The dispute in the main proceedings and the question referred for a preliminary ruling

| 26 | Mr Wächtler, a German national, has since 1 February 2008 been the managing director of a company incorporated under Swiss law, the nature of his business being in the field of IT consultancy, and he owns 50% of the company’s share capital. |

Mr Wächtler, a German national, has since 1 February 2008 been the managing director of a company incorporated under Swiss law, the nature of his business being in the field of IT consultancy, and he owns 50% of the company’s share capital.

| 27 | On 1 March 2011 Mr Wächtler transferred his domicile from Germany to Switzerland. Following that transfer, the Finanzamt Konstanz, pursuant to Paragraph 6 of the AStG and Paragraph 17 of the EStG, levied income tax on the unrealised capital gain with respect to his shareholding in that company. |

On 1 March 2011 Mr Wächtler transferred his domicile from Germany to Switzerland. Following that transfer, the Finanzamt Konstanz, pursuant to Paragraph 6 of the AStG and Paragraph 17 of the EStG, levied income tax on the unrealised capital gain with respect to his shareholding in that company.

| 28 | Since Mr Wächtler considered that that taxation, liability for which arises solely because he has transferred his domicile to Switzerland, is contrary to the AFMP, and more specifically to the right of establishment provided for by the AFMP, he brought an action before the Finanzgericht Baden-Württemberg (Finance Court, Baden-Württemberg, Germany). |

Since Mr Wächtler considered that that taxation, liability for which arises solely because he has transferred his domicile to Switzerland, is contrary to the AFMP, and more specifically to the right of establishment provided for by the AFMP, he brought an action before the Finanzgericht Baden-Württemberg (Finance Court, Baden-Württemberg, Germany).

| 29 | That court has doubts as to the compatibility of the tax regime at issue with the preamble of the AFMP, with Articles 1, 2, 4, 6, 7, 16 and 21 thereof, and with Article 9 of Annex I thereto, in that it prescribes the taxation of unrealised capital gains with respect to company shares while permitting no deferral of payment of the tax payable in the event of a transfer, by a national of the Member State concerned, of his domicile to Switzerland, whereas, in the event of a transfer, by such a national, of his domicile to a Member State other than the Federal Republic of Germany or to a third State that is a party to the EEA Agreement, that tax regime does permit deferral, without interest and without provision of any guarantee, of payment of such a tax until the actual disposal of the shareholdings concerned, provided that, first, the host State gives to the Federal Republic of Germany assistance and support in tax recovery and, second, the tax payer is subject in that host State to taxation comparable to the German income tax liability. |

29

That court has doubts as to the compatibility of the tax regime at issue with the preamble of the AFMP, with Articles 1, 2, 4, 6, 7, 16 and 21 thereof, and with Article 9 of Annex I thereto, in that it prescribes the taxation of unrealised capital gains with respect to company shares while permitting no deferral of payment of the tax payable in the event of a transfer, by a national of the Member State concerned, of his domicile to Switzerland, whereas, in the event of a transfer, by such a national, of his domicile to a Member State other than the Federal Republic of Germany or to a third State that is a party to the EEA Agreement, that tax regime does permit deferral, without interest and without provision of any guarantee, of payment of such a tax until the actual disposal of the shareholdings concerned, provided that, first, the host State gives to the Federal Republic of Germany assistance and support in tax recovery and, second, the tax payer is subject in that host State to taxation comparable to the German income tax liability.

