457b vs 401k: Key Differences and 2026 Limits

A 457(b) and a 401(k) are employer-sponsored retirement plans that may allow employees to contribute part of their pay on a pretax or Roth basis. Both can provide tax advantages, employer contributions, investment growth, and access to retirement savings after leaving a job.

The primary difference between a 457b vs 401k is employer eligibility and the rules for accessing the money. State and local governments commonly offer governmental 457(b) plans, while private-sector employers generally offer 401(k) plans. Distributions from a governmental 457(b) after separation from employment are generally not subject to the federal 10% early-distribution tax, even when the participant is younger than 59½. A 401(k) distribution before age 59½ may incur that additional tax unless an exception applies.

Another major advantage arises when an employee has access to both plans: a governmental 457(b) generally has a separate employee-deferral limit from a 401(k). An eligible employee may therefore be able to contribute up to $24,500 to each plan in 2026—a combined $49,000 before applicable catch-up contributions.

However, plan features vary. Investment options, employer contributions, vesting, fees, withdrawal provisions, Roth availability, and legal protections should all be reviewed before deciding where to contribute.

457b vs 401k at a Glance

Feature	457(b) plan	401(k) plan
Typical employer	State or local government; certain tax-exempt organizations	Private-sector employer
2026 basic employee deferral limit	$24,500	$24,500
2026 standard age-50 catch-up	$8,000 for eligible governmental plans	$8,000
2026 catch-up for ages 60–63	$11,250 when applicable	$11,250
Special catch-up	Potential final three-year catch-up	No comparable three-year rule
Traditional contributions	Usually available	Usually available
Roth contributions	Available if the plan offers them	Available if the plan offers them
Employer contributions	May be available	May be available
Employer contributions count toward employee limit?	Generally yes	Generally no; separate total limit applies
10% early-distribution tax after leaving employment	Generally no for governmental 457(b) money	May apply before age 59½ unless an exception applies
Loans	May be available	May be available
Rollovers	Broad options for governmental plans	Broad options for eligible distributions
ERISA coverage	Governmental plans generally exempt	Most private-employer plans covered
Creditor protection	Governmental plan assets generally held for participants	Strong federal protection for most ERISA plans
Required minimum distributions	Generally apply to traditional accounts	Generally apply to traditional accounts

This comparison focuses primarily on governmental 457(b) plans. Nongovernmental 457(b) plans offered by certain tax-exempt employers follow substantially different funding, rollover, eligibility, and creditor rules.

What Is a 457(b) Plan?

A 457(b) is a tax-advantaged deferred-compensation plan.

Eligible employers may include:

• State governments
• Local governments
• Cities and counties
• Public agencies
• Police and fire departments
• Municipal organizations
• Certain public universities
• Some public school systems
• Certain tax-exempt organizations

A participating employee can usually elect to defer part of each paycheck into the plan. Traditional contributions generally reduce current federally taxable income, while qualified Roth distributions may be tax-free if the plan offers a designated Roth account and applicable requirements are satisfied.

The plan’s value depends on:

• Employee contributions
• Employer contributions
• Investment performance
• Administrative and investment fees
• Withdrawals
• Loans
• Time invested

A 457(b) is a defined-contribution arrangement. It does not ordinarily promise a specific lifetime payment using a salary-and-service formula like a traditional pension.

Governmental vs Nongovernmental 457(b) Plans

It is essential to identify which type of 457(b) an employer offers.

Governmental 457(b)

A governmental 457(b) is sponsored by a state or local government or an eligible governmental entity.

Governmental plans generally:

• Hold plan assets in trust for participants
• May allow Roth contributions
• May offer age-based catch-up contributions
• May accept or permit eligible rollovers
• Can provide broader rollover choices after separation
• Are not usually subject to ERISA
• Provide the special early-withdrawal tax advantage associated with eligible 457(b) distributions

Nongovernmental 457(b)

Certain tax-exempt organizations may provide a nongovernmental 457(b), sometimes called a tax-exempt 457(b) or top-hat plan.

These plans can differ significantly:

• Eligibility may be limited to highly compensated or select management employees.
• Assets generally remain the employer’s property.
• The assets may be available to the employer’s general creditors.
• Roth contributions generally are not available in the same manner as governmental 457(b) plans.
• Rollover options are much more limited.
• Distribution elections can be less flexible.
• Employer financial stability becomes an important risk consideration.

Employees should not assume that every 457(b) provides the same protections and portability.

