26 U.S.C. § 4980D : US Code - Section 4980D: Failure to meet certain group health plan requirements

    (a) General rule
      There is hereby imposed a tax on any failure of a group health
    plan to meet the requirements of chapter 100 (relating to group
    health plan requirements).
    (b) Amount of tax
      (1) In general
        The amount of the tax imposed by subsection (a) on any failure
      shall be $100 for each day in the noncompliance period with
      respect to each individual to whom such failure relates.
      (2) Noncompliance period
        For purposes of this section, the term "noncompliance period"
      means, with respect to any failure, the period - 
          (A) beginning on the date such failure first occurs, and
          (B) ending on the date such failure is corrected.
      (3) Minimum tax for noncompliance period where failure discovered
        after notice of examination
        Notwithstanding paragraphs (1) and (2) of subsection (c) - 
        (A) In general
          In the case of 1 or more failures with respect to an
        individual - 
            (i) which are not corrected before the date a notice of
          examination of income tax liability is sent to the employer,
          and
            (ii) which occurred or continued during the period under
          examination,

        the amount of tax imposed by subsection (a) by reason of such
        failures with respect to such individual shall not be less than
        the lesser of $2,500 or the amount of tax which would be
        imposed by subsection (a) without regard to such paragraphs.
        (B) Higher minimum tax where violations are more than de
          minimis
          To the extent violations for which any person is liable under
        subsection (e) for any year are more than de minimis,
        subparagraph (A) shall be applied by substituting "$15,000" for
        "$2,500" with respect to such person.
        (C) Exception for church plans
          This paragraph shall not apply to any failure under a church
        plan (as defined in section 414(e)).
    (c) Limitations on amount of tax
      (1) Tax not to apply where failure not discovered exercising
        reasonable diligence
        No tax shall be imposed by subsection (a) on any failure during
      any period for which it is established to the satisfaction of the
      Secretary that the person otherwise liable for such tax did not
      know, and exercising reasonable diligence would not have known,
      that such failure existed.
      (2) Tax not to apply to failures corrected within certain periods
        No tax shall be imposed by subsection (a) on any failure if - 
          (A) such failure was due to reasonable cause and not to
        willful neglect, and
          (B)(i) in the case of a plan other than a church plan (as
        defined in section 414(e)), such failure is corrected during
        the 30-day period beginning on the first date the person
        otherwise liable for such tax knew, or exercising reasonable
        diligence would have known, that such failure existed, and
          (ii) in the case of a church plan (as so defined), such
        failure is corrected before the close of the correction period
        (determined under the rules of section 414(e)(4)(C)).
      (3) Overall limitation for unintentional failures
        In the case of failures which are due to reasonable cause and
      not to willful neglect - 
        (A) Single employer plans
          (i) In general
            In the case of failures with respect to plans other than
          specified multiple employer health plans, the tax imposed by
          subsection (a) for failures during the taxable year of the
          employer shall not exceed the amount equal to the lesser of -
          
              (I) 10 percent of the aggregate amount paid or incurred
            by the employer (or predecessor employer) during the
            preceding taxable year for group health plans, or
              (II) $500,000.
          (ii) Taxable years in the case of certain controlled groups
            For purposes of this subparagraph, if not all persons who
          are treated as a single employer for purposes of this section
          have the same taxable year, the taxable years taken into
          account shall be determined under principles similar to the
          principles of section 1561.
        (B) Specified multiple employer health plans
          (i) In general
            In the case of failures with respect to a specified
          multiple employer health plan, the tax imposed by subsection
          (a) for failures during the taxable year of the trust forming
          part of such plan shall not exceed the amount equal to the
          lesser of - 
              (I) 10 percent of the amount paid or incurred by such
            trust during such taxable year to provide medical care (as
            defined in section 9832(d)(3)) directly or through
            insurance, reimbursement, or otherwise, or
              (II) $500,000.

          For purposes of the preceding sentence, all plans of which
          the same trust forms a part shall be treated as one plan.
          (ii) Special rule for employers required to pay tax
            If an employer is assessed a tax imposed by subsection (a)
          by reason of a failure with respect to a specified multiple
          employer health plan, the limit shall be determined under
          subparagraph (A) (and not under this subparagraph) and as if
          such plan were not a specified multiple employer health plan.
      (4) Waiver by Secretary
        In the case of a failure which is due to reasonable cause and
      not to willful neglect, the Secretary may waive part or all of
      the tax imposed by subsection (a) to the extent that the payment
      of such tax would be excessive relative to the failure involved.
    (d) Tax not to apply to certain insured small employer plans
      (1) In general
        In the case of a group health plan of a small employer which
      provides health insurance coverage solely through a contract with
      a health insurance issuer, no tax shall be imposed by this
      section on the employer on any failure (other than a failure
      attributable to section 9811) which is solely because of the
      health insurance coverage offered by such issuer.
      (2) Small employer
        (A) In general
          For purposes of paragraph (1), the term "small employer"
        means, with respect to a calendar year and a plan year, an
        employer who employed an average of at least 2 but not more
        than 50 employees on business days during the preceding
        calendar year and who employs at least 2 employees on the first
        day of the plan year. For purposes of the preceding sentence,
        all persons treated as a single employer under subsection (b),
        (c), (m), or (o) of section 414 shall be treated as one
        employer.
        (B) Employers not in existence in preceding year
          In the case of an employer which was not in existence
        throughout the preceding calendar year, the determination of
        whether such employer is a small employer shall be based on the
        average number of employees that it is reasonably expected such
        employer will employ on business days in the current calendar
        year.
        (C) Predecessors
          Any reference in this paragraph to an employer shall include
        a reference to any predecessor of such employer.
      (3) Health insurance coverage; health insurance issuer
        For purposes of paragraph (1), the terms "health insurance
      coverage" and "health insurance issuer" have the respective
      meanings given such terms by section 9832.

      The following shall be liable for the tax imposed by subsection
    (a) on a failure:
        (1) Except as otherwise provided in this subsection, the
      employer.
        (2) In the case of a multiemployer plan, the plan.
        (3) In the case of a failure under section 9803 (relating to
      guaranteed renewability) with respect to a plan described in
      subsection (f)(2)(B), the plan.

        been in had such failure not occurred.
