Except as otherwise provided in this section, the allowance for depletion under section 611 with respect to any oil or gas well shall be computed without regard to section 613.

The allowance for depletion under section 611 shall be computed in accordance with section 613 with respect to—

The allowance for depletion under section 611 shall be computed in accordance with section 613 with respect to—

(A) regulated natural gas, and

(B) natural gas sold under a fixed contract,

(2) Natural gas from geopressured brine The allowance for depletion under section 611 shall be computed in accordance with section 613 with respect to any qualified natural gas from geopressured brine, and 10 percent shall be deemed to be specified in subsection (b) of section 613 for purposes of subsection (a) of such section.

For purposes of this subsection—

(A) Natural gas sold under a fixed contract The term “natural gas sold under a fixed contract” means domestic natural gas sold by the producer under a contract, in effect on February 1, 1975, and at all times thereafter before such sale, under which the price for such gas cannot be adjusted to reflect to any extent the increase in liabilities of the seller for tax under this chapter by reason of the repeal of percentage depletion for gas. Price increases after February 1, 1975, shall be presumed to take increases in tax liabilities into account unless the taxpayer demonstrates to the contrary by clear and convincing evidence.

(B) Regulated natural gas The term “regulated natural gas” means domestic natural gas produced and sold by the producer, before July 1, 1976, subject to the jurisdiction of the Federal Power Commission, the price for which has not been adjusted to reflect to any extent the increase in liability of the seller for tax under this chapter by reason of the repeal of percentage depletion for gas. Price increases after February 1, 1975, shall be presumed to take increases in tax liabilities into account unless the taxpayer demonstrates the contrary by clear and convincing evidence.

(C) Qualified natural gas from geopressured brineThe term “qualified natural gas from geopressured brine” means any natural gas— (i) which is determined in accordance with section 503 of the Natural Gas Policy Act of 1978 to be produced from geopressured brine, and (ii) which is produced from any well the drilling of which began after September 30, 1978, and before January 1, 1984.

Except as provided in subsection (d), the allowance for depletion under section 611 shall be computed in accordance with section 613 with respect to—

Except as provided in subsection (d), the allowance for depletion under section 611 shall be computed in accordance with section 613 with respect to—

(A) so much of the taxpayer’s average daily production of domestic crude oil as does not exceed the taxpayer’s depletable oil quantity; and

(B) so much of the taxpayer’s average daily production of domestic natural gas as does not exceed the taxpayer’s depletable natural gas quantity;

For purposes of paragraph (1)—

(A) the taxpayer’s average daily production of domestic crude oil or natural gas for any taxable year, shall be determined by dividing his aggregate production of domestic crude oil or natural gas, as the case may be, during the taxable year by the number of days in such taxable year, and

(B) in the case of a taxpayer holding a partial interest in the production from any property (including an interest held in a partnership) such taxpayer’s production shall be considered to be that amount of such production determined by multiplying the total production of such property by the taxpayer’s percentage participation in the revenues from such property.

For purposes of paragraph (1), the taxpayer’s depletable oil quantity shall be equal to—

(A) In generalFor purposes of paragraph (1), the taxpayer’s depletable oil quantity shall be equal to— (i) the tentative quantity determined under subparagraph (B), reduced (but not below zero) by (ii) except in the case of a taxpayer making an election under paragraph (6)(B), the taxpayer’s average daily marginal production for the taxable year.

(B) Tentative quantity For purposes of subparagraph (A), the tentative quantity is 1,000 barrels.

(4) Daily depletable natural gas quantity For purposes of paragraph (1), the depletable natural gas quantity of any taxpayer for any taxable year shall be equal to 6,000 cubic feet multiplied by the number of barrels of the taxpayer’s depletable oil quantity to which the taxpayer elects to have this paragraph apply. The taxpayer’s depletable oil quantity for any taxable year shall be reduced by the number of barrels with respect to which an election under this paragraph applies. Such election shall be made at such time and in such manner as the Secretary shall by regulations prescribe.

