As SEO/Web marketing usualy consists of working on clients sites, doing work on marketing, work on SEO and usually has a monthly retainer, is ir35 a potential problem?
If I have read the question right, then are you asking
if I own a Ltd co, but the company works for many different clients, can I still get done within IR35, then I would say the answer is yes, because your only client will be your own ltd co.
ouch brain fart. yes I am not sure what happened then. If the Ltd co had 1 client then IR35 would kick in yes?
Office of Tax Simplification (OTS).
You are presuming that's good news.
Don't forget that they may "simplify" things by moving the goal posts in the direction that you don't like!
and don't forget IR35 repel is supposed to be on the agenda for the OTS
