Internal Revenue Code Section 514 requires debt-financed income to be included in unrelated business taxable income. It was enacted in 1969 for reasons best understood in their historical context. These are known as the Unrelated Debt Financed Income, or UDFI, rules.
Under Internal Revenue Code Section 514 , if an exempt organization owns “debt-financed property,” some portion of each item of gross income from the property, and a like portion of all related deductions, are included in unrelated business taxable income, whether the income is in the form of rent, interest, gain on disposition of the property, or some other character. Property is debt-financed if it is held for the production of income, its use is not substantially related to the organization’s exempt purposes, and there is acquisition indebtedness with respect to the property. The term “acquisition indebtedness” generally includes any liability incurred before, contemporaneously with, or after the acquisition or improvement of the property if it arose because of the acquisition or improvement or if the need for the indebtedness was foreseeable at the time of the acquisition or improvement.
Under Internal Revenue Code Section 514(b)(1), property is “debt-financed property” if it is held to produce income and “acquisition indebtedness” with respect to the property exists at any time during the taxable year (or, in the case of a disposition, at any time during the preceding 12 months). The application of Internal Revenue Code Section § 514 has a wide application. For example, it has been held that securities purchased on margin can be debt-financed property. You need to pay close attention to the UDFI rules when investing with a Self-Directed IRA.
