Example for depreciation computation
David started using a home office in May 2019. Other relevant data are :
- Basis in house =$300,000.
- Land cost : $30,000.
- Improvements to property : $20,000
- Area of office: 120 square feet
- Area of home is 1,200 square feet.
Adjusted basis of house = $270,000 ($300,000 – $30,000)
Depreciation Factor for the month of May= 1.605% .
That means the total deprecation for house for year 2019 equals: $270,000 x 1.605% = $4333.5
Depreciation deduction for her home office in 2019 would be: Total depreciation x % of business use which comes to $4333.5 x 10% = $433.35
