Luxembourg is one of Europe’s most attractive jurisdictions for long-term private investors because capital gains on shares and ETFs held for more than six months are generally exempt, provided the investor does not hold a substantial participation of more than 10% (Guichet.lu, 2023; Loyens & Loeff, 2022).
At the same time, Luxembourg has a progressive personal income tax system with rates of up to 42%, plus a solidarity surcharge of 7% or 9%, depending on income level (PwC Worldwide Tax Summaries, 2026; OECD Taxing Wages, 2026). This makes Luxembourg tax-efficient for some investors, but not automatically a low-tax jurisdiction for high earners.
This guide explains the Luxembourg tax system as of 15 June 2026 for investors, expats, employees, freelancers, and digital nomads.

Tax Residency in Luxembourg
Luxembourg residents are taxed on their worldwide income, while non-residents are generally taxed only on Luxembourg-source income (PwC Worldwide Tax Summaries, 2026).
An individual is generally treated as a Luxembourg tax resident if they have a domicile or habitual abode in Luxembourg. In practice, spending more than six months in Luxembourg is a key residency indicator and is often described as the practical equivalent of the 183-day rule (Legal 500 Comparative Guide, 2026).
Where two countries could both treat someone as a resident, double tax treaty tie-breaker rules usually consider:
- Permanent home
- Centre of vital interests
- Habitual abode
- Nationality
Luxembourg has an extensive double tax treaty network, which is particularly important for investors receiving foreign dividends, interest, or employment income (PwC, 2026).
Income Tax in Luxembourg
Luxembourg uses progressive income tax rates ranging from 0% to 42% (PwC Worldwide Tax Summaries, 2026).
A solidarity surcharge applies to the calculated tax:
- 7% in most cases
- 9% for taxable income above EUR 150,000 in tax classes 1 and 1a
- 9% for taxable income above EUR 300,000 in tax class 2
These thresholds are based on the applicable Luxembourg tax rules (OECD Taxing Wages, 2026).
Luxembourg Tax Classes
Luxembourg has three main tax classes:
- Class 1: Single taxpayers
- Class 1a: Certain single parents and older taxpayers
- Class 2: Married taxpayers and qualifying civil partners
Key Income Tax Brackets for Class 1 Taxpayers
| Taxable Income | Rate |
|---|---|
| Up to EUR 13,230 | 0% |
| EUR 13,230–15,435 | 8% |
| EUR 24,255–26,550 | 14% |
| EUR 35,730–38,025 | 24% |
| EUR 54,090–117,450 | 39% |
| EUR 117,450–176,160 | 40% |
| EUR 176,160–234,870 | 41% |
| Over EUR 234,870 | 42% |
The 0% band up to EUR 13,230 functions as the practical tax-free band in the published schedule (PwC, 2026).
Luxembourg also allows deductions and credits for specific expenses, family circumstances, social security contributions, and pension-related items. Eligibility depends on the individual taxpayer’s situation.
Income Tax Example
A single employee earning EUR 60,000 does not pay 39% tax on their entire income.
Luxembourg’s progressive system taxes each portion of income at the relevant bracket rate. The solidarity surcharge is then applied to the calculated amount of tax.

Capital Gains Tax — How Luxembourg Taxes Investment Income
Tax on Stocks and ETFs
For private investors, Luxembourg’s capital gains tax rules depend mainly on:
- The holding period
- The investor’s ownership percentage
Capital gains on shares, ETFs, and similar securities are generally taxable if the assets are sold within six months of acquisition.
Where the investor holds the securities for more than six months, gains are generally exempt if the investor does not hold a substantial participation (Guichet.lu, 2023).
A substantial participation generally means holding more than 10% of a company. In this case, gains may remain taxable even after six months, although separate relief rules may apply (Loyens & Loeff, 2022; CMS, 2023).
Luxembourg also provides a small de minimis threshold. Annual speculative gains below EUR 500 are generally not taxable (Guichet.lu, 2023).
Capital Losses
Capital losses should not be treated as a general deduction for long-term investments.
The treatment of losses follows the same category-based logic as the treatment of taxable gains. In practice, losses from short-term taxable transactions may be relevant when calculating net speculative income for the year.
However, exempt long-term gains and losses that fall outside the taxable scope generally do not create a broad carry-forward deduction for ordinary private investors (Guichet.lu, 2023).
Because the treatment of losses can depend on the asset type, timing, and whether the transaction is considered speculative, investors should retain their broker statements and calculate gains and losses separately by transaction category.
Accumulating vs Distributing ETFs
Luxembourg does not appear to operate a general annual deemed-disposal or mark-to-market tax regime for ordinary ETF investors (Guichet.lu, 2023; Luxembourg investment fund guidance, 2026).
For accumulating ETFs, tax generally arises when units are sold, and only when the sale is taxable under the applicable capital gains rules.
For distributing ETFs, cash distributions are taxable investment income and must be reported where relevant.
No separate Luxembourg ETF-only tax form was identified. ETF gains, dividends, and distributions are generally reported through the standard annual tax return framework, including Model 100 where applicable (Guichet.lu, 2023).
Dividend Tax and Withholding
Luxembourg-source dividends are generally subject to a 15% withholding tax (EU Taxation & Customs, 2026).
Resident individuals may also need to include dividend income in their taxable income, subject to applicable exemptions or treaty relief.
Luxembourg rules may allow a partial exemption for qualifying dividends in specific cases, commonly described as a 50% exemption for qualifying dividend income.
However, eligibility depends on factors such as:
- The type of payer
- The investor’s status
- The applicable legal conditions
The exemption should therefore not be treated as automatic for every ETF or foreign dividend (KPMG Luxembourg; PwC, 2026).
Foreign dividends may also be subject to withholding tax in the source country. Luxembourg residents should retain evidence of foreign withholding tax so that treaty relief or foreign tax credit treatment can be assessed.

