My son worked eight months in Pennsylvania then moved to Kansas and worked the rest of the year there. How do I divide his dividend/capital gains income between the two states? Do I divide it or should it all go to one state?
are you doing your return or helping with his?
He has to report his own income tax.
Divide ("allocate") the income based on where he lived when the dividends/capital gains were earned, i.e. when the dividends were posted to his personal account (or reinvested) and when he sold the stocks (for capital gains).
