Can My Business Partner Transact With My Self-Directed IRA?

The business partner self directed ira rules question is one of the most practically significant compliance questions SDIRA investors face because business partners are frequently involved in the same investment spaces where IRA capital is deployed. A partner who develops real estate, runs a private lending operation, manages investment funds, or owns businesses creates constant opportunities for the IRA and the partner’s activities to intersect. Understanding exactly when that intersection is permitted and when it creates prohibited transaction exposure is essential for any SDIRA investor with active business relationships.

The core legal question is whether the business partner qualifies as a disqualified person under IRC §4975(e)(2). If they do not, transactions between the IRA and the partner are not automatically prohibited. If they do, every transaction between the IRA and that partner — regardless of commercial terms, regardless of intent — is a prohibited transaction with the full consequences of IRA disqualification. The analysis requires examining the partner’s relationship to the IRA owner, the ownership structure of any shared entities, and the specific nature of the proposed transaction.

Is a Business Partner a Disqualified Person?

The ira transaction with partner analysis begins with the threshold question: is the business partner a disqualified person under IRC §4975(e)(2)? A business partner who is not a disqualified person can transact with the IRA subject to the arms-length requirements that apply to all IRA investments. A business partner who is a disqualified person cannot transact with the IRA in any capacity.

Business partners are not disqualified persons based on the partnership relationship alone. The disqualified person definition covers specific legal categories — family relationships, fiduciary status, entity ownership percentages — not business relationships generally. A long-time business partner who has no family connection to the IRA owner, no ownership overlap in shared entities, and no fiduciary role with respect to the IRA is not a disqualified person regardless of the depth or duration of the business relationship.

However, several paths exist through which a business partner can become a disqualified person:

The partner is also a family member. If the business partner is the IRA owner’s spouse, parent, child, or other covered family member, the family relationship makes them a disqualified person independent of the business relationship. For the complete family member analysis, see our guide on lineal family disqualified person rules for SDIRAs.

The partner provides services to the IRA. A business partner who also serves in a services capacity for the IRA — managing IRA investments, providing legal or financial advice specifically to the IRA, acting as the investment manager for IRA assets — is a disqualified person as a person providing services to the plan under IRC §4975(e)(2)(B).

The partner and IRA owner share entity ownership that creates disqualified entity status. This is the most important and most frequently misunderstood path. When the IRA owner and their business partner jointly own an entity, the 50 percent combined disqualified person ownership test must be evaluated. If disqualified persons together own 50 percent or more of the shared entity, the entity itself becomes a disqualified person — and the partner who manages or has significant interest in that disqualified entity may also become disqualified under the cascading officer and director rules. For the complete entity attribution analysis, see our guide on entity attribution rules for disqualified persons.

The Partner Disqualified Person IRA Analysis: Shared Entity Ownership

The partner disqualified person ira scenario that most frequently creates compliance problems is co-investment in shared business entities. When the IRA owner and a business partner own interests in the same LLC, corporation, or partnership, every IRA transaction involving that entity requires the 50 percent combined ownership analysis.

The combined ownership test aggregates all disqualified persons’ interests in the entity. The IRA owner is a disqualified person. Their spouse is a disqualified person. Their parents and children are disqualified persons. All of these individuals’ interests in the shared entity are combined for the 50 percent test. The business partner’s interest is not counted in the combination because the partner is not (assuming) a disqualified person.

Examples make this concrete:

Scenario A: IRA owner holds 40 percent of an LLC. Business partner holds 60 percent. No other disqualified persons hold interests. The IRA owner’s 40 percent disqualified person ownership does not reach 50 percent. The LLC is not a disqualified entity. The IRA can invest in the LLC subject to arms-length terms.

Scenario B: IRA owner holds 30 percent of an LLC. IRA owner’s spouse holds 25 percent. Business partner holds 45 percent. Combined disqualified person ownership: 55 percent. The LLC is a disqualified entity. The IRA cannot invest in it.

Scenario C: IRA owner holds 40 percent of an LLC. IRA owner’s adult child holds 15 percent. Business partner holds 45 percent. Combined disqualified person ownership: 55 percent. The LLC is a disqualified entity even though the partner holds a minority interest.

The ira related party business partner analysis must be performed on every entity where shared ownership exists before any IRA transaction involving that entity is executed.

Can IRA Invest With Business Partner: The Co-Investment Question

The can ira invest with business partner question arises when both the IRA and the business partner want to invest in the same opportunity — a real estate deal, a private lending transaction, a fund — either as co-investors or through a shared entity.

Co-investment between the IRA and a non-disqualified business partner in a third-party investment is generally permitted provided the structure does not create a transaction between the IRA and the partner. The IRA investing as a limited partner in a real estate fund where the business partner is also a limited partner, without the partner having any control over the fund, is different from the IRA investing in an entity the business partner manages or controls.

The self directed ira partnership rules governing this distinction are centered on the concept of a direct transaction between the IRA and a disqualified person. If the IRA and the partner both invest in a third-party managed fund as passive co-investors, there is no transaction between them — each is separately transacting with the fund. If the IRA invests in an entity managed or controlled by the partner, the investment is a transaction between the IRA and the partner’s controlled entity, which triggers the prohibited transaction analysis.

