VinciWorks understands that the UK is unlikely to introduce its own version of the Mandatory Disclosure Rules (UK MDR) before 2023.

As the government has changed and the Treasury has fully changed its Ministers, including the Financial Secretary to the Treasury who is responsible for tax policies, the official position is that the government is still reviewing the consultation responses. It is unlikely that we can expect any serious developments in relation to UK MDR in the near future.

VinciWorks is in regular discussion with HMRC and will be providing updates when we have more information.

Companies being investigated for failure to prevent facilitation of tax evasion 

The Criminal Finances Act, which came into force in September 2017, introduced the requirement for businesses to have reasonable procedures to prevent the facilitation of tax evasion. If you do not feel that your organisation complies with the Criminal Finances Act, it is important to start a thorough risk assessment of all areas of your business operations. Organisations must also draw up an implementation plan that includes training on the Criminal Finances Act.

The UK government periodically announces investigations being undertaken under the Corporate Criminal Offences (CCO).

UK MDR is making small steps towards implementation. The IT and Policy teams at HMRC are hard at work finalising everything that is required ahead of the new legislation.

Between November 2021 and February 2022, HMRC conducted a consultation on the new UK MDR legislation. While the results of the consultation have not yet been published, we understand that the results are ready and HMRC are making good progress with the final legislation. The announcement of a start date for UK MDR is expected soon.

On 11 January 2022, the UK government published a consultation seeking views for how a worldwide 15% minimum corporation tax should be domestically implemented. The consultation will run for 12 weeks, until 4 April 2022.


In May 2019, the OECD/G20 Inclusive Framework on BEPS (Inclusive Framework) agreed a Programme of Work for Addressing the Tax Challenges of the Digitalisation of the Economy. 

The Programme of Work is divided into two pillars:

Pillar One addresses the allocation of taxing rights between jurisdictions and considers various proposals for new profit allocation and nexus rules;

Pillar Two (also referred to as the “GloBE” proposal) focuses on the remaining BEPS issues and seeks to develop rules that would provide jurisdictions with a right to “tax back” where other jurisdictions have not exercised their primary taxing rights or the payment is otherwise subject to low levels of effective taxation.

What is the history of the EU’s list of non-cooperative jurisdictions?

In January 2016, the EU Commission presented its Anti-Tax Avoidance Package, in which it committed to a  “clear, coherent and objective” approach to tackle tax governance in relation to non-EU jurisdictions. 

In November 2016, the Council mandated the Code of Conduct group (business taxation), a Council working party, to carry out the preparatory work to establish a list of non-cooperative jurisdictions.

The Code of Conduct group screened 92 jurisdictions, selected on the basis of:

  1. their economic ties with the EU
  2. their institutional stability
  3. the importance of the country’s financial sector

In December 2017 the EU launched its initial list of non-cooperative jurisdictions for tax purposes. The list included non-EU countries that encourage abusive tax practices, which erode member states’ corporate tax revenues.

The EU list of non-cooperative jurisdictions for tax purposes is a tool to tackle:

  1. tax fraud or evasion: illegal non-payment or underpayment of tax
  2. tax avoidance: use of legal means to minimise tax liability
  3. money laundering: concealment of origins of illegally obtained money

The first list included 17 non-EU countries or territories. A state of play document was also released that set out the jurisdictions which had responded with sufficient commitments. They needed to take effective action by the end of 2018, or in some cases 2019, to avoid being listed in the future.

On 30 November 2021, HMRC published its draft UK Mandatory Disclosure Rules (MDR) and released its consultation which seeks views on the design of the draft regulations. The consultation will be open until 8 February 2022. The UK MDR is expected to come into force in summer 2022, replacing UK DAC6.

MDR requires advisers (and sometimes taxpayers) to report information to the tax authorities on certain prescribed arrangements and structures, including those that could circumvent existing tax transparency reporting rules known as the Common Reporting Standard or hide ownership of assets.

For this webinar, we were joined by John Sandeman, HMRC’s policy official for Mandatory Disclosure Rules, who helped attendees get to grips with the UK MDR and how it applies to your organisation. John also answered attendee questions.

The webinar covered:

  • Who does UK MDR apply to?
  • Top challenges firms are facing
  • Best practice for submitting reports under MDR
  • Approaches to legal professional privilege
  • What guidance HMRC are planning to release

In 2018 the OECD developed Model Mandatory Disclosure Rules for CRS Avoidance Arrangements and Opaque Offshore Structures (“OECD’s Model Rules”). These rules require taxpayers and their advisers to report information to tax authorities on certain types of arrangements and structures that might facilitate tax evasion.

The EU responded to the OECD’s mandatory disclosure rules by introducing the EU Council Directive 2011/16, more commonly known as DAC6. As of January 2021, reporting under DAC6 was mandatory in all EU Member States.

Prior to the UK’s exit from the European Union, the UK government intended to adhere to the DAC6 regulations in line with the other EU member States. But at the spring Budget 2021, the UK government announced that DAC6 would be replaced with model rules in line with the OECD’s Model Rules. The consultation released on 30 November 2021 relates to the draft regulations to implement UK MDR, which means that the rules will apply on a global, rather than an EU, level following Brexit.

What is the UK MDR?

UK MDR refers to the UK’s Mandatory Disclosure Rules, the new regulations that came into force in summer 2022 and replace the current UK DAC6 regulations. The regulations are aimed at preventing tax evasion by requiring taxpayers and intermediaries to disclose information on certain types of arrangements and structures to HMRC. The UK MDR limited the regulations as they existed under DAC6 to apply to only those arrangements that would be reportable under the OECD’s Model Rules.

New Changes in UK MDR: Free Guide

VinciWorks has developed a guide to UK MDR that goes through everything you need to know on the subject. The topics covered in the overview include an overview of the UK’s approach, how UK MDR will be different from DAC6, timelines for implementation, and what will happen to the existing DAC6 regulations in the UK. The guide then goes on to cover information about historic reporting periods, intermediaries, taxpayers, hallmarks, reporting obligations, penalties, and reporting format. Finally, the guide introduces VinciWorks’ own DAC6 and MDR reporting solution.

HMRC MDR consultation

On 30 November 2021, HMRC published their draft UK Mandatory Disclosure Rules and released their consultation which seeks views on the design of the draft regulations. The consultation will be open until 8 February 2022.

At the Spring Budget 2021, the UK Government announced that it would implement Mandatory Disclosure Rules(MDR)(2.14). The rules are intended to replace the similar EU DAC6 rules which were implemented in the UK prior to their exit from the European Union. The draft regulations draw closely to the OECD’s Model Mandatory Disclosure Rules for CRS Avoidance Arrangements and Opaque Offshore Structures.

MDR requires advisers (and sometimes taxpayers) to report information to the tax authorities on certain prescribed arrangements and structures including those that could circumvent existing tax transparency reporting rules known as the Common Reporting Standard or hide ownership of assets. 

VinciWorks will be hosting a webinar in the coming weeks with representatives from HMRC to discuss the consultation.

DAC6 legislation in Malta requires that an intermediary who is exempt from reporting in Malta (such as those who rely on legal professional privilege) must provide the Commissioner for Revenue with an annual updated situation including a list of the reportable cross-border arrangements that were not reported.

On 11 November 2021, the Maltese Commissioner for Revenue announced that the deadline for the notification needs to be submitted by 28 February 2022 for all transactions where the triggering event was met by 31st December 2021.

The annual notification form can be accessed here.
