If you’ve ever wondered whether you can roll your old 401(k) into your LLC—perhaps to invest in real estate, crypto, or private lending—you’re not alone. This is one of the most common questions we get from self-employed individuals each week.
Watch: Learn about how you can invest through a solo 401k or a solo 401k funded LLC
The short answer: You can’t roll your 401(k) directly into an LLC, but you can use a Solo 401(k) to legally invest through an LLC structure. Here’s how it works—and how to do it the right way.
Why People Ask About Rolling a 401(k) Into an LLC
Many investors want more control over their retirement funds and prefer tangible assets like real estate, private equity, or cryptocurrency instead of traditional Wall Street investments.
A Solo 401(k) offers this flexibility. Once established, it can invest directly in these asset classes—or through a properly structured LLC owned by the plan. However, compliance is key. The IRS has strict rules to prevent self-dealing and prohibited transactions.
The Right Way: Solo 401(k) → LLC Investment
You cannot transfer funds from a former employer’s 401(k) or IRA directly into an LLC. Doing so would trigger a taxable distribution—a mistake that could lead to taxes and penalties.
Instead, the correct sequence is:
-
Establish a Solo 401(k) for your self-employed business (no full-time W-2 employees other than a spouse).
-
Roll over your former employer 401(k) or IRA into the Solo 401(k) plan.
-
Create a new single-member LLC (the Solo 401(k) must be its sole member).
-
Open a bank account for the LLC using its own EIN (not the Solo 401(k)’s EIN).
-
Fund the LLC by wiring money from the Solo 401(k) trust bank account.
-
Use the LLC to make passive investments such as:
-
Real estate purchases
-
Promissory notes
-
Private lending
-
Crypto or private equity deals
-
Remember: The LLC must be newly formed for investment purposes—not an existing business you operate.
The Wrong Way: Direct Transfer to an LLC
If you transfer funds directly from an IRA or old 401(k) into an LLC’s bank account, the IRS will treat that as a distribution—immediately taxable and potentially subject to penalties. Always ensure funds are first transferred into a qualified plan (your Solo 401(k)) before being invested through an LLC.
Prohibited Transactions to Avoid
Even when structured correctly, your LLC must still follow all Solo 401(k) prohibited transaction rules. That means:
-
You cannot invest in property or businesses you or disqualified persons (spouse, parents, children) personally own.
-
You cannot use plan funds for personal benefit.
-
You cannot perform “sweat equity” work (like repairs or construction) on LLC-owned properties.
-
You cannot receive commissions, compensation, or fees from plan investments.
The goal is to keep all investments arm’s length and exclusively for retirement benefit—not personal gain.
Common Scenario: Real Estate Investing Through an LLC
Let’s say your Solo 401(k) invests in an LLC that buys rental property.
-
The LLC is on the property title, not your name or the Solo 401(k) directly.
-
Rental income is deposited into the LLC’s bank account.
-
Expenses (like property taxes) are paid from the LLC account.
-
You may act as your own broker only if you receive no commission or compensation.
If your plan includes both Roth and pre-tax Solo 401(k) funds, you can invest both through the same LLC, allocating ownership proportionally.
Can I Use My Solo 401(k) LLC to Fund My Own Business?
No. That’s a prohibited transaction.
The Solo 401(k) LLC is for passive investments only, not for funding or operating your own business.
If you want access to capital for personal or business use, the compliant option is a Solo 401(k) participant loan—you can borrow up to 50% of your account balance, up to $50,000, and repay it with interest over five years.
Key Takeaways
✅ You can’t roll your 401(k) directly into an LLC.
✅ You can roll it into a Solo 401(k), then have that plan invest in a new, single-member LLC.
✅ The LLC must be structured and operated correctly to stay IRS-compliant.
✅ All transactions must remain arm’s length—no personal benefit.
✅ Real estate, private lending, and crypto are all permissible passive investments.
Final Thoughts
With the right setup, a Solo 401(k) gives you checkbook control and the freedom to invest in what you know—without giving up IRS protection or tax benefits. But structure matters. Done the wrong way, you could trigger taxes or disqualify your plan.
