A 401(k) and a governmental 457(b) can look almost identical on a benefits website.
Both can let you save money from your paycheck. Both can offer pre-tax contributions. Governmental 457(b) plans can also offer Roth contributions. Both can have investment menus and annual limits.
But two differences make a 457(b) especially interesting:
- Its annual deferral limit is generally separate from the 401(k)/403(b) elective-deferral limit.
- Distributions from a governmental 457(b) are generally not subject to the 10% early-distribution tax, except for certain amounts rolled into the plan from other account types.
Quick answer:** If your employer offers both a 401(k) and governmental 457(b), you may be able to contribute up to the annual limit in each plan. For 2026, the basic limit is $24,500 for each. The 457(b)'s early-distribution rules can also be more flexible after you leave the employer. The better plan to fund first still depends on employer match, fees and investments.
Important: this guide focuses on governmental 457(b) plans
This distinction matters.
State and local governments can sponsor governmental 457(b) plans. Certain tax-exempt organizations can sponsor nongovernmental 457(b) plans for select employees.
The rules are not the same.
Nongovernmental 457(b) plans have different funding, creditor, rollover and catch-up issues. If you work for a nonprofit and your plan says “top hat” or nongovernmental 457(b), do not apply every governmental rule in this article to your account.
The IRS has a separate page explaining nongovernmental 457(b) plans ↗.
401(k) vs. governmental 457(b) at a glance
| Feature | 401(k) | Governmental 457(b) |
|---|---|---|
| Common employers | Private-sector employers | State/local governments and public entities |
| 2026 basic employee limit | $24,500 | $24,500 |
| Limit shared with the other plan? | 401(k) deferrals generally coordinate with 403(b) deferrals | 457(b) has a separate limit |
| Age-50 catch-up | Can be offered | Can be offered |
| Special age 60–63 catch-up | Applies under current rules where permitted | Applies to governmental 457(b) where permitted |
| Special final-3-years catch-up | No | 457(b) can offer a separate special catch-up |
| 10% early-distribution tax after leaving | Generally applies before 59½ unless exception | Generally does not apply to governmental 457(b) distributions, except certain rollover-source money |
| Roth option | Can be offered | Governmental plan can offer |
| Employer contributions | Possible | Possible, but count within 457(b) annual limit rules differently than a 401(k)'s separate employer additions framework |
Can you contribute to both a 401(k) and a 457(b)?
Yes, if you are eligible for both and the plans allow the contributions.
This is one of the most useful features for workers with access to both plans.
The IRS explains that the 457(b) deferral limit is separate from the limit that applies to 401(k) and 403(b) elective deferrals. Its page on workers eligible for more than one retirement plan ↗ gives examples.
For 2026, the basic limits mean someone under 50 with enough eligible pay and both plans available could potentially contribute:
- $24,500 to the 401(k), plus
- $24,500 to the governmental 457(b)
Total employee deferrals: $49,000
That is a huge difference from having two 401(k)-type jobs where the employee elective-deferral limit generally must be coordinated across plans.
2026 contribution limits
The IRS set the 2026 basic elective-deferral limit at $24,500 for 401(k), 403(b) and governmental 457 plans.
Eligible workers age 50 and older can generally use an $8,000 catch-up in plans that permit it.
Under SECURE 2.0, a higher catch-up applies for eligible workers who turn ages 60, 61, 62 or 63 during the year. For 2026, that higher catch-up is $11,250.
See the IRS 2026 retirement limits announcement ↗.
The special 457(b) catch-up can be very powerful
A 457(b) has another catch-up rule that can apply during the final three taxable years before the plan's normal retirement age.
If the plan offers it and you have unused deferral room from earlier eligible years, the special catch-up can allow a higher contribution—potentially up to twice the basic annual limit, subject to the detailed calculation.
The IRS explains the rule in its 457 plan catch-up guidance ↗.
For a governmental 457(b), you generally cannot use the age-50 catch-up and the special final-three-years catch-up in the same year. You use the one that allows the larger contribution.
This is a plan-administrator calculation. Do not simply double your payroll contribution because you are three years from retirement.
The biggest withdrawal difference: the 10% additional tax
This is where a governmental 457(b) can be much more flexible.
The IRS states that distributions from a governmental 457(b) generally are not subject to the 10% additional tax on early distributions, except for distributions attributable to certain rollover money that came from another plan or IRA.
That means someone who retires or leaves public employment at 52 may be able to take taxable distributions from the governmental 457(b) without the 10% additional tax that often applies to an early 401(k) distribution.
Regular income tax can still apply to pre-tax 457(b) money.
The IRS spells out the distinction in its early-distribution exception guidance ↗.
Example: retiring from public service at 52
Assume Jordan retires from a county job at age 52 with:
- $300,000 in a governmental 457(b)
- $250,000 in a 401(k)-type plan from an older private-sector employer
Jordan needs $25,000 a year before reaching 59½.
A distribution from the governmental 457(b) can have a different early-tax result from a distribution from the old 401(k).
That difference may make the 457(b) a useful bridge account for early retirement.
This is also why blindly rolling every old retirement account into one IRA can remove useful plan-specific withdrawal features.
What if you roll 401(k) money into the 457(b)?
Be careful.
