403b vs. 457b: Key Differences and 2026 Limits

The main difference between a 403b vs 457b is who can sponsor the plan and how participants can access the money after leaving employment.

A 403(b) is generally offered by public schools, certain tax-exempt organizations and eligible churches or ministers. A 457(b) is a deferred-compensation plan offered by state and local governments and certain tax-exempt organizations. Governmental 457(b) plans generally allow distributions after separation from service without the usual 10% federal additional tax on early distributions, regardless of the participant’s age. A 403(b) distribution before age 59½ may face that additional tax unless an exception applies.

Both plans can provide traditional tax-deferred contributions and may offer designated Roth contributions. For 2026, the basic employee contribution limit is $24,500 for each. Importantly, the 457(b) limit is generally separate from the combined elective-deferral limit applying to 403(b) and 401(k) plans. Someone eligible for both a 403(b) and a governmental 457(b) may therefore be able to defer as much as $49,000 in basic employee contributions for 2026, before applicable catch-ups, subject to compensation and plan rules.

That does not make the 457(b) automatically better. Employer contributions, investments, fees, vesting, distribution options and whether the 457(b) is governmental or nongovernmental can change the decision.

Required minimum distributions	Traditional balances generally subject to RMD rules	Traditional balances generally subject to RMD rules

This table describes general federal rules. The employer’s written plan can be more restrictive, and nongovernmental 457(b) plans differ significantly from governmental plans.

What Is a 403(b) Plan?

A 403(b) is an employer-sponsored retirement plan available to employees of eligible organizations, including:

Public elementary and secondary schools
Public colleges and universities
Certain 501(c)(3) nonprofit organizations
Churches and church-related organizations
Certain eligible ministers

Employees commonly contribute through payroll deductions. Traditional contributions generally reduce current taxable income, and investment earnings grow tax-deferred until distributed. If the plan offers a designated Roth account, Roth contributions are made after tax; qualified Roth distributions can be tax-free when the applicable requirements are satisfied.

A 403(b) may hold mutual funds through custodial accounts, annuity contracts or other permitted investments. Available investments and costs depend on the employer and vendors.

The plan may also provide:

Employer matching contributions
Nonelective employer contributions
Loans
Hardship distributions
Roth contributions
In-plan Roth conversions
Automatic enrollment

None of these features is guaranteed. Review the summary plan description and fee disclosures.

What Is a 457(b) Plan?

A 457(b) is an eligible deferred-compensation plan. There are two materially different types.

Governmental 457(b)

State and local government employers may sponsor governmental 457(b) plans. Participants can include state employees, city workers, firefighters, police officers and employees of public institutions.

Governmental plans can offer traditional and designated Roth contributions. Assets must generally be held in trust, custodial accounts or qualifying annuity contracts for participants and beneficiaries.

Nongovernmental 457(b)

Certain tax-exempt organizations may establish nongovernmental 457(b) plans, often for a limited group of management or highly compensated employees.

These plans carry important differences:

Assets generally remain the employer’s property and are subject to claims by its general creditors.
Eligible rollovers to an IRA, 403(b), 401(k) or governmental 457(b) generally are not available.
Distribution timing can be less flexible and may be controlled by elections and plan terms.
Roth treatment is generally not available in the same way as under a governmental 457(b).

Do not evaluate a nongovernmental 457(b) as though it were a governmental plan. Employer financial strength and the required distribution schedule deserve close attention.

Who May Have Access to Both Plans?

Some public-sector and nonprofit employees may be offered both a 403(b) and 457(b). Examples can include:

Public-school employees
University employees
Employees of public hospitals
Workers at certain nonprofit health systems
Employees of other eligible governmental or tax-exempt organizations

Eligibility is determined by the employer and plan documents. Having access to both does not mean every employee receives identical matching contributions, investment menus or withdrawal features.

403b vs. 457b Contribution Limits for 2026

The IRS announced the following limits for 2026.

