Capital gains tax in Portugal in 2026: real estate, stocks, crypto

What capital gains are and why they're taxed

Capital gains, mais-valias in Portuguese, is the positive difference between an asset's sale price and its purchase cost. If you bought an apartment for €200,000 and sold it for €300,000, the gain is €100,000. It's this figure (after lawful deductions), not the whole deal amount, that's the object of tax. The logic is simple: the state taxes not your money in general, but the profit earned on the asset.

In Portugal, capital gains are a category of income within the individual income tax system (IRS, Imposto sobre o Rendimento das Pessoas Singulares). It's designated Category G and covers selling real estate, stocks and other securities, company shares, and, more recently, crypto assets. Separate rules apply to each type of property, which is exactly why you can't speak of a single "capital gains tax rate in Portugal" - there are several.

Three factors determine how much you pay: the asset type (an apartment, stocks, or crypto), the holding period (especially for cryptocurrency), and your tax status. We break down in detail who counts as a Portugal tax resident and who doesn't in our article onPortugal tax residency- half the calculation depends on this status.

Resident or non-resident: why it changes everything

Before calculating the tax, you need to determine your status. A person becomes a Portugal tax resident if they spend more than 183 days in the country within 12 months, or have a permanent home here considered their usual place of residence. A resident declares and is taxed in Portugal on worldwide income, a non-resident only on income from Portuguese sources.

For capital gains, the difference is fundamental:

• Residentfor real estate includes only 50% of the profit in the taxable base, and then this half is added to other income and taxed on the progressive IRS scale.
• Non-residentby default pays, roughly, a flat 28% on the whole real estate gain. That said, EU and EEA residents are entitled to choose the same regime as Portuguese residents - including only 50% of the profit and applying the progressive scale.

This fork means the same house, sold with identical profit, produces a different tax burden depending on where you live and which status you chose. So planning a sale always starts with a answer to the question: who are you for the Portuguese tax authority in the deal year. All specific rates and thresholds here and below are given approximately - before the deal they need checking for the current tax year, since IRS parameters are revised annually.

Real estate for a resident: the 50% rule and the progressive scale

This is the most common case for those living in Portugal. When a resident sells real estate, only half the capital gain enters the tax base. The other half isn't taxed at all - this is a base relief built into the IRS system.

The calculation mechanics look like this:

• We calculate the gain: the sale price minus the adjusted purchase cost and allowable expenses.
• We take 50% of this figure.
• We add this 50% to the year's other income (salary, rent, pension, and so on).
• We apply the progressive IRS scale - roughly from low rates up to 48% at the top brackets, plus a possible solidarity surcharge on very high incomes.

The practical meaning: if your total income is small, the effective rate on the gain can turn out fairly mild. If you're already at the top of the scale, half the gain will fall under a high percentage. This is exactly why it sometimes makes sense to plan large deals across years. We've collected the country's general property tax logic in our guide toreal estate taxes in Portugal.

Real estate for a non-resident: flat rate and the EU option

For non-residents, a simple but strict logic historically applied: the entire gain from selling Portuguese real estate was taxed at a flat rate, roughly 28%, with no 50% relief. That is, a non-resident paid tax on the entire profit.

However, under pressure from European law, the situation changed. Residents of other EU and European Economic Area countries gained the right to choose the same regime as Portuguese residents:

• including only 50% of the gain in the base;
• taxing it on the progressive IRS scale rather than the flat rate.

In practice this means an EU/EEA taxpayer needs to compare the two scenarios and choose the advantageous one. With a small profit and modest other income, the resident regime (50% base + scale) often turns out cheaper than the flat 28%. With very high profit, the picture can be the opposite. For non-residents from outside the EU/EEA, including many CIS countries, the flat approach applies by default - and it's important to factor this into the calculation before the deal. Exact rates and the option's availability need confirming for the current year, since the non-resident rules have been adjusted.

Relief when reinvesting in a primary home

The most powerful real estate relief concerns selling your primary, permanent home. If you sell a house or apartment that was your main place of residence and reinvest the proceeds into buying, building, or improving another primary home, the capital gain may be fully or partially exempt from tax.

