Having completely messed up, I wondered if anyone on here had experience or advice on this fairly major problem I've just come across. I've run a business which was on the edge a bit at the turn of the year and has died a death very recently, right at the time the corporation tax was due which we couldn't afford to pay. So, the HMRC are going through the motions, the notice is in the gazette and the company will be struck off in a couple of months. The ridiculous mistake I've made is that doing mine and my wife's self assessments, I've completely miscalculated her payments, as she has another job and was a director by name only with our company, but taking dividends. I've never had a bill before under self assessment, when I've always earned a small salary and around £40k in dividends, but that's always been done via an accountant. This time, I've done it because we can't afford one. I thought the dividends were not taxable at self assessment and put through that she earned £0 salary from the company, so she doesn't owe any tax. I was speaking to a friend about the situation and he thinks we'd owe around £7k or £8k in self assessment tax because I should have declared her dividends. We just cannot afford this at all as now I have zero income. The uncomfortable question is, will HMRC investigate my wife personal accounts in a business that has been struck off? I appreciate this isn't moral or right in any way, but we've 3 kids and could lose everything.
