Prohibited Transactions: What You Can’t Do with Your SDIRA

Understanding prohibited transactions is one of the most important parts of Self Directed IRA investing. If you need a full foundation before diving into compliance rules, start here: Self Directed IRA Guide. A prohibited transaction in a Self Directed IRA generally means an improper use of IRA assets by the IRA owner, beneficiary, or another disqualified person. These rules are designed to stop self dealing, improper personal benefit, and misuse of retirement funds.

This guide explains what a Self Directed IRA prohibited transaction is, who counts as a disqualified person, what common prohibited transaction IRA examples look like, and how to avoid mistakes that can trigger taxes, penalties, and loss of IRA status.

What Are Prohibited Transactions?

Prohibited transactions are defined under Internal Revenue Code Section 4975. In simple terms, they are transactions the IRS does not allow between an IRA and a disqualified person, or transactions where IRA assets are used for the benefit of a disqualified person.

Most self directed IRA prohibited transaction issues fall into two broad categories:

1. Direct self dealing: A direct transaction between the IRA and a disqualified person
2. Indirect benefit: A structure or arrangement that gives you or another disqualified person a present day benefit from IRA assets

The Six Core Rules

1. Sale or exchange of property: The IRA cannot buy from, sell to, or lease with a disqualified person
2. Lending money or extending credit: The IRA cannot lend to or borrow from a disqualified person
3. Furnishing goods, services, or facilities: A disqualified person cannot provide certain services to the IRA or receive them from the IRA in a prohibited way
4. Transfer, use, or benefit of IRA assets: IRA assets cannot be used by or for the benefit of a disqualified person
5. Receiving compensation: A fiduciary or disqualified person cannot receive improper compensation tied to IRA assets or transactions
6. Acting in self interest: A fiduciary cannot use IRA assets for his or her own interest or account

Who Are Disqualified Persons?

Understanding disqualified persons is essential to avoiding violations. A transaction may look reasonable on the surface and still fail because of who is involved.

Always Disqualified

The following are generally treated as disqualified persons for IRA purposes:

• You: The IRA owner
• Your spouse: Your current spouse is always disqualified
• Your lineal ancestors: Parents, grandparents, and further direct ancestors
• Your lineal descendants: Children, grandchildren, and further direct descendants
• Spouses of lineal descendants: Sons in law and daughters in law
• Fiduciaries and service providers: Depending on the role and transaction
• Certain entities you control: Including entities where ownership thresholds under the tax rules are met

Not Disqualified

These people are generally not disqualified persons under the basic IRA rules:

• Siblings: Brothers and sisters
• Extended family: Aunts, uncles, cousins, nieces, and nephews
• Friends and unrelated business contacts: Unless another disqualified person rule applies

Common Prohibited Transactions

Personal Use

You cannot live in, vacation in, store personal property in, or otherwise personally use an IRA owned asset. This is one of the clearest examples of IRA self dealing rules in action.

Selling Assets to Your IRA

You cannot transfer personally owned assets into your IRA by selling them to the IRA. That includes real estate, privately held business interests, metals you already own, or other personal assets.

Providing Services

You cannot perform labor or provide disqualifying services to IRA owned assets. That means you should not personally repair, renovate, manage, or maintain IRA property in a hands on way.

Renting to Disqualified Persons

You cannot rent IRA owned property to your spouse, parents, children, grandchildren, or entities they control if those relationships create disqualified person status.

Borrowing or Lending

No loans between you and your IRA are permitted. You also cannot personally guarantee debt for the IRA. That is why many real estate deals must use non recourse financing rather than a standard personal guarantee structure.

Commingling Funds

All income and expenses must flow directly through the IRA. You should not pay IRA expenses with personal funds, deposit IRA income to personal accounts, or reimburse yourself later.

Indirect Violations

Some prohibited transaction IRA examples are not obvious. The IRS may look at the substance of the arrangement, not just the paperwork.

Examples of indirect issues can include:

• Using a related party as a middle step to transfer an asset into the IRA
• Having an entity you control profit from work performed for the IRA
• Structuring a transaction that appears arm’s length but still gives you present day personal benefit

This is why step transaction risk matters. If multiple steps are really part of one overall plan to benefit a disqualified person, the IRS may collapse the steps and treat the arrangement as prohibited.

Penalties

The consequences can be severe. In addition to the IRA losing its intended tax treatment, the IRS also imposes excise tax rules on prohibited transactions. The initial excise tax is generally 15% of the amount involved, and if the transaction is not corrected in time, the additional tax can rise to 100% of the amount involved. :contentReference[oaicite:2]{index=2}

For IRA owners, one of the most serious outcomes is that the IRA may be treated as distributed, causing ordinary income tax on the affected value and a possible 10% early distribution penalty if the owner is under age 59½. :contentReference[oaicite:3]{index=3}

How to Avoid Violations

Simple Rule

If a transaction gives you immediate personal benefit today instead of only growing your IRA for the future, it is likely prohibited.

Maintain Separation

Treat your IRA as a completely separate legal and financial bucket. Keep the money, paperwork, ownership, and benefit lines clearly separate from your personal life.

Documentation

Maintain records of all transactions, valuations, invoices, contracts, and payment flows. Good documentation does not cure a prohibited transaction, but it can help demonstrate proper structure when the arrangement is valid.

Ask Professionals

Consult qualified advisors when uncertain. Your custodian may process documents, but that does not mean the transaction is safe. Learn how to evaluate a provider here: Choosing a Custodian.

Advanced Structures

Some investors use structures like Checkbook Control to manage transactions more efficiently, but those structures increase your compliance responsibility. Faster control does not reduce prohibited transaction risk.

Alternative Investment Structures

Strategies like Private Lending can reduce operational complexity compared to direct ownership, but the same prohibited transaction rules still apply.

Custodian Role

Your custodian processes transactions, maintains records, and handles certain reporting, but the custodian generally does not protect you from prohibited transaction mistakes or evaluate whether a deal is wise. That responsibility remains with you and your advisors.

Conclusion

Prohibited transaction rules are strict, but they are manageable when you understand the basic principle: keep IRA assets separate from present day personal benefit. Avoid self dealing, know who your disqualified persons are, and slow down whenever a transaction involves family, controlled entities, services, or unusual structuring.

Done correctly, your IRA can remain compliant while investing in powerful alternative assets for long term retirement growth.
