Investing in Luxembourg: Brokers, ETFs and Taxes 2026

Last updated: 3 September 2026

Table of Contents

Luxembourg is one of the world’s principal cross-border investment-fund centres and, together with Ireland, a leading domicile for European UCITS funds. Residents have access to international brokers, Luxembourg banks, global exchanges and a large selection of ETFs and investment funds.

For private investors, the most notable tax feature is Luxembourg’s treatment of capital gains. A gain on an ordinary portfolio holding of less than 10% is generally exempt when the security has been held for more than six months. Short-term gains and gains on a substantial participation can remain taxable.

This does not make every investment gain tax-free. The six-month holding period, the more-than-10% substantial-participation test, the €500 annual short-term-gain threshold and the rules for dividends and interest must be considered separately.

This guide is intended primarily for individuals who are tax resident in Luxembourg and manage a private portfolio outside a business activity. Residence, account ownership, asset type and the size of a participation can change the result.

The Investment Landscape in Luxembourg

Luxembourg residents can generally invest in:

Luxembourg and international listed shares;
UCITS ETFs and mutual funds;
government and corporate bonds;
money-market funds and instruments;
structured products;
managed portfolios and private-banking products;
pension and insurance-based investments; and
derivatives, CFDs and forex products where lawfully offered.

The Commission de Surveillance du Secteur Financier supervises banks, investment firms, fund managers and other regulated financial-sector participants within its remit. Luxembourg and cross-border EEA firms operate within MiFID II, PRIIPs, UCITS and related EU frameworks.

Luxembourg’s role as a fund domicile does not mean that residents receive special tax treatment merely because an ETF is domiciled locally. Investor taxation depends on the resident’s circumstances and the nature and timing of the income or disposal.

Before selling an investment, estimate the possible outcome with the Finorum Capital Gains Tax Calculator for Luxembourg, then check it against the official rules and the taxpayer’s complete annual position.

Trading.com is not included in this table. It is a forex and CFD provider for the purposes of this guide and appears only in the dedicated CFD section.

Interactive Brokers

Interactive Brokers Ireland generally accepts eligible Luxembourg residents and offers shares, ETFs, bonds, options and other instruments across many markets. Investors remain responsible for determining the Luxembourg tax treatment and retaining dates and acquisition costs for the six-month test.

Trading 212

Trading 212 offers an Invest account with shares, ETFs and fractional investing and a separate CFD service. Statements can support record keeping but do not replace a Luxembourg tax assessment or return.

XTB

XTB offers cash securities and CFDs, depending on the instrument, entity and country. Investors should verify on the order ticket whether they acquire an underlying security or leveraged exposure.

eToro

eToro offers shares, ETFs and CFDs. Ownership can depend on the instrument, leverage, position direction and serving entity. A ticker or asset name alone does not prove direct ownership.

Saxo

Saxo provides broad multi-asset access. Luxembourg residents should compare commissions, FX and custody fees and confirm the legal entity and compensation scheme covering their account.

Swissquote Bank Europe

Swissquote Bank Europe is a Luxembourg bank supervised by the CSSF and offers access to international securities markets. Investors should compare its account, custody and trading charges and distinguish deposit protection from protection of investment assets.

Freedom24

Freedom24 provides access to shares, ETFs and bonds through its European investment firm. Investors should confirm the legal entity, current fees and the applicable home-state investor-compensation arrangements.

LYNX

LYNX provides access to international markets through Interactive Brokers infrastructure in supported jurisdictions. The contractual entity, custody chain and current Luxembourg onboarding should be checked directly.

DEGIRO

DEGIRO should not be described as definitely accepting new Luxembourg-resident accounts without a successful current onboarding check. Availability in neighbouring EU countries does not establish availability in Luxembourg.

Domestic Investment Platforms

Spuerkeess

Spuerkeess provides self-directed and advised investment services through its banking channels. Its local integration may suit residents who prefer Luxembourg statements and support, but full trading and custody costs should be compared.

BGL BNP Paribas

BGL BNP Paribas offers securities and investment products through its Luxembourg banking service. Available exchanges, minimum commissions, advice and custody charges depend on the selected service.

Banque Internationale à Luxembourg

BIL provides self-directed and managed investment services. Investors should establish whether a product is an execution-only security, fund, mandate or structured product before comparing costs and risks.

Fideuram Direct Luxembourg

Fideuram Direct provides a Luxembourg digital investment offering. Because product scope and eligibility can evolve after launch, investors should confirm current retail onboarding, the CSSF-authorised entity and available securities.