[(5) Repealed. Pub. L. 101–508, title XI, § 11815(a)(1)(C), Nov. 5, 1990, 104 Stat. 1388–557]

Except as provided in subsection (d) and subparagraph (B), the allowance for depletion under section 611 shall be computed in accordance with section 613 with respect to—

(A) In generalExcept as provided in subsection (d) and subparagraph (B), the allowance for depletion under section 611 shall be computed in accordance with section 613 with respect to— (i) so much of the taxpayer’s average daily marginal production of domestic crude oil as does not exceed the taxpayer’s depletable oil quantity (determined without regard to paragraph (3)(A)(ii)), and (ii) so much of the taxpayer’s average daily marginal production of domestic natural gas as does not exceed the taxpayer’s depletable natural gas quantity (determined without regard to paragraph (3)(A)(ii)), and the applicable percentage shall be deemed to be specified in subsection (b) of section 613 for purposes of subsection (a) of that section.

(B) Election to have paragraph apply to pro rata portion of marginal production If the taxpayer elects to have this subparagraph apply for any taxable year, the rules of subparagraph (A) shall apply to the average daily marginal production of domestic crude oil or domestic natural gas of the taxpayer to which paragraph (1) would have applied without regard to this paragraph.

(C) Applicable percentageFor purposes of subparagraph (A), the term “applicable percentage” means the percentage (not greater than 25 percent) equal to the sum of— (i) 15 percent, plus (ii) 1 percentage point for each whole dollar by which $20 exceeds the reference price for crude oil for the calendar year preceding the calendar year in which the taxable year begins. For purposes of this paragraph, the term “reference price” means, with respect to any calendar year, the reference price determined for such calendar year under section 45K(d)(2)(C).

(D) Marginal productionThe term “marginal production” means domestic crude oil or domestic natural gas which is produced during any taxable year from a property which— (i) is a stripper well property for the calendar year in which the taxable year begins, or (ii) is a property substantially all of the production of which during such calendar year is heavy oil.

(E) Stripper well propertyFor purposes of this paragraph, the term “stripper well property” means, with respect to any calendar year, any property with respect to which the amount determined by dividing— (i) the average daily production of domestic crude oil and domestic natural gas from producing wells on such property for such calendar year, by (ii) the number of such wells, is 15 barrel equivalents or less.

(F) Heavy oil For purposes of this paragraph, the term “heavy oil” means domestic crude oil produced from any property if such crude oil had a weighted average gravity of 20 degrees API or less (corrected to 60 degrees Fahrenheit).

(G) Average daily marginal productionFor purposes of this subsection— (i) the taxpayer’s average daily marginal production of domestic crude oil or natural gas for any taxable year shall be determined by dividing the taxpayer’s aggregate marginal production of domestic crude oil or natural gas, as the case may be, during the taxable year by the number of days in such taxable year, and (ii) in the case of a taxpayer holding a partial interest in the production from any property (including any interest held in any partnership), such taxpayer’s production shall be considered to be that amount of such production determined by multiplying the total production of such property by the taxpayer’s percentage participation in the revenues from such property.

If the taxpayer’s average daily production of domestic crude oil exceeds his depletable oil quantity, the allowance under paragraph (1)(A) with respect to oil produced during the taxable year from each property in the United States shall be that amount which bears the same ratio to the amount of depletion which would have been allowable under section 613(a) for all of the taxpayer’s oil produced from such property during the taxable year (computed as if section 613 applied to all of such production at the rate specified in paragraph (1) or (6), as the case may be) as his depletable oil quantity bears to the aggregate number of barrels representing the average daily production of domestic crude oil of the taxpayer for such year.