Basic employee contribution limit

The basic elective-deferral limit for 403(b) plans and the annual deferral limit for governmental 457(b) plans is:

$24,500 for 2026

The same headline number applies, but the limits operate differently.

For a 403(b), employee elective deferrals generally share a single personal limit with elective deferrals to a 401(k), SIMPLE plans aside from their separate rules, and certain other arrangements. Participating in multiple employers’ 403(b) or 401(k) plans does not create a separate $24,500 limit for each.

The 457(b) annual limit is generally separate. However, both employee and employer contributions to a 457(b) generally count toward the applicable 457(b) limit.

Can you contribute $24,500 to both?

Potentially, yes. If your employer offers both a 403(b) and an eligible 457(b), you may generally contribute up to the separate basic limit for each:

403(b): $24,500
457(b): $24,500
Potential basic combined deferral: $49,000

Your compensation, plan limits, payroll deadlines and other contributions can reduce what is permitted.

Age-50 catch-up for 2026

For participants who are at least age 50 by the end of 2026, the general catch-up limit is $8,000, if the plan permits it.

For governmental 457(b) plans, the age-based catch-up may also be available. Nongovernmental 457(b) plans do not offer the standard age-50 catch-up.

Higher catch-up for ages 60–63

Under SECURE 2.0, a higher catch-up applies to eligible participants who are ages 60, 61, 62 or 63 at the end of the year. For 2026, the higher amount is $11,250 instead of the standard $8,000 catch-up, when the plan permits the contribution.

Plan administration and Roth catch-up requirements can affect implementation. Confirm eligibility and payroll treatment with the plan administrator before setting a contribution rate.

Special 403(b) 15-Year Catch-Up

Some 403(b) plans maintained by qualifying organizations allow a special catch-up for employees with at least 15 years of service with that employer.

The potential additional contribution is generally limited to the smallest of:

$3,000
$15,000 minus prior special 15-year catch-up contributions
$5,000 multiplied by years of service, minus prior elective deferrals made for the employee

The calculation is technical, and not every employer or participant qualifies. When both the 15-year catch-up and age-based catch-up are available, contributions must be allocated in the proper order. Do not assume that 15 years of employment automatically adds $3,000; ask the plan administrator to calculate the permitted amount.

Special 457(b) Three-Year Catch-Up

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

The limit can be the lesser of:

Twice the basic annual 457(b) limit, or
The basic annual limit plus unused eligible deferral room from prior years under the plan

With a $24,500 basic limit for 2026, twice that amount is $49,000. However, a participant needs sufficient unused prior-year room and must meet the timing and plan requirements to reach the maximum.

For a governmental 457(b), someone eligible for both the age-based catch-up and the special three-year catch-up generally uses whichever permits the larger contribution—not both in the same year.

Employer Match and Total Contribution Rules

An employer match can determine which plan should receive the first dollar.

403(b) employer contributions

Employer matching and nonelective contributions do not use the employee’s $24,500 elective-deferral limit, but they count toward the broader annual-additions limit. For 2026, that general limit is $72,000 or 100% of includible compensation, whichever is less, before applicable age-based catch-up contributions. Special rules can affect the calculation.

457(b) employer contributions

Employer contributions to a 457(b) generally count toward the same annual limit that applies to participant deferrals. For example, if the total 457(b) limit is $24,500 and the employer contributes $2,500, the employee may have only $22,000 of remaining basic deferral room, absent a catch-up.

This difference can make an employer-funded 403(b) particularly valuable while preserving separate 457(b) capacity.

Withdrawal Rules: The Biggest Practical Difference

Contribution limits attract attention, but withdrawal rules often determine which plan is more flexible.

403(b) withdrawals

A 403(b) generally permits distributions after events specified by federal law and the plan, such as:

Reaching age 59½
Separation from employment
Disability
Death
Financial hardship, if the plan permits

Traditional distributions are generally taxed as ordinary income. A taxable distribution before age 59½ may also face a 10% federal additional tax unless an exception applies.

One important exception may apply after separation from service during or after the year the participant reaches age 55. Other exceptions can apply depending on the facts.

