Tax analysis: In Kwok, the First-tier Tax Tribunal (FTT) ordered HMRC to pay the taxpayer’s costs of and incidental to the appeal, following HMRC’s withdrawal five days before the listed hearing. However, the FTT refused to award costs on the indemnity basis because, although HMRC's conduct was unreasonable, including its late withdrawal from the case, this did not amount to being unreasonable to a high degree and the FTT also declined to summarily assess the taxpayer’s claimed costs, directing detailed assessment if the parties could not agree the amount.
