Multi-Member IRA LLCs are possible, but they’re only really viable in a very narrow set of circumstances. While it seems like an attractive option — one LLC instead of two — the restrictions on it are so prohibitive that most of our clients who express an interest in it find that it actually doesn’t suit their needs.

To understand why, we have to go back a few years and look at the legal case that helped establish the IRA LLC structure in the first place.

The short version (why this matters)

After an IRA first funds a multi-member LLC, that LLC becomes a “disqualified entity.”
Once that happens, the IRA is no longer allowed to put new money into it, including annual contributions.

This isn’t a custodian rule or a preference. It comes straight out of how the IRS treats ownership and transactions between an IRA and entities it controls.

The key case that clarifies this is Swanson v. Commissioner.

Step 1: What Swanson v. Commissioner actually said

In Swanson, the Tax Court said:

When an IRA creates and funds a brand-new company, that initial funding is allowed.
Before the company exists, there is no relationship yet — so no prohibited transaction.

So far, so good. This is why initial capitalization of an IRA LLC is permitted.

But the court also made something else very clear.

Once the LLC exists and the IRA owns it, the relationship has changed.

At that point:

• The IRA owns the LLC

• The IRA owner controls the LLC (as manager)

• The LLC is now considered an entity owned and controlled by a disqualified person

That status change is the whole ballgame.

Step 2: What a “disqualified entity” means

Under IRC §4975, an IRA is not allowed to transact with:

• The IRA owner, or

• Any entity the IRA owner controls, or

• Any entity the IRA already owns 50% or more of

After initial funding, a multi-member IRA LLC falls squarely into that category.

From the IRS’s perspective, the LLC is no longer a neutral investment.
It’s now effectively an extension of the IRA’s control.

So future transactions between:

• the IRA → and →

• the LLC it already owns

are no longer “investments.”

They are transactions with a disqualified entity.

Step 3: Why additional contributions are the problem

A common client question is:

“Why can’t I just put my annual IRA contribution into the LLC?”

Because that would be:

A new transfer of money from the IRA to an entity it already controls.

Legally, that is treated as:

• an extension of credit, or

• a contribution to a controlled entity, or

• a transfer of plan assets to a disqualified entity

All of those are prohibited transactions once the relationship already exists.

The IRS allows:

• One clean, one-time capitalization (when the entity does not yet exist)

It does not allow:

• repeated capital infusions into an entity the IRA already owns and controls

That’s exactly what annual contributions would be.

Step 4: Why this applies specifically to multi-member IRA LLCs

This issue shows up most clearly with multi-member IRA LLCs because:

• Ownership percentages are fixed at formation

• Additional capital contributions change economics, ownership value, or control

• The IRS sees these as ongoing related-party transactions

With a single-member IRA LLC, best practice is:

• The IRA contributes to the IRA

• The IRA then invests into the LLC as needed (via the custodian)

But with a multi-member structure, once the LLC is funded:

• The LLC must live off its own income

• Or receive capital from non-disqualified third parties, not the IRA

The IRA can’t keep “topping it up.”

Step 5: A simple analogy clients usually get immediately

Think of it like this:

At birth, the LLC is a newborn with no relationships.
Your IRA gives it its first funding — that’s allowed.

Once the LLC grows up and your IRA owns it:

• The IRS says, “You can’t keep passing money back and forth inside the family.”

At that point:

• The IRA owns the company

• The company is no longer an arm’s-length investment

• Additional funding becomes self-dealing

Summary

• Swanson v. Commissioner allows initial funding of an IRA-owned LLC

• After that funding, the LLC becomes a disqualified entity

• Once disqualified, the IRA may not make additional contributions to it

• That includes annual IRA contributions

• This is why multi-member IRA LLCs must be capitalized correctly up front

This is not a loophole, and it’s not a gray area.
It’s a structural rule that comes directly from how the IRS defines control and prohibited transactions.

There are structures that allow you to combine IRA funds between multiple individuals, but it starts with each individual having their own IRA LLC.