Governmental 457(b) withdrawals

After separation from the employer, distributions from a governmental 457(b) generally are not subject to the 10% additional tax on early distributions, even if the participant is younger than 59½. Traditional distributions remain subject to ordinary income tax.

This feature can make a governmental 457(b) valuable for someone planning to retire or leave public service before age 55.

An important exception applies to money rolled into the 457(b) from a 401(k), 403(b) or IRA. The portion attributable to those rollover contributions may remain subject to the 10% additional tax unless another exception applies. Keep rollover-source records and review the plan’s accounting.

Nongovernmental 457(b) distributions

Nongovernmental plans may impose a predetermined payment date or schedule. A participant leaving employment can face taxable distributions before the money is needed, depending on plan terms and prior elections. Because rollover options are generally unavailable, distribution planning is especially important.

Unforeseeable Emergency vs. Hardship Distribution

Both plans may offer limited access during severe financial difficulty, but the standards differ.

A 403(b) plan may allow a hardship distribution for an immediate and heavy financial need under applicable rules and plan terms.

A 457(b) may allow a distribution for an unforeseeable emergency, generally involving a severe financial hardship caused by circumstances beyond the participant’s control. The standard can be narrower than the 403(b) hardship rules.

A permitted distribution is not necessarily tax-free. It also permanently removes money from retirement savings and can reduce future compounding.

Loans

Either plan may permit participant loans, but plans are not required to offer them.

Before borrowing, review:

Maximum loan amount
Interest rate and fees
Repayment period
Payroll repayment requirements
Treatment after leaving employment
Consequences of default or loan offset

A loan can interrupt investment growth, and an unpaid balance may create a taxable event. Do not select a retirement plan primarily because borrowing is available.

Investment Options and Fees

Investor.gov notes that 403(b) and 457(b) plans commonly offer mutual funds and annuities. The actual menu varies widely.

Compare:

Broad-market index funds
Target-date funds
Actively managed funds
Fixed or variable annuities
Stable-value or capital-preservation options
Administrative fees
Fund expense ratios
Advisory or managed-account fees
Annuity contract expenses
Surrender charges and transfer restrictions

A strong tax structure cannot compensate for unnecessarily high fees over a long career. Compare each fund’s expense ratio, benchmark, risk and role in the portfolio.

If both plans have good low-cost investments, contribution limits and withdrawal flexibility become more important. If one plan has expensive products while the other offers diversified low-cost funds, the investment menu may change the order of contributions.

Vesting

Your salary deferrals are generally immediately vested. Employer contributions may follow a vesting schedule.

Before changing jobs, determine:

Your vested percentage
The date the next vesting milestone occurs
Whether prior service counts
What happens to unvested contributions
Whether returning to the employer can restore service credit

Do not confuse account balance with the amount you are entitled to keep.

Roth vs. Traditional Contributions

Both a 403(b) and a governmental 457(b) may offer designated Roth accounts.

Traditional contributions

Generally reduce current taxable income
Grow tax-deferred
Produce taxable distributions, except for any after-tax basis

Roth contributions

Do not reduce current taxable income
Grow tax-deferred
Can provide tax-free qualified distributions when applicable age, holding-period and distribution requirements are met

Roth availability is a plan feature, not a guarantee. Employer contributions and matching amounts may receive different tax treatment depending on plan design and current rules.

The choice depends on current and expected future tax rates, time horizon, cash flow and the value of tax diversification. See WealthLedger’s explanation of traditional vs. Roth workplace contributions for the underlying tax comparison.

Rollovers After Leaving the Employer

403(b) rollover options

An eligible 403(b) distribution can generally be rolled into:

Another 403(b)
A qualifying 401(k) or other eligible employer plan that accepts it
A governmental 457(b) that accepts rollovers
A traditional IRA

Roth amounts require compatible Roth treatment. Direct rollovers can avoid mandatory withholding and reduce the risk of missing the 60-day deadline.

