Seiko's current salary is $106,000. Her marginal tax rate is 32 percent, and she fancies European sports cars. She purchases a new auto each year. Seiko is currently a manager for Idaho Office Supply. Her friend, knowing of her interest in sports cars, tells her about a manager position at the local BMW and Porsche dealer. The new position pays $91,100 per year, but it allows employees to purchase one new car per year at a discount of $24,900. This discount qualifies as a nontaxable fringe benefit. In an effort to keep Seiko as an employee, Idaho Office Supply offers her a \$15,900 raise. Answer the following questions about this analysis. Required: What is the annual after-tax cost to Idaho Office Supply if it provides Seiko with the $15,900 increase in salary? Note: Ignore payroll taxes. b-1. Financially, which offer is better for Seiko on an after-tax basis? b-2. By how much is the offer better for Seiko on an after tax basis? (Assume that Seiko is going to purchase the new car whether she switches jobs or not.) c.
