In 2016, Rashaun (62 years old) retired and planned on immediately receiving distributions (making withdrawals) from his traditional IRA account. The balance of his IRA account is $160,000 (before reducing it for withdrawals/distributions described below). Over the years, Rashaun has contributed $40,000 to the IRA. Of his $40,000 contributions, $30,000 was nondeductible and $10,000 was deductible. Assume Rashaun did not make any contributions to the account in 2016.

a. If Rashaun currently withdraws $20,000 from the IRA, how much tax will he be required to pay on the withdrawal if his marginal tax rate is 25 percent?

b. If Rashaun currently withdraws $70,000 from the IRA, how much tax will he be required to pay on the withdrawal if his marginal tax rate is 28 percent?

c. Using the information provided in part b, complete Form 8606, Part I to report the taxable portion of the $70,000 distribution (withdrawal). Use 2015 forms if 2016 forms are unavailable.
