A man, 50, planned to lend $60,000 from his self-directed IRA to help his son-in-law launch a small logistics business, structuring it as a documented loan with interest to keep everything above board. What he didn't realize is that a son-in-law falls squarely within the IRS definition of a disqualified person, making the loan a prohibited transaction regardless of how properly it was otherwise documented.

Why A Son-In-Law Counts As Disqualified

The IRS definition of disqualified persons under Section 4975 explicitly includes spouses of an account holder's lineal descendants, meaning a son-in-law or daughter-in-law is treated the same as a biological child for these purposes. Even a well documented, interest bearing loan structured exactly like an arm's length transaction with an unrelated party is still prohibited once the borrower falls into that category.

This surprises a lot of IRA holders who assume that following normal lending best practices, market interest rate, written terms, formal documentation, is enough to satisfy IRS rules, when the relationship itself is what disqualifies the transaction regardless of how it's structured.

What The Consequence Would Have Been

Had the loan gone through, it would have been treated as a prohibited transaction, disqualifying his entire self-directed IRA as of January 1 of the year the loan was made. His full account balance would then be treated as a taxable distribution, and at 50 he would also face a 10% early withdrawal penalty on top of the ordinary income tax owed, all to fund a $60,000 loan.

Given that his account holds considerably more than $60,000, the potential tax hit from disqualification would have dwarfed any interest income the loan itself might have generated.

Who He Actually Could Lend To From The IRA

Self-directed IRAs can lend money to unrelated third parties, or even to certain family members outside the disqualified persons list, such as siblings or cousins, as long as the loan is properly documented at a fair market interest rate. The restriction isn't on lending itself, it's specifically on lending to the narrow category of relatives and related parties the IRS defines as disqualified.
