My employer withheld state income tax for NM, and when I filed my taxes for SC, I paid the full tax amount on my income, and claimed the entirety back from NM. I received a notice in the mail that my full taxable income is also being taxed in the state of NM and my refund amount would be reduced to reflect that.
So my question is, can my full income be taxed by two different states if they both have a state income tax?
