If that is the case, the $7 make sense. I only leave a small capital in my company £5-7k for expenses/surprises by HMRC (aka IRS).
I don't think they're required to do this.. certainly it's possible to work via a brolly. Public sector clients have started asking some contractors to do this post-IR35.
Whilst I know agencies have their own policies on this, do you know of any legal reason why companies wouldn't be able to work with contractors who are self-employed for tax purposes (/instead/ of operating via a Ltd company)?
Obviously in most circumstances it's a really dumb idea to operate as self-employed instead of via a Ltd company.
Up until 2019 vast majority of calls/contracts offered to me (in the IT Audit/Risk/Security, GRC areas) were Ltd. I guess large Financial Services companies enjoy the 2mil liability insurance. Because if little-me messes up, their will get jack-shit :) It was also making the "contracting for a project and not an employee" scenario.
Remember this the next time you hear a talking head complaining that corporations pay zero taxes.
