Executive Summary

A 403(b) is an employer-sponsored retirement plan available to certain employees of public schools, tax-exempt organizations and certain ministers.

The IRS describes a 403(b)—also called a tax-sheltered annuity, or TSA, plan—as a retirement plan offered by public schools and certain Section 501(c)(3) tax-exempt organizations. Certain ministers can also participate under the rules.^[1][2]

Like a 401(k), a 403(b) generally allows eligible employees to defer part of their compensation into an individual retirement account within the employer plan.

Depending on the plan, contributions can include:

• Traditional pre-tax salary deferrals
• Designated Roth contributions
• Employer contributions
• Age-based catch-up contributions
• In some plans, a special 15-year-service catch-up

For 2026, the IRS basic elective-deferral limit is $24,500.^[3][5][6]

Eligible participants age 50 or older can generally make an additional $8,000 catch-up contribution if the plan permits it. Participants who attain ages 60, 61, 62 or 63 during 2026 can have a higher age-based catch-up limit of $11,250.^[3][5]

A feature unique to certain 403(b) plans is the special 15-year catch-up.

Eligible employees with at least 15 years of service with a qualifying organization may be allowed to defer up to an additional $3,000 for a year, subject to a statutory formula and a $15,000 lifetime limit.^[4]

That special catch-up is more complicated than the ordinary age-based catch-up and is not available in every 403(b) plan.

Key Takeaways

• A 403(b) is an employer-sponsored retirement plan for specified public-school, nonprofit and ministerial workers.^[1][2]
• It is an account structure, not an investment.
• Traditional salary deferrals generally receive tax-deferred treatment; designated Roth deferrals are made with after-tax dollars.^[1][7]
• The 2026 basic elective-deferral limit is $24,500.^[3][5]
• The general 2026 age-50 catch-up limit is $8,000.^[3][5]
• Eligible participants ages 60 through 63 have a higher 2026 age-based catch-up limit of $11,250.^[3][5]
• Certain qualifying long-service employees can use a separate special 15-year catch-up of up to $3,000 in a year, subject to a formula and $15,000 lifetime limit.^[4]
• The 2026 annual-additions limit is generally $72,000 before eligible catch-up contributions.^[5][6]
• 403(b) investment arrangements commonly involve annuity contracts and custodial accounts invested in mutual funds.^[1][8]
• A 403(b) can lose money because the investments inside the account can lose value.
• Designated Roth 403(b) accounts currently have no lifetime RMD requirement for the original owner.^[12]
• Plan loans and hardship distributions can be available if permitted by the plan.^[10][11]

What Does 403(b) Mean?

The name comes from Section 403(b) of the Internal Revenue Code.

Historically, these plans became associated with annuity contracts, which is why the IRS still uses the term tax-sheltered annuity plan.

Modern 403(b) arrangements can also use custodial accounts invested in mutual funds.^[1][8]

The legal section number describes the retirement-plan framework.

It does not describe one particular investment.

> ROIStreet Definition > > A 403(b) is an employer-sponsored defined contribution retirement arrangement available to specified public-school, tax-exempt and ministerial workers that allows retirement contributions to be invested under tax-advantaged rules.

Who Can Have a 403(b)?

A 403(b) is not available through every employer.

IRS guidance identifies eligible groups that can include:

• Employees of qualifying Section 501(c)(3) tax-exempt organizations
• Eligible employees of public school systems
• Employees of state colleges and universities that qualify under the public-education rules
• Certain church employees
• Certain ministers
• Certain other specifically eligible organizations and workers^[1][2]

Examples of workplaces commonly associated with 403(b) plans include:

• Public schools
• Public universities
• Hospitals organized as qualifying nonprofits
• Charitable organizations
• Churches and church-related organizations

A for-profit employer generally does not establish a 403(b) merely because it operates in education or health care.^[2]

A 403(b) Is Not Just for Teachers

Teachers are among the most visible 403(b) participants.

But the plan is broader than education.

A qualifying nonprofit hospital, charity or religious organization can also maintain a 403(b).

Conversely, not every employee working in an education- or health-related business is automatically eligible.

