Summary

A tax applies when a pension plan cuts the rate at which future benefits grow but does not give the required notice about that change. The tax is $100 for each day that each affected person goes without the notice. The daily tax runs from the day the notice was missed until the notice is given or the problem is fixed. No tax is charged if the person who would pay it didn’t know about the missed notice and acted with reasonable care. No tax is charged if that person acted with reasonable care and then gave the required notice within 30 days after they knew (or reasonably should have known) about the problem. If the responsible person showed reasonable care, the total tax for the year cannot be more than $500,000. The IRS can reduce or cancel the tax if the failure was for a good reason and not on purpose. The employer is responsible for the tax for single-employer plans. For multiemployer plans, the plan itself is responsible. When a plan is changed to cut future accruals, the plan administrator must give a clear written notice to each affected person, to any union that represents them, and to each employer who must contribute. The notice must be easy to understand and give enough details under IRS rules. The IRS can allow a simpler notice or exempt small plans (fewer than 100 people with accrued benefits) and plans that let people pick the old or new formula. The notice must be given a reasonable time before the change takes effect, can be sent to a person someone designates in writing, and will count as given early if the change is not materially changed before it is adopted. "Applicable individual" means plan participants and certain alternate payees. "Applicable pension plan" means certain defined benefit plans or account plans that must meet funding rules. The IRS may allow use of new technologies to send the notice.

Title 26, §4980F

Internal Revenue Code — Source: USLM XML via OLRC

(a)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)(1)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)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)(1)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)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)(A)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)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)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)The following shall be liable for the tax imposed by subsection (a):
(1)In the case of a plan other than a multiemployer plan, the employer.
(2)In the case of a multiemployer plan, the plan.
(e)(1)If an applicable pension plan is amended to provide for a significant reduction in the rate of future benefit accrual, the plan administrator shall provide the notice described in paragraph (2) to each applicable individual (and to each employee organization representing applicable individuals) and to each employer who has an obligation to contribute to the plan.
(2)The notice required by paragraph (1) shall be written in a manner calculated to be understood by the average plan participant and shall provide sufficient information (as determined in accordance with regulations prescribed by the Secretary) to allow applicable individuals to understand the effect of the plan amendment. The Secretary may provide a simplified form of notice for, or exempt from any notice requirement, a plan—
(A)which has fewer than 100 participants who have accrued a benefit under the plan, or
(B)which offers participants the option to choose between the new benefit formula and the old benefit formula.
(3)Except as provided in regulations, the notice required by paragraph (1) shall be provided within a reasonable time before the effective date of the plan amendment.
(4)Any notice under paragraph (1) may be provided to a person designated, in writing, by the person to which it would otherwise be provided.
(5)A plan shall not be treated as failing to meet the requirements of paragraph (1) merely because notice is provided before the adoption of the plan amendment if no material modification of the amendment occurs before the amendment is adopted.
(f)For purposes of this section—
(1)The term “applicable individual” means, with respect to any plan amendment—
(A)each participant in the plan, and
(B)any beneficiary who is an alternate payee (within the meaning of section 414(p)(8)) under an applicable qualified domestic relations order (within the meaning of section 414(p)(1)(A)),
(2)The term “applicable pension plan” means—
(A)any defined benefit plan described in section 401(a) which includes a trust exempt from tax under section 501(a), or
(B)an individual account plan which is subject to the funding standards of section 412.
(3)A plan amendment which eliminates or reduces any early retirement benefit or retirement-type subsidy (within the meaning of section 411(d)(6)(B)(i)) shall be treated as having the effect of reducing the rate of future benefit accrual.
(g)The Secretary may by regulations allow any notice under subsection (e) to be provided by using new technologies.
