Key Takeaways

Nonprofit 457 plans require careful oversight because compliance errors can create significant tax consequences for participants.
457(b) and 457(f) plans serve different purposes and follow different tax, contribution, distribution, and reporting rules.
Common compliance risks include eligibility issues, contribution limit failures, payroll tax reporting errors, missed top hat filings, and outdated plan documents.
A periodic 457 plan review can help nonprofits identify and address issues before they become more costly.

Why Nonprofit 457 Plan Compliance Matters

The world of qualified plans has been busy with the implementation of SECURE 1.0 and SECURE 2.0, along with a new fiduciary definition from the Department of Labor (“DOL”). Meanwhile, there has been a notable lack of major developments in the nonprofit Internal Revenue Code (“Code”) section (457 plan) 457 plan sector.

Although 457 plans have not faced significant legislative changes like 401(k) plans, compliance with existing rules is crucial because operational errors typically cannot be corrected under the IRS's Employee Plans Compliance Resolution System (EPCRS). If an “eligible” 457(b) plan becomes “ineligible”, it may be classified as a 457(f) plan per regulations. This reclassification could lead to violations of the more complex requirements of Code section 457(f) and potentially violate Code section 409A, resulting in severe tax penalties for affected participants.

457(b) vs. 457(f) Plans for Nonprofit Organizations

The main distinction between a 457(b) plan and a 457(f) plan is their purpose. A 457(b) plan is an "eligible" plan designed to supplement retirement savings within specified contribution limits. In contrast, a 457(f) plan is an "ineligible" executive retention tool with no contribution limits, but it carries a high risk of asset forfeiture. Both plans are classified as nonqualified deferred compensation vehicles governed by section 457 of the Code. To meet the retirement plan requirements of ERISA, eligibility must be restricted to a select group of highly compensated employees, managers, officers, or executives, excluding "rank-and-file" employees.

Below is a chart highlighting some differences between the two types of 457 nonqualified deferred compensation plans for nonprofit entities.

	457(b) Plans	457(f) Plans
Authority	Plans that meet the requirements of the Internal Revenue Code (“IRC”) §457(b)	Plans that do not satisfy one or more statutory requirements applicable to 457(b) plans
Participation	Participation is limited to a select group of management or highly compensated employees	Same
Funding	Plans must be unfunded; benefits are paid from the employer's general assets and are subject to creditors	Same
Contribution Limits	Contributions are subject to an aggregate annual limit ($24,500 for 2026)	Not limited to a specific dollar amount
Nondiscrimination Requirements	No	No
Distribution Restrictions	Distributions are generally not permitted until the earlier of severance from employment or age 72, with exceptions for "unforeseeable emergencies" and other limited cases	See below for information regarding the application of IRC §409A
Tax-Free Rollover Eligibility	No	No
Required Minimum Distribution (RMD) Rules	Yes	No
Taxation of Benefits	Benefits are generally taxed when paid or "otherwise made available" to the participant (i.e., the earliest date on which the plan allows distributions to commence after severance from employment). Plans may allow participants to elect to defer payment and taxation of benefits beyond that date in certain circumstances	Benefits are taxable as soon as they are no longer subject to "a substantial risk of forfeiture" (e.g., once vested), even if not yet distributed. An example of a substantial risk of forfeiture would be a requirement that the participant work a certain number of years before becoming entitled to receive the benefit
IRC §409A Rules on Nonqualified Deferred Compensation	No	Yes, but most plans will be structured to be exempt from the extensive rules of §409A regarding elections, distributions, and forms of payment
IRS Reporting	Reported on Form W-2 and Form 990 when paid	Reported on Form W-2 and Form 990, once subject to taxation
DOL Reporting Requirements	Exempt from annual Form 5500 filing requirements, but an initial “top hat” notice must be filed with the Department of Labor (DOL) when the plan is established	Same

The IRS identifies the following common compliance issues related to 457 plans:

Failing to adhere to the provisions outlined in the plan agreement

Failing to update plan documents as needed

How Nonprofits Can Strengthen 457 Plan Compliance

The longer compliance issues with a plan remain unresolved, the more serious the organizational and financial consequences may become. Therefore, we recommend conducting a thorough review of your 457 plans as a prudent step. If any compliance issues are identified during the review process, remedies may be available to address them.
