WEEK 1 HOMEWORK

1) Jack and Jill are married and have three dependent children, and they file a joint 2015 federal

income tax return in March 2015. If they wish to minimize their federal income tax liability and

have adjusted gross income (AGI) of $90,000 and their itemized deductions are $10,000, what is

their taxable income? The 2015 amounts for of the Standard Deduction for married taxpayers

and the exemption amounts can be found at https://www.irs.gov/irb/2014-47_IRB/ar14.html

2) Jean and Jim are married and file a joint return. They expect to have $415,000 of taxable

income in 2015 and are considering whether to purchase a personal residence that would provide

additional tax deductions of $90,000 for mortgage interest and real estate taxes in 2015.

(a) What is their marginal tax rate for making this decision?

(b) What is their tax savings if they acquire the residence?

The 2015 tax rate schedules can be found at https://www.irs.gov/irb/2014-47_IRB/ar14.html

3) Based on the amounts of taxable income below, determine the federal income tax due for the

2015 tax year on each amount assuming the taxpayers are married filing a joint return. Also, for

each amount of taxable income, compute the average tax rate and the marginal tax rate. For your

calculations, use the 2015 Tax Rate Schedules, which can be found at

https://www.irs.gov/irb/2014-47_IRB/ar14.html.

(a) $30,000

(b) $100,000

(c) $375,000

(d) $600,000

4) If a single taxpayer has taxable income of $120,000, how much will he save in taxes if his

CPA shows him that he qualifies for an additional deduction of $4,000?

5) A single taxpayer in the 25% tax bracket has the opportunity to earn additional taxable

income of $10,000 without putting him into a higher tax bracket. How much of the additional

income (after taxes) will the taxpayer get to keep?

6) Assume that a taxpayer has a marginal tax rate of 33%. How much of the income from a

corporate bond earning interest at a 7% rate does the taxpayer keep after taxes are paid on the

interest (i.e., what is the adjusted interest rate after taxes)?

7) If a taxpayer in the 28% tax bracket has the opportunity to invest in a taxable corporate bond

that pays 4% interest or to invest in a tax-exempt municipal bond that pays 3% interest

(assuming that all other elements of the two bonds, e.g., risk, are equal), which investment would

generate the greater after-tax yield?

8) According to the AICPA’s Statements on Standards for Tax Services, what belief must a

CPA have before taking a pro-taxpayer position on a tax return? For assistance in answering this
