Dormant Limited Companies in the UK: Rules, tax implications and how to stay compliant

If you’re running a Limited Company in the UK, there might be times when you decide to stop trading, but don’t want to close your business entirely. Whether you’re taking a break, planning, or restructuring, making your company dormant can be a practical solution. 

But if you do decide to make your company dormant, it does come with rules. From Companies House filings to HMRC obligations, it’s important to understand exactly what’s required to stay compliant. 

In this blog, we explain what a dormant company is, when it makes sense to make your company dormant, and how to manage it efficiently and compliantly. 

• A dormant company will not have any significant accounting transactions during the financial year  

• A dormant company’s accounts can only be filed if the company has never traded  

• You are still required to file a confirmation statement annually  

• Informing HMRC may reduce filing requirements, but optional filings can be beneficial  

• Closing VAT and PAYE schemes can reduce admin and ongoing obligations  

A dormant Limited Company is one that has had no significant accounting transactions during its financial year. This will often apply to business owners who have paused trading, or for companies that have been set up in advance of future activity. 

This can be where directors easily get caught out. 

You’re only able to file dormant company accounts if your company has never traded since incorporation. If your company has traded at any point, even if it’s now inactive, you must continue filing full statutory accounts each year. 

You must also continue submitting an annual confirmation statement to confirm company details such as its directors, shareholders, and registered office address. 

One of our contractor clients paused trading due to a market slowdown but didn’t want to lose their company setup. 

By working with their Client Director, they: 

• Maintained full compliance with Companies House  

• Avoided unnecessary filings with HMRC  

• Kept the flexibility to restart trading quickly  

This approach meant they were ready to go again as soon as new opportunities arose. 

Depending on your business goals, dormancy can be a strategic decision. 

Some common reasons can include: 

• Taking a break from trading
  (e.g. maternity/paternity leave, sabbatical, or economic slowdown)  

• Protecting your company name
  Secure your brand or idea for future use. Trademarks are also recommended  

• Business restructuring
  Pause activity while reorganising or preparing for a sale  

• Avoiding dissolution
  Keep your company active legally without closing it permanently  

Dormancy allows you breathing space, without losing your business identity in the process.

HMRC Requirements 

You should inform HMRC as soon as possible when your company becomes dormant. You can do so by: 

• Updating your Corporation Tax account online  

• Writing to HMRC  

• Calling the Corporation Tax helpline  

HMRC may then issue an exemption from filing a Company Tax Return. 

However, you may still choose to file if: 

• You have allowable expenses creating a loss  

• You want to carry forward losses to offset future profits  

If your company is no longer trading, consider simplifying your obligations: 

• VAT: De-register to stop quarterly VAT returns  

• PAYE: Close your PAYE scheme if there are no employees (including directors)  

Dormant companies may still incur running costs, such as: 

• Accountancy fees  

• Bank charges  

• Registered office services  

• Software subscriptions  

If these are valid business expenses, they may create a loss that can be carried forward to offset future profits, and your client director will be able to assist with this. 

Making your company dormant can be a smart, flexible option, but only if it’s managed correctly. 

Understanding the difference between “non-trading” and “dormant” is key, especially when it comes to filing requirements and tax efficiency.
