Educational and Tax Disclosure: This article is provided for general educational purposes only. It does not constitute retirement, investment, tax, legal, financial, employment, or plan-administration advice. State Employee Advisor Network is a marketing and referral platform operated by Revenx LLC. SEAN does not administer 401(k) or 457(b) plans, recommend contribution amounts, select investments, calculate taxes, or provide individualized retirement strategies. Official plan information should come from the employer, plan administrator, IRS, or another authorized source.
A 457(b) and a 401(k) are both employer-sponsored defined-contribution retirement plans.
They can both allow employees to save through payroll deductions, and both may offer:
However, there are important differences involving:
For state and local government employees, the comparison usually involves a governmental 457(b) rather than a nongovernmental 457(b).
That distinction matters because governmental and nongovernmental 457(b) plans do not follow all of the same rules.
A governmental 457(b) is a deferred-compensation plan that may be established by a state or local government employer.
Possible participants may include:
Employees may generally defer part of their compensation into the plan.
Depending on plan design, the 457(b) may offer:
A governmental 457(b) should not be confused with a nongovernmental 457(b), which may be offered by certain tax-exempt organizations and has different asset and rollover rules.
A 401(k) is an employer-sponsored defined-contribution plan commonly associated with private-sector employers.
Employers may include:
Participants may generally contribute through payroll.
Employers may also provide:
A 401(k) account does not promise a specific retirement income amount.
Its eventual value depends on:
Plan terms may be more restrictive than federal limits.
For 2026, the basic employee deferral limit for both plans is:
$24,500
This replaces the live article's outdated 2024 figure of $23,000.
The plan may impose a lower limit.
An employee also cannot contribute more than applicable compensation under the relevant rules.
Governmental 457(b) and most regular 401(k) plans may permit an age-based catch-up for participants age 50 or older.
For 2026, that amount is:
$8,000
This can potentially raise employee deferrals to:
$32,500
when the plan permits the catch-up.
For employees who turn age:
during 2026, the higher catch-up limit is:
$11,250
instead of $8,000.
That can produce a potential employee deferral of:
$35,750
The higher amount replaces the standard catch-up for the applicable age group.
It is not added on top of the $8,000.
Beginning in 2026, certain higher-income participants making age-based catch-up contributions may be required to make those catch-ups as Roth contributions when the plan offers the applicable Roth feature.
For 2026, the IRS uses a prior-year wage threshold of:
$150,000
Employees affected by the rule should confirm how their employer and payroll system administer it.
The special 457(b) final-three-years catch-up is a separate provision.
This is one of the most important distinctions between a governmental 457(b) and a 401(k).
The live article says someone three years from retirement can contribute an extra $3,000.
That is incorrect.
If the plan permits it, a participant may qualify for a special catch-up during the three taxable years ending before the year in which the participant reaches normal retirement age under the plan.
The maximum annual amount is generally the lesser of:
For 2026, twice the $24,500 regular limit would be:
$49,000
But this does not mean everyone using the special catch-up can automatically contribute $49,000.
The amount depends on unused deferral capacity from prior years.
Someone who consistently contributed the maximum may have little or no additional amount available under this provision.
A governmental 457(b) participant who qualifies for both:
generally cannot use both in the same year.
The participant may generally use whichever provision produces the larger allowable deferral.
That is another reason the current article's “extra $3,000” description is misleading.
Yes, when eligible.
This is an important planning difference.
The 457(b) limit is generally separate from the 401(k) elective-deferral limit.
For example, an eligible employee under age 50 could potentially contribute:
$24,500 to a 401(k)
plus
$24,500 to a governmental 457(b)
for a combined ordinary employee deferral of:
$49,000 in 2026
This assumes:
This is different from contributing to both a 401(k) and 403(b), which generally share the same employee elective-deferral limit.
The live article repeatedly calls traditional contributions “tax-free.”
That is inaccurate.
Traditional 401(k) and 457(b) contributions generally reduce current federal taxable income.
Investment earnings generally remain tax-deferred while inside the account.
Taxable distributions are generally included in income when withdrawn.
That is tax deferral, not permanent tax elimination.
A governmental 457(b) or 401(k) may offer designated Roth contributions.
Roth contributions are made with after-tax dollars.
Qualified distributions may generally be tax-free when applicable requirements are satisfied.
Whether traditional or Roth contributions are preferable depends on individual circumstances.
It is too simplistic to say:
Relevant considerations can include:
The live article says both plans generally impose a 10% penalty on early withdrawals.
That is one of its most important errors.
Ordinary distributions from a governmental 457(b) generally are not subject to the federal 10% additional tax on early distributions, even if the participant is under age 59½.
Regular income tax can still apply to pretax amounts.
This can be particularly relevant for someone who leaves public employment before age 59½.
A taxable 401(k) distribution before age 59½ may generally be subject to the 10% additional federal tax unless an exception applies.
Distribution eligibility and tax penalties are separate issues.
The governmental 457(b) rule has an important exception.
If money was previously rolled into the 457(b) from:
that rolled-in amount may remain subject to the early-distribution rules associated with the original plan type.
