457(f) Plan

What Is a 457(f) Plan?

A 457(f) plan is an ineligible deferred-compensation arrangement used by certain tax-exempt and governmental employers for select employees, often senior executives. Unlike an eligible 457(b) plan, a 457(f) plan does not mainly function as a standard broad-based workplace retirement account. Its defining feature is that the deferred compensation generally becomes taxable when it is no longer subject to a substantial risk of forfeiture.

Readers sometimes assume every 457 plan works like a normal salary-deferral retirement plan. A 457(f) plan is different. The central planning issue is usually vesting and tax timing, not just long-term retirement accumulation.

Key Takeaways

• A 457(f) plan is an ineligible deferred-compensation arrangement under section 457(f).
• It is commonly associated with select employees of tax-exempt or governmental employers.
• The tax trigger is usually when the compensation is no longer subject to a substantial risk of forfeiture.
• A 457(f) plan is not the same thing as the broader 457 plan category or an eligible 457(b) plan.
• Vesting terms often matter more than annual contribution mechanics.

How a 457(f) Plan Works

An employer promises compensation to be paid later, often subject to continued employment or other vesting conditions. While that forfeiture condition remains in place, the compensation may continue to receive deferred treatment. Once the condition lapses, the deferred amount generally becomes includible in income even if the employee does not receive cash immediately.

The account is usually analyzed through tax timing rather than only retirement savings language. The key question is when the compensation ceases to be forfeitable and what that means for the participant's taxable income.

How 457(f) Differs From 457(b)

A 457(b) plan is the eligible version most readers think of when they hear 457 in a workplace-retirement context. A 457(f) plan is the ineligible version, and that difference changes the planning problem materially. The 457(b) conversation usually centers on deferral limits, withdrawals, and retirement use. The 457(f) conversation usually centers on compensation design, vesting, and when income becomes taxable.

The two terms should not be collapsed into one page. The labels may look adjacent in the tax code, but they answer different real-world questions.

Example Vesting Date Creating the Tax Trigger

Suppose a tax-exempt hospital promises a senior executive deferred compensation that will vest only after five more years of service. While the executive is still exposed to losing the benefit, the plan may remain subject to the forfeiture condition. Once that condition ends, the deferred amount generally becomes taxable even if the executive has not yet received the full cash payout.

This example is the core of the term. The useful lesson is not a current-year dollar limit. It is that the timing of vesting can drive the tax event.

How a 457(f) Changes Vesting and Tax Timing

A 457(f) plan can create concentrated taxable income at vesting and can affect cash-flow planning, withholding expectations, and overall retirement or executive-compensation strategy. That makes it materially different from a broad employee retirement plan meant mainly to collect payroll deferrals over decades.

Readers encountering the term should think first about forfeiture conditions, vesting, and when deferred compensation turns into taxable compensation. That is the practical center of the concept.

The Bottom Line

A 457(f) plan is an ineligible deferred-compensation arrangement whose tax treatment usually turns on when the compensation is no longer subject to a substantial risk of forfeiture. It is better understood as a vesting-and-tax-timing concept than as a standard workplace retirement account.
