LEM.
You are going to hate me, as I am going to be brutally honest, but I think I can, as I have followed you (with sympathy for you and your family's situation) the last few years. (QuintessentialShadows here)
However, did you just now start preparing your annual accounts? The dead line for paying corporation tax was 1/01/09 for last accounting period, was it not?
If you are to receive a 2k tax bill, this means your partners firm has made some profits? Or is the tax bills due to lacking receipts and you have not filed expenses?
Have you claimed back VAT on expenses?
Can you look everywhere for as many receipts and invoices as you can and incorporate these in your next VAT return so you get some money back, and also include them in your annual accounts this year to get your profits down a little?
You need to speak to your accountant on monday.
Did you not realize you need to keep bank statements and open "official" letters? You have a duty to keep them for 10 years. But this is salvagable, so you can ask the bank to send you copies.
If you do online banking, the onus is ON YOU to download and manage your statements, this is easily done in excel. However, by the sound if it, you shouldnt give yourself too much extra work at the moment, you are much too fragile.
However, I pretty much blame your partner. He is the boss. It is his business. He should keen an eye on you, manage you, and ensure not only that you do your job, but that you are able to do it, by him ensuring you have all the receipts and invoices.
This is not a job you can do with a demanding child around. You need peace and quiet, and some "head space". You need your own work space, where you can file all your paperwork, and have it easily accessible.
Managing company accounts from home, in "your own" time is a hard and responsible job. It requires time and quiet, and space to do it. Is dd going to her preschool sessions?
You CAN sort this. Get a head start tonight after dd is in bed, with your dp, look for the paperwork, and speak to the accountant on monday. You CAN do this. You CAN see through the fog of your head. You know you are intelligent, you better believe it too!
