What Defines a Dormant Company Under UK Law?
A dormant company reports no significant accounting transactions, as defined in Section 1169 of the Companies Act 2006. It conducts only minimal activities like invoicing fees or maintaining bank accounts with no trades.
This status applies to limited companies with zero turnover. Examples include three common cases: startups awaiting launch, holding companies without subsidiaries, and shelved projects. Register as dormant via form AA02.
