Definition of Depletion

Depletion refers to the allocation of the cost of natural resources (minerals, oil, gas, timber, etc.) over time as they are extracted or used up. It is an accounting method similar to depreciation but specifically applied to natural resources. Unlike depreciation, which pertains to tangible assets like buildings and equipment, depletion directly concerns the gradual consumption of natural resource assets.

Examples

  1. Mining Operations: When a mining company extracts iron ore from its mines, it uses depletion to allocate the cost of the mine over the period the iron ore is extracted.

  2. Oil and Gas Wells: An oil company calculates the cost of drilling an oil well and allocates this cost over the volume of oil extracted using depletion.

  3. Timber Harvesting: A logging company applies depletion to its timber tracts to spread out the cost of forestry over the period the trees are cut down and sold.

Frequently Asked Questions (FAQs)

Q1: How is depletion different from depreciation and amortization?

  • A1: Depletion is specifically for natural resources, while depreciation is used for tangible fixed assets like machinery and buildings, and amortization is for intangible assets such as patents and trademarks.

Q2: How is the depletion amount calculated?

  • A2: There are two main methods to calculate depletion: Cost Depletion and Percentage Depletion. Cost Depletion involves allocating the total cost divided by the total expected quantity to be extracted, while Percentage Depletion involves applying a fixed percentage provided by tax law to the gross income from the resource.

Q3: What is Cost Depletion?

  • A3: Cost Depletion allocates the cost of the resource property over the quantity of resource units expected to be recovered. It reduces the tax basis of the resource property.

Q4: What is Percentage Depletion?

  • A4: Percentage Depletion allows a fixed percentage of the gross income from resource extraction to be claimed as a deduction. It does not need to be linked to the actual cost and may exceed the property’s tax basis.

Q5: Can depletion deductions be claimed for all natural resources?

  • A5: Not all resources qualify for depletion deductions as there are specific IRS guidelines defining which natural resources can be depleted for tax purposes. For example, minerals, oil and gas, and timber often qualify.
  • Depletion Accounting: The process of expensing the cost of natural resources gradually as they are consumed.
  • Wasting Asset: An asset that has a finite life, such as natural resources, which get depleted over time.