Employer legal status matters.

A 403(b) Is an Account, Not an Investment

A 403(b) can contain different investments depending on the plan and vendor.

Possible exposures can include:

• Mutual funds
• Fixed annuities
• Variable annuities
• Other permitted investment arrangements
• Cash or fixed-account features within available contracts

Two employees can both say:

“I have a 403(b).”

One may hold diversified stock and bond mutual funds.

Another may hold an annuity contract with materially different costs, guarantees, surrender terms and investment exposures.

The tax wrapper is similar.

The investment economics can be very different.

> Tax-Sheltered Does Not Mean Risk-Free > > The phrase describes tax treatment. It does not mean the investment is protected from market loss.

Traditional 403(b) Contributions

Traditional salary deferrals generally allow an employee to defer compensation into the plan before federal income tax is imposed on that deferred amount.

The contributions and investment earnings generally become taxable when distributed, subject to applicable rules.^[1][7]

This is commonly described as tax deferral.

Tax is postponed.

It is not necessarily eliminated.

Roth 403(b) Contributions

A 403(b) plan can also offer a designated Roth account.

Roth employee contributions are made with after-tax dollars.

Qualified Roth distributions can generally receive tax-free federal treatment when applicable requirements are satisfied.

A Roth 403(b) is still part of the employer-sponsored 403(b) plan.

It is not the same legal account as a Roth IRA.

Traditional vs. Roth 403(b)

Traditional and Roth describe tax treatment, not risk level.

The 2026 Basic Elective-Deferral Limit

For 2026, the IRS sets the basic elective-deferral limit for 403(b) plans at:

$24,500.^[3][5][6]

The participant cannot simply multiply this amount by the number of 403(b) contracts or vendors used.

The limit applies to eligible elective deferrals under applicable tax rules.

It can also interact with elective deferrals made to other employer plans.

Traditional and Roth Contributions Share the Limit

Suppose an employee under age 50 contributes during 2026:

• $14,500 traditional
• $10,000 Roth

Total elective deferrals:

$24,500

The basic limit has been reached.

The employee does not generally receive another $24,500 because both tax treatments are offered.

The 2026 Age-50 Catch-Up

If permitted by the plan, an employee who is age 50 or older by the end of the year can generally make an additional catch-up contribution.

For 2026, the standard age-based catch-up limit is:

$8,000.^[3][5]

For an eligible participant outside the special age-60-through-63 band, that can make total employee deferrals:

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

subject to plan terms and applicable rules.

Higher Catch-Up for Ages 60 Through 63

SECURE 2.0 created a higher age-based catch-up limit for employees who attain ages 60, 61, 62 or 63 during the year.

For 2026, the IRS amount is:

$11,250.^[3][5]

That can make total employee elective deferrals:

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

for an otherwise eligible participant.

This higher catch-up replaces the standard $8,000 age-based catch-up for the applicable year; it is not added on top of it.

2026 Roth Catch-Up Wage Threshold

For applicable employer plans, including 403(b) plans, SECURE 2.0 can require certain higher-wage participants to make catch-up contributions as designated Roth contributions.

For catch-up contributions made in 2026, the IRS states that the relevant prior-year wage threshold is:

$150,000.^[5]

The rule is technical and depends on wages from the sponsoring employer and other implementation details.

It does not mean all contributions above $150,000 of income must be Roth.

It relates specifically to applicable catch-up contributions.

The Special 15-Year 403(b) Catch-Up

The 403(b) system contains a catch-up rule not generally found in a 401(k).

Under IRS rules, certain employees with at least 15 years of service with a qualifying organization can be eligible for additional elective deferrals if the plan permits the special catch-up.^[4]

The annual increase is the least of:

1. $3,000
2. The unused portion of the $15,000 lifetime special-catch-up limit
3. A formula based on $5,000 multiplied by years of service minus prior elective deferrals to the organization’s plans^[4]

This means the special catch-up is not automatically $3,000.

The employee may qualify for less—or none—depending on contribution history.

Who Can Use the 15-Year Catch-Up?

