Convention on Mutual Administrative Assistance in Tax Matters

Strasbourg, 25.I.1988

Preamble

    The member States of the Council of Europe and the member countries of the Organisation for Economic Co-operation and Development (OECD), signatories of this Convention,
    Considering that the development of international movement of persons, capital, goods and services – although highly beneficial in itself – has increased the possibilities of tax avoidance and eva-sion and therefore requires increasing co-operation among tax authorities;
    Welcoming the various efforts made in recent years to combat tax avoidance and tax evasion on an international level, whether bilaterally or multilaterally;
    Considering that a co-ordinated effort between States is necessary in order to foster all forms of administrative assistance in matters concerning taxes of any kind whilst at the same time ensuring adequate protection of the rights of taxpayers;
    Recognising that international co-operation can play an important part in facilitating the proper determination of tax liabilities and in helping the taxpayer to secure his rights;
    Considering that fundamental principles entitling every person to have his rights and obligations determined in accordance with a proper legal procedure should be recognised as applying to tax matters in all States and that States should endeavour to protect the legitimate interests of taxpayers, including appropriate protection against discrimination and double taxation;
    Convinced therefore that States should not carry out measures or supply information except in conformity with their domestic law and practice, having regard to the necessity of protecting the confidentiality of information, and taking account of international instruments for the protection of privacy and flows of personal data;
    Desiring to conclude a convention on mutual administrative assistance in tax matters,
    Have agreed as follows:

Chapter I – Scope of the Convention

    2. assistance in recovery, including measures of conservancy; and
    3. service of documents.
  3. A Party shall provide administrative assistance whether the person affected is a resident or national of a Party or of any other State.

      2. taxes on capital gains which are imposed separately from the tax on income or profits;

      2. compulsory social security contributions payable to general government or to social security institutions established under public law;

Such change shall take effect on the first day of the month following the expiration of a period of three months after the date of receipt of such notification by the Depositary.
  4. The Convention shall also apply, as from their adoption, to any identical or substantially similar taxes which are imposed in a Contracting State after the entry into force of the Convention in respect of that Party in addition to or in place of the existing taxes listed in Annex A and, in that event, the Party concerned shall notify one of the Depositaries of the adoption of the tax in question.

Chapter III – Forms of assistance

  1. The Parties shall exchange any information, in particular as provided in this section, that is foreseeably relevant to:
    1. the assessment and collection of tax, and the recovery and enforcement of tax claims, and
    2. the prosecution before an administrative authority or the initiation of prosecution before a judicial body.
    Information which is unlikely to be relevant to these purposes shall not be exchanged under this Convention.
  2. A Party may use information obtained under this Convention as evidence before a criminal court only if prior authorisation has been given by the Party which has supplied the information. However, any two or more Parties may mutually agree to waive the condition of prior authorisation.
  3. Any Party may, by a declaration addressed to one of the Depositories, indicate that, according to its internal legislation, its authorities may inform its resident or national before transmitting information concerning him, in conformity with Articles 5 and 7.
  1. At the request of the applicant State, the requested State shall provide the applicant State with any information referred to in Article 4 which concerns particular persons or transactions.
  2. If the information available in the tax files of the requested State is not sufficient to enable it to comply with the request for information, that State shall take all relevant measures to provide the applicant State with the information requested.
    With respect to categories of cases and in accordance with procedures which they shall determine by mutual agreement, two or more Parties shall automatically exchange the information referred to in Article 4.
  1. A Party shall, without prior request, forward to another Party information of which it has knowledge in the following circumstances:
    1. the first-mentioned Party has grounds for supposing that there may be a loss of tax in the other Party;
    2. a person liable to tax obtains a reduction in or an exemption from tax in the first-mentioned Party which would give rise to an increase in tax or to liability to tax in the other Party;
    3. business dealings between a person liable to tax in a Party and a person liable to tax in another Party are conducted through one or more countries in such a way that a saving in tax may result in one or the other Party or in both;
    4. a Party has grounds for supposing that a saving of tax may result from artificial transfers of profits within groups of enterprises;
    5. information forwarded to the first-mentioned Party by the other Party has enabled information to be obtained which may be relevant in assessing liability to tax in the latter Party.
  2. Each Party shall take such measures and implement such procedures as are necessary to ensure that information described in paragraph 1 will be made available for transmission to another Party.
  1. At the request of one of them, two or more Parties shall consult together for the purposes of determining cases and procedures for simultaneous tax examinations. Each Party involved shall decide whether or not it wishes to participate in a particular simultaneous tax examination.
  2. For the purposes of this Convention, a simultaneous tax examination means an arrangement between two or more Parties to examine simultaneously, each in its own territory, the tax affairs of a person or persons in which they have a common or related interest, with a view to exchanging any relevant information which they so obtain.
  1. At the request of the competent authority of the applicant State, the competent authority of the requested State may allow representatives of the competent authority of the applicant State to be present at the appropriate part of a tax examination in the requested State.
  2. If the request is acceded to, the competent authority of the requested State shall, as soon as possible, notify the competent authority of the applicant State about the time and place of the examination, the authority or official designated to carry out the examination and the procedures and conditions required by the requested State for the conduct of the examination. All decisions with respect to the conduct of the tax examination shall be made by the requested State.
  3. A Party may inform one of the Depositaries of its intention not to accept, as a general rule, such requests as are referred to in paragraph 1. Such a declaration may be made or withdrawn at any time.
    If a Party receives from another Party information about a person's tax affairs which appears to it to conflict with information in its possession, it shall so advise the Party which has provided the information.
  1. At the request of the applicant State the requested State shall, subject to the provisions of Articles 14 and 15, take the necessary steps to recover tax claims of the first-mentioned State as if they were its own tax claims.
  2. The provision of paragraph 1 shall apply only to tax claims which form the subject of an instrument permitting their enforcement in the applicant State and, unless otherwise agreed between the Parties concerned, which are not contested. However, where the claim is against a person who is not a resident of the applicant State, paragraph 1 shall only apply, unless otherwise agreed between the Parties concerned, where the claim may no longer be contested.
  3. The obligation to provide assistance in the recovery of tax claims concerning a deceased person or his estate, is limited to the value of the estate or of the property acquired by each beneficiary of the estate, according to whether the claim is to be recovered from the estate or from the beneficiaries thereof.
    At the request of the applicant State the requested State shall, with a view to the recovery of an amount of tax, take measures of conservancy even if the claim is contested or is not yet the subject of an instrument permitting enforcement.
  1. The request for administrative assistance under this section shall be accompanied by:
    1. a declaration that the tax claim concerns a tax covered by the Convention and, in the case of recovery that, subject to paragraph 2 of Article 11, the tax claim is not or may not be contested;
    2. an official copy of the instrument permitting enforcement in the applicant State; and
    3. any other document required for recovery or measures of conservancy.
  2. The instrument permitting enforcement in the applicant State shall, where appropriate and in accordance with the provisions in force in the requested State, be accepted, recognised, supplemented or replaced as soon as possible after the date of the receipt of the request for assistance, by an instrument permitting enforcement in the latter State.
  1. Questions concerning any period beyond which a tax claim cannot be enforced shall be governed by the law of the applicant State. The request for assistance shall give particulars concerning that period.
  2. Acts of recovery carried out by the requested State in pursuance of a request for assistance, which, according to the laws of that State, would have the effect of suspending or interrupting the period mentioned in paragraph 1, shall also have this effect under the laws of the applicant State. The requested State shall inform the applicant State about such acts.
  3. In any case the requested State is not obliged to comply with a request for assistance which is submitted after a period of 15 years from the date of the original instrument permitting enforcement.
    The tax claim in the recovery of which assistance is provided shall not have in the requested State any priority specially accorded to the tax claims of that State even if the recovery procedure used is the one applicable to its own tax claims.
    The requested State may allow deferral of payment or payment by instalments if its laws or administrative practice permit it to do so in similar circumstances but shall first inform the applicant State.
  1. At the request of the applicant State the requested State shall serve upon the addressee documents, including those relating to judicial decisions, which emanate from the applicant State and which relate to a tax covered by this Convention.
  2. The requested State shall effect service of documents:
    1. by a method prescribed by its domestic laws for the service of documents of a substantially similar nature;
    2. to the extent possible, by a particular method requested by the applicant State or the closest to such method available under its own laws.
  3. A Party may effect service of documents directly through the post on a person within the territory of another Party.
  4. Nothing in the Convention shall be construed as invalidating any service of documents by a Party in accordance with its laws.
  5. When a document is served in accordance with this article it need not be accompanied by a translation. However, where it is satisfied that the addressee cannot understand the language of the document the requested State shall arrange to have it translated into or a summary drafted in its or one of its official languages. Alternatively, it may ask the applicant State to have the document either translated into or accompanied by a summary in one of the official languages of the requested State, the Council of Europe or OECD.

Chapter IV – Provisions relating to all forms of assistance

  1. A request for assistance shall indicate where appropriate:
    1. the authority or agency which initiated the request made by the competent authority;
    2. the name, address and any other particulars assisting in the identification of the person in respect of whom the request is made;
    3. in the case of a request for information, the form in which the applicant State wishes the information to be supplied in order to meet its needs;
    4. in the case of a request for assistance in recovery or measures of conservancy, the nature of the tax claim, the components of the tax claim and the assets from which the tax claim may be recovered;
    5. in the case of a request for service of documents, the nature and the subject of the document to be served;
    6. whether it is in conformity with the law and administrative practice of the applicant State and whether it is justified in the light of the requirements of Article 19.
  2. As soon as any other information relevant to the request for assistance comes to its knowledge, the applicant State shall forward it to the requested State.
    The requested State shall not be obliged to accede to a request if the applicant State has not pursued all means available in its own territory, except where recourse to such means would give rise to disproportionate difficulty.
  1. If the request for assistance is complied with, the requested State shall inform the applicant State of the action taken and of the result of the assistance as soon as possible.
  2. If the request is declined, the requested State shall inform the applicant State of that decision and the reason for it as soon as possible.
  3. If, with respect to a request for information, the applicant State has specified the form in which it wishes the information to be supplied and the requested State is in a position to do so, the requested State shall supply it in the form requested.
  1. Nothing in this Convention shall affect the rights and safeguards secured to persons by the laws or administrative practice of the requested State.
  2. Except in the case of Article 14 the provisions of this Convention shall not be construed so as to impose on the requested State the obligation:
    1. to carry out measures at variance with its own laws or administrative practice or the laws or administrative practice of the applicant State;
    2. to carry out measures which it considers contrary to public policy (ordre public) or to its essential interests;
    3. to supply information which is not obtainable under its own laws or its administrative practice or under the laws of the applicant State or its administrative practice;
    4. to supply information which would disclose any trade, business, industrial, commercial or professional secret, or trade process, or information the disclosure of which would be contrary to public policy (ordre public) or to its essential interests;
    5. to provide administrative assistance if and insofar as it considers the taxation in the applicant State to be contrary to generally accepted taxation principles or to the provisions of a convention for the avoidance of double taxation, or of any other convention which the requested State has concluded with the applicant State;
    6. to provide assistance if the application of this Convention would lead to discrimination between a national of the requested State and nationals of the applicant State in the same circumstances.
  1. Any information obtained by a Party under this Convention shall be treated as secret in the same manner as information obtained under the domestic laws of that Party, or under the conditions of secrecy applying in the supplying Party if such conditions are more restrictive.
  2. Such information shall in any case be disclosed only to persons or authorities (including courts and administrative or supervisory bodies) involved in the assessment, collection or recovery of, the enforcement or prosecution in respect of, or the determination of appeals in relation to, taxes of that Party. Only the persons or authorities mentioned above may use the information and then only for such purposes. They may, notwithstanding the provisions of paragraph 1, disclose it in public court proceedings or in judicial decisions relating to such taxes, subject to prior authorisation by the competent authority of the supplying Party. However, any two or more Parties may mutually agree to waive the condition of prior authorisation.
  3. If a Party has made a reservation provided for in sub-paragraph a of paragraph 1 of Article 30, any other Party obtaining information from that Party shall not use it for the purpose of a tax in a category subject to the reservation. Similarly the Party making such a reservation shall not use information obtained under this Convention for the purpose of a tax in a category subject to the reservation.
  4. Notwithstanding the provisions of paragraphs 1, 2 and 3, information received by a Party may be used for other purposes when such information may be used for such other purposes under the laws of the supplying Party and the competent authority of that Party authorises such use. Information provided by a Party to another Party may be transmitted by the latter to a third Party, subject to prior authorisation by the competent authority of the first-mentioned Party.
  1. Proceedings relating to measures taken under this Convention by the requested State shall be brought only before the appropriate body of that State.
  2. Proceedings relating to measures taken under this Convention by the applicant State, in particular those which, in the field of recovery, concern the existence or the amount of the tax claim or the instrument permitting its enforcement, shall be brought only before the appropriate body of that State. If such proceedings are brought, the applicant State shall inform the requested State which shall suspend the procedure pending the decision of the body in question.

    3. However, the requested State shall, if asked by the applicant State, take measures of conservancy to safeguard recovery. The requested State can also be informed of such proceedings by any interested person. Upon receipt of such information the requested State shall consult on the matter, if necessary, with the applicant State.
  3. As soon as a final decision in the proceedings has been given, the requested State or the applicant State, as the case may be, shall notify the other State of the decision and the implications which it has for the request for assistance.
