June and John decide to form a business. They each plan to contribute $20,000 in exchange for a 50 percent interest in the business. They will then take out a bank loan for $30,000 to cover the balance of their working capital needs. They expect that the business will make a profit of $64,000 in the first year and that it will make a cash distribution of $28,000 each to June and John the first year. Excluding the business income, June, who files as head of household, has $600,000 of other ordinary taxable income. John is married and files a joint return; he and his wife have $240,000 of other ordinary taxable income. Determine how much tax the business will pay and how much additional tax they will personally pay if they form the business as a partnership, S corporation, or C corporation. Consider only income taxes.
