Real estate taxes in Portugal 2026: IMT, IMI, stamp duty, and the sale tax

Three points where the state takes tax

To avoid getting confused by abbreviations, keep a simple logic in mind: real estate taxes in Portugal arise at three different points in a property's life, and they shouldn't be mixed up.

• At the moment of purchase- one-off taxes: IMT (the municipal real estate transfer tax) and Imposto de Selo (stamp duty). They're paid once, before signing the notarial deed.
• Every year of ownership- the regular IMI (municipal property tax), and for expensive portfolios - the AIMI surcharge. These taxes arrive annually while you're the owner.
• At the moment of sale- capital gains tax (mais-valias) on the difference between the purchase price and the sale price.

This article follows the same logic: first we break down entry taxes, then annual ones, then the exit tax and ways to legally reduce it. If you're just eyeing the market, start with our general breakdown,how to buy real estate in Portugal- it covers the whole process from choosing a property to the deal. Here we focus exactly on the fiscal side.

An important caveat: IMT rates and thresholds are annually indexed by the state budget, and each municipality sets its own IMI rate within a set corridor. So the final figure is always calculated for a specific property and city.

IMT - the real estate transfer tax at purchase

IMT (Imposto Municipal sobre as Transmissoes Onerosas de Imoveis) is a one-off municipal tax the buyer pays when ownership transfers. It's calculated from the greater of two values: the deal price or the property's tax value (VPT). This is the key and largest of the one-off taxes.

The rate's logic depends on who's buying and for what:

• A resident buying a main homepays under a progressive scale. Inexpensive housing is fully exempt, then the rate rises in brackets. For 2026, full exemption applies to urban housing valued up to approximately €106,346.
• Housing not for permanent residence(a second home, a rental investment) is taxed on its own, slightly higher progressive scale.
• Non-residentsfrom 2026 pay a simplified rate - a flat 7.5% on the residential real estate price, with no progression.
• Commercial real estate and building plots- around 6.5%, rural plots (predios rusticos) - 5%.

The progressive scale is set up so the top bracket for housing gives an effective rate of around 6-7.5%, and on expensive properties the rate approaches the ceiling. So a rough benchmark for budgeting a purchase is to allocate around 6-8% of the housing value for IMT. See the exact brackets in the table below.

The progressive IMT scale for 2026: brackets and rates

IMT progression for housing works on the income tax principle: each bracket is taxed at its own rate, there's a deductible part, so the real (effective) rate is below the maximum. Below are approximate 2026 brackets for urban housing used as a main and permanent residence. The figures are indexed by the budget annually by around 2%, so they're checked against the date before a deal.

Note the "ceiling effect": on the most expensive properties, the rate doesn't grow beyond 8%, but switches to a flat 6% on the whole sum. For housing not for permanent residence, a similar but shifted scale applies. Young buyers under 35 on their first main home purchase are entitled to a separate IMT Jovem exemption - full up to approximately €330,539 and reduced up to double the threshold. These benefits are available to Portuguese tax residents and don't apply to the non-resident 7.5% flat rate.

Imposto de Selo - stamp duty

The second one-off purchase tax is the stamp duty, Imposto de Selo. It's simple and predictable:0.8% of the greater of the two values - the deal price or the VPT tax value. Unlike IMT, the stamp duty has neither progression nor value-based exemptions - it's paid on any deal, by both resident and non-resident, on housing and commercial property.

A separate story - if the purchase involves a Portuguese mortgage. Then a stamp duty is added on the loan amount too:

• 0,6%- for loans over five years;
• 0,5%- for shorter-term loans.

That is, in a mortgage deal, stamp duty arises twice: once on the property value (0.8%) and once on the loan principal (0.5-0.6%). This needs budgeting in advance, because the bank and notary will withhold the duty at processing.

In the deal's overall budget, stamp duty isn't the main item, but it's not pocket change either: on a €400,000 property this is €3,200 just for the real estate portion. Together with IMT and notary-registration expenses, the one-off purchase costs add up to a noticeable sum, better calculated before making the deposit. A detailed breakdown of costs on specific markets is in our articles onbuying real estate in Lisbonand real estate in Porto.

IMI - the annual municipal tax

After the deal closes, the owner's annual obligations begin with IMI (Imposto Municipal sobre Imoveis). This is the main regular real estate tax, an analogue of our property tax. All real estate owners in Portugal pay it - residents and non-residents, individuals and companies alike.