| 30 | That court states that that deferral, with respect to the second scenario involving transfer of domicile, was introduced in Paragraph 6(5) of the AStG by the national legislature because, if there were no possibility of deferring payment of the tax at issue, the tax regime concerned would be in breach of the freedom of establishment guaranteed by EU law, since a German national who maintains his domicile in the national territory is taxed only at the time when the capital gains with respect to the shares concerned are realised. The compatibility with EU law of the amendment made to that provision in relation to the deferral of recovery was, it is added, confirmed by the judgment of 11 March 2004, de Lasteyrie du Saillant (C‐9/02, EU:C:2004:138). |

| 31 | If the tax regime at issue were to constitute a restriction on the right of establishment within the meaning of the AFMP, the referring court is uncertain whether that restriction can be justified by overriding reasons in the general interest, linked to the preservation of the allocation of powers of taxation between the contracting parties concerned, the effectiveness of fiscal supervision and the need to ensure the effective collection of the tax in order to prevent loss of tax revenue and, if that is the case, whether that restriction is appropriate for attaining the objective pursued and does not go beyond what is necessary in order to attain it. |

| 32 | In those circumstances, the Finanzgericht Baden-Württemberg (Finance Court, Baden-Württemberg) decided to stay the proceedings and to refer the following question to the Court of Justice for a preliminary ruling:
  ‘Must the provisions of the [AFMP], in particular the preamble and Articles 1, 2, 4, 6, 7, 16 and 21 thereof and Article 9 of Annex I thereto, be interpreted as precluding the legislation of a Member State which, in order to prevent any loss of the tax base, prescribes the taxation (without deferral) of latent, unrealised capital gains with respect to company shares, where a national of that Member State, initially subject to unlimited tax liability in that Member State, transfers his domicile from that Member State to Switzerland, and not to a Member State ... or to a State to which the EEA Agreement is applicable?’ |

In those circumstances, the Finanzgericht Baden-Württemberg (Finance Court, Baden-Württemberg) decided to stay the proceedings and to refer the following question to the Court of Justice for a preliminary ruling:

Consideration of the question referred

Consideration of the question referred

| 33 | As stated in paragraph 30 of the present judgment, the possibility of deferring the payment of tax relating to unrealised capital gains with respect to company shares, in the event that a German national transfers his domicile to a Member State other than the Federal Republic of Germany or to a third State that is party to the EEA Agreement, was introduced by the national legislature in order to bring the German tax regime into compliance with EU law on the free movement of persons, since a German national who maintains his domicile in the national territory is taxed on the capital gains with respect to company shares only at the time when those gains are realised. |
| --- | --- |

33

As stated in paragraph 30 of the present judgment, the possibility of deferring the payment of tax relating to unrealised capital gains with respect to company shares, in the event that a German national transfers his domicile to a Member State other than the Federal Republic of Germany or to a third State that is party to the EEA Agreement, was introduced by the national legislature in order to bring the German tax regime into compliance with EU law on the free movement of persons, since a German national who maintains his domicile in the national territory is taxed on the capital gains with respect to company shares only at the time when those gains are realised.

| 34 | Consequently, the question of the referring court has to be understood as seeking, in essence, to ascertain whether the provisions of the AFMP must be interpreted as precluding a Member State’s tax regime which, in a situation where a natural person, who is a national of that Member State and who pursues an economic activity in the territory of the Swiss Confederation, transfers his domicile from the Member State whose tax regime is at issue to Switzerland, prescribes the collection, at the time of that transfer, of the tax payable on the unrealised capital gains with respect to company shares owned by that person, whereas, in the event that domicile is maintained in that Member State, the collection of the tax takes place only at the time when the capital gains are realised, that is when there is a disposal of the company shares concerned. |

| 35 | As a preliminary point, since the AFMP is an international treaty, it must be interpreted, in accordance with Article 31 of the Vienna Convention on the Law of Treaties of 23 May 1969 (United Nations Treaty Series, vol. 1155, p. 331), in good faith, in accordance with the ordinary meaning to be given to its terms in their context and in the light of its object and purpose (judgments of 2 March 1999, Eddline El-Yassini, C‐416/96, EU:C:1999:107, paragraph 47, and of 24 November 2016, SECIL, C‐464/14, EU:C:2016:896, paragraph 94 and the case-law cited). Further, it follows from that provision that a term will be understood to have a special meaning if it is shown that that was the intention of the parties (see, to that effect, judgment of 27 February 2018, Western Sahara Campaign UK, C‐266/16, EU:C:2018:118, paragraph 70). |

