Prohibited Transactions
Common Disqualified Person Mistakes That Cost IRA Investors Everything
The disqualified person mistakes that destroy Self-Directed IRAs are not theoretical compliance technicalities. They are predictable errors that real investors make in real transactions, often without realizing the compliance consequence until it is too late to undo. This guide covers the most costly disqualified person errors in SDIRA investing — how each happens, why it triggers prohibited transaction status, and how to prevent it with a pre-transaction compliance process.
The common disqualified person mistakes ira investors make most frequently share a common characteristic: they all involve investors who knew the prohibited transaction rules in general terms but did not apply them carefully enough to the specific facts of their transaction. The investor who knows their spouse is a disqualified person but hires their spouse’s property management company anyway — because the company is well-run and the price is fair — has made the most predictable mistake in SDIRA compliance. The investor who lends IRA funds to their child’s business because it seems like a good investment has made the same mistake. The investor whose IRA co-invests with their parents in a deal where the parents together hold 55 percent of the investment entity has made a more subtle version of the same mistake.
These ira related party mistakes are not made by investors who ignore the rules. They are made by investors who understand the rules but apply them imprecisely. This guide is designed to close that gap by presenting the mistakes in the specific, concrete form in which they actually occur — not as abstract rule violations but as the actual transaction scenarios that produce prohibited transaction findings.

Mistake 1: Hiring a Spouse’s or Child’s Company to Manage IRA Property
This is the single most common disqualified person pitfalls sdira investors encounter. The IRA owns a rental property. The IRA owner’s spouse runs a property management company. The company is competent, the price is fair, and using family is convenient. The transaction feels normal because in any other context it would be normal. Inside an IRA, it is a prohibited transaction.
The ira compliance mistakes family deals generate most frequently involve service arrangements precisely because investors evaluate the service arrangement on its commercial merits rather than its compliance status. Whether the property management company charges market rates does not affect the prohibited transaction analysis. Whether the company does excellent work does not affect it. The prohibited transaction is the transaction itself — between the IRA and an entity that is either directly a disqualified person or a disqualified entity because disqualified persons own 50 percent or more of it.
The prevention is straightforward: every service provider engaged for IRA investments must be an independent third party with no disqualified person ownership. Before engaging any contractor, management company, attorney, CPA, or other service provider for IRA investment purposes, confirm their ownership structure has no disqualified person ownership at or above the 50 percent threshold. Document this confirmation in writing.
Mistake 2: Lending IRA Funds to a Child’s or Parent’s Business
Private lending through a Self-Directed IRA is one of the most popular alternative investment strategies. The IRA owner evaluates loan opportunities, and a child who runs a business or a parent who owns real estate presents what looks like a strong lending opportunity — known borrower, comfortable with the collateral, confident in repayment. The loan is at market interest rates. It seems like a legitimate investment.
It is not. The related party transaction mistakes involving private lending to disqualified persons represent some of the most expensive prohibited transaction findings in SDIRA compliance because private loans are often for significant amounts and the disqualification consequence applies to the entire IRA. A $200,000 private loan to an adult child’s business, executed from a $600,000 IRA, results in the entire $600,000 IRA being treated as a distribution — not just the $200,000 loan amount.
The complete prohibition applies regardless of whether the loan is fully secured, at above-market interest rates, personally guaranteed by third parties, or structured in every other way as a strong commercial loan. The prohibited transaction is the lending to a disqualified person itself. No commercial structuring protects against it.
Mistake 3: Purchasing Property That a Family Member Wants to Occupy
An IRA owner whose adult child is looking for a place to live sees an opportunity: the IRA purchases a rental property, the child rents it at market rate, the IRA earns rental income, and the family member has housing. The rental is at fair market value. The transaction looks like a normal arms-length rental arrangement.
The sdira disqualified party errors that involve residential rental to disqualified persons are prohibited regardless of the rental rate. The IRA cannot lease property to a disqualified person, period. Renting to a disqualified family member at market rate is prohibited. Renting to them at above-market rate is prohibited. Renting to them at any rate is prohibited. The exclusive benefit rule requires that IRA assets benefit the IRA itself — any use of IRA assets that provides housing, investment return capture, or any other benefit to a disqualified person is a prohibited transaction.
