How to calculate estate taxes

Tax legislation makes a distinction between two kinds of taxes on inherited assets:

  • inheritance taxes apply, in principle, to the value of all movable and immovable assets acquired or collected in the estate of a Luxembourg resident. A Luxembourg resident is any person who has established their domicile or seat of wealth there. According to the case law, a 'domicile' is defined by tax law as the place where the deceased had established their actual, effective and continuous residence, and a 'seat of wealth' is the place from which the deceased administered or supervised the administration of their assets;
  • transfer taxes are assessed on the value of immovable assets located in the Grand Duchy acquired or collected as property or usufruct from a deceased person whose most recent domicile or seat of wealth was not in Luxembourg.

Who is concerned

Inheritance or transfer taxes on inherited property are due, in principle, whether or not the heirs or legatees are resident in Luxembourg.

Preliminary steps

In order to determine the amount of inheritance or transfer taxes, heirs and universal legatees must file a declaration of inheritance or transfer on death with the Registration Duties, Estates and VAT Authority (Administration de l’enregistrement, des domaines et de la TVA - AED), which shall request the payment of the taxes due.

How to proceed

Inheritance taxes after the death of a person whose most recent domicile was in Luxembourg

If the most recent domicile of the deceased was in Luxembourg, the estate will be taxable in the Grand Duchy of Luxembourg (inheritance taxes), with the exception of real estate outside the country. No inheritance taxes will be levied on immovable property located abroad that is part of the estate of a Luxembourg resident.

Calculation of inheritance taxes

Inheritance taxes are calculated on the net value of the estate left by the deceased, also referred to as the 'net estate'.

The basis for calculating inheritance taxes is all movable assets (furniture, cars, stock, money, paintings, etc.) whether they are located in Luxembourg or abroad as well as immovable property located in Luxembourg. Under certain conditions, no inheritance taxes are levied on movable property located abroad, on which inheritance taxes are collected in the country where the property is located because of the nationality of the deceased.

The following liabilities are then deducted from the estate's assets:

  • debts existing on the date of death, such as private debts, professional debts, unpaid taxes, etc., as well as interest on them;
  • the cost of the deceased's funeral.

All assets are, in principle, valued at market value as of the date of death. However, special rules exist for the valuation of emphyteutic leases and perpetual land leases, life annuities and recurring payments, and in the case of the carving up of the property (i.e. usufruct or property without usufruct).

Example:

Publicly traded shares are valued at their market price on the day of death. Immovable assets are valued based on the probable sale value on the day of death. It may be necessary to call in an expert or determine the value by comparison with similar buildings sold recently.

If the deceased was married on the day of death, the estate includes their property and share of the joint property. The determination of separate property and joint property depends on the couple's marital arrangements.

Donations and disposals in exchange for consideration made shortly before death – Contract containing a stipulation for the benefit of a third party

In principle, inheritance taxes are not applied to assets donated or transferred by the deceased to one or more of their heirs.

Nevertheless, in certain cases, such as donations or disposals in exchange for consideration, a contract containing a stipulation for the benefit of a third party may be reinstated to calculate inheritance taxes, for example:

  • assets donated in the year prior to death not subject to registration fees for donations (including manual donations);
  • movable or immovable assets disposed of in exchange for consideration or sold by the deceased to a relative (parents, children, spouse) less than three months before death, with retention of usufruct or stipulation of abandonment of a life annuity for their benefit;
  • the value of life assurance for the benefit of a third party (a policy containing a stipulation for the benefit of a third party) constitutes an asset of the deceased's estate for the purpose of calculating estate taxes.

Inheritances exempt from inheritance taxes

Inheritances exempt from inheritance taxes include:

  • everything that is amassed or acquired in the direct descending line (from parents or grandparents to children, grandchildren, etc.) or ascending line (from grandchildren or children to parents or grandparents). The exemption is, however, limited to the legal part of the inheritance;
  • everything that is amassed or acquired between spouses or partners with one or more children born of their union or the descendants of those children;
  • everything that is amassed or acquired by the surviving spouse or partner in the estate of the spouse or partner who died first as usufruct or as a pension or recurring payment if, through the spouse or partner who died first, the children or descendants from a previous marriage or partnership have acquired the property or are responsible for the pension or recurring payment;
  • estate whose values, excluding debts, do not exceed EUR 1,250;
  • real estate located abroad and, under certain conditions, movable assets located abroad.

In order for these measures to be applicable to civil partners, they must be united under a partnership declaration registered in accordance with the provisions of Article 3 of the Law of 9 July 2004 on the legal effects of certain partnerships, at least 3 years before the commencement of the inheritance procedure.

For the calculation of inheritance taxes, an allowance of EUR 38,000 is granted on the net share collected by the spouse of a person who died first without any common children or descendants. This EUR 38,000 allowance is also granted to the surviving civil partner without any common children or descendants.

Inheritance tax rates

Inheritance taxes vary based on the family relationship between the deceased and the heir, and also the extent of the property collected.

The tax rate is calculated based on the net share collected by each heir. In order to determine the applicable rate, a distinction must be drawn between the legal portion (which is collected by the heir on the basis of the inheritance provided for by law) and the extra-legal portion (which is collected by the heir on the basis of extra-legal provisions such as wills), to which different rates apply.

Finally, the applicable rate is composed of a base rate and an increase to the base rate.