| 36 | In that context, it is important to note, first, that the AFMP falls within the more general framework of relations between the European Union and the Swiss Confederation. Although the Swiss Confederation does not participate in the European Economic Area and in the European Union’s internal market, it is nevertheless linked to the European Union by numerous agreements covering vast fields and prescribing specific rights and obligations, analogous, in some respects, to those laid down by the Treaty. The general objective of those agreements, including the AFMP, is to strengthen the economic ties between the European Union and the Swiss Confederation (judgment of 6 October 2011, Graf and Engel, C‐506/10, EU:C:2011:643, paragraph 33). |

| 37 | However, as the Swiss Confederation has not joined the internal market of the European Union, the interpretation given to the provisions of EU law concerning that market cannot automatically be applied to the interpretation of the AFMP, unless there are express provisions to that effect laid down by that agreement itself (judgment of 15 March 2018, Picart, C‐355/16, EU:C:2018:184, paragraph 29). |

| 38 | As regards, second, the objective of the AFMP and the interpretation of its terms, it is clear from the preamble, Article 1 and Article 16(2) of the AFMP that the aim of that agreement is to secure, for natural persons who are EU nationals or nationals of the Swiss Confederation, the free movement of persons in the territory of those parties based on the rules applying within the European Union, the terms of which must be interpreted in accordance with the relevant case-law of the Court prior to the date of signature of that agreement. |

| 39 | As regards case-law after that date, it must be noted that Article 16(2) of the AFMP provides, first, that that case-law must be brought to the attention of the Swiss Confederation and, second, that, in order to ensure that the AFMP works properly, at the request of a Contracting Party, the Joint Committee provided for in Article 14 of the AFMP is to determine the implications of such case-law. That said, even where no determination is made by that committee, as stated by the Advocate General in points 71 and 72 of his Opinion, that case-law should also be taken into account in so far as it does no more than clarify or confirm the principles established in the case-law in existence on the date of signature of the AFMP in relation to concepts of EU law which inform that agreement. |

According to the preamble and Article 1(a) and (c) of the AFMP, the scope of that agreement extends both to natural persons who pursue an economic activity and those who do not do so.

| 43 | As regards, more particularly, such a person, it is stated in the wording of Article 1(a) of the AFMP that the objective of that agreement is to accord a right of entry, residence, access to work as an employed person, establishment on a self-employed basis and the right to stay in the territory of the Contracting Parties. To that end, Article 4 of the AFMP provides that the right of residence and access to an economic activity is to be guaranteed in accordance with the provisions of Annex I to that agreement. |

As regards, more particularly, such a person, it is stated in the wording of Article 1(a) of the AFMP that the objective of that agreement is to accord a right of entry, residence, access to work as an employed person, establishment on a self-employed basis and the right to stay in the territory of the Contracting Parties. To that end, Article 4 of the AFMP provides that the right of residence and access to an economic activity is to be guaranteed in accordance with the provisions of Annex I to that agreement.

| 44 | As regards the capacity in which the economic activity concerned is pursued, it is clear from a comparison of Articles 6 and 7 of Annex I to the AFMP with Articles 12 and 13 of that annex that the distinction made between employed persons and self-employed persons is linked to the question of whether the economic activity in question is to be regarded as ‘activity as an employed person’ or as ‘self-employed activity’. |

As regards the capacity in which the economic activity concerned is pursued, it is clear from a comparison of Articles 6 and 7 of Annex I to the AFMP with Articles 12 and 13 of that annex that the distinction made between employed persons and self-employed persons is linked to the question of whether the economic activity in question is to be regarded as ‘activity as an employed person’ or as ‘self-employed activity’.

| 45 | In that context, it must be recalled that the concept of an ‘employed person’ is a concept of EU law (judgment of 19 March 1964, Unger, 75/63, EU:C:1964:19, p. 363) which already existed at the date of signature of the AFMP. The essential feature of an employment relationship is that, for a certain period of time, a person performs services for and under the direction of another person in return for which remuneration is received. Conversely, an activity pursued without any relationship of subordination has to be classified as ‘self-employed activity’ (see, by analogy, judgments of 27 June 1996, Asscher, C‐107/94, EU:C:1996:251, paragraphs 25 and 26, and of 20 November 2001, Jany and Others, C‐268/99, EU:C:2001:616, paragraph 34). |

| 46 | Since Mr Wächtler pursues his activities as an IT Consultant by means of a company of which he is the managing director and of which he owns 50% of the shares, the relationship of subordination which characterises activity as an employed person is, in this case, absent, as the Advocate General stated in points 38 and 39 of his Opinion. It follows that the economic activity pursued by Mr Wächtler is that of a self-employed person, within the meaning of the AFMP. |

It follows that the economic activity pursued by Mr Wächtler is that of a self-employed person, within the meaning of the AFMP.

| 47 | As regards the scope ratione personae of the concept of ‘self-employed person’, within the meaning of the AFMP, the Court has already stated that that scope is defined in Articles 12 and 13 of Annex I to that agreement (judgment of 15 March 2018, Picart, C‐355/16, EU:C:2018:184, paragraph 18). |

ratione personae

| 48 | It follows from Article 12(1) of that annex that that provision is applicable to a natural person who is a national of a contracting party and who has become established in the territory of another contracting party and pursues a self-employed activity in the territory of that other party (see, to that effect, judgment of 15 March 2018, Picart, C‐355/16, EU:C:2018:184, paragraphs 22 and 23). |

| 49 | Mr Wächtler’s situation is that of a national of a contracting party of the AFMP, namely the Federal Republic of Germany, who has become established in the territory of another contracting party, namely the Swiss Confederation, in order there to pursue, by means of a company, his self-employed activity. That situation falls, therefore, within the scope of Article 12 of Annex I to the AFMP. |

Mr Wächtler’s situation is that of a national of a contracting party of the AFMP, namely the Federal Republic of Germany, who has become established in the territory of another contracting party, namely the Swiss Confederation, in order there to pursue, by means of a company, his self-employed activity. That situation falls, therefore, within the scope of Article 12 of Annex I to the AFMP.

| 50 | The fact that Mr Wächtler owns 50% of the shares in the company by means of which he pursues the self-employed activity in question cannot call that finding into question. As the Advocate General stated, in essence, in points 43 to 56 of his Opinion, the right of establishment as a self-employed person, within the meaning of the AFMP, extends, with the exception of the provision of services, to any economic or gainful activity of a natural person that can be classified as a ‘self-employed’ activity. Moreover, the actual exercise of that right presupposes the possibility of choosing the legal form that is appropriate to doing so. |

| 51 | As regards whether it is open to a national of a contracting party to assert the rights conferred by the AFMP against his or her State of origin, it must be observed that, in accordance with case-law of the Court which existed prior to the date of signature of that agreement, the right of establishment, within the meaning of EU law, has the aim not only of ensuring that foreign nationals are treated in the host Member State in the same way as nationals of that State, but also of preventing restrictions on that right issuing from the Member State of origin of the national concerned (see, to that effect, judgment of 27 September 1988, Daily Mail and General Trust, 81/87, EU:C:1988:456, paragraph 16). |

| 52 | Accordingly, in certain circumstances and in the light of the applicable provisions, nationals of a Contracting Party of the AFMP may claim rights under that agreement not only against the State to which they exercise freedom of movement but also against their State of origin (judgment of 15 March 2018, Picart, C‐355/16, EU:C:2018:184, paragraph 16 and the case-law cited). |

| 53 | The free movement of persons guaranteed by the AFMP would be impeded if a national of a Contracting Party were to be placed at a disadvantage in his State of origin solely for having exercised his right of free movement (judgment of 15 December 2011, Bergström, C‐257/10, EU:C:2011:839, paragraph 28). |

| 54 | It follows that the principle of equal treatment, laid down in Article 15(2) of Annex I to the AFMP, read together with Article 9 of that annex, can also be relied on against his State of origin by a self-employed person who falls within the scope of that agreement. |

Since the principle of equal treatment is a concept of EU law (see, to that effect, judgments of 19 October 1977, Ruckdeschel and Others, 117/76 and 16/77, EU:C:1977:160, paragraph 7, and of 6 October 2011, Graf and Engel, C‐506/10, EU:C:2011:643, paragraph 26 and the case-law cited) which existed at the date of signature of the AFMP, it is necessary, as follows from paragraphs 38 and 39 of the present judgment, to take into account the principles established by the Court’s case-law in relation to equal treatment in order to determine whether there is any discrimination that is prohibited by the AFMP (see, to that effect, judgments of 6 October 2011, Graf and Engel, C‐506/10, EU:C:2011:643, paragraph 26, and of 21 September 2016, Radgen, C‐478/15, EU:C:2016:705, paragraph 47).

| 56 | In this case, it is clear that a German national who, like Mr Wächtler, has exercised his right of establishment as a self-employed person under the AFMP suffers a fiscal disadvantage as compared with other German nationals who, like him, pursue a self-employed activity by means of a company in which they own shares, but who, unlike him, maintain their domicile in Germany. That is because the latter have to pay the tax on the capital gains with respect to the shares concerned only when those capital gains are realised, that is when there is a disposal of those shares, whereas a national such as Mr Wächtler is obliged to pay the tax at issue, at the time when he transfers his domicile to Switzerland, on the unrealised capital gains with respect to such shares, and has no right to a deferral of payment until the disposal of those shares. |

| 57 | That difference in treatment, which constitutes a tax-flow disadvantage for a German national such as Mr Wächtler, is capable of deterring him from making actual use of the right of establishment he derives from the AFMP. It follows that the tax regime at issue in the main proceedings may impede the right of establishment as a self-employed person guaranteed by that agreement. |

| 58 | It must, however, be noted that the effect of Article 21(2) of the AFMP is that taxpayers whose situations are not comparable, especially as regards their place of residence, may be treated differently for tax purposes (judgment of 21 September 2016, Radgen, C‐478/15, EU:C:2016:705, paragraph 45). |

| 59 | In that regard, it must be stated that, under Paragraph 6 of the AStG, the Federal Republic of Germany decided to exercise its powers to tax capital gains, with respect to shares owned by a German national, which have accrued during the period when that national, being domiciled in Germany, is subject to an unlimited liability to the German tax, irrespective of the territory where those capital gains accrued. |

| 60 | Having regard to the objective of that legislation, which is to tax the capital gains on shares which have accrued within the scope of the tax powers of the Federal Republic of Germany, the situation of a national of a Member State who transfers his domicile from Germany to Switzerland is comparable to that of a national of a Member State who maintains his or her domicile in Germany. In both cases, the power to tax those capital gains falls to the Federal Republic of Germany, that power being linked, pursuant to its national legislation, to the domicile of the national concerned in its territory during the period when those capital gains accrued, irrespective of the place where they arose. |

| 61 | The question then arises whether the difference in treatment referred to in paragraphs 56 and 57 of the present judgment can be justified by the overriding reasons in the general interest described by the referring court and set out in paragraph 31 of the present judgment, namely the preservation of the allocation of powers of taxation between the parties to the AFMP concerned, the effectiveness of fiscal supervision and the need to guarantee the effective collection of the tax in order to prevent the loss of tax revenue. |

| 62 | In that regard, Article 21(3) of the AFMP provides that no provision of that agreement is to prevent the contracting parties from adopting or applying measures to ensure the imposition, payment and effective recovery of taxes or to forestall tax evasion under the national tax legislation of a contracting party or agreements aimed at preventing double taxation between Switzerland, of the one part, and one or more Member States, of the other part, or any other tax arrangements. |