What Is a 401(k) Plan?

A 401(k) is a workplace defined-contribution retirement plan commonly offered by private-sector employers.

Employers that may offer a 401(k) include:

• Corporations
• Small businesses
• Retail companies
• Technology firms
• Manufacturing companies
• Professional-service firms
• Partnerships
• Eligible nonprofit employers
• Self-employed business owners through an individual 401(k)

Employees generally contribute through payroll deductions. Depending on the plan, contributions may be:

• Traditional pretax
• Designated Roth
• After-tax employee contributions
• A combination of permitted contribution types

An employer may also provide:

• Matching contributions
• Nonelective contributions
• Profit-sharing contributions
• Qualified nonelective contributions
• Other plan-permitted funding

The employee normally chooses investments from a menu selected by the plan’s fiduciaries.

The Biggest Difference: Employer Eligibility

The most visible difference between a 457(b) and a 401(k) is the type of employer offering the plan.

Governmental 457(b) plans are commonly associated with public employees such as:

• Police officers
• Firefighters
• State employees
• City and county employees
• Public administrators
• Municipal workers
• Certain public-university employees
• Other state or local government workers

A 401(k) is generally associated with private-sector employment.

An employee does not usually select which plan type the employer maintains. The practical decision is whether to participate in the available plan and how much to contribute.

Some governmental employees have access to a 457(b) alongside a pension, 401(k), 401(a), or 403(b). Having more than one plan can create additional saving capacity, but every plan’s limits and coordination rules must be reviewed.

457b vs 401k Contribution Limits for 2026

The basic employee-deferral limit is the same for both plans.

For 2026:

• Basic employee elective-deferral limit: $24,500
• Standard age-50 catch-up: $8,000
• Higher catch-up for participants ages 60–63: $11,250
• General 401(k) annual-additions limit: $72,000, excluding eligible catch-up contributions

The IRS 2026 retirement-plan limits confirm that the $24,500 employee limit applies to 401(k), 403(b), and governmental 457 plans.

The limits can change in future years through cost-of-living adjustments.

Can You Max Out Both a 457(b) and a 401(k)?

Potentially, yes.

A governmental 457(b) generally has a separate elective-deferral limit from a 401(k). If an employer provides both plans and the employee is eligible, the employee may contribute up to the maximum in each.

For 2026:

• 457(b) employee contribution: $24,500
• 401(k) employee contribution: $24,500
• Combined employee deferrals: $49,000

The calculation is:

$24,500 + $24,500 = $49,000

This separate-limit treatment is one of the most valuable differences between a governmental 457(b) and other workplace plans.

By contrast, employee elective deferrals to a 401(k) and 403(b) generally share one individual annual limit. Our 403b vs 401k comparison explains how those plans coordinate their employee contributions.

The ability to contribute $49,000 does not mean everyone should do so. An employee must have sufficient eligible compensation and enough cash flow for housing, insurance, debt payments, emergencies, and other goals.

Employer Contributions Work Differently

Both 457(b) and 401(k) plans may allow employer contributions, but the limits operate differently.

Governmental 457(b)

Employee and employer contributions generally share the same annual 457(b) limit.

Suppose an employer contributes $4,500 to an employee’s governmental 457(b) during 2026. The amount remaining under the standard $24,500 limit would generally be:

$24,500 − $4,500 = $20,000

The employee could therefore contribute up to $20,000 before catch-up rules, assuming no other limitation applies.

401(k)

The employee’s $24,500 elective-deferral limit is separate from the broader annual-additions limit that includes employer contributions.

For 2026, the general 401(k) annual-additions limit is the lesser of:

• $72,000
• 100% of eligible compensation

Applicable catch-up contributions can generally be added beyond that amount.

Suppose an employee contributes $24,500 and the employer contributes $10,000:

$24,500 + $10,000 = $34,500

This remains below the $72,000 general annual-additions limit.

Plan terms, compensation limits, nondiscrimination rules, and contribution types can affect the calculation.

Age-50 Catch-Up Contributions

An eligible employee who is age 50 or older by the end of 2026 may be permitted to contribute an additional $8,000.

This produces a potential employee-deferral total of:

$24,500 + $8,000 = $32,500

The standard age-50 catch-up may be available under:

• 401(k) plans
• 403(b) plans
• Governmental 457(b) plans
• Certain other qualifying plans

A nongovernmental 457(b) does not use the age-50 catch-up in the same way.

