The 3% housing VAT rate in Luxembourg: a guide for tradespeople

Short version. The super-reduced 3% VAT rate applies to the creation and renovation of a dwelling used as a main residence. Two routes exist: applying the 3% directly on your invoice, which requires approval obtained before the works, or invoicing at 17% and letting the owner claim back the 14 percentage points. The tax benefit is capped at €50,000 per dwelling. Take the wrong route and you invoice 3% without entitlement, then owe the difference.

For a Luxembourg tradesperson, housing VAT is one of the few topics where a configuration error costs real money. You invoice 3% on a job that never qualified, the Registration Duties, Estates and VAT Authority (AED) claims the missing 14 points, and your customer usually takes the view that this is not their problem. Here are the rules as written, with the thresholds and exclusions that quotes most often overlook.

Who qualifies for the 3% rate?

The amended Grand Ducal Regulation of 30 July 2002 provides for three situations, and three only, that open the right to the housing VAT benefit:

• new construction: creation, conversion of a building into a dwelling, or an extension creating new living space;
• renovation within five years of acquiring the dwelling;
• renovation of a dwelling at least twenty years old, the twenty years being counted from the date the construction was completed.

This is where most of the damage happens on the ground. A customer asks you to redo the bathroom in their fifteen-year-old house, bought eight years ago: none of the three conditions is met, and the job stays at 17%. If the same customer converts the attic and creates new living space, however, the extension counts as a creation and does qualify.

In every case the dwelling must serve as a main residence. A landlord can benefit even without knowing the tenant yet, provided they sign a written undertaking to allocate the property to main residence use and then give the authority the tenant's name and tax reference.

Direct application or refund: the two routes

You have a choice, and that choice belongs to the contracting parties. Neither you nor the customer is obliged to go through the approval procedure.

One case is worth knowing: materials bought on their own from a Luxembourg supplier (tiles, sanitaryware, flooring, wallpaper) can never be subject to direct application. The supplier always invoices at 17%, and the customer must go through the refund route.

The thresholds to keep in mind

These are what decide whether a file goes through.

Overrunning the approved quote is the classic trap on a job that drags on. You may only invoice at 3% the amount the authority has approved. If the overrun reaches or exceeds €3,000 net, file a fresh approval claim for the additional works; below that, an amendment request with the new quote is enough. Otherwise the extra goes out at 17% and the customer has to chase their refund.

What is covered, what is not

The dividing line is not intuitive. Broadly: what is built into the fabric qualifies, what counts as equipment, furniture or special technical installation does not.

The inseparable line trap

If you cannot separate the eligible from the ineligible on the invoice, the rule is blunt: you must invoice the whole at the standard 17% rate. That is the case for a sanitary set sold with its furniture, or a bath delivered with its jets. The customer then keeps the refund route, which the tax office will calculate on a flat-rate basis. Worth knowing at quoting stage: a single "complete bathroom" line costs you the direct application, whereas an itemised quote preserves it.

On the accounting side: break it down properly

An invoice mixing 3% and 17% lines must break down the taxable amount and the tax amount by rate. That is not a bookkeeper's preference, it is a mandatory detail, and it is also what an audit looks at. We set out all of those details in our article on mandatory invoice details in Luxembourg.

In practice this means three things in your management software: a 3% VAT rate properly created and mapped to the right PCN 2020 account, a product or product category carrying that rate by default so nobody guesses at entry time, and quote numbering that lets you retrieve the matching approval during an audit. An approved job whose quote has gone missing is an indefensible job. This connects to keeping accounting records for ten years, and to the FAIA audit file the AED may request.

Who this regime makes life harder for

Let us be honest: direct application is not free for the tradesperson. It requires a detailed quote, a jointly signed claim, a wait for approval before starting, and monitoring of overruns. On a small €4,000 job, many businesses prefer to invoice at 17% and let the customer claim their refund. That is a defensible choice, provided it is stated plainly in the quote rather than discovered at invoicing. A customer who expected 3% and sees 17% arrive remembers only one thing.

Frequently asked questions

What VAT rate applies to renovation in Luxembourg?

The standard rate is 17%. The super-reduced 3% rate applies only where the dwelling serves as a main residence and one of the three cases applies: new construction, renovation within five years of acquisition, or renovation of a dwelling at least twenty years old.

Does the €50,000 cap apply per person or per dwelling?

Per distinct property, identified by its cadastral reference. Once the cap is reached on a dwelling, neither the current owner nor a later buyer can still benefit from the housing VAT advantage for that property.

Must the tradesperson apply for approval?

No. The choice between direct application of the 3% rate and the refund procedure belongs to the contracting parties. Without approval, the tradesperson invoices at 17% and the owner claims back the 14 points.

What happens if the job exceeds the approved quote?

A 10% tolerance is allowed. Beyond that, if the overrun reaches €3,000 net a fresh approval claim is needed; below that, an amendment request with the new quote. Failing this, the overrun is invoiced at 17%.

Does a fitted kitchen qualify for the 3% rate?

No. Fitted kitchens, like furniture generally, white goods, curtains and blinds, are excluded from the regime, whether by direct application or by refund.