Trade Republic

Trade Republic generally supports eligible Luxembourg tax residents and offers shares, ETFs, bonds and savings plans. It should be treated as a foreign/EEA digital broker rather than assumed to complete Luxembourg tax filing for the client.

Traditional Bank Brokers

Luxembourg’s banks often combine brokerage, custody, advice and wealth management. They may be convenient for local reporting and multi-currency banking but more expensive than execution-only brokers.

Bank	Typical investment service	Potential strength	Point to compare
Spuerkeess	Self-directed and advised investing	Strong local network and integrated banking	Custody and foreign-exchange charges
BGL BNP Paribas	Brokerage, funds and advice	International group infrastructure	Service tier and product costs
BIL	Brokerage, funds and portfolio management	Luxembourg private and retail banking	Execution-only availability and minimum fees
Banque de Luxembourg	Advisory and discretionary investment services	Wealth-management expertise	Eligibility and all-in management cost
Banque Raiffeisen	Securities and fund services	Cooperative local banking relationship	Platform range and tariff
ING Luxembourg	Investment and banking products	Integrated banking for eligible clients	Current product availability and fees

A bank deposit is not the same as a security. Deposit-guarantee protection applies to eligible cash deposits, not losses caused by a fall in an ETF, share or bond price.

CFD and Forex Brokers

CFDs are leveraged derivatives and do not provide ownership of the referenced share, ETF, currency or commodity. Providers that offer both cash investments and derivatives appear again here because the products are legally and economically different.

Provider	General availability in Luxembourg	Main point to verify
XTB	Generally available	CFD account versus underlying securities
eToro	Generally available	CFD status on the trade ticket
IG	Generally available	Primarily leveraged products
CMC Markets	Generally available	CFD-focused service
Plus500	Generally available	CFD-focused service
Pepperstone	Generally available	Forex and CFD focus
AvaTrade	Generally available	Forex and CFD focus
Admirals	Generally available	Products depend on serving entity
FP Markets	Verify current onboarding	Entity and EEA cross-border permission
Trading.com	Verify current Luxembourg onboarding	Forex and CFD service, not ordinary ETF ownership

EU retail CFD measures include leverage limits, margin close-out, negative-balance protection and standardised risk warnings. These controls do not remove the risk of rapid loss. Check the provider in the CSSF supervised-entities search and its home regulator’s register.

ETF Investing from Luxembourg

Luxembourg residents can generally buy a broad range of UCITS ETFs, including Luxembourg- and Ireland-domiciled products covering:

global, regional and country equity markets;
developed and emerging markets;
government and corporate bonds;
money markets;
sectors, factors, themes and dividend strategies;
commodities through appropriate exchange-traded structures; and
accumulating and distributing share classes.

UCITS is a regulatory framework, not a guarantee of capital or performance. Investors should read the KID and prospectus and check the fund’s domicile, replication method, securities lending, total cost, currency exposure, size and index methodology.

Can Luxembourg Residents Buy US-Domiciled ETFs?

Most Luxembourg retail clients cannot newly purchase US-domiciled ETFs through an EEA-regulated broker because the manufacturer generally does not provide the PRIIPs Key Information Document required for retail distribution.

This is an EEA distribution restriction, not a Luxembourg-specific prohibition on ownership. Professional-client treatment and limited special situations may differ. Existing holdings can often be retained or sold even where further purchases are unavailable.

UCITS alternatives can have similar index exposure but are not identical. Domicile, withholding within the fund, replication, fees, trading currency and distribution policy can differ.

US-domiciled example	UCITS example with broadly comparable exposure	UCITS ISIN
SPY	iShares Core S&P 500 UCITS ETF	IE00B5BMR087
VOO	Vanguard S&P 500 UCITS ETF	IE00BFMXXD54
QQQ	Invesco EQQQ NASDAQ-100 UCITS ETF	IE0032077012
VT	Vanguard FTSE All-World UCITS ETF	IE00BK5BQT80

These are illustrations, not recommendations or exact substitutes.

Examples of Broad UCITS ETFs

ETF	ISIN	Reference exposure
iShares Core MSCI World UCITS ETF	IE00B4L5Y983	MSCI World
Vanguard FTSE All-World UCITS ETF, distributing	IE00B3RBWM25	FTSE All-World

iShares Core S&P 500 UCITS ETF	IE00B5BMR087	S&P 500
Xtrackers MSCI Emerging Markets UCITS ETF	IE00BTJRMP35	MSCI Emerging Markets

Confirm the ISIN and share class before ordering. Tickers can differ by exchange and currency.

