A 403(b) is the workplace retirement plan used by many public schools, universities, nonprofit hospitals, charities, and other eligible tax-exempt organizations.
It works a lot like a 401(k), but there is one difference I would pay close attention to: the investment menu.
Some 403(b) plans offer simple, low-cost funds. Others rely heavily on annuity contracts that can come with higher costs or withdrawal restrictions. The account itself is not the problem. What matters is what your employer actually puts inside it.
My order of operations is simple: check the employer match first, then inspect the investment options, fees, and restrictions before deciding how much more to contribute.
Key takeaways
- The 403(b) employee contribution limit is $24,500 in 2026.
- Employees age 50+ may qualify for catch-up contributions, with a higher limit for ages 60 to 63.
- Some long-tenured employees can also use a special 15-year 403(b) catch-up.
- A 403(b) can hold mutual funds or annuity contracts. Compare total costs and restrictions, not just the investment name.
- If you also have a governmental 457(b), it has a separate contribution limit.
How a 403(b) works
Eligible employees can contribute directly from their paycheck.
With a traditional 403(b), contributions generally reduce current taxable income and withdrawals are generally taxed later.
A Roth 403(b) uses after-tax contributions instead. Qualified withdrawals can be tax-free.
Your employer may also contribute or offer a match.
If there is a meaningful employer match, I would usually start by contributing enough to capture it before worrying about whether another account has a slightly lower fund expense ratio.
403(b) contribution limits for 2026
The employee elective-deferral limit is $24,500 in 2026. The standard age-50 catch-up is another $8,000. Participants who reach ages 60 through 63 during 2026 can instead use the higher $11,250 catch-up.
| Contribution | 2026 limit |
|---|---|
| Standard employee deferral | $24,500 |
| Age 50+ catch-up | $8,000 |
| Ages 60 to 63 catch-up | $11,250 |
| Special 15-year catch-up | Up to $3,000 |
| General annual-additions limit | $72,000 or 100% of includible compensation, if lower |
The $72,000 annual-additions limit generally includes employee and employer contributions, but age-based catch-up contributions can sit above that limit.
There is also a new 2026 rule for some higher-paid participants. If your plan offers Roth contributions and your prior-year wages from that employer exceeded $150,000, age-based catch-up contributions generally have to be made as Roth contributions.
Your plan still has to permit the relevant contribution feature.
The special 15-year catch-up
This is one feature a 401(k) does not have.
Certain employees with at least 15 years of service with the same qualifying employer can increase their 403(b) deferral by up to $3,000 for the year if the plan allows it.
But 15 years of service does not automatically give you another $3,000.
The IRS calculation also considers prior use of the catch-up and previous contributions. There is a $15,000 lifetime cap.
If both the 15-year rule and an age-based catch-up apply, IRS rules treat the extra contributions under the 15-year provision first.
This is one of the few areas where I would let the plan administrator do the calculation rather than trying to estimate the limit yourself.
403(b) vs. 401(k)
For most workers, the basic retirement mechanics are similar.
| Feature | 403(b) | 401(k) |
|---|---|---|
| 2026 employee limit | $24,500 | $24,500 |
| Traditional contributions | Yes | Yes |
| Roth contributions | If offered | If offered |
| Employer contributions | Possible | Possible |
| Age-based catch-ups | Yes | Yes |
| Special 15-year catch-up | Possible | No |
| Typical employers | Public schools and eligible nonprofits | Private-sector employers |
One detail matters if you have access to more than one workplace plan: a 401(k) and 403(b) generally share the same employee elective-deferral limit.
You normally cannot put $24,500 into each and call it $49,000 of separate employee deferrals.
A governmental 457(b) is different.
The part I would check first: investment fees
This is where a mediocre 403(b) can become expensive.
An ordinary mutual fund can have an expense ratio. The plan itself may also charge administrative fees. An annuity can add contract expenses, insurance costs, optional rider fees, or surrender charges.
The SEC warns that variable annuities can include mortality and expense charges, administrative costs, underlying fund expenses, and surrender charges that reduce returns.
That does not mean:
annuity = bad
index fund = good
That is too simplistic.
An annuity may offer guarantees or income features you genuinely want. But if you are paying extra for features you do not need, I would question the product.
What I would actually compare
Before choosing an investment, look at:
- total ongoing costs;
- plan administration fees;
- surrender charges or transfer restrictions;
- what the investment owns;
- any guarantee or insurance feature;
- whether a simpler diversified alternative exists.
