COP9 Investigation Support – Specialist Criminal Defence

Received a COP9 investigation letter from HMRC? Act immediately — this is a serious matter. At Strix Accountancy, our experienced tax specialists provide confidential, expert support and representation to protect your interests and help you navigate HMRC’s investigation process with confidence.

COP9 Investigation Support

A COP9 investigation support case begins when HMRC believes there may be deliberate wrongdoing or serious irregularities in your financial records. This isn’t a routine enquiry — it’s part of the Contractual Disclosure Facility (CDF), which gives you a single opportunity to disclose issues in return for avoiding criminal prosecution.

Because the stakes are high, you need immediate specialist guidance. Any delay, unclear response, or misunderstanding of the CDF process can increase your legal and financial exposure.

At Strix Accountancy, we specialise in providing COP9 investigation support with complete discretion. Our experienced team reviews your situation, prepares accurate disclosures, and handles all communication with HMRC to protect your position and work toward the strongest possible outcome.
