(a) Computation of net earnings. In the case of any trade or business which is carried on by an individual who reports his income on the cash receipts and disbursements method, and in which, if it were carried on exclusively by employees, the major portion of the services would constitute agricultural labor as defined in section 3121(g) (see paragraph (a) of §1.1402(a)-13), net earnings from self-employment may, for a taxable year ending after 1954, at the option of the taxpayer, be computed as follows:
(1) Gross income $1,800 or less. If the gross income, computed as provided in paragraph (b) of this section, from such trade or business is $1,800 or less, the taxpayer may, at his option, treat as net earnings from self-employment from such trade or business an amount equal to 50 percent of such gross income. If the taxpayer so elects, the amount equal to 50 percent of such gross income shall be used in computing his self-employment income in lieu of his actual net earnings from such trade or business, if any.
(2) Gross income in excess of $1,800. If the gross income, computed as provided in paragraph (b) of this section, from such trade or business is more than $1,800, and the actual net earnings from self-employment from such trade or business are less than $900, the taxpayer may, at his option, treat $900 as net earnings from self-employment. If the taxpayer so elects, $900 shall be used in computing his self-employment income in lieu of his actual net earnings from such trade or business, if any. However, if the taxpayer's actual net earnings from such trade or business, as computed in accordance with §§1.1402(a)-1 through 1.1402(a)-3 are $900 or more, such actual net earnings shall be used in computing his self-employment income.
(b) Computation of gross income. For purposes of paragraph (a) of this section, gross income shall consist of the gross receipts from such trade or business reduced by the cost or other basis of property which was purchased and sold in carrying on such trade or business, adjusted (after such reduction) in accordance with the provisions of §1.1402(a)-3, relating to income and deductions not included in computing net earnings from self-employment.
(c) Two or more agricultural activities. If an individual is engaged in more than one agricultural trade or business within the meaning of paragraph (a) of §1.1402(a)-13 (for example, the business of ordinary farming and the business of cotton ginning), the gross income derived from each agricultural trade or business shall be aggregated for purposes of the optional method provided in paragraph (a) of this section for computing net earnings from self-employment.
(d) Examples. Application of the regulations prescribed in paragraphs (a) and (b) of this section may be illustrated by the following examples:
(e) Members of farm partnerships. The optional method provided by paragraph (a) of this section for computing net earnings from self-employment is not available to a member of a partnership with respect to his distributive share of the income or loss from any trade or business carried on by any partnership of which he is a member.
