A multi-member IRA LLC, where two or more IRAs each hold a membership interest, is technically possible but carries significant administrative complexity and compliance risk. This is not a structure Self-Directed Plans supports or recommends. The information below explains why.
In a partnership IRA LLC, each participating IRA owns a percentage of the LLC's membership interest. The ownership split is established at formation, for example, 50/50 or 70/30, and recorded in the operating agreement.
The ownership split is permanent. Once the partnership percentage is established at formation, it cannot be changed. Every contribution of new funds into the LLC and every distribution taken out must be allocated in exact proportion to the original ownership split. If one party contributes more than their proportional share, or if distributions are taken unevenly, that imbalance is treated as one partner purchasing or selling membership equity to the other. In an IRA context, that is a transaction between two IRAs. Depending on who holds those IRAs, it is potentially a prohibited transaction.
Partnership tax filing is required. A multi-member LLC is classified as a partnership for federal tax purposes, which triggers an annual Form 1065 partnership return. This adds cost and administrative overhead that two separate single-member LLCs do not carry. The 1065 must correctly allocate income, gain, loss, and deduction to each member IRA in proportion to ownership every year, without exception.
Disqualified person exposure is elevated. When the two IRAs are held by spouses, lineal family members, or business partners who are disqualified persons to each other under IRC Section 4975(e)(2), every interaction within the shared entity must be scrutinized for self-dealing. A misstep, including an uneven contribution or distribution, can trigger a prohibited transaction and disqualify the IRA.
Life events create structural problems. The partnership structure becomes particularly difficult to manage when circumstances change:
Any of these events may require dissolving the partnership, often at an unfavorable time.
If you wish to proceed with a multi-member IRA LLC despite these risks, do so only with a qualified tax attorney involved in every stage: initial setup, annual administration, and any significant change to the plan or its investments. This structure cannot be safely self-managed.
Two separate self-directed plans, each with its own single-member LLC or Trust, accomplish the same investment goals without the partnership filing requirement, without the fixed ownership constraints, and without the prohibited transaction exposure. Both plans can invest in the same assets side by side. Each remains independently flexible.
That is the structure Self-Directed Plans recommends and supports.
