The situations triggering clawback
Four situations, all foreseeable.
Not occupying the property within the applicable limit, two years as a rule, four years for a building plot or a property under construction.
Leaving the property before the end of the uninterrupted occupation period of two years.
Putting the property, even partly, to another use, notably by letting part of it.
Disposing of the property before the end of the commitment period.
None of these four presupposes any fraudulent intent. A change in professional or family circumstances can lead to them, which makes knowing the rules all the more useful.
| Situation | Effect | Obligation |
|---|---|---|
| Change of use | Loss of the benefit | Report without delay |
| Letting the dwelling | Loss of the benefit | Report without delay |
| Resale before the end of the undertaking | Repayment possible | Report and enquire |
| Temporary justified absence | No automatic loss | Keep proof of the ground |
The obligation to declare
This is the least known obligation, and it stands on its own. It requires any change of use to be reported.
The purchaser undertakes to declare in writing to the competent administration, within three months, any disposal or any change of use of the property concerned.
That obligation falls on the beneficiary, not on the notary or a third party.
It applies even where the beneficiary considers the situation does not call the credit into question, assessment being for the administration.
Failing to declare turns a difficulty into a breach, which closes off amicable routes.
What non-compliance costs
Two consequences, cumulative.
Repayment of the amount of the relief, in the event of non-compliance with the conditions.
Default interest may be added, according to Luxembourg professional sources.
The clawback bears on the whole of the benefit, not on a fraction corresponding to the period not observed.
That completeness matters for assessing risk: a breach occurring late in the commitment period costs as much as an immediate one.
What is not a forfeiture
Two reassuring and useful clarifications. They concern cases that do not forfeit the benefit.
A resale after the occupation conditions have been satisfied does not trigger restitution. The undertaking having been kept, the benefit is definitively acquired.
By contrast, the credit used is not restored for a new purchase. The personal counter does not reset, covered in the article on the tax credit.
Particular situations may be assessed differently, notably where departure results from circumstances beyond the person's control. Such situations fall to the administration and not to a personal reading of the texts.
What to do when circumstances change
Four reflexes, in this order.
Declare within three months, without waiting to find out whether the credit is actually called into question.
Check whether an extension of the occupation limit is available, where the breach is late occupation rather than a disposal.
Document the circumstances, particularly where they are outside your control.
Consult the notary or the administration before taking an irreversible decision, such as letting.
What this means for a professional
Four rules.
Flag the three-month obligation to declare, which almost all beneficiaries do not know.
Warn before any letting, even partial, during the commitment period.
Recall that clawback is total, which changes the assessment of risk late in the period.
Direct people to the administration for circumstances beyond their control, rather than presuming tolerance.
