Retirement Plan Prohibited Transactions

Why ERISA restricts certain transactions

ERISA’s prohibited-transaction rules protect plan assets from dealings that can place a fiduciary or related person on both sides of a transaction. Section 406 generally restricts specified transactions between a plan and a party in interest and separately prohibits fiduciary self-dealing, adverse representation, and receipt of consideration from a party dealing with the plan. These rules apply even when a transaction appears convenient or produces a reasonable price, unless an applicable exemption covers it.

A party in interest can include the employer, a fiduciary, a service provider, certain employees and owners, and specified relatives or entities connected to those people. The exact statutory definition is detailed. For a scenario, identify the relationship to the plan first, then classify the proposed transaction. A routine commercial arrangement can become a prohibited transaction when the other party is related to the plan in a covered way.

The rules are designed to prevent conflicts before they harm participants. A plan’s sale to its sponsor, a loan to a fiduciary, a vendor service contract with a party in interest, or use of plan property for an employer’s benefit may raise section 406 concerns. A fiduciary should not decide that a deal is harmless and proceed without analyzing the statute and possible exemptions.

Section 406(a): dealings with a party in interest

Section 406(a) generally prohibits a fiduciary from causing a plan to engage in certain direct or indirect transactions with a party in interest, when the fiduciary knows or should know the transaction is covered. Categories include a sale, exchange, or lease of property; a loan or extension of credit; furnishing goods, services, or facilities; transferring or using plan assets for a party in interest; and certain acquisition of employer securities or real property.

A plan’s purchase of bookkeeping services from its employer can implicate the services category because the employer is a party in interest. A plan loan to the sponsor can implicate the lending category. A lease of plan-owned office space to a related company can implicate leasing and use-of-assets concerns. Each example requires checking the facts and exemptions; the category signals the need for analysis rather than supplying every conclusion.

The “direct or indirect” language matters. A transaction cannot necessarily avoid the rule because it is routed through an affiliate or intermediary. The fiduciary should identify who ultimately provides the service, receives the asset, or bears the economic benefit. A service provider owned by a plan fiduciary may require a closer conflict and party-in-interest review even when the contract is signed with a separate legal entity.

Section 406(b): fiduciary self-dealing and divided loyalty

Section 406(b) addresses fiduciary conduct involving the fiduciary’s own interest. A fiduciary may not deal with plan assets in the fiduciary’s own interest or for the fiduciary’s own account. A fiduciary may not act for a party whose interests are adverse to the plan or its participants in a transaction involving plan assets. A fiduciary also may not receive personal consideration from a party dealing with the plan in connection with a plan transaction.

For example, a committee member who directs the plan to buy property from the member’s company may be dealing with plan assets for personal benefit. A fiduciary who represents the employer in negotiating a plan transaction while also deciding for the plan may face divided loyalty. A vendor that pays a fiduciary a personal fee for steering plan business creates an obvious concern. Disclosure may be relevant to an exemption, but it does not erase a statutory prohibition by itself.

A fiduciary can be conflicted even if the plan receives a fair price. Section 406(b) focuses on prohibited fiduciary conduct, while prudence asks whether the process and decision served participants. A transaction may raise both questions. A committee should identify conflicts before negotiations, recuse or obtain independent review where appropriate, and determine whether a statutory exemption is available. It should not assume that a conflict disappears because no loss has yet occurred.

Exemptions require their own analysis

ERISA section 408 contains statutory exemptions and authorizes the Department of Labor to grant administrative exemptions under conditions. Some exemptions address specific transactions, such as necessary services at no more than reasonable compensation, loans to participants under qualifying terms, or other defined arrangements. The conditions can be technical and may require independent decision making, disclosures, reasonable terms, and protections for participants. A transaction is exempt only if the actual facts satisfy the applicable requirements.

A general statement that “the fee is reasonable” is not enough if the transaction does not fit an exemption. A service arrangement may need to be necessary, the compensation must be reasonable, and the plan’s fiduciaries must evaluate the arrangement. A participant loan must satisfy plan and statutory terms. An administrative exemption may apply only to specified parties and conduct. Read the current exemption text and any related conditions before relying on it.

Exemptions from one part of the prohibited-transaction rules do not necessarily waive every fiduciary duty. Section 408 states that an exemption does not relieve a fiduciary from other applicable ERISA provisions. A transaction could satisfy an exemption yet still be imprudent, poorly documented, or inconsistent with the plan’s permitted investment objectives. Analyze both transaction legality and the separate duties of loyalty, prudence, diversification, and plan-document compliance.

A worked service-provider example

A 401(k) plan pays a recordkeeper that is a party in interest for administrative services. The committee first recognizes the services transaction may fall within section 406(a). It then determines whether an exemption permits the arrangement, including whether services are necessary and compensation is no more than reasonable. The fiduciaries compare service scope and total compensation with alternatives, consider direct and indirect fees, document the decision, and monitor the provider.

