DAC 6: UK implementation of the new EU tax disclosure rules

Consultation and draft regulations for the mandatory reporting of cross-border transactions for taxpayers and intermediaries

Publication August 2019


DAC 6 imposes mandatory reporting of cross-border arrangements affecting at least one EU member state where the arrangements fall within one of a number of “hallmarks”. The use of broad categories designed to encompass particular characteristics viewed as indicative of aggressive tax planning follows the approach taken by the UK in implementing its DOTAS regime back in 2004. The hallmarks under DAC 6 are much broader, however, and more parties are likely to find themselves being classed as “intermediaries”, on whom the reporting obligation falls, than is the case with those classed as “promoter” under the DOTAS regime. The potential application of DAC 6 to standard transactions with no particular tax motive is likely to create a compliance burden that is going to be difficult to comply with.

This has been compounded by the implementation timeline, which provided for implementation with retrospective effect, meaning that the disclosure obligations were “live” from June 25, 2018, before any implementing legislation or guidance had been published.

This has meant that intermediaries have had to monitor arrangements from June 25 last year without any real clarity as to what will be reportable or, indeed, if they are an intermediary at all. The cross-border implementation of the regime adds to the compliance burden as the position may need reviewing in more than one EU jurisdiction to ensure the domestic rules are aligned, which seems contrary to the aim of having an EU-wide reporting regime.

The headlines

  • The regulations cross-refer to the Directive for key concepts (such as the description of the hallmarks) and definitions of key terms (intermediaries, relevant taxpayer, reportable cross-border arrangement, and reportable information). The consultation document provides some commentary on how HMRC interpret the Directive but there are a number of areas where greater clarity is needed. Guidance is promised, to be published before implementation of the regime at end of 2019.
  • HMRC split intermediaries into “promoters” (similar to DOTAS concept) and “service providers. There is some reassuring commentary on what will be deemed to be in the knowledge of an intermediary acting as a service provider.
  • HMRC’s interpretation potentially limits the extent of UK disclosure in areas including standardised products and double depreciation. If other jurisdictions take a different approach this may not limit reporting requirements in practice.
  • There is some clarification of the “main benefit test. The test is to be applied objectively, looking at the benefits a person might reasonably be expected to obtain, rather than actual motives and objectives. There will be no tax advantage if the consequences of the arrangement are in line with the policy intent of the legislation the arrangement relies on. On this basis, HMRC view products such as ISAs and pensions as not caught unless by reason of being part of a wider arrangement.
  • Reporting will be electronic and HMRC will allocate an arrangement reference number to the reported arrangement. HMRC expects there to be a standard template for reporting. Relevant taxpayers will then have to make an annual report for each period that they participate in the arrangement. The detail has not yet been decided, but it is anticipated that this would be made in income or corporation tax returns.
  • Penalties for failure to report the cross-border arrangement largely follow the DOTAS approach (starting with daily penalties of up to £600 but allowing for the First-tier Tribunal to impose penalties of up to £1m). Failure by a relevant taxpayer to make an annual return can be up to £10,000 per arrangement. Due to retrospectivity the regime has, effectively been live since July 25, 2018. HMRC will make some allowances for the period up to publication of the consultation where failure to comply was due to a lack of clarity around the rules.

How far does the consultation take us?

It has been clear, since the publication of the Directive in June last year, that the DAC 6 reporting obligations would be far-reaching and that they would impose a significant compliance burden. What is becoming evident now that domestic implementation is starting is just how problematic the cross-border nature of the regime is and that it may give rise to surprising results.

On July 22, 2019, HMRC published draft implementing regulations and a consultation document. The regulations stick closely to the Directive itself, cross-referencing directly to definitions and the underlying operative provisions of the Directive in many places. It is the consultation that provides some insight on HMRC’s view. It also asks for comment and input on a number of areas with a deadline for responses of October 11, 2019. The use of examples to illustrate HMRC’s position is limited. HMRC’s fuller guidance, promised before implementation at the end of 2019 will hopefully provide more.