IRS guidance limits the special catch-up to employees of specified qualifying organizations.

These can include certain:

• Educational organizations
• Hospitals
• Health and welfare service agencies
• Churches
• Church-related organizations^[4]

The employee must also satisfy the required service history.

Merely having a 403(b) for 15 calendar years does not automatically establish eligibility.

The $15,000 Lifetime Limit

The special 15-year catch-up has a lifetime ceiling.

IRS guidance states that the special catch-up formula imposes a $15,000 lifetime limit on additional elective deferrals made under that provision.^[4]

For example, if an employee has already used $12,500 of special 15-year catch-up capacity in prior years, only $2,500 of lifetime capacity remains, even though the nominal annual maximum is $3,000.

Accurate historical records therefore matter.

Coordinating Two Catch-Up Rules

An employee can potentially qualify for both:

• The special 15-year-service catch-up
• The age-based catch-up

IRS guidance specifies an ordering rule: when both apply, amounts above the basic limit are generally treated first as special 15-year catch-up contributions before applying the age-based catch-up.^[4]

This coordination is important because incorrectly classifying contributions can produce excess deferrals.

Employees eligible for both rules should not assume the limits can simply be added without checking the plan administrator’s calculation.

2026 Contribution Limits at a Glance

The special 15-year catch-up can increase the applicable elective-deferral limit where all requirements are met.^[3][4][5][6]

The Broader Annual-Additions Limit

The employee elective-deferral limit is not necessarily the maximum amount that can enter a 403(b) account.

For 2026, IRS Publication 571 states that the general annual-additions limit increased to:

$72,000.^[6]

Annual additions can include amounts such as:

• Employee contributions
• Employer contributions
• Certain after-tax contributions

subject to compensation and plan rules.

Eligible catch-up contributions can operate above the normal annual-additions framework in specified circumstances.

Employer Contributions

Employers can contribute to 403(b) accounts.^[1][2]

Possible structures can include:

• Matching contributions
• Nonelective employer contributions
• Other plan-defined contributions

Employer contribution formulas vary.

Some organizations provide a match.

Others do not.

The presence of a 403(b) does not imply any particular employer contribution.

Vesting

Employee elective deferrals are generally vested.

Employer contributions can be subject to the plan’s vesting structure, depending on plan type and applicable rules.

Vesting determines when the participant has a nonforfeitable right to certain employer-funded amounts.

A contribution appearing on an account statement is not necessarily fully vested if the plan uses a vesting schedule.

What Investments Can a 403(b) Hold?

The 403(b) investment universe is more structurally specific than a general brokerage account.

IRS and Investor.gov materials identify two traditional funding arrangements:

• Annuity contracts
• Custodial accounts invested in mutual funds^[1][8]

Church-related retirement income accounts can involve additional structures under the tax rules.

A 403(b) is therefore sometimes called a tax-sheltered annuity even when the participant’s actual arrangement uses mutual funds rather than an annuity contract.

Mutual Funds in a 403(b)

A custodial 403(b) account can invest in mutual funds.

Those funds can provide exposure to:

• U.S. stocks
• International stocks
• Bonds
• Balanced portfolios
• Target-date strategies
• Other fund categories

Mutual funds have their own:

• Expense ratios
• Investment objectives
• Risks
• Portfolio holdings

The 403(b) tax wrapper does not change those underlying economics.

Annuities in a 403(b)

403(b) plans have historically used annuity contracts extensively.

An annuity is an insurance-company contract.

Depending on the product, a 403(b) annuity can be:

• Fixed
• Variable
• Structured with other contract features permitted by law and the plan

Annuity contracts can contain:

• Insurance guarantees
• Investment subaccounts
• Administrative expenses
• Mortality and expense charges
• Surrender charges
• Optional riders

The precise economics depend on the contract.

Annuity Does Not Mean Risk-Free

A fixed annuity and a variable annuity can have very different risks.

A variable annuity can hold market-based investment subaccounts whose values fluctuate.

A fixed contract can depend on the claims-paying ability of the insurer for contractual guarantees.