Higher Catch-Up for Ages 60–63

Under the SECURE 2.0 Act, an increased catch-up limit applies to many participants who turn age 60, 61, 62, or 63 during the calendar year.

For 2026, the higher catch-up is $11,250 instead of the standard $8,000.

An eligible participant could therefore contribute:

$24,500 + $11,250 = $35,750

This higher limit applies only during the years in which the participant falls within the specified age range and only when the plan provides the applicable catch-up feature.

The Special 457(b) Three-Year Catch-Up

A 457(b) may offer a special catch-up during the three years immediately before the participant reaches the plan’s normal retirement age.

The potential limit is generally the lesser of:

1. Twice the regular annual limit; or
2. The regular limit plus unused eligible deferrals from prior years

For 2026, twice the regular limit would be:

$24,500 × 2 = $49,000

However, an employee does not automatically qualify to contribute $49,000.

The actual special catch-up depends on unused deferral capacity from prior eligible years. Someone who contributed the maximum every year may have no unused amount available.

A governmental 457(b) participant generally cannot use both the age-based catch-up and the special three-year catch-up in the same year. When eligible for both, the participant typically uses whichever produces the higher permitted limit.

The IRS guidance on 457 plan catch-ups explains the unused-deferral requirement and final-three-year period.

The Biggest Withdrawal Difference

Governmental 457(b) plans provide an important potential advantage for employees who leave work before age 59½.

After separation from employment, distributions of eligible governmental 457(b) money generally are not subject to the federal 10% additional tax on early distributions. Ordinary federal and state income taxes may still apply to traditional withdrawals.

A 401(k) distribution before age 59½ may be subject to:

• Ordinary income tax
• A 10% federal additional tax
• Possible state taxes or penalties

Exceptions may apply to a 401(k), including certain distributions after separating from service during or after the year the participant reaches age 55. Other statutory exceptions may also apply.

Example

Assume a 52-year-old employee leaves a municipal job and withdraws $20,000 from a traditional governmental 457(b).

Potential federal treatment:

• $20,000 generally included in taxable income
• No 10% early-distribution tax on eligible original 457(b) money

If the same employee withdrew $20,000 from a 401(k) without qualifying for an exception, the possible additional tax would be:

$20,000 × 10% = $2,000

The participant could therefore owe ordinary income tax plus a potential $2,000 additional federal tax.

This example is simplified and does not address withholding, state taxes, rolled-in money, exceptions, or individual circumstances.

Important Rule for Money Rolled Into a 457(b)

The early-withdrawal advantage may not apply identically to money that was rolled into a governmental 457(b) from a 401(k), 403(b), or IRA.

Amounts attributable to certain rollovers can retain separate tax treatment and may be subject to the 10% additional tax when withdrawn early unless an exception applies.

The plan administrator should track rollover sources separately. Before moving outside retirement money into a 457(b), ask how the rollover will affect future withdrawal taxes.

When Can You Withdraw From a 457(b)?

A 457(b) may permit distributions following events such as:

• Separation from employment
• Reaching a specified age
• An unforeseeable emergency
• Plan termination
• A qualifying small-balance distribution
• Death
• Another event permitted by federal rules and the plan document

Availability does not mean a withdrawal is financially advisable. Taking money early reduces the amount available for future tax-advantaged growth.

When Can You Withdraw From a 401(k)?

A 401(k) may allow distributions after:

• Separation from employment
• Reaching age 59½
• Disability
• Death
• Plan termination
• A qualifying hardship
• Another plan-permitted event

The plan may also offer loans or in-service withdrawals. Taxes and the 10% additional tax depend on age, contribution source, distribution reason, and statutory exceptions.

If you leave an employer, you may be able to keep the account, roll it over, transfer it to another eligible plan, or withdraw it. Our guide explains what happens to a 401k when you quit.

Unforeseeable Emergency vs 401(k) Hardship

Both plans may allow limited access for serious financial needs, but their legal standards differ.

457(b) Unforeseeable Emergency

A 457(b) unforeseeable-emergency distribution may be available for an extraordinary and unforeseeable financial hardship arising from events beyond the participant’s control.

Possible examples can include:

• Severe illness or accident
• Property loss from a casualty
• Certain funeral expenses
• Imminent foreclosure or eviction
• Other qualifying extraordinary circumstances

The amount generally cannot exceed the amount reasonably necessary to address the emergency after considering available resources.

401(k) Hardship Distribution

A 401(k) hardship distribution generally requires an immediate and heavy financial need and must be limited to the necessary amount.

