Mandatory Disclosure Regime (MDR)

Countries are implementing mandatory disclosure rules aimed at increasing transparency to detect what is perceived by tax authorities to be potentially aggressive cross-border tax planning. We can work with you to identify and help manage cross-border reporting obligations by leveraging our global network and up-to-date tools.

What EY can do for you

MDR will lead to extensive reporting obligations for a relatively wide range of transactions being classified as reportable arrangements. No jurisdiction other than Mexico has introduced any de minimis rules. Taxpayers and intermediaries (e.g. advisors, banks etc.) must implement policies, procedures and processes to identify and capture details of transactions that they may need to disclose. Penalties can be significant.

EY teams across the world can help taxpayers and intermediaries (e.g., advisors, banks etc.) identify and manage their obligations under the MDR. 

Do you have a process to manage your MDR obligations?

  • EY teams can assist in the development of process guidelines and/or policies for MDR reporting, from the day-to-day identification of reportable arrangements up to the data submission to the tax authorities.

Why is this relevant?

  • There may be situations where you may have a reporting obligation. Penalties for incomplete or late filing can be significant.

Have you appointed a person as the process owner for MDR compliance and are the responsibilities for MDR reporting defined within your organization? Why is this relevant?

  • The responsibility for MDR compliance often starts with the Tax function. However, the responsibility for adequate processes, up-to-date MDR knowledge and timely filing may be with different parts of your organization.

Have you conducted an MDR impact assessment? If so, what was the outcome for the countries where you have a footprint?

  • It is important to identify and assess the potentially reportable transactions based on the regulations applicable. Even though EU MDR rules are based on DAC 6, there are differences in how this has been transposed and implemented across the EU member states. Argentina and Mexico each have their own set of reportable hallmarks under their own MDR.

Why is this relevant?

  • MDR may impact your internal and external processes a lot, depending on your EU footprint, legal structure and your business activities. Documenting where and to what extent MDR may impact your organization is important.

Other stakeholders may request this information (e.g., internal audit, external auditors, tax authorities, etc).

Do you have a process to understand what has been reported by your intermediaries (e.g. advisors, banks etc.)?

  • Generally, the reporting obligation lies with intermediaries. Intermediaries may only have limited information on the broader background and relevant taxpayers have to deal with any follow up questions raised by the tax authorities.

Why is this relevant?

  • In certain EU jurisdictions, you may have to annually report which MDR disclosures have been made.

Do you have a process to meet the 30-day deadline in the EU, Mexico and the UK or 10- day deadline in Argentina?

  • A delayed reporting can trigger penalties that can amount for MDR reporting failures of up to e.g. Euro 5m in the EU.

Why is this relevant?

  • The rolling 30-day deadline in practice is very short. This may make relying on your existing compliance processes risky, especially where they do not operate frequently or seamlessly enough to ensure compliance with the tight deadlines.

EY teams can assist you with the reporting of your arrangements in the format as requested by the local tax authorities.