It is clear from the consultation that, in a number of areas where concerns had been raised, such as the reporting of standardised products, or double depreciation of an asset, HMRC are proposing to adopt an interpretation which limits the potential extent of disclosure. HMRC have also provided reassuring comments in relation to the extent of an intermediary’s deemed knowledge of the arrangements.

Unless the various domestic regimes are aligned, however, this will not affect whether disclosure is required in another member state. UK-resident intermediaries may well find themselves in a situation where the fact that there is no reporting requirement in the UK means that they need to consider the rules in a number of other relevant jurisdictions and make reports in jurisdictions with which they have more limited involvement, adding a significant compliance burden.

Where a report needs to be made and exactly what needs to be reported is far from straightforward. A London branch of an international bank headquartered in another member state is likely to need to report London-arranged transactions in its head office jurisdiction, rather than in the UK. If the arrangement is not reportable in that jurisdiction because of the way that jurisdiction has implemented the Directive, the bank may need to consider the position in the branch location. Even if the arrangement is reportable in the head office jurisdiction, that is not the end of the story: the bank may still need to consider whether the report made includes all information potentially reportable under the UK rules.

The London branch may also be surprised to hear that HMRC do not consider the fact that an arrangement is compliant with the banking code of practice as meaning that it is outside DAC 6. It is a far from straightforward regime to comply with.

The UK consultation: who is an intermediary?

Intermediaries have the primary obligation to report. The draft regulations define “intermediary” by reference to the Directive. It includes anyone who designs, markets, organises or makes available or implements a reportable arrangement or anyone who helps with reportable activities and knows or could reasonably be expected to know that they are doing so. The consultation provides some clarification, identifying two “types” of intermediary.

The first, “promoters”, actually design, market, organise or make available or implement a reportable arrangement. The second, “service providers”, merely provide assistance or advice in relation to those activities.

The key distinction is that a service provider will not be an intermediary if they did not know and could not reasonably have been expected to know that they were involved in a reportable arrangement. This provides an important safety net for service providers involved at the periphery of a transaction. The example given is of a bank providing finance. This is a welcome clarification: the bank is not expected to make a disclosure if it does not have sufficient knowledge of the wider arrangements and, crucially, whether any hallmark is triggered.

Another welcome clarification is that service providers are not expected to do significant extra due diligence to establish whether an arrangement is reportable. The bank, in this example, should do the “normal” due diligence it would do for the client and transaction in question. Of course, remaining wilfully ignorant will leave the bank on the wrong side of the “could reasonably be expected to know” test.

Promoters are assumed to understand how the arrangement works so there is no similar exclusion available to them.

When is there a tax advantage “main benefit”?

A number of the hallmarks only apply if a threshold “main benefit” test is met (see the table below). This is met where one of the main benefits that a person might reasonably expect to derive from an arrangement is a “tax advantage”. The consultation is clear that HMRC view this as an objective test: what matters is whether a tax advantage is the main or one of the main benefits that the person entering into the arrangement might reasonably be expected to obtain from the arrangement. That person’s actual motivation in entering into the arrangement is not relevant. This “main benefit” concept is used in other UK regimes and is notoriously difficult to apply. The UK guidance in respect of a similar test under DOTAS views “main benefit” as picking up any benefit that is not “incidental”, a low threshold.

The key to applying this threshold test lies in HMRC’s interpretation of “tax advantage” and it’s here that the consultation provides some helpful commentary, in particular noting that the there be no “tax advantage” if the tax consequences of the arrangement are in line with the policy intent of the legislation upon which the arrangement relies. On this basis, HMRC view products such as ISAs and pensions, designed and intended to generate a certain beneficial tax outcome, as not meeting the test unless by reason of being part of a wider arrangement.

“Tax advantage” is defined in the regulations as including

  • Relief or increased relief from tax
  • Repayment or increased repayment of tax
  • Avoidance or reduction of a charge to tax or an assessment to tax
  • Deferral of a payment of tax or advancement of a repayment of tax
  • Avoidance of an obligation to withhold or account for tax.

