The DAC6 it introduces a reporting obligation on Intermediaries and Taxpayers, thereby obliging them, (in certain cases) to disclose potentially aggressive tax planning arrangements.
DAC 6 captures all kind of taxes with the exception of VAT, customs duties, excise duties and compulsory social contributions.
The DAC6 places an obligation on Intermediaries or Taxpayers to report to their respective national Tax Authority.

Intermediary are, inter alia, defined as:
any EU – established or resident person that designs, markets, organises or makes available the implementation of a reportable cross-border arrangement or
a person that based on the information in his possession and his relevant expertise and understanding required to provide such services, knows or could be reasonably expected to know that such persons have undertaken aid or advice with regards to the aforementioned services of a reportable cross-border arrangement.

In order to be an intermediary, a person shall meet at least one of the following additional conditions:
• be resident for tax purposes in a Member State
• have a Permanent Establishment (PE) on a Member state through which the services are provided
• Be incorporated in, or governed by the laws of a Member State
• Be registered with a professional association related to legal, taxation or consultancy services in a Member State.

It is to be noted that the above list is also relevant for cases were an intermediary has an obligation to report in more than one-member state and such a case the obliged intermediary shall make the stipulated disclosure in the country of residence.

Where the Intermediary is outside the scope of the EU or the corporate transaction was done in house, or the Intermediary is subject to professional confidentiality, the burden of direct reporting falls on the Taxpayer.

Exemptions to the Obligation to Report
An intermediary will be exempt from the reporting obligation in any other member state if:
• the reporting has been made in another member state
• reporting is subject to legal professional privilege.

What is a Reportable Cross-Border Arrangement:
It is a cross-border arrangement which has a characteristic or feature of a cross-border arrangement that presents an indication of a potential risk of tax avoidance.

A Cross Border Arrangement is defined as an arrangement concerning either more than one EU Member State, or a Member State and a third party/country and at least one of the following conditions are met:
• not all participants in the arrangement are tax resident in the same jurisdiction
• one or more of the participants is a dual tax resident
• one or more of the participants carries on a business in another jurisdiction through a permanent establishment
• one or more of the participants carries on a business in another jurisdiction without a permanent establishment
• the arrangement has a possible impact on the automatic exchange of information or the identification of the beneficial ownership.

Reportable Cross Border Transactions must have at least one of the designated Hallmarks: (the cross border arrangement must present an indication of a potential risk of tax avoidance) and must satisfy a Main Benefit Test (“MBT”), (this test means that one of the main objectives of the arrangement is to obtain a tax advantage.

Categories of Reportable Transactions
Category A: General hallmarks linked to the MBT
It includes:
• arrangements where the taxpayer or other involved parties, are requested to sign confidentiality agreements to avoid disclosing tax advantage
• arrangements that give rise to performance/success fees
• arrangements that involve mass-marketed schemes.

Category B: Specific hallmarks linked to the MBT
It includes the below tax planning arrangements:
• buying a loss-making company to exploit its losses in order to reduce tax liability.
• converting income into capital in order to obtain a tax benefit i.e. capitalization of a loan receivable given to a subsidiary company - instead of receiving income in the form of “interest income” that is taxable, the company will receive “dividend income” that is tax free or is taxed at a lower rate. Another example would be arrangements aimed at receiving back funds in a different form i.e. that provides tax advantage - instead of the company to pay dividend income to the s/h, the money can be returned via capital reduction.
• circular transactions resulting in the round-tripping of funds with no primary commercial function.

Category C: Specific hallmarks related to cross-border transactions; some of these hallmarks are also subject to the MBT:
• Category C1 applies to cases where there is a Deductible cross-border payment between associated persons and:
a. the recipient is not a tax resident in any jurisdiction
b. the recipient is a tax resident in one jurisdiction BUT:
(i) that jurisdiction has no tax, essentially zero or almost zero tax
(ii) the jurisdiction is included in a black-listed country

c. the payment is entitled to a full exemption from tax in the jurisdiction where the recipient is a tax resident
d. the payment benefits from a preferential tax regime in the jurisdiction where the recipient is a tax resident.

The arrangements covered by points b) (i), c) and d) are subject to the MBT.
• Category C2: deductions for depreciation on an asset claimed in more than one jurisdiction
• Category C3: double tax relief claimed in more than one jurisdiction in respect of the same income.
• Category C4: transfer of assets where the amount treated as payable is materially different between jurisdictions.

Category D: Specific hallmarks concerning the automatic exchange of information and beneficial ownership:
an arrangement is reportable if it has the effect of undermining the rules for automatic exchange of information (that under normal circumstances the information would have been exchanged) or the arrangement can provide protection from the disclosure of the Ultimate Beneficial Owner.

Category E: Specific hallmarks concerning transfer pricing:
It includes the following:
• use of unilateral safe harbours
• the transfer of hard-to-value intangible assets where the projection of future cash flows or income are highly uncertain
• cross-border transfer of functions/risks/assets causing a more than 50% decrease (using projections) in Earnings Before Interest and Tax (EBIT) during the next 3 years.