Inheritance tax base rate
  Base rate for the legal portion Base rate for the extra-legal portion
Direct line (ascending or descending) 0 % 2.5 % or 5 %*

Between spouses with common children or descendants

Between partners in a declared civil partnership registered for at least 3 years before the commencement of the inheritance procedure with common children or descendants
0 % 0 %

Between spouses with no common children or descendants

Between partners in a declared civil partnership registered for at least 3 years before the commencement of the inheritance procedure with no common children or descendants
5 %** 5 %
Between siblings 6 % 15 %
Between uncles or aunts and nephews or nieces 9 % 15 %

Between adopter and adoptee (in simple adoptions)

9 % 15 %
Between great-uncles or great-aunts and great-nephews or great-nieces 10 % 15 %

Between adopter and descendants of the adoptee (in simple adoptions)

10 % 15 %
Between all other persons 15 % 15 %

* If a direct heir receives portions to which they would not normally have been entitled, that person will have to pay a 2.5 % duty on the available share that is bequeathed to them by preference and beyond their share, and 5 % on the surplus.

** 5 % between spouses with no common children or descendants. This rate applies to all net assets collected, less an allowance of EUR 38,000.

Increases to the base rates

The basic inheritance tax rates indicated above are increased if the net taxable value of the portion collected by the beneficiary exceeds EUR 10,000. The following scale is applied:

Value of estate assets Additional tax
between EUR 10,000 and EUR 20,000

1/10

between EUR 20,000 and EUR 30,000

2/10

between EUR 30,000 and EUR 40,000

3/10

between EUR 40,000 and EUR 50,000

4/10

between EUR 50,000 and EUR 75,000

5/10

between EUR 75,000 and EUR 100,000

6/10

between EUR 100,000 and EUR 150,000

7/10

between EUR 150,000 and EUR 200,000

Example

The deceased bequeaths the entire estate to the surviving spouse. They have no common children or descendants. The total net amount of the estate is EUR 550,000. For a couple without children, the applicable basic rate is 5 %, plus 14/10 since the estate is worth EUR 550,000.

The estate may be subject to an allowance of EUR 38,000.

Taxable amount: 550,000 – 38,000 = EUR 512,000

Calculation of applicable rate:

  • base rate = 5 %;
  • increase = 14/10 (140 %);
  • applicable rate = 5 % + (5 % × 1.4) = 12 %.

Inheritance tax due: EUR 512,000 × 12 % = EUR 61,440.

Example

A family consists of 3 single brothers without children. The deceased (brother A) bequeaths the entire succession to his brother (brother B) in his will, and the other brother (brother C) inherits nothing.

The total net amount of the estate is EUR 600,000.

The following rates apply to brother (brother B), who received the entire inheritance:

Base rate:

  • On the first half, which corresponds to what he would have received as the legal portion (half the estate in this case), the brother will have to pay 6 % inheritance tax;
  • on the amount in excess of the legal portion (the other half of the estate), the brother will have to pay 15 % inheritance tax.

Increase:

14/10 (140 %)

Applicable rates:

  • on the legal portion: 6 % + (6 % × 1.4) = 14.4 %;
  • for the remainder: 15 % + (15 % × 1.4) = 36 %.

Inheritance taxes owed:

EUR 300,000 × 14.4 % = EUR 43,200

EUR 300,000 × 36 % = EUR 108,000

In principle, inheritance taxes must be paid within 6 weeks of the date of service of the request for payment by the Registration Duties, Estates and VAT Authority.

Transfer taxes after the death of a person whose most recent domicile was not in Luxembourg

If the most recent domicile of the deceased was not in Luxembourg at the time of their death, transfer taxes upon death are nevertheless levied on immovable assets located in Luxembourg.

For estates processed after 30 December 2009, transfer taxes upon death are on an equal footing with inheritance taxes. Thus, the treatment of inheritance taxes (rates, allowances, deduction of debts related to the property, etc.) applicable to the heirs or legatees of a deceased person who was not a Luxembourg resident is the same as for a deceased person whose most recent domicile was in the country.

Calculation of transfer taxes

Transfer taxes upon death are payable on the value of immovable assets located in Luxembourg. The basis for calculating the taxes is the market value of the property on the day of death less the debts related to the property.

Debts recognised as liabilities of the estate are as follows:

  • debts secured against immovable assets located in Luxembourg;
  • debts undertaken for the acquisition, improvement or conservation of immovable assets located in Luxembourg.

Other movable assets (for example, money in bank accounts) owned in Luxembourg by a deceased person whose most recent domicile was abroad shall not be subject to any Luxembourg estate tax.

Inheritances exempt from transfer taxes

Inheritances exempt from transfer taxes include:

  • everything that is amassed or acquired in the direct descending line (from parents or grandparents to children, grandchildren, etc.) or ascending line (from grandchildren or children to parents or grandparents). However, exemption is limited to the legal portion in the direct line;
  • everything that is amassed or acquired between spouses or partners with one or more children born of their union or the descendants of those children;
  • everything that is amassed or acquired by the surviving spouse or partner in the estate of the spouse or partner who died first as usufruct or as a pension or recurring payment if, through the spouse or partner who died first, the children or descendants of a previous marriage or partnership have acquired the property or are responsible for the pension or recurring payment;
  • estates whose values, excluding debts, do not exceed EUR 1,250.
In order for these measures to be applicable to civil partners, they must be united under a partnership declaration registered in accordance with the provisions of Article 3 of the Law of 9 July 2004 on the legal effects of certain partnerships, at least 3 years before the commencement of the inheritance procedure.

For the calculation of transfer taxes, an allowance of EUR 38,000 is granted on the net share amassed by the spouse of the person having died first without any common children or descendants. This EUR 38,000 allowance is also granted to the surviving civil partner without children or common descendants.

Transfer tax rates

The base rates and the increase in the base rate applicable to transfer taxes upon death are now identical to those for inheritance taxes.

The scale is as follows:
