Professional pension levy on lawyers' fees and the ban on turnover taxes
What is the case?
Italian law requires advocates and procuratori legali in continuous practice to belong to a national provident fund and to pay a supplementary contribution of 2% calculated on fees forming their annual VAT turnover, shown separately on the fee note and passed on to the client. Partnerships and companies pay by reference to each member's share of income, and members below a turnover threshold pay a flat minimum amount. A Milan advocate sought repayment of the contributions, arguing the levy was an unlawful turnover tax alongside VAT.
What is the Court asked?
Whether Article 33 of the Sixth Directive precludes a Member State from maintaining a compulsory professional pension contribution levied on lawyers' fees which are already subject to VAT, invoiced separately to the client alongside VAT.
The Court’s decision
Article 33 does not preclude such a contribution. It lacks the essential features of VAT. It is not general (only certain professions, and only court work), it is not always proportional to the price charged (partnership and flat-rate minimum cases), it is levied at a single stage when the fee note is issued, and no deduction is available either to the lawyer or to a taxable client. Confirms the four-limb test for identifying a prohibited turnover tax and shows how easily sector-specific levies escape it. Relevant to advisers dealing with professional body contributions, sectoral funds and parafiscal charges computed on VAT turnover.

Tax provisions ° Harmonization of laws ° Turnover tax ° Common system of value added tax ° Prohibition of collecting other national taxes having the character of turnover taxes ° Purpose ° Concept of "turnover taxes" ° Scope ° Contributions like the Italian "contributo integrativo" paid to the Lawyers' National Provident Fund ° Excluded
(Council Directive 77/388, Art. 33)
Whilst Article 33 of the Sixth VAT Directive (77/388/EEC), with the purpose of preventing the introduction of taxes, duties or charges which, through being levied on the movement of goods and services in a way comparable to VAT, would jeopardize the functioning of the common system of VAT, prohibits the maintenance or introduction of taxes which have the essential characteristics of VAT, it does not preclude the maintenance or introduction of other kinds of taxes, duties or charges which do not have those characteristics.
Consequently, Article 33 does not preclude the introduction or maintenance of a contribution like the supplementary contribution ("contributo integrativo") payable in Italy by advocates and procuratori legali to the Lawyers' National Provident Fund and calculated in principle by applying a surcharge to the earnings making up their turnover. The supplementary contribution is not a general levy; it is not always proportional to the fees payable by clients for professional services rendered and it is payable at one stage only, with no provision for deduction.

Judgment
Grounds
1By order of 14 December 1989, which was received at the Court on 28 November 1990, the Pretore di Milano (Milan Magistrate' s Court) referred to the Court for a preliminary ruling under Article 177 of the EEC Treaty a question on the interpretation of Article 33 of the Sixth Council Directive 77/388/EEC of 17 May 1977 on the harmonization of the laws of the Member States relating to turnover taxes ° Common system of value added tax: uniform basis of assessment (OJ L 145, p. 1, hereinafter "the Sixth Council Directive").
2The question was raised in proceedings between Aldo Bozzi, a member of the Milan Bar, and the Cassa Nazionale di Previdenza ed Assistenza a favore degli Avvocati e dei Procuratori Legali (Lawyers' National Provident Fund, hereinafter "the Fund") concerning rules under which a supplementary contribution ("contributo integrativo") must be paid in Italy by advocates and procuratori legali to the Fund.
3It appears from the documents before the Court that all advocates and procuratori legali who are in continuous practice in Italy are required to be members of the Fund, which was set up by Law No 6 of 8 January 1952 (Gazzetta Ufficiale della Repubblica Italiana No 16 of 19 January 1952). Contributions to the Fund and the system of benefits are governed by Law No 576 of 20 September 1980 ("Reform of the insurance scheme for the Bar", Gazzetta Ufficiale della Repubblica Italiana No 266 of 27 September 1980, hereinafter "Law No 576/1980").
4The rules governing supplementary contributions are laid down in Article 11 of Law No 576/1980. Under that provision: (a) any person whose name appears on the roll of advocates and procuratori legali, including trainees affiliated to the Fund, must pay to the Fund a certain percentage of all fees which contribute to his annual turnover for the purposes of VAT, whether or not the amount has been paid by the client; the amount concerned may be passed on to the client; (b) professional associations and companies must also pay the supplement in respect of each of their members whose name is entered on the roll of advocates and procuratori legali. The total annual amount of the compulsory contributions payable to the Fund by each member of the profession is calculated as a percentage of the turnover of the association or company equal to the percentage of the share of income received by those members; (c) every year each member must pay to the Fund as a supplementary contribution a minimum amount calculated as a percentage of the turnover equal to 15 times the minimum contribution referred to in the second paragraph of Article 10 payable in respect of the same year; (d) the percentage of the supplement is fixed at 2%; (e) the supplementary contribution is not subject to income tax or VAT and is not taken into account for the purposes of calculating professional income.
5Mr Bozzi considered that the levying of such a supplementary contribution was unlawful on the ground that it was contrary to Article 33 of the Sixth Council Directive. He therefore brought an action before the Pretore di Milano to recover the amounts paid in respect of the contribution. The Pretore di Milano decided to refer the following question to the Court for a preliminary ruling:
"Is Article 33 of the Sixth Council Directive (No 77/388/EEC of 17 May 1977) to be interpreted as precluding the application in a Member State of a requirement that lawyers pay to the Lawyers' National Provident Fund supplementary contributions based on the consideration payable by clients for their services, having regard to the fact that the consideration is already subject to VAT, the supplementary contribution is to be included separately on every invoice together with the VAT payable by the client and the contributions are used to provide insurance solely on the basis of the principle of solidarity and for all contributing lawyers, but not with regard to the individual contributors since their contributions do not count for pension purposes and cannot be reclaimed in the event that entitlement to a pension is not acquired?"
6Reference is made to the Report for the Hearing for a more detailed account of the facts of the case and in particular the provisions concerning the Fund, the procedure and the written observations submitted to the Court, which are mentioned or discussed below only in so far as is necessary for the reasoning of the Court.
7The question referred for a preliminary ruling by the national court is essentially whether Article 33 of the Sixth Council Directive precludes the introduction or maintenance of a contribution in the nature of a supplementary contribution ("contributo integrativo") payable in Italy by advocates and procuratori legali to the Fund.
8In answering that question it must be borne in mind that Article 33 of the Sixth Directive provides that "without prejudice to other Community provisions, the provisions of this Directive shall not prevent a Member State from maintaining or introducing taxes on insurance contracts, taxes on betting and gambling, excise duties, stamp duties and, more generally, any taxes, duties or charges which cannot be characterized as turnover taxes".
9The Court has consistently held (see, most recently, its judgment in Case C-200/90 Dansk Denkavit ApS and Another v Skattenministeriet [1992] ECR I-2217) that the purpose of Article 33 is to prevent the introduction of taxes, duties or charges which, through being levied on the movement of goods and services in a way comparable to VAT, would jeopardize the functioning of the common system of VAT. Taxes, duties and charges must in any event be regarded as being imposed on the movement of goods and services in a way comparable to VAT if they exhibit the essential characteristics of VAT.
10It follows that Article 33 does not preclude the maintenance or introduction of other kinds of taxes, duties or charges which do not have the essential characteristics of VAT.
11In order to determine whether the prohibition laid down in Article 33 applies to a contribution such as the supplementary contribution under consideration in the present case, it is therefore necessary to examine whether it has the essential characteristics of VAT and whether it must therefore be regarded as a turnover tax within the meaning of that term as it is used in Article 33.
12As the Court has repeatedly held (see, in particular, the judgments in Case 252/86 Bergandi v Directeur-Général des Impôts [1988] ECR 1343, paragraph 15, Joined Cases 93/88 and 94/88 Wisselink and Others v Staatssecretaris van Financiën [1989] ECR 2671, paragraph 18, Case C-109/90 Giant [1991] ECR I-1385, paragraphs 11 and 12 and in the aforementioned Dansk Denkavit case, paragraph 11), the essential features of VAT are as follows: VAT applies generally to transactions relating to goods or services; it is proportional to the price of those goods or services; it is charged at each stage of the production and distribution process; and finally it is imposed on the added value of goods and services, since the tax payable on a transaction is calculated after deduction of the tax paid on the previous transaction.
13A contribution of the kind referred to by the national court in the present case does not have the abovementioned essential features of VAT.
14First, the supplementary contribution is not a levy of a general nature. Law No 576/1980 affects only advocates and procuratori legali and the contribution provided for in Article 11 does not apply to fees for all services provided by advocates and procuratori legali since, as was explained at the hearing, it applies only to their court work. Furthermore, although it is true, as is apparent from the documents, that other liberal professions are subject to similar legislation, that is not the case with all such professions or with persons who provide a service on a commercial basis.
15Secondly, the supplementary contribution is not always proportional to the fee due from the client for the professional service. Although in principle Article 11 of Law No 576/1980 provides that the amount of the supplementary contribution should be a percentage of the consideration making up annual turnover for the purposes of VAT, that same provision nevertheless contains two important exceptions. The first concerns professional associations and companies for which it is provided that the supplementary contribution is payable as a percentage of the income received by the person concerned. It is clear that in such a case the basis on which the supplementary contribution is calculated is determined by criteria other than the price of services paid by clients. The second exception concerns members of the Fund whose turnover is less than a certain amount and who must therefore pay a minimum contribution calculated on a flat-rate basis. For that category, which represents, as emerged during oral argument before the Court, 25% of the advocates and procuratori legali affiliated to the Fund, the supplementary contribution is likewise not based on the price paid for provision of the service.
16Thirdly, unlike VAT, the supplementary contribution is payable at one stage only. It is payable only when the lawyer sends his client a statement of fees. Furthermore, there is no provision for deduction, for the lawyer bound to pay to the Fund the supplementary contribution invoiced to his clients is not entitled to make any deduction whatsoever in relation to the cost of the goods and services used in carrying out his activities. Similarly, but conversely, if the client is subject to VAT, he may deduct from the tax which he owes the input VAT paid to the lawyer but not the supplementary contribution.
17Accordingly, the reply to the question put to the Court must be that the Sixth Council Directive must be interpreted as meaning that it does not preclude the introduction or maintenance of contributions having the characteristics of the supplementary contribution ("contributo integrativo") payable in Italy by advocates and procuratori legali to the Fund.
Costs
Costs
18The costs incurred by the Italian Government and the Commission of the European Communities, which have submitted observations to the Court, are not recoverable. Since these proceedings are, for the parties to the main proceedings, a step in the action pending before the national court, the decision on costs is a matter for that court.
Operative part
On those grounds,
THE COURT (Sixth Chamber),
in answer to the question referred to it by the Pretore di Milano by order of 14 December 1989, hereby rules:
Article 33 of the Sixth Council Directive (77/388/EEC) of 17 May 1977, on the harmonization of the laws of Member States relating to turnover taxes ° Common system of value added tax, must be interpreted as meaning that it does not preclude the introduction or maintenance of contributions having the characteristics of the supplementary contribution ("contributo integrativo") payable in Italy by advocates and procuratori legali to the Cassa Nazionale di Previdenza ed Assistenza a favore degli Avvocati e dei Procuratori Legali.
Opinion of the Advocate General of 19 March 1992
Text as published by the Court on EUR-Lex, CELEX 61990CC0347.
OPINION OF ADVOCATE GENERAL JACOBS delivered on 19 March 1992 * My Lords,
1In this case, the Pretura di Milano (Milan Magistrate's Court) asks for a preliminary ruling under Article 177 of the EEC Treaty on the compatibility with Community law of contributions charged by lawyers to their clients which finance certain social benefits for members of the legal profession. It has been argued before the referring court that those contributions are incompatible with the Sixth VAT Directive, Directive 77/388 on the harmonization of the laws of the Member States relating to turnover taxes — Common system of value added tax: uniform basis of assessment (OJ 1977 L 145, p. 1).
2The question which has been referred is in the following terms:
'Is Article 33 of the Sixth Council Directive (No 77/388/EEC of 17 May 1977) to be interpreted as precluding the application in a Member State of a requirement that lawyers pay to the Lawyers' National Provident Fund supplementary contributions based on the consideration payable by clients for their services, having regard to the fact that the consideration is already subject to VAT, the supplementary contribution is to be included separately on every invoice together with the
* Original language: English.
VAT payable by the client and the contributions are used to provide insurance solely on the basis of the principle of solidarity and for all contributing lawyers, but not with regard to the individual contributors since their contributions do not count for pension purposes and cannot be reclaimed in the event that entitlement to a pension is not acquired?'
3That question has arisen in the course of proceedings instituted by Mr Aldo Bozzi, a member of the Milan Bar, against the Cassa Nazionale di Previdenza e Assistenza a favore degli Avvocati e dei Procuratori legali ('the Fund') for the recovery of LIT 2 280 390 which Mr Bozzi paid to the Fund by way of contributo integrativo, or 'supplementary contribution', under Article 11 of Law No 576 of 20 September 1980. Mr Bozzi maintains that that provision is incompatible with Article 33 of the Sixth VAT Directive, which provides as follows:
'Without prejudice to other Community provisions, the provisions of this Directive shall not prevent a Member State from maintaining or introducing taxes on insurance contracts, taxes on betting and gambling, excise duties, stamp duties and, more generally, any taxes, duties or charges which cannot be characterized as turnover taxes.'
The case turns on the question whether the supplementary contribution can be characterized as a turnover tax for the purposes of that provision.
4I note that Article 33 has recently been amended: see Directive 91/680, OJ 1991 L 376, p. 1. The amendments are not, however, material to the question raised in these proceedings.
The Fund
5The Fund was established by Law No 6 of 8 January 1952 to provide social benefits for lawyers. All lawyers practising in Italy and whose professional income reaches a certain level are required to affiliate to it. Law No 576 of 20 September 1980 is concerned with the benefits payable by the Fund, which include old-age and invalidity pensions, and with the contributions which have to be paid to it by its members. The Fund is financed by two types of contribution. The first type is the 'individual contribution', the amount of which depends on the lawyer's professional fees chargeable to income tax. The basic rate is ten per cent up to a certain ceiling. Thereafter three per cent is payable of professional income which exceeds that ceiling. There is a minimum contribution which is payable by all lawyers affiliated to the Fund. The second type of contribution is the 'supplementary contribution', which is levied at the rate of two per cent on the fees paid by clients. It is the legality of the supplementary contribution which is contested by Mr Bozzi in the main action.
6The rules relating to the supplementary contribution are laid down in Article 11 of Law No 576 of 1980. By virtue of that provision, anyone whose name appears on the roll of lawyers, including qualified lawyers who are not affiliated to the Fund and trainees who are affiliated to it, must pay to the Fund a certain proportion, currently two per cent, of all fees which contribute to his annual turnover for the purposes of VAT. The amount concerned may be, and usually is, passed on to the client, but remains payable by the lawyer to the Fund whether or not the client has paid it to the lawyer. The supplementary contribution is not subject to income tax or VAT and is not taken into account for the purposes of calculating a lawyer's professional income.
7According to Article 17 of Law No 576 of 1980, anyone whose name appears on the roll of lawyers, including trainees who are affiliated to the Fund, must inform the Fund each year of his turnover for VAT purposes. The Fund is also authorized to obtain information about lawyers' income and turnover from the tax and VAT authorities. Under Article 21 of the Law, lawyers who withdraw from the Fund before their entitlement to a pension accrues are entitled to a refund of their individual contributions, but not of their supplementary contributions. It appears that the supplementary contributions are not put to any specific purpose, but simply form part of the income of the Fund.
The concept of turnover taxes
8The meaning of the expression 'turnover taxes' in Article 33 of the Sixth Directive has been considered by the Court on a number of occasions. In view of the purpose of the directive, it would have been possible to interpret that expression widely as excluding all forms of turnover tax other than the harmonized system of VAT laid down by Community legislation. None the less, the Court's case-law, which was recently subjected to a detailed analysis by Advocate General Tesauro in Case C-200/90 Dansk Denkavit and Another v Skatteministeriet, has consistently interpreted the expression more narrowly. It would in my view be unwise, having regard to the special need for certainty in the tax field, for the Court now to depart from the general trend of its previous decisions.
9The Court made it clear in Case 252/86 Bergandi v Directeur-Général des Impôts [1988] ECR 1343, at paragraph 13, that the notion of a turnover tax for the purposes of Article 33 is a Community concept. In Joined Cases 93/88 and 94/88 Wisselink and Others v Staatssecretaris van Financiën [1989] ECR 2671, at paragraphs 17 and 18, the Court, reiterating its previous case-law, gave a detailed explanation of what that concept embraced. It stated:
'... Article 33 of the Sixth Directive, which leaves the Member States free to maintain or introduce certain indirect taxes, provided that they are not taxes which can be "characterized as turnover taxes", seeks to prevent the functioning of the common system of value-added tax from being compromised by fiscal measures of a Member State levied on the movement of goods and services and charged on commercial transactions in a way comparable to value-added tax.
... the principle of the common system of value-added tax consists, by virtue of Article 2 of the First Directive, in the application to goods and services up to the retail stage of a general tax on consumption which is exactly proportional to the price of the goods and services, irrespective of the number of transactions which take place in the production and distribution process before the stage at which the tax is charged. However, value-added tax is chargeable on each transaction only after deduction of the amount of value-added tax borne directly by the costs of the various price components. The procedure for deduction is so arranged by Article 17(2) of the Sixth Directive that taxable persons are authorized to deduct from the value-added tax for which they are liable the value-added tax which the goods have already borne.'
10Thus, only taxes which are levied in a broadly similar way to VAT are to be considered turnover taxes for these purposes. This test was applied by the Court in Case C-109/90 Giant [1991] ECR 1-1385, where it was held that a tax which was not general in scope, which was imposed at only one stage of the process of production and distribution and which was not charged on the value added since the previous transaction but on the gross amount of a taxable person's annual receipts did not constitute a turnover tax within the meaning of Article 33 of the Sixth Directive.
11However, the purpose for which the tax in question is levied is not, according to the case-law, decisive. Thus, the fact that the supplementary contribution may, as the Fund suggests, have more in common with a social security contribution than a tax does not necessarily take it outside the scope of Article 33. As Advocate General Mancini explained in somewhat similar circumstances in Case 295/84 Rousseau Wilmot v Organic [1985] ECR 3759, at p. 3761, 'it is clear that the social or fiscal purpose which the levies in question are intended to achieve does not constitute a sure and satisfactory criterion for determining whether or not such levies are covered by the Community rule'. That view was borne out by the judgment of the Court, which stated, at paragraph 16, that Article 33 of the Sixth Directive did not 'prohibit the Member States from maintaining or introducing duties or charges which are not fiscal but have been introduced specifically in order to finance social funds and which are based on the activity of undertakings or certain categories of undertakings and calculated on the basis of the total annual turnover without directly affecting the price of goods or services' (emphasis added). It is therefore apparent that such a levy was only regarded as outside the scope of the prohibition laid down in Article 33 because it possessed both the characteristics mentioned. Consequently, the purpose to which the supplementary contribution is put cannot in itself be decisive.
The status of the supplementary contribution
12The Court's judgment in Wisselink makes it clear that, in order to determine whether a charge such as the supplementary contribution constitutes a turnover tax within the meaning of Article 33 of the Sixth Directive, it is necessary to consider whether it is charged on the provision of services in a way comparable to VAT and whether it therefore jeopardizes the functioning of the common system of VAT.
13As both Mr Bozzi and the Commission point out, the supplementary contribution and VAT undoubtedly have some common features. Thus, the contribution is generally assessed on the same basis as VAT, it is exactly proportional to the cost of the service provided by the lawyer, it has a direct impact on the cost of the service and is in practice nearly always passed on to the client. Where this is the case, it will be shown separately on the lawyer's invoice in the same way as VAT.
14In my view, however, the supplementary contribution possesses a number of features which show that it is not charged on commercial transactions in a way comparable to VAT. First of all, contrary to the view put forward by the Commission, the supplementary contribution does not appear to be general in scope. It is true that the Court's case-law does not make it entirely clear what is meant by the word 'general' in this context. It might be taken to mean of general application to all goods and services, apart from certain specified exceptions, like VAT itself. Alternatively, it might have the more limited meaning of applicable generally to all goods or services falling within a particular category. But even on this narrower view, the supplementary contribution cannot in my view be considered general in scope, for Law No 576 of 1980 is concerned only with lawyers. Although it appears that a number of other liberal professions are subject to similar legislation, this is not true of all such professions and it is not suggested that others who provide a service on a commercial basis are required to pay contributions of this nature. Secondly, unlike VAT, the supplementary contribution is a single-stage charge: it is imposed only when the lawyer delivers a bill to his client. Moreover, the lawyer cannot deduct from it tax he has paid on supplies made to him, and his client cannot deduct it from tax for which he may subsequently become liable on supplies made by him.
15In my view, the Court's case-law makes it clear that those features have the effect of removing the supplementary contribution from the scope of the prohibition laid down in Article 33.
16That this is the effect of the case-law may be illustrated by comparing the supplementary contribution with the special consumption tax on passenger cars known as the BVB, which was the subject of the Court's ruling in Wisselink. There the Court said, at paragraph 20 of the judgment:
'Although the BVB is a consumption tax whose basis of assessment is proportional to the price of passenger cars, it is not a general tax since it is charged only on two categories of specific products, namely passenger cars and motorcycles. Nor is it a tax on the movement of goods and services, or a tax which is charged on commercial transactions in a way comparable to value-added tax, since it is applied once only, at the time of supply by the manufacturer or at the time of importation, and is then passed on in full at the next marketing stage without being levied anew. The BVB paid is not deductible but forms an integral part of the cost price of the car... Furthermore, the BVB does not jeopardize the functioning of the common system of value-added tax since it is levied alongside that tax and not wholly or partly in place thereof. Finally, the basis for charging the BVB is the list price of the car, net of value-added tax, and where value-added tax is payable, it is calculated on the consideration actually obtained by the supplier, including the BVB.'
The Court concluded that a tax such as the BVB did not constitute a turnover tax within the meaning of Article 33 of the Sixth Directive.
17The supplementary contribution differs in two respects from the BVB as described by the Court in the passage I have just cited. First, it is charged on the lawyer's total turnover, whereas the BVB was charged only on specific products. The supplementary contribution may therefore be considered a 'turnover tax' in the broad sense. None the less, as Advocate General Mischo acknowledged in Wisselink, at p. 2696, the Court has plainly defined that expression as it is used in Article 33 of the Sixth Directive more restrictively.
18Secondly, the supplementary contribution is not included in the consideration obtained by the lawyer on which VAT is charged. The Commission argues that the exclusion of the supplementary contribution from the basis of assessment is incompatible with Article HA(2)(a) of the Sixth Directive, which provides that the taxable amount shall include 'taxes, duties, levies and charges, excluding the value added tax itself'. According to the Commission, the supplementary contribution therefore compromises the functioning of the VAT system and must for that reason be regarded as a turnover tax for the purposes of Article 33.
Conclusion
19The Commission's view that the exclusion of the supplementary contribution from the basis of assessment is incompatible with Article 11 of the Sixth Directive may well be correct. It seems to me, however, that the answer to the question whether a tax falls within the scope of the prohibition laid down in Article 33 depends on the attributes of the tax itself. The question whether the supplementary contribution should be included in the basis of assessment is in my view a separate one. Although the Court mentioned in Wisselink that the BVB was so included, I do not think it was intending to suggest that that factor could in itself have the effect of turning a tax, duty or charge into a turnover tax for the purposes of Article 33.
20In the light of the Court's case-law, I can therefore find no relevant difference between the supplementary contribution and the BVB, the legality of which the Court upheld in Wisselink.
21I am accordingly of the opinion that the question referred by the Pretura di Milano should be answered as follows: Article 33 of the Sixth VAT Directive does not preclude the imposition by a Member State of a requirement that lawyers pay to a provident fund a supplementary contribution such as the contributo integrativo.
