Question

1. Suppose the tax rate is 30% if taxable income is positive and 0% if taxable income in negative. Calculate the expected tax payable for the following four projects. Note for each project the expected taxable income is $50,000. For each project, also calculate the expected average tax rate (expected total taxes divided by expected taxable income).


a. certain payoff $50,000

b. a 50% chance of $100,000 and 50% of $0

c. a 50% chance of $200,000 and 50% chance of a loss of $100,000

d. a 50% chance of $500,000 and 50% chance of a loss of $400,00


2. Suppose the tax rate is 0% for taxable income less than $0 (again, no tax refunds for losses and no NOL carryback or carryforwards). For positive taxable income up to and including $25,000, the tax rate is 15%; for taxable income greater than $25,000 but less than $50,000, the tax rate is 25%; and for taxable income greater than $50,000, the tax rate is 34%. Calculate the expected tax payable for the following two projects.


a. a 50% chance fo $100,000 and a 50% chance of a loss of $50,000

b. a 50% chance of $75,000 and a 50% chance of a loss of $25,000

Explanation / Answer

1.a. Tax = 50,000*30% = 15,000

b. Tax = 50%*100,000*30% + 0 = 15,000

c. Tax = 50%*200,000*30% + 0 = 30,000

d. Tax = 50%*500,000*30% + 0 = 75,000


2. a. Tax = 50%*(25,000*15%+25,000*25%+50,000*34%) + 0 = 13,500

b. Tax = 50%*(25,000*15%+25,000*25%+25,000*34%) + 0 = 9,250


Hope this helped ! Let me know in case of any queries.