If the recordkeeper also pays a committee member a personal referral fee, the analysis changes. The payment may involve fiduciary self-dealing or receipt of consideration in connection with a plan transaction under section 406(b). Reasonable recordkeeping charges do not automatically excuse the personal payment. The plan should stop and obtain legal review before proceeding. The committee must identify who receives the compensation and whether any exemption covers that specific conduct.

Now suppose the recordkeeper provides the same services at the same total price, but an independent fiduciary makes the selection after comparing alternatives and the committee member discloses the relationship. This may improve governance but is not by itself proof that every exemption condition has been met. The independent fiduciary must have real authority, relevant information, and a process free from improper influence. Disclosure and independent review are tools; the governing exemption and facts control.

Loans, use of assets, and employer transactions

A plan loan to the plan sponsor is a high-risk example because it can be both a credit extension to a party in interest and a use of assets for the sponsor. Participant loans may be permitted under an exemption if they satisfy applicable conditions, but not every loan labeled “participant loan” qualifies. The plan document, amount limits, repayment terms, security, and availability to participants must be reviewed.

Using a conference room, staff time, or equipment owned by the plan can involve plan assets or facilities. If the employer receives a benefit without appropriate payment or a valid exemption, section 406(a) may be implicated. A plan should not reimburse ordinary company expenses from plan assets merely because the employer sponsors the plan. The fiduciary should document the plan’s interest, services received, charges, and legal basis.

Employer securities and real property have separate statutory limits and exemptions. ERISA does not allow unrestricted investment in the sponsor simply because participants recognize the company. The fiduciary should check the employer-security rules, diversification requirements, plan design, and applicable exemptions. A plan’s ability to hold employer stock in a particular circumstance does not eliminate the need for prudent selection and monitoring.

QDIA status does not provide a prohibited-transaction exemption

A qualified default investment alternative provides limited relief from certain fiduciary liability for losses in default investment circumstances when the regulation’s conditions are satisfied. It does not relieve ERISA section 406 prohibited-transaction liability. A plan that defaults participants into a fund managed by a related party must analyze the relationship and any applicable exemption separately. A valid QDIA category does not make conflicted compensation or self-dealing permissible.

This distinction is easy to test. The QDIA rule concerns the default investment and specified fiduciary-loss relief. Section 406 concerns transactions and fiduciary conflicts. A committee should satisfy both regimes where both apply. If the fund provider is a party in interest, review compensation, services, disclosures, and exemption conditions even if the investment is a permitted target-date or balanced fund.

What happens when a transaction is prohibited

A prohibited transaction can lead to restoration of plan losses, disgorgement of profits, excise taxes under the Internal Revenue Code, and other civil or remedial consequences depending on the parties and facts. Fiduciary status can carry personal liability for losses resulting from a breach. The exact remedy is statutory and fact-specific. Prompt correction may matter under some rules, but a fiduciary should obtain qualified legal and tax advice rather than assume an after-the-fact correction removes liability.

A plan committee should have a process for identifying parties in interest, reviewing contracts, collecting compensation disclosures, recording conflicts, and checking exemptions before execution. If a concern is discovered, preserve records and stop further activity as appropriate while counsel evaluates correction. Do not destroy communications or characterize a transaction as exempt before the required analysis is complete.

A disciplined scenario method

For a question, name the plan, identify the counterparty, and decide whether that person or entity is a party in interest. Classify the transaction: property sale or lease, credit, service, transfer or use of assets, or a fiduciary’s own-interest conduct. Then check for a precise statutory or administrative exemption and its conditions. Finally, ask whether the fiduciary also met the separate duties of loyalty and prudence.

Suppose a pension plan leases its building to the employer at an asserted market rent. The employer is a party in interest, and the lease can fall within the statutory category. The next question is whether an exemption applies and whether its conditions are met. Market rent alone does not settle the issue. The fiduciary must also evaluate the plan’s interest and comply with any applicable fiduciary duties.

A related service provider can present a different scenario. The plan’s contract may involve necessary services, reasonable compensation, and a statutory exemption, yet a fiduciary who personally receives a referral payment may still violate section 406(b). Separate the transaction-level exemption from individual fiduciary conduct. That distinction helps avoid the common answer that a disclosed conflict or fair market price automatically cures every concern.

If a plan pays an affiliate, the fiduciary should map the full payment flow rather than review only the signed invoice. Revenue sharing, referral payments, and bundled fees can reveal indirect compensation. Review those details before approving an arrangement, then confirm whether an exemption covers the actual recipient and service.

When facts are uncertain, pause the transaction and seek counsel before assets move. An early review can identify whether an exemption is available and what safeguards it requires.

Counsel can help identify and document the required corrective steps.
