Its appeal lies not only in its AAA-rated economy and high standard of living, but also in its pragmatic tax framework, multilingual culture, and investor-friendly institutions.

For expats, understanding how Luxembourg integrates residency, taxation, and investment incentives is essential.

Why Invest in Luxembourg

For one big reason, Luxembourg’s investor residence program provides several routes for non-EU nationals to gain long-term residence while contributing to the local economy. The law offers three main options:

• Business investment: A minimum of €500,000 invested in an existing Luxembourg business that must create or maintain at least five local jobs.
• Investment fund or management company: A minimum of €3 million invested in or creating an investment or management structure based in Luxembourg.
• Bank deposit: A deposit of at least €20 million maintained with a Luxembourg financial institution.

Unlike some European countries, real estate investment alone does not qualify for residence, emphasizing the government’s goal of attracting productive capital rather than speculative property buyers.

Applicants must first apply for a temporary stay authorization from the Ministry of Foreign and European Affairs, then finalize residence upon arrival.

Other structural advantages make Luxembourg a preferred jurisdiction for expats and international investors:

• Financial stability: The country holds a consistent AAA credit rating, reflecting a prudent fiscal policy and stable banking sector.
• Global market access: As part of the EU, Luxembourg offers passporting rights for financial services, making it a base for cross-border fund distribution.
• Tax predictability: Transparent legislation and extensive double tax treaties (over 80 worldwide) simplify cross-border income management.
• Sophisticated fund ecosystem: Luxembourg is the second-largest fund center in the world, hosting both retail UCITS and professional alternative structures like SICARs and RAIFs.
• Quality of life: A high-income, multilingual society with strong public services and one of the EU’s most secure personal environments.

For many expats, Luxembourg’s real advantage lies in its flexibility in allowing one to maintain international investments while benefiting from one of Europe’s most secure and transparent financial environments.

Tax Residency in Luxembourg

Tax residency in Luxembourg is determined by either physical presence or center of vital interests.

Generally, anyone who stays in the country for more than six consecutive months within a tax year is deemed a resident and taxed on worldwide income. Non-residents, by contrast, are taxed only on Luxembourg-source income.

Expats can also be treated as residents under the assimilation rule if at least 90% of their income arises in Luxembourg, or if their non-Luxembourg income does not exceed €13,000 annually.

This rule benefits cross-border professionals and expatriates with limited foreign earnings, allowing them to access the same deductions and allowances as full residents.

Becoming a resident entails registering with the local commune, obtaining a social security number, and filing an annual tax return with the Administration des Contributions Directes.

Residency can be advantageous, especially when leveraging double-tax treaties or claiming joint taxation with a spouse.

Luxembourg Personal Income Tax Rate

Luxembourg has a progressive income tax system with marginal rates up to 42%, indexed periodically for inflation. For 2025, income brackets were adjusted slightly upward to offset cost-of-living increases.

Taxpayers are categorized into three tax classes:

• Class 1: Single individuals.
• Class 1a: Single parents or those over 65.
• Class 2: Married couples or registered partners (eligible for joint taxation).

Social security contributions are also mandatory, covering health insurance, pensions, and long-term care. Employers typically withhold these at source.

Filing requirements vary depending on income type and level, but as a rule, residents with multiple income sources or total earnings above €100,000 must file a return.

For most expats, Luxembourg’s clarity, moderate effective rates, and treaty network make it one of the EU’s most predictable tax systems.

Is there a wealth tax in Luxembourg?

Not for a long time. Luxembourg abolished its net wealth tax for individuals in 2006, leaving only corporations subject to the charge. This makes it particularly appealing to high-net-worth expats managing large portfolios.

Residents are not required to report personal assets such as cash, securities, or real estate for annual net wealth purposes, although they must declare income generated by those assets.

The Luxembourg Impatriate Tax Regime: A Special Tax Break for Expats

To attract foreign talent, Luxembourg offers a dedicated impatriate regime for qualified professionals who relocate at their employer’s request. Introduced in 2011 and updated in 2024, this system grants significant tax relief on relocation-related benefits and income.

Eligible expats can receive an income exemption of up to 50%, capped at €400,000 per year, for up to eight years.

Additional allowances may cover relocation expenses, temporary accommodation, and the schooling of dependent children.

A partial rental allowance introduced in 2024 further enhances its attractiveness to young professionals.

To qualify, the employee must not have been a Luxembourg tax resident in the previous five years, must earn above a defined minimum salary threshold, and must be transferred to Luxembourg by a recognized employer or international group.

The employer, in turn, must meet certain headcount or wage conditions.

The regime’s purpose is to make Luxembourg competitive with other expat destinations such as the Netherlands, Ireland, and Switzerland, offering professionals both lower effective taxation and easier integration into the country’s labor market.

