I've talked to a partner at an IP law firm in Austin, Texas. They do a lot of business with the tech companies like Amazon, and wanted to hire a new attorney based in SV, since most of their work is done remotely with the SV office of Amazon, even though there's a local Amazon office down the street in Austin, too.

Well, it turns out, if they'd have done so, they'd be required to pay taxes on the income of their whole partnership from most of their clients, because most of the companies they do business with are based in Cali, even though all the rest of their lawyers are based in Texas.

Guess how they decided to proceed after receiving such advice from the state?
