403(b) Plan: What It Is and Why It Matters

Definition

A 403(b) plan is a tax-advantaged retirement savings plan available to employees of public schools, certain non-profit organizations, and some members of the clergy. It functions similarly to a 401(k) plan, allowing employees to contribute a portion of their salary to an individual account, where it can grow tax-deferred until retirement.

How It Works

Employees of eligible organizations can contribute to a 403(b) plan through automatic payroll deductions. These contributions can be made on a pre-tax basis, which lowers your current taxable income, or as Roth contributions, which are made with after-tax dollars but allow for tax-free withdrawals in retirement. The money in a 403(b) plan is invested in a portfolio of mutual funds and/or annuities, with the potential for growth over time. Some employers may also choose to contribute to their employees' 403(b) accounts, though this is less common than with 401(k) plans.

Key Rules and Limits

• Contribution Limits: For 2026, the maximum amount an employee can contribute to a 403(b) plan is $24,500.
• Age 50+ Catch-Up Contributions: If you are age 50 or older, you can contribute an additional $8,000 in 2026, for a total of $32,500.
• Ages 60-63 "Super" Catch-Up: A provision in the SECURE 2.0 Act allows for a higher catch-up contribution for those aged 60, 61, 62, and 63. For 2026, this additional amount is $11,250, allowing for a total contribution of $35,750, if the plan allows.
• 15-Year Service Catch-Up: Some 403(b) plans offer a special catch-up for employees with 15 or more years of service with the same employer. This allows for an additional contribution of up to $3,000 per year, with a lifetime maximum of $15,000.
• Roth Catch-Up for High Earners: Beginning in 2026, if your FICA wages from the previous year were $150,000 or more, any catch-up contributions must be made on a Roth (after-tax) basis.
• Total Contribution Limit: The combined total of employee and employer contributions cannot exceed $72,000 in 2026.
• Withdrawal Rules: You can typically begin taking penalty-free withdrawals at age 59 ½. Withdrawals before this age may be subject to a 10% early withdrawal penalty, in addition to regular income tax. Exceptions to the penalty may apply for disability, separation from service after age 55, and other specific circumstances.
• Required Minimum Distributions (RMDs): You generally must start taking RMDs from your traditional 403(b) account at age 73.

Example

Sarah is a 45-year-old teacher who earns $60,000 a year. She contributes 10% of her salary to her school's 403(b) plan, which is $6,000 per year. Her contributions are pre-tax, so her taxable income is reduced to $54,000. Assuming an average annual return of 7%, her 403(b) account could grow to over $560,000 by the time she retires at age 65.

Pros and Cons

Pros:

• Tax Advantages: Contributions can be made pre-tax, lowering your current taxable income, or as Roth contributions for tax-free withdrawals in retirement.
• Tax-Deferred Growth: Your investments grow without being taxed annually.
• High Contribution Limits: The annual contribution limits are significantly higher than those for IRAs.
• Potential for Employer Contributions: Some employers may offer matching contributions.
• Unique Catch-Up Provisions: The 15-year service catch-up is a unique feature not available in 401(k) plans.

Cons:

• Limited Investment Options: 403(b) plans historically have had more limited investment choices, often focused on annuities and mutual funds, compared to 401(k)s.
• Potentially Higher Fees: Some 403(b) plans, particularly those with annuity products, can have higher fees than 401(k)s.
• Less Common Employer Match: Employer matching contributions are not as common in 403(b) plans as they are in 401(k)s.

Common Mistakes to Avoid

• Not Starting Early: The longer your money has to grow, the more you'll have in retirement. Delaying contributions means missing out on the power of compounding.
• Choosing High-Fee Investments: High fees can significantly erode your investment returns over time. Pay close attention to the expense ratios of the funds you choose.
• Being Too Conservative: While it's important to consider your risk tolerance, being overly conservative with your investments, especially when you're young, can limit your potential for growth.
• Not Diversifying: Spreading your investments across different asset classes can help to reduce risk.
• Ignoring Your Account: It's important to review your 403(b) plan at least once a year to ensure your investment strategy is still aligned with your goals.
• Taking Early Withdrawals: Withdrawing money from your 403(b) before retirement can result in significant taxes and penalties, and you'll lose out on future tax-deferred growth.

Frequently Asked Questions

Q: Can I contribute to a 403(b) and a 401(k) at the same time?

A: Yes, you can contribute to both a 403(b) and a 401(k) if you have jobs that offer each type of plan. However, the total amount you can contribute to both plans combined cannot exceed the annual employee contribution limit ($24,500 in 2026).

Q: What's the difference between a 403(b) and a 457(b) plan?

A: Both are retirement plans for public sector and non-profit employees. The main difference is that contributions to a 457(b) plan are not aggregated with 401(k) or 403(b) contributions. This means you could potentially contribute the maximum to both a 403(b) and a 457(b) plan in the same year.

Q: What happens to my 403(b) if I leave my job?

A: You have several options. You can typically leave the money in the plan, roll it over to an IRA, or roll it over to your new employer's retirement plan if they accept rollovers. You also have the option of cashing out, but this is generally not recommended due to taxes and penalties.