How to Report Investment Income in Luxembourg
Luxembourg investment income is generally reported through the annual income tax return, commonly known as Model 100 (Guichet.lu, 2023).
Step 1: Collect Broker Statements
Download annual reports from brokers such as:
- Interactive Brokers
- DEGIRO
- Trading 212
- Saxo Bank
- Local banks
Step 2: Calculate Gains, Losses, Dividends, and Interest
Separate short-term taxable gains from long-term exempt gains.
Track all relevant income and transactions, including:
- Dividends
- ETF distributions
- Bond interest
- Bank interest
- Foreign tax withheld
- Taxable gains and losses
Step 3: Complete the Required Tax Return Sections
Guichet.lu identifies Model 100 as the standard annual income tax return.
Gains or losses from securities held in a personal portfolio are reported in the relevant securities section.
Step 4: Submit the Return
Online filing is available through MyGuichet.
Paper filing may also be possible, depending on the taxpayer’s circumstances.
Step 5: Pay the Tax Due
The payment deadline is normally stated on the assessment notice issued by the Luxembourg tax authority.
For the 2025 tax year, the verified filing deadline is 31 December 2026 (RTL Today; NeoTax; Fiduciaire LPG, 2026).
Tax Treatment of Foreign Investments
Luxembourg residents remain taxable in Luxembourg on reportable foreign investment income, even when they use a foreign broker.
This includes income and gains from:
- Interactive Brokers
- DEGIRO
- Trading 212
- Saxo Bank
- eToro
- Foreign ETFs
- Foreign shares
- Foreign bonds
- Foreign bank interest
The research did not identify a special Luxembourg tax form solely for foreign brokers.
Instead, foreign dividends, interest, and taxable securities disposals are generally reported through the standard annual tax return (Guichet.lu, 2023).
Currency Conversion and Record-Keeping
Currency conversion is important when reporting foreign investments.
Investors should retain records showing:
- Trade dates
- Purchase prices
- Sale prices
- Dividend payments
- Withholding taxes
- Exchange rates used for reporting
Foreign financial institutions may report account information through the CRS and FATCA frameworks.
Luxembourg also adopted DAC8 rules in 2026, extending automatic exchange reporting to crypto-asset service providers (Guichet.lu; KPMG, 2026).
Other Important Taxes in Luxembourg
VAT
Luxembourg’s standard VAT rate is 17%, the lowest standard VAT rate in the EU (Taxology, 2026).
Reduced VAT rates include:
- 14%
- 8%
- 3%
The applicable rate depends on the goods or services supplied.
Property Taxes
Luxembourg applies municipal property tax to real estate.
Rates vary by commune, so property owners should verify the applicable local rules with the relevant municipality (PwC, 2026).
Rental income is generally taxable under the ordinary income tax system.
Inheritance and Gift Taxes
Luxembourg has inheritance and gift tax rules, but the applicable rates depend heavily on:
- The relationship between the deceased or donor and the beneficiary
- The type of asset
- Registration requirements
Because the applicable rate tables can be technical and case-specific, this guide does not provide a simplified universal rate table (CMS, 2023).
Family transfers, direct-line inheritances, and notarial gifts may be treated differently. Investors with cross-border estates should obtain specialist advice.
Wealth Taxes
Luxembourg does not impose a general wealth tax on individuals (PwC, 2026).
Corporate net wealth tax may apply to companies.
Local Taxes
Luxembourg applies municipal business tax to companies and local property taxes to real estate.
No general church tax applies to ordinary individual taxpayers.
Tax Advantages and Tax-Efficient Accounts
Luxembourg does not have a widely verified general-purpose retail investment wrapper equivalent to the UK ISA or the French PEA for ordinary securities investors.
However, Luxembourg offers tax-relevant pension and insurance-based arrangements.
Mandatory pension contributions form part of the social security system, while private pension or insurance products may have tax relevance depending on eligibility and product type (PwC, 2026).
For ordinary investors, Luxembourg’s most important tax advantage is usually the six-month capital gains rule for non-substantial private securities holdings.
