VAT option on a commercial lease in Luxembourg

How does the VAT option on a commercial lease in Luxembourg work?

The VAT option on a commercial lease in Luxembourg lets the landlord waive the exemption covering the letting of immovable property, charge tax on the rent and deduct the VAT borne on the building, provided the tenant uses that building, entirely or as to its predominant part, for activities that themselves carry a right of deduction.

The mechanism is a single switch. Without the option, rent is exempt and the VAT paid on acquisition, construction or refurbishment stays permanently with the landlord, who passes it into the rent without being able to name it. With an approved option, rent becomes taxable, the taxable tenant recovers that tax like any other cost, and the landlord opens a right of deduction on the building.

Both sides therefore gain, which is why the option is negotiated when the lease is drawn up rather than afterwards. One feature deserves stating at the outset: the option is the landlord's decision, whereas the condition making it available is assessed in the tenant's hands. The landlord thus depends on a situation it does not control and which may change during the lease.

Why is the letting of immovable property exempt by default?

The letting of immovable property is exempt from VAT in Luxembourg under article 44(1) of the amended law of 12 February 1979, whose points f) and g) cover the supply of immovable property together with its leasing and letting. Exemption is the rule, and the option is the exception.

Article 45 of the same law opens that exception in narrow terms: any taxable person carrying out operations referred to in article 44(1)(f) and (g) for another taxable person may, within the limits and subject to the conditions to be determined by grand-ducal regulation, waive the exemption provided for there. Three boundaries sit in that one sentence. The operation must take place between taxable persons, the waiver is not available as of right, and its limits are referred to a regulation.

Luxembourg's choice sits inside a European faculty, and that explains its shape. Article 135(1)(l) of Directive 2006/112/EC requires Member States to exempt the leasing and letting of immovable property; article 137(1)(d) allows them to grant their taxable persons a right to opt for taxation of those same letting operations. Paragraph 2 of the same article leaves them to lay down the detailed rules governing exercise of the option and permits them to restrict its scope. The 1980 grand-ducal regulation is precisely that national margin being exercised.

One operation escapes the debate altogether. Acquiring a building yet to be built is subject to VAT as a matter of law in Luxembourg, with no option required: it is the letting and the sale of an existing building that fall under the exemption and therefore under the option regime. Whether the landlord is a taxable person at all is settled earlier, on VAT registration.

What conditions must the tenant meet for the option to be available?

The tenant must use the building, entirely or as to its predominant part in the case of mixed use, for activities carrying a right of deduction: that is the central condition laid down in Luxembourg by the grand-ducal regulation of 7 March 1980. That text sets both the limits and the conditions.

Mixed use receives a broad definition in that text: there is mixed use whenever the building is not entirely assigned to the exercise of such activities. A single floor let to a medical practice, whose services are exempt, is therefore enough to move an office building into mixed use, even where the rest of the building is occupied by fully taxed activities.

Two consequences follow from that definition, and they pull in opposite directions. Where the option is available for a mixed-use building, it covers the whole building: the landlord cannot opt floor by floor. Yet input tax may be deducted only to the extent the assignment allows, so a total option does not carry total deduction. The computation then rejoins the general machinery of input deduction and the pro rata.

No percentage appears in the text of the regulation as we were able to read it, and we therefore advance none. The benchmark of half the input tax, met on explanatory pages, was not found in the regulation itself: the only enforceable notion there is the predominant part, which the authority assesses on the file before it.

How is the authority's approval obtained for a commercial lease?

Approval is obtained in Luxembourg on a written option declaration submitted to the Administration de l'enregistrement, des domaines et de la TVA, which has one month from the filing of the request to grant or refuse the possibility of waiving the exemption.

The indirect tax portal publishes two separate forms, one for sales and one, headed "Option Location", for leases. That distinction is not cosmetic: the two regimes are not triggered at the same moment. For a sale for consideration, approval must be obtained before the authentic deed is executed, which places the option on the critical path of the notarial timetable. For a lease, approval also requires the contract to be registered with the authority within three months.

The effective date deserves particular attention, because it is not negotiable. Tax may be charged from the first day of the month following the month in which the option declaration was approved. A lease starting on 1 March whose option is approved on 20 March therefore produces exempt rent in March and taxable rent from 1 April, with no catching up on that first month.

