A 403(b) is an employer-sponsored retirement plan commonly available to employees of public schools, colleges and universities, certain nonprofit organizations, and churches. It allows eligible employees to save for retirement through payroll deductions while receiving tax advantages.
Depending on the plan, contributions may be made to a traditional 403(b), a Roth 403(b), or both. The money is then invested according to the options offered by the plan and can potentially grow over time.
Understanding contribution limits, taxes, investment choices, withdrawals, and rollover options can help you make better decisions about your retirement savings.
What Is a 403(b)?
A 403(b) is a tax-advantaged retirement plan established under Section 403(b) of the Internal Revenue Code. It is designed primarily for employees of certain tax-exempt organizations, public schools, churches, and other qualifying employers.
A 403(b) works much like a workplace 401(k) in several important ways. You can generally contribute through payroll deductions, investments can grow within the account without annual taxation on investment gains, and some employers contribute additional money to employees’ accounts.
The main difference is who typically offers the plan. A 401(k) is generally associated with private-sector employers, while a 403(b) is commonly offered by qualifying educational, nonprofit, religious, and certain public-sector organizations.
A 403(b) is also not itself a single investment. Think of the 403(b) as the retirement plan or account structure. The money inside it may be invested in options such as mutual funds or annuity contracts, depending on the employer’s plan.
How Does a 403(b) Work?
The basic process is straightforward:
Paycheck → contribution → 403(b) account → investment → potential growth → retirement withdrawal
You choose how much of your eligible pay to contribute, subject to applicable limits and your plan’s rules. Your employer generally deducts the elected amount from your paycheck and sends it to the 403(b).
For example, suppose an employee earns $60,000 per year and elects to contribute 5% of pay. That equals $3,000 per year, or $250 per month, before considering the tax treatment and payroll schedule.
The contribution is then allocated according to the investment choices selected by the employee. The account balance can rise or fall based on investment performance, contributions, fees, and any employer contributions.
Your particular plan determines which features are available. Employer matching, Roth contributions, loans, hardship distributions, investment choices, fees, and certain withdrawal provisions are not necessarily identical across all 403(b) plans.
Who Can Have a 403(b)?
403(b) plans are generally available through qualifying employers and organizations rather than being individually opened by anyone who wants one.
Eligible organizations can include:
- Public schools
- Certain colleges and universities
- Organizations that qualify under Section 501(c)(3)
- Certain churches and church-related organizations
- Certain ministers and qualifying religious workers
- Certain qualifying hospital and health-related organizations
Eligibility can depend on both the employer and the terms of its plan. If you work for a school, university, nonprofit, hospital, or religious organization, check your benefits documents or ask the plan administrator whether you are eligible.
Traditional vs. Roth 403(b): What’s the Difference?
A 403(b) may offer traditional contributions, Roth contributions, or both.
| Feature | Traditional 403(b) | Roth 403(b) |
|---|---|---|
| Contributions | Generally pre-tax | After-tax |
| Tax benefit | Generally received before retirement | Generally received during qualified withdrawals |
| Investment growth | Tax-deferred | Generally tax-free for qualified distributions |
| Qualified retirement withdrawals | Generally taxable | Generally tax-free |
| Availability | Depends on the plan | Depends on the plan |
Traditional 403(b)
Traditional contributions are generally made before federal income taxes are applied to the contributed amount. This can reduce current taxable income, although other payroll taxes may still apply.
You generally pay ordinary income tax when taxable money is withdrawn later.
For example, if you contribute $5,000 to a traditional 403(b), that contribution generally receives its tax benefit in the year it is made. The eventual taxable distribution is generally included in income.
Roth 403(b)
Roth 403(b) contributions are made with after-tax money. You do not generally receive an upfront federal income-tax deduction for the contribution.
The potential advantage comes later. Qualified distributions from a Roth 403(b) can generally be received tax-free. To generally be qualified, the Roth account must satisfy the applicable five-year rule and the distribution must occur after age 59½, after death, or because of disability.
The better choice depends on your circumstances, including your current and expected future tax situation. Some employees choose to divide contributions between traditional and Roth accounts rather than relying entirely on one tax treatment.
How Much Can You Contribute to a 403(b) in 2026?
For 2026, the basic employee elective-deferral limit for a 403(b) is $24,500. Employees age 50 or older by the end of the year can generally make an additional $8,000 catch-up contribution, bringing the potential employee contribution to $32,500.
Employees who turn 60, 61, 62, or 63 during 2026 may qualify for the higher SECURE 2.0 catch-up limit of $11,250 instead of the regular $8,000 catch-up limit. That can allow eligible participants to contribute up to $35,750 in 2026 through the basic limit plus the enhanced catch-up.
| 2026 contribution category | Limit |
|---|---|
| Basic employee contribution | $24,500 |
| Age 50+ catch-up | $8,000 |
| Age 60-63 enhanced catch-up | $11,250 |
| Basic + age 50 catch-up | $32,500 |
| Basic + age 60-63 enhanced catch-up | $35,750 |
There is also a special 15-year service catch-up for certain employees who have at least 15 years of service with the same eligible employer, if the plan permits it.
