Dormant company accounts deadline
A company classified as dormant by Companies House must still file dormant company accounts annually. The deadline is the same as for active companies: 9 months after the accounting reference date for private companies, 6 months for public.
What is this filing?
Dormant accounts are a simplified set of accounts confirming the company has had no significant accounting transactions in the period. Form AA02 is used for dormant private limited companies; full dormant accounts are required for dormant subsidiaries above small-company thresholds.
When is it due?
Same as standard annual accounts: 9 months after the ARD for private companies, 6 months for public companies. Failure to file dormant accounts attracts the same late-filing penalties as active companies.
What's the penalty for missing it?
Identical to active-company penalties: £150 (1 month late), £375 (1–3 months), £750 (3–6 months), £1,500 (over 6 months). Doubled for second consecutive year of lateness. Same penalty regime regardless of dormant or active status.
