Understanding Your 403(b) Plan: A University Employee's Guide

Executive Summary

Most University employees know they have a 403(b). Most do not realize their University splits it into two coordinated accounts: a Basic 403(b) and a 403(b) Supplemental Retirement Account (SRA). The two share a single combined 2026 elective deferral limit of $24,500. The most common 403(b) mistake University employees make is funding only the Basic 403(b) at the default 5% and never opening the SRA, leaving roughly $19,500 of tax-advantaged space unused every year. This guide explains how the 403(b) family works, the 2026 limits with all catch-up provisions, Roth vs. traditional, and the six recurring mistakes that cost retirement income.

Key Takeaways • A 403(b) plan is a tax-advantaged retirement account available to employees of public Universities, nonprofits, and other tax-exempt organizations. • The standard 2026 employee elective deferral limit is $24,500, with an additional $8,000 catch-up for employees aged 50 and older. • The SECURE 2.0 super catch-up lets employees aged 60 to 63 contribute an extra $11,250, for a potential total of $35,750 in 2026. • Most Universities split the 403(b) into two coordinated accounts: a Basic 403(b) (default-enrolled, often at 5% of salary) and a 403(b) SRA (voluntary additional contributions). They share the same combined elective deferral limit. • You can choose between traditional (pre-tax) and Roth (after-tax) contributions to either side of the 403(b) family. • Most University 403(b) plans offer investment options through TIAA, Fidelity, or both. • The 403(b) and the 457(b) have separate contribution limits, which means a University employee with access to both can defer up to $49,000 in voluntary employee contributions in 2026 (under age 50), $65,000 (age 50+), or $71,500 (ages 60 to 63).

The Hook: Two Accounts, One Limit

Open your TIAA or Fidelity portal and you might see something confusing. There are two 403(b) lines, not one. One says "403(b) Basic" or just "403(b)." The other says "403(b) SRA," "403(b) Voluntary," "Voluntary Tax-Deferred Account," or maybe "GSRA" (if you are at a TIAA-heavy school).

You did not enroll in two plans. Your University split your 403(b) into two coordinated accounts on purpose. The Basic 403(b) is usually default-enrolled at 5% of salary. The SRA is the voluntary "extra" account where additional employee contributions go after the basic election.

Here is the rule that catches most University employees by surprise: the IRS $24,500 elective deferral limit applies to the Basic 403(b) and the SRA combined, not to each separately. If you only contribute to the Basic 403(b) at the default 5%, you are leaving roughly $19,500 of tax-advantaged savings space unused in the SRA every year.

This article walks through how the 403(b) family works, the 2026 limits, the catch-up provisions, and the six recurring 403(b) mistakes University employees make.

What Is a University Employee 403(b) Plan?

A 403(b) plan is a tax-advantaged retirement savings account designed for employees of public schools, Universities, hospitals, and other tax-exempt organizations under Section 501(c)(3) of the Internal Revenue Code. The 403(b) plan lets employees defer a portion of their salary into an investment account, where the funds grow tax-deferred until withdrawal in retirement.

For University employees, the 403(b) is typically one of the primary retirement savings vehicles offered alongside a mandatory 401(a) defined contribution plan and (at public Universities) a 457(b) plan. Unlike a pension, a 403(b) gives you control over how much you contribute and how your money is invested.

How Does a 403(b) Differ From a 401(k)?

A 403(b) plan and a 401(k) plan serve the same fundamental purpose. Both let employees save for retirement with tax advantages. The difference is that they are authorized under different sections of the tax code for different types of employers. A 401(k) is available to employees of for-profit companies. A 403(b) is available to employees of nonprofit organizations, public schools, and Universities.

In practice, the differences that matter most to University employees are:

Feature	403(b)	401(k)
Eligible employers	Nonprofits, public schools, Universities	For-profit companies
2026 contribution limit	$24,500 (Basic + SRA combined)	$24,500
Catch-up (age 50+)	$8,000	$8,000
Super catch-up (ages 60 to 63)	$11,250	$11,250
15-year service rule	Available at some employers	Not available
Investment options	Annuities and mutual funds	Typically mutual funds only
Typical providers	TIAA, Fidelity	Varies widely

One notable difference is the 15-year service rule, unique to 403(b) plans. Employees with 15 or more years of service at the same qualifying employer may be eligible to contribute an additional $3,000 per year, up to a lifetime maximum of $15,000. Not all University plans adopt this provision, so check with your benefits office.

What Are the 2026 Contribution Limits?

