Interest paid by U.S. obligors—general (Income Code 1). With specific exceptions, such as portfolio interest (for purposes of chapter 3), you must withhold on interest paid or credited on bonds, debentures, notes, open account indebtedness, governmental obligations, certain deferred payment arrangements (as provided in section 483 of the Internal Revenue Code), or other evidences of indebtedness of U.S. obligors. U.S. obligors include the U.S. Government or its agencies or instrumentalities, any U.S. citizen or resident, any U.S. corporation, and any U.S. partnership. If, in a sale of a corporation's property, payment of the bonds or other obligations of the corporation is assumed by the buyer, that buyer, whether an individual, partnership, or corporation, must deduct and withhold the taxes that would be required to be withheld by the selling corporation as if there had been no sale or transfer. Also, if interest coupons are in default, the tax must be withheld on the gross amount of interest whether or not the payment is a return of capital or the payment of income. A resident alien paying interest on a margin account maintained with a foreign brokerage firm must withhold from the interest whether the interest is paid directly or constructively. Interest on bonds of a U.S. corporation paid to a foreign corporation not engaged in a trade or business in the United States is subject to withholding even if the interest is guaranteed by a foreign corporation. Domestic corporations must withhold on interest credited to foreign subsidiaries or foreign parents. For withholding under chapter 4 on the interest payments described in this section, see the definition of withholdable payments in Regulations section 1.1473-1(a).