An insurance feature should therefore be separated from:

• Investment performance
• Liquidity
• Fees
• Surrender terms
• Credit exposure to the insurer

The word annuity is not a complete risk description.

Why 403(b) Fees Deserve Attention

403(b) plans can involve several layers of cost.

Potential charges can include:

• Mutual-fund expense ratios
• Annuity contract charges
• Mortality and expense fees
• Administrative fees
• Recordkeeping fees
• Advisory fees
• Surrender charges
• Transfer fees
• Optional rider charges

The Department of Labor emphasizes that retirement-plan fees can reduce long-term account values.^[14]

A tax advantage does not offset every fee automatically.

Surrender Charges

Certain annuity contracts can impose a surrender charge when money is withdrawn or transferred during a specified period.

A hypothetical contract might impose declining charges over several years.

That can affect the cost of:

• Changing vendors
• Moving to another investment
• Taking a distribution
• Rolling assets after leaving employment

A participant comparing 403(b) options should distinguish:

plan rules

from

investment-contract restrictions.

403(b) Vendors

Some 403(b) plans—particularly historically in public-school systems—can offer more than one approved vendor.

Different vendors may offer different:

• Investment menus
• Annuity contracts
• Mutual funds
• Fees
• Advice
• Transfer procedures

A payroll deduction labeled “403(b)” therefore does not tell the participant which underlying contract or vendor economics apply.

403(b) vs. 401(k)

403(b) and 401(k) plans share many characteristics.

Both can:

• Permit salary deferrals
• Offer traditional and Roth contributions
• Permit employer contributions
• Offer age-based catch-ups
• Allow loans if the plan permits
• Be subject to RMD rules
• Support rollovers

But the plans are not identical.

The employee contribution limits look similar.

The employer eligibility and plan structure can differ materially.

ERISA Coverage Can Differ

Not every 403(b) arrangement operates under exactly the same federal benefit-law framework.

Some private nonprofit 403(b) plans are subject to the Employee Retirement Income Security Act, or ERISA.

Certain church plans and certain employee-funded arrangements can fall outside Title I of ERISA if applicable requirements are satisfied.^[14]

This distinction can affect matters such as:

• Fiduciary duties
• Reporting
• Plan administration
• Participant protections

The fact that two workers both have a 403(b) does not mean their plans are legally identical.

Universal Availability

A distinctive 403(b) rule is often described as universal availability.

At a high level, if a 403(b) plan permits one employee to make elective salary deferrals, the plan generally must offer the opportunity to other employees, subject to statutory exclusions and plan rules.^[2]

This differs from some retirement plans that can use broader eligibility restrictions.

The rule is technical and primarily an employer compliance requirement.

For an employee, the practical point is that eligibility for salary deferrals can be broader than eligibility for employer contributions.

403(b) and Automatic Enrollment

Some 403(b) plans can automatically enroll eligible employees and direct contributions to a default investment unless the employee opts out or changes the election.

FINRA notes that certain 401(k) and 403(b) plans established after December 29, 2022 are subject to SECURE 2.0 automatic-enrollment rules beginning in 2025, subject to exceptions.^[9]

Automatic enrollment can increase participation.

It does not mean:

• The default contribution rate is individually optimal.
• The default investment was selected after individualized advice.
• The participant should ignore fees or allocation.

Defaults are administrative tools, not personalized recommendations.

Plan Loans

A 403(b) plan can permit participant loans.

Plans are not required to offer them.

The IRS states that the general maximum plan loan is the lesser of:

• 50% of the participant’s vested account balance, or
• $50,000^[10]

An exception can permit up to $10,000 under certain circumstances if the plan allows it.^[10]

Ordinary plan loans generally must be repaid within five years, except for certain principal-residence loans.

Why a 403(b) Loan Is Not Free Money

A participant can be paying interest back into the retirement account.

But that does not make the loan economically costless.

Potential effects include:

• Investments sold or not purchased while money is borrowed
• Missed market gains
• Repayment obligations
• Loan fees
• Cash-flow pressure
• Tax consequences if repayment rules are violated
• Complications after employment ends

The relevant comparison is not merely:

“Who receives the interest?”

