Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what assessment she has made of the efficacy of the Government's efforts to reduce tax evasion.

This question was answered on 22nd December 2025

HMRC is committed to closing the tax gap further and tackling non-compliant behaviours such as tax evasion, tax avoidance, criminal attacks, error, failure to take reasonable care, hidden economy activity, legal interpretation issues, and non-payment.

In 2024 to 2025, HMRC’s compliance work contributed to record tax revenues of £875.9 billion, collecting and protecting £48 billion of tax that would have gone unpaid if HMRC hadn’t stepped in – up from £41.8 billion the previous year.

At the Autumn Budget 2025, the government announced a package of measures that will raise a further £2.4 billion in additional tax revenues in 2029 to 2030. This builds on announcements at Autumn Budget 2024 (£6.5 billion), and Spring Statement 2025 (over £1 billion) and brings the total revenue from closing the tax gap announced this Parliament to £10 billion in 2029 to 2030.
