Tax reliefs are an important feature of the UK tax system, and His Majesty’s Revenue and Customs has invested significant resources in improving understanding of their cost and effectiveness. Since 2019, it has produced costings for 350 reliefs, including detailed analysis of the 38 largest non-structural reliefs, which cost more than £500 million a year.
