Machine Corp. elected subchapter S status (qualified sub-S election) Chad invested $100. Bob then loaned Machine Corp. $50,000, interest free. Machine borrowed 2,450,000 from the bank and purchased the machine. Machine Corp. pays the bank 245,000 per year principle plus interest. Machine Corp. then rents the machine to Bob for 600,000 per year. Machines of that type should rent for 275,000 to 300,000 per year.

Because of rapid write-offs under MACRS, Chad does not anticipate making a profit until 2021.

Income 600,000

Interest to bank 75,000
