Company Reporting in the United Kingdom

The reporting system for legal entities registered in the United Kingdom includes tax reports to HMRC (His Majesty’s Revenue and Customs), confirmation statements, and financial reports prepared in accordance with UK GAAP or IFRS standards submitted to Companies House. Reporting is a key element of corporate transparency, legal compliance, obligations to government authorities and the public, as well as a tool for building investor trust, which is critical under conditions of growing competition and economic instability.

At the same time, regulatory requirements and audit standards for reporting have become stricter after Brexit and the COVID-19 pandemic. They have been adapted to global challenges, including ESG principles and digitalization — particularly the use of the Making Tax Digital (MTD) platform. Increased control over transfer pricing and corporate tax necessitates accurate calculations, and audit — which is mandatory for medium and large enterprises — has become more rigorous.

It is advisable to entrust company reporting in the United Kingdom to professionals, as non-compliance with requirements or deadlines, as well as errors, may lead to significant fines, bank account freezes, reputational damage, forced company liquidation, and liability for management. If you own a company in the United Kingdom, AA Lawrange is ready to offer its assistance. Our services cover all matters related to reporting so you can focus entirely on growing your business.

What Reports Are Companies in the UK Required to Submit?

According to the Companies Act 2006, all business entities are required to report their activities. This applies to both active and dormant companies. However, the requirements and scope of reporting vary depending on the size and type of the enterprise. Reporting can be conditionally divided into three types:

1. audited reporting (verified by an independent auditor and confirmed with their opinion);
2. unaudited reporting;
3. dormant Company Accounts (DCA).

To fully comply with the strict requirements of regulators and supervisory authorities, demonstrate transparency, and also minimize the risk of sanctions, a company registered in the United Kingdom should preferably enlist the support of a reliable legal partner. In particular, the legal services of a law firm in the United Kingdom, as offered by AA Lawrange, make it possible to handle reporting tasks and more.

Below, we will detail the main types of reports submitted by companies in the UK. Please note that this list is not exhaustive. If the company has employees, it must also submit employer declarations (PAYE) to HMRC, including real-time information (RTI) as part of the payroll system. If employees receive “benefits in kind” (e.g. company car or interest-free loan), a P11D report is submitted; if they are offered options – an ERS report. If the company owns residential property, an ATED declaration is submitted under certain conditions.

Statutory Financial Reporting (Statutory Accounts)

This refers to a set of financial reports providing an overview of a company’s financial results for a specific period (usually 12 months), prepared based on the company’s accounting records and submitted:

• to the Companies House – within 9 months after the end of the financial year for private companies and within 6 months for public companies;
• to the UK tax authority (HMRC) – within 12 months after the end of the financial year.

The set of reports includes:

• the company’s balance sheet, showing the value of everything the company owns, owes, and is owed as of the last day of the financial year;
• the profit and loss account, reflecting the company’s sales, current expenses, and the profit or loss received for the financial year;
• the cash flow statement;
• the director’s report (if the company is not a micro-entity);
• notes with explanations of the figures;
• optionally – the auditor’s opinion (required depending on the size of the company).

Note! Copies of statutory accounts must be distributed to all shareholders and persons entitled to participate in the company’s general meetings.

Financial Reporting Standards: UK GAAP and IFRS

According to the Companies Act 2006, all UK businesses must prepare their financial reports in accordance with accounting standards established by the UK Generally Accepted Accounting Principles (UK GAAP) or the International Financial Reporting Standards (IFRS). UK GAAP defines the standards for legal entities in the United Kingdom, while IFRS is a globally recognized framework.

Important! The choice of standard under which company reports are submitted in the UK depends on the size of the enterprise, capital structure, and strategy. National UK GAAP standards are adapted for small and medium-sized businesses, while IFRS standards are mandatory for public companies and entities that are part of groups with an international presence.

There are differences between the standards – for example, in the rules on revenue recognition, leasing, and financial instruments, as well as in disclosure requirements: IFRS requires broader information disclosure compared to UK GAAP.