“Tax” for these purposes means any tax to which the Directive applies (i.e. taxes levied by member states excluding VAT, customs duties, excise duties and compulsory social security contributions) and any equivalent taxes worldwide. The inclusion of worldwide taxes is not a surprise: HMRC were clear early on that they saw the EU nexus as contained in the definition of “cross-border arrangement” and that arrangements that avoid tax in a jurisdiction outside the EU but that involve a member state should nevertheless be disclosable.

The hallmarks

This table summarises the hallmarks and, importantly, distinguishes those to which the “main benefit” threshold applies.

Categories Hallmarks “main benefit” test? 
Category A

Commercial characteristics seen in marketed tax avoidance schemes
Taxpayer or participant under a confidentiality condition in respect of how the arrangements secure a tax advantage.  
Intermediary paid by reference to the amount of tax saved or whether the scheme is effective  
Standardised documentation and/or structure.  

 Category B

Tax structured arrangements seen in avoidance planning
Converting income into capital.  
Circular transactions resulting in the round-tripping of funds with no other primary commercial function.  

Category C

Cross-border payments, transfers broadly drafted to capture innovative planning but which may pick up many ordinary commercial transactions where there is no main tax benefit.
Deductible cross-border payment between associated persons…   
  to a recipient not resident for tax purposes in any jurisdiction.  
to recipient resident in a 0 per cent or near 0 per cent tax jurisdiction.  
to recipient resident in a blacklisted countries.  
which is tax exempt in the recipient’s jurisdiction.  
which benefits from a preferential tax regime in the recipient jurisdiction  
Deductions for depreciation claimed in more than one jurisdiction.  
Double tax relief claimed in more than one jurisdiction in respect of the same income.  
Asset transfer where amount treated as payable is materially different between jurisdictions.  

Category D

Arrangements which undermine tax reporting under the CRS/transparency.
Arrangements which have the effect of undermining reporting requirements under agreements for the automatic exchange of information.

Arrangements which obscure beneficial ownership and involve the use of offshore entities and structures with no real substance.  
Arrangements involving the use of unilateral transfer pricing safe harbour rules.

Cross-border transfer of functions/risks/assets projected to result in a more than 50 per cent decrease in EBIT during the next three years.  

Key points from the consultation

The consultation comments on each category of hallmark.

Category A: the “generic hallmarks”

The “generic hallmarks” (confidentiality, fees based on tax advantage obtained, use of standardised documentation) are all subject to the main benefit test. HMRC view the category A hallmarks as similar to several hallmarks under DOTAS and intends to take a similar approach in interpretation, linking to the relevant DOTAS guidance in the consultation document.

Specifically, in respect of standardised documentation, the consultation notes that under the equivalent DOTAS rules, arrangements such as ISAs and enterprise investment schemes are excluded. There is no express exclusion under the regulations on the basis of HMRC’s view that these kinds of products are not inherently caught by the main benefit test.

Category B: tax structured arrangements.

Again, these are all subject to the main benefit test. The most widely discussed of these is hallmark B2 which captures arrangements which have the effect of converting income into capital (or other categories of revenue taxed at a lower rate). Here the consultation treads a very fine line between situations where HMRC perceive that a conversion from income to capital has taken place and those situations where there is a legitimate commercial choice to be made between different commercial options. This is an area where further examples would be welcome. The example given is of employees given share options as part of their remuneration where any increase in value in the share options before exercise could be taxed as a capital gain rather than income. Whilst the employee could have received salary income instead, the employer has simply chosen between viable (normal) commercial options. The addition of steps which are contrived or outside normal commercial practice would be more likely to bring the arrangement within the hallmark. A point to note here is that “conversion” of income into capital does not necessarily require any pre-existing right to income.

Category C: cross-border payments and double deductions

Of all of the hallmarks under the Directive, this has raised the most concern that it may pick up standard transactions with no particular tax motive. It is not surprising that it generates the most questions and commentary in the consultation document.

