Chancellor’s speech aims to criminalise the tax avoidance industry.

It wasn’t mentioned in the Chancellor’s speech, but the Spring Statement papers contain a significant suite of anti-tax avoidance proposals, probably the toughest ever introduced.

The Government is getting serious – for the first time, there is a proposal to criminalise the promoters’ activity. If the Government follows through and HMRC uses these new powers, we could all be billions of pounds better off.

The ANTI-TAX AVOIDANCE PROPOSALS include:-

1. Criminalising breach of DOTAS
2. Stop notices that apply to everyone using the scheme or a similar scheme
3. New stop notices that can be sent to banks or others facilitating the scheme
4. New DOTAS civil penalties
5. An end to legal privilege when avoidance schemes are promoted as backed by a KC's opinion

These new anti-avoidance proposals should be welcomed by everyone who wishes to see the tax avoidance industry ended. If enacted, this will, in effect, criminalise the tax avoidance industry.

RADICAL ANTI-AVOIDANCE MEASURES HIDDEN IN THE SPRING STATEMENT

Dan Neidle @ Tax Policy Associates says:-

It wasn’t mentioned in the Chancellor’s speech, but the Spring Statement papers contain a major suite of anti-tax avoidance proposals, probably the toughest ever introduced. If enacted this will, in effect, criminalise the tax avoidance industry. We welcome it.

There is a mini-industry of creating tax avoidance schemes which have no prospect of success. We don’t believe one has succeeded in court in the last twenty years. That hasn’t stopped promoters from collecting millions in fees. The long series of new laws introduced to stop them have been ignored.

The Government is getting serious – for the first time, there is a proposal to criminalise the promoters’ activity. If the Government follows through and HMRC uses these new powers, we could all be billions of pounds better off.

I was less than flattering about the Autumn Budget, particularly the national insurance increase, farming inheritance tax change, and general failure to include any tax reform measures. However, the new anti-avoidance proposals are excellent and should be welcomed by everyone who wishes to see the tax avoidance industry ended.

Dan Neidle @ Tax Policy Associates HAS summarised the proposals below with his initial thoughts.  

CRIMINALISING DOOMED SCHEMES

HMRC has a power to issue a “stop notice” to the promoter of a tax scheme, making further promotion of that tax scheme a criminal offence.¹ The problem is that HMRC will issue a stop notice to one entity, and the promoter will simply move its business to another.²

The Government is proposing a “universal stop notice“. This would empower HMRC to issue a notice specifying a scheme; no person could then promote or enable that or any similar scheme. Anyone who did would commit a criminal offence, as would any person controlling or influencing them.

The proposals go further. The Government would be able to issue a “promoter action notice” to third parties who facilitate the scheme:

This is important; promoters have, for some time, been using offshore entities to make it harder for HMRC to take action against them. However, any business targeting UK clients is inevitably going to rely on banks, social media etc in the UK – so it makes sense to enable HMRC to target.

I would, however, be a little concerned about overreach (and I sense the Government is too). I would personally suggest making these powers apply only where either the individual promoter or their entity is outside the UK. This should be a fallback option, not the first line of attack.

CRIMINALISING BREACHES OF DOTAS

One of HMRC’s most important weapons against tax avoidance is DOTAS – the rules requiring promoters of tax avoidance schemes to disclose the schemes to HMRC. That has two consequences:

• HMRC gets early warning of schemes and can close them down.
• Anyone looking to use the scheme receives warning that it is classed as an avoidance scheme (because they must put a DOTAS reference number on their tax return).

DOTAS is therefore a serious threat to promoters’ business, and promoters deal with this by simply ignoring it (often based upon frivolous legal arguments, typically followed by promoters simply letting their firms fail).

I believe that, of the many tax avoidance schemes we’ve reported on, not one was disclosed under DOTAS. They all should have been.

We have therefore called for failure to comply with DOTAS to become a criminal offence for the individuals responsible, with strong protections to prevent innocent mistakes being penalised. So I’m delighted to see that is what the consultation paper proposes (with a “reasonable excuse” defence, so that innocent people aren’t caught).

There isn’t much detail in the document (that’s typical at this stage). But we will be responding to the consultation proposing that the criminal offence apply to the company’s directors and shadow directors.

We will also ask for a clear statement that the criminal offence will never be used against normal advisers or commercial parties who made an innocent mistake. One way to differentiate the bad actors from normal advisers would be to make the criminal offence only apply where a scheme is mass-marketed, or there is a premium fee (i.e. reflecting more than an adviser’s usual hourly rate). Other approaches could be considered.

EXPANDING DOTAS

The Government is proposing a new DOTAS hallmark to more clearly target disguised remuneration schemes.

These schemes are rampant – often pushing people on modest or low earnings into complex avoidance schemes (which aren’t properly explained and are sometimes hidden). The result: loss of tax for HMRC, and often large liabilities for the (often unwitting) scheme users.

