Code of Practice 8 (COP 8) Investigation Specialists

Home → Tax Investigations → Code of Practice 8 / COP 8

Code of Practice 8 (COP 8) investigations generally arise where HMRC suspects that a business or organisation has used tax avoidance schemes to underpay tax. COP 8 usually involves technical tax arguments and generally does not involve allegations of serious tax fraud, so it should remain a civil tax investigation if handled carefully. However, if during the process it appears that HMRC fraud is involved, then it could be upgraded to COP 9 or even a criminal tax fraud investigation.

COP 8 investigations do not have a standardised format and HMRC often focuses on gathering large amounts of information on a business or organisation. It is vital to understand which documents have the protection of privilege and the limitation of what HMRC can obtain.

Solicitor or Accountant?

If you are considering contacting an accountant or a solicitor regarding a COP 8 investigation, you should be aware that information you provide to your solicitor enjoys a special status called legal professional privilege.

Your accountant cannot provide this protection, although they may be able to gain it if they are instructed by a solicitor. If an assessment of the tax due is required, and there is to be a report prepared about your tax affairs, we can instruct an accountant on your behalf.