(A) Production of crude oil in excess of depletable oil quantity If the taxpayer’s average daily production of domestic crude oil exceeds his depletable oil quantity, the allowance under paragraph (1)(A) with respect to oil produced during the taxable year from each property in the United States shall be that amount which bears the same ratio to the amount of depletion which would have been allowable under section 613(a) for all of the taxpayer’s oil produced from such property during the taxable year (computed as if section 613 applied to all of such production at the rate specified in paragraph (1) or (6), as the case may be) as his depletable oil quantity bears to the aggregate number of barrels representing the average daily production of domestic crude oil of the taxpayer for such year.

(B) Production of natural gas in excess of depletable natural gas quantity If the taxpayer’s average daily production of domestic natural gas exceeds his depletable natural gas quantity, the allowance under paragraph (1)(B) with respect to natural gas produced during the taxable year from each property in the United States shall be that amount which bears the same ratio to the amount of depletion which would have been allowable under section 613(a) for all of the taxpayer’s natural gas produced from such property during the taxable year (computed as if section 613 applied to all of such production at the rate specified in paragraph (1) or (6), as the case may be) as the amount of his depletable natural gas quantity in cubic feet bears to the aggregate number of cubic feet representing the average daily production of domestic natural gas of the taxpayer for such year.

(C) Taxable income from the property If both oil and gas are produced from the property during the taxable year, for purposes of subparagraphs (A) and (B) the taxable income from the property, in applying the taxable income limitation in section 613(a), shall be allocated between the oil production and the gas production in proportion to the gross income during the taxable year from each.

(D) Partnerships In the case of a partnership, the depletion allowance shall be computed separately by the partners and not by the partnership. The partnership shall allocate to each partner his proportionate share of the adjusted basis of each partnership oil or gas property. The allocation is to be made as of the later of the date of acquisition of the oil or gas property by the partnership, or January 1, 1975. A partner’s proportionate share of the adjusted basis of partnership property shall be determined in accordance with his interest in partnership capital or income and, in the case of property contributed to the partnership by a partner, section 704(c) (relating to contributed property) shall apply in determining such share. Each partner shall separately keep records of his share of the adjusted basis in each oil and gas property of the partnership, adjust such share of the adjusted basis for any depletion taken on such property, and use such adjusted basis each year in the computation of his cost depletion or in the computation of his gain or loss on the disposition of such property by the partnership. For purposes of section 732 (relating to basis of distributed property other than money), the partnership’s adjusted basis in mineral property shall be an amount equal to the sum of the partners’ adjusted basis in such property as determined under this paragraph.

For purposes of this paragraph—

(A) Component members of controlled group treated as one taxpayer For purposes of this subsection, persons who are members of the same controlled group of corporations shall be treated as one taxpayer.

(B) Aggregation of business entities under common control If 50 percent or more of the beneficial interest in two or more corporations, trusts, or estates is owned by the same or related persons (taking into account only persons who own at least 5 percent of such beneficial interest), the tentative quantity determined under paragraph (3)(B) shall be allocated among all such entities in proportion to the respective production of domestic crude oil during the period in question by such entities.

(C) Allocation among members of the same family In the case of individuals who are members of the same family, the tentative quantity determined under paragraph (3)(B) shall be allocated among such individuals in proportion to the respective production of domestic crude oil during the period in question by such individuals.

(D) Definition and special rulesFor purposes of this paragraph— (i) the term “controlled group of corporations” has the meaning given to such term by section 1563(a), except that section 1563(b)(2) shall not apply and except that “more than 50 percent” shall be substituted for “at least 80 percent” each place it appears in section 1563(a), (ii) a person is a related person to another person if such persons are members of the same controlled group of corporations or if the relationship between such persons would result in a disallowance of losses under section 267 or 707(b), except that for this purpose the family of an individual includes only his spouse and minor children. (iii) the family of an individual includes only his spouse and minor children, and (iv) each 6,000 cubic feet of domestic natural gas shall be treated as 1 barrel of domestic crude oil.

(9) Special rule for fiscal year taxpayers In applying this subsection to a taxable year which is not a calendar year, each portion of such taxable year which occurs during a single calendar year shall be treated as if it were a short taxable year.

