Title 26 › Subtitle A — Income Taxes › CHAPTER 1 — NORMAL TAXES AND SURTAXES › Subchapter I — Natural Resources › PART I — DEDUCTIONS › § 611
Allows a deduction from taxable income for using up natural resources and for wear and tear on related improvements for mines, oil and gas wells, other natural deposits, and timber. The deduction must be a reasonable amount that fits each situation and follow rules the Secretary sets. "Mines" also covers waste or residue deposits treated as mining under section 613(c). If work shows the amount you can recover is bigger or smaller than you first thought, you must update that estimate (but not the original depletion basis) and use the new estimate for later years. If the property is leased, the deduction is split fairly between owner and renter. A person with a life interest is treated as the owner and gets the deduction. For trusts, split the deduction according to the trust document or by each party’s share of trust income. For estates, divide the deduction between the estate and beneficiaries based on the income each gets. See section 167 for other rules about depreciation of improvements.