It’s our view that all the disguised remuneration schemes are already covered by DOTAS, but perhaps the intention is to make it easier to deploy the new criminal offence against them?

INCREASING DOTAS PENALTIES

Another problem with DOTAS: the penalties is too low.

The standard penalties are currently £600 per day, or up to £1m. This is determined not by HMRC but by a tax tribunal. That delays the day of reckoning for promoters; by the time the tribunal hears the case, the fees have often been made, and cash extracted from the promoter’s business.

The consultation proposes allowing HMRC to charge a penalty, with a right of appeal to a tribunal. That is a sensible step to speed things up.

But there are other problems: even £1m is an insufficient deterrent when a promoter can make millions of pounds of fees in a few months. And promoters typically don’t stick around to pay penalties. So, we would suggest:

• The penalty should be geared to the fees received by the promoter (say 200% of fees) or, where a promoter does not adequately disclose the fees received, such amount as is just and reasonable under the circumstances.
• A promoter’s directors/owners should always be joint and severally liable for the penalties. Right now it’s too easy for them to walk away from their company.³

NEW INFORMATION POWERS

HMRC has extensive powers to require information from taxpayers using “information notices”. Normal taxpayers take information notices extremely seriously. Tax avoidance scheme promoters typically ignore them, and HMRC often struggles to impose penalties, not least because of the opaque ownership structures used by the promoters.

So the consultation proposes the creation of new information powers, backed up by criminal offences.

TARGETING LEGAL PROFESSIONALS

Many tax avoidance schemes are facilitated by a small number of legal professionals (almost exclusively barristers). We have published a series of examples.

The barristers provide opinions that the schemes are lawful, and DOTAS disclosure is not required. The courts almost always conclude the opposite. But the role of the barrister was not really to provide correct advice; it was to facilitate the scheme. The promoters can then claim, “we have a KC opinion”. When the opinion turns out to be wrong⁴, the end-users of the scheme cannot sue the KC, because they weren’t the client – the promoter was. And the promoter has done just fine.⁵

The opinion serves two purposes. It greatly helps marketing the scheme. And it gives the promoters a defence against penalties or criminal prosecution – after all, they received legal advice. The advice itself will almost always be privileged – HMRC cannot see it.

This is, in our view, corrupt. Jolyon Maugham KC wrote about the problem eleven years ago; nothing has been done. Ideally the Bar Standards Board would act.

The consultation contains a series of somewhat tentative proposals. Likely the most impactful are:

• Enabling HMRC to publish the names of lawyers who design tax avoidance schemes.
• Waiving legal privilege where a tax avoidance scheme is marketed as being supported by a legal opinion.

It seems HMRC and the Government also share our view that the professional regulators need to be more effective:

WHAT ELSE IS REQUIRED?

The most important element is simply resources. If these new rules are enacted and just added to HMRC’s toolbox, they will be rarely used.

HMRC should create a specialist team whose only role is pursuing civil and criminal penalties against tax avoidance scheme promoters. It would sometimes accept referrals from others within HMRC, and sometimes act on its own initiative. It would be staffed by a mixture of tax specialists, investigators, and white-collar crime lawyers.⁶

There are additional minor and costless measures HMRC should adopt.

• Currently, when tax avoidance schemes and their promoters are publicly named by HMRC, this is only for twelve months. After that, their name is taken off the list (although at least one excellent website preserves the listing forever). The one-year expiry date should be ended.
• Particularly egregious schemes are often considered by the General Anti-Abuse Rule Advisory Panel. The GAAR panel publishes its opinions; but the firms involved are not named. They should be.

NOTES

• 1 = “Stop notices” were a new power granted to HMRC in 2021, with the rules now in section 236A Finance Act 2014. The effect of a stop notice is that the recipient of the stop notice mustn’t promote the specified arrangements, or anything similar to them. The stop notice also requires the recipient to provide HMRC with detailed information on its clients, and to pass details of the stop notice to those clients.
• 2 = In theory the existing rules should deal with that. The effect of a stop notice also applies to (amongst others) anyone who controls, or has significant influence, over the recipient of the stop notice. And if the recipient transfers its business to another person, then the stop notice applies to them too. All of this is in theory: in practice the entities tend to be offshore and highly opaque, and it is difficult or impossible for HMRC to prove the relationship between them.
• 3 = i.e. expanding HMRC’s existing powers by removing conditions B and D – HMRC should simply be able to pursue directors/participators as soon as a DOTAS penalty is issued.
• 4= Either because frivolous legal positions were taken, or indefensible assumptions of fact were made
• 5 = Interestingly this doesn’t seem to be the case for Setu Kamal’s opinions for the Arka Wealth scheme – he seems to really give opinions to end users. The scheme may be laughable, but at least the users get some legal recourse (although possibly Mr Kamal has little practical exposure given he’s based outside the UK).
• 6 = To be clear, this is not a job-creation scheme for me – I’m retired from full time work and, even if I wasn’t, I don’t have the right skillset for such a job.
