Legislation Day 2025: What’s Changing?


On 21 July 2025, also known as ‘Legislation Day’, HM Treasury released a batch of draft laws and tax updates. These changes fall into three main areas: 

  1. Closing the tax gap

The government wants to reduce tax avoidance and make the system more accurate. Key proposals include: 

  • Requiring tax agents (people who deal with HMRC for others) to register with HMRC. 
  • Expanding Making Tax Digital for Income Tax, which is meant to cut down on errors. 
  1. Creating a fairer, more sustainable tax system

These proposals aim to rebalance who pays what, but some are controversial. They include: 

  • Reducing how much Inheritance Tax relief people can claim on farms and businesses from April 2026. 
  • Including inherited pension pots in a person’s estate for Inheritance Tax from April 2027. 
  • Treating Employee Car Ownership Schemes more like company cars for tax purposes. 
  1. Keeping the tax system up to date

The final batch of proposals focus on updates and clarifications: 

  • A change to help limit the rise in company car tax for plug-in hybrids (PHEVs) if new vehicle emissions standards (Euro 6e) are introduced. 
  • New guidance on PISCES – a planned private stock market that will let private companies trade their shares from time to time. The guidance covers how this might be taxed.