Full Financial Reporting: Composition and Features

There are different sets of reporting: full and abridged. Full financial reports are submitted by medium and large active enterprises.

Classification of UK companies (Thresholds valid until 6 April 2025 and for periods starting from 6 April 2025):

The composition of full financial statements includes:

• a detailed balance sheet with assets, liabilities, and equity;
• a profit and loss account;
• a statement of changes in equity;
• a cash flow statement;
• a directors’ report;
• notes disclosing accounting policies, risks, and obligations.

Note! Large companies (with turnover from £36 million, assets from £18 million, and 250 or more employees) are required to include a strategic report and ESG factor disclosures in their financial statements.

Abridged Financial Reporting for Small Companies

Three groups of entities are entitled to submit abridged accounts:

1. small enterprises (with turnover up to £10.2 million, balance sheet total up to £5.1 million, and up to 50 employees);
2. micro-entities (with turnover up to £632,000, balance sheet total up to £316,000, and up to 10 employees);
3. dormant companies.

Abridged financial statements of English companies include:

• a simplified balance sheet;
• a brief profit and loss account;
• a limited set of notes.

Important! Companies eligible to submit abridged accounts are also exempt from audit if they meet two of the following thresholds (thresholds valid for financial periods up to 6 April 2025 and starting after 6 April 2025):

1. annual turnover not exceeding £10.2 million / £15 million;
2. assets not exceeding £5.1 million / £7.5 million;
3. no more than 50 employees on average.

Company Tax Return

Alongside financial statements, a company must file a tax return (CT600) with HMRC. The data in this return must correspond to the statutory accounts. The tax return must be submitted within 12 months after the end of the accounting year, but if corporation tax is payable, it must be paid within 9 months and 1 day after the end of the accounting period.

The return includes:

• calculation of taxable profit;
• corporation tax (CIT) payable;
• reliefs (e.g. Patent Box or R&D Tax Relief).

The corporation tax rate depends on the company’s income:

• 25% for companies with income over £250,000;
• 19% for companies with income under £50,000;
• a marginal rate applies to companies with income between £50,000 and £250,000.

Value Added Tax (VAT)

The standard VAT rate is 20%. For companies with turnover over £90,000, VAT reporting in England must be carried out through the Making Tax Digital (MTD) system. First, the company must register as a VAT payer in the MTD system and then submit quarterly VAT returns.

This means that businesses must use accounting software that is compatible with and authorised by HMRC to manage their VAT records and submit tax returns.

A VAT return includes:

• VAT amounts payable or refundable;
• details of all taxable transactions.

Note! Small businesses may be eligible for simplified accounting schemes (Flat Rate Scheme), but prior approval from HMRC is required. A company can join the scheme if its VAT turnover is £150,000 or less. Under the scheme, the company pays a fixed VAT rate to HMRC, retains the difference between what it charges customers and what it pays HMRC, and cannot reclaim VAT on purchases – except for certain capital assets worth over £2,000.

Companies may also be required to submit additional VAT reports:

• EC Sales List – for businesses supplying goods/services to EU countries;
• Intrastat – for companies importing goods worth over £500,000 from the EU into Northern Ireland or exporting goods worth over £250,000 to the EU from Northern Ireland.

Confirmation Statement – Confirmation of Company Details

All companies, including dormant ones, must file a confirmation of the accuracy of their data with Companies House at least once a year. The form must be submitted within 14 days from the anniversary of the company’s incorporation.

The Confirmation Statement is filed electronically via the Companies House WebFiling system and includes the following information:

• details of directors and secretaries;
• registered office address;
• share capital structure;
• SIC codes (types of business activity);
• information about Persons with Significant Control (PSC).

Zero Reporting for Dormant Companies

Companies in the UK that do not carry out any business activity may be considered dormant and are exempt from submitting full financial statements. This status is granted if:

• there are no significant transactions during the financial year (other than payment of filing fees, penalties, or minimal administrative costs);
• the company is not part of a group that requires consolidated reporting.