(10) Certain production not taken into account In applying this subsection, there shall not be taken into account the production of natural gas with respect to which subsection (b) applies.

In the case of an S corporation, the allowance for depletion with respect to any oil or gas property shall be computed separately by each shareholder.

(A) Computation of depletion allowance at shareholder level In the case of an S corporation, the allowance for depletion with respect to any oil or gas property shall be computed separately by each shareholder.

(B) Allocation of basis The S corporation shall allocate to each shareholder his pro rata share of the adjusted basis of the S corporation in each oil or gas property held by the S corporation. The allocation shall be made as of the later of the date of acquisition of the property by the S corporation, or the first day of the first taxable year of the S corporation to which the Subchapter S Revision Act of 1982 applies. Each shareholder shall separately keep records of his share of the adjusted basis in each oil and gas property of the S corporation, adjust such share of the adjusted basis for any depletion taken on such property, and use such adjusted basis each year in the computation of his cost depletion or in the computation of his gain or loss on the disposition of such property by the S corporation. In the case of any distribution of oil or gas property to its shareholders by the S corporation, the corporation’s adjusted basis in the property shall be an amount equal to the sum of the shareholders’ adjusted bases in such property, as determined under this subparagraph.

The deduction for the taxable year attributable to the application of subsection (c) shall not exceed 65 percent of the taxpayer’s taxable income for the year computed without regard to—

The deduction for the taxable year attributable to the application of subsection (c) shall not exceed 65 percent of the taxpayer’s taxable income for the year computed without regard to—

(A) any depletion on production from an oil or gas property which is subject to the provisions of subsection (c),

(B) any deduction allowable under section 199A,

(C) any net operating loss carryback to the taxable year under section 172,

(D) any capital loss carryback to the taxable year under section 1212, and

Subsection (c) shall not apply in the case of any taxpayer who directly, or through a related person, sells oil or natural gas (excluding bulk sales of such items to commercial or industrial users), or any product derived from oil or natural gas (excluding bulk sales of aviation fuels to the Department of Defense)—

(A) through any retail outlet operated by the taxpayer or a related person, or

(B) to any person— (i) obligated under an agreement or contract with the taxpayer or a related person to use a trademark, trade name, or service mark or name owned by such taxpayer or a related person, in marketing or distributing oil or natural gas or any product derived from oil or natural gas, or (ii) given authority, pursuant to an agreement or contract with the taxpayer or a related person, to occupy any retail outlet owned, leased, or in any way controlled by the taxpayer or a related person.

For purposes of this subsection, a person is a related person with respect to the taxpayer if a significant ownership interest in either the taxpayer or such person is held by the other, or if a third person has a significant ownership interest in both the taxpayer and such person. For purposes of the preceding sentence, the term “significant ownership interest” means—

(A) with respect to any corporation, 5 percent or more in value of the outstanding stock of such corporation,

(B) with respect to a partnership, 5 percent or more interest in the profits or capital of such partnership, and

(C) with respect to an estate or trust, 5 percent or more of the beneficial interests in such estate or trust.

(4) Certain refiners excluded If the taxpayer or one or more related persons engages in the refining of crude oil, subsection (c) shall not apply to the taxpayer for a taxable year if the average daily refinery runs of the taxpayer and such persons for the taxable year exceed 75,000 barrels. For purposes of this paragraph, the average daily refinery runs for any taxable year shall be determined by dividing the aggregate refinery runs for the taxable year by the number of days in the taxable year.

(5) Percentage depletion not allowed for lease bonuses, etc. In the case of any oil or gas property to which subsection (c) applies, for purposes of section 613, the term “gross income from the property” shall not include any lease bonus, advance royalty, or other amount payable without regard to production from property.

For purposes of this section—

(1) Crude oil The term “crude oil” includes a natural gas liquid recovered from a gas well in lease separators or field facilities.

(2) Natural gas The term “natural gas” means any product (other than crude oil) of an oil or gas well if a deduction for depletion is allowable under section 611 with respect to such product.
