Thanks for your response
If your accountant submits your return online then its an electronic signature. so just email me (and send a letter special delivery) asking him to cease acting for you personally for the year 2015/2016 and ask him to send you details of the income that has been paid to you from each of the companies during the period 06/04/2015 to 05/04/2016
And yes he cannot submit your return without you agreeing to this in writing and certainly not without the P60 benefit details
But if you are director in two then you should have been paid at least a minimum salary as you cannot just take dividends (you can if you are just a share holder) so you also need to establish what salary you should have been paid, and then did you actually get this salary!
Then you will automatically have partnership profits (usually 50% share but perhaps this is a different ratio) so you need these figures too
Is the £800 maintenance though - have you anything in writing that agrees this, did this only begin after you separated - were you paid £800 a month before you separated. Can you prove this is maintenance (is this declared to the benefit office??) D
I am not sure what you mean by opening a case with IR so they can monitor your income? Perhaps you can expand
I am off to bed now, so will deal with any reply in the morning - I hope that is acceptable
