The first question
33
By its first question, the referring court seeks to ascertain whether Article 64(1) of Directive 2006/112 must be interpreted as meaning that a service supplied on a single occasion remunerated by way of instalment payments falls within the scope of that provision.
34
First of all, it is important to note that Article 64(1) of Directive 2006/112 must be read in the light of Article 63 of that directive, since the former is intrinsically related to the latter.
35
Article 63 of Directive 2006/112 provides that the chargeable event for VAT occurs and VAT becomes chargeable when the goods or services are supplied. Moreover, according to Article 64(1) of that directive, where the supply of services gives rise, inter alia, to successive payments, it is to be regarded as being completed, for the purposes of Article 63, on expiry of the periods to which such payments relate.
36
It follows from the combined application of those two provisions that, in respect of the supply of services giving rise to successive payments, the chargeable event for VAT occurs and VAT becomes chargeable on expiry of the periods to which those payments relate (judgment of
29 November 2018,
baumgarten sports & more
, C‑548/17, EU:C:2018:970, paragraph 28
and the case-law cited).
37
As for its interpretation, the wording ‘supplies which give rise to successive payments’ could be construed either as including one-time supplies for an agreed consideration paid in several instalments, or as concerning only supplies the nature of which justify payment in instalments, namely those which are not performed on a single occasion, but repeated or continuous over a certain period.
38
The second interpretation is borne out by the wording and purpose of Article 64(1) of Directive 2006/112. Under that provision, the liability to tax arises on expiry of the periods to which the successive payments relate. Since those payments necessarily constitute the consideration for supplies, it follows that that provision implicitly requires that the supply be completed during those periods. In those circumstances, the application of Article 64(1) of Directive 2006/112 cannot be governed solely by the successive nature of the payment for the supply.
39
Accordingly, the application of Article 64(1) is premissed on there being a relationship between the nature of the services in question and the payment in instalments, so that that provision cannot concern a one-time supply, even if paid for in instalments.
40
That literal interpretation of Article 64(1) of Directive 2006/112 is supported by its purpose and by the scheme of the directive.
41
In that regard, it should be made clear that Article 64(1) of the directive, read in conjunction with Article 63 thereof, is intended to facilitate the collection of VAT and, in particular, the ascertaining of when the liability to tax arises.
42
In order to ascertain when the chargeable event occurs and the tax becomes chargeable, Article 63 of Directive 2006/112 requires that the actual supply of a service be determined. As the Advocate General stated in point 41 of his Opinion, Article 63 does not specify which event is to be regarded as the time of supply, so that it is for the competent national authorities and courts to ascertain the time at which it actually took place.
43
By contrast, under Article 64(1) of Directive 2006/112, the chargeable event and chargeability of VAT are tied to the expiry of the periods to which the payments for the services supplied relate. Article 64(1) therefore sets out a legal rule from which the precise time of the chargeable event may be ascertained on the basis of a legal fiction, without needing to make the findings necessary for ascertaining when a service was actually supplied.
44
More particularly, as the Court has previously held, where Article 64(1) of Directive 2006/112 applies, it is sufficient that the periods of the supply of services to which the successive payments relate be mentioned in the invoices for the taxable person to satisfy the requirements of Article 226(7) of that directive, according to which the invoice must show the date on which the supply of services was made or completed (see, to that effect, judgment of
15 September 2016,
Barlis 06 – Investimentos Imobiliários e Turísticos
, C‑516/14, EU:C:2016:690, paragraphs 29 to 31
).
45
However, as a legal rule for determining the time from which a liability to tax arises, Article 64(1) of the directive applies only to the extent that the date or dates of the actual completion of services are unambiguous and potentially give rise to different interpretations, which is the case where they are, on account of their continuous or recurrent nature, supplied during one or several specific periods.
