Reasonable interest rate on plan loans

“What interest rate should a plan apply as part of its plan loan program?”

ERISA consultants at the Retirement Learning Center Resource Desk regularly receive calls from financial advisors on a broad array of technical topics related to IRAs, qualified retirement plans and other types of retirement savings plans. We bring Case of the Week to you to highlight the most relevant topics affecting your business. A recent call with a financial advisor from Ohio is representative of a common inquiry related to 401(k) plan loans.

Highlights of Discussion

Loans to 401(k) plan participants are generally prohibited unless they

The Department of Labor (DOL) gives us a guideline for what is reasonable, but with room for interpretation. According to DOL Reg. § 2550.408b-1(e) [1], a plan’s loan interest rate is reasonable if it is equal to commercial lending interest rates under similar circumstances (see also DOL Advisory Opinion 81-12A). In an example, the DOL explained, “The trustees, prior to making the loan, contacted two local banks to determine under what terms the banks would make a similar loan taking into account the plan participant’s creditworthiness and the collateral offered.”

The IRS has similar requirements in order for a plan loan to avoid excise tax under Internal Revenue Code Section (IRC §) 4795(c) and (d)(1) [2] for prohibited transactions. In a September 12, 2011 IRS phone forum [3], IRS personnel stated informally: “… as a general rule the Service generally considers prime plus 2% as a reasonable interest rate for participant loans.”

The prime rate is an interest rate determined by individual banks, and is often based on a review of the Federal Reserve Boards’ H.15 Selected Interest Rates [4] release of prime rates posted by the majority of the largest 25 banks in the U.S.  Prime is often used as a reference rate (also called the base rate) for many types of loans.[1] [5] Conceivably, adding one or two percentage points to the prime rate makes the interest rate charged to a participant more consistent with general consumer rates, as individuals can rarely get a loan at the going prime rate.

In its Winter 2012 publication, “Retirement News for Employers,” [6] the IRS suggests asking the following questions to determine if a loan interest rate meets the reasonable standard:

According to Internal Revenue Manuals, Part 4, Section 4.72.11.4.2.1.1, IRS examination steps related to verifying a reasonable rate of interest include

On the second point above, even if the interest rate on the loans is reasonable, the overall rate of return might be unreasonable. This could occur if it is determined that a plan’s substantial investment in participant loans is causing the overall rate of return to be materially less than what could have been earned in other investment options under the plan. The DOL has opined that a participant loan as an investment would not be prudent if it provided the plan with less return, relative to risk, than comparable investments available to the plan.

Conclusion

Determining reasonableness is a question of fact and circumstances, and there is no DOL or IRS “safe harbor” rate. Plan sponsors’ must 1) take into consideration relevant current market conditions, and 2) conduct periodic reviews of the interest rate to ensure it continues to reflect current market conditions. Anytime a participant loan is refinanced, the interest rate should be reviewed and updated, if needed. Above all, plan sponsors must be able to document the process they used to determine reasonable interest rates for participant loans in order justify their selection.
