Final answer:
Jim can include the fire and casualty insurance premiums on his home as part of his home office expense deduction, but not the payment to his housekeeper.
Step-by-step explanation:
Jim can use his fire and casualty insurance premiums on his home as part of his home office expense deduction. However, he cannot include the payment to his housekeeper as an allocable expenditure for the home office expense deduction. The expense must be directly related to the maintenance and upkeep of the office space itself, and the housekeeper's duties are not specific to the office.