Governmental 457(b) rollover options

Eligible governmental 457(b) distributions can generally be rolled into another eligible employer plan or IRA. However, rolling governmental 457(b) money into an IRA or 403(b) can sacrifice the 457(b)’s distinctive early-access treatment. Someone expecting to need the money before age 59½ should analyze that consequence before moving it.

Nongovernmental 457(b) rollover limits

A nongovernmental 457(b) generally cannot be rolled into an IRA, 403(b), 401(k) or governmental 457(b). The plan’s distribution election therefore deserves careful planning before separation.

Required Minimum Distributions

Traditional 403(b) and 457(b) balances generally are subject to required minimum distribution rules. The starting age depends on birth year and current federal law. Workplace-plan exceptions may apply in certain circumstances when someone remains employed by the plan sponsor.

Designated Roth accounts in employer plans are generally no longer subject to lifetime RMDs for the original owner under current federal rules, although beneficiary requirements still apply.

Because RMD rules and plan procedures can change, confirm the applicable year and deadline with the plan administrator or a qualified tax adviser.

Governmental vs. Nongovernmental 457(b): Do Not Skip This Check

The label “457(b)” is incomplete without identifying the sponsor.

Issue	Governmental 457(b)	Nongovernmental 457(b)
Typical participant	State or local government employee	Select management or highly compensated nonprofit employee
Asset protection structure	Assets generally held in trust for participants	Assets remain subject to employer’s general creditors
Eligible rollovers	Generally available	Generally unavailable to IRAs and qualified plans
Roth option	May be offered	Generally unavailable
Age-based catch-up	May be offered	Not available
Distribution flexibility	Often broader	Can be restricted by plan terms and elections

Before contributing heavily to a nongovernmental plan, evaluate the employer’s financial condition, distribution schedule and concentration risk. The account is not equivalent to an IRA held in your name.

Which Plan Should You Fund First?

Use this order as a framework, not a universal rule.

1. Capture the strongest employer contribution

Contribute enough to receive any available match or employer contribution that would otherwise be forfeited, assuming the investment and employment terms are reasonable.

2. Compare investments and fees

Favor the plan with diversified, low-cost options when the employer benefits are similar.

3. Consider early-retirement access

A governmental 457(b) may deserve priority when you expect to leave service before age 55 and want potential access without the 10% additional tax.

4. Review asset and rollover risk

Treat a nongovernmental 457(b) cautiously because assets remain exposed to employer creditors and rollover options are limited.

5. Use both when appropriate

After obtaining employer benefits and maintaining emergency savings, using both plans can substantially increase tax-advantaged retirement capacity.

6. Coordinate the overall portfolio

Do not duplicate funds unintentionally or take more risk simply because accounts are separate. View both accounts as one retirement portfolio.

Example: Teacher With Both Plans

Assume a 45-year-old public-school employee has access to:

A 403(b) with a low-cost index fund and a modest employer contribution
A governmental 457(b) with comparable low-cost investments

For 2026, the employee could potentially defer $24,500 to the 403(b) and another $24,500 to the 457(b), for $49,000 in basic employee contributions, provided compensation and plan rules allow it.

A reasonable order might be:

Contribute enough to the 403(b) to capture the full employer contribution.
Use the governmental 457(b) for additional saving and potential early-retirement flexibility.
Return to the 403(b) if more tax-advantaged capacity is needed.

The best order changes if the 457(b) has much higher fees, if the 403(b) lacks a match or if near-term cash needs make aggressive saving unsuitable.

403b vs. 457b vs. 401k

The three plans share tax-advantaged retirement features but serve different employers.

A 401(k) is commonly offered by private-sector employers.
A 403(b) is offered by public schools, certain nonprofits and eligible religious organizations.
A 457(b) is offered by state and local governments and certain tax-exempt organizations.

Elective deferrals to a 401(k) and 403(b) generally share the same personal annual limit. A 457(b) has a separate limit. For a fuller employer and plan comparison, see 403(b) vs. 401(k) and 457(b) vs. 401(k).