Tax Treatment of ETFs

Luxembourg does not impose a German-style annual deemed-income charge on an ordinary private investor merely because an accumulating ETF increases in value. Tax analysis generally arises from a distribution or disposal.

Accumulating ETFs

An accumulating ETF reinvests income within the fund rather than paying cash to the investor. For an ordinary private holding below the substantial-participation threshold, a disposal gain after more than six months is generally exempt. A sale within six months can produce a taxable speculative gain.

Accumulation does not guarantee exemption: a deemed distribution, liquidation, fund reorganisation or other event may require separate analysis.

Distributing ETFs

Cash distributions are generally investment income and can be taxable at Luxembourg progressive rates. The 50% exemption applicable to qualifying dividends from eligible fully taxable companies should not automatically be applied to every ETF distribution. The fund’s legal form, payment classification and eligibility must be established.

Records Needed

Investors should retain:

acquisition and disposal dates;
purchase cost and transaction fees;
sale proceeds;
the ISIN and legal form of the fund;
distribution statements;
foreign withholding-tax certificates; and
evidence relevant to tax residence and participation size.

Opening an Investment Account

1. Select the Broker Type

Compare an international execution-only broker, a Luxembourg online bank and a traditional bank service. Tax administration is not automatically completed merely because the intermediary is located in Luxembourg.

2. Compare the Full Cost

Examine commissions, minimum dealing fees, custody, FX spreads, market-data subscriptions, fund entry charges, advisory fees and transfer-out costs. Luxembourg bank tariffs can differ significantly by service tier.

3. Prepare Documents

Most providers request:

passport or national identity card;
proof of address;
Luxembourg national identification or tax data;
tax-residence self-certification;
a bank account in the client’s name; and
information about investment knowledge, objectives and source of wealth or funds.

4. Verify the Legal Entity

Confirm the provider in the CSSF or relevant home-state register, identify the contracting entity and read its custody and compensation disclosures. Cross-border passporting does not move the account into Luxembourg’s compensation scheme.

5. Preserve Lot-Level Records

The six-month rule makes dates essential. Do not rely only on an annual performance figure. Retain transaction confirmations and establish which acquisition lot was disposed of where multiple purchases of the same security exist.

Taxes for Investors in Luxembourg

Ordinary Portfolio Capital Gains

For a private investor whose participation is below 10%:

a gain on a security held for more than six months is generally exempt; and
a gain realised after six months or less is generally a speculative gain taxed at ordinary progressive income-tax rates.

The official Guichet.lu capital-gains guidance contains the operative table and should be checked together with the current income tax rules.

Use the Luxembourg Capital Gains Tax Calculator for an estimate, but verify the holding period, participation and annual net result.

The €500 Short-Term-Gain Threshold

If total net speculative gains for the calendar year are less than €500, they are not taxable. If the amount exceeds €500, the threshold is not a deduction: the taxable result is not simply reduced by €500.

The €500 figure concerns relevant annual speculative gains. It is not a general annual capital-gains allowance for every kind of investment disposal.

Substantial Participations

A participation is substantial where the taxpayer, alone or together with a spouse or partner and minor children, directly or indirectly held more than 10% of the company’s capital at any time during the five years preceding the disposal.

For such a participation:

a gain within six months is taxed at ordinary progressive rates; and
a gain after more than six months remains taxable, generally at half the taxpayer’s overall rate, with a €50,000 allowance that is normally available over a ten-year period and doubled for jointly taxed spouses or partners.

These substantial-participation rules are mainly relevant to founders, owner-managers and large shareholders, not ordinary diversified ETF investors.

Capital Losses

Capital losses may offset gains within the applicable miscellaneous-income category and classification. Official guidance states that securities capital losses cannot be offset against unrelated income categories and are not carried forward to later tax years. This is important for investors accustomed to multi-year loss carryforwards elsewhere.

Dividends

Luxembourg-source dividends are generally subject to 15% withholding tax, which is credited in the resident’s final assessment rather than necessarily representing the final liability.

Qualifying dividends from a fully taxable Luxembourg company, an eligible EU company or a qualifying treaty-country company can benefit from a 50% exemption at the individual level. Since 2025 taxpayers can, in specified circumstances, waive this exemption; professional advice may be appropriate before doing so.

The 50% exemption should not be assumed for every fund or ETF distribution. Foreign withholding and treaty relief depend on the source state and evidence.