One formal obligation completes the regime: separate accounting records must be kept for immovable property operations. Far from a formality, that requirement is what makes the deduction demonstrable in an audit, and it is prepared at the point where rent enters the VAT returns.

What the option changes for the landlord's deduction

The landlord's deduction follows the option in Luxembourg: once approval is obtained, the VAT borne on acquiring, constructing and maintaining the building becomes deductible, but only to the extent the declared assignment allows.

A building under construction shows the price of late approval. Input tax may be deducted by the owner only from the approval of the option declaration, save for prior administrative authorisation. A site started before any filing therefore runs a gap between contractors' invoices arriving and a right of deduction not yet open, and prior authorisation exists precisely to avoid it.

The transaction also remains an immovable property transaction, and its legal structure governs its treatment. The choice of vehicle holding the building, the split between property company and operating company, and the treatment of tenant works are all settled before the lease, as part of a real estate structuring consistent with the option contemplated.

What happens if the use of the building changes?

A change in the use of the building puts the option in question in Luxembourg and opens an adjustment of the tax deducted, spread over ten years for immovable capital goods, at one tenth per calendar year or part of a year.

The machinery is that of capital goods, and it is not specific to the option: the period is five years for movable goods, in fifths, and ten years for a building, in tenths. The global computation for the time left to run, the user's duty to declare any change on pain of forfeiture and the threshold below which no adjustment is due are set out in our article on adjusting input tax on capital goods.

What the option adds to that regime is the identity of whoever sets the event in motion. VAT circular no. 796 of 9 October 2019 expressly notes that a change of circumstances making previously taxed operations exempt may reach the landlord of a building let to a taxable person whose operations become exempt. Put plainly, a shift in the tenant's business — a licence lost, a new exempt activity, a sale of the business — can bring down the condition of the option and open an adjustment in the landlord's hands.

A European limit nevertheless constrains what national law may make of the option. Ruling on article 137(2) of the directive, the Court of Justice of the European Union held, in an order made in 2020 in case C-248/20, that the provision precludes national legislation which in fact revokes the right of deduction acquired through exercise of the option. Member States may frame the option; emptying of its content the deduction it has opened is another matter.

The practical reach is a decade of dependence. A landlord who has deducted the VAT on acquisition or construction stays exposed, until the ten-year period expires, to a decision taken inside its tenant's business, and about which nothing informs it if the lease made no provision.

What we regularly see in commercial lease files

Commercial lease files in Luxembourg regularly founder on the timetable of the option rather than on the substance of the regime, and the difficulty is entirely avoidable because the one date that matters is known in advance. The option is considered after the lease is signed, sometimes after the first rent has been invoiced, whereas tax may only be charged from the month following approval: rent already invoiced stays exempt, and the matching input VAT cannot be recovered.

Another recurring feature is a lease clause silent on use. The contract describes the permitted use in commercial terms, without committing the tenant on whether its activity carries a right of deduction or on any duty to report a change. Yet the tenant bears the annual reporting obligation and the landlord bears the adjustment: a lease creating no information duty between them leaves that risk unmonitored.

A last point recurs in shared buildings. Mixed use is assessed on the building as a whole, so the arrival of a single exempt tenant alters the position of every other lease in the same building. Tracking the tenant mix year by year is not excessive caution: it is the only way to know whether the condition of the option still holds.

Three points could not be verified and are therefore not asserted here. First the primary texts themselves: the Luxembourg official domains are blocked by the network proxy of our editorial environment, and these pages were read through indexed extracts obtained from searches restricted to official domains, with no extrapolation. Second the quantified threshold of the predominant part, absent from the regulation as we were able to read it: the benchmark of half the input tax comes from an explanatory page and is not reproduced here as a rule.

Third the exact numbering of the articles of the 1980 regulation carrying the adjustment rules, the extracts read being truncated on that point. You can confirm each of those points against the consolidated version published on Legilux and, for the practice applicable to your file, by a written request to the Administration de l'enregistrement, des domaines et de la TVA.

This article sets out the state of the law at the date of publication and is not personalised advice: whether the option is available depends on the actual use of the building, on the tenant's status and on the timetable of the transaction, and is settled with your licensed accountant.
