Travis has a 2,400 square foot home. He is a sales representative for a pharmaceutical company and uses one room of his home exclusively for his business. The area of the office is 240 square feet. During the past year, he painted his office and replaced the door at a cost of $500; paid for utilities for his home, $3,000; paid property taxes, $1,500; paid mortgage interest, $3,600; and replaced a door jamb and door for his patio, $600. Depreciation expense on the entire home would be $2,000 for the year. If Travis uses the simplified method for deducting home office expenses, what is correct?