The Dormant Company Account (DCA), also known as form AA02, is a simplified form of financial reporting that includes only a balance sheet showing share capital and reserves. A company tax return (CT600) is filed with HMRC with a note of dormancy, which exempts the company from paying corporation tax – this is referred to as a “zero” return. Dormant companies are not required to undergo an audit, even if they technically meet the criteria of a large enterprise.

Note! A business in the UK may become dormant for various reasons, such as holding property or intellectual property, reserving a company name for future use, undergoing reorganisation or restructuring, or temporarily suspending trading.

Reporting Requirements for Dormant UK Companies

“Zero” reporting is submitted to Companies House within 9 months after the end of the financial year. Such financial statements are submitted in England to confirm that no significant business activity took place during the year. Preparing annual reports for dormant companies is simpler than for active enterprises, but it remains a mandatory requirement. In addition, to maintain the status, the Confirmation Statement must be updated annually.

Important! If the company resumes its activity, it is obliged to notify the regulators and submit full financial statements for the relevant period. Failure to do so (for example, concealing operations) entails liability in the form of sanctions and the risk of compulsory liquidation.

Financial Reporting Standards for UK Companies

UK GAAP (Generally Accepted Accounting Practice) standards ensure transparency, comparability, and reliability of the data submitted by companies to regulators and supervisory authorities. The UK GAAP approaches apply to businesses of all sizes, from small firms to large corporations.

Financial Reporting Standards (FRS) are adapted to the needs of different categories of businesses, namely:

• FRS 100 defines the general principles for applying financial reporting standards. It establishes the criteria for selecting the appropriate reporting framework depending on the size, nature, and economic complexity of the organisation (for example, whether it is part of a group).
• FRS 101 is applied by subsidiaries of groups reporting under IFRS, provided that their parent company prepares consolidated accounts in accordance with IFRS. This reduces administrative burden while maintaining compliance with global standards.
• FRS 102 is the main standard for most UK companies, covering the accounting of assets, liabilities, income and expenses, disclosure requirements, including revenue recognition, financial instruments, lease accounting, and employee benefits. FRS 102 contains special provisions for small and medium-sized enterprises.
• FRS 105 is designed for micro-entities – companies with a turnover of up to £632,000, assets up to £316,000, and up to 10 employees. The standard significantly simplifies reporting by reducing the volume of disclosed information, making it ideal for small businesses.

What Company Owners Need to Know About Financial Reporting in the UK

Companies are required to prepare financial statements annually, including a balance sheet, profit and loss account, notes, and (for groups) consolidated accounts. The documents must comply with UK GAAP standards (FRS 102, FRS 105, etc.) or IFRS if the company is part of an international group. Alongside the financial statements, companies must submit a Corporation Tax Return to HMRC.

Financial reporting and auditing of companies in England are directly related to the scale of business activity. A mandatory audit is conducted if the company fails to meet two of the three small company criteria: turnover ≤ £10.2 million, assets ≤ £5.1 million, and number of employees ≤ 50. However, an audit is required regardless of size if the company is public, operates in a regulated sector (e.g., finance), or is part of a group not eligible for exemptions.

Despite all nuances, tax optimization in the UK is a manageable task if handled by professionals. Specialists at AA Lawrange can help you better understand the country’s taxation system and ensure tax efficiency of the business while strictly complying with legal requirements.

Reporting Deadlines and Penalties

A private company or limited liability partnership (LLP) has nine months after the end of the reporting period to file accounts with Companies House; a public company has six months. The deadline for submitting the tax return to HMRC is 12 months after the end of the accounting period it covers. Meanwhile, the corporate tax payment deadline is nine months and one day after the end of the accounting period. Missing these deadlines leads to penalties and an increased risk of inspections.

Penalties for Late Filing of Accounts at Companies House

Penalties for late filing of tax returns

• 1 day late – automatic penalty of £100;
• 3 months late – an additional £100;
• 6 months late – +10% of the estimated tax bill;
• 12 months late – another +10% of the estimated tax bill.

Note! If a taxpayer files the tax return late three times in a row, the £100 penalties increase to £500 each time.
