A 403(b) plan remains a tax‐advantaged retirement vehicle designed for employees of tax‐exempt organizations—including public schools, higher education institutions, churches, and charities. While the basic concept is unchanged, 2025 brings several important updates that affect contribution limits, catch‐up rules, and even plan design for long‐term, part‐time employees. In this article, we review the latest news, regulatory updates, and practical considerations to help you or your organization stay informed and optimize your retirement savings strategy.
Updated Contribution Limits for 2025
One of the most notable changes for 2025 is the increase in contribution limits. According to recent IRS announcements and industry reports, the employee elective deferral limit for 403(b) plans is now $23,500—up from $23,000 in 2024—and the combined limit (employer plus employee contributions) has increased to $70,000 from $69,000. These adjustments help account for inflation and give participants more room to save for retirement
Enhanced Catch-Up Provisions for Older Workers
The changes in the 2025 contribution limits also come with updated catch-up rules. While employees aged 50 and older have long been eligible for an additional $7,500 catch-up contribution, a significant update now applies to those between ages 60 and 63. Under the new guidelines—which stem from provisions in the SECURE 2.0 Act—these workers may contribute up to $11,250 as catch-up, effectively boosting their potential annual contributions to as much as $34,750 when combined with the regular deferral. This “super catch-up” opportunity is intended to help those in the later stages of their careers accelerate their savings
403(b) as a Supplemental Retirement Plan and New SECURE 2.0 Features
For many employees, a 403(b) serves as a supplemental retirement account alongside other savings vehicles such as 401(k)s or IRAs. Many plan sponsors now offer enhanced options—including automatic enrollment and improved in‐plan distribution choices—under the evolving SECURE 2.0 framework. Newer 403(b) plans may incorporate features such as:
- Automatic Enrollment: New plans (and in some cases, existing ones that amend their documents) are required to automatically enroll eligible employees at a modest rate, with contributions set to increase gradually over time. This measure is designed to boost participation rates without forcing contributions upon employees quarles.com.
- Flexible In-Service Distributions: While the traditional penalty‐free withdrawal age remains at 59½ (with some special provisions allowing access at 55 for certain retirement scenarios), plan sponsors are increasingly offering options for hardship or emergency withdrawals, albeit with careful attention to tax consequences.
These enhancements not only promote increased retirement savings but also offer more flexibility for participants when accessing their funds during times of financial need.
New Long-Term, Part-Time (LTPT) Employee Guidelines
A key regulatory update effective January 1, 2025, concerns long-term, part-time employees. Under new IRS guidance issued in late 2024, 403(b) plans that are subject to ERISA must now allow any part-time employee who works at least 500 hours in each of two consecutive 12-month periods to make elective deferrals—even if they normally work less than 20 hours per week. This update—part of broader changes introduced under SECURE 2.0—aims to expand access to retirement savings for employees who might otherwise be excluded from participation.

Importantly, while these LTPT employees must be allowed to make salary deferrals, employers are not required to extend matching or non-elective contributions to them unless the employee later meets the plan’s standard eligibility criteria (for example, accumulating 1,000 hours of service in a 12-month period). Employers and plan administrators are advised to review and, if needed, amend plan documents to ensure compliance with these new rules.
Types of 403(b) Plans: Choosing the Right Option
403(b) plans generally come in several variations:
- Tax-Deferred Annuity (TDA) 403(b) Plans: Often referred to as 403(b) annuity plans, these accounts allow contributions to grow tax-deferred until withdrawals begin. Distributions are then taxed according to your ordinary income tax rate at retirement.
- Roth 403(b) Plans: In contrast, contributions to a Roth 403(b) are made with after-tax dollars. Qualified withdrawals—including earnings—are tax-free, making this an attractive option if you expect to be in a higher tax bracket in retirement.
- Specialized 403(b) Plans for Churches and Related Organizations: These plans, sometimes denoted as 403(b)9 or 403(b)7 (the latter typically investing in mutual funds), are tailored to meet the unique needs of church employees and affiliated organizations.
Each option offers different advantages regarding taxation, investment choices, and withdrawal strategies. It is essential to review your individual circumstances and possibly consult with a financial advisor to determine which plan type aligns best with your long-term goals.
How Does a 403(b) Plan Work?
At its core, a 403(b) plan is a defined-contribution retirement account that allows participants to contribute a portion of their salary on a pre-tax (or post-tax, in the case of Roth) basis. The funds are then invested—typically in annuities, mutual funds, or other approved vehicles—with the earnings growing tax-deferred until withdrawal. Upon retirement, distributions are subject to income tax (for traditional contributions) or may be tax-free (for Roth contributions), depending on the nature of the contributions.
Fiduciaries and plan administrators are responsible for ensuring that the investments are managed prudently and in accordance with IRS regulations, which are periodically updated to reflect changing economic conditions and legislative priorities.
Weighing the Pros and Cons of a 403(b)
Pros
- Tax Advantages: Contributions are either pre-tax (reducing your current taxable income) or made with after-tax dollars in a Roth account, with the potential for tax-free growth.
- Higher Contribution Limits: With increased limits for 2025 and additional catch-up provisions, especially for employees aged 60-63, 403(b) plans offer substantial savings potential.
- Employer Matching Contributions: Many employers offer matching contributions, which can significantly boost your overall retirement savings.
- Supplemental Retirement Savings: For employees who already have a 401(k) or other retirement account, a 403(b) can serve as an important additional savings tool.
- Flexible Investment Options: Although many 403(b) plans traditionally relied on annuity contracts, modern offerings increasingly include a range of mutual funds and other investment vehicles.
Cons
- Withdrawal Restrictions and Penalties: Early withdrawals (typically before age 59½) may incur a 10% penalty along with income tax.
- Potentially Higher Fees: Some 403(b) plans—especially those that are annuity-based—may charge higher fees compared to other retirement plans, which can erode long-term returns.
- Complex Rules: Navigating the rules—especially in light of new LTPT requirements and periodic limit adjustments—can be challenging. It is advisable to stay updated on regulatory changes and consult with professionals as needed.
- Investment Limitations: Depending on the plan provider, investment options may be more limited than those available in other types of retirement accounts.
Conclusion
A 403(b) plan remains a valuable retirement savings tool for employees of tax-exempt organizations. With the 2025 updates—including higher contribution limits, enhanced catch-up rules for older workers, and expanded access for long-term, part-time employees—participants now have even greater opportunities to build a robust retirement nest egg. However, the complexity of the rules and potential fees means that regular reviews of your plan options and consultation with a financial advisor are essential.
As regulatory updates from the IRS and changes under the SECURE 2.0 Act continue to evolve, staying informed and proactive about your retirement strategy will help ensure that your savings keep pace with your future needs.
