Suspected Deliberate Tax Fraud Defence – How We Protect You From HMRC
Being accused of deliberate tax fraud by HMRC is one of the most serious situations a taxpayer can face. Whether the allegation comes through a COP9 letter, a discovery assessment claiming “deliberate behaviour”, or questioning during an investigation, the consequences can be severe. HMRC may demand tax for up to 20 years, impose heavy penalties, or even consider criminal proceedings.
But here’s what most people don’t realise: HMRC often gets it wrong.
A deliberate fraud allegation does not automatically mean deliberate behaviour took place. In many cases, HMRC misinterprets records, jumps to conclusions, or relies on incomplete data. That is why the most important thing you can do is build a strong, expert defence as early as possible.
At Tax Investigation Helpline, we specialise in defending individuals, sole traders, and companies accused of deliberate tax fraud. With the right strategy, pressure, and challenge, we can often reduce or remove the allegation entirely.

Why HMRC Suspects Deliberate Tax Fraud
HMRC typically alleges deliberate behaviour when they believe someone intentionally:
- Understated income
- Suppressed sales
- Created false records
- Manipulated accounts
- Failed to declare offshore income
- Used cash to hide turnover
- Claimed inflated or fake expenses
- Withheld key information during enquiries
However, HMRC’s interpretation is not always correct. What they call “deliberate” is often:
- A misunderstanding
- Poor record-keeping
- A bookkeeping error
- A technical accounting mistake
- A historical oversight
- Advice taken from a previous accountant
- A difference in interpretation
The Risks If You Do Nothing
If HMRC claims deliberate behaviour and you do not defend yourself properly, you may face:
- 20 years of tax assessments
- Up to 100% penalties
- Interest across all years
- Seizure of assets in severe cases
- A potential shift into criminal investigation
Even worse, HMRC’s assumption of deliberate behaviour can affect:
- Your credit rating
- Your business reputation
- Your directorship status
- Your future dealings with HMRC
The earlier you take action, the better your chances of preventing escalation.
How Tax Investigation Helpline Defends You Against HMRC’s Allegations
When HMRC accuses someone of deliberate tax fraud, the defence strategy must be precise, evidence-based, and professionally structured. Here is how we build a successful defence:
1. We Take Over Communication and Stop the Pressure Immediately: Once we represent you, HMRC must deal with us, not you. This protects you from:
- Saying something that is misinterpreted
- Being pressured into admissions
- Providing records without context
- Allowing HMRC to widen the scope
This first step alone prevents many cases from becoming far worse.
2. We Analyse HMRC’s Case and Identify the Weak Points
HMRC must prove deliberate behaviour, not simply assume it. We examine:
- The evidence they rely on
- Any gaps or inconsistencies
- Whether their interpretation is justified
- Flaws in their calculations
- Whether statutory time limits have been breached
3. We Hold HMRC to Account
A crucial part of your defence is ensuring HMRC follows the law correctly. We challenge:
- Incorrect behaviour classifications
- Unsupported assumptions
- Overstated assessments
- Unlawful information requests
- Procedural errors
- Penalties issued without proper basis
4. We Build a Strong Explanation Supported by Evidence-To overturn a deliberate allegation, you must show:
- The behaviour was not intentional
- A reasonable explanation exists
- Your actions were careless at worst
- Records support your position
- The issue arose from error, oversight, or misunderstanding
5. We Reduce or Eliminate Penalties and Years Assessed-A successful defence can lead to:
- Deliberate → Careless (removing 20-year lookback)
- Careless → No behaviour (removing penalties entirely)
- Withdrawal of assessments
- Large reductions in tax, penalties, and interest