It is:

“What happens to the retirement portfolio and household cash flow while the loan is outstanding?”

Hardship Distributions

Some 403(b) plans can permit hardship distributions if plan and federal requirements are met.

The IRS describes hardship distributions as withdrawals made because of an immediate and heavy financial need under applicable rules.^[11]

Unlike a plan loan, a hardship distribution:

• Is not repaid to the plan
• Permanently removes the distributed assets
• Generally cannot be rolled over
• Can create income-tax consequences
• Can potentially trigger an additional tax on early distributions^[11]

A hardship distribution therefore changes future retirement capital as well as current liquidity.

Early Distribution Risk

Taking retirement assets out early can have two separate costs.

Tax cost

The distribution can be taxable and may be subject to an additional early-distribution tax unless an exception applies.

Compounding cost

The withdrawn assets are no longer inside the account participating in future tax-advantaged investment growth.

The second cost can be easy to overlook because it is not shown as a line item on the withdrawal confirmation.

Required Minimum Distributions

Pre-tax 403(b) balances are generally subject to required minimum distribution rules.

The applicable starting age depends on current federal law and the participant’s birth year.

As with other workplace defined contribution plans, certain participants can sometimes delay RMDs from a current employer’s plan until retirement, subject to statutory rules and ownership restrictions.^[12]

The rules should be checked at the time distributions become relevant because RMD law has changed repeatedly.

Roth 403(b) Lifetime RMDs

Under current law, the IRS states that designated Roth accounts do not have lifetime RMD requirements while the owner is alive.^[12]

That includes designated Roth accounts in 403(b) plans.

Beneficiary distribution rules still apply after death.

This feature should not be confused with the tax treatment of every withdrawal.

Qualified-distribution requirements still matter.

Leaving the Employer

When a participant leaves an employer, several options can be available depending on plan terms and account size.

Possible choices include:

• Leave vested assets in the former employer’s 403(b)
• Roll eligible assets to another employer retirement plan that accepts them
• Roll eligible assets to an IRA
• Take a distribution

Each option can affect:

• Fees
• Investment choices
• Withdrawal rules
• Creditor protections
• Tax consequences
• Administrative convenience

The existence of a rollover option does not make a rollover automatically preferable.

403(b) Rollovers

IRS rollover guidance allows many eligible retirement-plan distributions to be moved to another eligible retirement arrangement.^[13]

A rollover can potentially preserve tax-deferred status.

Possible destinations can include:

• Traditional IRA
• Another eligible employer plan
• Roth IRA or Roth employer account in transactions that can create conversion tax consequences

The tax treatment depends on the source and destination.

Pre-tax assets moved into a Roth account generally require separate tax analysis.

Direct vs. Indirect Rollovers

Direct rollover

Assets move directly from the retirement plan to the receiving eligible account.

Indirect rollover

The distribution is paid to the participant, who must complete a qualifying rollover within the applicable period.

Indirect rollovers can involve:

• Mandatory withholding
• Deadlines
• Tax-reporting complexity
• Risk that part of the distribution becomes taxable

The operational method can therefore matter even when the intended destination is the same.

Contract Exchanges and Transfers Within 403(b) Plans

Some 403(b) participants may be able to move assets between approved contracts or vendors without taking a taxable distribution, depending on plan rules and tax requirements.

These transactions can be more complicated than an ordinary trade inside a brokerage account.

Potential issues include:

• Whether the receiving vendor is approved
• Information-sharing agreements
• Surrender charges
• Contract restrictions
• Plan document requirements

A transfer that is permitted by tax law can still be economically expensive if the existing contract imposes a surrender charge.

Investment Choice Matters More Than the Label

Consider two hypothetical workers.

Employee A

403(b) holdings:

• Broad U.S. equity index fund
• International equity fund
• Bond index fund

Employee B

403(b) holdings:

• One high-cost variable annuity
• Concentrated equity subaccounts
• Significant surrender charges

Both have a 403(b).

The account label does not tell us:

• Diversification
• Cost
• Liquidity
• Risk
• Expected return

That information comes from the investments and contracts.

