VAT MTIC Fraud Expert Witness UK

Missing Trader Intra-Community (MTIC) fraud is one of the most complex areas of UK VAT dispute. HMRC denies input tax to businesses connected to fraudulent VAT chains, even innocent traders, where it can demonstrate actual or constructive knowledge of the fraud connection. The knowledge test, established in Mobilx Ltd v HMRC [2010], requires HMRC to prove that the taxpayer knew or should have known that its transactions were connected to MTIC fraud.

Tax expert witnesses play a decisive role in MTIC disputes by analysing the due diligence conducted by the appellant, assessing red flags present in the transaction chain, and determining whether the knowledge test is met on the facts. Robust expert evidence on the knowledge test, combined with strong written representations, has resulted in HMRC cancelling VAT assessments and penalties entirely, including cases involving assessments exceeding £1.3 million.

Recent MTIC enforcement has seen HMRC issuing substantial input tax denial assessments, but expert challenge of HMRC's position on the knowledge test and transaction analysis has achieved significant successes. Early instruction of a VAT specialist tax expert witness is essential to build the evidential foundation before FTT proceedings.
