Tax Avoidance Schemes & Code of Practice 8 Investigations

HM Revenue and Customs (HMRC) may open a Code Of Practice 8 (COP 8) investigation against you if they believe that you are underpaying tax or have opened a tax avoidance scheme to reduce a tax liability. The Fraud Investigation Service (FIS) at HMRC can carry out a COP 8 investigation against any individual or business. The investigation can include any type of taxation (both direct and indirect). The COP 8 investigation is normally a civil tax investigation if carefully managed by expert legal Tax Solicitors. If HMRC’s case against you is successful, then you will be liable to pay back all the tax owed, interest accrued and penalties due. However even if HMRC’s position is established, liability for penalties can be challenged.

Tax Avoidance Schemes Advice

Code of Practice 8 investigations generally arise where HMRC suspect that artificial tax avoidance schemes have been used to underpay tax. HMRC defines tax avoidance as:

“[B]ending the rules of the tax system to gain a tax advantage that Parliament never intended. It often involves contrived, artificial transactions that serve little or no purpose other than to produce this advantage. It involves operating within the letter, but not the spirit, of the law.”

HM Revenue and Customs (HMRC)

Tax avoidance structures are used to minimise tax exposure and can be considered perfectly legal if a particular interpretation of tax legislation is applied. If the planning of a scheme has been challenged by HMRC, it is essential to consult legal tax specialists, because the adviser who promoted the scheme may lack the objective clarity to honestly review and defend the arrangement.

How to identify a Tax Avoidance scheme

HMRC offers the following guidance on the warning signs that you might be in a tax avoidance scheme:

What will HMRC do if they discover you are part of a Tax Avoidance scheme?

HMRC will investigate fully your tax affairs if it is discovered that you are part of a tax avoidance scheme. In addition, HMRC may also:

If you are implicated in a tax avoidance scheme, it is imperative to seek legal advice early. The implications for tax avoidance are serious, potentially leading to a prison sentence. Contact our dedicated team of London Tax Solicitors and Barristers today for urgent and confidential advice.

Examples of Tax Avoidance Schemes

Specialist Tax Solicitors should be consulted as soon as you enter into or suspect that you are part of tax avoidance scheme or are being investigated by HMRC. Examples of schemes that have formed part of a COP 8 notice include:

Artificial Surplus: Some pension schemes create an artificial surplus. The scheme purports to enable a member of a registered pension scheme to remove funds from the pension scheme tax free. This can be by artificially creating a funding surplus through the surrender of rights by a member.

Employer Financed Retirement Benefits Scheme (EFRBS): this unapproved pensions scheme involves the establishment of an offshore trust whereby an employer transfers funds and trustees apply funds via sub-trusts to the benefit of the employees.  This ensures that retirement benefits in the form of tax exempt or low tax amounts in the form of a loan.

The Code Of Practice 8 Investigation Procedure

Unlike for a COP 9 investigation, there is no standardised procedure for a COP 8 investigation. COP 8s primarily focus on gathering large amounts of information therefore it is essential to understand which documents are protected by privilege and what the limitations of HMRC’s powers are.

An approach utilised by HMRC in COP 8 cases is to challenge the interpretation of the tax legislation upon which the tax avoidance scheme relies upon. We are highly experienced in formulating argument s to persuade HMRC that their own interpretation of the tax legislation is incorrect and that the particular facts of our clients case do not warrant a COP 8 investigation. We have experience and are well prepared to argue your tax disputes cases in front of the independent First Tier Tax Tribunal.

Anyone subject to a COP 8 investigation should instruct us as expert Tax Solicitors to handle the COP 8 investigation procedure. We ensure that an active approach is taken to all Code of Practice investigations. We will attend any meetings with HMRC and ensure to identify and address HMRC’s main concerns early in the investigative process.

Our tax experts are highly experienced in collating and presenting the information requested by HMRC into a report which puts your case in context and presents technical tax arguments which may benefit your case. In addition, we will challenge HMRC if they request information which is outside the purview of the COP 8 investigation and we can apply to the Tax Tribunal for a Closure Notice if HMRC’s investigation is unjustified or unwarrantedly lengthy.

Can Tax Avoidance lead to criminal prosecution?

HMRC do not undertake a Code Of Practice 8 investigation with a view to criminal prosecution. However, they may take a different view if the suspicion of or evidence of fraud is discovered during the investigation. If serious tax fraud is suspected, then HMRC may open an investigation under Code of Practice 9.

Alternatively, if HMRC wish to conduct an investigation with a view to criminal prosecution, then they will investigate under the Police and Criminal Evidence Act (1984) (PACE 1984), the Criminal Procedure and Investigation Act (1996) and their respective Codes of Practice.
