What Is Unrelated Debt Financed Income (UDFI) in a Self-Directed IRA?

The most common case of UDFI occurs when an IRA purchases real estate using a non-recourse loan. 

Here’s how it works:

Example: Let’s say your IRA purchases a property for $100,000. Of that, $40,000 is from IRA funds, and $60,000 comes from a non-recourse loan. The property is now 60% leveraged — meaning 60% of the income generated is not from your IRA’s direct investment but from the borrowed funds.

Since debt is not retirement-plan money, the IRS taxes the portion of income related to that debt. In this example, if the rental property earns $10,000 in net income, then 60% (or $6,000) would be classified as UDFI and subject to UBIT.

UDFI is a critical concept to understand when leveraging assets in your self-directed IRA. The use of leverage can enhance returns, but it may come with tax consequences.
