My mom moved to Idaho mid-year, dad lives in Missouri. ID and MO both require filing MFJ for state if you file MFJ federal. Also ID is community property, MO is not. Approximately 80% of the income is from dad's pensions and interest income, 20% from mom's interest income. What do I enter for income earned in Idaho? A quarter of the total, which would be mom's half of the total for half the year? Or only what mom earns from her investments/SSA for half the year, since MO isn't community property so she's not entitled to half of dad's income? Or the whole income they both earn for the year, and what belongs to dad will get taxed in MO and then ID deducts that? Or something else entirely?
