Who Is a Disqualified Person in a Self-Directed IRA: Complete IRC §4975 Guide
The disqualified person definition under IRC §4975 determines who cannot transact with your Self-Directed IRA without creating a prohibited transaction. Getting this definition exactly right is not optional — every SDIRA investment must be analyzed against it before execution. This complete guide covers every category of disqualified person, the entity ownership rules that extend the definition beyond individuals, and the specific analysis required for common SDIRA transaction structures.
The phrase “disqualified person” appears in nearly every discussion of Self-Directed IRA compliance, but it is frequently described incompletely. Many investors know that family members are disqualified but do not know exactly which family members, how entities controlled by family members are treated, or how the definition applies to business partners and professional relationships. This incomplete understanding of who is a disqualified person ira creates the conditions for prohibited transactions that are executed in good faith by investors who simply did not know the full scope of the rule.
The disqualified persons self directed ira definition under IRC §4975(e)(2) is a statutory list of specific categories. It is not a general prohibition on conflicts of interest or related-party transactions — it is a precise legal definition that either applies or does not apply to a specific party based on their relationship to the IRA. Understanding the definition precisely means knowing exactly who is on that list and, equally importantly, who is not.

The Complete IRC §4975 Disqualified Person Definition
IRC §4975(e)(2) defines a disqualified person with respect to a plan — which includes an IRA — as any of the following:
A fiduciary of the plan. For an IRA, the fiduciary is the IRA owner themselves. In a checkbook control structure, the IRA owner serving as LLC manager is also a fiduciary. The IRA custodian is a fiduciary in their administrative capacity. Any investment manager with discretionary authority over IRA assets would be a fiduciary.
A person providing services to the plan. Anyone who provides services to the IRA is a disqualified person. This category is broader than it might first appear. The IRA custodian providing administrative services is a disqualified person. A CPA who prepares the IRA’s Form 990-T is providing services to the plan and is technically a disqualified person. An attorney who provides legal services to the IRA LLC is a disqualified person. This categorization matters for understanding why these service providers cannot be transaction counterparties even if they are professionally unrelated to the IRA owner.
An employer of any plan participants. For an IRA (as opposed to an employer plan), there is typically no employer-employee relationship involved. This category applies primarily to employer-sponsored retirement plans rather than IRAs and has limited practical significance for most SDIRA investors.
An employee organization whose members are covered by the plan. Again, primarily relevant for employer plans rather than individual IRAs.
An owner of 50 percent or more of the employer. For IRAs, this applies to any entity in which the IRA owner holds a 50 percent or greater interest. If the IRA owner holds 60 percent of a real estate LLC personally, that LLC is a disqualified person with respect to the IRA. The IRA cannot transact with that LLC in any capacity.
A family member of the IRA owner. IRC §4975(e)(2)(F) defines family members as the IRA owner’s spouse, ancestor, lineal descendant, and any spouse of a lineal descendant. This is the category most commonly discussed and most commonly misunderstood. The precise definition is covered in the next section.
A corporation, partnership, trust, or estate in which disqualified persons hold 50 percent or greater combined interest. This is the entity attribution rule that extends the disqualified person definition beyond individuals to entities they control. It is one of the most important and most frequently overlooked aspects of the definition.
An officer, director, 10 percent or more shareholder, or highly compensated employee of a 50 percent disqualified entity. Officers, directors, and significant shareholders of entities that are already disqualified persons are themselves disqualified persons with respect to the IRA.
A 10 percent or more partner or joint venturer of a 50 percent disqualified entity. Partners and joint venturers in disqualified entities are themselves disqualified persons.
The Family Member Disqualified Person Definition: Exactly Who Is Included
The ira family member rules under the disqualified person definition cover a specific set of family relationships. This is where precision matters most because the definition includes some relatives and excludes others in ways that surprise investors who assume the rule covers all family broadly.
Spouse. The IRA owner’s current legal spouse is a disqualified person. This applies to legally recognized marriages. The spouse’s family relationships are not independently relevant to the IRA owner’s disqualified person analysis — the IRA owner’s in-laws are not disqualified persons by virtue of being the spouse’s family, though they may be disqualified if they fall into another category such as a 50 percent entity owner.
