I already run my own company, as a sole trader. It was not set up long ago, but an opportunity has arose which I want to take.

I now want to form a new partnership in a different business, can I still use the money that I originally put into the bank account of my own company? Or is this then taxable? Or how do I get around this problem and others like it?

I might just be being stupid and it might be a really simple solution, but I don't want to do things incorrectly.

Thanks,
Luke
