Your dependent child can file a return even if you are claiming her. Be sure on her return she selects that someone else can claim her as a dependent.
Even if you're a dependent, you'll generally need to file your own 2017 tax return if:
- Your earned income (money you made by working) exceeds $6,350, or
- Your unearned income (interest, dividends, capital gains, etc.) exceeds $1,050, or
- Your business or self-employment net income (gross minus expenses) is at least $400, or
- Your gross income (earned plus unearned) exceeds the larger of $1,050 or your earned income (up to $6,000) plus $350.
