Is this a sole proprietorship business being reported on a SCH C? If so, who is the owner of the business? For a SCH C business, there can only be one owner, regardless of your maritial status or filing status. My bet is, you and you alone are the listed business owner. So your contribution is fine. But if your wife doesn't have at least $4000 of income that *she* earned, then you can't contribute to her ROTH.
