Workplace Retirement Plans

Are You Limited to the Funds in Your 401(k)?
Many workplace retirement plans include an option most participants have never heard of: the self-directed brokerage account, or SDBA. This page explains what an SDBA is, how to find out whether your plan offers one, and how to think clearly about whether it fits your situation.
Have a 403(b) or 457(b) instead — common at hospitals, schools, and nonprofits? Everything here applies to you, too.

What Is a Self-Directed Brokerage Account?
A self-directed brokerage account — sometimes called a “brokerage window” — is a feature that some employer-sponsored retirement plans — including 401(k), 403(b), and 457(b) plans — offer alongside the plan’s core investment menu. Where available, it allows a participant to direct a portion of their retirement savings into a broader range of investment choices, while the money remains inside the workplace plan.

Your money stays in the plan
An SDBA is not a rollover, a withdrawal, or a distribution. Your savings remain inside your employer’s retirement plan.
Availability varies
Not every plan offers a brokerage window, and plans that do set their own rules, limits, and eligible investments.
More choice, more responsibility
A wider investment menu can be a meaningful benefit — or an added burden — depending on your goals, experience, and time.
Costs can differ
SDBAs may involve additional account fees or trading costs. Understanding them is part of any honest evaluation.
Could This Apply to Me?
There’s no universal answer here — and it’s worth being cautious of anyone who suggests otherwise. This is an honest starting point.
An SDBA may be worth exploring if…
✓ Your plan offers one, and the core investment menu feels limiting.
✓ Your workplace plan is one of your largest accounts, and you want it coordinated with the rest of your financial life.
✓ You would value professional guidance on an account that often receives none.
✓ You are a longer-tenured employee or executive with a significant plan balance.
An SDBA may not be a fit if…
– Your plan doesn’t offer one — many don’t.
– The plan’s core menu already serves your needs well.
– Additional costs would outweigh any benefit for your balance or situation.
– You value simplicity more than additional choice.
That’s exactly what a first conversation is for: an honest look at your plan and your situation — including a plain answer if an SDBA isn’t right for you.

Frequently Asked Questions
What is a self-directed brokerage account?
It’s an optional feature some employer retirement plans offer that lets a participant invest a portion of their plan savings beyond the plan’s standard investment menu, while the money stays inside the plan.
I have a 403(b), not a 401(k). Does this apply to me?
Often, yes. Brokerage windows exist in many plan types — 401(k), 403(b), and 457(b) plans among them. If you work for a hospital system, school district, or nonprofit, your plan may offer one. As with any plan, the only way to know is to check your specific plan’s features.
How do I find out whether my plan offers one?
Check your plan’s summary plan description, log in to your plan provider’s website, or ask your HR or benefits department. If you’d rather not dig through documents, bring a recent statement to an introductory call and we can look together.
What can I invest in through an SDBA?
It depends on your plan. Brokerage windows often provide access to a broader range of mutual funds and exchange-traded funds, and some plans permit individual securities. Each plan sets its own rules on what is and isn’t allowed.
Does my money leave my 401(k)?
No. An SDBA operates inside your workplace retirement plan. It is not a rollover or a distribution, and using one does not by itself change the tax treatment of your retirement savings.
Are there additional costs?
There can be. Depending on the plan and provider, an SDBA may involve account fees, trading costs, or — if you engage an advisor — an advisory fee. Any evaluation of an SDBA should include a clear-eyed look at total costs.
Can a financial advisor help me manage an SDBA?
In many plans, yes — participants may be able to authorize a financial professional to provide advice on, or manage, the brokerage window portion of their account. Whether and how this works depends on your plan and its provider, which is one of the first things we would confirm.
Is an SDBA right for everyone?
No. For many participants, the plan’s core menu is the better fit — simpler, and often lower cost. An SDBA deserves consideration only when the added choice serves a real purpose in your broader financial picture.
What happens on the introductory call?
It’s a 15-minute phone call. You bring your questions — and a recent statement if you have one handy. We can usually determine whether your plan offers a brokerage window and whether it’s worth a closer look. There’s no cost and no obligation.
