An umbrella company basically becomes your employer so they're paying all the correct tax and national insurance etc at source, the whole point of being inside ir35 is that you're paid paye and not invoicing.
You might not need to go through an umbrella company if their payroll will pay you paye but à lot of places won't do it for the hassle so just farm everything off to umbrella companies.
Yes, that's basically what I meant, but I've also worked for agencies that do it all in-house so don't work with umbrellas. Obviously this is a lot of work for payroll so the only places I know that do that are big studios that are constantly hiring in people on zero hrs contracts anyway.
