HM Revenue & Customs (HMRC) has rolled out a new online tool to help taxpayers make sense of compliance checks. The tool, first launched in April 2025 and updated in September, is designed to walk you through each stage of a check and make it easier to access support when you need it.

So, what is a compliance check? 

Simply put, it’s when HMRC reviews your tax position to make sure you’ve paid the right amount, claimed the correct allowances and reliefs, and that the tax system is operating fairly. 

During a check, HMRC might send you a letter asking for information, have discussions with you to clarify your tax position, and then work out the correct amount you owe before closing the review.

Want support if HMRC comes knocking?

For business owners or contractors who want extra peace of mind during an HMRC compliance check, Crunch Protect offers practical support and protection. It can help cover accountancy fees, guide you through the process, and ensure you respond to HMRC correctly, reducing stress and avoiding costly mistakes. 

Used with HMRC’s new online tool, you get the best of both worlds: clear guidance from HMRC and hands-on support from our experts. Together they give you a simple, step-by-step approach to managing enquiries so you can stay focused on running your business with confidence.

What can you find in HMRC’s interactive compliance check tool?

The new tool is packed with guidance on key areas, including:

• Why HMRC is asking for certain information
  
• How to request extra support if you need it
  
• Appointing an agent to act on your behalf
  
• Disagreeing with HMRC’s calculations
  
• How to pay any assessments or penalties
  
  

Accessible support at every stage

The tool is available in English and Welsh, and HMRC encourages taxpayers to use it throughout the check to get the guidance and support they need.

And if you ever want help understanding how HMRC’s guidance applies to your business, our team at Crunch is always here to help.
