LONDON — The UK government has unveiled a comprehensive package of reforms to how businesses file their annual accounts, giving millions of small businesses an extra year to prepare for the transition to a fully digital system.

The measures, which stem from the landmark Economic Crime and Corporate Transparency Act 2023 (ECCT Act), are now scheduled to come into effect in April 2028, shifting back from the originally anticipated April 2027 start date. Officials stated the delay is designed to give UK businesses a “buffer” of one full accounting year plus nine months to adapt to the new framework.

The Profit & Loss Compromise: Privacy vs. Transparency

At the heart of the announcement is a major compromise regarding small businesses and micro-entities. Under the new rules, these smaller companies will be required to submit profit and loss accounts to Companies House—bringing them in line with larger corporations.

However, following heavy pushback from the business and investment community over commercial privacy risks, the government will allow smaller companies to opt out of publishing this sensitive financial data on the public register.

While the general public may not see the profit and loss breakdown of a local business, the data will not be hidden from everyone. Companies House, HM Revenue and Customs (HMRC), and law enforcement agencies will retain full access to the filed documents to help cross-reference data and detect fraud, tax evasion, and economic crime.

For small firms looking to attract investors or secure bank loans, the option to keep their profit and loss statement public will remain available.

The Death of Paper and Web Filing

The 2028 rollout will officially mark the end of traditional filing methods. Companies House confirmed it will completely close its paper-based and manual web-filing systems for financial accounts.

Instead, every one of the UK’s registered companies—whether filing independently or through an accountant—must submit accounts via commercial software using the Inline eXtensible Business Reporting Language (iXBRL) format.

Government officials state that transitioning to software-only filing will significantly modernize the UK register, aligning it with international standards and making financial data much easier to aggregate, compare, and analyze.

Additional Key Changes At-A-Glance

The overhaul introduces several other tightening measures for corporate reporting:

• No More Abridged Accounts: The option for companies to file abridged (simplified) accounts is being entirely removed.
• Audit Exemptions Scrutinized: Companies claiming an audit exemption will face a much stricter and strengthened “eligibility statement” requirement.
• All-In-One Submissions: All component parts of a company’s accounts and reports must be submitted together as a single package.
• Accounting Period Restrictions: The government is capping the number of times a company can shorten its accounting reference period to prevent businesses from manipulating their filing deadlines.

While the web filing system is being shut down for financial accounts, Companies House clarified that its standard web portal will remain open and fully functional for non-accounting updates, such as filing annual confirmation statements or changing director details.

Companies House has announced it will begin proactively contacting business owners via their registered email addresses in the coming months to provide guidance and a pre-approved list of compliant software providers.
