accounting for discrepancy between federal income and total state income
i'm a non-resident of MA tho all my wages come from work in MA. My MA return (non resident) is alerting me that my federal income exceeds MA income by more than 10% and must be explained. I've included interest and dividends earned on my federal but not MA because I assume the banks and investments are not from MA. How does one determine what state bank and investment dividends and interest are associated with. Does it need to be declared on state return as part of overall income? Thanks
