Depletion (accounting)

Depletion is an accounting concept used most often in mining, timber, petroleum, or other similar industries. The depletion deduction allows an owner or operator to account for the reduction of a product's reserves. Depletion is similar to depreciation in that it is a cost recovery system for accounting and tax reporting. For tax purposes, the two types of depletion are cost depletion and percentage depletion.

According to the IRS Newswire, over 50 percent of oil and gas extraction businesses use cost depletion to figure their depletion deduction.

Businesses can treat two or more separate interests as one property or as separate properties.