The calculation is more complicated and depends on previous contributions and years of service. The additional amount can be as much as $3,000 in a year, subject to the applicable lifetime and other limits.
The overall annual-additions limit for a 403(b), which generally includes employee and employer contributions, is $72,000 in 2026 or 100% of includible compensation, whichever is less, subject to the rules and exceptions that apply. Catch-up contributions are treated separately from this annual-additions limit.
If you participate in more than one workplace retirement plan, additional coordination rules can apply to employee elective deferrals.
Does a 403(b) Have an Employer Match?
It can, but an employer match is not automatic.
Some employers contribute a percentage of an employee’s contribution. For example, a hypothetical employer might match 50% of employee contributions up to the first 6% of salary.
If an employee earns $60,000 and contributes 6%, the employee contributes $3,600. Under that hypothetical matching formula, the employer would contribute another $1,800.
Some employers may instead make non-elective contributions, meaning they contribute money even when an employee does not make a contribution. Vesting rules may also determine when employer contributions fully belong to the employee.
Always check your plan’s matching formula, eligibility requirements, and vesting schedule rather than assuming every 403(b) has the same arrangement.
How Are 403(b) Funds Invested?
The investment choices depend on the specific plan.
Common options can include:
- Mutual funds
- Target-date funds
- Annuity contracts
- Bond funds
- Stock funds
- Other investment options permitted by the plan
This distinction is important: a 403(b) is the retirement plan, while the mutual fund or annuity is an investment that may be held inside the plan.
Investment menus can vary significantly between employers. One 403(b) might offer a broad selection of low-cost funds, while another may have a narrower menu or insurance-based products.
Fees also matter. Depending on the plan, you may encounter investment expense ratios, administrative fees, recordkeeping costs, or charges associated with particular annuity products. Compare the actual fees and investment choices in your plan documents before making a decision.
When Can You Withdraw Money From a 403(b)?
A 403(b) is intended for retirement, so access before retirement can be restricted.
Generally, distributions from a 403(b) can become available after certain qualifying events, such as:
- Reaching age 59½
- Leaving the employer
- Becoming disabled
- Death
- Certain other events or circumstances permitted under the applicable rules and plan
The exact availability of a distribution depends on federal tax rules and the terms of the plan.
What happens if you withdraw money early?
A taxable distribution taken before age 59½ may be subject to ordinary income tax and an additional 10% federal tax, unless an exception applies.
Some exceptions can eliminate the additional 10% tax, but they do not necessarily make the distribution income-tax-free.
This distinction matters. Avoid assuming that an exception to the 10% additional tax also eliminates ordinary income tax.
Can you take a loan from a 403(b)?
Some 403(b) plans permit participant loans, but not all do. If your plan offers loans, the plan determines the applicable terms, including borrowing limits, repayment requirements, and interest.
A loan can have consequences if you leave your employer or fail to follow the repayment requirements. Because of these potential complications, a plan loan should not be treated as automatically equivalent to ordinary access to your retirement savings.
What is a hardship withdrawal?
A plan may permit hardship distributions for certain qualifying financial needs, but hardship rules are plan-specific and can be complex.
A hardship distribution permanently removes money from your retirement account and may create taxes or additional tax depending on the circumstances. It is therefore different from borrowing money through a plan loan.
Does a 403(b) Have Required Minimum Distributions?
Traditional 403(b) accounts are generally subject to required minimum distribution, or RMD, rules.
Under current federal rules, RMDs generally begin when you reach age 73, although the precise required beginning date can depend on the applicable retirement-plan rules and your employment status.
For workplace retirement plans, the rules can allow certain employees to delay RMDs until retirement, subject to the applicable requirements.
A major distinction applies to designated Roth accounts in workplace plans. Under current rules, the owner of a designated Roth account in a 403(b) does not have to take lifetime RMDs while alive.
Because RMD rules can change and can involve special circumstances, verify the applicable requirement for your account before the year you expect RMDs to begin.
What Happens to a 403(b) When You Leave Your Job?
Leaving an employer does not necessarily mean you have to cash out your 403(b).
Depending on your circumstances and the plans involved, common options include:
| Option | What it means |
|---|---|
| Leave it in the existing plan | Keep the account where it is if the plan permits former employees to maintain the balance |
| Move to a new employer plan | Roll the money into another eligible workplace retirement plan if that plan accepts rollovers |
| Roll it to an IRA | Transfer eligible funds to an IRA, subject to rollover rules |
| Take a cash distribution | Receive the money directly, potentially creating income tax and an additional tax |
A direct rollover can generally help you avoid current taxation that could occur when retirement money is paid directly to you. Rollovers also have detailed rules, particularly when moving money between traditional and Roth accounts.
