My husband's income all comes through his Idaho-based LLC, via 1099-MISC and 1099-NECs. We lived in ID until March 2020, when we moved to Montana. I'm clear on how to file as part-year residents, but getting conflicting info on how to report this income.
Do I count all of these earnings on the ID state return, and then when reporting on the MT return, indicate that it has already been accounted for on the ID return? Or, since we are now MT residents, is the income (April-Dec, after we moved) counted as MT income, even thought it comes from the ID-based LLC? In the latter case, I would only report Jan-Mar income on the ID state return.
Any help is appreciated!