Ancestors. The IRA owner’s parents, grandparents, and great-grandparents are disqualified persons. The ancestor relationship extends upward through all generations.
Lineal descendants. The IRA owner’s children, grandchildren, and great-grandchildren are disqualified persons. The lineal descendant relationship extends downward through all generations. Adopted children are treated as lineal descendants for this purpose.
Spouses of lineal descendants. The spouses of the IRA owner’s children, grandchildren, and great-grandchildren are disqualified persons. A son-in-law or daughter-in-law is a disqualified person because they are the spouse of the IRA owner’s lineal descendant.
The ira prohibited person list notably does not include siblings. The IRA owner’s brother and sister are not disqualified persons under the statutory definition. This is one of the most frequently asked questions in SDIRA compliance, and the answer is covered in depth in our companion article on are siblings disqualified persons under IRA rules. Uncles, aunts, cousins, nieces, nephews, and other extended family members are also not disqualified persons under the statutory definition. For the complete analysis of parents, children, spouses, and lineal family members, see parents, children, spouses and lineal family in SDIRA rules.
The Entity Attribution Rules: When Business Ownership Creates Disqualified Status
The who cannot transact with ira analysis extends beyond individual family members to entities through the attribution rules in IRC §4975(e)(2)(G) and (H). These rules are critical for SDIRA investors who own businesses or investment entities personally, because those entities may be disqualified persons with respect to the IRA even if no individual family member is directly involved in the transaction.
The 50 percent combined ownership test. Any corporation, partnership, trust, or estate in which disqualified persons hold combined interests of 50 percent or more is itself a disqualified person with respect to the IRA. The combined interest includes the IRA owner, their spouse, their ancestors, their lineal descendants, and any other person who is already a disqualified person. If the IRA owner holds 30 percent of a corporation and their spouse holds 25 percent, their combined 55 percent interest makes that corporation a disqualified person even though neither individual alone crosses the 50 percent threshold.
The attribution aggregation rule. All disqualified persons’ ownership interests are aggregated for the 50 percent test. This means an IRA owner who holds 30 percent of a company personally, whose parent holds 15 percent, and whose child holds 10 percent has 55 percent combined disqualified person ownership — making the company a disqualified person — even though no single individual holds 50 percent.
Cascading disqualified entity interests. Once an entity is a disqualified person under the 50 percent test, its officers, directors, 10 percent or more shareholders, and 10 percent or more partners are also disqualified persons. This cascading effect can extend the disqualified person network significantly. An investor who runs a real estate investment company with outside partners, some of whom hold 10 percent or more interests, may find that multiple individuals and entities in their professional network are technically disqualified persons with respect to their IRA.
The Self Directed IRA Disqualified Parties Analysis: A Practical Framework
The self directed ira disqualified parties analysis that must be conducted before every significant SDIRA investment follows a structured process:
Step 1: Identify every party to the proposed transaction. For a real estate purchase, this includes the seller, the title company, any lender, the property manager, any contractors already engaged, and any investment partners. For a private loan, this includes the borrower, any guarantors, and any other parties to the loan documents. For a private equity investment, this includes the fund manager, general partner, and any known co-investors.
Step 2: Check each party against the individual disqualified person categories. For each individual party: are they the IRA owner? The IRA owner’s spouse? An ancestor of the IRA owner? A lineal descendant? A spouse of a lineal descendant? Any yes answer means that party is a disqualified person and the transaction is prohibited if it is between the IRA and that person.
Step 3: Check each entity party against the 50 percent combined ownership test. For each entity party: what percentage of that entity do disqualified persons combined own? If the combined disqualified person ownership is 50 percent or more, the entity is a disqualified person and transactions between the IRA and that entity are prohibited.
Step 4: Check the cascading officer and director rules for any disqualified entities. For any entity identified as disqualified in Step 3: are there officers, directors, 10 percent shareholders, or 10 percent partners in that entity who would be involved in the transaction? If so, those individuals are also disqualified persons.
