Final answer:
The depreciation deduction for Mr. G, who uses 40% of his home for business purposes, would be the full amount of $1,500, assuming this figure correctly represents the allocated business portion.
Step-by-step explanation:
To calculate Mr. G's depreciation deduction with respect to his residence under the regular method of office deduction, we need to determine the allowable depreciation for the business use portion of the residence. The business use area is the basement, which has an area of 800 square feet out of the total 2,000 square feet of the residence. Mr. G can depreciate the cost of the basement over its useful life, which will result in a depreciation deduction.
The formula to calculate the depreciation deduction is:
Depreciation deduction = (Cost of basement / Useful life of basement) * Percentage of business use
In this case, Mr. G incurred a depreciation expense of $1,500 on the basement portion each year. Since the basement is 800 square feet out of the total 2,000 square feet, the percentage of business use is 40% (800 / 2000 = 0.4).
Therefore, the depreciation deduction for Mr. G's residence under the regular method of office deduction is:
Depreciation deduction = ($1,500 / Useful life of basement) * 0.4
