Are You Retirement Ready?

Can I Have Both a 403(b) and a 401(k)?

Yes, it's possible to have both a 403(b) and a 401(k) and contribute to both, typically if you hold multiple jobs or have transitioned between employers that offer different plans.

Having both allows you to potentially increase your pre-tax retirement contributions, diversify your investments, and maximize tax savings.

However, it also requires careful management. Each plan has its own rules, and there are also overall limits for all defined contribution plans to be aware of.

Therefore, it's crucial to balance your contributions, understand each plan's details, and consider how each fits into your overall financial goals.

You may also need to track the performance of investments across both accounts, which can be more complicated than managing a single account.

How Having Both a 403(b) and a 401(k) Works

Eligibility Criteria

To contribute to both a 403(b) and a 401(k), you need to be eligible for both types of plans. This usually means you're working in two different types of jobs—perhaps part-time in a non-profit (which offers a 403(b)) and part-time in a private-sector job (which offers a 401(k)).

Alternatively, you may have rolled over a 401(k) from a previous employer into a 403(b) with a current employer.

Contribution Limits and Rules

The IRS sets limits on how much you can contribute to these plans. For both 403(b) and 401(k) plans, the limit is $23,000 as of 2024.

However, if you're 50 or older, you can make catch-up contributions of an additional $7,500 per year. Importantly, these limits apply separately to each type of plan. That means if you have both plans, you can potentially double your pre-tax retirement contributions.

Investment Options

Both 403(b) and 401(k) plans offer a range of investment options, typically including mutual funds, index funds, and target-date funds. However, the specific choices available will depend on the plan provider and your employer's selections.

Tax Implications

Contributions to both 403(b) and 401(k) plans are made pre-tax, reducing your taxable income for the year.

The funds then grow tax-deferred until retirement, at which point withdrawals are taxed as ordinary income. The tax advantages of using both types of accounts can be significant, especially if you're in a high tax bracket now and expect to be in a lower one in retirement.

Benefits of Having Both a 403(b) and a 401(k)

Diversification of Investment Portfolios

Having both types of accounts can offer more opportunities for diversification, especially if the investment options in the plans are different. Diversification can help spread risk across different types of investments and potentially enhance returns over time.

Increased Contribution Limits

As mentioned, contributing to both a 403(b) and a 401(k) can effectively double your annual pre-tax retirement savings. This can be a huge advantage if you're trying to catch up on retirement savings or simply want to save as much as possible.

Potential for Greater Tax Savings

With the ability to contribute pre-tax dollars to both plans, you can significantly reduce your taxable income. This can be particularly beneficial if you're in a high tax bracket.

Different Loan Provisions

Some 403(b) and 401(k) plans offer loan provisions, allowing you to borrow from your account under certain conditions. If you have both types of plans, you may have more flexibility in terms of borrowing options.

Drawbacks of Having Both a 403(b) and a 401(k)

Complications in Managing Multiple Accounts

Having two retirement accounts can make management more complicated. You'll need to track contributions, monitor investments, and understand the different rules and restrictions for each plan.

Risk of Exceeding Aggregate Contribution Limits

While the contribution limits for 403(b) and 401(k) plans apply separately, there is a combined limit for all types of defined contribution plans. It's important to be aware of these overall limits to avoid potential tax penalties.

Different Rules and Regulations for Each Plan

Each type of plan has its own set of rules regarding contributions, withdrawals, loans, and other factors. Understanding and navigating these rules can be challenging, especially if you're managing both types of accounts.

Strategies for Balancing a 403(b) and a 401(k)

Assessing Personal Financial Goals

Before deciding how to allocate contributions between a 403(b) and a 401(k), consider your overall financial goals. Are you aiming for aggressive growth, or is income stability more important? The answer can guide your investment choices.

Understanding Employer Matching

If either or both of your employers offer matching contributions, try to contribute at least enough to get the full match—it's essentially free money.

Balancing Risk With Asset Allocation

Diversification is key in managing risk. Both your 403(b) and 401(k) should be part of a diversified portfolio that aligns with your risk tolerance and investment goals.

Keeping Track of Total Contributions

Remember that while the contribution limits for 403(b) and 401(k) plans are separate, there are overall limits for all defined contribution plans. Keep careful track of your contributions to avoid exceeding these limits.

Bottom Line

Having both a 403(b) and a 401(k) can significantly bolster your retirement savings strategy by providing avenues to maximize contributions, diversify investments, and optimize tax savings.

However, it also presents challenges such as increased complexity in management, the risk of exceeding total contribution limits, and understanding the distinct regulations of each plan.

Navigating these challenges involves keeping a keen eye on your overall financial goals, fully comprehending the specifics of employer match contributions, and maintaining a well-diversified portfolio that aligns with your risk tolerance.

Despite the complexities, the potential benefits can make managing both a 403(b) and a 401(k) a worthwhile strategy for those eligible.

Due to the intricate nature of these plans, seeking professional advice can be beneficial to ensure proper management of your retirement funds.
