I too have many IC agreements I had to sign as a DP that I can fax you. Go to https://www.nedmiller.com or https://www.bizvideo.com and hit the email button.
However, I personally know that IC agreements will not keep the IRS from considering your freelancers employees. Rather, it is more protection as a work-for-hire status in case the vendor (freelancer) claims part of the copyright or wants to use the footage for themselves, like DPs may want to do.
The reason I know they are useless in regards to protection from withholding taxes: I had a working relationship with two prod companies who were audited and the IRS does not care about ICs to establish freelance status. They have a checklist, about 12 items long that determines whether someone is an employee or IC. Stuff like: Does the producer tell him when to show up? Does the producer supervise his work? Does the producer provide the tools (like rent the grip truck)? Does the freelancer bill hourly? etc. Whatever you do, never allow a non-incorporated freelancer to put the word Overtime on their invoice!!!!! That last sentence may be the best advice you ever saw on the internet. The word Overtime firmly establishes in the eyes of the IRS that the person is an EMPLOYEE (meaning you should have withheld taxes) regardless of an IC they signed.
So you can see that just a signature on an IC agreement means nothing to them, remember they are responsible for so much in taxes and fines per audit hour. When all factors are equal hire the INCORPORATED crew member over the non-incorporated. The IC agreement may help if someone gets injured on your job IF you have a Workers Comp policy, but it is useless, from what I’ve seen, for protection in establishing someone as a “freelancer”. Only the IRS determines that.
I don’t know much about tax and legal issues but I do know about this IC angle.