The Co-Investment Structuring Principle

IRA co-investment with a business partner is most clearly permissible when both parties invest as passive investors in a third-party managed vehicle where neither controls the investment decisions. It becomes progressively more complex as the partner’s control over the investment increases. When the partner manages the investment vehicle, has discretionary authority over how capital is deployed, or receives compensation from the investment vehicle in which the IRA is a co-investor, the prohibited transaction analysis becomes more detailed and typically requires specific legal guidance before proceeding.

Self Directed IRA Partnership Rules: When the Partner Manages IRA Investments

The scenario where a business partner manages IRA investments — whether as the general partner of a fund the IRA invests in, as the manager of an LLC the IRA co-owns, or as a paid investment advisor for the IRA — requires the most careful analysis because the management role itself may create disqualified person status.

A business partner who acts as the investment manager for the IRA — making investment decisions on behalf of the IRA with discretionary authority — is a fiduciary of the IRA under IRC §4975(e)(2)(A) and is therefore a disqualified person. Once the partner is disqualified as a fiduciary, no transaction can occur between the IRA and the partner in any capacity.

A business partner who manages a fund or LLC in which the IRA is a passive investor — without having any discretionary authority over the IRA’s investment decision or management — has a more complex analysis. The partner’s management role in the fund does not automatically make them a fiduciary of the IRA. However, if the fund’s structure gives the partner control over IRA assets in any meaningful sense, the fiduciary question requires specific analysis.

The conservative and safest approach when a business partner is involved in managing investments in which the IRA participates is to obtain a written legal opinion from a qualified SDIRA attorney confirming the structure does not create a prohibited transaction before the IRA commits capital. The cost of that opinion is modest compared to the cost of a prohibited transaction finding on a significant IRA investment.

Practical Framework for Business Partner IRA Transactions

The co investing with partner ira compliance framework that protects against prohibited transaction exposure follows a consistent analytical sequence for every proposed transaction:

Step 1: Confirm the partner has no family relationship to the IRA owner that creates disqualified status. Partners who are also family members are disqualified regardless of the business relationship.

Step 2: Confirm the partner has no fiduciary role or services provision relationship with the IRA that creates disqualified status. Partners who manage IRA investments, advise the IRA, or provide services specifically to the IRA are disqualified as fiduciaries or service providers.

Step 3: Map all shared entity ownership and run the 50 percent combined disqualified person ownership test on each shared entity. If any shared entity fails the test, it is a disqualified entity and IRA transactions with it are prohibited.

Step 4: Confirm the proposed transaction is structured so that the IRA is transacting with an arms-length third party rather than directly with the partner or a partner-controlled entity. The transaction must be at fair market value with no benefit flowing to any disqualified person.

Step 5: Document the analysis in writing before executing the transaction. The written compliance memo is the defense if the transaction is questioned in an IRS examination.

FAQ

My business partner and I want to buy a property together, with my IRA owning 50 percent and my partner personally owning 50 percent. Is this permitted?

This structure — the IRA and the business partner as direct co-owners of a property — is a prohibited transaction if the partner is a disqualified person. If the partner is not a disqualified person, this structure has been the subject of significant legal debate and IRS scrutiny. Direct co-ownership between an IRA and any individual creates a relationship where the IRA and the co-owner must transact with each other for every operational decision — repairs, expenses, management, eventual sale. Most qualified SDIRA attorneys advise against this structure even with non-disqualified partners because of the difficulty of ensuring every operational decision satisfies the arms-length exclusive benefit requirement. Using a jointly owned LLC where both the IRA and the partner hold membership interests is generally a cleaner structure that isolates the compliance analysis to the entity level.

Can my IRA lend money to a business my partner and I own together?

This requires the 50 percent combined ownership analysis on the business entity. If disqualified persons combined own 50 percent or more of the business, it is a disqualified entity and the IRA cannot lend to it. If disqualified persons combined own less than 50 percent, the entity is not disqualified and the IRA can lend to it on arms-length terms. The fact that you personally have an ownership interest in the borrowing entity does not automatically make the loan prohibited if your ownership share alone is under 50 percent and no other disqualified persons’ shares push the combined total to 50 percent or above.

What if my business partner becomes a disqualified person after we have already set up a co-investment structure?

If a business partner becomes a disqualified person after an IRA co-investment structure is already in place — for example, because the IRA owner marries someone whose family member is the partner — the existing structure requires immediate compliance review. Ongoing transactions between the IRA and the now-disqualified partner may constitute prohibited transactions from the date the disqualified status arose. This is a situation requiring prompt consultation with a qualified SDIRA attorney to assess the existing structure and determine what changes are needed to avoid ongoing prohibited transaction exposure.

Does the business partner analysis change if I use a checkbook control IRA LLC?

No. The prohibited transaction analysis and the disqualified person definition apply equally regardless of whether the IRA invests through a custodian-directed transaction or a checkbook control LLC. The checkbook control structure changes the operational mechanics but does not change the underlying compliance rules. A partner who is a disqualified person with respect to the IRA cannot transact with the IRA LLC any more than they can transact with the IRA directly.

Can my business partner serve as the registered agent for my IRA LLC?

A registered agent for an LLC performs a ministerial function — receiving official legal and government correspondence on behalf of the LLC. A registered agent typically does not have any management authority, investment discretion, or fiduciary responsibility. On that basis, serving as a registered agent alone likely does not create disqualified person status. However, if the registered agent role is combined with any advisory, management, or services function for the IRA LLC, the combined role requires more careful analysis. Using a professional registered agent service rather than a business partner eliminates this question entirely and costs only $50 to $150 per year.
