What counts as a dependent?

Dependents can affect filing status and credits. Here’s a simple overview of the two common categories.

Qualifying Child (common examples)

  • Must be related (child, stepchild, foster child, sibling, etc.)
  • Lived with you more than half the year (some exceptions apply)
  • Generally under age 19, or under 24 if a full-time student
  • Did not provide more than half of their own support

Qualifying Relative (not necessarily your child)

  • May live with you all year OR be a specific type of relative
  • You generally provide more than half of their support
  • Their income must be under certain limits (varies by rules/year)
  • They can’t be claimed as someone else’s qualifying child

Documents that help

  • School/medical records showing address
  • Daycare records, lease docs, or official mail showing residency
  • Support records (who paid what) for relatives you support
  • Social Security numbers/ITINs for dependents
Quick tip

If more than one person could claim the same child, there are “tie-breaker” rules. Don’t guess—get it right to avoid IRS issues.
