It's a tax that's applied on your child's investment income of more than $1,900. The tax is meant to discourage parents from reducing their own taxes by shifting investments to their children, who normally have lower tax brackets.
While it once affected only children under age 14, it can be imposed for 2009 on the investment income of children up to age 23, depending on the circumstances.
NOTE: The tax applies only to investment income, such as interest and dividends, not income from wages or self-employment. Investment income includes interest and dividends.

Investment income above that amount is subject to the kiddie tax – that is, your marginal tax rate, Marginal tax rate is the rate of tax you pay on the last dollar you earned. That could be as low as 10% or 15% or as high as 28%, 33% or 35%.
