Exercise 46

{Planning} Parley needs a new truck to help him expand Parley's Plumbing Palace. Business has been booming and Parley would like to accelerate his tax deductions as much as possible (ignore §179 expense and bonus depreciation for this problem). On April 1, Parley purchased a new delivery van for $25,000. It is now September 26 and Parley, already in need of another vehicle, has found a deal on buying a truck for $22,000 (all fees included). The dealer tells him if he doesn't buy the truck (Option 1), it will be gone tomorrow. There is an auction (Option 2) scheduled for October 5 where Parley believes he can get a similar truck for $21,500, but there is also a $500 auction fee.
Which option allows Parley to generate more depreciation expense deductions this year (the vehicles are not considered to be luxury autos) Assume the original facts except that the delivery van was placed in service one day earlier on March 31 rather than April 1. Which option generates more depreciation expense
