I haven’t live in Missouri for 20 years, I was referring to working in Texas for over 20 years as a non resident and never had any state income taxes withheld regardless of my state of residence.
All but nine states impose income tax on earnings.
And each one sets its own parameters for determining who must file a return and who owes income tax.
To say the states' rules are "all over the map" is apt here.
There are rules governing taxation of people working remotely for in-state and out-of-state employers. There are rules that will trigger the income tax for non-residents after they work instate for more than a minimum amount of time or earn a minimum amount of money doing so. And I’ve worked remotely from a state for more than 183 days last year, as much as 300 days a year, but no less than 200, I am characterized as a resident for tax purposes. Fact check that please will you, thanks
