2026 Contribution Limits for University Retirement Plans: 403(b),457(b), 401(a) Explained

Quick answer (what matters most):

• 403(b) limit (2026): $24,500; 457(b) limit (2026): $24,500.

• Catch-up (50+): $8,000; higher catch-up (60–63): $11,250 if your plan adopts it.

• Common priority: required 401(a) structure → 403(b) baseline → 457(b) → Roth/pre-

tax refinement.

Trying to max out your University retirement accounts in 2026 can feel surprisingly

complicated, especially when your plan includes more than one bucket (401(a), 403(b), and sometimes 457(b) & 403(b) SRA) and the rules aren’t explained in one place.

This post is built to simplify that. For University employees using TIAA or Fidelity, we’ll

cover the 2026 contribution limits, what catch-up contributions mean (and who can use

them), and a clear prioritization approach that works well for most people.

The four buckets at a glance

Bucket	Who funds it	2026 Limit	Notes
401(a)	Employer (and sometimes mandatory employee match)	Set by plan	Mandatory at most public Universities; employer typically contributes 8–12% of salary
403(b)	Basic Employee elective deferrals	Counted in 403(b) family limit	Default-enrollment account, usually starting at 5%
403(b) SRA	Employee elective deferrals	Counted in 403(b) family limit	The "extra" voluntary bucket. Where additional contributions go after the basic 403(b) is funded
403(b) FAMILY combined		$24,500	The basic 403(b) and the SRA share a single combined elective deferral limit
457(b)	Employee elective deferrals	$24,500	Completely separate limit; can run alongside the 403(b) family

The 403(b) family: how the Basic and SRA work together

This is the section that most explanations get wrong, and it's the most important one for

University employees.

Why your University has two 403(b) accounts

When you started at the University, your benefits enrollment likely opened two

separate 403(b) accounts under your name:

1. The Basic 403(b): often default-enrolled at 5% of salary. This is the

foundation contribution that flows automatically every paycheck.

2. The 403(b) Supplemental Retirement Account (SRA): a voluntary account

where you can elect to contribute additional dollars on top of the basic 5%.

The SRA is sometimes labeled differently across institutions: Supplemental

Retirement Account, Voluntary Tax-Deferred Account, 403(b) Voluntary, or Group

Supplemental Retirement Annuity (GSRA) if it's structured as a TIAA annuity

contract. Same idea, different names.

How the limit applies across both accounts

The IRS treats the basic 403(b) and the SRA as a single combined elective deferral

limit. You cannot contribute $24,500 to each. The $24,500 cap is the total across

both.

If your basic 403(b) is auto-deducting 5% of a $100,000 salary, that's $5,000 going

into the basic 403(b). To max out the family, you'd direct an additional $19,500 into

your SRA — either as a flat dollar amount or as a percentage of salary — bringing

the family total to $24,500.

Why both accounts exist if they share a limit

The structure exists for plan administration reasons — different vesting schedules,

different default investment choices, sometimes different match treatment,

sometimes different distribution rules. The basic 403(b) is often where employer

matching contributions land if your University offers a match; the SRA is purely

employee voluntary.

What employees commonly miss

The most common mistake we see: an employee assumes their 5% basic

contribution is "their 403(b)" and never opens or funds the SRA. They walk away

from the other $19,500 of tax-advantaged savings space every year. Over a 30-year

career, this is a six-figure mistake.

The second most common mistake: an employee tries to max out their 403(b) by

directing $24,500 into the basic 403(b), not realizing the basic account may be

capped by plan rules at a lower percentage of salary. The SRA exists specifically to

absorb the dollars beyond the basic limit.

How to enroll in your SRA

Log into your TIAA or Fidelity NetBenefits portal, look for "Supplemental Retirement Account" or "403(b) Voluntary," and elect a contribution amount. If you can't find it, your University HR or benefits office will direct you to the enrollment form.

The 457(b): your second separate $24,500 bucket

The 457(b) Deferred Compensation Plan is the second voluntary employee bucket, with its own completely separate $24,500 limit in 2026. You can max the 403(b) family AND max the 457(b) in the same year. This is the single biggest savings advantage University employees have over corporate workers, who typically have only a 401(k) limit of $24,500 to work with.

The 457(b) has three structural advantages worth knowing:

• Separate limit. Doubles your voluntary savings space.

• No early withdrawal penalty. Unlike 403(b) and 401(a), distributions from a governmental 457(b) after separation from service are not subject to the 10% early withdrawal penalty regardless of age. This makes the 457(b) a uniquely flexible account for early or phased retirement.

• Special last-three-years catch-up. Employees within three years of their plan's normal

retirement age can contribute up to double the standard limit ($49,000 in 2026) instead of using the age-50 catch-up. You cannot use both the special last-three-years catch-up and the age-50 catch-up in the same year.