Mistake 4: Using IRA Real Estate for Personal Vacation or Personal Use
The IRA owns a vacation property as an investment rental. The property has vacancy periods when it is not rented. The IRA owner uses the property during a vacancy period — rationalizing that the property would otherwise sit empty and that the personal use does not cost the IRA anything. This is a prohibited transaction.
The personal use prohibition applies to all IRA-owned property regardless of whether the property would otherwise be generating income during the period of personal use. The exclusive benefit rule does not have an exception for incidental personal use during vacancies. A single night’s personal use of IRA-owned real estate creates a prohibited transaction finding. The self directed ira family errors that involve vacation property personal use are among the most common IRS findings in SDIRA examinations because vacation properties are inherently personal-use-adjacent and the temptation to use them is constant.
Mistake 5: Buying Property from Parents or Selling to Children at Any Price
An IRA owner wants to purchase an investment property from their parents. The parents are willing to sell at fair market value — confirmed by an independent appraisal. The transaction is commercially structured with all standard documentation. The price is demonstrably fair. The IRA executes the purchase.
This is a prohibited transaction. The purchase of property from a disqualified person is prohibited regardless of the pricing. There is no exception in IRC §4975 for transactions with disqualified persons that are at fair market value. The prohibited transaction is the transaction itself between the IRA and the disqualified person — the pricing of the transaction is irrelevant to the prohibited transaction analysis. This is one of the most counterintuitive aspects of the disqualified person rules and one of the most frequently misunderstood.
The inverse is equally prohibited: the IRA cannot sell property to a disqualified person at any price. An IRA that owns real estate and wants to sell it cannot sell it to a family member regardless of whether the sale is at, above, or below market value.
Mistake 6: Overlooking the Entity Attribution Rules
An IRA owner wants to invest in a real estate development LLC managed by a business associate. The IRA owner runs the 50 percent combined ownership test on the LLC and finds that their personal ownership interest is 25 percent. No other disqualified persons appear in the LLC. The IRA invests.
Three months later it emerges that the IRA owner’s adult child purchased a 30 percent interest in the same LLC after the IRA’s initial investment. The combined disqualified person ownership is now 55 percent. The LLC is retroactively a disqualified entity from the date the child’s ownership brought the combined total above 50 percent. Every transaction between the IRA and the LLC after that date is a prohibited transaction.
The ira compliance mistakes family deals involving entity attribution require not just checking ownership at the time of the initial IRA investment but maintaining ongoing awareness of ownership changes in entities where the IRA has invested. If a disqualified person acquires an interest in a previously non-disqualified entity after the IRA has invested, the IRA’s existing investment relationship with that entity becomes problematic on an ongoing basis. This is a case where the common disqualified person mistakes ira investors make are less about the initial investment decision and more about failing to monitor ownership changes after the investment is made.
Mistake 7: Providing Personal Expertise as a Service to IRA Investments
An IRA owner who is a licensed contractor purchases rental real estate through their IRA. When the property needs repairs, the owner personally performs the work — rationalizing that this saves the IRA money and that their personal expertise benefits the IRA. The work is of professional quality. No compensation changes hands.
This is a prohibited transaction. The provision of personal labor and expertise to IRA investments constitutes a service to the plan that creates both a self-dealing prohibited transaction and a personal benefit to the IRA owner through the avoidance of costs that would otherwise be paid to a third-party contractor. The absence of direct compensation does not eliminate the prohibited transaction — the benefit to the IRA owner is the avoided cost and the benefit to the IRA is the personal services received, both of which constitute prohibited self-dealing.
All services for IRA investments must be performed by independent third-party providers who are not disqualified persons. The IRA owner’s professional expertise and personal labor are not assets that can be deployed for IRA investments regardless of how beneficial they would be to the IRA’s returns.
Mistake 8: Assuming “Arms-Length” Protects Against Prohibited Transaction Findings
The most pervasive of the sdira disqualified party errors is the belief that a transaction with a disqualified person is permissible if it is conducted on fair, commercial, arms-length terms. This belief is wrong, and it produces prohibited transactions across every category of disqualified person mistake.
IRC §4975 does not prohibit unfair transactions with disqualified persons while permitting fair ones. It prohibits specific types of transactions between IRAs and disqualified persons regardless of the commercial terms. The types of prohibited transactions under IRC §4975(c) include any sale, exchange, or leasing of property; any lending of money or other extension of credit; any furnishing of goods, services, or facilities; and any transfer to or use by a disqualified person of IRA assets. These prohibitions apply to all transactions of these types with disqualified persons, not only to unfair or commercially unreasonable ones.
