Companies House filing reforms: why the need to comply is an opportunity to help your business thrive

July 16, 2026
Companies House accounts reforms under the Economic Crime and Corporate Transparency Act 2023 (ECCT Act 2023) are coming into effect from 1 April 2028. All small and micro limited companies in the UK – including personal service companies – need to take action. This is particularly relevant if your business meets the small company thresholds.

Small Company Thresholds: 

  • Turnover of no more than £15 million.
  • Balance sheet total of no more than £7.5 million.
  • 50 employees or less.

 

What’s changing? 

  • Companies House filings will need to be done using third party commercial software (in iXBRL format) – this has implications for those who still rely on WebFiling, paper filing, or manual year-end processes for dormant or small subsidiaries etc. 
  • All companies will need to file a profit & loss statement as well as a balance sheet. (although some can opt out of their P&L being filed publicly). They are expected to have the option to opt out of publication of that profit and loss information on the public register, but the detailed opt-out process has not yet been confirmed. The aim of this is to ensure records a company files with Companies House and HMRC align more closely. 
  • The option to file abridged accounts is being removed. This supports the drive for consistency in company information but may be a concern if financial information that is publicly available could be sensitive. 
  • Audit exemption declarations will need to be strengthened. The rules here can be complex – you’ll need to prepare an enhanced statement and be sure all the conditions are met. 
  • The number of times you can shorten your accounting period is being limited. A company will have to provide a business reason if they want to shorten the period more than once within 5 years. This means timing decisions should be considered carefully. 

 

How would acting now benefit my business? 

Many small business owners may not realise what the changes mean for their business – it is easy to assume your accountant will handle it. For others managing company secretarial and governance work as part of a wider role, capacity may also be limited. 

For many companies, this will be easy to push down the priority list – but acting early makes transition smoother – and planning now can add real value to your business. 

It will: 

✔️ Improve accuracy and reliability of your financial data. 

✔️ Help you make better informed business decisions. 

✔️ Modernise processes to enhance efficiency. 

✔️ Help protect your business from errors, inconsistencies and financial crime. 

 

What steps should I be taking? 

  • Move to compliant software – you need to find the right one that best supports your business. 
  • Consider your eligibility for/desire to opt out of the public profit & loss filing register once the process is confirmed – Companies House and HMRC will still be able to see it. 
  • Check your accounting, tax and Companies House records are consistent, accurate and up to date. 
  • If you claim audit exemption, identify the specific exemption relied on and ensure you have supporting evidence for the enhanced directors’ statement. 
  • Speak with your accountant about tax planning, given the reducing flexibility around shortening accounting reference periods. 

 

Are there other regulatory changes I need to think about? 

Yes. The accounts reforms sit alongside a wider programme of Companies House and governance reform. Other changes include: 

  • director and person with significant control (PSC) verification checks are being phased in 
  • requirements for companies to maintain an appropriate registered office address and registered email address 
  • for companies applying the UK Corporate Governance Code, the Provision 29 material controls declaration framework