For globally mobile individuals, this framework provides a balanced mix of financial incentive and legal certainty, reinforcing Luxembourg’s reputation as one of Europe’s most expat-friendly tax jurisdictions.

How are capital gains taxed in Luxembourg?

Dividends from Luxembourg companies are subject to a 15% withholding tax, which may be reduced under a double taxation treaty.

For residents, these dividends are included in taxable income, though half of the gross dividend (the 50% exemption rule) may apply in some cases, effectively reducing the burden.

Interest income from most bank deposits or bonds is typically exempt from withholding tax for residents, though it remains taxable as ordinary income.

For non-residents, interest paid by Luxembourg financial institutions is generally not subject to Luxembourg tax unless connected to a local business activity.

Capital gains taxation depends on both the size of the shareholding and the holding period:

• Gains from selling securities within six months of acquisition are treated as speculative and fully taxable.
• Gains from selling a significant shareholding (more than 10% ownership) remain taxable even after six months, with 50% of the gain included in taxable income.
• Gains from smaller holdings held for more than six months are exempt.

For cryptocurrency, Luxembourg follows the same principles. Gains from sales within six months are taxable if they exceed €500 in a year; beyond six months, crypto profits are exempt for private investors unless trading constitutes a professional activity.

Investing in Luxembourg: Investment Funds

Luxembourg is the second-largest investment fund center in the world after the United States, and expats benefit from easy access to both retail and institutional products.

For individual investors, UCITS funds offer diversified, EU-regulated exposure with high investor protection. They are ideal for expatriates who prefer liquidity and oversight.

For high-net-worth or professional investors, Luxembourg provides specialized vehicles such as:

• SIF (Specialized Investment Fund) – flexible for multiple asset classes, lightly regulated for sophisticated investors.
• SICAR (Investment Company in Risk Capital) – tailored for private equity and venture capital.
• RAIF (Reserved Alternative Investment Fund) – does not require prior CSSF approval but must appoint an AIFM, combining speed with regulatory oversight.

These fund types enjoy favorable tax treatment, with income generally exempt at the fund level and returns taxed only at the investor’s jurisdiction according to residence and treaty status.

Luxembourg’s global reputation for fund governance, stable regulation, and cross-border passporting rights makes it a key platform for expats building multi-jurisdictional portfolios.

Assurance-Vie: Luxembourg’s Signature Investment Wrapper

Luxembourg’s assurance-vie, or life insurance investment contract, is one of the most distinctive financial instruments available to expats. It combines investment flexibility with cross-border protection.

The core of the system is known as the “Triangle of Security.” This legal structure involves three parties:

1. The insurance company, which manages the policy.
2. The custodian bank, which holds the assets.
3. The Commissariat aux Assurances (CAA), the national regulator that oversees and enforces asset segregation.

Under this model, policyholders enjoy a super-privilege in case of insolvency, meaning their assets are ranked above other creditors. This strict segregation ensures that the insurer cannot access client investments for its own operations.

Assurance-vie contracts are highly customizable. Investors can choose from a wide range of underlying assets like mutual funds, bonds, equities, or alternative investments within the framework of EU insurance law.

Policies can be denominated in multiple currencies and structured for inheritance, tax planning, or expatriation scenarios.

Certain premiums and life insurance contributions may qualify for tax deductions under Luxembourg’s income tax law, depending on age, policy type, and payment structure.

While the investment growth is typically tax-deferred until withdrawal, treaty conditions and residency status determine the final tax outcome.

For high-net-worth and long-term expats, the assurance-vie serves not just as an investment tool, but as a vehicle for conservación del patrimonio, estate planning, and financial mobility—a key advantage in Luxembourg’s globally oriented financial system.

Can foreigners buy real estate in Luxembourg?

Luxembourg places no restrictions on foreign property ownership, allowing expats and non-residents to buy freely. However, demand far outpaces supply, and property prices are among the highest in Europe.

The standard registration duty is 6%, plus a 1% transcription fee, bringing total transaction costs to around 7%. Notarial fees and administrative charges add slightly more.

Mortgage terms are generally favorable, with variable or fixed rates available through local banks.

Bëllegen Akt Homebuyer Credit

To encourage home ownership, the government offers the “Bëllegen Akt” tax credit—a significant incentive for first-time or primary-residence buyers. As of 2024, the credit has been raised to €40,000 per person, or €80,000 for couples purchasing jointly.

Expats who settle permanently can also deduct mortgage interest payments and mortgage-related insurance premiums within annual limits, depending on tax class and family status.

These deductions apply only to the principal residence, not to rental or investment properties.
