Dave is a medical device distributor in Nevada and runs his business as a sole proprietor. He therefore pays taxes on his business income as part of his individual income tax filing. Currently his effective tax rate is 37.9% (35% federal income tax rate plus 2.9% Medicare tax rate ââ¬" there is no state income tax in Nevada which is why he moved there from California). He has recently been made aware of a new technology that can be used during surgery that more effectively controls blood loss. Deployment of this technology would require purchasing additional equipment and employing a couple of technicians to use the equipment at local hospitals. He is seeking your advice on whether he should adopt this technology from a financial perspective. The initial investment in the equipment would be $900,000. The machine would operate for eight years, after which the machine would be worthless and Dave is expecting to retire. In each of those eight years, he expects to generate revenue of $900,000 and have an operating margin of 19% (employee expenses and materials would run 81% per year). He would depreciate the machine for tax purposes using straight-line depreciation over the eight years. There would also be an initial investment in working capital of $135,000 which would be fully recovered at the end of the eighth year.