| 63 | However, such measures, which correspond, according to the Court’s case-law in the context of free movement of persons within the European Union, to overriding reasons in the general interest (see, inter alia, judgments of 15 May 1997, Futura Participations and Singer, C‐250/95, EU:C:1997:239, paragraph 31 and the case-law cited; of 3 October 2006, FKP Scorpio Konzertproduktionen, C‐290/04, EU:C:2006:630, paragraph 36, and of 11 December 2014, Commission v Spain, C‐678/11, EU:C:2014:2434, paragraphs 45 and 46), must, in any event, have due regard for the principle of proportionality, that is, they must be appropriate for attaining those objectives and must not go beyond what is necessary in order to attain them. |

| 64 | In this case, it must be stated that, while the determination of the amount of tax at issue at the time of the transfer of domicile to Switzerland is a measure that is appropriate for attaining the objective relating to the preservation of the allocation of powers of taxation between that State and the Federal Republic of Germany, that objective cannot, however, justify it being impossible to defer payment of that tax. Such a deferral does not mean that the Federal Republic of Germany is surrendering, to the Swiss Confederation, its powers to tax the capital gains that have accrued during the period when the owner of the shares concerned had an unlimited liability to pay the German tax. |

| 65 | As regards the objective relating to the effectiveness of fiscal supervision, the Agreement between the Swiss Confederation and the Federal Republic of Germany makes provision for the possibility of an exchange of information on tax matters between the contracting parties, so that the Federal Republic of Germany could obtain from the competent Swiss authorities the information needed in relation to a disposal, by the national concerned who has earlier transferred his or her domicile to Switzerland, of the shares in which the unrealised capital gains at issue have arisen. Consequently, a denial of the possibility of deferring payment of the tax at issue in the main proceedings is a measure which, in any event, goes beyond what is necessary in order to achieve that objective. |

| 66 | As regards the objective relating to the need to guarantee the effective collection of the tax in order to prevent the loss of tax revenue, it is clear that the immediate collection of the tax at issue at the time when the taxpayer’s domicile is transferred may, as a general rule, be justified by the need to ensure the effective collection of tax liabilities. However, as the Advocate General stated in points 103 to 105 of his Opinion, that measure goes beyond what is necessary in order to achieve that objective and must therefore be considered to be disproportionate. In a situation where there is a risk of non-recovery of the tax payable, particularly where there is no mutual assistance mechanism for the recovery of tax debts, deferral of collection of that tax may be subject to an obligation to provide a guarantee (see, by analogy, judgments of 29 November 2011, National Grid Indus, C‐371/10, EU:C:2011:785, paragraphs 73 and 74, and of 23 January 2014, DMC, C‐164/12, EU:C:2014:20, paragraphs 65 to 67). |

In those circumstances, it must be concluded that the tax regime at issue in the main proceedings constitutes an unjustified restriction on the right of establishment provided for by the AFMP.

| 68 | That conclusion is not called into question by the fact that, in a situation where the immediate collection of the tax payable would have consequences that would be difficult for the taxpayer to bear, that tax regime provides for the possibility of payment of that tax in instalments. Leaving aside the fact that the instalment-payment measure is possible only in that specific situation, it is incapable of eliminating, in such a situation, the cash-flow disadvantage inherent in the obligation on the taxpayer to pay, at the time of the transfer of his domicile to Switzerland, a proportion of the tax payable on the unrealised capital gains with respect to the shares concerned. Moreover, that measure remains more onerous, for the taxpayer, than a measure that permits the deferral, until the disposal of those shares, of payment of the tax payable. |

| 69 | In the light of all the foregoing, the answer to the question referred is that the provisions of the AFMP must be interpreted as precluding a tax regime of a Member State which, in a situation where a natural person who is a national of a Member State and who pursues an economic activity in the territory of the Swiss Confederation transfers his domicile from the Member State whose tax regime is at issue to Switzerland, provides for the collection, at the time of that transfer, of the tax payable on unrealised capital gains with respect to shares owned by that national, whereas, if domicile is retained in that Member State, the collection of the tax takes place only at the time when the capital gains are realised, that is on a disposal of the shares concerned. |
