Understanding COP9 and Its Impact
When HMRC issues a Code of Practice 9 (COP9) letter, it is one of the most serious actions a taxpayer can face. This is not about a late payment or an accidental miscalculation. COP9 means HMRC’s Fraud Investigation Service (FIS) suspects deliberate tax fraud—a calculated attempt to underpay or avoid tax.
Unlike routine tax enquiries, COP9 investigations have the potential to become criminal prosecutions. But HMRC also offers a lifeline: the Contractual Disclosure Facility (CDF), a one-time opportunity to admit fraud, disclose fully, and avoid prison.
What Is Code of Practice 9?
COP9 is HMRC’s civil procedure for tackling suspected tax fraud. It is designed for cases where HMRC has strong reasons to believe fraud has occurred but is prepared to resolve the matter without criminal proceedings if the taxpayer cooperates.
Why COP9 Is Different from Normal Tax Investigations
- COP9 = fraud suspicion → not carelessness or innocent mistakes.
- Civil vs. criminal → with cooperation, matters stay civil. Without it, criminal prosecution is possible.
- Personal stakes → your finances, your reputation, and in some cases, your liberty are on the line.
The Contractual Disclosure Facility (CDF) Explained
When you receive a COP9 letter, HMRC gives you two stark options through the CDF.
Option 1: Admit Fraud and Cooperate
By accepting the CDF, you:
- Make a full and honest disclosure of all tax fraud within 60 days.
- Provide an outline disclosure followed by a detailed report.
- Repay the underpaid tax plus interest.
- Face financial penalties, but crucially avoid criminal prosecution.
Option 2: Deny Fraud
If you sign to deny fraud:
- HMRC continues its investigation.
- If fraud is later proven, you may face criminal charges.
- Penalties are harsher, and prosecution can result in unlimited fines or prison sentences.
The 60-Day Deadline
Taxpayers have 60 days from receiving the COP9 letter to decide whether to admit fraud. This is a critical period where expert advice can make the difference between safeguarding your future or facing severe consequences.
What Happens During the 60 Days?
- You must prepare an Outline Disclosure: a summary of all tax fraud committed.
- HMRC will review and decide whether to accept it.
- If accepted, you move to the next phase: a Detailed Disclosure Report.
Disclosure Reports and Settlement Process
Once the outline is accepted, taxpayers must prepare a comprehensive Disclosure Report, often with professional assistance.
What the Disclosure Report Includes
- Full details of all fraudulent behaviour.
- Financial records and evidence supporting the disclosure.
- A statement of cooperation and willingness to settle.
Settlement Outcomes
- Repayment of tax owed.
- Interest charges.
- Penalties ranging from 20% to 200% of the tax, depending on the seriousness and cooperation.
- Avoidance of criminal prosecution if disclosure is complete and honest.

Code of Practice 9 Penalties and How They Are Calculated
HMRC uses a penalty framework based on three factors:
1. Deliberate Behavior
Fraud penalties are far higher than those for careless or innocent errors.
2. Telling, Helping, Giving Access
Penalties are reduced if you:
- Tell HMRC about the fraud early.
- Help them understand the scale of the fraud.
- Give access to records and documents.
3. Offshore Matters
Tax fraud involving offshore accounts or hidden income often attracts the highest penalties.
Frequently Asked Questions About COP9
Is COP9 a Criminal Investigation?
Not immediately. COP9 is a civil investigation. However, if you refuse to cooperate or make a false disclosure, HMRC may switch to a criminal investigation.
What Happens If I Ignore the COP9 Letter?
Failure to respond within 60 days means HMRC will proceed without your cooperation—often escalating to criminal prosecution.
Can I Get a Reduced Penalty?
Yes. Full, honest disclosure significantly reduces penalties, sometimes by more than half.
Should I Get Professional Advice?
Absolutely. COP9 is complex, and mistakes can have life-altering consequences. Tax fraud specialists can guide disclosure, negotiate penalties, and protect against prosecution.
Why COP9 “Gets Personal”
Unlike routine tax disputes, COP9 is direct and confrontational. HMRC is saying: “We believe you have been dishonest.” This is not just about money—it’s about integrity, trust, and potential damage to your reputation, business, and freedom.
The Psychological Pressure
- Receiving a Code of Practice 9 letter can be overwhelming and isolating.
- The 60-day clock adds immense stress.
- Decisions made in panic can worsen outcomes.
The Way Forward
By treating COP9 with seriousness, cooperating fully, and seeking expert help, taxpayers can resolve the matter without destroying their future. The process is tough, but it is designed to reward honesty and penalise deceit.