I would not use a magic threshold such as “anything below 0.20% is good.”
If two funds do essentially the same job, lower cost is a strong advantage. If the products do different things, compare the entire package.
Should you use an IRA instead?
Not automatically.
This is where generic retirement-account checklists often become too rigid.
If your 403(b) has a good employer match and reasonable investments, it can be an excellent place to save. Its employee contribution limit is much larger than an IRA’s.
If your plan is expensive or restrictive, an IRA may give you more control over investments. But an IRA has a lower contribution limit, and Roth IRA eligibility can depend on income.
So I would not use:
match → Roth IRA → 403(b)
as a universal rule.
Instead ask:
Where should my next dollar go?
Compare:
- employer match;
- current and future tax treatment;
- investment costs;
- investment choices;
- liquidity;
- IRA eligibility;
- how much you want to save.
That framework is more useful than pretending one account always wins.
Traditional or Roth 403(b)?
I would not decide this from your tax bracket alone.
A traditional contribution is more attractive when the current tax deduction is particularly valuable.
A Roth contribution becomes more attractive when paying tax today looks reasonable and tax-free qualified withdrawals later are valuable to you.
The problem is that nobody knows their exact future tax rate.
Future income, tax law, retirement spending, pensions, Social Security, and other accounts can all change the answer.
For some people, splitting contributions between traditional and Roth is a reasonable middle ground rather than betting everything on one tax prediction.
If you also have a governmental 457(b)
This is where public-sector retirement planning gets more interesting.
A governmental 457(b) has a separate $24,500 employee limit in 2026. Someone eligible for both a 403(b) and governmental 457(b) can potentially contribute to both limits.
A governmental 457(b) also has an unusual withdrawal advantage: distributions generally are not subject to the 10% additional early-distribution tax, although money rolled into the plan from certain other retirement accounts can still be treated differently.
That can make the 457(b) attractive for someone who expects to leave work before age 59½.
But I still would not automatically put the 457(b) ahead of the 403(b). Compare the actual fees, investment menu, employer contributions, and withdrawal rules first.
And make sure it is a governmental 457(b). Nongovernmental plans work differently.
A quick warning for TIAA Traditional
If your 403(b) contains TIAA Traditional, check the specific contract before assuming you can move the money whenever you want.
Some contracts allow more flexible withdrawals, while others can require distributions or transfers over 10 annual installments or 84 monthly installments. Some lump-sum withdrawals may also involve surrender charges.
That liquidity tradeoff is part of the product.
I would not choose or reject TIAA Traditional based on the credited interest rate alone.
What happens when you leave your employer?
You generally have several possible options, depending on the plan:
- leave the account where it is;
- roll eligible money into a new employer plan;
- roll eligible money into an IRA;
- take a distribution.
A direct rollover generally avoids the mandatory 20% federal withholding that applies when an eligible employer-plan distribution is paid directly to you.
I prefer direct rollovers when the goal is simply to move retirement money between eligible accounts because they remove an unnecessary tax-withholding complication.
But I would not automatically roll every old 403(b) into an IRA. Compare the old plan, new plan, and IRA before moving anything.
Fees and investments matter, but so can withdrawal rules and other plan protections.
Frequently asked questions
Can I have both a 403(b) and a Roth IRA?
Yes.
They have separate contribution limits. Access to a 403(b) does not by itself prevent you from contributing to a Roth IRA, although Roth IRA income limits still apply.
Are annuities in a 403(b) bad?
No.
Some are expensive or restrictive. Others provide guarantees or income features an investor may actually want.
Read the costs and withdrawal terms instead of judging the product category alone.
Can a 403(b) offer loans?
Yes, if the plan permits them.
The plan does not have to offer loans, so check the plan document before assuming one is available.
Is a 403(b) always covered by ERISA?
No.
Governmental plans and most church plans are generally outside ERISA, while many private nonprofit employer plans can be covered.
The exact protection depends on the type of plan and employer, so do not assume every 403(b) follows the same legal framework.
The bottom line
A good 403(b) does not need to be complicated.
If your employer matches contributions and the plan gives you diversified investments at reasonable costs, I would use it without overthinking the fact that it is a 403(b) rather than a 401(k).
What deserves scrutiny is the investment lineup.
Check the match first. Then check fees, what each investment owns, and any withdrawal restrictions. Be especially careful before locking money into an annuity contract you do not understand.
The biggest mistake is not having a 403(b). It is treating every product inside the 403(b) as equally good just because your employer put it on the menu.
