What is Kiddie Tax?

The kiddie tax is a special tax rule that applies to unearned income of children under 19, or full-time students under 24. Established by the Tax Reform Act of 1986, this rule prevents parents from reducing their tax burden by transferring income-generating assets to their children who are typically in lower tax brackets.
