among the lowest of the major European second-home markets for non-resident buyers. France's taxe foncière — particularly in prime Riviera or Breton coastal locations — can run to several times the IMI equivalent on a comparable-value property; Italy's IMU for non-primary-residence owners is assessed at rates that municipalities have progressively increased; Spain's IBI system is analogous to IMI but is frequently combined in coastal municipalities with surcharges and non-resident income imputation charges that increase the annual burden. Against this backdrop, Portugal's combination of low IMI rates, a corporate AIMI rate of 0.4 per cent, and VPT assessments that generally trail market values by a meaningful margin keeps annual holding costs comparatively modest. A fuller comparison across European markets is available in our country-by-country property tax guide for co-owners.

The acquisition cost picture has shifted upward for non-residents with the 2026 IMT change, but the capital gains treatment has improved substantially since the 2023 legislative reform. For buyers entering the Portuguese market today — particularly those targeting the Algarve's Golden Triangle or the Atlantic pine-forest coast around Comporta, where price appreciation over the past five years has been among the strongest in Southern Europe — the relevant question is not whether the tax system is welcoming, but whether the entry price and the long-term capital trajectory justify the upfront acquisition cost. In both those markets, the evidence points in one direction. The Algarve Golden Triangle's prime villa values have risen by more than 60 per cent over the past decade; Comporta's market, structurally constrained by planning restrictions across a protected Atlantic coastal zone, has accelerated sharply as international demand from the United Kingdom, the United States, and Brazil has grown faster than available inventory. Our posts on the Algarve Golden Triangle and the Comporta ownership experience set out the market case in full.

The Case for Co-Ownership in Portugal's Tax Landscape

Portugal's tax regime for property buyers in 2026 is more demanding at the point of acquisition than it was five years ago, more equitable at the point of sale, and largely unchanged in annual holding costs. For buyers arriving with expectations shaped by the NHR era or by the pre-2026 IMT scale, the current landscape requires recalibration. For buyers thinking in terms of the property itself — its location, its quality, the number of weeks of genuine use it will deliver per year, and its long-term capital position — the tax picture is manageable and, through the right ownership structure, genuinely efficient.

Co-ownership addresses several of the most significant friction points in the Portuguese system. It hands day-to-day tax administration to the management company. It means a co-owner who wants to move on sells a share through our partner's resale process rather than a whole house. And it spreads the acquisition cost — including the 7.5 per cent IMT that now represents the largest single upfront charge for non-resident buyers — across eight co-owners, each of whom acquires a real one-eighth share in a property they could not realistically access individually at the same quality level in the same market. A one-eighth share in a quality Algarve or Comporta property at current pricing requires an entry investment of approximately €150,000 to €200,000 per share, including a proportional contribution to acquisition costs. That figure delivers 44 to 45 days of annual usage in a property that is fully managed, maintained to a defined standard, and legally structured for the long term. No Portuguese tax filings to navigate directly. No property manager to appoint. No annual IMI assessment letter to decipher. An annual cost bill at one-eighth of whatever the property's accounts show. That is a different proposition from full individual ownership — and in the current Portuguese market, for most international second-home buyers, it is the more rational one.

Portugal has spent the past decade building one of Europe's most compelling second-home markets: climate, infrastructure, food, relative value against comparable Mediterranean destinations, and a stability of character that the best-known resort areas preserve remarkably well. The tax adjustments of 2026 do not diminish that case — they simply require buyers to enter with clear information rather than outdated assumptions. The opportunity in the Algarve, in Comporta, and along Portugal's Atlantic and southern coasts is real, evidenced, and structurally sound. The buyers who navigate it most effectively will be those who understand both the numbers and the ownership structure. This is precisely what a co-ownership model is designed to provide: access to the best of the destination, with none of the administrative complexity of full ownership in a foreign jurisdiction, and a tax profile that — held properly — is considerably more favourable than it first appears.