Potential qualifying expenses can include:

• Certain medical expenses
• Purchase of a principal residence
• Tuition and educational costs
• Preventing eviction or foreclosure
• Funeral expenses
• Certain home-repair costs
• Certain disaster-related expenses

Plan documents determine which hardship provisions are offered.

Loans

A governmental 457(b) or 401(k) may permit participant loans, but neither plan is required to offer them.

A plan loan may avoid immediate taxation if it satisfies federal requirements and the repayment schedule is followed.

Before borrowing, review:

• Maximum loan amount
• Interest rate
• Origination fee
• Payroll-repayment requirements
• Repayment period
• Consequences of leaving employment
• Loan-offset rollover rules
• Investment growth lost while money is borrowed

A loan can become taxable if payments stop or the arrangement violates plan requirements.

Traditional vs Roth Contributions

Both governmental 457(b) and 401(k) plans may offer traditional and designated Roth contributions.

Traditional Contributions

Traditional contributions are generally made before federal income tax.

Potential advantages include:

• Lower current taxable income
• Tax-deferred investment growth
• Possible lower taxes during retirement

Withdrawals are generally taxable as ordinary income.

Roth Contributions

Roth contributions are made with after-tax money.

Qualified Roth distributions can generally be tax-free when:

• The applicable five-year requirement is satisfied
• The participant reaches age 59½, dies, or becomes disabled under the relevant rules

Not every plan offers a Roth option.

Roth Catch-Up Requirements for Higher Earners

Beginning in 2026, certain higher-paid participants may be required to make age-based catch-up contributions on a Roth basis.

For determining the requirement in 2026, the relevant prior-year wage threshold is generally $150,000 from the employer sponsoring the plan.

The rule involves additional details concerning:

• Which wages count
• Which employer paid them
• Whether the plan offers Roth contributions
• Which catch-up provision is used
• Plan implementation and administrative rules

Ask the employer or plan administrator how the 2026 Roth catch-up requirement affects payroll elections.

Investment Options

Neither the 457(b) nor the 401(k) label determines investment quality.

Possible investments include:

• Target-date funds
• U.S. stock funds
• International stock funds
• Bond funds
• Index funds
• Actively managed mutual funds
• Stable-value funds
• Money-market funds
• Collective investment trusts
• Annuity or fixed-account options
• Brokerage windows in some plans

Review each option’s:

• Expense ratio
• Investment objective
• Asset allocation
• Risk
• Historical consistency
• Turnover
• Restrictions
• Additional administrative expenses

A short menu of diversified, inexpensive funds can be better than a large menu containing expensive or overlapping choices.

Fees

Possible plan costs include:

• Recordkeeping fees
• Administrative charges
• Investment expense ratios
• Advisory fees
• Managed-account fees
• Loan fees
• Distribution fees
• Individual transaction expenses
• Annuity charges
• Brokerage-window fees

Even a modest annual fee difference can affect long-term growth.

Suppose two accounts each earn 7% before fees, but:

• Plan A costs 0.20% annually
• Plan B costs 1.20% annually

The approximate net returns would be:

• Plan A: 6.80%
• Plan B: 5.80%

The one-percentage-point difference can compound into a substantial amount over several decades.

Employer Matching Contributions

Both plan types may provide employer contributions, but a match is not guaranteed.

Possible contribution formulas include:

• Dollar-for-dollar matching
• Partial matching
• Fixed employer contributions
• Contributions based on years of service
• Discretionary funding
• No employer contribution

Review the vesting schedule as well as the amount.

Employee contributions are generally fully vested. Employer contributions may require a period of service before they become completely nonforfeitable, depending on the plan and contribution arrangement.

Legal and Creditor Protection

401(k)

Most private-employer 401(k) plans are governed by ERISA. These plans generally provide strong federal protections against many creditors, although exceptions and qualified domestic-relations orders can apply.

Governmental 457(b)

Governmental plans are generally exempt from ERISA. Plan assets are normally held in trust for participants, but applicable federal and state protections should be reviewed.

Nongovernmental 457(b)

Assets generally remain the property of the sponsoring tax-exempt employer and may be exposed to the employer’s general creditors.

This employer-credit risk is one of the most important considerations for a nongovernmental 457(b).

Rollovers

Eligible governmental 457(b) distributions can generally be rolled into accounts such as:

• Traditional IRA
• Another governmental 457(b)
• 401(k) plan that accepts rollovers
• 403(b) plan that accepts rollovers
• Roth IRA through a taxable conversion
• Another eligible retirement arrangement

A 401(k) may also be rolled to an IRA or another accepting employer plan when the distribution is eligible.

