Thanks for the response to my original query. However, I was under the impression that the CRO can unilaterally strike off a company if a return is late. On CRO website, it mentions the serious consequences of being struck-off e.g. assets becoming property of state, loss of limited liability, disqualification of director.
In my example above, Mr A does not care if CRO struck off the company as it is dormant. It has no assets, the only creditor is himself and he intends to become a sole trader. Therefore, he couldn't care less about the "dire consequences" of CRO strike-off. My point is that it seems cheaper to let a company die than to do the "right thing" by preparing accounts to cessation and pay late CRO fees (minimum €1,200).
