What is the meaning of adjusted basis?

adjusted basis is the original cost basis of a property reduced by certain deductions and increased by certain improvement costs. The original basis determined at the time of acquisition is reduced by the amount of allowable depreciation or depletion allowances taken by the taxpayer, and by the amount of any uncompensated property losses suffered by the taxpayer. It then increases by the cost of capital improvements plus certain carrying costs and assessments. The amount of gain or loss recognized by the taxpayer upon sale of the property is determined by subtracting the adjusted basis on the date of sale from the adjusted sales price. (See basis, capital gain).
