Going to be straight up and say that I made a mistake. Around this time last year, I created a company name for a web project I was working on. Fast forward a year, I didn't work on the project and it got left behind due to other commitments. I have now been contacted by HM Revenue & Customs saying that I need to deliver a company tax return. There has been absolutely zero activity for the company. No transactions or anything. At no point have I set the company as dormant (if that is possible.) After I file the tax return, I wish to close the limited company so I don't have to deal with this again. What is the best way to go about filing this company tax return and then closing the company? I saw a video on youtube from saying that it is possible to file accounts for dormant companies but do you have to first of all set the status as dormant? What do you put in the number of shares and value of each share? Many thanks in advance.
