Summary
It stops people from deducting interest on loans paid with tax-exempt bonds when the property financed is not used the way the tax rules require. If a home bought with a tax-free mortgage is not the borrower’s main home for a continuous period of at least 1 year, interest that accrues during that time can’t be deducted unless the IRS finds undue hardship. Similar rules deny interest deductions when rental projects, small-issue bonds, exempt facility bonds, or bonds for 501(c)(3) projects lose the required use or ownership conditions, or when part of a 501(c)(3) building is used by a non-501(c)(3) business. Payments that are not called interest are treated like interest up to the amount of interest accrued. If only part of a facility is used improperly, only the share of interest for that part is disallowed. The Treasury Secretary may write rules to carry out these limits. It defines key words and some special cases. One-line meanings: bond = any obligation; governmental unit = state or local government (not the U.S. or its agencies); net proceeds = issue proceeds minus required reserves; 501(c)(3) organization = the tax-exempt charity described in section 501(c)(3); tax-exempt bond = a bond whose interest is excluded from gross income; property owned “on behalf of” a government counts as government-owned. A “qualified scholarship funding bond” is a nonprofit corporation’s bond used to buy student loans under the Higher Education Act at a state’s request; special transfer and ownership conditions let such bonds keep tax-exempt status (including transfer of assets to a non-tax-exempt transferee that assumes the debt, holders of senior stock, board independence rules with at least 80% independent members, a 10-year redemption limit for senior stock, and IRS consent needed to revoke the election). Bonds for qualified volunteer fire departments are treated as state or local bonds if 95 percent or more of net proceeds pay for a firehouse or firetruck; those bonds are not private activity bonds except for two narrow code sections.
