Final answer:
Clem can deduct a total of $6,355 in expenses for AGI this year.
Step-by-step explanation:
Under the independent circumstances outlined in the question:
a. Clem can deduct $725 as a self-employed carpenter for tools and supplies related to his job. Wanda's health insurance premiums of $6,150 are not deductible for AGI because they were not paid through an exchange.
b. Clem and Wanda can deduct $1,490 in utilities and $1,140 in depreciation for the garage they own and rent out.
c. Clem can deduct the full amount of self-employment tax he paid of $16,600. Wanda's Social Security taxes withheld from her pay are not deductible for AGI.
d. Clem cannot deduct the $85 he paid to rent a safe deposit box for his coin collection because it is a personal expense.
The total amount of Clem's deductible expenses for AGI this year is $6,355 ($725 + $1,490 + $1,140 + $16,600 - $85).
