Straight line basis is a method used to calculate the depreciation of an asset over its useful life. When an asset is sold, the difference between the sale price and the asset's adjusted basis is known as the taxable gain or loss. The straight line basis affects the calculation of taxable gains or losses upon asset sale in several ways.
Firstly, the straight line basis determines the depreciation expense that is deducted from the asset's value each year. By spreading the cost of the asset evenly over its useful life, the straight line basis ensures a consistent deduction for depreciation in each
accounting period. This depreciation expense reduces the asset's adjusted basis over time.
The adjusted basis of an asset is its original cost, including any improvements or additions, minus the accumulated depreciation. When an asset is sold, the adjusted basis is subtracted from the sale price to determine the taxable gain or loss. If the sale price is higher than the adjusted basis, a taxable gain is realized. Conversely, if the sale price is lower than the adjusted basis, a taxable loss is incurred.
The straight line basis impacts the calculation of taxable gains or losses by affecting the adjusted basis of the asset. As the straight line depreciation expense reduces the adjusted basis each year, it can lower the taxable gain upon sale. This is because a lower adjusted basis results in a smaller difference between the sale price and adjusted basis, leading to a smaller taxable gain.
For example, let's consider a company that purchased a machine for $100,000 with an estimated useful life of 10 years and no salvage value. Using the straight line basis, the company would deduct $10,000 ($100,000 divided by 10) as depreciation expense each year. After five years, the accumulated depreciation would be $50,000 ($10,000 multiplied by 5), and the adjusted basis would be $50,000 ($100,000 minus $50,000).
If the company sells the machine after five years for $60,000, the taxable gain would be calculated as the sale price ($60,000) minus the adjusted basis ($50,000), resulting in a taxable gain of $10,000. However, if the company had used a different depreciation method that resulted in higher depreciation expenses, the adjusted basis would have been lower, potentially reducing the taxable gain further.
Conversely, if the company sells the machine for $40,000 after five years, the taxable loss would be calculated as the sale price ($40,000) minus the adjusted basis ($50,000), resulting in a taxable loss of $10,000. Again, if a different depreciation method had been used, resulting in lower depreciation expenses and a higher adjusted basis, the taxable loss would have been smaller.
In summary, the straight line basis impacts the calculation of taxable gains or losses upon asset sale by influencing the adjusted basis of the asset. By spreading the cost of the asset evenly over its useful life, the straight line basis reduces the adjusted basis over time, potentially reducing taxable gains or increasing taxable losses upon sale.
