Title 26 › Subtitle Subtitle A— - Income Taxes › Chapter CHAPTER 1— - NORMAL TAXES AND SURTAXES › Subchapter Subchapter P— - Capital Gains and Losses › Part PART V— - SPECIAL RULES FOR BONDS AND OTHER DEBT INSTRUMENTS › Subpart Subpart B— - Market Discount on Bonds › § 1277
You can only deduct interest you pay to buy or hold a bond with market discount if that interest is more than the part of the market discount that applies to the days you owned the bond (use the rules in section 1276(b) to figure that part). If you have net interest income for a year and you make the election allowed by the law, the interest you could not deduct is figured as of the end of the prior year and does not include amounts already counted. The interest you couldn’t deduct becomes deductible when you sell or dispose of the bond. If the transfer is a nonrecognition deal, you can deduct only up to the gain you recognize, and any leftover disallowed interest follows the property or the transferee under section 1276(c). Net direct interest expense: the extra interest you paid in a year on debt used to buy or hold the bond, after subtracting interest from the bond. Net interest income: the excess of the amount figured under subsection (c)(2) over the amount under subsection (c)(1). Disallowed interest expense: the total interest amount not allowed under the main rule.
