In theory as a retail business, I think it would be more beneficial if we were a Ltd company, however, my wife wants to be a part of it as either company Director or company secretary but what I'm trying to work out as she is currently working full and we could not afford her to leave this job at the moment, in terms of tax if she did come on board as a company director or company secretary, how will this impact her if we went down this route, from a tax point of view, will she pay a higher tax etc....?