There is no universal best option. Consider investment choices, fees, account consolidation, withdrawal rules, creditor considerations, and the features available in the destination account.
403(b) vs. 401(k): What’s the Difference?
Both plans are employer-sponsored retirement arrangements with many similar tax features, but they are generally designed for different types of employers.
| Feature | 403(b) | 401(k) |
|---|---|---|
| Common employers | Public schools, qualifying nonprofits, churches and similar organizations | Primarily private-sector employers |
| Employee contributions | Subject to annual IRS limits | Subject to annual IRS limits |
| Traditional option | Generally available | Generally available |
| Roth option | May be available | May be available |
| Employer contributions | May be available | May be available |
| Investment choices | Depend on the plan | Depend on the plan |
| Catch-up contributions | Available under applicable rules | Available under applicable rules |
The two plans have many overlapping federal rules, including the 2026 basic elective-deferral limit of $24,500.
Neither plan is automatically better. The quality of a particular plan can depend on its investment menu, fees, employer contributions, withdrawal provisions, and other features.
Advantages and Disadvantages of a 403(b)
Advantages
- Tax advantages: Traditional contributions can provide an upfront tax benefit, while qualified Roth withdrawals can provide tax-free retirement income.
- Payroll automation: Contributions can be deducted automatically from each paycheck, making consistent retirement saving easier.
- High contribution limits: The 2026 employee contribution limit is substantially higher than the annual IRA contribution limit.
- Potential employer contributions: Some employers provide matching or other contributions that can increase retirement savings.
- Catch-up opportunities: Older employees may have access to additional contribution opportunities, including the age-based catch-up and, for qualifying employees, the special 15-year service provision.
Disadvantages
- Investment choices vary: Your plan may offer fewer choices than an IRA or another retirement account.
- Fees can differ: Two 403(b) plans can have very different investment and administrative costs.
- Early withdrawals can be expensive: Taxes and additional taxes may apply when money is withdrawn before retirement without a qualifying exception.
- Plan features are not universal: Roth contributions, loans, hardship distributions, employer matching, and other provisions depend on the plan.
What Is the 15-Year Rule for a 403(b)?
The 15-year rule is a special catch-up provision available to certain long-term employees of eligible 403(b) organizations.
If your plan permits it and you have at least 15 years of service with the same eligible employer, you may be able to contribute more than the normal elective-deferral limit. The calculation considers your prior contributions and other factors, so simply working for an employer for 15 years does not automatically mean you can contribute an additional $3,000 every year.
The IRS limits this special catch-up and requires specific calculations.
Frequently Asked Questions About 403(b) Plans
Is a 403(b) the same as a savings account?
No. A 403(b) is a retirement plan. The money inside the plan is generally invested in available investment options, so the balance can rise or fall with investment performance.
Can I have a 403(b) and an IRA?
Yes, it is generally possible to participate in a workplace 403(b) and also contribute to an IRA. However, separate IRA contribution and tax-deduction rules apply. Your workplace plan participation can affect whether contributions to a traditional IRA are deductible, depending on income and filing status.
Can I lose money in a 403(b)?
Yes. A 403(b) is not automatically protected from investment losses. The value can decline when the investments inside the account decline. The level of investment risk depends on what you choose and what your plan offers.
Can I roll over my 403(b)?
Eligible distributions from a 403(b) can generally be rolled into another eligible retirement arrangement, including certain IRAs and employer retirement plans. Roth money has additional rules, so the destination account must be appropriate for the type of funds being rolled over.
Should I choose a traditional or Roth 403(b)?
There is no single choice that is right for everyone. A traditional 403(b) generally gives you the tax benefit now and taxes distributions later. A Roth 403(b) generally requires taxes on contributions now but can provide tax-free qualified distributions later.
Your current tax rate, expected future tax rate, retirement income needs, and the options offered by your plan can all matter.
Conclusion
A 403(b) is a workplace retirement plan designed primarily for employees of qualifying schools, nonprofit organizations, churches, and similar employers. It can provide valuable tax advantages, automatic payroll saving, employer contributions, and relatively high annual contribution limits.
The most important details are not identical for every participant. Your employer’s plan determines the available investments, fees, matching contributions, Roth availability, loans, and several other features.
Federal rules determine contribution limits, taxation, withdrawals, and other requirements, but the specific plan document determines how those rules operate in your workplace.
If you have access to a 403(b), review your plan’s investment choices, fees, employer contribution formula, tax options, and withdrawal provisions before deciding how to use it. For personalized tax or investment decisions, consider consulting a qualified tax or financial professional.