A participant should therefore not assume every dollar inside a 457(b) automatically receives the same early-withdrawal treatment.
A properly completed eligible rollover generally does not itself create the 10% additional tax.
However, the rollover can affect future withdrawal rules.
Suppose someone leaves government employment at age 55.
If eligible money remains in the governmental 457(b), ordinary distributions generally avoid the federal 10% early-distribution tax.
If the same amount is rolled into an IRA, a later IRA withdrawal before age 59½ may be subject to the 10% additional tax unless another exception applies.
That difference should be considered before automatically rolling over the account.
The 401(k) early-distribution rules also have exceptions.
One important example may apply to certain employees who separate from service during or after the year they reach the applicable age.
This is commonly called the age-55 exception.
Special rules can apply to certain public-safety employees.
This means a 401(k) should not be described as always having a 10% penalty before age 59½.
The exact exception should be verified before taking a distribution.
The live article says employer matching is common in 401(k)s and rare in 457(b)s.
That may occur in some workplaces, but it should not be treated as a universal comparison.
Both plan types may permit employer contributions.
Whether an employer contributes depends on the actual plan.
Possible structures include:
Employees should review the benefit document rather than choose based on an assumption about the plan label.
A 401(k) is subject to a separate annual-additions limit.
For 2026, the general defined-contribution annual-additions limit for a 401(k) is:
$72,000
before age-based catch-up contributions.
This generally includes:
Governmental 457(b) contributions operate under their own statutory annual limit structure.
Employer contributions to a 457(b) generally count toward the 457(b) annual limit rather than being layered on top in the same way as 401(k) employer contributions.
This can materially affect plan design.
Neither plan type automatically has better investment options.
Investment menus depend on:
Possible investments can include:
Compare:
The number of choices alone does not determine whether a plan is better.
Both governmental 457(b) and 401(k) plans may permit participant loans.
Neither plan is required to offer them.
Loan terms may include:
Leaving employment with an outstanding loan may create additional tax or repayment issues.
Use the plan's written loan policy.
The terminology differs between these plan types.
A governmental 457(b) may permit an unforeseeable emergency distribution when federal and plan requirements are satisfied.
A 401(k) may permit a hardship distribution.
These are not identical standards.
Neither should be viewed as a normal source of emergency savings.
Distributions can permanently reduce retirement assets and may create taxable income.
Both plan types can eventually be subject to required minimum distribution rules.
The applicable starting age depends on:
Age 73 applies to many current retirees, but it is not the correct universal RMD age for every participant.
Designated Roth accounts in employer plans generally do not require lifetime RMDs for the original owner under current law.
The live article correctly reflects the current general reduction from the old 50% penalty, but the wording still needs qualification.
A missed RMD can generally result in a:
25% excise tax
on the amount not distributed as required.
That rate may potentially be reduced to:
10%
when the shortfall is corrected within the applicable correction period.
Employees should verify current IRS rules at the time an RMD is due.
The current article combines government and nonprofit 457(b) plans too casually.
That can be misleading.
Generally:
Generally:
A state employee reading this comparison will usually be concerned with the governmental version.
The live article describes a 457(f) as a supplemental 457(b) plan that lets executives contribute more.
That is too simplistic.
A 457(f) is an ineligible deferred-compensation arrangement under a different part of Section 457.
Tax treatment can depend on whether compensation remains subject to a substantial risk of forfeiture.
It should not be presented as merely a high-limit version of a governmental 457(b).
A governmental 457(b) can be especially relevant for an employee expecting to leave government service before age 59½ because ordinary distributions generally avoid the federal 10% additional tax.
A 401(k) may still provide useful early-access exceptions depending on:
This is a planning consideration, not a universal recommendation to favor the 457(b).
A 401(k) may have a valuable employer match.
A governmental 457(b) may also receive employer contributions.
Instead of assuming one is better, compare:
An employer contribution can materially affect the value of the plan.
Readers can review the live article's retained links to the 401(k) financial advisor page and retirement plan consultants.
The related 403(b) vs. 457(b) and 403(b) vs. 401(k) comparisons are also preserved.

A governmental 457(b) and a 401(k) share several retirement-savings features, but they are not interchangeable.
For 2026:
The better fit depends on the actual employer plans, contributions, fees, investment options, retirement timing, and expected need for access.
Neither plan guarantees financial security, investment growth, or a particular retirement income.
The basic annual deferral limit is $24,500.
The basic employee elective-deferral limit is also $24,500.
Yes, when eligible. The governmental 457(b) limit is generally separate from the 401(k) elective-deferral limit.
Ordinary governmental 457(b) distributions generally are not subject to the federal 10% additional tax, although rolled-in money can be treated differently.
During the final three taxable years before normal retirement age under the plan, eligible participants may potentially defer more based on unused prior-year limits.
Generally no. When eligible for both the age-based catch-up and the special final-three-years catch-up, the participant generally uses whichever produces the larger limit.
It may offer useful access after leaving employment before age 59½, but the overall decision also depends on employer contributions, fees, investments, and other resources.
Neither is universally better. Compare the actual plan terms, employer contributions, investment costs, catch-up provisions, and withdrawal rules.