IMI is calculated not from the market price and not the purchase price, but the property's tax value - VPT (Valor Patrimonial Tributario). This value is determined by the tax authority using a formula including area, type, age, location, and the base construction cost. VPT is generally noticeably below the market price, which works in the owner's favor.

Rates for 2026:

• Urban real estate- from 0.3% to 0.45% of VPT. Each municipality sets the exact rate within this corridor itself.
• Rural real estate- a fixed 0.8% of VPT.

IMI is paid in the year following the ownership year: the bill generally arrives in spring, and for a sum above a certain threshold it can be split into several installments (usually May, August, and November). For a family's main and permanent home with a low VPT, a temporary IMI exemption is available - generally up to three years, if conditions are met. Municipalities give large families discounts on the rate.

AIMI - a surcharge on expensive real estate

On top of the regular IMI, Portugal takes an additional tax on large real estate portfolios - AIMI (Adicional ao Imposto Municipal sobre Imoveis). This is the closest analogue to a wealth tax, but it concerns only real estate, not all assets. And importantly - the threshold is counted not per single property, but by the sum of tax value (VPT) of the owner's entire residential property in Portugal.

How the calculation works for individuals:

• From the total VPT of all residential real estate is deducteda €600,000 tax-free threshold per person. For spouses filing jointly, the deduction doubles to1 200 000 €.
• On the amount above the threshold is taken0,7%.
• On the value portion above€1 millionthe rate -1%.
• On the part above€2 million - 1,5%.

For company owners the logic is stricter: a flat 0.4% on the full VPT with no right to the €600,000 deduction, and with personal use - up to 0.7%. So a "villa on an offshore company" scheme in Portugal doesn't save on AIMI.

The practical takeaway: AIMI is a wealthy buyer's tax. If you're taking one apartment for €300-400 thousand, it doesn't concern you. If you're building a portfolio of several properties or buying an expensive house, AIMI needs calculating in advance, and it's often more advantageous to hold real estate under individuals with separate thresholds.

Capital gains tax on sale

When an owner sells real estate for more than they bought it, the capital gains tax - mais-valias - arises. Not the full deal amount is taxed, only the profit: the difference between the sale price and the purchase price, adjusted for the inflation coefficient and reduced by documentarily confirmed expenses.

What expenses are deducted from the gain:

• the IMT and stamp duty paid at purchase;
• notary and registration expenses;
• improvement and renovation costs over the last 12 years (with receipts and invoices);
• agency commission on sale.

Next a key rule applies, uniform since 2023 for both residents and non-residents:only 50% of the gain is included in the taxable base. This 50% is added to the person's other income and taxed under the progressive income tax (IRS) scale - from 13.25% to 48% for 2026. That is, the effective rate for most sellers comes out around 6.5-24% of the gain, depending on the profit size and other income.

Sellers from blacklisted tax-haven jurisdictions stand apart: the softer rule doesn't work for them - all 100% of the gain is taxed at a 35% rate. It's important to plan the ownership structure in advance, especially for owners from the CIS.

How the tax on sale is calculated: an example

To make the figures tangible, let's break down a hypothetical example of a non-resident selling an apartment. Say the property was bought for €300,000, sold a few years later for €400,000, and purchase and renovation expenses were €30,000.

You can see that thanks to the "50% in the base" rule, the tax is taken not on the full €70,000 profit, but only half. The final amount depends on which IRS scale brackets this income falls into together with the seller's other income for the year. This is a simplified illustration, not an exact calculation: the real figure is always determined by the return, accounting for the inflation coefficient and the full set of expenses.

How to legally reduce the tax on sale

The capital gains tax has legal reduction mechanisms - but almost all are tied to main and permanent home status. The main tool - the reinvestment exemption (isencao por reinvestimento).

The essence is this: if you sell housing that was your main and permanent residence, and invest the proceeds (net of the loan repaid on that property) into buying or building another main home, the gain is exempt from tax. 2026 conditions:

• Reinvestment deadlines- within a window of 24 months before the deal and up to 36 months after it.
• Housing status- the sold property had to be the family's main home for at least the last 12 months, and the new property must become the main home within 12 months.
• Geography- the new housing can be not just in Portugal, but any EU or EEA country (Norway, Iceland, Liechtenstein).
• Declaration- the intent to reinvest is declared in the IRS return for the sale year.

If only part of the proceeds is reinvested, the exemption applies proportionally: invested 80% - 80% of the gain is exempt. There's also a separate benefit for people 65+ and pensioners - reinvesting the proceeds into a pension product. All these mechanisms require careful processing, or the exemption won't be confirmed.

