That's exactly my point. The company has had a tax deduction, but you have not received the income, so have not been taxed on it. There is a mismatch; not surprisingly they do not like this.
I presume you are you a participator in a close company; please confirm.
What are the possible solutions now (apart from advising HMRC) regarding past returns?
Errr, advising them. And running the risk, if you do not, that you suffer penalties and interest. You need to talk to your accountant regarding full disclosure.
Also, as the company's cashflow is still not brilliant, can I keep the loan and gift past and future interest?
I'm not sure I quite understand your question.