There are some useful clarifications in relation to hallmark C1 (cross-border payments between associated persons)

  • The “recipient” of a payment will be the person taxable on its receipt so that, for example, for a partnership the partners will be treated as the recipient.
  • If the jurisdiction of residence of the recipient of a payment is not known to the intermediary who is a promoter it is unlikely to give rise to a reporting obligation.
  • A tax rate is “almost zero” if it is less than 1 per cent. This applies to the headline rate of tax, not the taxpayer’s The list of blacklisted countries should be examined on the day on which the reporting obligation arises. (The recent addition and removal of Bermuda from the blacklist begs the question of whether it is right to see the reporting obligation as arising on July 1, 2020, the first day of the specified period during which a report must be made, so that payments made before that date are not reportable.)
  • When considering whether a payment is tax exempt in the recipient’s jurisdiction, it is the nature of the payment, rather than the status of the recipient that must be exempt: an exempt body, such as a pension fund will not be automatically caught.

A number of practitioners had questioned whether hallmark C2 (requiring disclosure where depreciation is claimed in more than one jurisdiction) would lead to an absurd result where assets are acquired by branches, due to the inclusion and credit basis on which permanent establishments of UK entities are taxed. HMRC answers this in the consultation: arrangements will not be reportable where there is a corresponding taxation of profits from the asset in each jurisdiction where depreciation is also claimed (subject to any double taxation relief). Whilst this is not strictly in accordance with the drafting of the directive, which contains no such carve out, this is a welcome approach from HMRC as it will enable commercially-motivated transactions to proceed without the risk of being tainted by disclosure.

Category D: transparency

This hallmark looks at arrangements which have the effect of undermining CRS reporting or obscuring beneficial ownership. There is no main benefit test and the test is stated to be an objective one, so that the intention of the taxpayer is irrelevant. Having said this, the consultation goes on to say that arrangements which merely lead to no report under the CRS being made will not be undermining or circumventing the CRS provided that outcome is in line with the policy intentions of the CRS (the example given is using funds held in a bank account to invest in real estate, a category of investment specifically excluded from reporting under the CRS). As is often the case, the examples given in the consultation document ignore grey areas. Advising a person to transfer funds to a jurisdiction which has not implemented funds, in order to avoid reporting will, not surprisingly, be caught …

Here again the consultation anticipates that “promoters” will know whether arrangements undermine or circumvent CRS whereas a service provider” may not only have knowledge of a particular step and may not understand the effect of the arrangement as a whole, so may not be under an obligation to report.

The test at hallmark D2 (arrangements obscuring beneficial ownership) is whether beneficial owners can reasonably be identified by relevant tax authorities, including HMRC. This does require a public register of beneficial owners, but where there is a public register, the hallmark will clearly not apply. Examples of obscuring beneficial ownership include the use of undisclosed nominee shareholders or of jurisdictions where there is no requirement to keep, or mechanism to obtain, information on beneficial ownership. Helpfully, the consultation states that institutional investors or entities wholly owned by one or more institutional investors are outside this hallmark.

Category E: transfer pricing

Responding to questions raised during informal consultation, HMRC confirm that APAs are not unilateral safe harbours (but rather agreements as to correct pricing) and are therefore not caught by this hallmark. Other comments of interest relate to hallmark E3 (intragroup cross-border transfers). This hallmark applies where a cross-border transfer of functions/risks/assets is projected to result in a more than 50 per cent decrease in EBIT of the transferor(s) over the next three years. HMRC’s starting point is to consider this test at company, rather than group level (as that is how the UK corporation tax regime works) but this is being kept under review in recognition of the fact that many other jurisdictions have tax consolidation regimes and may take a different approach. The test looks at projected earnings, not what has actually happened: if the projections used in reaching a decision not to report are what a hypothetical informed observer would consider reasonable, there is no failure to comply whatever the real-world outcome. HMRC expect relevant entities to be producing the kind of projections required to apply this test and would not expect the taxpayer to need to make any special calculations for DAC 6.

Reporting – what, who and where

The regulations cross-reference the list of reportable information set out in the Directive and clarify that, to be reportable by an intermediary, information must be in the intermediary’s “knowledge, possession or control”. The consultation expands on this: an intermediary is not required to trawl through all of its computer systems to try to find all information held in relation to the relevant taxpayer in order to see if it might be relevant, but the intermediary will be expected to review the documents and information in relation to the reportable arrangement.

