Private Client analysis: The First-tier Tribunal (FTT) had previously addressed Mr Campbell’s appeal against HMRC’s assessments and penalties for income tax and Capital Gains Tax (CGT) related to residential property transactions. HMRC contended that Mr. Campbell’s purchase and sale of four properties between 2010 and 2016 constituted a trade, making him liable for income tax or, in the alternative, CGT. The FTT determined that Mr. Campbell was not engaged in a trade and, therefore, not subject to income tax. However, they upheld HMRC’s CGT assessments and penalties. Mr Campbell appealed on the CGT assessment, asserting he was eligible for main residence relief, while HMRC cross-appealed on the income tax issue, arguing that Mr Campbell was indeed trading. Both parties claimed there were errors of law in the FTT’s decisions. While the Upper Tribunal (UT) upheld the FTT’s ruling on the trading matter and dismissed HMRC’s cross-appeal, they identified multiple errors of law in the FTT’s CGT findings. Consequently, the UT set aside the FTT’s decisions on three of the four grounds of Mr. Campbell’s appeal, remitting them for reconsideration by a differently constituted FTT. Notably, the UT’s judgment was highly critical of many aspects of the FTT’s approach. Somewhat surprisingly, this did not extend to the determination that Mr. Campbell’s activities did not constitute a trade, which was not remitted back to the FTT.
