Title 26 › Subtitle A — Income Taxes › CHAPTER 1 — NORMAL TAXES AND SURTAXES › Subchapter B — Computation of Taxable Income › PART II — ITEMS SPECIFICALLY INCLUDED IN GROSS INCOME › § 75
Dealers who buy municipal bonds to sell must lower their taxable income by the amount of bond premium amortization in the ways the rules require. If the dealer keeps inventory and values it by a method other than cost, the cost recorded for bonds sold during the year must be reduced by the amount of premium amortization that would be disallowed under the usual amortizable bond premium rules if municipal bonds were treated like regular bonds. If the dealer does not use inventory, or values inventory at cost, then when a municipal bond is sold the bond’s adjusted basis must be reduced by the amount that the normal basis-adjustment rules would require if municipal bonds were treated like regular bonds. If a bond’s earliest call or maturity is more than 5 years after purchase and the dealer still holds it at year end, do not reduce the cost of securities sold that year; but when that bond is later sold, apply the basis reduction then, even if the dealer values inventory by a method other than cost. Municipal bond: a government-issued obligation whose interest is tax-exempt, except when it was sold within 30 days of purchase or it has an earliest call/maturity more than 5 years after purchase and, when sold, produces proceeds greater than its adjusted basis (interest excluded). Cost of securities sold: opening inventory value plus purchases during the year that belong in inventory, minus closing inventory value.
