Audit exemption thresholds UK: What small companies need to know

Opening paragraphs

Understanding the audit exemption thresholds UK is essential for small company directors who want to reduce compliance costs without falling foul of the law. This guide explains how exemption works, which companies qualify, and practical steps to confirm and claim exemption for the tax year 2026/27.

How audit exemption works for small companies

UK company law allows many small private companies to be exempt from a statutory audit. The basic idea is that companies below certain size tests do not need to commission an independent statutory audit of their annual accounts. This reduces cost and administrative burden for small businesses.

Audit exemption is not automatic. Directors must confirm the company met the qualifying conditions for the relevant accounting period and include the required statements in the statutory accounts. There are also situations where exemption is not available even if a company is small – for example, public companies and certain other types of companies cannot claim the exemption.

The three size criteria – how they work in practice

Most qualifying rules are based on three standard size criteria. A company will normally be treated as "small" for audit exemption purposes if it meets at least two of these three criteria for the financial year:

  • Turnover
  • Balance sheet total
  • Average number of employees

These criteria are applied to the company’s annual accounts prepared under UK accounting standards. Small company status for audit exemption is assessed at company level each accounting period. If a company exceeds the tests it will generally lose the exemption and an audit will be required for that period.

Turnover

Turnover refers to the total income generated from the company’s principal activities, reported in the profit and loss account. Directors should use their statutory accounts to determine turnover for the period.

Balance sheet total

The balance sheet total is the aggregate value of assets shown on the balance sheet. It is calculated according to the measurement rules in the applicable accounting framework.

Average number of employees

This is the average number of full‑time equivalent employees during the accounting period. Directors should count both full-time and part-time workers using the standard FTE calculation.

Important exclusions and special cases

Not every small company can use the audit exemption. Directors must be aware of exclusions and special circumstances that prevent claiming exemption.

  • Public companies cannot claim audit exemption.
  • Companies in regulated sectors may face different audit requirements from their regulator.
  • Certain companies, such as credit institutions or insurance companies, are subject to statutory audit regardless of size.
  • Companies that are part of larger groups may need consolidated accounts; group rules can affect audit obligations.
  • Shareholders with specific rights to require an audit may force one even if the company qualifies for exemption.

Charities and companies with charitable status have different accounting and audit tests in many cases. If you operate as, or with, a charity, check the Charity Commission and GOV.UK guidance for charity accounts and audit requirements: https://www.gov.uk/government/publications/charity-accounts

When is an audit required despite small size?

There are common situations where a small company still needs an audit. Directors should check these before deciding not to appoint an auditor.

  • If the company is required by company law because it is not eligible for exemption.
  • If the company’s articles, a loan covenant, or investor agreements require an audit.
  • If shareholder(s) meeting the statutory threshold request an audit.
  • If the company is a parent needing to produce audited consolidated accounts.

When in doubt, take professional advice. Missing an audit requirement can lead to regulatory problems, penalties, and loss of confidence from lenders or investors.

Micro‑entities and dormant companies – simpler routes

Some very small companies may qualify as micro‑entities. Micro‑entity accounts follow a simplified accounting regime that also interacts with audit obligations. Dormant companies that have had no accounting transactions are often exempt from audit and file dormant accounts instead.

Directors should check which accounting regime they are using when assessing audit needs. Different filing choices can change the content of accounts and the disclosure statements required to claim audit exemption.

How to claim the audit exemption correctly

Claiming exemption requires specific steps in the company’s statutory accounts and directors’ report. Small errors in wording or omission of the required statement can cause the exemption to be invalid.

  • Confirm the company met the small company tests for the accounting period.
  • Include the statutory audit exemption statement in the directors’ report and the balance sheet page where required by the accounting standard.
  • Make sure the accounts are prepared and filed in accordance with Companies House and applicable accounting standards.

Many companies use an accountant to review the accounts and confirm the exemption. An accountant can also help if the company needs to prepare a directors’ report that explains why audit exemption is claimed.

Practical checklist – are you eligible this year?

Use this checklist as a practical starting point when considering small company audit exemption:

  • Prepare draft statutory accounts for the relevant accounting period.
  • Calculate turnover, balance sheet total, and average number of employees under the applicable accounting rules.
  • Check whether the company is excluded from exemption due to its legal form, regulatory status, or shareholder agreements.
  • Confirm whether group accounts or consolidated reporting applies.
  • Decide whether stakeholders would still expect or require an audited set of accounts.
  • If eligible, include the exemption statement in the accounts and ensure correct filing with Companies House.

Common pitfalls directors should avoid

Directors regularly make a few avoidable mistakes when handling audit exemptions. Watch out for these pitfalls:

  • Relying on management accounts rather than statutory accounts for the size tests.
  • Failing to consider a group’s effect on audit obligations.
  • Missing investor, lender or article provisions that require audit.
  • Forgetting to include the required exemption wording in the statutory accounts.
  • Treating "small" informally for other regulatory purposes where different thresholds apply.

If you are uncertain about any of these points, get professional help early in the year so you can plan whether an audit will be needed when accounts are prepared.

When you might still choose an audit even if exempt

Some directors decide to commission an audit even when they qualify for exemption. Reasons include:

  • Providing assurance to banks, investors or customers.
  • Preparing for future growth or a potential sale where audited accounts add credibility.
  • Addressing complex transactions where independent verification helps board governance.

An audit can be a useful tool for governance and risk management. If cost is the main concern, consider a narrower independent review or assurance engagement as an alternative to a full statutory audit.

What happens if you need an auditor mid‑year?

If circumstances change during the accounting period, or if stakeholders request an audit before year end, directors should act promptly. Appointing an auditor and running an audit takes time and requires supporting documentation.

  • Contact prospective auditors early and discuss the likely scope.
  • Ensure your accounting records and supporting schedules are up to date.
  • Consider whether interim review work will be required to complete a timely audit.

Failing to appoint an auditor in time can delay filing or trigger regulatory follow‑up.

Group companies and subsidiaries – special considerations

Group structures complicate audit obligations. Even if an individual subsidiary is small, the group may exceed the thresholds and require consolidated audited accounts.

  • Check whether consolidated accounts are required for Companies House or by investors.
  • Understand how intra‑group eliminations and intercompany transactions affect balance sheet totals and turnover calculations.
  • Consider whether group reliefs or exemptions apply.

If you run a group, get specialist accounting advice to avoid unintended audit requirements.

Case studies – typical scenarios (illustrative)

Scenario 1 – A single‑director trading company

  • A small trading company prepares statutory accounts showing modest turnover and a small balance sheet.
  • It does not meet any regulatory exclusion and its articles do not require an audit.
  • The directors include the exemption statement and file accounts with Companies House without an audit.

Scenario 2 – Growing company with investor demands

  • A company qualifying for audit exemption signs new investment agreements that state audited accounts must be produced each year.
  • Although still small for statutory purposes, the company engages auditors to meet investor covenants.

Scenario 3 – Group parent and small subsidiaries

  • A parent company prepares consolidated accounts that exceed the small company thresholds.
  • The group must obtain audited consolidated accounts even though several subsidiaries are small and individually exempt.

These scenarios illustrate why eligibility must be checked against both legal thresholds and practical stakeholder requirements.

Practical steps for directors this accounting year

  • Early review – run the size tests on your draft statutory figures as soon as you prepare year‑end accounts.
  • Clarify stakeholder expectations – check lender, investor and contractual requirements before claiming exemption.
  • Document the decision – keep a signed minute or directors’ confirmation that the company met the exemption tests and explain any relevant judgments.
  • Use professional support – an accountant can prepare accounts and verify the exemption wording to avoid mistakes.
