457(b) Plans: Rules, Roth 457, and Withdrawal Quirks

457(b) plans are deferred compensation plans common among government and nonprofit employers. They’re especially valuable because contributions don’t count against your 401(k)/403(b) limit—and they often avoid early withdrawal penalties. Compare plan design with 403(b) vs 401(k).

Key Takeaways

• 457(b) contributions do not reduce your 401(k)/403(b) contribution room.
• Governmental 457(b) withdrawals avoid the 10% early penalty after separation.
• Many plans now offer Roth 457 contributions for tax-free growth.

Why 457(b) Plans Are Unique

Double Your Tax-Advantaged Savings

Unlike 401(k) and 403(b) plans which share contribution limits, 457(b) has its own separate limit. If you have access to both:

Example (2025, under 50):

• 401(k) or 403(b): $23,500
• 457(b): $23,500
• Total: $47,000 in elective deferrals

That’s nearly double what most workers can save in tax-advantaged accounts.

No 10% Early Withdrawal Penalty

Governmental 457(b) plans have a key advantage: no 10% early withdrawal penalty after you separate from service, regardless of age.

• Leave your job at 45? Take 457(b) distributions without penalty.
• This makes 457(b) ideal for early retirement planning.

Note: This benefit applies to governmental plans only. Non-governmental (private nonprofit) 457(b) plans have different rules.

457(b) Contribution Limits (2025 vs 2026)

Special 457(b) Catch-Up: Final 3 Years

457(b) plans have a unique catch-up provision in the three years before normal retirement age:

• You can contribute up to double the regular limit (e.g., $47,000 in 2025)
• This is instead of (not in addition to) the age-50 catch-up
• “Normal retirement age” is defined by your plan

Example: If your plan’s normal retirement age is 65 and you’re 63 in 2025:

• You could contribute up to $47,000 (double the $23,500 limit)
• This is higher than the standard 50+ catch-up of $31,000

Roth 457: Tax-Free Growth Option

Many governmental 457(b) plans now offer Roth contributions, giving you the choice:

Feature	Traditional 457	Roth 457
Tax on contributions	Pre-tax (deductible)	After-tax
Tax on growth	Tax-deferred	Tax-free
Tax on withdrawals	Ordinary income	Tax-free (if qualified)
Best for	Higher current bracket	Lower current bracket, or tax diversification

Roth 457 Qualification Rules

For tax-free Roth 457 withdrawals:

• Account must be open for 5 years, AND
• You must be 59½ or older (or disabled/deceased)

The 5-year clock starts January 1 of the year of your first Roth contribution.

Traditional vs Roth 457: How to Choose

• Choose Traditional if your current tax rate is high and you expect lower taxes in retirement
• Choose Roth 457 if your current rate is low or you want tax diversification
• Split contributions if you’re uncertain

See our guide: Roth vs Traditional Tax Tradeoffs. It helps to compare against your marginal tax rate and effective tax rate.

Governmental vs Non-Governmental 457(b)

Governmental 457(b) (state/local government):

• Assets held in trust for employees
• Can roll over to IRA, 401(k), etc.
• No 10% early withdrawal penalty after separation
• Roth option increasingly available

Non-Governmental 457(b) (private nonprofits):

• Assets remain property of the employer
• Subject to employer’s creditors (credit risk!)
• Cannot roll over to IRA (except to another 457(b))
• More restrictive distribution rules
• Less common Roth option

Important: If you work for a private nonprofit, understand that your 457(b) balance is at risk if your employer has financial trouble.

Withdrawal Rules

Governmental 457(b) Distributions

You can take distributions:

• After separation from service (any age, no penalty)
• At age 59½ (even if still employed)
• For unforeseeable emergencies
• After death or disability

No 10% penalty on governmental 457(b) distributions (ever), but you do owe income tax on traditional balances.

Non-Governmental 457(b) Distributions

More restrictive:

• Generally only after separation, death, disability, or emergency
• Cannot roll to IRA
• May be subject to employer’s creditors

457(b) Rollovers

Governmental 457(b) can roll to:

• Traditional IRA
• Roth IRA (taxable conversion)
• 401(k), 403(b), or another governmental 457(b)

Non-Governmental 457(b) can roll to:

• Another non-governmental 457(b) only

Tip: If you roll a governmental 457(b) to a 401(k) or IRA, you may lose the early withdrawal penalty exemption. Consider keeping it in a 457(b) if you might need early access.

Required Minimum Distributions (RMDs)

457(b) plans follow the same RMD rules as 401(k)s:

• Begin at age 73 (for those born 1951-1959)
• Begin at age 75 (for those born 1960+)
• Can delay if still working for that employer (governmental plans)
