People plan their arrival in Luxembourg carefully and improvise their departure, which is the wrong way round. Leaving badly produces a specific set of consequences: a deposit withheld, an estimated final utility bill, a tax file left open, and a set of documents that turn out to be impossible to obtain once you are in another country. Almost all of it is avoidable with six weeks of planning and a list.

Leaving Luxembourg: the checklist people wish they had used

Three months before

One month before

The final fortnight

The deposit, and how to actually get it back

The rental deposit is the item that generates most of the complaints we hear from departing tenants, and the outcome is usually decided long before the exit inventory.

Money, tax and pensions

If you own property and are not selling

Letting a Luxembourg apartment from abroad is entirely workable and it needs a structure, not good intentions. You will need someone here to hold keys, respond to a tenant, attend the co-ownership assembly or vote by proxy, deal with the syndic and handle a leak on a Sunday. You will also have Luxembourg rental income to declare, and a non-resident tax position to manage.

Decide before you leave whether you are managing it yourself or delegating it, because arranging it afterwards, remotely, in a different time zone, is where absentee ownership goes wrong.

Documents to take with you, and why

The items below are straightforward to obtain while you are still resident and range from awkward to impossible afterwards. Collect them before the removal van arrives.

Scan everything as well as keeping the paper. Storage costs nothing and the alternative is requesting a document from an administration in a country where you no longer have an address.

Three questions we are asked

How long before I get my deposit back?

Where there is nothing to deduct and no annual reconciliation pending, within a reasonable period after the exit inventory. Where the building's charges are settled annually, part may legitimately be held until those accounts close. What matters is that the arrangement is agreed in writing at handover rather than left to good faith.

Do I have to tell the commune I am leaving?

Yes. The departure declaration is the formal closure of your residence record and it affects your tax and social security position. Leaving without it produces an administrative loose end that is much harder to resolve from another country.

Should I sell my apartment or keep it?

It depends on whether you might return, on the yield the property actually achieves after charges and management, and on your tax position as a non-resident owner. It is a calculation rather than a matter of sentiment, and it should be done with real figures before you leave rather than assumed either way.

Where we can help

If you are leaving and own an apartment here, the two live options are selling and letting, and they produce very different numbers. We handle both, and we will give you the figures for each side before you decide rather than after.

A useful editorial test for three months before is to look at the consequence rather than the headline feature.

When comparing two options on if you own property and are not selling, avoid scoring them only on the feature named in the title. For the question raised by “If you own property and are not selling”, the useful detail is not a generic list of advantages.

For the question raised by “If you own property and are not selling”, the useful detail is not a generic list of advantages.

The long-term test for documents to take with you, and why is maintenance. For the question raised by “Documents to take with you, and why”, the useful detail is not a generic list of advantages. It means pricing the effort honestly. That list can be surprisingly clarifying.

For where we can help, note what you can see, what you can measure, what you need to ask and what would be expensive to change. For the question raised by “Documents to take with you, and why”, the useful detail is not a generic list of advantages.

A stronger reading of three months before starts by asking what would change for the resident on an ordinary weekday.