The 401(a): the employer-funded layer on top

Your 401(a) is the mandatory plan where your University deposits its contributions. Most

Universities contribute somewhere between 8% and 12% of salary into your 401(a), and

the employee may also be required to make a mandatory matching contribution.

The 401(a) is governed by the Section 415(c) annual additions limit of $70,000 in 2026,

which covers the total of employer and employee contributions to the 401(a). Most

University employees are nowhere near this limit because employer rates are in the 8–12% range, but it sets the ceiling.

What this means in practice: if your salary is $120,000 and your University contributes 10% of salary to your 401(a), that's $12,000 in employer money on top of whatever you contribute to the 403(b) family and 457(b).

Can I max both a 403(b) and a 457(b) in 2026?

Often, yes. Many University employees can contribute the full 403(b) amount and also the full 457(b) amount because they are separate plan types. That’s one of the reasons higher education retirement plans can be unusually powerful.

The caveat is that plan rules vary by institution and payroll systems can be… creatively

configured. So the smart move is confirming which buckets you have and whether your

457(b) is available and eligible.

Catch-up contributions at age 50+

If you’re 50 or older by the end of the year and your plan allows catch-ups, you may be able to contribute an additional $8,000 in 2026. For many people, catch-ups are the difference between “I hope I’m okay” and “I can see the finish line.”

A small warning: if you can’t comfortably use the full catch-up, don’t force it. The goal is

consistency, not panic-funding.

The higher catch-up for ages 60–63

If you’re 60 to 63, 2026 has a higher catch-up amount listed at $11,250, but it depends on plan adoption. If your University plan adopts it and you’re eligible, it can be a meaningful accelerator.

What about the 401(a) limit?

401(a) plans are often structured around employer contributions and plan-specific rules. In many University plans, employees treat the 401(a) as the employer bucket and then decide how much to personally contribute through the 403(b) and 457(b). If your 401(a) is confusing, you’re not alone. It’s plan-specific by design.

A contribution order that works for most University employees

Here’s the practical order we often use as a starting point:

Priority	Where dollars go first	Why it helps
1	Any required plan contributions (often tied to 401(a) rules)	Stay aligned with plan rules and employer structure
2	403(b)	Core retirement savings bucket
3	403(b) SRA or 457(b) (if available)	Extra savings capacity that can speed up progress
4	Roth vs pre-tax decisions	Optimize after the baseline is set

How to make this easier in real life

Here’s the part people don’t say out loud: the hard part is not the math. The hard part is

execution.

A few tactics that help:

• Tie increases to raises. If your pay goes up, your contribution rate goes up.

• Use autopilot. Manual changes are where good intentions go to die.

• Keep it simple. A messy plan gets ignored.

FAQ

What is the 2026 403(b) contribution limit?

For 2026, the employee elective deferral limit for a 403(b) is $24,500.

What is the 2026 457(b) contribution limit?

For 2026, the elective deferral limit for a governmental 457(b) is $24,500.

Can I max both my 403(b) and 457(b) in 2026?

Often, yes. Because 403(b) and governmental 457(b) are separate plan types with separate elective deferral limits, many University employees who have access to both can contribute up to $24,500 to each (subject to your plan’s specific rules and eligibility).

What are the 2026 catch-up contributions for age 50+?

For 2026, the standard catch-up contribution for participants age 50+ in most 403(b) and governmental 457(b) plans is $8,000 (on top of the $24,500 limit).

What is the higher catch-up for ages 60–63 in 2026?

For 2026, ages 60–63 may be eligible for a higher “super catch-up” of $11,250 in these plans (instead of $8,000), depending on plan rules.

How should I prioritize 401(a), 403(b), and 457(b) contributions?

A simple Provizr-style prioritization that works well for most University employees is:

1. 401(a) first (because it’s usually tied to employer plan structure and employer

contributions; understand vesting and required rules)

2. 403(b) next as your core employee savings bucket (build a strong baseline here)

3. 457(b) after that if your University offers it (this is often the cleanest “save more”

lever)

4. Then optimize details like Roth vs pre-tax and fine-tune investments across TIAA Fidelity

If you’re trying to maximize total dollars across all sources (employee + employer), the IRS “annual additions” limit for defined contribution plans is $72,000 for 2026 (catch-up

contributions are generally on top of that).

Should I choose Roth or pre-tax for my University retirement plan?

It depends, but here’s the clean way to think about it:

• Pre-tax is often attractive if you want a tax break now and expect to be in a lower

bracket later.

• Roth is often attractive if you expect higher taxes later, want more tax

diversification, or value tax-free qualified withdrawals.

• Many University employees do best with a blend (some Roth, some pre-tax),

especially when they have multiple buckets (403(b) + 457(b)).

If you want the “right for you” answer, it usually requires looking at your current tax

picture, timeline, and how your TIAA/Fidelity accounts are set up.
