- Mandatory software filing for company accounts begins 1 April 2027.
- The changes aim to increase transparency.
- Small companies will no longer be able to file abridged accounts.
- Some firms face new software costs.
It’s not just income tax that’s being made digital in the mid-2020s UK regulatory system. From 1 April 2027, new rules will require corporate accounts to be filed using commercial software.
The change is part of a program of reforms to modernise the register and improve transparency. It aims to cut fraud and economic crime, improve data quality, and boost accountability for reporting for businesses.
Modernising Companies House is widely thought to be a positive step. But adapting to so many new requirements in so short a time may prove challenging for small businesses and their accountants.
A push for transparency
The reforms are part of the Economic Crime and Corporate Transparency Act 2023 (ECCTA), which gives Companies House new powers to verify identities and challenge inaccurate information.
Those reforms will bolster data clarity by making it mandatory for all companies to file their annual accounts using software that tags the information in iXBRL (Inline eXtensible Business Reporting Language) format. While that format will sound complex to many; it actually allows the information to be readable by both humans and machines.
Companies claiming audit exemption will also need to provide an enhanced directors’ statement, and provide a valid business reason to shorten their accounting reference period.
The other key change for small companies is that they will no longer be able to prepare and file “abridged” accounts. They will now be required to file a copy of their balance sheet, directors’ report, auditor’s report (unless exempt), and profit-and-loss account.
The requirement for small businesses to file more comprehensive financial information is designed to make it easier for anyone with interest in the business – whether lender, customer, or (more controversially) competitor – to take the temperature of their financial performance.
Simon Kearsley, CEO of accountancy software provider bluQube, argues that such transparency underpins confidence – and confidence fuels economic growth.
“Trust and transparency are the cornerstones of a healthy economy.”

Gains from personal responsibility
Rules around confirmation statements will be tightened as part of the changes, increasing directors’ accountability for the accuracy of accounts and the use of audit exemption.
bluQube’s Kearsley says the changes are absolutely necessary. More personal responsibility on their shoulders may feel like an added administrative burden, he says, but it does raise standards across the board. He says it’s surprising how often people – even experienced finance professionals – understand the numbers but not the story behind them. When all businesses are reporting to the same standard, financial data becomes clearer and easier to interpret, not just for accountants, but for decision-makers who rely on that information.
He believes the changes will bring the UK a step closer to a more robust, data-driven regulatory environment. Transparency and accountability are essential in a digital-first economy where decisions are driven by data accuracy.
“For too long, limited checks have allowed inaccurate information to circulate, undermining trust in the system,” says Kearsley.
An accurate picture for stakeholders
Extra automation and validation are designed to improve the overall quality of small businesses’ accounts, helping external stakeholders assess the business with greater confidence.
Kearsley notes how he has seen first-hand how inconsistent reporting can distort perceptions. He recalls: “Years ago, we lost a deal because another company appeared financially stronger. They had a good deal of cash in the bank – but ten times that amount in accumulated losses propped up by borrowing.”
Standardised reporting helps prevent those kinds of misjudgements, ensuring comparisons are based on substance, not surface figures: “Trust and transparency are the cornerstones of a healthy economy,” he says.
Potential new costs for small business
A key implication of the new rules is the mandatory shift to commercial accounting software. Nicole Zalys is founder of accountancy firm Villiers & Co and a financial consultant at Money Squirrel. She says that those businesses not already using compliant software may face increased costs for subscriptions, setup and training.
Integrated digital tools can streamline bookkeeping, payroll and accounts production, saving time and reducing manual effort in the long run. For already stretched small businesses, she says, the additional cost could represent a challenge.
The first step in preparing for the reforms, says Zalys, is reviewing or researching accounting software that will meet the new Companies House requirements.
Preparation starts with good data management
For Kearsley, the sooner SMEs begin aligning their reporting practices with the new standards, the smoother the transition will be. “It’s about getting comfortable with transparency,” he says.
Businesses should review their records, ensure directors’ details are correct, and strengthen internal processes around compliance. Digital systems can make this easier by centralising and automating key reporting tasks, but ultimately it comes down to having accurate, consistent information across the organisation.
The real challenge now is ensuring the changes are enforced effectively and supported by the right technology and resources, says Kearsley. As he adds, “implementation will be the key test.”
