Title 26 › Subtitle Subtitle A— Income Taxes › Chapter 1— NORMAL TAXES AND SURTAXES › Subchapter I— Natural Resources › Part I— DEDUCTIONS › § 616
If you develop a mine or other natural deposit (but not an oil or gas well), you can deduct your development costs in the year you pay them, as long as you have already found ores or minerals in amounts worth selling. This does not cover the cost of buying or improving property that gets depreciated. Instead of deducting right away, you can elect to spread the deduction out, taking it bit by bit as you sell the ores or minerals the spending helped produce. Different rules apply to mines outside the United States. For those, you cannot take the regular deduction. You either add the costs to the property's basis for figuring depletion, or deduct them evenly over 10 years. You can also choose to write off these costs over 10 years under section 59(e).
