I guess it depends on situations or state: whether or not you can split your investmentinĉome with your spouse depends on whether or not you shared in the purchase of the investment in the first place and how much your spouse contributed. Certain states have laws about community property defining how they expect MFS couples to share, or allocate, income.in general ,in community pty states, you need to combine the investment income from community assets and divide the result in half. So,you must report half the community investment income. the husband needsto Report his entire separate investment income on his own return so does the wife.. spouses own equally almost all property either one acquires during the marriage, regardless of whose name the property is in half of each spouse's income is owned by the other spouse during the marriage.however, some differences among comm. Pty states though.
however, in Most non comm. pty states, it's usually easy to tell which spouse owns what. If only your name is on the acct, registration document, or other title paper, it's yours. If you and your spouse both have your name on the acct, you each own a half interest in the property unless the acct. document says otherwise.
