What Is a 403(b) Plan?

The term 403(b) plan refers to a retirement account designed for certain employees of public schools and other tax-exempt organizations. Participants may include teachers, school administrators, professors, government employees, nurses, doctors, and librarians.

The 403(b) plan, which is closely related to the better-known 401(k) plan, allows participants to save money for retirement through payroll deductions while enjoying certain tax benefits. There’s also an option for the employer to match part of the employee’s contribution.

How 403(b) Plans Work

As noted above, individuals employed by schools and other tax-exempt organizations can save for retirement by contributing to a 403(b) plan through payroll deductions. The plan is akin to the 401(k) plan used by private-sector employees. Participants can include:

• Employees of public schools, state colleges, and universities
• Public school employees of Indian tribal governments
• Church employees
• Employees of tax-exempt 501(c)(3) organizations
• Ministers and clergy members

The 403(b) plan has the same caps on yearly contributions that come with 401(k) plans. The maximum contributions allowed are $20,500 and $22,500 for the 2022 and 2023 tax years respectively. For 2022, he plan also offers $6,500 catch-up contributions for those age 50 and older, increasing to $7,500 for 2023. Combined employee and employer contributions are limited to the lesser of $61,000 in 2022 and $66,000 in 2023 or 100% of the employee’s most recent yearly salary.

Participants must reach age 59½ before withdrawing funds or get slapped with an early withdrawal penalty. 

Special Considerations

Although it is not very common, your job situation could end up giving you access to both a 401(k) and a 403(b) plan. Each offers employees a tax-advantaged way to save for retirement, but investment choices are often more limited in a 403(b) plan than a 401(k). And remember, 401(k)s serve private-sector employees.

But unlike a 401(k), the 403(b) plan also offers a special plan for those with 15 or more years of service with the same employer (see below).

Types of 403(b) Plans

There are generally two broad types of 403(b) plan—the traditional and the Roth. Not all employers allow employees access to the Roth version.

A traditional 403(b) plan allows the employee to have pretax money automatically deducted from each paycheck and paid into a personal retirement account. The employee has put away some money for the future and at the same time reduced his or her gross income (and income taxes owed for the year). The taxes will be due on that money only when the employee withdraws it.

A Roth 403(b) requires that after-tax money be paid into the retirement account. There’s no immediate tax advantage. But the employee will not owe any more taxes on that money or the profit it accrues when it is withdrawn.

Advantages and Disadvantages of 403(b) Plans

There are distinct benefits and drawbacks of holding a 403(b) plan. We’ve highlighted some of the most common ones below.

Advantages

Earnings and returns on amounts in a regular 403(b) plan are tax-deferred until they are withdrawn. Earnings and returns on amounts in a Roth 403(b) are tax-deferred if the withdrawals are qualified distributions.

Certain 403(b) plans are not required to meet the onerous oversight rules of the Employee Retirement Income Security Act (ERISA). As such, these plans tend to come with lower administrative costs, which puts more money back into the employee’s pocket.

Many 403(b) plans vest funds over a shorter period than 401(k)s, and some even allow immediate vesting of funds, which 401(k)s rarely do.

If an employee has 15 or more years of service with certain nonprofits or government agencies, they may be able to make additional catch-up contributions to a 403(b) plan. Under this provision, you can contribute an additional $3,000 a year, up to a lifetime limit of $15,000. And unlike the usual retirement plan catch-up provisions, you don’t have to be 50 or older to take advantage of this as long as you worked for the same eligible employer for the whole 15 years.

Disadvantages

Funds withdrawn from a 403(b) plan before age 59½ are subject to a 10% tax penalty, although you may avoid the penalty under certain circumstances, such as separating from an employer at age 55 or older, needing to pay a qualified medical expense, or becoming disabled.

A 403(b) may offer a narrower choice of investments than other plans. Although these plans now offer mutual fund options inside variable annuity contracts. you can only choose between fixed and variable contracts, and mutual funds inside these plans⁠—other securities, such as stocks and real estate investment trusts (REITs), are prohibited.

The presence of an investment option that 403(b)s favor is, at best, a mixed blessing. When the 403(b) was invented in 1958, it was known as a tax-sheltered annuity. While times have changed, and 403(b) plans can now offer mutual funds, as noted, many still emphasize annuities.

Financial advisors often recommend against investing in annuities within a 403(b) and other tax-deferred investment plans. Accounts may lack the same level of protection from creditors as plans that require ERISA compliance. If you are at risk of creditors pursuing you, speak to a local attorney who understands the nuances of your state as the laws can be complex.

Another disadvantage of non-ERISA 403(b)s is their exemption from nondiscrimination testing. Done annually, this testing is designed to prevent management-level or highly compensated employees from receiving a disproportionate amount of benefits from a given plan.