€1,500 Investment-Income Allowance

The first €1,500 of net income from movable capital is exempt for an individual taxpayer. It is doubled to €3,000 for spouses or partners assessed jointly. This allowance is separate from both the €500 speculative-gain threshold and the 50% qualifying-dividend exemption.

The Luxembourg Inland Revenue explanation also identifies a minimum €25 deduction for expenses connected with movable investment income, doubled for joint assessment.

Interest

Interest paid by a Luxembourg paying agent to a resident individual can be subject to the 20% final withholding regime known as RELIBI, subject to its statutory scope. Foreign interest and interest outside that regime may instead require declaration and progressive taxation. The €1,500 movable-income allowance and special interest exemptions must be considered under their own conditions.

Foreign Investments and Worldwide Income

Luxembourg tax residents are generally taxable on worldwide income, including reportable foreign dividends, interest and taxable capital gains. Foreign withholding may be creditable or exempt under domestic law and a tax treaty, but relief is limited by the applicable rules and requires documentation.

A foreign broker normally does not complete the Luxembourg return. A Luxembourg broker can withhold particular payments but still does not eliminate the investor’s duty to assess other income.

For broader context, see the Finorum Luxembourg Tax Guide.

Filing Deadline

Individuals required to file generally use Form 100. The Administration des contributions directes confirms that a return for tax year N is due no later than 31 December of year N+1 and that this statutory deadline cannot be extended beyond 31 December.

Accordingly, the standard deadline for the 2025 tax return is 31 December 2026. This should not be confused with the filing deadline for 2026 income, which falls in 2027.

Regulation and Investor Protection

CSSF Supervision

The CSSF supervises relevant Luxembourg banks, investment firms, fund managers and markets. An EEA broker serving Luxembourg cross-border may remain primarily supervised by its home authority.

Always check the exact legal entity. Registration does not guarantee investment performance and does not protect against a cloned website.

Investor Compensation — SIIL

The Système d’Indemnisation des Investisseurs Luxembourg covers eligible clients of participating banks and investment firms where the institution cannot return covered money or financial instruments.

Coverage is limited to €20,000 per eligible person per institution. It does not reimburse market-value losses. Properly segregated client securities should ordinarily be returned; SIIL addresses a qualifying shortfall such as missing assets.

A cross-border broker may be covered by its home country’s investor scheme rather than SIIL.

Deposit Protection — FGDL

The Fonds de garantie des dépôts Luxembourg covers eligible deposits up to €100,000 per person per bank. Deposit protection and SIIL cannot both compensate the same claim.

Securities, ETFs and investment-market losses are not bank deposits. Uninvested broker cash may be held as a bank deposit, safeguarded client money or another product, so the account terms matter.

Client-Asset Segregation

Segregation, SIIL and FGDL are distinct safeguards. Segregation is intended to separate client instruments from the firm’s assets; SIIL can respond to a covered failure to return assets; FGDL protects eligible bank deposits. None protects against price movements or issuer default within a security.

Is Luxembourg a Good Base for Investors?

Potential Advantages

generally exempt long-term gains for ordinary portfolio holdings below 10%;
a large and sophisticated financial-services sector;
extensive access to UCITS ETFs and global markets;
domestic, international and bank-broker choices;
a 50% exemption for qualifying dividends;
a €1,500 movable-investment-income allowance; and
established EU and Luxembourg protection frameworks.

Potential Disadvantages

short-term gains can be taxed at high progressive rates;
substantial holdings remain subject to special rules after six months;
brokers generally do not prepare the complete Luxembourg return;
foreign dividends and interest can require treaty and credit analysis;
most US-domiciled ETFs are unavailable for new EEA retail purchases; and
traditional bank brokerage and custody can be expensive.

Luxembourg can be attractive for genuine long-term private investors with diversified holdings below 10%. It is less straightforward for frequent traders, founders disposing of large company stakes or investors with complex foreign income.

Compare Luxembourg and Plan the Wider Move

Investment tax should be compared with earnings, housing and living expenses. Relevant Finorum resources include:

Conclusion

Luxembourg combines unusually broad investment access with favourable treatment for genuine long-term private holdings. A non-substantial portfolio gain is generally exempt after more than six months, while a short-term gain can be taxable at progressive rates once the annual net amount reaches the €500 threshold.

Investors must keep the separate rules distinct: substantial participations use a more-than-10% test over the preceding five years; qualifying dividends may receive a 50% exemption; and the €1,500 movable-income allowance is unrelated to the €500 speculative-gain rule. Accurate dates, participation records and foreign-tax documents are therefore essential.
