State of Tax Administration 2025

The fourth of TaxWatch’s annual data deep-dives into the administration of the UK tax system, covering the 2024-25 tax year. Using published data and extensive figures obtained via Freedom of Information, we look at how HMRC’s progress in the last year compares with past performance; whether the deployment of its staff and resources matches the measured challenges of the tax system; and taxpayers’ experiences of tax administration.

Anyone can establish themselves as a tax adviser regardless of qualifications or competence. This report reviews problems created by the industry’s lack of regulation, examines regulatory practices in other countries, and recommends an independent regulatory body for the UK tax advisory industry.
