26 CFR § 1.73-1 - Services of child.
(a) Compensation for personal services of a child shall, regardless of the provisions of State law relating to who is entitled to the earnings of the child, and regardless of whether the income is in fact received by the child, be deemed to be the gross income of the child and not the gross income of the parent of the child. Such compensation, therefore, shall be included in the gross income of the child and shall be reflected in the return rendered by or for such child. The income of a minor child is not required to be included in the gross income of the parent for income tax purposes. For requirements for making the return by such child, or for such child by his guardian, or other person charged with the care of his person or property, see section 6012.
(b) In the determination of taxable income or adjusted gross income, as the case may be, all expenditures made by the parent or the child attributable to amounts which are includible in the gross income of the child and not of the parent solely by reason of section 73 are deemed to have been paid or incurred by the child. In such determination, the child is entitled to take deductions not only for expenditures made on his behalf by his parent which would be commonly considered as business expenses, but also for other expenditures such as charitable contributions made by the parent in the name of the child and out of the child's earnings.
(c) For purposes of section 73, the term “parent” includes any individual who is entitled to the services of the child by reason of having parental rights and duties in respect of the child. See section 6201(c) and the regulations in Part 301 of this chapter (Procedure and Administration) for assessment of tax against the parent in certain cases.
