Should I approach Solicitors, Accountants or both?

If you are considering contacting an accountant or a solicitor regarding any tax Investigation, we would advise, initially, to instruct a firm of specialist solicitors.

Any information provided is confidential, enjoying the special status of ‘‘legal professional privilege’.

An accountant cannot provide this protection and, accordingly, we are able to provide a filter and barrier between you and HMRC.

However, it is not our role to advise on financial assessments of tax alleged to be due and we work very closely with Tax Accountants who we are happy to instruct.

The types of investigation we can help with fall into the following categories:

  • Initial assessment of tax liability
  • COP8
  • COP9 and the Contractual Disclosure Facility
  • Criminal Investigation and Prosecution

Appealing Disputed Assessments

If an assessment has been issued by HMRC with which you disagree, it is possible to appeal the same before a Tax Tribunal.

An appeal has to be lodged with the First Tier Tribunal within thirty days and, accordingly, speed is essential.

The First Tier Tribunal is responsible for handling appeals against decisions made by HMRC on the following:

Income Tax PAYE tax
Corporation Tax Capital Gains Tax
National Insurance Contributions Statutory Sick Pay
Statutory Maternity Pay Inheritance Tax
VAT Excise duty
Customs duty

Tribunal Procedure

The Tribunal is a court of law which examines the evidence presented to it upon an appeal and upon which the Judge will reach his decision on the balance of probabilities, having regard to all the circumstances.

Code of Practice 8

If HMRC believes that large amounts of tax has been underpaid as a result of complex tax arrangements or tax avoidance schemes which have been implemented by a large number of taxpayers then they will initiate a ‘COP8’ enquiry.

Although HMRC state that they commence these investigations without intent to prosecute, it is imperative to seek proper and experienced legal advice to avoid incriminating yourself.

The Procedure | Code of Practice 8

The investigation is normally conducted by the Fraud and Bespoke Avoidance section of the Special Directorate of HMRC, which, if there is suspicion of a serious tax loss to HMRC, will investigate the affairs of:

1. Individuals

2. Partnerships

3. Companies

4. Trusts

All available information will be closely examined including tax returns, accounts and bank statements, for example.

During the course of the investigation you may be subjected to meetings with HMRC and/or visits from HMRC to your business premises to examine your business and private financial records.

 Code of Practice 9 | Contractual Disclosure Facility

Where a criminal investigation has not already commenced, HMRC may decide to initiate an investigation into an individual using the Code of Practice 9 (COP9) investigation of fraud procedure when tax fraud/tax evasion is suspected.

The recipient of COP9 is given the opportunity to make a complete and accurate disclosure of all deliberate and non-deliberate conduct that has led to irregularities in their tax affairs.

This is completed by way of a contractual arrangement called a Contractual Disclosure Facility (CDF).

However, HMRC may commence a criminal investigation if it is felt that:

  • a full and frank disclosure has not been made or
  • it is considered that false and/or misleading statements have been made
  • in exchange for COP9, if HMRC concludes that full disclosure of all deliberate conduct has ben made, a criminal investigation will not be pursued.

HMRC will not normally disclose any specific suspicions but will seek voluntary disclosure and it is crucial that specialist advice is taken in order to protect yourself against incrimination.

COP9 | What are my options and what are the risks?

If you decide to reject a COP 9 offer then you will not be bound by the terms of a CDF but you may be at risk of HMRC pursuing a criminal investigation.

If you accept the offer, you will be required to accurately complete and return an Outline Disclosure Form (ODF).

If the ODF is not fully completed, HMRC will not be bound to comply with the CDF and may initiate a criminal investigation.

COP9 | What are my obligations if I accept? | Outline and Full Disclosure to HMRC
When the ODF is being completed, for each separate tax loss that arose as a result of your deliberate conduct, you will need to explain:

  • what you did
  • how you did it
  • the involvement of other people and entities
  • how you benefited from the deliberate conduct

In some instances you may be asked to provide a Disclosure Report which will require:

  • a brief business history
  • a description of all tax irregularities (including any that were brought about by non-deliberate conduct)
  • quantification of all the irregularities
  • information to show how you quantified the irregularities
  • summaries of tax and/or duties, interest and penalties due
  • a reconciliation of your irregularities figure with the summary of tax and/or duties
  • a certified statement of worldwide assets and liabilities
  • certificates of bank accounts and credit cards you operated

You will also be expected to certify that the report is correct and complete.
