Beyond Kittel: When HMRC Alleges the Taxpayer Was the Fraudster
Beyond Kittel: When HMRC Alleges the Taxpayer Was the Fraudster
Most businesses facing a Kittel assessment believe they are dealing with a familiar allegation.
HMRC says that VAT fraud occurred somewhere within a supply chain and that the taxpayer either knew, or should have known, that its transactions were connected to that fraud.
Historically, that has been the central battleground in Kittel litigation.
However, an increasingly important development is emerging within some HMRC fraud investigations. Rather than merely alleging that a taxpayer knew about fraud committed by others, HMRC is increasingly advancing cases which effectively assert that the taxpayer itself was an active participant in the fraud.
This distinction is significant. It changes both the nature of the dispute and the way in which the evidence must be analysed.
Businesses facing these allegations should understand the difference.
What Is a Kittel Allegation?
The Kittel principle originates from the European Court of Justice decision in Axel Kittel v Belgian State and Recolta Recycling.
The principle allows HMRC to deny VAT input tax where:
- VAT fraud occurred within the supply chain; and
- the taxpayer knew, or should have known, that its transactions were connected with that fraud.
Importantly, a traditional Kittel case does not require HMRC to prove that the taxpayer committed the fraud itself.
Many Kittel disputes focus on whether the taxpayer had sufficient knowledge of fraud elsewhere in the supply chain and whether HMRC’s conclusions are properly supported by the evidence.

The Difference Between Knowledge and Participation
A crucial distinction exists between:
- knowing that transactions were connected to fraud; and
- being accused of participating in the fraud itself.
In many Kittel investigations, HMRC relies on what are commonly described as “means of knowledge” arguments.
HMRC may contend that a reasonable trader would have identified warning signs, carried out further enquiries or recognised that transactions were connected to fraudulent tax loss.
These cases are often highly fact-sensitive and involve detailed analysis of supply chains, commercial arrangements and due diligence.
However, some investigations go much further.
Rather than alleging constructive knowledge, HMRC may allege that the taxpayer was the orchestrator of the VAT fraud.
At that point, the dispute begins to move beyond a traditional Kittel analysis.
The Importance of the Italmoda Decision
One of the most significant authorities in this area is the decision of the Court of Justice of the European Union in Italmoda.
Whilst Kittel is often cited as the leading authority, Italmoda reinforced the wider principle that VAT rights can be denied where a taxpayer knowingly participates in VAT fraud or abuse.
The decision is important because it demonstrates that the courts are concerned not merely with passive knowledge but also with active participation in fraudulent arrangements.
For HMRC, this provides a basis for advancing allegations which go beyond the traditional “should have known” formulation.
How HMRC Pleads These Cases
We are increasingly encountering Statements of Case containing allegations such as:
- deliberate manipulation of VAT liabilities;
- orchestrated fraudulent arrangements;
- artificial transactions lacking commercial purpose;
- misuse of VAT registrations;
- false input tax claims;
- participation in fraudulent tax loss chains.
These allegations are fundamentally different from an assertion that a taxpayer merely failed to identify warning signs.
The practical effect is that HMRC may seek to portray the taxpayer as one of the architects of the fraud rather than simply a trader connected to it.
This often has significant consequences for the conduct of the litigation.
Why Commercial Purpose Becomes Critical
Once HMRC alleges participation in fraud, the focus frequently shifts towards commercial purpose.
Tribunals may be asked to consider questions such as:
- Why was a particular company established?
- Why were multiple companies used?
- Why were transactions structured in a particular way?
- What commercial benefit existed beyond VAT consequences?
- What services were actually provided?
- What evidence supports the commercial explanation?
Businesses are often surprised to discover that structures which appeared commercially sensible at the time are later portrayed by HMRC as lacking genuine economic substance.
For that reason, contemporaneous evidence can become extremely important.
Actual Knowledge, Blind-Eye Knowledge and Fraud Allegations
Many taxpayers assume there are only two categories:
- innocent behaviour; and
- actual dishonesty.
The reality is often more complicated.
HMRC frequently relies upon concepts such as:
- actual knowledge;
- means of knowledge;
- blind-eye knowledge;
- deliberate ignorance; and
- participation in fraud.
As a result, disputes can become highly technical and fact-specific.
The legal arguments may involve detailed consideration of what information was available to directors, what enquiries were made and whether commercial explanations withstand scrutiny.
Why Early Advice Matters
One of the most common mistakes businesses make is treating a serious Kittel investigation as a routine VAT enquiry.
By the time a formal decision is issued, HMRC may already have developed a detailed theory of the case.
Where allegations involve participation in fraud rather than mere knowledge, the risks can increase significantly.
Early specialist advice can assist with:
- analysing HMRC’s allegations;
- identifying weaknesses in HMRC’s reasoning;
- preserving relevant evidence;
- preparing witness evidence;
- assessing litigation risk; and
- developing an effective Tribunal strategy.

Defending Serious Kittel Allegations
Successful defence of serious Kittel allegations requires far more than demonstrating that standard due diligence checks were carried out.
Where HMRC alleges active participation in fraud, the focus often shifts to:
- commercial reality;
- transaction analysis;
- documentary evidence;
- witness credibility;
- supply-chain reconstruction; and
- the overall plausibility of HMRC’s allegations.
These cases are among the most complex disputes heard by the Tax Tribunal.
