A dormant company still has to file accounts for year end, so zero trading zero expense a big fat zero. Not sure why they need the form. Frankly not sure how to complete it, if there is no accounts then what is the point apart from not getting a fine. Talk about bureaucratic night mares, they must fill in a form at companies house for cubic feet of breathable air during the course of there day...! I wished i invented forms and charged a royalty for the use.
