Let’s be honest: nobody jumps for joy when a brown envelope from HMRC lands on the doormat. Usually, it’s just a routine query or a nudge about a tax return. But then there are the letters that make your heart skip a beat: the ones from the HMRC FIS (Fraud Investigation Service).
If you’ve received a letter mentioning COP9 or COP8, you’re not just dealing with a standard tax check. You’re dealing with the "Special Forces" of the tax world. At Makes Sense Accountants, we’ve seen it all, and while these investigations are serious, they aren’t the end of the world: provided you handle them the right way.
In this guide, I’m going to break down exactly what these investigations mean, why they happen, and why you definitely shouldn't try to navigate them alone.
What is the HMRC FIS?
The Fraud Investigation Service (FIS) is the elite arm of HMRC. Their job isn’t to look at a small mistake on a VAT return; their job is to tackle the big stuff. We’re talking about suspected serious tax fraud, complex tax avoidance, and offshore non-compliance.
When the FIS gets involved, it means HMRC believes there is a significant amount of tax at stake. They have more resources, more powers, and: to be frank: more persistence than your average tax inspector. They are there to recover money, and they aren’t easily swayed by "I forgot to tell my bookkeeper."
Understanding COP9: The Serious One
If you get a letter saying you are being investigated under Code of Practice 9 (COP9), it means HMRC suspects you of "deliberate conduct." In plain English: they think you’ve committed tax fraud.
Now, don't panic just yet. The COP9 process is actually designed to give you a "way out" through something called the Contractual Disclosure Facility (CDF).
How COP9 and the CDF Work
HMRC essentially says to you: "We think you’ve been dishonest. If you admit it, tell us everything, and pay what you owe (plus interest and penalties), we won't prosecute you criminally."
It’s a deal. You get immunity from criminal prosecution in exchange for full, honest disclosure. But there’s a catch: you only have 60 days to decide if you want to take the deal.
- The 60-Day Deadline: You have to decide whether to accept the offer of the CDF. If you reject it or ignore it, HMRC can (and often will) start a criminal investigation.
- The Outline Disclosure: You have to provide a basic summary of what went wrong and how much tax you think is involved.
- The Full Disclosure: Once the outline is accepted, you (usually with the help of someone like us at Makes Sense Accountants) prepare a massive, detailed report covering the last 20 years of your tax affairs.

What is COP8? The "Avoidance" Route
If you receive a COP8 letter, the vibe is a bit different, but no less serious. COP8 is used when HMRC doesn't necessarily suspect "fraud" (yet), but they believe you’ve used a complex tax avoidance scheme or that there are huge losses to the Treasury that need looking into.
In a COP8 investigation, there is no offer of immunity from prosecution. HMRC is basically saying, "We don't think this tax scheme you used works, and we want the money back."
The tricky part? If HMRC starts a COP8 investigation and finds evidence that you were being intentionally dishonest, they can upgrade it to a COP9 investigation at any time.
Why Me? Common Triggers for FIS Activity
You might be wondering how you ended up on their radar. HMRC’s "Connect" computer system is incredibly powerful. It pulls data from bank accounts, the Land Registry, social media, and even offshore jurisdictions.
Common reasons for an FIS investigation include:
- Offshore Assets: Failing to declare income from properties or bank accounts held abroad.
- Lifestyle Mismatch: If your lifestyle (fancy cars, luxury holidays) doesn't match the income you’ve declared on your tax returns.
- Whistleblowers: Sometimes, a disgruntled former employee or an ex-partner decides to have a word with HMRC.
- Complex Schemes: Participation in aggressive tax planning schemes that HMRC has flagged.
Why Professional Advice is Crucial
I’m going to be blunt: responding to a COP9 or COP8 letter yourself is a recipe for disaster. This isn't just about "doing the math"; it’s about legal strategy, negotiation, and managing a very high-stakes process.
We Are Your Buffer
At Makes Sense Accountants, we act as the shield between you and HMRC. When the FIS calls, they are looking for information they can use. We handle all the correspondence. We translate their technical jargon into plain English for you, and we translate your situation into a professional, robust report for them.
We Manage the Stress
A tax investigation: especially one involving the FIS: can drag on for years. The stress of having that hanging over your head is enormous. Our job is to take that weight off your shoulders. We manage the deadlines, we attend the meetings, and we ensure you aren't being bullied into paying more than you legally owe.
Accuracy is Everything
In a COP9 case, if you leave something out of your disclosure, your immunity from prosecution can be revoked. You cannot afford to make a mistake. We dig deep into the figures to make sure the disclosure is "full and frank," protecting you from further legal trouble.
Don't Face HMRC Alone
If you’ve received a letter from the Fraud Investigation Service, the clock is already ticking. Whether it’s a COP8 or a COP9, the decisions you make in the first few weeks will determine the outcome for the next few years of your life.
At Makes Sense Accountants, we don’t judge. We’re here to help you navigate the system, minimize the damage, and get back to running your business and living your life.
I’ve spent years helping clients through the most complex tax situations imaginable. We know how HMRC thinks, and we know how to present your case in the best possible light. Whether you need help with proactive tax planning to stay out of trouble in the first place, or you’re already in the middle of a storm, we’ve got your back.
The Long and Short of It
HMRC is getting more aggressive. The FIS is better funded than ever. If "COP9" comes calling, it’s time to stop DIY-ing your taxes and bring in the professionals.
