Inquiry about new joining the flat management company

The House is divided into 4 flats with share of freeholds and When I purchased the flat, I have been appointed as the director of this flat management company. Do I need to submit any form to let HMRC knows I become the director of this company? Or need to do any other administrative work to HMRC? Thank you.

Hi Savio Ng,
You are required to register the company with Companies House, once this has been done Companies House will inform HMRC who will set up a Corporation Tax record and issue a Unique Taxpayers Reference.
Once you have received this you can advise HMRC that the company is a Flat Management Company and request Dormancy which will exclude your company from the obligation to submit tax returns.
Thank you.