The arms-length framing matters in some IRA compliance contexts — it is relevant to the question of whether a transaction with a non-disqualified party creates self-dealing concerns — but it does not create a safe harbor for transactions with disqualified persons. A disqualified person transaction is prohibited at market value and below market value and above market value equally.
Building a Pre-Transaction Compliance Process That Prevents These Mistakes
The related party transaction mistakes that produce the most costly prohibited transaction findings are all preventable with a consistent pre-transaction compliance process. The process does not need to be long or complex — it needs to be consistently applied before every significant IRA transaction.
The three-question pre-transaction compliance check: First, is any party to this transaction a disqualified person under IRC §4975(e)(2) — either as an individual family member, fiduciary, or service provider, or as an entity failing the 50 percent combined ownership test? Second, would this transaction constitute a sale, exchange, lease, loan, service provision, or use of IRA assets for the benefit of that disqualified person in any of these ways? Third, have I documented this analysis in writing before executing the transaction?
If the answer to the first question is yes, the transaction is prohibited regardless of the answers to the other questions. If the answer to the first question is no, proceed to confirm the transaction is at arms-length fair market value terms and document the compliance analysis. For complex transactions where the disqualified person analysis is not straightforward — business partner co-investments, entity attribution questions, trust beneficiary analyses — obtain a written legal opinion from a qualified SDIRA attorney before proceeding. For the complete prohibited transaction framework that underlies all of these compliance requirements, see our guide on IRA prohibited transaction rules.
FAQ
If I discover I have made one of these mistakes, what do I do immediately?
Stop all activity in the affected IRA immediately and consult a qualified SDIRA attorney before taking any further action. Do not attempt to reverse, correct, or conceal the transaction without legal guidance. Do not make additional IRA investments while the prohibited transaction question is unresolved. Document everything you know about the transaction — when it occurred, who was involved, what the transaction was — and provide it to your attorney at the first meeting. Time matters because the IRS statute of limitations considerations and any potential remediation options depend on the specific facts and timing of the violation.
Can a prohibited transaction be undone if discovered quickly after execution?
The IRA disqualification under IRC §4975 is effective as of January 1 of the year the prohibited transaction occurred, regardless of when it is discovered or when corrective action is taken. There is no cure mechanism for IRA prohibited transactions comparable to the correction programs available for qualified plan failures. What a quick discovery may affect is the availability of certain penalty relief programs and the ability to limit ongoing violations by restructuring arrangements. These options require specific legal analysis. The takeaway for investors is that the only effective strategy is prevention — there is no reliable remedy after the fact.
Is there any dollar threshold below which a prohibited transaction does not disqualify the IRA?
No. The IRA disqualification consequence applies to any prohibited transaction regardless of the amount involved. A $500 prohibited transaction — paying a disqualified family member’s company for a minor repair on an IRA-owned property — disqualifies the entire IRA just as a $500,000 transaction would. The amount of the transaction affects the tax liability only insofar as it affects the total account balance that is deemed distributed, but the disqualification itself is triggered by any prohibited transaction regardless of size.
Does the IRS actively look for these mistakes or only find them incidentally?
Both. The IRS has increased its targeted examination of self-directed IRA structures and specifically trains examiners to look for the categories of prohibited transactions described in this guide. IRS examination programs targeting SDIRA compliance have expanded in recent years in response to the growth of SDIRA investing and the documented pattern of prohibited transaction violations in this space. Beyond targeted examinations, prohibited transactions are also discovered incidentally when the IRA owner or related parties are audited for other tax issues, when third parties involved in prohibited transactions cooperate with IRS inquiries, and when Form 5498 data triggers follow-up on valuation or reporting anomalies.
Does using a financial advisor or SDIRA custodian protect me from these mistakes?
No. As covered in our guide on what SDIRA custodians are and are not responsible for, SDIRA custodians process investor-directed transactions without evaluating their compliance with the prohibited transaction rules. A custodian that processes a prohibited transaction direction does not protect the investor from the tax consequences. Financial advisors who do not specifically specialize in SDIRA compliance are similarly not reliable safeguards against disqualified person errors. The compliance responsibility is entirely the investor’s, regardless of which professionals are involved in the transaction.