Step 5: Document the analysis. Create a written record confirming that the analysis was conducted, the parties reviewed, and the conclusion reached. For transactions with clean third-party counterparties this document is brief. For more complex transactions involving professional networks, the analysis may be longer. Either way, the written record demonstrates due diligence if the transaction is ever questioned.
Common Situations Where the Disqualified Person Analysis Is More Complex
Lineal descendants ira rules and the entity attribution rules create specific complexities in common SDIRA investing scenarios that are worth addressing directly.
Investing with a business partner who is married to a disqualified person. If the IRA owner’s business partner is married to the IRA owner’s sibling, the business partner themselves is not a disqualified person (siblings are not disqualified, and the sibling’s spouse is not directly connected to the IRA owner’s disqualified person list). However, if the business partner holds 50 percent or more of an entity in which the IRA owner or their disqualified persons also have an interest, the attribution rules may apply.
Investing in a fund managed by a professional contact. If the IRA owner’s professional friend manages a private equity fund and the IRA wants to invest as a limited partner, the fund manager is likely a disqualified person as a person providing services to the plan or as a fiduciary if they have investment authority. The specific analysis depends on the exact structure of the fund and the nature of the manager’s authority over IRA assets.
Participating in a real estate syndication with family members as co-investors. If the IRA owner’s parents or children are also investing in the same real estate syndication as co-limited partners, the IRA’s co-investment alongside disqualified persons in the same entity requires careful analysis. The mere co-ownership of interests in a fund or syndication by both the IRA and disqualified persons is not automatically prohibited, but the specific facts of the arrangement determine whether a prohibited transaction exists.
FAQ
If a disqualified person was involved in a transaction before the IRA was established, does that create a prohibited transaction?
Prohibited transactions are evaluated based on the relationship of the parties at the time of the transaction. Transactions that occurred before the IRA existed cannot be prohibited transactions with respect to the IRA. However, if a disqualified person’s prior involvement created an ongoing relationship — for example, the IRA owner’s parent previously lent money to a property the IRA now wants to purchase, and that loan is still outstanding — the ongoing relationship requires analysis to determine whether the current transaction creates prohibited transaction exposure.
Does the disqualified person definition apply the same way to Roth IRAs as to Traditional IRAs?
Yes. The IRC §4975 prohibited transaction rules and the disqualified person definition apply equally to Traditional IRAs, Roth IRAs, SEP IRAs, and SIMPLE IRAs. The tax treatment of the accounts differs, but the prohibited transaction framework is identical across all IRA account types.
What if I discover a party to a completed transaction was a disqualified person I did not know was disqualified?
Discovering a prohibited transaction after it has occurred is a serious situation that warrants immediate consultation with a qualified SDIRA attorney. The prohibited transaction may have already disqualified the IRA. Whether remediation is available depends on the specific facts of the transaction, the nature of the disqualified person relationship, and the timing of the discovery. Acting quickly with qualified counsel is the only appropriate response.
Is a business partner who is not a family member and does not own an entity with me a disqualified person?
A business partner who is not a family member and has no entity ownership overlap with the IRA owner or their disqualified persons is generally not a disqualified person. Business relationships and professional relationships alone do not create disqualified status. The disqualified person definition is based on specific legal categories — family relationships, fiduciary status, ownership percentages — not on the breadth or depth of a professional relationship. A close business partner of many years who has no family connection and no entity ownership connection to the IRA owner is typically not a disqualified person.
Can a disqualified person ever become a non-disqualified person with respect to the IRA?
In some circumstances, yes. If the IRA owner divorces their spouse, the former spouse is no longer the IRA owner’s spouse and therefore no longer a disqualified person on that basis (though they may remain a disqualified person on another basis such as entity ownership). If a disqualified entity’s ownership structure changes so that disqualified persons no longer hold 50 percent combined interest, the entity ceases to be disqualified. For family relationships based on birth or adoption — parents, children, grandchildren — the disqualified status is permanent regardless of the relationship’s current quality.
