Filing & Compliance Basics

All UK limited companies must prepare and file annual accounts to stay legally compliant. Annual accounts are statutory records that summarise a company’s financial position at year-end. Company accounts UK are financial statements, typically including a balance sheet, profit and loss account, and notes. Example: a small limited company may file abridged accounts or micro-entity accounts to simplify disclosure.

Fact: Directors must file accounts within nine months of the company’s year-end, or face penalties starting at £150 for late filing.

Dormant Companies Definition and Filing

Dormant companies file simpler accounts when they have had no ‘significant’ accounting transactions. Companies House treats a company as dormant if only permitted transactions occur, such as paying filing fees or receiving nominal share capital.

A dormant company has no significant trading activity during the accounting period. Example: a newly incorporated company that hasn’t traded yet or a business on hold.

Tip: Dormant companies still need an annual confirmation statement and may still need to inform HMRC if they were ever registered for Corporation Tax.
