The FTT concluded that the evidence derived from the sale price of shares on the [Alternative Investment Market](https://www.londonstockexchange.com/raise-finance/equity/aim) (AIM) held greater reliability compared to evidence presented by an expert valuer employed by [HMRC](https://www.gov.uk/government/organisations/hm-revenue-customs), ultimately resulting in the allowance of the taxpayers' appeals. ## Graham Chisnall and Others v HMRC Graham Chisnall, Frank Cocker, and Neil Mcarther (the Appellants) made charitable gifts of shares listed on the Alternative Investment Market (AIM) during the 2004/05 tax year. Among these shares were those of Frenkel Topping plc (Frenkel) and Vista Group plc (Vista). The Appellants claimed income tax deductions under section 587B, Income and Corporation Taxes Act 1988, based on their valuations of the shares. HMRC conducted enquiries into the valuations, leading to disagreements over the share values and subsequent appeals to the FTT. The Appellants also sought an order from the FTT, under Rule 8 of the Tribunal Rules, based on HMRC's alleged inordinate and inexcusable delay. ## UK Tax Tribunal’s Decision The FTT ruled in favor of the Appellants, emphasising the reliability of evidence derived from the actual share prices on the AIM over HMRC's expert reports. Despite the HMRC-employed expert's testimony, the FTT questioned the credibility of their evidence, particularly regarding the valuation process. The FTT ultimately favoured the valuations provided by the Appellants in their tax returns, highlighting the importance of transparent and justifiable expert opinions in such disputes. The FTT's decision serves as a cautionary tale for HMRC regarding the impartiality and credibility of expert evidence in tax disputes. By highlighting the need for clear justifications and consistency in valuation methodologies, the case underscores the importance of rigorous scrutiny in tax proceedings. The FTT referenced *McArthur and Bloxham v HMRC [2021] UKFTT 237 (TC)* at [15] and *Netley v HMRC [2017] UKFTT 442 (TC)* at [203] in its decision, providing additional context on the determination of market value and setting precedents for future cases involving expert testimony. ## Download the Tax Tribunal Judgment [![](https://taxdisputes.co.uk/wp-content/uploads/2024/02/Graham-Chisnall-and-Others-v-HMRC-2023-UKFTT-857-TC-724x1024.jpg)](https://taxdisputes.co.uk/wp-content/uploads/2024/02/Graham-Chisnall-and-Others-v-HMRC-2023-UKFTT-857-TC.pdf) ## How LEXLAW Help with Tax Disputes At LEXLAW, we specialise in navigating complex tax disputes and providing tailored solutions to protect our clients' interests.
