29 CFR § 541.600 - Amount of salary required.
(a) To qualify as an exempt executive, administrative or professional employee under section 13(a)(1) of the Act, an employee must be compensated on a salary basis at a rate per week of not less than the 40th percentile of weekly earnings of full-time nonhourly workers in the lowest-wage Census Region. As of December 1, 2016, and until a new rate is published in the Federal Register by the Secretary, such an employee must be compensated on a salary basis at a rate per week of not less than $913 (or $767 per week, if employed in American Samoa by employers other than the Federal government), exclusive of board, lodging or other facilities. Beginning January 1, 2020, and every three years thereafter, the Secretary shall update the required salary amount pursuant to § 541.607. Administrative and professional employees may also be paid on a fee basis, as defined in § 541.605.
(b) The required amount of compensation per week may be translated into equivalent amounts for periods longer than one week. The requirement will be met if the employee is compensated biweekly on a salary basis of $1,826, semimonthly on a salary basis of $1,978, or monthly on a salary basis of $3,956. However, the shortest period of payment that will meet this compensation requirement is one week. Beginning January 1, 2020, and every three years thereafter, the Secretary shall update the required salary amount pursuant to § 541.607 and the updated salary amount may be paid weekly, biweekly, semimonthly, or monthly on a salaried basis.
(c) In the case of academic administrative employees, the compensation requirement also may be met by compensation on a salary basis at a rate at least equal to the entrance salary for teachers in the educational establishment by which the employee is employed, as provided in § 541.204(a)(1).
(d) In the case of computer employees, the compensation requirement also may be met by compensation on an hourly basis at a rate not less than $27.63 an hour, as provided in § 541.400(b).
(e) In the case of professional employees, the compensation requirements in this section shall not apply to employees engaged as teachers (see§ 541.303); employees who hold a valid license or certificate permitting the practice of law or medicine or any of their branches and are actually engaged in the practice thereof (see§ 541.304); or to employees who hold the requisite academic degree for the general practice of medicine and are engaged in an internship or resident program pursuant to the practice of the profession (see§ 541.304). In the case of medical occupations, the exception from the salary or fee requirement does not apply to pharmacists, nurses, therapists, technologists, sanitarians, dietitians, social workers, psychologists, psychometrists, or other professions which service the medical profession.
