457(b) Deferred Compensation Plan

A 457(b) plan is a deferred compensation plan offered by state and local governments and eligible nonprofits, allowing employees to defer income and withdraw it in retirement without the 10% early-withdrawal penalty that applies to 401(k)s and IRAs. The lack of penalty makes 457(b) plans unusual and strategically valuable for pre-retirement Roth conversions.

The no-penalty plan for public servants

A 457(b) is exclusively for government and nonprofit employees. State highway departments, city water authorities, county schools, university staff, and qualifying nonprofits can offer one. The IRS carved out 457(b)s to give public servants a savings vehicle that would not penalize early withdrawals—the assumption being that public employees often stay in the workforce into their 60s and need funds between retirement and Social Security.

The critical difference from a 401(k) or traditional IRA is the penalty structure. If you withdraw from a 401(k) before 59½, you owe 10% early-withdrawal penalty plus ordinary income tax. A 457(b) withdrawal, regardless of age, incurs only ordinary income tax. No penalty. This is the plan’s defining feature and the reason many public employees prioritize it.

How the no-penalty withdrawal works

Once you have separated from service (retired, left the job), you can withdraw from your 457(b) and pay ordinary income tax at your marginal rate—nothing more. The IRS does not punish early access. This is not a loophole; it is by design. The reasoning was that government employees might retire at 55 or 60 and live on the plan until 62 or 65, when Social Security or pension income kicks in.

Contrast this with a 401(k): withdraw at 55, and you owe the 10% penalty plus income tax (about 37% total in a higher bracket). The 457(b) avoids that haircut. Over a decades-long retirement, this tax savings can compound significantly.

The penalty forgiveness applies only after separation from service. While you are working, the same 10% penalty applies if you access the funds before 59½ (with exceptions). Once you leave, the gates open.

Contribution limits: you can max out two separate plans

A 457(b) has its own $23,500 annual limit (as of 2024). Here is the unusual part: if you also have access to a 403(b) or 401(k) through the same employer, the limits are separate. Many government employers offer both—a 403(b) for school employees and a 457(b) for administrative staff, or a 401(k) and a 457(b).

You can contribute the full $23,500 to your 457(b) and the full $23,500 to your 403(b) in the same year. This is called “stacking” and is legal. The aggregate limit across all plans is the combined total—$47,000 if you max both. This doubles your tax-deferred savings capacity, making 457(b)s extraordinarily powerful for savers.

At age 50, the catch-up allowance is $7,500 per plan, so the total could reach $61,000 annually (with an additional $3,000 if you qualify for the 403(b) or 457(b) “extra” catch-up for 15+ years of service).

Roth conversions are tax-efficient with a 457(b)

This is where 457(b) strategy gets sophisticated. Suppose you retire early at 55, before Social Security or Medicare. You have a 401(k) balance of $200,000 and a 457(b) balance of $150,000. You want to live on your savings and make Roth conversions in low-income years to build a tax-free nest egg for the future.

If you draw $40,000 from the 457(b) to live on, it counts as ordinary income and likely keeps you in a low bracket (say, 12%). You can then convert $100,000 from your 401(k) to a Roth IRA in the same year and stay in that 12% bracket. The Roth conversion incurs no additional penalty.

Compare this to a retiree with only a 401(k). Drawing from the 401(k) before 59½ triggers the 10% penalty plus income tax—a brutal tax hit that discourages large conversions. The 457(b)’s penalty-free withdrawals let you carefully manage your taxable income, take what you need penalty-free, and convert larger amounts to Roth accounts at low tax rates.

Many financial advisers recommend this strategy for government workers retiring before 59½: live on the 457(b), convert the 401(k) or IRA to Roth accounts, repeat for several years, then switch to Social Security or 403(b) distributions once RMDs begin at 73.

Vesting and employer match work like 401(k)s

Your own contributions vest immediately. The employer’s match or non-elective contribution vests per the plan document, typically over 3–5 years for government employers (some use immediate vesting). When you leave, you can roll vested balances to an IRA or—if the new employer offers a 457(b), 403(b), or 401(k)—roll it there.

Required Minimum Distributions: triggered by separation

Unlike a 401(k), where RMDs begin at 73 regardless of employment status, a 457(b) RMD is triggered by separation from service or age 73, whichever comes first. If you leave your government job at 55, RMDs begin on the April 1 after that year (not 18 years later at 73). This prevents indefinite deferral and is a concession to the plan’s no-penalty structure.

You can mitigate this by rolling the 457(b) to an IRA after separation. Once in an IRA, RMDs follow standard IRA rules (begin at 73, based on life expectancy).

Loans and restrictions vary by plan type

Governmental 457(b)s (offered by state and local government employers) may allow loans; non-governmental 457(b)s (some nonprofits) usually do not. Rules are tighter than 401(k)s. If a loan is available, the limit is often 50% of your vested balance, capped at $50,000, similar to 401(k) rules.

Some plans allow withdrawals for “unforeseeable emergencies”—a vague standard that depends on the plan administrator. Get specifics in writing before assuming you can access funds early in a pinch.

Who should prioritize a 457(b)

Government workers and eligible nonprofit staff should max out a 457(b) before a 403(b), especially if they plan to retire before 59½. The no-penalty withdrawal and ability to stack with other plans make it a cornerstone of early-retirement planning. Teachers with a 403(b) option often overlook the 457(b) available through the school district—a missed opportunity.

If your employer offers both a 457(b) and a 403(b), prioritize the 457(b) to age 59½, then the 403(b). Once you turn 59½, both are equally accessible, so max both for the highest tax deferral.
