Helping son with taxes. He worked 5 months in New Mexico. Lived the rest of the time in a Texas (no state income tax). I listed him as non resident on the New Mexico State income tax form. But what do I list for interest, dividends, capital gains/losses? The entire year’s worth or just the 5 months he was in New Mexico? I have yet to see a question asking what time he spent there (less than 6 months).
