What Are the Section 412 Minimum Funding Standards?

A defined benefit pension plan represents a promise from an employer to its employees, guaranteeing a specific monthly income upon retirement. This security depends on the employer’s ability to make good on its promises in the future. To ensure these commitments are met, federal law establishes a framework of funding rules. These regulations, found within the Internal Revenue Code (IRC), mandate that employers systematically set aside funds over time, preventing a situation where a plan is unable to pay the benefits that employees have earned.

Core Funding Requirements

At the heart of the federal funding rules under IRC Section 412 is the requirement for an employer to make a “Minimum Required Contribution” (MRC) to its pension plan each year. This annual contribution is composed of distinct parts calculated by an actuary. The two primary components are the plan’s Target Normal Cost and any amounts needed to pay down unfunded liabilities.

The Target Normal Cost represents the value of pension benefits that employees earned during the current year. The second component relates to the plan’s overall health, measured by its Funding Target, which is the total present value of all benefits earned by all employees and retirees to date. Think of the Funding Target as the total mortgage on a house, while the Target Normal Cost is the interest that accrued this month.

If a plan’s assets are less than its Funding Target, a shortfall exists, and payments to amortize that shortfall are added to the Target Normal Cost to determine the total MRC. The calculations involve complex actuarial assumptions about factors like employee turnover, life expectancy, and future investment returns.

Addressing Funding Shortfalls

When a pension plan’s assets fall below its Funding Target, a funding shortfall is created. This can arise from factors like lower-than-expected investment returns or changes in actuarial assumptions. The law does not require the employer to immediately contribute the entire deficit in a single lump sum, instead providing a structured mechanism to correct the shortfall over a manageable period.

This correction process is known as amortization. The total shortfall amount is divided into installment payments that must be paid over a 15-year timeframe. These annual amortization payments become a required part of the plan’s Minimum Required Contribution. By spreading the shortfall payments over 15 years, the rules make the obligation less burdensome for the employer in any single year. This approach allows a company to continue its business operations without a sudden, massive cash outflow while ensuring the plan’s financial health is steadily restored.

Consequences of Underfunding

Failing to make the full Minimum Required Contribution by the specified deadlines results in an “accumulated funding deficiency.” This triggers significant financial penalties for the employer, which are imposed under IRC Section 4971. The consequences are applied through a two-tiered excise tax system.

The first-tier tax is an automatic penalty of 10% of the accumulated funding deficiency. This tax is imposed directly on the employer for the taxable year in which the failure occurs. It is a non-deductible excise tax, meaning the employer cannot claim it as a business expense to reduce its income tax.

If the funding deficiency is not corrected within a specified “taxable period,” a second-tier tax is imposed. This additional tax is 100% of the remaining uncorrected funding deficiency. The taxable period generally ends when the IRS mails a notice of deficiency regarding the initial 10% tax, giving the employer a window to correct the shortfall and avoid the much larger penalty.

Applying for a Funding Waiver

An employer facing significant financial distress may be able to obtain a temporary reprieve from its funding obligations through a waiver from the IRS. To qualify, the employer must demonstrate that it is experiencing a “substantial business hardship” and that forcing it to make the contribution would be detrimental to the interests of the plan participants.

Preparing a waiver request requires extensive documentation. The employer must provide detailed financial information to the IRS to substantiate its claim of hardship, which could include several years of financial statements, evidence of operating losses, and recovery projections. The application must also include a notice that has been provided to all affected parties, such as plan participants and retirees.

This package is submitted with the plan’s annual reporting on Form 5500. The IRS will not grant a waiver for more than three out of any 15 consecutive years. If approved, the waived amount does not disappear; instead, it is amortized and paid back to the plan over five years.
