@ Franco
Would you mind telling me why you're off? I'm not a contractor, never have been, so I don't know the situation at all and my view of it is completely naive.
But, I assume you are a Ltd company, and pay yourself a salary + dividends? And you pay full employer's and individual NI on your salary? So what's changing?
Or are you saying that you break the rules in order to lower your rates as otherwise you'll be undercut by all the other contractors also breaking the rules?
