My "micro entity" limited company has not traded for last five years and there were no transactions but it had retained c£50k net profit in the bank account since 2014. I paid the two directors(self and wife) c£40k in divis in last financial year ending 31 Dec 2018. As well as submitting the Annual Confirmation and Micro Entity Accounts to Companies House as usual, do I need to submit CT 600 (?) to HMRC. There are no plans to commence trading as I have retired but I will keep it going just in case I need it in future ( and to pay out the remaining net profit of c£10k at some time).