Key conditions for the relief (approximate, need checking for the deal year):

• The property sold is specifically the primary home, not investment or rental real estate.
• The new home also becomes your primary residence- for you and your family.
• Reinvestment within the set deadlines- generally in a window from a few months before the sale to 36 months after it.
• The property is in Portugal, the EU, or the EEA- the reinvestment geography has been expanded to the whole zone, not just Portugal itself.
• Partial reinvestment - partial relief:if you didn't invest all the proceeds, a proportional part of the gain is exempt.

An important detail: the relief is calculated from net proceeds (minus any mortgage loan paid off at sale), not from the full price. So with a mortgage, calculating the amount that needs to be reinvested is done carefully. This is the very relief that lets families change homes within Portugal or Europe without losing half the profit to tax.

Stocks and securities: a flat 28%

Gains from selling stocks, bonds, fund units, and most other financial instruments in Portugal are taxed at a flat rate, roughly 28%. This applies to both Portuguese and foreign securities, if you're a Portugal tax resident declaring worldwide income.

What's important to understand about this block:

• The base is the net financial result for the year.Profits and losses on securities deals within the year are netted: losses reduce the taxable gain.
• A flat 28% - the default rate.But the taxpayer can choose to include this income in the overall progressive IRS scale if it's more advantageous for them (englobamento).
• A special case - assets from "tax havens".A higher rate may apply to instruments tied to blacklisted jurisdictions.
• Holding periodfor stocks, unlike cryptocurrency, doesn't directly affect the rate itself, though separate adjustments exist for some long-term positions.

For non-residents, gains on securities are also taxed, roughly, at a rate around 28%, but here it's critical to look at the double taxation treaty between Portugal and your country of residence - it may reassign the right to tax. Before a large portfolio sale, this question is always worked through separately.

Cryptocurrency: the holding year decides everything

Until recently Portugal was known as a "crypto haven": gains from individuals selling cryptocurrency weren't taxed. The rules have now changed, but remain relatively mild and tied to the holding period.

The main 2026 logic (approximate):

• Held less than 365 days- the gain is taxed at a flat rate of around 28% (with the option to include it on the progressive scale).
• Held 365 days or longer- the gain from the sale is exempt from tax. This is a surviving "long-term" incentive for long-term holders.

There are important caveats. The term-based exemption concerns gains from selling cryptocurrency for fiat money. Exchanging one cryptocurrency for another, income from staking, mining, or activity that's essentially professional in nature may be classified differently - as business income or capital income - and taxed under its own rules. In addition, an asset tied to a blacklisted jurisdiction may lose the right to relief.

Cryptocurrency is the fastest-changing part of the Portuguese tax landscape, so a specific case is best checked against current rules. A detailed breakdown is in our separate article oncryptocurrency tax in Portugal.

Summary table: asset - resident - non-resident

Let's gather everything into one table so the differences by asset type and status are visible. Rates and thresholds are given approximately and need checking for the specific tax year - IRS parameters are updated annually, and the rules for non-residents and crypto have changed more often than the rest in recent years.

This table is a starting point, not the final calculation. The outcome is affected by your other income for the year, any losses, housing status, and the provisions of international treaties. So before the deal it's worth calculating both scenarios in figures.

The return and payment deadlines

Capital gains are declared in the annual IRS return, filed the year after the deal. Real estate and financial assets are reported in the relevant return annexes (Annex G for real estate, separate sections for securities and crypto).

What matters about the procedure:

• The deal doesn't mean immediate payment.The tax is calculated and paid at year-end through the IRS return, not at the moment the sale deed is signed.
• A non-resident also needs to declarePortuguese gain - having a flat rate doesn't remove the obligation to file a return.
• Filing deadlinesfall, roughly, in the spring-summer of the year following the deal year; the tax authority publishes exact dates.
• Keep your documents in advance.By the time you file, you must have all expense confirmations in hand, or the deductions won't go through.

A separate practical point for non-residents: when selling real estate, a Portuguese tax number (NIF) and, in some cases, a tax representative may be required. These formalities are best sorted before the deal, so as not to slow down either the sale or the subsequent return. We keep the general income tax picture in our article onincome tax in Portugal.

Non-residents from the CIS: treaties and compliance

For sellers from Russia and other CIS countries, two layers are added to the standard logic: international tax treaties and enhanced source-of-funds compliance.

