Estate and inheritance tax in Luxembourg

Inheritance tax in Luxembourg is chiefly based on two things: the size of the estate and your relationship to the deceased. Below, you can find out about all of the processes and rules involved. Topics covered include:

Luxembourg inheritance law and succession rules

Luxembourg has a system of forced heirship. This means that some relatives have a claim on an estate regardless of what is written in a will. In brief, inheritance law in Luxembourg dictates that a certain percentage of the estate must be reserved as follows:

• At least 50% to the children (if there is only one child)
• At least 66.6% to the children (if there are two children)
• A minimum of 75% to the children (if there are three or more children)

Children can waive their right to the reserved portion, but this has to be done formally in a declaration to the court registry.

Laws for surviving spouses

Surviving spouses are not protected heirs like children, but arrangements can be made through the marriage contract to ensure that spouses receive either:

• Ownership of the unreserved portion of the estate and lifetime use (usufruct) of the reserved portion
• Usufruct of the whole estate

These arrangements can only apply if the deceased’s inheriting children are also the children of the spouse. To clarify, if there aren’t any children, the whole estate goes to the surviving spouse.

Distribution of the estate

Aside from the portion of the estate reserved for forced heirship, a person may distribute the remainder of their assets as they wish.

If no will has been left, then the laws of intestate succession apply. This means that the estate would be distributed in the following order of priority:

• Children and their descendants (e.g., grandchildren, great-grandchildren)
• The surviving spouse
• Parents and their descendants (e.g., siblings, nieces/nephews)
• Grandparents and their ascendants (e.g., great-grandparents)
• More distant relatives (e.g., aunts, uncles, cousins)
• The state

When a person is survived by both their children and a spouse, the spouse has a choice between usufruct of the whole estate or ownership of the unreserved portion of the estate (not less than 25%). Registered partners are treated the same as spouses under inheritance law in Luxembourg.

The matrimonial regime between deceased and spouse determines which assets are included as part of the estate:

• Community regime (the default regime): all assets are co-owned except those acquired before the marriage or through inheritance or gift.
• Universal co-ownership regime: everything is co-owned.
• Separate ownership regime: each spouse retains sole ownership of assets.

Inheritance laws on pensions in Luxembourg

The following people may be eligible to claim a survivor’s pension in Luxembourg:

• Surviving spouse or partner
• Divorced spouse or former partner
• Relatives by blood or marriage in the direct line of descent and relatives in a collateral line up to the second degree, if the insured person dies without leaving a surviving spouse or partner
• Children of the insured individual and, where applicable, their dependent children

Civil partnerships which were formed abroad must have been registered in Luxembourg for the surviving partner or former partner to receive a survivor’s pension. If the deceased person was actively employed at the time of their death, a survivor’s pension is only available if the deceased had at least 12 continuous months of compulsory insurance over the three years preceding their death.

Furthermore, the government urges survivors to apply for the pension as quickly as possible to avoid the account being frozen.

Using the inheritance rules of your home country

If you don’t have Luxembourgish citizenship but you do have EU citizenship and want the inheritance laws of your country of nationality to apply, you must express this clearly in a will or separate declaration.

These laws will then apply as long as they don’t contravene Luxembourg’s public policy (e.g., discrimination of heirs based on gender or if born out of wedlock).

The EU rules do not apply to the following matters linked to your inheritance:

• Inheritance taxes
• Your civil status
• The property regime of your marriage/partnership (i.e., how your property should be divided after the death of your spouse/partner)
• Matters concerning companies

Luxembourg inheritance tax

Inheritance tax in Luxembourg is levied on the estate of all tax residents of Luxembourg. It is usually payable by the beneficiaries on the whole estate, with the exception of real estate owned abroad.

Movable assets abroad owned by foreign residents are also exempt if they are instead taxed in the country of nationality.

Inheritance tax rates in Luxembourg vary depending on the value of assets and the relationship between deceased and beneficiary. The rate is calculated based on the net share collected by each heir. A distinction must be made between the:

• Legal part: collected by the heir according to their capacity (e.g., children, spouse, brothers)
• Extra-legal part: collected by the heir as a result of a will, donation, etc.

The current rates include the following:

• A base rate: fixed according to the heir’s capacity
• An increase in the base rate: based on the value of the share received

Inheritance tax base rates on estates of up to €10,000

Relationship	Base rate (legal portion)	Base rate (extra-legal portion)
Direct line (ascending or descending)	0%	2.5% and/or 5%
Between spouses and civil partners*	0%	0%
Between siblings	6%	15%
Between uncles or aunts and nephews or nieces	9%	15%
Between adopter and adoptee (in simple adoptions)	9%	15%
Between adopter and descendants of the adoptee (in simple adoptions)	10%	15%
Between great-uncles or great-aunts and great-nephews or great-nieces	10%	15%
Between all other persons	15%	15%

Inheritance tax rates on estates of more than €10,000

The basic inheritance tax rates in Luxembourg are increased if the taxable value of your portion of inheritance is more than €10,000. They increase by the following amounts:

Taxable amount	Percentage increase from base rate
€10,000–€20,000	10%
€20,000–€30,000	20%
€30,000–€40,000	30%
€40,000–€50,000	40%
€50,000–€75,000	50%
€75,000–€100,000	60%
€100,000–€150,000	70%
€150,000–€200,000	80%
€200,000–€250,000	90%
€250,000–€380,000	120%
€380,000–€500,000	130%
€500,000–€620,000	140%
€620,000–€750,000	150%
€750,000–€870,000	160%
€870,000–€1,000,000	170%
€1,000,000–€1,250,000	180%
€1,250,000–€1,500,000	190%
€1,500,000–€1,750,000	200%
€1,750,000+	220%

How much inheritance tax will I pay?

The government provides the following example calculation, based on an inheritance of €550,000.

As an illustration, the applicable base rate (first table) on this inheritance is 6%, plus a 140% increase (second table) as the estate is worth €550,000. Accordingly, the rate is calculated as follows:

• Base rate: 6%
• Increase: 140%
• Applicable rate: 6% + (6% x 1.4) = 14.4%
• Inheritance tax due: €550,000 × 14.4% = €79,200

Transfer tax in Luxembourg

If the deceased’s most recent home was not in Luxembourg, the estate may instead be subject to transfer tax.

The brackets for transfer tax are identical to those for inheritance tax, though some movable assets (such as bank account funds) are not subject to transfer tax.

Paying inheritance tax in Luxembourg

The Registration Duties, Estates, and VAT Authority (Administration de l’Enregistrement et des Domaines, or AED) collects inheritance and gift taxes.

To pay inheritance tax, you’ll need to file an inheritance tax declaration. The AED assesses the declaration and sends a request for payment. The payment is then due within six weeks of the assessment finishing.

To clarify, Luxembourg has no double tax treaties with other countries for inheritance and gift tax purposes.

Reducing your inheritance tax in Luxembourg

Inheritance tax is calculated based on the total value of the real estate in Luxembourg and movable assets (such as cars, furniture, or money) anywhere in the world.

To calculate your bill, you’ll first need to deduct any liabilities from the amount inherited. To clarify, these can include any existing debts and the cost of the deceased’s funeral.

There is a tax-free allowance on small inheritances with a net value of up to €1,250. Furthermore, spouses without children have an allowance of €38,000, and charities are exempt from the tax.

Some other tax exemptions include anything acquired with a partner (and bound by a partnership declaration) at least three years before death, as well as buildings abroad.

In theory, assets gifted before death are not subject to inheritance tax. However, property donated in the year prior to death may be reinstated for tax purposes.
