Property tax in Luxembourg
What a property tax lawyer in Luxembourg actually deals with
Property in Luxembourg sits at the meeting point of civil law, notarial practice and direct taxation. A property tax lawyer in Luxembourg helps you work out which rules apply to your situation — whether you are a resident taxed on your worldwide income or a non-resident taxed only on Luxembourg-source income — and how those rules interact when a property is bought, let, mortgaged or inherited. Because the transfer of immovable property must be recorded in an authentic notarial deed to be opposable to third parties and transcribed in the mortgage register, tax questions usually arrive together with notarial and registration steps. Succession adds another layer: a declaration must generally be filed within six months of death, and EU Regulation 650/2012 may point to another country’s law. We do not advise you ourselves; we match you with a lawyer who does.
Local rules
How property tax questions work in Luxembourg
Luxembourg is a continental civil-law jurisdiction with a small, dense legal market and a very international population. The points below show which rules typically shape a property tax file here, and who is allowed to act for you.
Residents and non-residents are taxed differently
For direct taxes, a resident taxpayer is taxed on worldwide income, while a non-resident is taxed only on Luxembourg-source income. A person is treated as a resident where he or she has a fiscal domicile or habitual residence in the Grand Duchy; holding a residence permit does not by itself create tax residence. This distinction shapes almost every property tax question.
Notarial deed and the mortgage register
The transfer of real property in Luxembourg must be recorded in an authentic notarial deed to be opposable to third parties and capable of transcription in the mortgage register. The notary has exclusive competence over the acts by which immovable property changes owner. A private compromis de vente binds the parties first, but only the notarial deed secures third-party protection and mortgage registration for financing.
Inheriting property: six months and forced heirship
A succession declaration must generally be filed within six months of death. Where Luxembourg law governs, Article 913 of the Civil Code reserves part of the estate for descendants: gifts may not exceed one half with one child, one third with two and one quarter with three or more. A surviving spouse is not a forced heir but holds a statutory option.
Cross-border estates and EU Regulation 650/2012
For successions opened on or after 17 August 2015, EU Regulation 650/2012 determines the applicable law, in principle that of the deceased’s habitual residence. A testator may instead elect the law of his or her nationality to govern the whole succession, a frequent planning tool in a country with a large expatriate population. How that election interacts with forced heirship is a key point of advice.
What a dispute costs, and who may represent you
Luxembourg levies no court fees for bringing proceedings, so the main cost of a property tax dispute is lawyers’ fees, plus notaries, bailiffs and experts. There is no binding official tariff: the lawyer fixes fees under Article 38 of the Law of 10 August 1991. Legal aid may cover fees in whole or in part for those of insufficient means.
Trilingual courts and where cases are heard
Luxembourg has three administrative languages — French, German and Luxembourgish. Procedural documents must be drafted in French, though hearings may be conducted in any of the three, with court translation paid for by the State. Lesser civil claims start before the Justices of the Peace, others before the District Courts, and administrative litigation before the Administrative Tribunal.
Key time limits — Property & Real Estate Law
| Matter | Deadline and practical note | Note |
|---|---|---|
| Rent and other periodic payments (arrears) | 5 years | Applies to unpaid rent and similar periodic sums connected to a property. |
| Residential lease termination by the tenant | 3 months (6 months where the landlord relies on personal need) | Residential leases are strongly protective of tenants under the Law of 21 September 2006. |

Why people ask for help
Three situations that send people looking for a lawyer
Property tax questions in Luxembourg are rarely purely national: they mix residence, notarial formality, succession law and treaty relief.
You cannot tell which country’s rules apply
You own or inherit property in Luxembourg but live elsewhere, and it is not clear whether the Grand Duchy taxes you on it, on your worldwide income, or only on Luxembourg-source income. Do not guess.
Notarial and tax steps arrive at once
A sale, a mortgage or a gift of immovable property runs through an authentic notarial deed and the mortgage register, while tax questions sit alongside. Missing one step can delay financing or leave the transaction unprotected against third parties.
Deadlines pass quietly
A succession declaration is generally due within six months of death, an administrative appeal within three months, and a surviving spouse has three months and forty days to choose. A late file is a harder file.

A lawyer who genuinely works on property tax
We match you with a lawyer whose practice covers immovable property and Luxembourg direct taxation, so your question is handled by someone who meets these files routinely rather than occasionally.

Clarity on cost before you commit

Questions
Frequently asked questions about property tax in Luxembourg
What does a property tax lawyer in Luxembourg do?
A property tax lawyer in Luxembourg advises on how direct taxation and civil law apply to immovable property: a purchase, a letting, a transfer within the family, a mortgage, a tax notice or an inherited estate. Because transfer of real property requires an authentic notarial deed and registration in the mortgage register, tax advice and notarial steps usually advance together.
Do I pay Luxembourg tax if I live abroad and own property there?
For direct taxes, a resident taxpayer is taxed on worldwide income, whereas a non-resident is taxed only on Luxembourg-source income. A natural person is resident where he or she has a fiscal domicile or habitual residence in the Grand Duchy, and holding a residence permit does not by itself create tax residence. Bilateral treaties following the OECD model eliminate double taxation.
Do I need a notary, or a lawyer?
They do different things. Only the notary can draw up the authentic deed by which immovable property changes owner and secure transcription in the mortgage register. A lawyer advises on the tax and contractual consequences and represents you in court; lawyers are the only professionals admitted to assist and represent parties before the courts and to give legal consultations as a habitual paid activity.
Which court would hear a Luxembourg property tax dispute?
It depends on the claim. Lesser civil and commercial matters go before the three Justices of the Peace, while the District Courts of Luxembourg and Diekirch hear civil and commercial matters not expressly assigned elsewhere. Administrative litigation, such as a challenge to an administrative decision, goes to the Administrative Tribunal, with appeal to the Administrative Court.
How much does a property tax lawyer in Luxembourg cost?
Luxembourg charges no court fees to bring proceedings, so lawyers’ fees are the main cost, along with notaries, bailiffs and experts. There is no binding official tariff: under Article 38 of the Law of 10 August 1991 the lawyer fixes fees by agreement with the client. Legal aid, total or partial, may cover fees for those of insufficient means.
I am inheriting a property in Luxembourg — what matters first?
The calendar and the applicable law. A succession declaration must generally be filed within six months of death, and the surviving spouse has three months and forty days from the opening of the succession to exercise the statutory option. For successions opened on or after 17 August 2015, EU Regulation 650/2012 usually designates the law of the deceased’s habitual residence.
