Final answer:
a. Jessica may deduct $4,312 on her 2021 tax return using the standard mileage method. b. The depreciation deduction for 2021, assuming the actual method was used from the beginning, is $51,607.
Step-by-step explanation:
a. To calculate Jessica's deduction using the standard mileage method, we need to multiply the total miles driven in 2021 by the standard mileage rate for that year. According to Table 6 A-1, the standard mileage rate for 2021 is $0.56 per mile. Therefore, Jessica's deduction for 2021 would be:
Total miles driven in 2021: 7,700
Standard mileage rate: $0.56 per mile
Deduction for 2021: 7,700 miles x $0.56/mile = $4,312
b. If Jessica had used the actual method from the beginning, she would need to calculate the depreciation of the truck for 2021. Since the truck is not subject to luxury auto rules, there are no limitations on the depreciation deduction. The depreciation deduction for 2021 can be calculated using the following formula:
Depreciation deduction = (Cost of the truck / Total expected miles) x Miles driven in 2021
First, we need to determine the total expected miles for the truck. To do this, we subtract the percentage of business use (80%) from the total miles driven:
Total miles driven: 7,200 + 8,200 + 7,700 = 23,100
Total expected miles: Total miles driven - (Total miles driven x Business use)
Total expected miles: 23,100 - (23,100 x 0.8) = 23,100 - 18,480 = 4,620 miles
Now we can calculate the depreciation deduction:
Depreciation deduction = ($31,000 / 4,620 miles) x 7,700 miles
Depreciation deduction = $6.71/mile x 7,700 miles = $51,607
