If a company doesnāt file their Corporation Tax return, VAT or PAYE return then HMRC actually have the legal authority to issue an assessed/estimated bill for payment based on the average bills of similar sized companies.
But this is not HMRC who have closed the company. For them to do so requires them to submit a Winding Up Petition to the High Court and then obtain a Winding Up Order. All of which has to be published in the London Gazette records which are publicly available online. Nothing has been published to that effect.
It is the Registrar of Companies who has had the company struck off and so it no longer exists as a legal entity.
So anything that the company did that requires legal entity status it is now unable to do - they canāt hold a speedway licence, canāt employ people, canāt be the employer sponsor for work visas etc etc
