When it comes to examining all of the account options available for retirement, 401(k) plans tend to get the most attention. But if you work at a school, hospital, library, research facility, church, or another organization qualified under IRS Section 501(c)(3), you probably know about 403(b) plans. A 403(b), sometimes referred to as a tax-sheltered annuity plan or TSA, is a retirement plan for employees of public schools and certain non-profit organizations.

403(b) Contribution Limits for 2018

These amounts may change from year to year but will remain the same as the 2017 contribution limits. For 2018, the maximum amount you can contribute to a 403(b) plan is $18,000 ($24,000 if age 50 or older) or 100% of compensation.

In addition to the employee contribution limits, more money can be added to a 403(b) if an employer offers match contributions. For plans that provide an employer match, the total contribution limit is $54,000. The employee contribution limit remains the same as above, but the employer may choose to add up to another $36,000 (not to exceed the maximum of $54,000 in 2018).

Main Benefits of Contributing to a 403(b)

403(b) plans used to be primarily invested in annuity contracts, with a separate account for fixed or variable rate of return investments. Now the majority of 403(b) plans offer mutual fund investment options within custodial accounts. While some 403(b) plans still offer annuity investments, the use of a diversified investment lineup of mutual funds is very similar to the structure of traditional 401(k) plans.

The most common benefit of 403(b) plans lies in the fact that contributions are made through pre-tax salary deferrals. If you work for a company that offers a 403(b), by participating in your employer’s plan, you can help strengthen your retirement in the following ways:

  • Automatically build wealth for retirement.
  • Lower your taxable income through pre-tax contributions.
  • Take advantage of dollar cost averaging by investing each pay period.
  • Generate earnings that will grow tax-deferred and won't be taxed until you withdraw them.
  • Benefit from possible employer matching contributions.

2018 Limits for Roth 403(b)s

The designated Roth account (DRA) program allows organizations to designate 403(b) plan contributions as Roth contributions. Roth 403(b) plans are very similar to Roth 401(k)s. This option is relatively new. The primary benefit is that you can make after-tax contributions that allow for tax-free growth of your investments.

For 2018, the annual contribution limit for Roth 403(b)s is $18,000, plus an additional $6,000 catch-up contribution for those age 50 or older.

  • Contributions are made with after-tax dollars (no current-year tax deduction).
  • Earnings grow tax-free as long as you are at least 59 ½ years old, and it has been five years since your first Roth 403(b) contribution.
  • Unlike Roth IRAs, there are no income restrictions.
  • Provides tax diversification
  • Eligible for a rollover to a Roth IRA at retirement to avoid required minimum distributions (RMD)

If your plan offers a Roth 403(b) option. you may contribute to a traditional, pre-tax 403(b) and a Roth 403(b) in the same year as long as the combined contribution amount does not exceed the annual limit.

Differences Between a 403(b) and a 401(k)

Today 403(b) plans are very similar to 401(k) plans. But this wasn’t always the case. The Economic Growth and Tax Relief Reconciliation Act of 2001 eliminated previous differences between these different types of retirement plans.

But one special election—referred to as the 15-year rule—is still in effect for 403(b) plans (if permitted by the employer). This special lifetime catch-up provision allows employees with 15 or more years of service with the same employer to contribute an additional $3,000 if the average contributions in previous years didn't exceed $5,000. Under current rules, this catch-up provision can't exceed $3,000 per year, up to a lifetime maximum of $15,000. If both the age 50 and the 15-year catch-up provisions are available, any contributions that exceed the $18,000 annual limit will first be applied using the 15-year rule, followed by the age 50 catch-up.
