A father, 61, purchased a lake house through his self-directed IRA as a rental investment property, intending the rental income to flow back into the retirement account tax deferred. His adult son has asked to use the property for a free weekend getaway with his own family, unaware that doing so could jeopardize the entire IRA's tax advantaged status.

Why Family Members Can't Use IRA Owned Property

The IRS classifies certain relatives, including a lineal descendant like a son or daughter, as "disqualified persons" under Internal Revenue Code Section 4975, meaning the IRA cannot transact with them in ways that provide a personal benefit. Letting a disqualified person stay at a property owned by the IRA, even for a single free weekend, is generally considered a prohibited transaction because it provides a personal benefit outside the account.

That rule applies regardless of whether the son pays fair market rent or stays for free. Any personal use by a disqualified person, even briefly, risks the same consequence.

What Happens If The Rule Gets Broken

A prohibited transaction disqualifies the entire IRA retroactive to January 1 of the year the violation occurred, meaning the full account balance becomes treated as a taxable distribution. For an account holder under 59 and a half, that also triggers a 10% early withdrawal penalty on top of ordinary income tax owed on the full balance, not just the value of the property involved.

For a lake house held inside a retirement account meant to grow tax deferred for another decade, a single weekend stay could unwind years of tax advantaged growth in one enforcement action if the IRS discovers the violation.

Who Actually Counts As A Disqualified Person

Disqualified persons include the IRA owner, their spouse, lineal ascendants and descendants like parents and children, spouses of those descendants, and any fiduciary or service provider to the account, but notably do not include siblings, cousins, or friends. That distinction matters, since it means the exact same property could potentially be used by a sibling under certain arrangements in ways that wouldn't be permitted for a son or daughter.