46
By contrast, as the Advocate General observed, in essence, in point 44 of his Opinion, where the time at which the supply of services is completed is unambiguous, in particular, in the event of a one-time supply and of a precise point in time from which its completion can be ascertained on the basis of the contractual relationship between the parties to the transaction, Article 64(1) of Directive 2006/112 cannot apply without disregarding the clear wording of Article 63 of that directive.
47
In addition, in accordance with the latter provision, read in the light of recital 24 of Directive 2006/112, the chargeable event and chargeability of VAT are not governed freely by the parties to the contract. On the contrary, the EU legislature thereby intended maximum harmonisation of the date on which liability to pay VAT arises in all the Member States in order to ensure the uniform collection of that tax (judgment of
2 May 2019,
Budimex
, C‑224/18, EU:C:2019:347, paragraph 22
and the case-law cited).
48
It would therefore be contrary to Article 63 of Directive 2006/112 to allow taxable persons, who have supplied a one-time service in conjunction with the conclusion of an agreement on payment of the price for that service in instalments, to opt for the application of Article 64(1) of the directive and thereby determine themselves the chargeable event and chargeability of VAT.
49
Such an interpretation of Article 64(1) of Directive 2006/112 would also prove difficult to reconcile with Article 66(a) and (b) of the directive. Under those provisions, Member States may provide, by way of derogation from Articles 63 to 65 of the directive, that VAT is to become chargeable in respect of certain transactions or certain categories of taxable person no later than the time the invoice is issued or than the time the payment is received. If taxable persons were, according to their contractual arrangements for payment of the price, able themselves, in place of the Member States, to adapt the time of the chargeable event and chargeability of VAT, Article 66(a) and (b) of Directive 2006/112 would largely be deprived of its substance.
50
Furthermore, it cannot be inferred from the case-law of the Court that Article 64(1) of Directive 2006/112 may apply even to a one-time supply of services. The cases in which the Court upheld the applicability of that provision concerned services supplied during specified periods on the basis of contracts which provided for obligations of a continuous nature, whether it be the lease of a vehicle (judgment of
16 February 2012,
Eon Aset Menidjmunt
, C‑118/11, EU:C:2012:97
), consulting services of a legal, commercial or financial nature (judgments of
3 September 2015,
Asparuhovo Lake Investment Company
, C‑463/14, EU:C:2015:542
, and of
15 September 2016,
Barlis 06 – Investimentos Imobiliários e Turísticos
, C‑516/14, EU:C:2016:690
), or agency services for the placement of a player to and in a football club (judgment of
29 November 2018,
baumgarten sports & more
, C‑548/17, EU:C:2018:970
).
51
The fact that taxable persons may ultimately pre-finance the VAT which they are required pay to the State when supplying one-time services for which the price is paid in instalments also cannot affect the conclusions in paragraphs 39 and 48 above.
52
It is the case that the Court has consistently held, in accordance with the principle of the neutrality of VAT, that the trader, as tax collector on behalf of the State, is entirely to be relieved of the burden of tax due or paid in the course of his or her economic activities, themselves subject to VAT (judgment of
15 October 2020,
E. (VAT – Reduction of the taxable amount)
, C‑335/19, EU:C:2020:829, paragraph 31
and the case-law cited).
53
However, as the Advocate General stated in point 62 of his Opinion, the role of taxable persons is not limited to that of tax collectors of VAT. In accordance with Article 193 of Directive 2006/112, the obligation to pay VAT – or, at least, output VAT – is, in principle, addressed to them when carrying out a taxable supply of goods or services, and that obligation is not subject to the prior receipt of the consideration for the supply.
54
Under Article 63 of Directive 2006/112, VAT is to become chargeable when the goods or services are supplied, that is, when the transaction in question takes place, regardless of whether the consideration due for that transaction has already been paid. Accordingly, VAT is due to the tax authorities by the supplier of goods or services, even where he or she has not yet received from his or her client the payment relating to the transaction carried out (judgment of
28 July 2011,
Commission v Hungary
, C‑274/10, EU:C:2011:530, paragraph 46
).
