(a) In general. Section 4980H applies to an applicable large employer and to all of the applicable large employer members that comprise that applicable large employer.

(b) Determining applicable large employer status—(1) In general. An employer's status as an applicable large employer for a calendar year is determined by taking the sum of the total number of full-time employees (including any seasonal workers) for each calendar month in the preceding calendar year and the total number of FTEs (including any seasonal workers) for each calendar month in the preceding calendar year, and dividing by 12. The result, if not a whole number, is then rounded to the next lowest whole number. If the result of this calculation is less than 50, the employer is not an applicable large employer for the current calendar year. If the result of this calculation is 50 or more, the employer is an applicable large employer for the current calendar year, unless the seasonal worker exception in paragraph (b)(2) of this section applies.

(2) Seasonal worker exception. If the sum of an employer's full-time employees and FTEs exceeds 50 for 120 days or less during the preceding calendar year, and the employees in excess of 50 who were employed during that period of no more than 120 days are seasonal workers, the employer is not considered to employ more than 50 full-time employees (including FTEs) and the employer is not an applicable large employer for the current calendar year. In the case of an employer that was not in existence on any business day during the preceding calendar year, if the employer reasonably expects that the sum of its full-time employees and FTEs for the current calendar year will exceed 50 for 120 days or less during the calendar year, and that the employees in excess of 50 who will be employed during that period of no more than 120 days will be seasonal workers, the employer is not an applicable large employer for the current calendar year. For purposes of this paragraph (b)(2) only, four calendar months may be treated as the equivalent of 120 days. The four calendar months and the 120 days are not required to be consecutive.

(3) Employers not in existence in preceding calendar year. An employer not in existence throughout the preceding calendar year is an applicable large employer for the current calendar year if the employer is reasonably expected to employ an average of at least 50 full-time employees (taking into account FTEs) on business days during the current calendar year and it actually employs an average of at least 50 full-time employees (taking into account FTEs) on business days during the calendar year. An employer is treated as not having been in existence throughout the prior calendar year only if the employer was not in existence on any business day in the prior calendar year. See paragraph (b)(2) of this section for the application of the seasonal worker exception to employers not in existence in the preceding calendar year.

(4) Special rules for government entities, churches, and conventions and associations of churches. [Reserved]

(5) Transition rule for an employer's first year as an applicable large employer. With respect to an employee who was not offered coverage by the employer at any point during the prior calendar year, if the applicable large employer offers coverage to the employee on or before April 1 of the first calendar year for which the employer is an applicable large employer, the employer will not be subject to an assessable payment under section 4980H by reason of its failure to offer coverage to the employee for January through March of that year, provided that this relief applies only with respect to potential liability under section 4980H(b) (for January through March of the first calendar year for which the employer is an applicable large employer) if the coverage offered by April 1 provides minimum value. If the employer does not offer coverage to the employee by April 1, the employer may be subject to a section 4980H(a) assessable payment with respect January through March of the first calendar year for which the employer is an applicable large employer in addition to any later calendar months for which coverage was not offered. If the employer offers coverage to the employee by April 1 that does not provided minimum value, the employer may be subject to a section 4980H(b) assessable payment with respect to the employee for January through March of the first calendar year for which the employer is an applicable large employer in addition to any later calendar months for which coverage does not provide minimum value or is not affordable. This rule applies only during the first year that an employer is an applicable large employer (and would not apply if, for example, the employer falls below the 50 full-time employee (plus FTE) threshold for a subsequent calendar year and then increases employment and becomes an applicable large employer again).

(c) Full-time equivalent employees (FTEs)—(1) In general. In determining whether an employer is an applicable large employer, the number of FTEs it employed during the preceding calendar year is taken into account. All employees (including seasonal workers) who were not employed on average at least 30 hours of service per week for a calendar month in the preceding calendar year are included in calculating the employer's FTEs for that calendar month.

(2) Calculating the number of FTEs. The number of FTEs for each calendar month in the preceding calendar year is determined by calculating the aggregate number of hours of service for that calendar month for employees who were not full-time employees (but not more than 120 hours of service for any employee) and dividing that number by 120. In determining the number of FTEs for each calendar month, fractions are taken into account; an employer may round the number of FTEs for each calendar month to the nearest one hundredth.

(d) Examples. The following examples illustrate the rules of paragraphs (a) through (c) of this section. In these examples, hours of service are computed following the rules set forth in §54.4980H-3, and references to years refer to calendar years unless otherwise specified. The employers in Example 2 through Example 6 are each the sole applicable large employer member of the applicable large employer, as determined under section 414(b), (c), (m), and (o).

(e) Additional guidance. With respect to an employer's status as an applicable large employer, the Commissioner may prescribe additional guidance of general applicability, published in the Internal Revenue Bulletin (see §601.601(d)(2)(ii)(b) of this chapter).

(f) Effective/applicability date. This section is applicable for periods after December 31, 2014.
