Dormant doesn't mean done: the filings every inactive UK company still owes
By Ibrahem Almahawe
Key takeaways for Arab directors
- 1A dormant UK company still owes annual dormant accounts (AA02) and a confirmation statement, every year
- 2Dormant status reduces the cost and complexity of filings, not the legal obligation to file
- 3Notify HMRC when your company becomes dormant, otherwise they'll continue to expect CT600 returns
- 4Missing dormant company filings for two or more years risks strike-off and, potentially, loss of any remaining company assets
- 5Dormant compliance is the most affordable category of UK company filing, the cost of ignoring it is significantly higher
Frequently asked questions
- Does a dormant UK company still have to file accounts and a confirmation statement?
- Yes. An inactive or dormant UK company must file annual dormant accounts (form AA02) with Companies House and submit its annual confirmation statement (£50 online fee) every year. Dormant status reduces the complexity of accounts, but never removes the statutory obligation to file.
- Do late filing penalties apply to dormant companies that miss their deadline?
- Yes. Companies House late filing penalties apply identically to dormant entities. If dormant accounts are filed late, penalties range from £150 up to £1,500, doubling in the second consecutive late year. Non-filing of the confirmation statement can also trigger prosecution and strike-off.
- How do you notify HMRC that a UK company is dormant?
- You must officially inform HMRC that the company is dormant for Corporation Tax purposes. Once HMRC accepts dormant classification, they issue formal confirmation that company tax returns (CT600) are not required until trading resumes, preventing automatic estimated tax assessments.
- Can a dormant company be struck off by Companies House if filings are ignored?
- Yes. Companies House treats dormant companies that fail to meet statutory deadlines exactly like active trading companies. They will issue warning notices to the registered office and publish a strike-off notice in the London Gazette, which dissolves the company if left unanswered.
Fileminder’s take, written for Arab UK company directors
A significant portion of Arab-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.
Dormant company filing is the simplest category of UK compliance work, but ignoring it still carries real consequences: up to £1,500 in financial penalties for late accounts (the confirmation statement has no fixed penalty scale, but it can bring a fine of up to £5,000, and persistent non-filing of either triggers strike-off action). If a company is dissolved, assets may pass to the Crown as bona vacantia.
