What Are Micro-Entity Accounts?

Micro Entity Accounts in the UK are simplified financial statements for the smallest limited companies. This allows the qualifying companies to file significantly less information with Companies House. This helps save time and increase financial privacy, provided the company meets two out of three of the following requirements.
  • An annual turnover of £1 million or less.
  • A balance sheet total of £500,000 or less.
  • An average of 10 or fewer employees.

Why File Micro-Entity Accounts?

Filing micro entity accounts is required for the following reasons:

  • Reduced Reporting

You will only file a simplified balance sheet and notes publicly. You will not file a full profit/loss account or directors’ report. This will save you time and money.

  • Simplified Standards

The accounts must follow the more straightforward FRS 105 standard. It requires less specialised knowledge.

  • Cost Savings

Avoiding extensive disclosures and detailed reporting can reduce accounting fees.

  • Compliance

Ensure filing with Companies House for public record and HMRC for tax purposes.

How to File Micro Entity Accounts?

Filing micro entity accounts involves the following steps:

  • Check Eligibility and Prepare Accounts
