1. What is a Micro-Entity Company?

A micro-entity is the smallest category of limited company in the UK. These companies benefit from simplified accounting and reporting requirements, making it easier and cheaper to comply with Companies House obligations.

According to the Companies Act 2006, micro-entities can prepare and file much simpler accounts than larger companies.

Key Benefit

Most sole-director limited companies with modest turnover qualify as micro-entities, allowing them to file a simple balance sheet instead of full accounts.

2. Eligibility Criteria for Micro-Entity Status

To qualify as a micro-entity, your company must meet at least 2 of these 3 criteriafor two consecutive financial years:

CriterionThreshold
Annual TurnoverNot more than £632,000
Balance Sheet Total (Total Assets)Not more than £316,000
Average Number of EmployeesNot more than 10

Important Note

Some companies cannot use micro-entity exemptions even if they meet the size criteria, including: public companies, companies that are part of a group, charities, and certain financial sector companies.

3. FRS 105 Accounting Standard

Micro-entities follow the FRS 105 (Financial Reporting Standard applicable to the Micro-entities Regime) accounting standard. This is the simplest UK accounting standard, designed specifically for the smallest companies.

Key Features of FRS 105:

  • Simplified balance sheet format with fewer disclosure requirements
  • No requirement to prepare a profit and loss account for Companies House
  • No requirement for a directors' report
  • No audit requirement (if you meet all criteria)

4. What You Need to File

As a micro-entity, you must file the following with Companies House:

Micro-Entity Accounts

  • • Abbreviated balance sheet
  • • Notes to the accounts (minimal)
  • • Balance sheet date statement

Confirmation Statement

  • • Annual confirmation of company details
  • • Due at least once every 12 months
  • • £13 online / £40 paper

Also Required for HMRC

You must also file a CT600 Corporation Tax Return with HMRC, along with full accounts and computations. This is separate from your Companies House filing.

Do I need an accountant to file micro-entity accounts?

What is the difference between annual accounts and CT600?

Annual accounts are filed with Companies House and show your company's financial position. The CT600 is your Corporation Tax return filed with HMRC, which calculates the tax your company owes. Both are required but filed separately.
