So far formed 4 with 3 going dormant.Absolute tosh, how many limited companies have you formed, I have formed 6 in total, one is still trading i have also formed one company that never traded, it lasted two years before we decided we did not need it, I never informed the HMRC about that as you do not need to until it starts trading, ie conducting business.

I understand you doing things the wrong way make you believe you do not need to do them. Getting away with something isn't the same as it being the actual process.
