Self-employed individuals. Notwithstanding paragraph (b)(1) of this section, self-employed individuals' compensation can only be determined under paragraph (c)(2) of this section (with or without the modification permitted by paragraph (c)(4) of this section or a modification permitted by paragraph (c)(5) of this section) or by using an equivalent alternative compensation amount determined in accordance with paragraph (g)(1) of this section. These limitations on self-employed individuals do not affect their common-law employees. Thus, the compensation of common-law employees of a partnership or sole proprietorship may be defined using an alternative definition, provided the definition otherwise satisfies paragraph (c)(3), (d), (e), or (f) of this section. If an alternative definition of compensation under paragraph (c)(3), (d), (e), or (f) of this section is used for other employees to satisfy an applicable provision, the consistency requirement is only met if paragraph (g) of this section is used for the self-employed individuals.
