Charlie Corporation acquired 100% of Delta Corporation common stock on July 1 of the current tax year. Prior to the acquisition, Delta supplied Charlie with about 50% of the raw materials and other components used in producing its plastic toys. Delta will continue to be Charlie’s major supplier as well as a supplier to other toy makers. Both corporations have been profitable for years and expect to be profitable after the acquisition. Charlie’s CEO asks you if the two corporations, filing a single consolidated tax return would be less costly (in terms of both taxes paid and filing fees) than their filing two separate tax returns. How do you respond to this inquiry?
