Claiming the exclusion requires ticking that the securities are admitted to trading on a regulated market, or are units in an open-ended OIC. That field exists on Anexo G. It does not exist on Anexo J — the annex every foreign-source disposal uses. Reported in January 2026 by EasyTax in Jornal Económico, which states plainly that on Anexo J there is currently no field for indicating whether the securities qualify.

There is a route out in theory: where the registering or depositary entity is established in Portugal and files declaração Modelo 33, disposals can appear pre-filled on Anexo G. But XTB — the broker with the CMVM-registered branch — allocates the annexes on its own tax guide by the residence of the issuer, not the broker: Anexo G for assets issued by resident entities, Anexo J boxes 9.2A and 9.2B for assets issued by non-resident entities. An Irish-domiciled UCITS ETF is a non-resident issuer.

Portugal applies no annual tax on unrealised gains, unlike Germany or the Netherlands. Accumulating share classes reinvest internally and defer everything until you sell — which also means the holding clock keeps running rather than resetting on a distribution. Irish-domiciled UCITS ETFs suffer 15% US withholding at fund level rather than 30%, so the wrapper costs you little.

If you sell securities held under 365 days and your total taxable income including those gains reaches the top bracket — €83,696 for 2025 income, indexed annually — aggregation at progressive IRS rates becomes mandatory rather than optional. Below that threshold, englobamento is a choice, and it generally only helps if your effective rate is under 28%. It is elected in box 15 of Anexo G or box 9.2 C of Anexo J.

XTB and Trade Republic hold local registrations — CMVM number 341 and a Banco de Portugal branch registration respectively. The others passport in: Trading 212 through Cyprus, Lightyear from Estonia, Interactive Brokers from Ireland. The compensation scheme follows the home state, not Portugal, so the figures differ: XTB publishes €20,100 under the Polish scheme, Lightyear €20,000 under the Estonian fund, IBKR 90% of losses to €20,000 in Ireland, Trading 212 €20,000 through the Cypriot ICF.

• 35% withholding on Portuguese-issuer dividends. XTB holds shares in an omnibus account, so the Portuguese paying entity cannot identify beneficial owners and applies the highest rate rather than the 28% liberatory rate. XTB states this on its own tax guide. It matters if you hold Portuguese equities; it does not affect Irish-domiciled ETFs.
• The same mechanism produces 30% on US-listed shares, though XTB allows W-8BEN to be filed on the platform, which brings that to 15%.
• 0.5% currency conversion — the highest of the five. Irrelevant if you buy EUR-listed UCITS ETFs, expensive if you buy USD-listed shares regularly.
• Investor compensation is the Polish scheme at €20,100, published on XTB’s own Portuguese terms page — not a Portuguese scheme.
• XTB does not publish a withholding rate on interest. Its interest page says tax may be withheld and remitted by XTB S.A. or its foreign branches at the rates in force. Do not assume 28%; check your monthly statement, which shows the amount deducted.
• CFDs sit alongside the real-share account. Use the stocks and ETFs side only.

• The FX margin on asset purchases is not published. Trade Republic quotes margins as absolute amounts in the quoted currency on foreign-currency income — USD 0.0014, GBP 0.0011, CHF 0.0014. Whether a margin applies when you buy a non-EUR asset is not stated in its price list at all. On a page about eight-year holding costs, an unquantifiable recurring cost is a real mark against it.
• Local tax reporting is contractually optional. The customer agreement says Trade Republic may provide local tax reporting, without obligation or liability, and reserves the right to discontinue it at the end of a tax year on four weeks’ notice.
• Savings plans run from €10 to €10,000 per execution — not from €1, whatever the marketing says.
• Savings plan orders settle at a single average price pooled across all customers buying that instrument that day, not at a price you see at a moment in time.
• Cash above the Partner Amount sits in a money market fund rather than a deposit. Trade Republic sets that threshold and does not publish it.
• Moving country is expressly grounds for termination without notice — including moving to another country Trade Republic serves.

• Fractional positions cannot be transferred to another broker. On an eight-year horizon this is a real constraint: you either sell them or top up to whole shares before moving. Selling restarts the holding clock.
• Uninvested EUR cash earns no interest. Lightyear pays cash interest only to UK residents on GBP and Hungarian residents on HUF. The rates quoted elsewhere belong to Savings, a J.P. Morgan Asset Management money market fund for Portuguese residents — an investment product where capital is at risk, not a deposit.
• Auto-invest runs only on fractional instruments. Anything non-fractional added to a Plan has to be bought separately, and money market funds cannot go into Plans at all.
• Lightyear does not publish a UCITS ETF count — the figure quoted publicly spans stocks, funds and bonds together.
• Lightyear Europe AS is authorised by the Estonian Financial Supervision Authority and passported into Portugal. Compensation is the Estonian Investor Protection Sectoral Fund up to €20,000; crypto assets are excluded.
• No Portuguese-language platform or local office. Support is email and in-app chat only, with no telephone dealing.
• Card, Apple Pay and Google Pay deposits cost 0.6%. SEPA transfers are free.

