They already have a backdoor “exit tax”. They have weaponized the Franchise Tax Board to enforce it.
Every year since we escaped, we get an odd tax bill for some alleged underpayment from years ago. Along with huge penalties and interest, of course.
If you have ever had the misfortune of being forced to deal with the FTB, you already know you would prefer dealing with the mafia. By a wide margin.
I hope you’re not paying them.