Questions to Ask the Plan Administrator

Before enrolling or changing contributions, ask:

Is the 457(b) governmental or nongovernmental?
Does either plan provide an employer match or nonelective contribution?
What vesting schedule applies?
Which funds and annuities are available, and what are their total fees?
Does the plan offer traditional and Roth contributions?
Which catch-up contributions does the plan permit?
How does payroll coordinate contributions to both plans?
Are loans or emergency withdrawals available?
What distribution options apply after separation?
Can distributions be delayed or rolled over?
How are rollover-source assets tracked inside the 457(b)?
Which beneficiary designation is currently on file?

Keep copies of the summary plan description, fee disclosures, beneficiary confirmation and distribution elections.

Frequently Asked Questions

Is a 403(b) better than a 457(b)?

Not automatically. A 403(b) may provide a stronger employer match or better investments. A governmental 457(b) may offer more flexible access after leaving employment. Compare actual plan features rather than account names.

Can I contribute to both a 403(b) and 457(b)?

Yes, if your employer offers both and you are eligible. Their basic contribution limits are generally separate, potentially allowing $24,500 to each for 2026 before applicable catch-ups.

What is the 403(b) contribution limit for 2026?

The basic employee elective-deferral limit is $24,500. The general age-50 catch-up is $8,000, while eligible participants ages 60–63 may have an $11,250 catch-up. Plan terms and special rules apply.

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

The basic annual limit is $24,500. Employee and employer contributions generally count together. Governmental plans may allow age-based catch-ups, and eligible participants may qualify for the special three-year catch-up.

Can I max out a 403(b), 457(b) and IRA?

Potentially. Employer-plan contributions do not automatically prevent an IRA contribution, but income, filing status and workplace-plan coverage can affect whether a traditional IRA contribution is deductible and whether a direct Roth IRA contribution is permitted.

Does a 457(b) have an early-withdrawal penalty?

Governmental 457(b) distributions generally are not subject to the 10% additional tax after separation, even before age 59½. Amounts rolled into the plan from other account types may be treated differently. Nongovernmental distribution rules also require separate review.

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

An eligible governmental 457(b) distribution generally can be rolled into an IRA. A nongovernmental 457(b) generally cannot. Consider whether an IRA rollover would give up favorable early-access treatment.

Does a 403(b) have an early-withdrawal penalty?

A taxable 403(b) distribution before age 59½ may be subject to the 10% additional tax unless an exception applies. Separation during or after the year the participant turns 55 is one potential exception.

Can a 403(b) or 457(b) lose money?

Yes. Mutual funds, variable annuities and other investments can decline in value. Fixed products also carry inflation, liquidity, insurer and contract risks. Tax advantages do not guarantee returns.

Should I roll my governmental 457(b) into my 403(b)?

Only after comparing investments, fees, withdrawal rules and account-management needs. Moving 457(b) assets may give up its favorable treatment for distributions before age 59½.

Final Takeaway

The 403b vs. 457b decision is usually not an either-or choice.

A 403(b) can be valuable for employer contributions and retirement investing through a public-school or nonprofit employer. A governmental 457(b) adds a separate contribution limit and can provide unusually flexible access after separation from service. If both are available, using both may allow substantially more tax-advantaged saving.

First capture employer contributions, then compare fees and investments. Give extra weight to the governmental 457(b) if early retirement is a goal. Treat a nongovernmental 457(b) separately because its assets remain exposed to employer creditors and eligible rollovers are generally unavailable.

Finally, confirm current limits and plan-specific rules before changing payroll elections. Federal limits establish the maximum framework; the written plan determines which features you can actually use.

This article is for general educational purposes and does not constitute individualized investment, tax, legal or retirement advice. Contribution limits, catch-up eligibility, distribution rules, tax treatment and plan features can change and depend on the written plan and individual circumstances. Review current IRS guidance and plan documents and consult qualified professionals before contributing, withdrawing, rolling over or making distribution elections.
