What Is a 457 Plan?

A 457 Plan is a type of non-qualified, tax-advantaged retirement savings plan offered to certain employees of state and local governments, as well as some non-governmental, tax-exempt organizations. These plans are named after Section 457 of the Internal Revenue Code and are designed to help eligible workers defer income and invest for retirement. There are two primary types of 457 plans: 457(b) and 457(f), each with distinct features, eligibility rules, and tax treatments.

Types of 457 Plans

457(b) Plan

The 457(b) Plan is the more common version and is available primarily to employees of state and local governments. Some tax-exempt, non-governmental organizations such as hospitals, charities, and unions may also offer 457(b) plans, though those plans are subject to stricter participation limits and rules. Eligible employees can defer a portion of their salary on a pre-tax basis, reducing their taxable income for the year. The contributions are then invested in options provided by the plan and grow tax-deferred until withdrawal.

Governmental 457(b) plans are typically offered to a wide range of public employees, including teachers, police officers, firefighters, and municipal workers. These plans operate similarly to 401(k) or 403(b) plans but are governed by separate rules.

457(f) Plan

The 457(f) Plan is designed for a narrower group of employees—typically high-ranking executives or key employees at tax-exempt organizations or government entities. Unlike the 457(b), this type of plan allows for contributions beyond the IRS limits. However, the key trade-off is that assets contributed to a 457(f) plan are subject to a "substantial risk of forfeiture," meaning they are not considered vested until the conditions of the agreement are satisfied. Taxation occurs when the risk of forfeiture lapses, not when funds are distributed.

Contribution Limits and Catch-Up Provisions

For 457(b) plans, the annual deferral limit is set by the IRS and adjusts periodically for inflation. As of 2025, the standard contribution limit is $23,500. Participants age 50 or older can contribute an additional $7,500 as a catch-up contribution.

A unique feature of governmental 457(b) plans is the "double limit" catch-up provision. In the three years leading up to normal retirement age, participants may contribute up to twice the annual limit ($47,000 in 2025), provided they have unused deferral capacity from prior years. However, this special catch-up cannot be combined with the age 50 catch-up in the same year.

457(f) plans do not have formal contribution limits, but because contributions are generally taxable once vested, employers structure these plans carefully to align with retention strategies and compensation planning.

Tax Treatment and Distributions

One of the defining characteristics of a 457(b) plan is the tax deferral of both contributions and earnings. Distributions are taxed as ordinary income when withdrawn, but participants are not subject to the 10% early withdrawal penalty that applies to other retirement accounts, such as 401(k)s and IRAs, if they separate from service before age 59½.

This flexibility makes 457(b) plans particularly attractive to employees who may retire early or change jobs. Distributions can begin upon separation from service or at a specified later date chosen by the participant.

In contrast, 457(f) plan distributions are taxed when the substantial risk of forfeiture ends, even if the funds have not been distributed. This makes timing critical for tax planning purposes. Early access or accelerated vesting can trigger significant income tax liability.

Rollovers and Coordination with Other Plans

Governmental 457(b) plans can be rolled over into other qualified plans, such as 401(k)s, 403(b)s, or IRAs, upon separation from service. This offers added flexibility in consolidating retirement assets. However, non-governmental 457(b) plans cannot be rolled into other types of plans. They can only be transferred to another 457(b) plan maintained by a similar non-governmental employer, which limits portability.

457(f) plans are not eligible for rollovers. Once vested, the compensation is treated as ordinary income and is not subject to further tax deferral through qualified plan rollovers.

Participants with access to both a 457(b) and a 403(b) or 401(k) plan can contribute the maximum allowable amount to both plans, effectively doubling their deferral opportunities in a single year. This feature is often utilized by employees of public institutions like universities or hospitals.

Key Regulatory Considerations

Governmental 457(b) plans must be funded and held in trust for the exclusive benefit of participants, providing protection from creditors. In contrast, non-governmental 457(b) and 457(f) plans are considered “unfunded,” meaning the assets are part of the employer’s general assets and are subject to the employer’s creditors. This makes non-governmental plans inherently riskier for participants.

Additionally, non-governmental 457 plans are subject to more complex compliance rules under ERISA and are generally limited to a select group of management or highly compensated employees to avoid violating top-hat plan restrictions.

The Bottom Line

A 457 Plan offers a flexible way for certain public and non-profit employees to save for retirement while benefiting from tax deferral. The 457(b) plan functions similarly to a 401(k), with added early withdrawal advantages and the possibility of contributing alongside other retirement plans. The 457(f) plan, while less common, plays a critical role in executive compensation, offering higher contribution levels but with stricter vesting and tax rules. Understanding the distinctions between these plans is essential for effective retirement planning, particularly in public and nonprofit sectors.
