I was actually offered this as a service by a company doing formations in the Seychelles (they were spamming people) - quite literally had a spammer tell me "no, don't buy my product, it isn't worth it"
They basically said the cost of company formation (doesn't really matter where, but anywhere that matters, like Panama or Seychelles or BVI or Macau or etc), mail handling monthly payments, virtual office payments, legal and accountant time, etc exceeds more than 99% of peoples' actual tax payment. That includes people making 500k. And that there is virtually no point in doing so. Doubly more if you are US based due to reporting requirements and massive additional costs for that.
IANAL, but based on what I've been told you are not able to easily do this if you are employed by a normal company - it requires that you hold a company in the first place to have intellectual property, branding to be able to licence cross-shell [easiest compared to trying to shuffle physical items of value around], etc, and that the company gets the payment, so people making 500k FAANG salaries are out as they are FTE employed.
And that your cost of finding the 'correct' accountant that has experience in this will far exceed your previous accountant cost.
