Deduct a real-estate credit from your tax return in Luxembourg!

You can deduct the interest on debt from a real-estate credit from your tax return in Luxembourg

The amount of deductible interest on debt depends on whether the taxpayer has already moved into the property or not.

If the building is not yet occupied, the interest on debt is fully deductible until the taxpayer actually moves into the property.

As soon as the property is occupied by the household, the deductible amount of interest on a real-estate credit is limited and depends on the date of occupation.

Since 2023, the following deductible amounts of a real-estate credit apply in Luxembourg:

In the year of move-in and the five following years, you can deduct interest on debt in the amount of 3,000€. In the five subsequent years, you can deduct 2,250€ from your tax return, and after that 1,500€ of interests are still deductible.

This maximum amount is multiplied by the number of people in the household.

Example 1:

On May 6, 2017, two spouses purchase a house with their two minor children. To finance their house, they took out a loan on May 6, 2017, incurring an interest charge of 9,500€. They have been living in their house since the same day.

Deductible interest : 4 x 2,250€ = 9,000€.
