(a) Imposition of tax

There is hereby imposed a tax on the failure of any applicable pension plan to meet the requirements of subsection (e) with respect to any applicable individual.

(b) Amount of tax

(1) In general

The amount of the tax imposed by subsection (a) on any failure with respect to any applicable individual shall be $100 for each day in the noncompliance period with respect to such failure.

(2) Noncompliance period

For purposes of this section, the term “noncompliance period” means, with respect to any failure, the period beginning on the date the failure first occurs and ending on the date the notice to which the failure relates is provided or the failure is otherwise corrected.

(c) Limitations on amount of tax

(1) Tax not to apply where failure not discovered and reasonable diligence exercised

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 any person subject to liability for the tax under subsection (d) did not know that the failure existed and exercised reasonable diligence to meet the requirements of subsection (e).

(2) Tax not to apply to failures corrected within 30 days

No tax shall be imposed by subsection (a) on any failure if—

(A) any person subject to liability for the tax under subsection (d) exercised reasonable diligence to meet the requirements of subsection (e), and

(B) such person provides the notice described in subsection (e) during the 30-day period beginning on the first date such person knew, or exercising reasonable diligence would have known, that such failure existed.

(3) Overall limitation for unintentional failures

(A) In general

If the person subject to liability for tax under subsection (d) exercised reasonable diligence to meet the requirements of subsection (e), the tax imposed by subsection (a) for failures during the taxable year of the employer (or, in the case of a multiemployer plan, the taxable year of the trust forming part of the plan) shall not exceed $500,000. For purposes of the preceding sentence, all multiemployer plans of which the same trust forms a part shall be treated as 1 plan.

(B) Taxable years in the case of certain controlled groups

For purposes of this paragraph, if all persons who are treated as a single employer for purposes of this section do not have the same taxable year, the taxable years taken into account shall be determined under principles similar to the principles of section 1561.

(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 or otherwise inequitable relative to the failure involved.

(d) Liability for tax
