For taxable years beginning in 2015, the amount that can be used to reduce the net unearned income reported on the child's return that is subject to the "kiddie tax," is $1,050 (up from $1,000 in 2014). The same $1,050 amount is used to determine whether a parent may elect to include a child's gross income in the parent's gross income and to calculate the "kiddie tax". For example, one of the requirements for the parental election is that a child's gross income for 2015 must be more than $1,050 but less than $10,500.

For 2015, the net unearned income for a child under the age of 19 (or a full-time student under the age of 24) that is not subject to "kiddie tax" is $2,100.