403(b) and Target-Date Funds

Many modern 403(b) menus include target-date funds.

A target-date fund can automate:

• Asset allocation
• Rebalancing
• Glide-path changes over time

That can simplify plan investing.

But—as explained in What Is a Target-Date Fund?—same-date funds can differ in:

• Risk
• Fees
• Underlying holdings
• Glide path

A 2055 target-date fund inside a 403(b) should still be evaluated as an investment.

Fees and Long Time Horizons

Retirement plans can remain invested for decades.

That magnifies the importance of recurring fees.

Suppose two hypothetical investment arrangements produce identical gross performance.

One has annual costs of 0.20%.

Another has annual costs of 1.50%.

The higher-cost arrangement leaves less capital invested each year.

The effect then compounds.

This does not mean the cheapest product is automatically best.

It means a higher-cost product needs to be understood in terms of what additional feature or service the cost supports.

What to Look for in an Annuity Contract

If a 403(b) uses an annuity, useful information can include:

• Insurance company
• Contract type
• Guaranteed rate, if applicable
• Investment subaccounts
• Mortality and expense charges
• Administrative fees
• Surrender schedule
• Rider fees
• Withdrawal restrictions
• Annuitization provisions
• Beneficiary features

A contractual guarantee is only as meaningful as:

• The precise guarantee
• The contract terms
• The insurer’s claims-paying ability

Investment-market risk can remain in variable subaccounts.

What to Look for in Mutual Funds

If the 403(b) uses mutual funds, useful information can include:

• Investment objective
• Asset class
• Benchmark
• Expense ratio
• Share class
• Portfolio turnover
• Diversification
• Historical risk
• Manager or index methodology

Two funds with similar names can have different costs and portfolio exposures.

403(b) vs. IRA

A 403(b) and IRA can coexist.

Participation in a workplace 403(b) can affect traditional IRA deduction eligibility depending on income and tax circumstances.

403(b) vs. 457(b)

Public-sector and nonprofit employees can sometimes encounter both 403(b) and 457(b) plans.

The names sound similar.

The rules are not identical.

Governmental 457(b) plans have their own contribution, catch-up and distribution rules.

One important structural point is that an employee eligible for both a 403(b) and a governmental 457(b) may encounter separate statutory deferral frameworks, subject to the specific tax rules.

The two plans should not be treated as interchangeable.

A separate ROIStreet guide covers 457(b) plans.

If an Employee Has a 401(k) and a 403(b)

The elective-deferral limit generally must be coordinated across 401(k) and 403(b) plans for the same individual.

An employee cannot ordinarily contribute the full basic Section 402(g) amount independently to a 401(k) and then another full basic amount to a 403(b) without considering the shared limit.^[3][6]

This can matter for:

• Employees with multiple jobs
• Adjunct faculty
• Workers changing employers during the year
• Employees who have both nonprofit and private-sector employment

Payroll systems at separate employers may not automatically know about contributions made elsewhere.

The participant may need to monitor the combined amount.

Contribution Errors

Exceeding applicable limits can create tax and correction problems.

Potential causes include:

• Multiple employers
• Multiple 403(b) vendors
• Incorrect catch-up classification
• Improper use of the 15-year rule
• Failure to coordinate traditional and Roth deferrals

The special 15-year catch-up is particularly record-intensive because prior contributions and years of service affect eligibility.^[4]

Historical records matter.

Beneficiary Designations

A 403(b) account generally includes beneficiary designations.

These can determine who receives the account after the participant’s death, subject to plan and applicable spousal rules.

Beneficiary designations can interact with:

• Marriage
• Divorce
• Estate documents
• Trusts
• Inherited-account distribution rules

A retirement beneficiary form should not be assumed to update automatically when a will changes.

Account Review

A periodic 403(b) review can focus on:

• Contribution rate
• Traditional vs. Roth election
• Employer contribution formula
• Vesting
• Investment allocation
• Fund expenses
• Annuity contract charges
• Surrender periods
• Beneficiary designation
• Outstanding loans
• Vendor changes
• Whether catch-up eligibility has changed

A review does not imply frequent trading.

