Governments often introduce new laws to clamp down on tax avoidance, aiming to protect public revenue and ensure fairness. The latest legislation targeting rogue tax agents and tax avoidance schemes has raised concerns from the Chartered Institute of Taxation (CIOT). The CIOT warns that the new rules may fail to catch the real offenders and could unintentionally harm taxpayers who seek legitimate advice.

What the New Legislation Intends to Do


The government aims to tackle individuals and firms that promote or sell mass-marketed tax avoidance schemes. These schemes often promise unrealistic tax savings but can lead to serious penalties for taxpayers. The legislation seeks to:


  • Identify and restrict rogue tax agents who push these schemes.

  • Protect taxpayers from misleading advice.

  • Reduce the use of aggressive tax avoidance strategies.


The goal is to create a fairer tax system by removing bad actors who exploit loopholes or mislead clients.


Why CIOT Believes the Law May Miss Its Mark


The CIOT, a respected professional body for tax advisers, argues that the current proposals are not well targeted. Their main concerns include:


  • Scope of the Law: The legislation focuses on tax agents within the UK but misses many of the main offenders. According to HMRC, about 20 operators dominate the tax avoidance market, and most are not UK-based professionals but overseas entities.

  • Impact on Reputable Advisers: The new rules could impose strict and potentially unworkable conditions on legitimate tax advisers. This might discourage them from providing advice in complex cases or where tax liabilities are significant.

  • Unclear Legislation: Complex tax laws often require expert interpretation. If advisers fear penalties or restrictions, they may withdraw from advising clients, leaving taxpayers without proper guidance.


Ellen Milner, CIOT’s Director of Public Policy, highlighted that while the government’s intent is correct, the legislation as drafted will struggle to capture the real offenders who operate outside mainstream tax and accountancy professions.


The Risk to Taxpayers Seeking Advice


One unintended consequence of the new law could be that taxpayers find it harder to get reliable advice. This is especially true for individuals and businesses facing complicated tax situations. Without access to trusted advisers, taxpayers might:


  • Make mistakes in their tax returns.

  • Miss out on legitimate tax reliefs.

  • Face penalties due to incorrect filings.


The CIOT stresses that good advisers play a crucial role in helping taxpayers comply with the law. If these advisers withdraw from the market, the overall tax system could suffer.


Examples of Challenges Faced by Advisers


Consider a small business owner trying to understand new tax reliefs related to investment. The rules are complex and require professional advice. If advisers are restricted or fear legal repercussions, the business owner might:


  • Attempt to navigate the rules alone and make errors.

  • Avoid claiming reliefs they are entitled to.

  • Become vulnerable to aggressive schemes sold by unregulated operators.


This scenario illustrates how the legislation might backfire by pushing taxpayers toward riskier options or non-compliance.


What Could Improve the Legislation


The CIOT suggests several ways to make the law more effective and fair:


  • Better Targeting: Focus on the small group of overseas operators dominating tax avoidance schemes rather than broad restrictions on all tax agents.

  • Clearer Rules: Simplify the legislation to reduce uncertainty for advisers and taxpayers.

  • Support for Advisers: Provide guidance and protections for legitimate advisers to encourage compliance and good advice.

  • Stronger Enforcement: Use existing powers to go after rogue operators more effectively.


These changes could help protect taxpayers while still cracking down on those who abuse the system.


The Bigger Picture for Tax Compliance


Tax avoidance remains a challenge worldwide. Governments must balance cracking down on abuse with supporting taxpayers who want to comply. Laws that are too broad or unclear risk harming honest taxpayers and advisers. The CIOT’s warning highlights the need for careful design and consultation in tax policy.


Tax advisers are essential partners in the tax system. They help interpret complex rules and ensure taxpayers meet their obligations. Protecting their ability to operate fairly benefits everyone.



The new tax avoidance law aims to stop rogue agents and schemes but risks missing the real offenders and making it harder for taxpayers to get good advice. The CIOT calls for better targeting and clearer rules to protect both taxpayers and advisers. For anyone navigating tax matters, staying informed about these changes and seeking trusted advice remains crucial. If you are concerned about how this legislation might affect you or your business, consulting a qualified tax professional is a wise next step.
