Straight-line depreciation allows an equal portion of the laptop's cost to be claimed in each year over the total depreciation period. If the cost of the computer was $1,000, for example, then $200 a year can be included in the company's total depreciation amount each year for five years.
Best Answer: The roof would be depreciated over 27.5 years as a component of residential real property. The driveway would be depreciated over 15 years. The cost of the roof would be entered on line 19h of form 4562 and cost of the driveway would be entered on line 19e of form 4562. The amount of depreciation being taken on each item in 2008 (the year placed in service) would also go on those same lines.