It means the account’s rules and the participant’s circumstances can change over time.

Common Misconceptions

"403(b) plans are only for teachers."

No. Certain nonprofit employees and ministers can also be eligible.^[1][2]

"A 403(b) is an investment."

No. It is a tax-advantaged employer retirement-plan structure.

"403(b) and 401(k) plans are identical."

No. They share many contribution and tax concepts but differ in eligible employers, plan structures and special rules.

"Tax-sheltered means protected from investment loss."

No. Tax treatment does not guarantee market value.

"Everyone with 15 years of work gets another $3,000."

No. The special catch-up is available only under qualifying 403(b) plans and is limited by a statutory formula and $15,000 lifetime cap.^[4]

"The 15-year catch-up and age-50 catch-up can always just be added together."

Not without applying the IRS coordination rules.^[4]

"Traditional and Roth each get a separate $24,500 limit."

No. They share the applicable basic elective-deferral limit.

"All 403(b) plans offer the same investments."

No. Vendors, contracts and plan menus can differ substantially.

"An annuity guarantees my whole 403(b)."

No. Guarantees are contract-specific, and market-based components can still lose value.

"Rolling a 403(b) to an IRA is always better."

No. Fees, investment choices, legal protections and withdrawal rules can differ.

A plan can permit loans. The general federal limit is the lesser of 50% of the vested balance or $50,000, subject to applicable exceptions and plan terms.^[10]

Can I take a hardship withdrawal?

Some plans permit hardship distributions under federal and plan rules. They are not loans and generally cannot be rolled over.^[11]

Can I roll a 403(b) into an IRA?

Many eligible distributions can be rolled into an IRA or other eligible plan, subject to rollover and tax rules.^[13]

Is a 403(b) safer than a 401(k)?

Not as a general rule. Investment risk depends principally on the holdings, fees, diversification and plan features rather than the tax-code section number.

A 403(b) Research Framework

When reviewing a 403(b), useful questions include:

1. Is the employer eligible to sponsor the plan?
2. What employee contributions are permitted?
3. Does the plan offer traditional, Roth or both?
4. What employer contributions are available?
5. What vesting schedule applies?
6. What 2026 contribution limits apply to the participant?
7. Is an age-based catch-up available?
8. Does the plan permit the special 15-year catch-up?
9. If so, has the formula been calculated using complete service and contribution history?
10. What vendors and investment arrangements are offered?
11. Are the holdings mutual funds, annuity contracts or both?
12. What are the total fees?
13. Are surrender charges or transfer restrictions present?
14. How diversified is the portfolio?
15. Does the plan allow loans or hardship distributions?
16. What RMD rules will apply?
17. Are beneficiary designations current?
18. If employment ends, how do the plan, IRA and other rollover options compare?

These questions organize the account analysis without determining a contribution amount, vendor or investment strategy for a particular reader.

The Bottom Line

A 403(b) is a tax-advantaged employer retirement plan designed primarily for workers in public education, qualifying nonprofit organizations and certain ministerial roles.

It shares many features with a 401(k):

• Payroll contributions
• Traditional and Roth tax treatment
• Employer contributions
• Age-based catch-ups
• Investment choices
• Loans in plans that permit them
• Rollover options

But 403(b) plans also have distinctive features.

The most notable is the special 15-year-service catch-up, which can allow certain qualifying long-service employees to defer additional money under a formula with a $15,000 lifetime limit.^[4]

The plan can also use investment structures with a long history in the 403(b) market, including annuity contracts and mutual-fund custodial accounts.

For 2026, the basic elective-deferral limit is $24,500, the standard age-50 catch-up is $8,000, and the special age-60-through-63 catch-up is $11,250.^[3][5]

Those tax limits matter.

But they do not answer the investment question.

The useful framework is:

What plan rules apply, what contribution opportunities exist, what investments and contracts are actually being used, what do they cost, and what risks remain after the tax advantages are considered?

That separates the 403(b) wrapper from the financial assets inside it.
