Gamboa's Tax Averaging. Gamboa, Incorporated, is a relatively new U.S.based retaler of specialty fruts and vegetables. The frm is vertically integrated with frult and vegetable-sourcing subsidiaries in Central America, and distribution outiets throughout the southeastem and northeastern regions of the United States. Gamboa's two Central American subsidiaries are in Belize and Costa Rica. Maria Gamboa, the daughter of the firm's founder, is being groomed to take over the fim's fnancial management in the near future. Like many firms of Gamboa's size, it has not possessed a very high degree of sophistication in financial manegement simply out of time and cost considerations. Maria, however, has recently finished her MBA and is now attempting to put some specialized knowiedge of U.S. taxation practices to work to save Gamboa money. Her first concern is tax averaging for foreign tax liabilities arising from the two Central American subsidiaries. As shown in the popup window, Costa Rican operations are slightly more proftable than Belice, which is particularly good since Costa Rica is a relatively low-tax country. Costa Fican corporate taxes are a flat 30%, and there are no witholding taxes imposed on dividends paid by foreign firms with operations there. Belize has a higher corporate income tax rate, 40%, and imposes a 10\% with olding tax on all dividends distributed to foreign irwestors. The current U.S, corporate income tax rate is 35%. a. If Maria Gamboa assumes a 70% payout rate from each subsidiary, what are the additional taxes due on foreign-sourced income from Belize and Costa Pica individually? How much in additional U.S. taves would be due if Maria averaged the tax creditsliabilites of the two units? b. Keeping the payout rate from the Belize subsidiary at 70\%, how should Maria change the payout rate of the Costa Rican subsidary in order to most efficiently manage her total foreign tax bil? c. What is the minimum eflective tax rate that Maria can achieve on her foreign-sourced income? If Maria Gamboa assumes a 70% payout rate from each subsidiary, calculate the additional taxes due or excess foreign tax credits on foreign-sourced income from Belize individualy in the Howing table: (Round to the nearest dollar.)
