Retirement savings plans can feel overwhelming with so many choices available. Let’s clarify the distinction between 401(k) and 403(b) plans.

You might know you should have a 401(k), but understanding its purpose, benefits, and whether you should contribute can be tricky. Adding to the confusion, other options like 403(b) plans exist. If you start to think about Roth IRAs and traditional IRAs, it can become quite dizzying. Why do some employers offer one plan and not the other? What’s your responsibility? Should you rely solely on your employer's contributions, or should you invest your own money?

Don't stress. We’ll break down two major retirement plans: the 401(k) and the 403(b). The key difference is that 403(b) plans are available to employees of certain tax-exempt organizations like schools and hospitals, while 401(k) plans cater to those in for-profit companies.

Both options are excellent for retirement savings. Here’s a closer look at each.

401(k)

A 401(k) is a retirement plan sponsored by an employer, offering tax advantages and funded through payroll deductions.

Many employers will match a portion of your contributions.

You get to decide how much you want to contribute each pay period, with experts recommending you aim to contribute at least enough to get the full employer match since that’s essentially free money.

It's important to understand that your 401(k) is the account where you deposit your money, not your actual investments.

You’re in charge of selecting your investments, which can include company stock, ETFs, cash alternatives, and other options. Keep in mind that the available investment choices can vary by employer and plan administrator.

403(b)

A 403(b) is quite similar to a 401(k) but typically consists of annuity contracts or custodial accounts for mutual funds. Its name also comes from the tax code that regulates it, and it’s often referred to as a “tax-sheltered annuity” (TSA).

Like 401(k)s, contributions to 403(b)s are tax-deductible, and employers may offer matching contributions as well. Additionally, you can take out loans against either type of account, although some experts caution against this.

Similarities Between 401(k) and 403(b)

Both plans share several common features. First, they have the same contribution limits. If you’re under 50, the max contribution is $23,500. If you’re over 50, you can make a catch-up contribution of $7,500, bringing the total to $31,000 each year.

Both plans also require you to be at least 59 ½ years old to withdraw funds. Additionally, if your employer offers it, both plans may include Roth options.

“Both plans offer employees a chance to invest in their future through tax-deductible and tax-deferred investment vehicles, aiming to enhance retirement income,” says a certified financial planner.

However, she notes that drawbacks are similar for each.

“The government incentivizes investing and growth through tax benefits, but early withdrawals before 59 ½ can incur hefty penalties. While some exceptions exist, a 10% penalty is significant, and ordinary income tax applies to any withdrawals,” she adds.

Which is Superior?

So, which plan is better? Both are solid choices for retirement savings.

“I consider them both beneficial! Typically, 401(k) plans offered by more profitable companies provide matching contributions, a great advantage that many non-profits might lack,” she explains. “Furthermore, an increasing number of for-profit employers are adding Roth 401(k) options, providing even more planning avenues, although 403(b) Roth plans are also available. Additionally, both plans allow loans up to 50% of the plan value, which can be useful for things like home purchases or education expenses,” she continues.

However, be sure to check with your plan administrator to understand what features you can utilize in your specific plan.

Take Action

When it comes to retirement savings, the most crucial step is to start, she adds.

“Most people find that if money is available at home, it tends to get spent! The convenience of employer-sponsored plans funded through payroll deductions is invaluable,” she emphasizes.

Of course, there are various other methods to save for retirement.

“You can also consider funding IRAs and Roth IRAs, as these are self-directed and require discipline to invest wisely… And don’t shy away from establishing a tax-efficient portfolio outside of qualified plans,” she suggests.