The special no-10%-additional-tax treatment for governmental 457(b) distributions generally does not magically cleanse rollover money that came from an account subject to the early-distribution tax.
Plans track rollover sources.
If early retirement is part of your strategy, ask the 457(b) administrator how rollover-source money is tracked and distributed before consolidating accounts.
Which plan should you fund first?
If you have both, use this order.
1. Get the full employer match
If the 401(k) matches and the 457(b) does not, the 401(k) may deserve the first dollars even if you love the 457(b)'s withdrawal rules.
Employer money is part of compensation.
2. Compare fees and investments
A 457(b) can have great investments or poor ones. Same with a 401(k).
Compare the funds you would actually own and the fees you would actually pay.
3. Consider your retirement age
If you are a public employee who may retire in your early 50s, the governmental 457(b)'s early-distribution treatment can be unusually valuable.
4. Use both if your savings goal is high
Workers who want to save well above the single-plan limit may be able to use both accounts.
Does a 457(b) have an employer match?
It can have employer contributions, but the mechanics differ from a 401(k).
In a 401(k), employer contributions are generally on top of the employee elective-deferral limit, subject to the plan's overall annual-additions limit.
In a 457(b), employer contributions can count toward the 457 annual limit.
So a headline “5% employer contribution” should not be evaluated without understanding how the plan counts it.
Ask the administrator:
- Does the employer contribute to the 457(b)?
- Is it matching or nonelective?
- Does that amount reduce how much I can defer under the 457 limit?
- Is there a separate 401(k), 401(a) or pension contribution?
Public-sector benefit packages often combine several plan types.
Roth 401(k) vs. Roth 457(b)
Governmental 457(b) plans can offer designated Roth accounts.
If both plans offer Roth, the same broad tax choice exists: pay tax on the contribution now, then aim for tax-free qualified distributions later.
But the contribution limits remain plan-specific, and withdrawal rules can still differ by source and plan.

How 401(k) Plan Report fits this comparison
401(k) Plan Report is built around public Form 5500 data, which is especially useful for private employer retirement plans.
Governmental plans are not always reported through the same Form 5500 system in the same way. That means coverage can be uneven for public-sector 457(b) plans.
We should not pretend the database sees a plan it does not have.
Coverage matters:** Search the employer. If the governmental 457(b) is not in the Form 5500 data, use the public employer's official plan documents instead.
401(k) vs. 457(b) for a teacher, police officer or local-government worker
These workers may have more than one retirement benefit:
- A pension
- A 457(b)
- A 401(k), 401(a) or 403(b)
The pension may provide formula-based retirement income. The 457(b) can provide flexible defined-contribution savings. A second workplace plan can add more savings room or employer contributions.
Do not evaluate the 457(b) in isolation. Map the entire package.
Our 401(k) vs. pension guide can help with the defined-benefit side.
Common 457(b) mistakes
Mistake 1: Assuming the 401(k) and 457(b) share one $24,500 limit
They generally have separate deferral limits.
Mistake 2: Assuming all 457(b)s are governmental
Nongovernmental 457(b) plans have important differences.
Mistake 3: Assuming all 457(b) money is penalty-free forever
Rollover-source money can retain different early-distribution treatment.
Mistake 4: Using both 457 catch-ups in the same year
The governmental age-50 catch-up and special final-three-years catch-up generally cannot both be used in the same year.
Mistake 5: Ignoring employer contributions when calculating the 457 limit
457(b) contribution counting is not identical to a 401(k).
A practical decision checklist
If you have both plans, write down:
- [ ] Exact 401(k) employer match
- [ ] Exact 457(b) employer contribution, if any
- [ ] 401(k) fund fees
- [ ] 457(b) fund fees
- [ ] Whether each offers Roth
- [ ] Whether you expect to leave public employment before 59½
- [ ] Whether you are eligible for either catch-up
- [ ] Whether you can afford to use both annual limits
Then choose the order that gives you the most employer money and the best combination of low costs and useful withdrawal rules.
Frequently asked questions
Can I max a 401(k) and 457(b) in the same year?
Potentially yes. The 457(b) limit is separate from the elective-deferral limit coordinated across 401(k) and 403(b) plans. You still need enough eligible compensation and both plans must allow the contributions.
Is a 457(b) better than a 401(k)?
Not automatically. A governmental 457(b) has a major early-withdrawal advantage, but a 401(k) may have a better employer match, investment menu or fees.
Can I take 457(b) money before 59½ without the 10% tax?
Governmental 457(b) distributions generally are not subject to the 10% additional tax, except for certain amounts attributable to rollovers from plans or IRAs that were subject to the tax. Regular income tax may still apply.
Does a 457(b) have a Roth option?
A governmental 457(b) can offer a designated Roth feature if the plan adopts it.
Does a 457(b) have a special catch-up?
Yes. Plans can offer a special catch-up during the final three taxable years before the plan's normal retirement age, subject to detailed unused-deferral rules.
Bottom line
If you have access to both a 401(k) and governmental 457(b), you have an unusually powerful savings setup.
The plans can give you two separate contribution limits, and the 457(b) can provide better early-distribution treatment after leaving employment. But the 401(k) may still deserve the first contribution if it offers the better employer match.