Rental income tax

If real estate is bought for letting, a rental income tax is added to the taxes on the property itself. This is important for those considering the purchase as a passive-income investment to factor in.

An individual's long-term rental income is taxed under the general rule at a flat rate of25%of net income (after deducting expenses - IMI, insurance, renovation, loan interest). There's a pleasant incentive: the longer the rental contract, the lower the rate. Long-term contracts give a reduction - down to single-digit figures for contracts spanning many years, which the state specifically encourages for a stable rental market.

Alternatively, rental income can be included in the general progressive IRS scale (from 13.25% to 48%) - this makes sense if total income is low and falls into the lower brackets.

A separate regime - short-term tourist rental (Alojamento Local). It has its own taxation system with coefficients, licensing, and municipal restrictions, and in a number of overheated-market zones new licenses are restricted. For an owner counting on living off Airbnb income, this is a critical point - the rules need checking for the specific address. We break down the link between taxes and residence permits and investment routes separately, in our guide onPortugal's tax regimes and NHR.

Common mistakes in real estate taxes: an expert's view

From practice we see that Portugal real estate buyers and sellers are let down not by complex schemes, but the same recurring oversights. Let's break them down so you don't overpay.

• Didn't budget for IMT and stamp duty.On top of the property price, 7-9% in one-off taxes and expenses genuinely add up. They need calculating before the deposit, not after.
• Registered an expensive house to a company for "optimization".For AIMI this is often a loss: the company pays with no €600,000 deduction, and with personal use the rate is even higher.
• Didn't keep renovation receipts.On sale, improvements over 12 years are deducted from the gain - but only with documents. No invoices - no deduction.
• Missed the reinvestment window.The main home exemption works strictly within the 24/36-month deadlines and with a correct declaration - miss it, and the tax can no longer be cancelled.
• Forgot about tax haven status.Sellers from blacklisted jurisdictions lose the "50% in the base" rule and pay 35% on the full profit. It's important to check the ownership structure in advance.

Real estate taxes forgive a lot, but don't forgive haste and lost documents. The sooner the buying and exit strategy is built, the smaller the final bill.

Bottom line: how much ownership really costs

If you put it all together, the picture is this. At entry, the buyer spends a noticeable markup on taxes: IMT (a flat 7.5% for a non-resident, progressive for a resident with a main home) plus 0.8% stamp duty, and with a mortgage - another 0.5-0.6% on the loan. These are one-off costs important to calculate before the deal.

During the ownership period, the burden is more modest: annual IMI of 0.3-0.45% of the tax value (generally below market), and only for expensive properties is AIMI added. At exit, tax is taken on only half the gain and under a progressive scale, and when buying a new main home, the gain can be exempted entirely.

The main takeaway: Portugal isn't a country with predatory real estate taxes, but also not a place to buy "by eye". The final amount depends heavily on status, property type, and smart use of benefits. We break down specific markets and their costs in our articles onreal estate in the Algarveand real estate in Lisbon. Current rates and thresholds should always be checked on the official portal ofPortugal's government services (gov.pt), since the budget indexes the figures annually.

Resident or non-resident: the tax difference

The word "resident" comes up constantly in Portuguese taxes, and both rates and benefits depend on it. Let's break down who's who and what this changes.

A person becomes a Portuguese tax resident if they spend more than 183 days a year in the country or have permanent housing here they consider their home. A resident pays taxes on worldwide income, a non-resident - only on income from Portuguese sources.

What changes in practice for real estate:

• IMT at purchase.A resident buying a main home goes through a progressive scale with an exemption for inexpensive properties and access to the youth benefit. A non-resident from 2026 pays a flat 7.5% on housing - simpler, but with no benefits.
• Tax at sale.The "50% of the gain in the base" rule now applies equally to residents and non-residents. The difference is in the IRS scale that then taxes this income.
• Reinvestment exemptionavailable on selling a main home, and it's tied to the housing's status as the family's main home, not just residency.
• IMI and AIMIpaid equally by all owners, regardless of residency.

For those planning to relocate and get status, tax residency is not just obligations, but also access to a number of benefits. It's worth calculating the scenario with a consultant in advance, especially if there's income and assets in several countries.

Summary table: tax - when it's paid - the rate

Let's put all of Portugal's 2026 real estate taxes into one table - a convenient checklist for budgeting both at entry and over the ownership and exit horizon.

This is a benchmark, not a final calculation: thresholds are indexed by the budget, the IMI rate is set by the municipality, and the final figure for a specific deal depends on the buyer's status, the property type, and its VPT.
