An office building has a depreciable basis of $780,000. For tax purposes, a useful life of 39 years is used, with no salvage value. Under straight-line depreciation, the book value of the property is decreased by $20,000 ($780,000 -r 39) per year. The tax deduction for depreciation, therefore, is $20,000 per year.
