- depletion
- An emptying, exhausting or wasting of assets. A reduction during taxable year of oil, gas or other mineral deposits or reserves (i.e., wasting assets) as a result of production. The process by which the cost or other basis of a natural resource (e.g., an oil and gas interest) is recovered upon extraction and sale of the resource@ depletion allowanceThe tax laws allow a depletion allowance (deduction) to owners of oil, gas, mineral, and timber resources as such are exhausted. The two ways to determine the depletion allowance are the cost and percentage (or statutory) methods. Under the cost method, each unit of production sold is assigned a portion of the cost or other basis of the interest. This is determined by dividing the cost or other basis by the total units expected to be recovered. I.R.C. No. 611. Under the percentage (or statutory) method the tax law provides a special percentage factor for different types of minerals and other natural resources. Such depletion is based on a percentage of the estimated gross income to be earned during the period from a natural resource, without reference to the cost of the resource. This percentage is multiplied by the gross income from the interest to arrive at the depletion allowance. I.R.C. No.No. 613 and 613A.See also amortizationSee depletion@ depletion deductionSee depletion@