Nongovernmental 457(b) rollover options are much more restricted and should be reviewed carefully before making a distribution election.

A direct trustee-to-trustee transfer can generally avoid mandatory withholding that may apply to a distribution paid directly to the participant.

Required Minimum Distributions

Traditional 457(b) and 401(k) accounts are generally subject to required minimum distribution rules.

The starting age depends on the participant’s birth year under current law. Certain participants may be able to delay distributions from a current employer’s plan when the plan and federal rules permit it.

Under current federal rules, original owners generally do not have lifetime RMDs from designated Roth 401(k) or governmental Roth 457(b) accounts. Beneficiary distribution rules still apply after the owner’s death.

Tax laws can change, so participants should check current requirements before reaching the applicable age.

457(b) Advantages

Potential advantages of a governmental 457(b) include:

• Separate deferral limit from a 401(k) or 403(b)
• No general 10% early-distribution tax after separation
• Pretax and potentially Roth contributions
• Possible employer funding
• Special final-three-year catch-up
• Payroll-deduction convenience
• Potential access after leaving public employment
• Rollovers for eligible governmental-plan distributions
• Ability to supplement a pension

457(b) Disadvantages

Potential disadvantages include:

• Employer contributions generally reduce the employee’s available annual limit.
• Investment choices may be limited.
• Fees may be high.
• The special catch-up calculation can be complicated.
• Governmental plans usually are not covered by ERISA.
• Rolled-in money may have different early-distribution treatment.
• Nongovernmental plans create employer-credit and portability risks.
• Early access can reduce long-term retirement security.
• A plan does not guarantee investment gains.

401(k) Advantages

Potential advantages include:

• Pretax and possibly Roth contributions
• Employer matching or profit sharing
• Separate employee and total contribution limits
• Strong federal protections for most ERISA plans
• Potentially low-cost institutional investments
• Loans when offered
• Broad rollover options
• Familiar administration and payroll deductions
• Portability after changing jobs

401(k) Disadvantages

Potential disadvantages include:

• The employer selects the investment menu.
• Some plans charge high fees.
• Employer contributions may vest over time.
• Withdrawals before age 59½ may create an additional tax.
• Loans can reduce retirement growth.
• A limited fund menu may make diversification harder.
• Investment losses can reduce the balance.
• The plan does not promise a fixed retirement income.

This differs from comparing a pension and 401k, because a traditional pension generally promises a formula-based benefit rather than an individual investment-account balance.

Which Should You Fund First?

If you have access to both plans, consider the following order as a starting framework—not a universal recommendation.

1. Capture the Full Employer Match

If one plan offers a match, consider contributing enough to obtain the maximum available employer contribution.

Failing to receive the full match can mean leaving part of the compensation package unused.

2. Build an Emergency Reserve

Retirement contributions should not leave you unable to pay for ordinary emergencies. Maintain enough accessible savings for deductibles, repairs, medical costs, job changes, and other unexpected expenses.

3. Compare Fees and Investment Options

After obtaining the match, direct additional savings toward the plan with:

• Lower costs
• Better diversified investments
• Stronger stable-value or fixed-income options
• More useful Roth features
• Better withdrawal provisions
• More flexible beneficiary rules

4. Consider Expected Retirement Age

A governmental 457(b) may be particularly useful for someone who expects to leave employment before age 59½ because eligible original 457(b) money may be accessible without the general 10% additional tax.

5. Use the Second Plan for Additional Saving

After reaching the preferred plan’s limit, use the other account when affordable and appropriate.

Example: Contributing to Both Plans

Assume a 45-year-old public employee earns $110,000 and has access to both a governmental 457(b) and a 401(k).

The employee contributes:

• $24,500 to the 457(b)
• $24,500 to the 401(k)

Combined employee deferrals:

$24,500 + $24,500 = $49,000

Suppose the employer also contributes $5,000 to the 401(k).

Total retirement funding:

$49,000 + $5,000 = $54,000

The 457(b) employer and employee contributions must remain within the applicable 457(b) limit. The 401(k) employer contribution is evaluated under the broader 401(k) annual-additions limit.

This example does not account for payroll taxes, plan-specific compensation rules, nondiscrimination testing, other employer plans, or individual tax circumstances.