The IRS sets annual contribution limits for 403(b) plans. For 2026, the limits are:

• Standard elective deferral limit: $24,500 for employees under age 50. (This applies to the 403(b) family combined: Basic + SRA.)

• Catch-up contribution (age 50 and older): an additional $8,000, bringing the total potential employee contribution to $32,500.

• SECURE 2.0 super catch-up (ages 60 to 63): an additional $11,250 instead of the standard $8,000 catch-up, bringing the total potential employee contribution to $35,750.

• Overall annual addition limit (Section 415(c)): $70,000, which includes both employee and employer contributions.

The SECURE 2.0 Act of 2022 created the super catch-up provision specifically to help employees in their early 60s accelerate their retirement savings during what is often their peak earning years. This provision applies only to participants who are aged 60, 61, 62, or 63 during the calendar year. Once a participant turns 64, the standard catch-up amount of $8,000 applies again.

Important 2026 rule for high earners: if you earned more than $150,000 in FICA wages in 2025, your catch-up contributions must be made on a Roth (after-tax) basis under SECURE 2.0. The rule applies only to the catch-up portion. Your standard $24,500 elective deferral can still be traditional pre-tax.

What Is the 403(b) Supplemental Retirement Account (SRA)?

Most Universities structure their 403(b) program as two coordinated accounts rather than one: a basic 403(b) and a 403(b) Supplemental Retirement Account (SRA). Some institutions label the SRA differently: Voluntary Tax-Deferred Account, 403(b) Voluntary, or Group Supplemental Retirement Annuity (GSRA) if structured as a TIAA annuity contract. The terminology varies. The structure does not.

The basic 403(b) is typically the default-enrollment account, often starting at 5% of salary. The 403(b) SRA is the voluntary "extra" account where additional employee contributions go beyond the basic election.

Critical rule: the IRS treats the basic 403(b) and the 403(b) SRA as a single combined elective deferral limit. The $24,500 cap is the total across both accounts, not the limit for each. A University employee whose basic 403(b) is auto-deducting 5% of a $100,000 salary ($5,000) would direct an additional $19,500 into the SRA to reach the $24,500 family limit.

The most common mistake University employees make is contributing only to the basic 403(b) at the auto-enrollment rate and never opening or funding the SRA. Over a 30-year career, that gap can leave six figures of tax-advantaged savings space unused.

To enroll in or fund your SRA, log into your TIAA or Fidelity portal and look for "Supplemental Retirement Account" or "403(b) Voluntary," or contact your University's benefits office.

Should You Choose Roth or Traditional 403(b) Contributions?

The choice between Roth and traditional 403(b) contributions depends primarily on whether you expect your tax rate to be higher now or in retirement.

Traditional 403(b) contributions are made with pre-tax dollars, which reduces your taxable income in the year of the contribution. Withdrawals in retirement are taxed as ordinary income. Roth 403(b) contributions are made with after-tax dollars. You pay taxes on the money now, but qualified withdrawals in retirement are completely tax-free.

Factor	Traditional 403(b)	Roth 403(b)
Tax benefit timing	Tax deduction now	Tax-free withdrawals later
Best if	Current tax rate is higher than expected retirement rate	Current tax rate is lower than expected retirement rate
Required Minimum Distributions	Yes, starting at age 73 (75 after 2033)	Can be rolled to Roth IRA to avoid RMDs
Contribution limits	Same $24,500 limit applies	Same $24,500 limit applies

Many financial professionals suggest that a mix of both traditional and Roth contributions can provide tax diversification in retirement, giving you flexibility to manage your tax bracket year by year.

What Investment Options Are Available in University 403(b) Plans?

Most University 403(b) plans offer investment options through TIAA, Fidelity, or both providers. TIAA has been the dominant retirement plan provider in higher education for nearly a century. Fidelity has become increasingly common as a secondary or primary option at many Universities.

TIAA typically offers its proprietary TIAA Traditional annuity, TIAA Real Estate Account, and a range of CREF variable annuity accounts, alongside a selection of mutual funds. Fidelity generally offers a lineup of index funds, target-date funds, and actively managed mutual funds.

The specific investment lineup varies by University because each institution negotiates its own plan contract. Some Universities offer dozens of investment options. Others have streamlined their menu to a curated set. An independent fiduciary advisor like Provizr can help you evaluate the specific options available in your plan.

What Are Common Mistakes University Employees Make With Their 403(b)?

