Even if you're a dependent, you'll generally need to file your own 2021 tax return if:
- Your earned income (money you made by working) exceeds $12,550
- Your unearned income (interest, dividends, capital gains, etc.) exceeds $1,100
- Your business or self-employment net income (gross minus expenses) is at least $400
- Your gross income (earned plus unearned) exceeds the larger of $1,100 or your earned income (up to $12,200) plus $350
But even if your income falls below these filing requirements, you'll want to file your own tax return to get a refund of any federal or state taxes withheld from your paychecks.