Common Mistakes

Assuming Every 457(b) Is Governmental

A nongovernmental plan has different creditor, rollover, funding, and distribution rules. Identify the sponsoring employer and plan type.

Believing 457(b) and 401(k) Contributions Share One Limit

A governmental 457(b) generally has a separate employee-deferral limit, potentially allowing much larger combined contributions.

Ignoring Employer Contributions to the 457(b)

Employer contributions generally count toward the same 457(b) limit as employee deferrals.

Assuming All 457(b) Withdrawals Avoid the 10% Tax

The favorable rule may not apply the same way to money rolled into the plan from another account.

Missing the Employer Match

Check both plans before deciding where to direct contributions.

Using Both Catch-Ups in the Same Year

A governmental 457(b) participant generally cannot combine the age-based catch-up and special final-three-year catch-up for the same year.

Ignoring Vesting

Employer contributions may not belong fully to the employee until service requirements are satisfied.

Choosing Investments Only by Past Performance

Recent returns do not guarantee future performance. Consider fees, diversification, risk, and time horizon.

Cashing Out After Leaving a Job

Immediate access does not make a withdrawal necessary. Cashing out can generate taxes and reduce future retirement income.

Frequently Asked Questions

Is a 457(b) better than a 401(k)?

Not automatically. A governmental 457(b) can provide penalty-free access after separation and a separate contribution limit. A 401(k) may offer a better match, stronger ERISA protection, more investments, or lower fees. Compare the actual plans.

Is a 457(b) the same as a 401(k)?

No. They are established under different sections of the tax code, are commonly offered by different employers, and follow different contribution and distribution rules.

Can I contribute to a 457(b) and 401(k) at the same time?

Yes, if eligible. A governmental 457(b) generally has a separate employee-deferral limit from a 401(k). In 2026, an employee could potentially contribute $24,500 to each before applicable catch-ups.

What is the 457(b) contribution limit for 2026?

The basic limit is generally $24,500. Eligible catch-up contributions may increase it.

What is the 401(k) contribution limit for 2026?

The basic employee elective-deferral limit is $24,500. The general annual-additions limit is $72,000, excluding applicable catch-ups.

Can I withdraw from a 457(b) before age 59½?

Eligible distributions from a governmental 457(b) after separation are generally not subject to the federal 10% additional tax, although ordinary income taxes may apply. Rolled-in amounts can be treated differently.

Can I withdraw from a 401(k) before age 59½?

Potentially, but taxes and a 10% additional federal tax may apply unless an exception is available. The plan must also permit the distribution.

Does a 457(b) have an employer match?

It can, but employer contributions generally count toward the same annual 457(b) limit as employee contributions.

Does a 401(k) have an employer match?

It may, depending on the employer. Matching formulas and vesting vary.

Can I roll a 457(b) into an IRA?

An eligible distribution from a governmental 457(b) can generally be rolled into an IRA. Nongovernmental 457(b) plans have more restrictive rollover rules.

Can I roll a 401(k) into a 457(b)?

A governmental 457(b) may accept an eligible rollover if the plan permits it. Ask how rolled-in funds will be tracked and taxed upon early withdrawal.

Does a 457(b) have a Roth option?

A governmental plan may offer designated Roth contributions. Availability depends on the plan. Nongovernmental 457(b) arrangements generally differ.

Can a 457(b) lose money?

Yes. The account can decline when its investments lose value. Fees and withdrawals can also reduce the balance.

Is a 457(b) a pension?

No. A 457(b) is generally a defined-contribution deferred-compensation plan. Some public employees receive both a pension and access to a 457(b).

Final Thoughts

The most important differences in the 457b vs 401k comparison involve employer eligibility, contribution coordination, catch-up rules, and early withdrawals.

For 2026, both plans have a $24,500 basic employee-deferral limit. An eligible employee with access to a governmental 457(b) and a 401(k) may be able to contribute $24,500 to each, producing $49,000 in combined employee deferrals before catch-ups.

A governmental 457(b) also offers a notable early-retirement advantage: eligible distributions after separation are generally not subject to the federal 10% additional tax. Meanwhile, a 401(k) may provide a more generous employer contribution, a larger total contribution limit, stronger ERISA protections, or better investments.

Neither plan is automatically superior. Compare:

• Employer contributions
• Vesting
• Investment choices
• Fees
• Roth options
• Withdrawal rules
• Catch-up eligibility
• Creditor protection
• Rollover options
• Expected retirement age
• The employer’s financial condition for a nongovernmental plan
