Already Maxed Out Your Roth IRA, 401(k), and HSA? Here’s What to Do Next

You’ve paid off your debt, maxed out your retirement accounts, and set up your emergency fund. Now what?

That’s the exact position Kelley finds herself in. She’s wondering how to optimize her next investment steps to reach Financial Independence (FI) faster.

Kelley is doing an exceptional job already, but her question reflects a common next-step challenge for many on the FI path. Let’s explore how she—and others in a similar position—can optimize investments, reduce taxes, and maintain flexibility along the journey to FI.

Understanding Kelley’s Financial Foundation

Before jumping into advanced tactics, let’s recognize how strong Kelley’s financial starting point is:

• ✅ No debt (except mortgage)
• ✅ Fully funded emergency fund
• ✅ Maxed out HSA
• ✅ Maxed out Roth 401(k)
• ✅ Backdoor Roth IRA contributions

This means Kelley is already contributing nearly $35,000/year to tax-advantaged accounts (even before employer matches)—a huge win.

What’s Next? The Retirement Savings Order of Operations

Once the foundational steps are complete, here’s the typical FI-friendly order of operations to guide next moves:

Kelley’s already completed steps 1–4, and now it’s time to consider Steps 5 and 6.

Why a Taxable Brokerage Account Might Be Kelley’s Next Best Move

“Is the best strategy to put that in a normal mutual fund / stock market?”

Yes—and that typically means opening a taxable brokerage account, which offers:

✅ Key Benefits:

• No income, age, or contribution limits
• Favorable tax treatment for qualified dividends and long-term capital gains
• Maximum flexibility with no early withdrawal penalties
• Low-cost index funds and ETFs at brokers like Vanguard and Fidelity

“Once you contribute cash to the taxable brokerage account, you can invest in anything you want... including low-cost stock market index funds.”

Before jumping in, Kelley should assign each dollar an anticipated “job” and use-by date, which helps align investments with timing and risk tolerance.

🗂 Example: Matching Investments to Time Horizon

Should Kelley Switch from Roth to Traditional 401(k)?

“It sounds like you might be in your highest earning years... probably in the 22% and higher tax brackets.”

If that’s the case, Kelley may benefit from switching her contributions to a Traditional 401(k) instead of Roth:

🔄 Roth vs. Traditional 401(k)

Reducing taxable income with traditional contributions today could free up more money to invest in her taxable brokerage account.

🚪 The Mega Backdoor Roth: Hidden Superpower?

“Your 401(k) plan... may also allow you to contribute beyond that with what’s called after-tax contributions.”

If Kelley’s employer plan allows it, she might unlock the Mega Backdoor Roth—an advanced strategy that allows after-tax 401(k) contributions and in-service conversions to Roth accounts.

How It Works:

1. Contribute after-tax dollars to your 401(k)

2. Convert those to Roth via:

   • In-service withdrawal to Roth IRA
   • In-plan Roth conversion to Roth 401(k)

This can potentially allow over $60,000 in total annual contributions (depending on the IRS limit for the year and employer match).

🔍 To explore this option: Request the Summary Plan Description (SPD) from HR and look for terms like “after-tax contributions,” “in-service distribution,” or “Roth conversion.”

Risk Management: Don’t Skip the Essentials

“Make sure you haven't overlooked any risk management basics...”

As Kelley accelerates toward FI, protecting what she’s building is just as important as growing it.

✅ Risk Management Checklist:

• ✅ Long-term disability insurance
• ✅ Appropriate life insurance
• ✅ Sufficient homeowners, auto, and umbrella coverage
• ✅ Estate documents (will, powers of attorney, healthcare directive)

Boosting Income and Aligning with Your Values

“I wonder if you have already explored ways to increase your income...”

To further speed up her FI timeline—or create room for more giving, leisure, or impact—Kelley might consider:

• Negotiating a raise at work
• Exploring higher-paying roles
• Side hustles (freelance, consulting, real estate)
• House hacking or low-cost living strategies
• Shifting spending to align with values (it’s not all about cutting costs)

“You might be able to actually increase your current spending and giving, assuming those decisions are aligned with your unique values.”

Kelley’s Strategy Recap

Let’s bring it all together in a simplified strategy table:

Final Thoughts: It’s Not All or Nothing

“You’re clearly doing a fantastic job in asking the right questions, Kelley...”

Kelley is already in the top tier of financial preparedness. At this point, she’s not choosing between “right” and “wrong” strategies—she’s optimizing among good options.

The path to FI doesn’t have to be all-or-nothing. It’s okay to mix Roth and Traditional, invest in both taxable and retirement accounts, and pursue growth while protecting what you’ve built.
