This helpsheet has been issued by ICAEW’s Technical Advisory Service to help members understand when a company qualifies as a micro-entity under the Companies Act 2006.

Members may also wish to refer to the following related helpsheets:

• Is a company or group small?
• Ineligible companies and groups
• Calculating employee numbers
• Small and micro company size calculator

When a company is assessing whether it is subject to the micro-entities regime, it must have regard to s384A and s384B of the Companies Act 2006. The micro-entities regime applies to a company for a financial year in which:

• The company qualifies as a micro-entity; and
• Is not excluded from the micro-entities regime.

Company size thresholds (for periods commencing on or before 5 April 2025)

To qualify as a micro-entity, in size, companies must be assessed against the thresholds in the table below.

Company size thresholds (for periods commencing on or after 6 April 2025)

First year of the company

If it is the first year of the company, it will qualify as micro under s384A of the Companies Act 2006 if it satisfies two or more of the thresholds in the above table.

Subsequent year(s) of the company

If it is not the first year of the company, a ‘two year rule’ applies by virtue of s384A(3) which states that in relation to a subsequent financial year (i.e. not the first year of the company), where on its balance sheet date a company meets or ceases to meet the qualifying conditions, that affects its qualification as a micro-entity only if it occurs in two consecutive financial years. As such a company may have to track back over several years of history to determine its size (the Small and micro company size calculator may be of assistance). Please refer to the “Transition to the new thresholds” section for further details on how the new thresholds should be applied.

Parent company

If the company is a parent company, in addition to meeting the above requirements, it will only be able to qualify as a micro-entity (per s384A(8) if the group headed by the company qualifies as a small group as determined by s383(2) to (7) (see Is a company or group small? helpsheet).

SI 2024/1303 amends section 384A of Companies Act 2006, enacting an increase in the size thresholds used to assess company and group size. The new thresholds have effect for financial years beginning on or after 6 April 2025 with a company looking to these thresholds going forwards and also in assessing the application of the two year rule for entities changing size.

Consider a company with a year end of 31 March.

The first year end where this company can look to the new thresholds is 31 March 2027 because the year to 31 March 2026 begins on 1 April 2025 meaning the year begins before the new thresholds take effect on 6 April 2025.

We can see that this entity has historically been a small company because it has consistently breached all three thresholds to qualify as micro. When we consider the company size for the year ended 31 March 2027 we apply the new thresholds to our previous years as well as the current year.

Under the new thresholds the company would have met the new conditions to qualify as micro if they had been in effect for the 2026 and 2025 year ends.

This means (subject to any considerations around ineligibility) the company would qualify as small for the March 2025 and March 2026 year ends but would qualify as micro for the year ended March 2027.

Even if a company meets the size criteria for qualification as a micro-entity, there are a number of exclusions from the micro entity regime (terms in bold are defined in the Glossary section at the end of this helpsheet).

Group accounts

If the entity is a parent entity which prepares group accounts, or is not a parent but its accounts are included in consolidated group accounts for that year, then it is not able to take advantage of the micro-entity provisions (Companies Act 2006 s384B).

Exclusions

Under the Companies Act 2006 s384B(1), the micro-entity provisions do not apply in relation to a company’s accounts for a particular financial year if the company was at any time within that year:

(a) a company excluded from the small companies regime by virtue of s384 (see Ineligible companies and groups helpsheet),
(b) an investment undertaking as defined in Article 2(14) of Directive 2013/34/EU of 26 June 2013 on the annual financial statements etc of certain types of undertakings,
(c) a financial holding undertaking as defined in Article 2(15) of that Directive,
(d) a credit institution within the meaning given by Article 4(1)(1) of Regulation (EU) No. 575/2013 of the European Parliament and of the Council, other than one listed in Article 2 of Directive 2013/36/EU of the European Parliament and of the Council on access to the activity of credit institutions and investment firms,
(e) an insurance undertaking as defined in Article 2(1) of Council Directive 91/674/EEC of 19 December 1991 on the annual accounts of insurance undertakings, or
(f) a charity.

Brexit

For periods commencing after the end of the transition period (31 December 2020) s384B(1) of the Companies Act 2006 is changed such that the micro-entity provisions do not apply in relation to a company’s accounts for a particular financial year if the company at any time within that year:

(a) was a company excluded from the small companies regime by virtue of s384 (see Ineligible companies and groups helpsheet),
(b) would have been an investment undertaking as defined in Article 2(14) of Directive 2013/34/EU of 26 June 2013 on the annual financial statements etc of certain types of undertakings were the United Kingdom a member State,
(c) would have been a financial holding undertaking as defined in Article 2(15) of that Directive were the United Kingdom a member State,
(d) a credit institution within the meaning given by Article 4(1)(1) of Regulation (EU) No. 575/2013 of the European Parliament and of the Council, which is a CRR firm within the meaning of Article 4(1)(2A) of that Regulation,
(e) would have been an insurance undertaking as defined in Article 2(1) of Council Directive 91/674/EEC of 19 December 1991 on the annual accounts of insurance undertakings were the United Kingdom a member State, or
(f) was a charity.

If the company qualifies as a micro-entity, unless there is anything specifically in the articles or other governing documents of the company, it is a choice of the directors (not the accountant) as to whether the micro-entity regime is applied.

The directors should, however, consider whether the accounts provide sufficient information to users of the accounts and whether the use of the micro-entity provisions may have an adverse impact on credit ratings or cause difficulties in providing the information required by lenders.
