Wow Ernie - that was really helpful. I can see how they are working it now. It happens that my wife's gross is within the same range as our joint gross so her filing non-joint would not gain us anything.
And I see the credit on the Michigan return - though it allows NY to keep about 40% of the tax we presumably owe, while granting Michigan about 60%.
Still though - is it proper for NY to claim 1.5% more than we would own Michigan, or for that matter any tax at all? My wife's employer counts how many days she works at the home office in NY state for tax reason - but that was zero in 2020. They led her to believe that unless she came to work in the state NY would not be taxing her.
I found this from 2006. If it's still germane then I think the employer's got it wrong (or we misunderstand) because it's pretty specific about when an employee would not have to pay NY taxes, and my wife doesn't meet enough of the requirements.

Don't know if you can shed any light on that, but do you think we misconstrued this?
Again - thanks! Big help!
Mike
