The rules are changing: are you ready to report your P&L?

From 2028, small and micro businesses will need to report their profit and loss.

For the UK’s network of small and micro businesses, filing annual accounts is about to go through a big change. The filing process has traditionally been a relatively streamlined, minimal disclosure exercise. Under long-standing rules, smaller corporate entities could take advantage of “filleted” or abridged accounts, allowing them to submit a basic balance sheet while keeping more granular financial data private.

But the regulatory landscape is about to change. Following the formal finalisation of measures set out under the Economic Crime and Corporate Transparency Act 2023, Companies House has confirmed a major overhaul of its corporate reporting rules. From April 2028, every single small business and micro-entity in the UK will be legally required to file a full profit and loss account.

This historic transition is designed to modernise the UK’s corporate register, improve financial transparency and clamp down on economic crime. These new mandates will fundamentally change how you prepare, package and submit your annual figures to Companies House, so understanding these changes early will ensure your business remains compliant without administrative friction.

What is a profit and loss statement?

Profit and loss may also be referred to as P&L or an income statement. It is a fundamental financial document that summarises a business’s revenues, costs and expenses incurred during a specific accounting period.

Unlike a balance sheet, which provides a static snapshot of what a business owns and owes at a single point in time, a P&L statement tells the dynamic story of a company’s operational efficiency over the course of a financial year. It details:

• Gross Turnover: Total sales revenue generated before any deductions.
• Cost of Sales (COGS): Direct costs tied strictly to production or service delivery (e.g., raw materials, direct labour).
• Gross Profit: Turnover minus the direct cost of sales.
• Operating Expenses/Overheads: Indirect operational costs, such as rent, marketing, utilities and administrative salaries.
• Net Profit: The definitive bottom line showing exactly how much actual profit (or loss) the business generated after factoring in all expenditures, interest and taxes.

Historically, micro-entities and small businesses were allowed to completely omit this statement from their public filings to avoid giving competitors insight into their profit margins and cost structures. From April 2028, this omission will no longer be an option.

What else is changing for businesses in 2028?

The introduction of mandatory P&L reporting is just one pillar of a much wider corporate reporting modernisation package. When the April 2028 deadline hits, several long-established accounting shortcuts will disappear simultaneously.

File annual accounts with commercial software, instead of paper or web

The days of logging into the free Companies House WebFiling portal to type in a few balance sheet figures by hand are ending. From April 2028, Companies House is closing its web-based and paper-based accounts filing routes entirely.

Every UK company, including dormant entities, must submit their annual accounts using commercial accounting software. These submissions must be delivered in an iXBRL (Inline eXtensible Business Reporting Language) format, which automatically applies digital data tags to your financial figures so regulatory systems can scan and analyse the information instantly.

Accounts and reports must be filed together in full

Under the current rules, companies sometimes file different components of their corporate reports piecemeal or exploit timing gaps. The 2028 reforms introduce a strict “single package” requirement. All components of your company’s required financial submission must be bundled and submitted electronically as a single, concurrent package.

Abridged accounts are discontinued

Small companies will no longer have the legal option to prepare or file “abridged” accounts. Abridged accounts allowed smaller firms to combine certain line items on the balance sheet and profit and loss accounts to simplify disclosures. From April 2028 onwards, the financial reporting framework will demand full standard line item breakdowns appropriate to your business size category.

Stronger eligibility statements will be required when claiming an audit exemption

If your small or micro business claims an exemption from having its accounts formally audited, as the vast majority of UK small businesses legally do, your directors will face greater accountability. The new regulations dictate that directors must provide a strengthened, explicit eligibility statement directly on the balance sheet, confirming precisely under which legislative criteria the company qualifies for the exemption.

You won’t be able to shorten your accounting referencing period as often

Some businesses historically shortened or extended their accounting reference periods (their financial year-end dates) repeatedly to align with tax advantages or delay filing deadlines. To curb practices that obscure timely financial tracking, Companies House will strictly limit how frequently a company can shorten its accounting period. Businesses will be required to provide an explicit, legitimate business justification if they attempt to shorten their period more than once within a rolling five-year window.

What will be the impact on businesses?

The transition to software-only filing and mandatory P&L reporting has triggered significant debate among business groups, with organisations like the Federation of Small Businesses (FSB) warning that it could introduce additional administrative burdens and operational costs. The government has, however, introduced a crucial compromise to protect commercial privacy.

The Privacy Compromise: The Publication Opt-Out

To address widespread fears that publishing sensitive cost data could harm small businesses or expose them to predatory pricing from larger competitors, GOV.UK has confirmed an opt-out mechanism.

While small and micro businesses must file their P&L statements with Companies House, they can actively choose to withhold the P&L from the public register. This creates a “frosted glass” effect:

Who sees your data? Companies House, HMRC and law enforcement agencies will have full access to your P&L to verify compliance and fight fraud.

Who doesn’t see your data? The general public, your customers, your neighbours and your direct competitors will not see your P&L on the public register if you choose to opt out.

Higher Digital Adjacency & Efficiency

For businesses that still rely on manual spreadsheets, paper records or basic text documents to manage their annual bookkeeping, the 2028 deadline presents a mandatory call to action. You will need to transition to a modern cloud accounting platform capable of generating and transmitting tagged iXBRL financial files.

While this involves an adjustment period and potential subscription costs, the long-term benefits of digital accounting are substantial. Automated software dramatically reduces human entry errors, simplifies VAT tracking and gives founders real-time visibility into their cash flow rather than leaving them to decipher their financial health months after the year has ended.
