Delta Electric Company expects to have an annual taxable income of $500,000 from its residential accounts over the next two years. The company is also bidding on a two‐year wiring service job for a large apartment complex. This ommercial service requires the purchase of a new truck equipped with wire‐ pulling tools at a cost of $50,000. The equipment falls into the MACRS five‐year class and will be retained for future use (instead of being sold) after two years, indicating no gain or loss on this property. The project will bring in additional annual revenue of $200,000, but it is expected to incur additional annual operating costs of $100,000. Compute the marginal tax rates applicable to the project’s operating profits for the next two years.
