Code of Practice 9 (COP 9) Investigations

A COP 9 investigation can be complex and stressful.

COP 9 investigations are initiated by HMRC where they believe that a serious tax fraud has been committed or tax liabilities have been deliberately avoided.

Under the COP 9 process a one-time opportunity is typically given for a full disclosure to be made using what is known as the Contractual Disclosure Facility (CDF), potentially avoiding escalation to a full criminal investigation. We can assist with the preparation of your case and formulating a CDF disclosure.

Our experienced team have an excellent record in managing such investigations to agreeable outcomes which include mitigation of tax and penalty loadings. It is important that our intervention is sought early so that we have the time to assimilate the necessary information to help you in your case.

Alternatively, if an ongoing COP 9 investigation appears to be heading in the wrong direction we are happy to offer a new perspective with a view to resolving an impasse and reaching a satisfactory settlement with HMRC which may include the Alternative Dispute Resolution (ADR) process.