What to pay attention to:

• Double taxation treaties.For real estate, the right to tax the gain almost always stays with the country where the property is located - that is, Portugal. But for stocks and other financial assets, the treaty may assign the tax to the seller's country of residence. The status of the treaties themselves has changed in recent years, so it needs to be checked at the time of the deal.
• Double taxation.If the tax is paid in Portugal, your country of residence usually gives a credit - but the mechanism depends on the applicable treaty and its status.
• Source of funds and sanctions compliance.Portuguese banks and notaries carefully check the origin of funds. Everything must go strictly within the law, with no circumventing restrictions, and a transparent documentary chain for every transfer.

The practical takeaway: for CIS residents, the deal's tax side is inseparable from the funds' legal cleanliness. These matters are worked through together and in advance, not after the bank has blocked the incoming proceeds.

Common mistakes when calculating capital gains

Watching sales in Portugal, we see recurring mistakes that either lead to overpaying tax or to a dispute with the tax authority. Let's break down the main ones.

• Didn't keep documents.Without receipts for renovations, contracts, and expense receipts, deductions can't be proven - the base is calculated at maximum, and the tax comes out inflated.
• Forgot about the inflation coefficient.With holding longer than two years, indexing the purchase cost noticeably reduces the gain, but it needs to be applied in the return.
• Mixed up your status.EU/EEA non-residents who don't use the resident-regime option overpay under the flat rate where the scale would have been cheaper.
• Miscalculated the reinvestment.The primary home relief is calculated from net proceeds minus any mortgage paid off, and partial investment gives only partial exemption.
• Sold crypto a few days short of a year.The difference between 364 and 365 days of holding is the difference between a ~28% rate and zero. The term needs to be tracked.

Each of these mistakes costs real money. Most of them are easy to prevent by calculating the deal before signing, not after.

An expert's view: how to legally reduce the tax

Reducing capital gains tax in Portugal isn't about "schemes", but the competent use of what the law directly provides for: the 50% rule for residents, primary home relief, inflation indexing, netting losses on securities, and the one-year cryptocurrency period. The main resource for savings isn't laid down at the moment of sale, but long before it - in how you arranged the purchase, kept documents, and planned your tax status for the deal year.

We'll calculate your capital gains tax in advance

Capital gains tax in Portugal isn't one rate, but a fork of a dozen scenarios: asset type, your status, holding period, home relief, an international treaty. A mistake on any of these points turns into an overpayment or, conversely, a tax authority claim. This is especially critical for CIS residents, where all the attention is on the source of funds and compliance - here it's important to conduct the deal strictly within the law and with a clean documentary history.

How the base is calculated: deducting costs and inflation

The most common mistake is calculating the gain as a simple difference between the purchase and sale price. In reality the base is significantly smaller, because the law allows a whole range of deductions, especially for real estate.

What reduces the taxable gain:

• The purchase cost adjusted for inflation.If more than two years passed between the purchase and the sale, the purchase price is multiplied by the official currency devaluation coefficient - meaning it's indexed for inflation. The longer you owned it, the more the counted purchase cost "grows", and the smaller the taxable profit.
• Improvement costs.Documented costs for repairs, reconstruction, and improvements to the property over the last years of ownership are added to the purchase cost.
• Purchase and sale costs.The property transfer tax (IMT), stamp duty, notary, registration, agency commission, energy certificate - all of this is deductible.

For securities the base is calculated more simply - as the difference between the sale and purchase price, factoring in fees, with no inflation coefficient. But in any case, the key to reducing the tax is keeping all documents and receipts from the moment of purchase. Without them a deduction can't be proven, and the tax authority will calculate the base at maximum.

Bottom line: what matters before selling

Capital gains tax in Portugal can't be reduced to a single figure - it all depends on the combination of "asset + status + holding period". For a resident's real estate, half the profit enters the base; a non-resident by default pays roughly 28%, but EU/EEA citizens can choose a milder regime. Stocks and crypto under a year fall under a flat rate of around 28%, and cryptocurrency held longer than a year is exempt. The reinvestment relief for a primary home can zero out real estate tax entirely.

Before any large sale, three things are worth doing: determining your tax status for the deal year, gathering all expense documents for deductions, and calculating both taxation scenarios in figures. For CIS residents, working through international treaties and the cleanliness of the funds' source is added to this.
