Section 40-18-2, Code of Alabama 1975, imposes a tax on every nonresident individual receiving income from property owned or business transacted in Alabama. Also, Section 40-18-14 states that the taxable income of a nonresident individual includes only income from property owned or business transacted in Alabama. An installment note, held by someone who is not in the business of holding installment notes, derived from the sale of investment real property or rental real property by a nonresident individual, would be intangible property that was acquired as income from property held in this state or as a result of business done in this state. “Business income” is defined in Section 40-27-1, Code of Alabama 1975, as income arising from transactions and activities in the regular course of the taxpayer’s trade or business and includes income from tangible and intangible property if the acquisition, management, and disposition of the property constitute integral parts of the taxpayer’s regular trade of business operations. Accordingly, interest that is attributable to the installment note in this situation is taxable for Alabama purposes. Is the interest from the installment note subject to the withholding requirements of Section 40-18-86, Code of Alabama 1975?
