If a child is subject to the kiddie tax (see Q 8601), it is possible that he or she may be subject to AMT. Under special rules, the AMT exemption of a child subject to the kiddie tax in 2026 is the lesser of the AMT exemption for a single taxpayer ($90,100) or the total of the child's earned income plus $9,750.1
