1. (a)In general. For each taxable year, the shared responsibility payment imposed on a taxpayer in accordance with § 1.5000A-1(c) is the lesser of—
   1. (1)The sum of the monthly penalty amounts; or
   2. (2)The sum of the monthly national average bronze plan premiums for the shared responsibility family.
2. (b)Monthly penalty amount
   1. (1)In general. Monthly penalty amount means, for a month that a nonexempt individual is not covered under minimum essential coverage, 1/12 multiplied by the greater of—
      1. (i)The flat dollar amount; or
      2. (ii)The excess income amount.
   2. (2)Flat dollar amount
      1. (i)In general. Flat dollar amount means the lesser of—
         1. (A)The sum of the applicable dollar amounts for all individuals included in the taxpayer's shared responsibility family; or
         2. (B)300 percent of the applicable dollar amount (determined without regard to paragraph (b)(2)(iii) of this section) for the calendar year with or within which the taxable year ends.
      2. (ii)Applicable dollar amount. Except as provided in paragraphs (b)(2)(iii) and (b)(2)(iv) of this section, the applicable dollar amount is—
         1. (A)$95 in 2014;
         2. (B)$325 in 2015; or
         3. (C)$695 in 2016.
      3. (iii)Special applicable dollar amount for individuals under age 18. If an individual has not attained the age of 18 before the first day of a month, the applicable dollar amount for the individual is equal to one-half of the applicable dollar amount (as expressed in paragraph (b)(2)(ii) of this section) for the calendar year in which the month occurs. For purposes of this paragraph (b)(2)(iii), an individual attains the age of 18 on the anniversary of the date when the individual was born. For example, an individual born on March 1, 1999, attains the age of 18 on March 1, 2017.
      4. (iv)Indexing of applicable dollar amount. In any calendar year after 2016, the applicable dollar amount is $695 as increased by the product of $695 and the cost-of-living adjustment determined under section 1(f)(3) for the calendar year. For purposes of this paragraph (b)(2)(iv), the cost-of-living adjustment is determined by substituting “calendar year 2015” for “calendar year 1992” in section 1(f)(3)(B). If any increase under this paragraph (b)(2)(iv) is not a multiple of $50, the increase is rounded down to the next lowest multiple of $50.
   3. (3)Excess income amount
      1. (i)In general. Excess income amount means the product of—
         1. (A)The excess of the taxpayer's household income over the taxpayer's applicable filing threshold (as defined in § 1.5000A-3(f)(2)); and
         2. (B)The income percentage.
      2. (ii)Income percentage. For purposes of this section, income percentage means—
         1. (A)1.0 percent for taxable years beginning in 2013;
         2. (B)1.0 percent for taxable years beginning in 2014;
         3. (C)2.0 percent for taxable years beginning in 2015; or
