Micro-Entity vs Small Company Accounts

Choosing the right accounts regime is one of the first decisions a director faces at year end. UK company law sets out several size regimes, and the two smallest, the micro-entity regime and the small company regime, each come with their own accounting standard, disclosure requirements and filing options. Picking the wrong one can mean preparing more detailed accounts than the law requires, or missing out on simplifications that save time and money. This guide explains the thresholds, the differences between FRS 105 and FRS 102 Section 1A, and how to decide which suits your business.

Size thresholds explained

A company’s size is determined by three measures: annual turnover, balance sheet total (gross assets) and average number of employees. To fall within a regime, a company must not exceed two of the three relevant limits. The micro-entity limits are the lowest, followed by the small company limits.

A company generally needs to meet the conditions for two consecutive years before the classification takes effect, and the same two-year rule applies when moving up or down between regimes. Because the precise figures are reviewed periodically, always confirm the current thresholds published by Companies House and HMRC before you finalise your classification.

Micro-entity criteria

A micro-entity is the smallest category of company under UK GAAP. To qualify, a company must satisfy at least two of the three micro-entity conditions (the lowest turnover, balance sheet and employee limits). Many one-person and owner-managed limited companies fall comfortably within these limits.

Some entities are excluded from the micro-entity regime regardless of size, including charities, certain financial and insurance undertakings, and companies that prepare group accounts. If your company is part of a group or carries out a regulated activity, check the exclusions carefully before assuming you qualify.

FRS 105 features and limits

Micro-entities report under FRS 105, the financial reporting standard designed specifically for the smallest companies. Its defining feature is simplicity:

• Highly abbreviated balance sheet and profit and loss account with prescribed minimum formats.
• Very few notes to the accounts.
• No requirement to prepare a directors’ report for filing in the usual detailed way.
• Accounts are presumed to give a true and fair view if they comply with the legal minimum, so fewer judgements are needed.

FRS 105 also imposes limits. It does not permit revaluation of assets or fair value accounting, so investment property and financial instruments are held at cost. Deferred tax is not recognised. These restrictions keep the accounts simple but can make them less informative for lenders or investors who want a fuller picture. For the broader framework, see our overview of accounting principles .

Small company criteria and FRS 102 Section 1A

A small company sits a step above a micro-entity. It qualifies by meeting at least two of the three small company limits, which are higher than the micro-entity limits but below the medium-sized threshold. A company that grows beyond the micro limits will typically move into the small company regime.

Small companies usually report under FRS 102, applying the reduced disclosure framework in Section 1A. This keeps the recognition and measurement rules of full FRS 102 while cutting back the volume of disclosures required. Unlike FRS 105, FRS 102 allows options such as revaluing property and recognising deferred tax, giving a more complete view of the company’s position.

Disclosure differences

The clearest practical distinction between the two regimes is the level of disclosure.

• Micro-entity (FRS 105): minimal notes, with only a handful of statutory disclosures such as advances to directors and certain commitments.
• Small company (FRS 102 Section 1A): more extensive notes covering accounting policies, related party transactions and other matters needed for a true and fair view.

Small company accounts therefore take longer to prepare but tell a richer story, which can matter when you apply for finance or bring in new shareholders.

Filing options

Both regimes allow simplified filing with Companies House, though the rules have been tightening. Historically, micro-entities and small companies could file reduced or “filleted” accounts, often omitting the profit and loss account from the public record. You should confirm the latest filing requirements before submission, as the options available to small entities have been changing. Our guide to filing accounts with Companies House walks through the process and deadlines.

Whichever regime applies, a full set of accounts must still be prepared for the members and for your Corporation Tax return to HMRC. See preparing statutory accounts for what a complete set involves.

Pros and cons of each

The micro-entity regime wins on cost and speed; the small company regime wins on transparency and flexibility.

How to decide

Work through these questions in order:

1. Do you qualify? Confirm you meet at least two of the relevant size limits and are not excluded.
2. Who reads your accounts? If banks, investors or grant providers rely on them, the fuller FRS 102 disclosures may be worth the extra effort.
3. Do you need accounting options FRS 105 lacks? Revaluing property or recognising deferred tax requires FRS 102.
4. What is your growth trajectory? If you expect to outgrow the micro limits soon, adopting FRS 102 early can avoid a future transition.

A genuinely tiny, owner-managed company with no external finance often benefits from FRS 105. A small company with lenders, investors or property on the balance sheet is usually better served by FRS 102 Section 1A. When in doubt, model both and weigh the savings against the value of clearer accounts. Good software keeps your underlying records ready for either route, so see ReAI accounting software for how digital records support year-end reporting.