• 0.15% FX with no minimum — the cheapest published conversion of the five, and it never exceeds 0.15% including weekends.
• €0 commission on shares, fractional shares and ETFs. For EU clients the Invest universe is shares, fractional shares and ETFs only — bonds are a UK-account product, not an EU one.
• Portuguese clients contract with Trading 212 Markets Ltd, the Cypriot entity, CySEC licence 398/21 — not the German entity that serves the Netherlands, Germany, France and Spain. Compensation is the Cypriot ICF up to €20,000.
• On the Cypriot entity, Interactive Brokers is the sole custodian. There is no BNY Mellon leg as there is on the UK and German entities.
• Holdings sit in a mixed omnibus custody account. On an unreconciled shortfall following a custodian default, clients share in that shortfall pro rata.
• Pies and AutoInvest automate recurring contributions, though the operating limits behind them are published only in help articles, not in the terms.

Best for: investors who buy USD- or GBP-listed assets regularly and want the conversion cost as low as it goes.

• Portugal is priced above most of Europe. Tiered carries a €1.25 minimum, but Fixed is 0.15% with a €6.00 minimum — against 0.05% and €3.00 for Austria, Belgium, France, Germany, Italy, the Netherlands and Spain. Portugal is one of only three expensive outliers in IBKR’s European table.
• Fractional shares are not offered in Portugal. They are available in eleven European markets; Portugal is not among them. That rules out small automated contributions in fractions.
• Two separate FX mechanisms, and the difference is the whole story: auto-conversion at 3 basis points of trade value, or a manual spot FX order from 0.20 basis points with a $2.00 minimum per order.
• That floor is what governs at retail size. $2 on a €500 conversion is 0.4%; on €10,000 it is 0.02%. The break-even against Trading 212’s 0.15% sits near €1,300 per conversion. Below it, Trading 212 wins. Above it, IBKR wins and keeps winning.
• No custody fee, no inactivity fee, no minimum account balance.
• EU clients are served by Interactive Brokers Ireland Ltd; Irish compensation covers 90% of losses up to €20,000.

Best for: larger portfolios converting meaningful sums at a time, or investors who need markets the others do not carry.

eToro does publish Portugal-specific real-stock commissions — $1 on most exchanges and $2 on Australia, Hong Kong, Dubai, Abu Dhabi and Tokyo, in force since 11 August 2024 — and Portuguese clients get a local EUR-denominated account. The problem is structural rather than a missing figure: the underlying account is denominated in USD and conversion between your local currency and USD runs at 0.75%. On a monthly contribution held for years, that sits in front of every euro before it buys anything. It is a reasonable place to trade and a poor place to accumulate. Full eToro review.

Saxo is a strong platform with deep ETF coverage, but it publishes no Portuguese fee schedule and has no Portuguese entity. Every Saxo number circulating on Portuguese comparison pages is imported from another country’s price list. Rather than quote a Dutch or French figure and label it Portuguese, we quote nothing. Saxo review.

Scalable serves several EU markets cross-border under freedom of services, with the host authorities in France, Italy, the Netherlands, Spain and Austria notified. Portugal is not on that list in its own documentation, and no source places it there. Separately, a currency markup exists in its binding contract but its size is published nowhere — so any claim that Scalable charges no FX fee is refuted regardless of country. Scalable review.

Mintos accepts Portuguese clients and Portuguese-issued card deposits, but two facts disqualify it here. Positions cannot leave the platform — there is no transfer out to another broker. And country-specific tax reports exist for Estonia, Germany and Latvia only; Portugal gets a generic template. On a page about holding for eight years and documenting a cost basis, those are structural, not footnotes. Mintos review.

• Hold EUR, USD and GBP and want them side by side rather than converted back each time.
• Want the stamp-duty interaction handled and documented rather than left to you.
• Care that your shares are never lent out.
• Can live with buying whole shares if you might transfer out later.

• Trading 212: convert under roughly €1,300 at a time and want the lowest published rate at 0.15%.
• IBKR: convert well above that, where the $2 spot floor stops mattering and 0.20 bps takes over.
• Accept that neither offers any Portuguese tax handling, and that IBKR has no fractional shares in Portugal.
