Earned income
(a) Earned income(1) In general. (i) For purposes of section 1348 and the regulations thereunder, the term earned income means any item of gross income which is earned income within the meaning of section 401(c)(2)(C) or 911(b) unless the item constitutes deferred compensation as defined in paragraph (b) of this section or is otherwise excluded by application of this paragraph. Thus, subject to such exceptions, the term includes: (A) Wages, salaries, professional fees, bonuses, amounts includible in gross income under section 83, commissions on sales or on insurance premiums, tips, and other amounts received, actually or constructively, as compensation for personal services actually rendered regardless of the medium or basis of payment. (B) Compensatory payments for personal services made prior to the time such services are actually rendered, provided such advance payments are not made for a purpose of minimizing Federal income taxes by reason of the application of section 1348, and are either customary in the particular profession, trade, or business, or are made for a bona fide business purpose. (C) Prizes and awards in recognition of personal services includible in gross income under section 74, amounts includible in gross income under section 79 (relating to group-term life insurance purchased for employees), and amounts includible in gross income under section 1379(b) (relating to contributions to qualified pension plans in the case of certain shareholder-employees); and (D) Gains (other than gain which is treated as capital gain under any provision of chapter 1) and net earnings derived from the sale or other disposition of, the transfer of any interest in, or the licensing of the use of property (other than good will) by an individual whose personal efforts created such property (ii) In the case of a nonresident alien individual, earned income includes only earned income from sources within the United States which is effectively connected with the conduct of a trade or business within the United States. (2) Earned income and employed assistants. The entire amount received as professional fees shall be treated as earned income if the taxpayer is engaged in a professional occupation, such as a doctor, dentist, lawyer, architect, or accountant, even though he employs assistants to perform part or all of the services, provided the patients or clients are those of the taxpayer and look to the taxpayer as the person responsible for the services performed. (3) Earned income from business in which capital is material. (i) If an individual is engaged in a trade or business (other than in corporate form) in which both personal services and capital are material income-producing factors, a reasonable allowance as compensation for the personal services actually rendered by the individual shall be considered earned income, but the total amount which shall be treated as the earned income of the individual from such a trade or business shall in no case exceed 30 percent of his share of the net profits of such trade or business (which share shall include any guaranteed payment (as defined by 1.707-1(c)) received from a partnership). For purpose of the preceding sentence, the term net profits of the trade or business means the excess of gross income from such trade or business (including income from all sources, whether or not subject to Federal income tax, and without taking into account any deductions which may be allowable under section 1202) over the deductions attributable to such trade or business. (ii) Whether capital is a material income-producing factor must be determined by reference to all the facts of each case. Capital is a material income-producing factor if a substantial portion of the gross income of the business is attributable to the employment of capital in the business, as reflected, for example, by a substantial investment in inventories, plant, machinery, or other equipment. In general, capital is not a material income-producing factor where gross income of the business consists principally of fees, commissions, or other compensation for personal services performed by an individual. Thus, the practice of his profession by a doctor, dentist, lawyer, architect, or accountant will not, as such, be treated as a trade or business in which capital is a material income-producing factor even though the practitioner may have a substantial capital investment in professional equipment or in the physical plant constituting the office from which he conducts his practice since his capital investment is regarded as only incidental to his professional practice. (iii) This subparagraph does not apply to gains and net earnings derived from the sale or other disposition of, the transfer of any interest in, or the licensing of the use of property by an individual whose personal efforts created such property which are, by reason of subparagraph (1)(i) of this paragraph, treated as earned income. Thus, for example, a research chemist's substantial capital investment in laboratory facilities which he uses to produce patentable chemical processes from which he derives gains within the meaning of this subdivision would not be considered a material income-producing factor. (4) Income in respect of a decedent. An item of gross income in respect of a decedent includible in the gross income of a person described in section described in section 691(a)(1) shall be treated as earned income in the hands of such person for purposes of subparagraph (1) of this paragraph if such item of gross income would have constituted earned income of the decedent had he lived and received such amount. See 1.1348-2(d)(3)(vi) for rules relating to attribution of tax preferences by reason of an item of income in respect of a decedent. (5) Exceptions to definition of earned income. For purposes of section 1348 and the regulations thereunder, the term earned income does not include: (i) Any distribution to which section 72(m)(5), relating to certain amounts received by owner-employees from a trust described in section 401(a) or under a plan described in section 403(a), applies, (ii) Any distribution to which section 402(e), relating to the treatment of certain total distributions from a trust described in section 401(a) or under a plan described in section 403(a), applies, (iii) Any distribution to which section 402(a)(2), relating to capital gains treatment of certain total distributions from a trust described in section 401(a), applies, (iv) Any distribution to which section 403(a)(2)(A), relating to capital gains treatment for certain distributions under a plan described in section 404(a)(2), applies, or (v) Any deferred compensation within the meaning of paragraph (b) of this section.
