The application of tax treaties to fiscally transparent entities is controversial. Two requirements for the application of the benefits of a tax treaty (that is, the elimination or reduction of the source country tax on payments made by a person resident in one Contracting State, to a person resident in the other Contracting Sate) are that the person receiving the payment is a "resident" of the other contracting state, and the "beneficial owner" of the payment.
Residence is usually defined in tax treaties (typically, under article 4, paragraph 1), as requiring that a person be "liable to tax" in the other Contracting States, by reason of his residence, domicile, place of management, place of incorporation or other criterion of a similar nature (article 4, paragraph 1).
According to the OECD, whenever an entity is treated as fiscally transparent in a State, the entity is not "liable to tax" in that State, within the meaning of article 4, paragraph 1, and so it cannot be a resident thereof for purposes of a treaty. In such case, the entity’s partners or owners should be entitled to the benefits of the treaty entered into by the State of which they are residents, with respect to their share of the income of the entity, to the extent that the entity’s income is allocated to them under the tax laws of their State of residence (see OECD Commentary to the Model Tax Convention, on Article 1, paragraph 5).
The current Tax Treaty between Italy and the United States adopts a slightly different approach and assigns tax residency to a an entity that is treated as fiscally transparent entity in the United States, for the purposes of the treaty, to the extent that the entity’s income is taxed in the U.S in the hands of its parents or beneficiaries. In fact, in the case of income derived or paid by a partnership, estate of trust, this term applies only to the extent that the income derived by such partnership, estate or trust is subject to tax in that State, either in its hands or in . Article 1, paragraph 5, letter d) of the Protocol extends the same provision to fiscally transparent entities, by providing that The provisions of subparagraph 1(b) of Article 4 (Resident) of the
As for the second requirement, the term "beneficial owner" is generally not defined in tax treaties. However, the 2014 Update to the OECD Model Tax Convention issued by OECD the Committee on Fiscal Affairs on June 26, 2014 clarifies the meaning of beneficial owner as requiring that a person have "the right to use and enjoy" the income, "unconstrained by a contractual or legal obligation to pass on the payment received to another person". Sometimes, the term is interpreted as meaning that the beneficial owner is the person to whom the income is attributed for tax purposes under the tax laws of a Contracting State.
The EU Directive 2003/49/EC of June 3, 2003 provides a definition of the term “beneficial owner” for the purposes of the withholding tax exemption of interest and royalties paid to a EU parent or affiliate corporation, according to which “A company of a Member State shall be treated as the “beneficial owner” of interest or royalties only if it receives those payments for its own benefit and not as an intermediary, such as an agent, trustee or authorized signatory, for some other person”. Circular 47/E of November 2, 2005, which at paragraph 2.3.2 clarifies that in order for a company to be considered the beneficial owner of the interest or royalties, “it is necessary that the company receives the payment as the ultimate beneficiary, not as an intermediary such as an agent, a fiduciary, or collector of the payment for another person, … and that the company receiving the interest or royalties derives a direct personal economic benefit from the income from the transaction”.
Clearly, the tax treatment of an entity in its country of organization is key to determine whether the entity, or its shareholders, partners or members, are entitled to the benefits of a treaty with respect to a parent made by a resident of the other Contracting State. The residence and beneficial owner requirements, whose meaning is not entirely free from doubt, and depends on the facts and circumstances of the particular case, call for extensive analysis of the tax classification and treatment of the entity and its owners, under the laws of their country or organization or asserted residence, as well as the organizational structure, role and functions of the entity receiving the payment. Under that scenario, the payer of the income bearing withholding agent obligations is usually under pressure, and must make sure that the documentation provided by the payee establishes with sufficient certainty the payee’s eligibility for treaty benefit.