Six recurring patterns across hundreds of University client reviews:

Mistake 1: Not opening or funding the 403(b) SRA. This is the single biggest 403(b) mistake. Contributing only to the Basic 403(b) at the default 5% leaves roughly $19,500 per year of tax-advantaged space unused. Over 30 years that gap compounds into hundreds of thousands of dollars in lost retirement income.

Mistake 2: Leaving accounts on default investment selections for decades. Many University employees enroll in their retirement plan, accept the default option, and never revisit. Over 20 or 30 years, this can mean being invested in an overly conservative option during peak earning and saving years.

Mistake 3: Overlooking catch-up contributions. Employees aged 50 and older are eligible for an additional $8,000 in 403(b) catch-up contributions. Employees aged 60 to 63 can contribute $11,250 under the SECURE 2.0 super catch-up. Both add up over five to fifteen years.

Mistake 4: Ignoring investment fees within the plan. University plans offer funds with different expense ratios. The difference between a fund charging 0.05% annually and one charging 0.50% annually may seem small. On a $500,000 balance, that difference is $2,250 per year, and over 15 years with compounding the fee drag can reduce a retirement balance by tens of thousands of dollars.

Mistake 5: Not coordinating accounts for tax efficiency. Holding tax-inefficient investments (bonds, REITs, high-turnover funds) in pre-tax accounts and tax-efficient investments (broad index funds) in Roth or taxable accounts can reduce your lifetime tax burden. Most University employees do not optimize which investments are held in which account type.

Mistake 6: Not reviewing beneficiary designations. Life changes such as marriage, divorce, or the death of a spouse may require updates to your beneficiary designations. Retirement account beneficiary designations typically override what is written in a will.

How Do University 403(b) Plans Work Day to Day?

When you enroll in your University's 403(b) plan, you select a contribution amount (either a dollar amount or a percentage of your salary) and choose how to allocate your contributions among the available investment options. Contributions are deducted from your paycheck each pay period and deposited into your account automatically.

You can typically change your contribution amount and investment selections at any time through your plan provider's website (TIAA.org or NetBenefits.Fidelity.com). Some changes, such as transfers out of TIAA Traditional, may be subject to restrictions depending on your University's contract.

Frequently Asked Questions

What is the difference between a 403(b) and a 403(b) SRA?

At most Universities, the 403(b) program is split into two coordinated accounts: a Basic 403(b) (default-enrolled at 5% of salary in most cases) and a 403(b) Supplemental Retirement Account (SRA), where employees can voluntarily direct additional contributions. The IRS $24,500 elective deferral limit applies to both accounts combined, not each separately.

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

$24,500 for employees under age 50 (this is the combined Basic 403(b) and 403(b) SRA limit). Employees aged 50 and older can contribute an additional $8,000 catch-up, for a total of $32,500. Employees aged 60 to 63 can contribute an additional $11,250 under the SECURE 2.0 super catch-up, for a total of $35,750.

Can I contribute to both a 403(b) and a 457(b) in the same year?

Yes. The 403(b) and 457(b) have completely separate elective deferral limits. A University employee can contribute the full $24,500 to the 403(b) family (Basic + SRA combined) and the full $24,500 to the 457(b) in 2026, for a combined total of $49,000 in employee contributions, before any employer 401(a) contributions on top.

Should I choose Roth or traditional 403(b) contributions?

Traditional 403(b) contributions reduce your current taxable income but get taxed at withdrawal. Roth 403(b) contributions are made with after-tax dollars and grow tax-free, with qualified withdrawals tax-free in retirement. Choose traditional if your current tax rate is higher than your expected retirement rate. Choose Roth if your current tax rate is lower. Many University employees use a mix of both for tax diversification.

Do my catch-up contributions have to be Roth in 2026?

Only if you earned more than $150,000 in FICA wages in 2025. Beginning in 2026, SECURE 2.0 requires high-earner catch-up contributions to employer-sponsored plans to be made on a Roth (after-tax) basis. The rule applies only to the catch-up portion. Your standard $24,500 elective deferral can still be traditional.

Next Steps

1. Log into your plan provider's website (TIAA.org or NetBenefits.Fidelity.com) and review your current contribution rate and investment allocations.

2. Check whether you are contributing to the SRA, not just the Basic 403(b). If you have only been funding the Basic at the default rate, opening the SRA is the highest-leverage move you can make today.

3. If you are 50 or older, confirm you are taking advantage of catch-up contributions. If you are between 60 and 63, look into the SECURE 2.0 super catch-up.

4. Review your beneficiary designations to make sure they reflect your current wishes.
