Example: Corporation A owns 60% of the voting stock of a DISC. Corporation A has a 50% Arizona apportionment ratio and the DISC has a 10% Arizona apportionment ratio for the taxable year. Corporation A and the DISC are not required to file a combined return. Corporation A pays the DISC commissions of $100,000 and deducts this amount on its federal income tax return. The DISC's Arizona taxable income attributable to the commission is $10,000 ($100,000 x 10%). Therefore, Corporation A's addition to Arizona gross income for the DISC commissions is $80,000 ($100,000 - ($10,000 .50)).
Example: Corporation B owns 30% of a DISC that is not a foreign corporation. If the DISC dividends are includible in the Arizona taxable income of Corporation B, the interest charge is not added to Corporation B's Arizona gross income.
