Answer:
a. Calculate the amount of depreciation for 2017 using financial accounting straight-line depreciation (not the straight-line MACRS election) over the truck's estimated useful life.
depreciation expense per year = $42,000 / 5 = $8,400
depreciation expense for 2017 = $8,400 x 9/12 = $6,300
b. Calculate the amount of depreciation for 2017 using the straight-line depreciation election, using MACRS tables over the minimum number of years with no bonus depreciation or election to expense
using MACRS table, depreciation expense = $42,000 x (20%/2 due to half year) = $4,200
c. Calculate the amount of depreciation for 2017, including bonus depreciation but no election to expense, that Mike could deduct using the MACRS tables
= ($42,000 / 2) + $4,200 = $21,000 + $4,200 = $25,200
d. Assume no income limit on the expense election. Calculate the amount of depreciation for 2017 including bonus depreciation and the election to expense that Mike can deduct
$42,000
