When I was a new grad moving to the US and deciding where to live and work, the biggest draw of Seattle was its lack of income tax. Of course this particular $1 million threshold wouldn't apply to me until I'm very late in my career, or have a lucky year, or get married to a high-income person (the $1 million threshold applies to married couples, not just individuals) but Seattle loses a lot of its appeal if it's not…
I live in Texas. People move here and are flabbergasted by our property taxes.
Remains to be seen, as the next legislative session isn't until 2027.
