Clem is married and is a skilled carpenter.

Clem’s wife, Wanda, works part-time as a substitute grade school teacher. Determine the amount of Clem’s expenses that are deductible for AGI this year (if any) under the following independent circumstances:

a. Clem is self-employed and this year he incurred $525 in expenses for tools and supplies related to his job. Since neither were covered by a qualified health plan, Wanda paid health insurance premiums of

$3,600 to provide coverage for herself and Clem (not through an exchange).

b. Clem and Wanda own a garage downtown that they rent to a local business for storage.

This year they incurred expenses of $1,250 in utilities and $780 in depreciation.

c. Clem paid self-employment tax of $15,300

(the employer portion is $7,650), and Wanda had $3,000 of Social Security taxes withheld from her pay.

d. Clem paid $45 to rent a safety deposit box to store his coin collection. Clem has collected coins intermittently since he was a boy, and he expects to sell his collection when he retires.
