When we examined tax reliefs in 2014 we found that HMRC published estimates of only 46 reliefs which had economic and social objectives.35 Since then HMRC has responded to our recommendations that it be more transparent. In October 2019, it published for the first time a list of all 362 tax reliefs with economic and social objectives.36 It has now reported costs for 158 of these reliefs and plans to reports costs for more reliefs over the next two years.37 However, in its public reporting HMRC does not compare the cost of tax reliefs to published forecasts.38
