- Investment Income Children with investment income may have part or all of this income taxed at their parents’ tax rate rather than at the child’s rate. Investment income includes interest, dividends, capital gains and other unearned income.
- Age Requirement The child’s tax must be figured using the parents’ rates if the child has investment income of more than $1,900 and meets one of three age requirements for 2010:
- Was under age 18 at the end of the year,
- Was age 18 at the end of the year and did not have earned income that was more than half of his or her support, or
- Was a full-time student over age 18 and under age 24 at the end of the year and did not have earned income that was more than half of his or her support.
