Title 26 › Subtitle Subtitle A— Income Taxes › Chapter 1— NORMAL TAXES AND SURTAXES › Subchapter I— Natural Resources › Part I— DEDUCTIONS › § 616
You can deduct costs you pay to develop a mine or other natural deposit (but not an oil or gas well) from your taxable income if the ore or mineral has been shown to exist in commercially marketable amounts. Costs to buy or improve property that you normally depreciate under section 167 are not covered here, although any depreciation you take is treated as a development cost for these rules. You may choose, under rules set by the Secretary, to treat development costs as deferred and deduct them little by little as the units of ore or mineral are sold. During the development stage, that choice only applies to the amount by which expenses exceed that year’s net receipts from the mine. Deferred amounts increase the mine’s adjusted basis but are ignored when figuring depletion under section 611. For mines outside the United States, the regular rules above do not apply; those foreign development costs can either be added to basis for computing depletion under section 611 (ignoring section 613) if you elect, or else must be deducted evenly over 10 taxable years starting when paid. See section 59(e) for the 10-year amortization election.