Reportable information

  • Identification of taxpayers and intermediaries, including
    • tax residence
    • Name, date and place of birth (if an individual)
    • Tax Identification Number (TIN)
    • Where appropriate, the associated persons of the relevant taxpayer.
  • Details of the relevant applicable hallmark(s).
  • A summary of the arrangement, including (in abstract terms) a summary of relevant business activities.
  • The date on which the first step in implementation was or will be made.
  • Details of the relevant local law.
  • The value of the cross-border reportable arrangement.
  • Identification of relevant taxpayers or any other person in any Member State likely to be affected by the arrangement.

This is a lot of detail. Whoever is making the report will clearly need to devote time to collating information

Where the report should be made

The Directive sets out a hierarchy to determine which member state a disclosure should be made in and this hierarchy is cross-referenced to in the draft regulations. The starting point is that the report should be made in the member state in which the intermediary is tax resident, failing which, in the location of a PE connected with the provision of the relevant services and, where neither apply, in the place of incorporation or, ultimately, in the member state where the professional association with which the intermediary is registered is located.

Disclosure only needs to be made once

A transaction is likely to involve a number of intermediaries. Disclosure only needs to be made once in respect of arrangements.

This means that no report needs to be made in the UK if

  • The intermediary has made a report in another EU member state
  • Another intermediary has made a report setting out (all) the information that the intermediary would have been required to report.

In either case, the intermediary needs to be able to evidence that the information that it would have been required to report has been reported, not simply that a report has been made. The consultation does not provide suggestions as to how the intermediary achieves this. The expectation is that the filing of a report will be evidenced by providing the “arrangement reference number” provided by HMRC or the relevant competent authority in other member states. However, determining whether the report made was comprehensive may be left to the intermediaries to work out between themselves.

Documented formal agreement as to who will make the report should be in place before the actual reporting obligation commences. It will be beneficial in transactions where disclosure is thought to be necessary to ensure that all parties involved are able to cooperate with the reporting process so that a single, comprehensive report can be submitted. Parties involved will want to consider rights of review and comment and will need to ensure that the making of the report will not breach any contractual terms, including terms of engagement. It may become practice in certain types of transaction to agree contractually who will undertake the reporting obligation and in what form.

Legal Professional Privilege

An intermediary unable to report due to legal professional privilege is required to inform other intermediaries of the fact and of their reporting obligations. As would be expected, this does not provide a blanket exclusion from a requirement to report: legal professional privilege only applies to information that is legally privileged. The consultation is clear therefore that lawyers may need to report non-privileged information and that much of the information to be reported will be factual and will not be privileged in nature. The examples given are of names of taxpayers and intermediaries and descriptions of the transactions undertaken. In practice, intermediaries may agree between themselves that reporting will be undertaken by an intermediary not subject to legal professional privilege who can make a single report including all the required information. The difficulty in this context is that a lawyer may possess information that is confidential to a client (and hence which the lawyer’s code of conduct would prohibit disclosure of) but which is not strictly legally privileged and so does not fall within the scope of the exemption. No doubt the boundaries of this rule will be tested over time.


The penalty regime draws on DOTAS and provides for penalties in a number of areas. The starting point for failure to report penalties or a failure to notify of reliance on legal privilege is a daily penalty of up to £600, but, as under the DOTAS regime, the First-tier Tribunal can impose fines of up to £1 million. There are also penalties of up to £5,000 for failure to failure to notify an arrangement reference number or to make three monthly returns in respect of marketable arrangements.

HMRC have stated that they will not impose penalties for a failure to disclose where the first step of the arrangement took place before the consultation was published and the failure is due to a lack of clarity around the obligations or interpretation of the rules. The implication is that, with the consultation document now in place, HMRC will expect intermediaries and taxpayers to have enough guidance to enable them to take a sensible, cautious approach to monitoring potentially reportable arrangements. There is also acknowledgment of the challenges faced by taxpayers in the absence of guidance, promised to be published “alongside the finalised regulations” before December 31, 2019, but no express assurance of leniency in respect of transactions entered into to that date. Taxpayers and intermediaries must approach the grey areas with caution and monitor and maintain a record of all potentially reportable arrangements.
