Tax policy changes are increasing the cost of the tax system for businesses and HMRC.
Conclusion
Tax policy changes are also increasing the cost of the tax system. Of the 240 changes announced over the period from 2022 to 2024, HMRC identified 16 changes as having a significant financial impact on businesses, of which 13 had estimated implementation and ongoing costs totalling £913 million. HMRC also estimated that changes would further increase its costs over the next few years by around £875 million through a mix of one–off and ongoing costs.10

HM Government
Accepted
1.1 The government agrees with the Committee’s recommendation. Target implementation date: Summer 2025 1.2 The government has committed to simplifying the tax system and taking this forward as part of its three strategic priorities for HMRC (improving day-to-day performance and the overall customer experience, closing the tax gap, and reform and modernisation). 1.3 In summer 2025, the government will publish HMRC’s Transformation Roadmap which will bring together HMRC’s strategic and transformation ambitions into a single, public document. The roadmap will set out how HMRC plans to transform and simplify the way it administers tax and customs to reduce the time customers spend managing their affairs through better digital services, simplifying tax rules and improving education and guidance. The Roadmap will include the metrics HMRC will use to report progress. 1.4 HMRC already publishes the cost for HMRC to collect each £1 of tax, within its Annual Report and Accounts, which has been stable at around half a penny since 2017-18. 1.5 HMRC publishes estimates of any significant change in administrative burden on businesses arising from changes in tax policy in Tax Information and Impact Notes. The estimates draw on insights and data from a range of sources, including evidence in HMRC’s Standard Cost Model (SCM), which contains data on the costs of existing obligations. HMRC is assessing the feasibility of updating the SCM to produce a publishable estimate of business taxpayers’ costs and is also considering measurement of administrative burdens on individual taxpayers.