55
In the light of the foregoing considerations, the answer to the first question is that Article 64(1) of Directive 2006/112 must be interpreted as meaning that a service supplied on a single occasion remunerated by way of instalment payments does not fall within the scope of that provision.
The second question
56
By its second question, the referring court seeks to ascertain whether Article 90(1) of Directive 2006/112 must be interpreted as meaning that, in the case of an agreement on payment in instalments, the fact that an instalment of the remuneration has not been paid before its term must be regarded as non-payment of the price, within the meaning of that provision, and, as a result, lead to a reduction of the taxable amount.
57
It must be borne in mind that Article 90(1) of Directive 2006/112 provides for the reduction of the taxable amount in the case of cancellation, refusal or total or partial non-payment, or where the price is reduced after the supply takes place.
58
According to the case-law of the Court, in the situations covered by Article 90(1) of Directive 2006/112, that provision requires the Member States to reduce the taxable amount and, consequently, the amount of VAT payable by the taxable person whenever, after a transaction has been concluded, part or all of the consideration has not been received by the taxable person. Article 90(1) of Directive 2006/112 embodies one of the fundamental principles of that directive, according to which the taxable amount is the consideration actually received and the corollary of which is that the tax authorities may not collect an amount of VAT exceeding the tax which the taxable person received (judgment of
12 October 2017,
Lombard Ingatlan Lízing
, C‑404/16, EU:C:2017:759, paragraph 26
and the case-law cited).
59
As regards the total or partial non-payment of consideration, such non-payment cannot, contrary to rescission or annulment of the contract, return the parties to the position they were in prior to the conclusion of the contract. If there is non-payment without there being rescission or annulment of the contract, the purchaser of goods or services remains liable for the agreed price and the supplier of the goods or services in principle continues to have the right to receive payment, which he or she can rely on in court. It cannot be excluded, however, that such a debt will become definitively irrecoverable, since non-payment is characterised by the inherent uncertainty that stems from its non-definitive nature (see, to that effect, judgment of
12 October 2017,
Lombard Ingatlan Lízing
, C‑404/16, EU:C:2017:759, paragraphs 29 and 30
).
60
Thus, non-payment of the consideration, within the meaning of Article 90(1) of Directive 2006/112, applies only to those situations in which the purchaser of goods or services fails to pay, or only pays in part, a debt which it nonetheless owes under a contract for the supply of goods or services (see, to that effect, judgment of
2 July 2015,
NLB Leasing
, C‑209/14, EU:C:2015:440, paragraph 36
and the case-law cited).
61
In the light of that case-law, the fact remains that the payment of the price for a supply of services in instalments, pursuant to the contract between the parties, does not fall within the definition of non-payment of the consideration for the purposes of Article 90(1) of Directive 2006/112.
62
First, such a payment plan does not change the amount of remuneration that the taxable person is supposed to receive or actually receives. In those circumstances, the taxable amount remains unchanged and the tax authorities do not receive VAT in a greater amount than that corresponding to the taxable person’s remuneration. Second, the fact that an instalment of a fee is not due before its term cannot be regarded as a situation in which purchasers of services pay only part of the price which they owe.
63
Furthermore, as is already clear from the considerations set out in paragraphs 51 to 54 above, for the purposes of interpreting Article 90(1) of Directive 2006/112, it is irrelevant whether, in certain cases, a taxable person is required to pre-finance the VAT which he must pay to the tax authorities.
64
In the light of the foregoing considerations, the answer to the second question referred is that Article 90(1) of Directive 2006/112 must be interpreted as meaning that, in the case of an agreement on payment in instalments, the fact that an instalment of the remuneration has not been paid before its term cannot be regarded as non-payment of the price, within the meaning of that provision, and, as a result, cannot lead to a reduction of the taxable amount.
