Dormant doesn't mean done: the filings every inactive UK company still owes

A significant portion of Gulf-owned UK companies are dormant. The director registered the company — perhaps during COVID, perhaps in anticipation of a UK expansion, perhaps to hold a name or structure — and then the business never activated. Years pass. The company sits unused. And the director, reasonably but incorrectly, assumes that an inactive company needs nothing. It does.

Under UK company law, a company is dormant if it has had no significant accounting transactions during its financial year. Significant transactions exclude certain administrative entries like the original share capital, Companies House registration fees, and a narrow set of others. Beyond those, if nothing has moved through the company — no revenue, no expenses, no bank activity — it qualifies as dormant. But dormant status changes the cost and complexity of filings, not the obligation to file.

Every dormant UK company must file two things each year: dormant accounts (form AA02) with Companies House, and a confirmation statement. The dormant accounts are simple — they show a nil profit and loss and a basic balance sheet. They take minutes to prepare. The confirmation statement confirms the company's register details are current. Neither filing requires an active accountant to spend hours on your books. But both are legally required, both have deadlines, and both carry penalties for lateness.

The corporation tax position is cleaner for dormant companies — if you've told HMRC your company is dormant, they won't expect a CT600 for that period. The key phrase is 'if you've told them'. When your company became dormant, you should have notified HMRC. If you didn't — which is common — HMRC's default assumption is that the company is still active. That creates outstanding CT600 obligations you may not know about. Catching up on these is straightforward once identified, but it needs to be done.

The cost calculation is simple. Dormant company filing is the cheapest category of UK compliance work. The consequences of ignoring it are not cheap: £500 for a late confirmation statement, up to £1,500 per year for late accounts, and — if multiple years are missed — Companies House begins strike-off proceedings. A dissolved company loses its name. If there's any balance in the company's bank account on dissolution, those funds can become bona vacantia — owned by the Crown. For a company with even a nominal cash balance, this is a real risk, not a theoretical one.
