¹ Not applicable if the rate prescribed in subparagraph (2) of this paragraph is applicable.
² The rate prescribed in this subparagraph does not apply except to the extent that alumina and aluminum compounds are extracted therefrom.
³ Applicable only for taxable years beginning before January 1, 1964.
⁴ Applicable only for taxable years beginning after December 31, 1963.
⁵ Applicable only for taxable years beginning before January 1, 1964.
⁶ Not applicable for taxable years beginning after December 31, 1960.
⁷ The 15-percent rate is applicable only to stone used or sold for use by the mine owner or operator as dimension stone or ornamental stone.

(i) Clay, brick and tile--Clay used or sold for use in the manufacture of common brick, drain and roofing tile, sewer pipe, flower pots, and kindred products (other than clay specifically identified as a clay for which a 15 percent rate of percentage allowance is provided).

(ii) Clay, refractory and fire--Clay which has a pyrometric cone equivalent of 19 or higher.

(iii) Pumice--All pumice including pumicite.

(iv) Scoria--Only scoria produced from natural deposits.

Example 1. Pyrite, an iron sulfide, may be sold for either its sulfur content or its iron content, or both. Sulfur is entitled to a percentage depletion deduction based on 23 percent of gross income from the property whereas the percentage depletion deduction for iron is based on 15 percent of such gross income. Therefore, in the case of a taxpayer who sells pyrite for both its sulfur and iron content, 23 percent of his gross income from sulfur plus 15 percent of his gross income from iron would be his maximum allowable percentage depletion deduction. However, this maximum deduction would be subject to the limitation provided for in section 613(a) , i.e., 50 percent of taxable income from the property (computed without allowance for depletion), such taxable income being the overall taxable income resulting from the sale of both minerals contained in the deposit.

Example 2. Oil and gas are produced from a single mineral property of a taxpayer who operates a retail outlet for the sale of oil products within the meaning of section 613A(d)(2). The taxpayer is not entitled to percentage depletion on the gross income attributable to the oil, but is entitled to percentage depletion on the gross income attributable to gas which is regulated gas under section 613A(b)(2)(B). Accordingly, the taxpayer's maximum allowable percentage depletion deduction would be zero percent of gross income from the property with respect to oil, plus 22 percent (see section 613A(b)(1)) of gross income from the property with respect to gas. This maximum deduction would be subject to the limitation provided for in section 613(a), i.e., 50 percent of taxable income from the property (computed without allowance for depletion), such taxable income being the overall taxable income resulting from the sale of both oil and gas. However, in the case of oil or gas production which qualifies for percentage depletion under section 613A(c), see the special allocation rules contained in section 613A(c)(7)(C) and (E) and section 1.613A-4.

(i) The percentage rates set forth in this section are applicable only for taxable years beginning after December 31, 1953, and ending after August 16, 1954; and

(ii) The percentage rates set forth in 26 CFR (1939) 39.23(m)-5 (Regulations 118) are applicable for taxable years beginning before January 1, 1954, or ending before August 17, 1954.

(i) In all cases there shall be excluded in determining the gross income from the property an amount equal to any rents or royalties (which are depletable income to the payee) which are paid or incurred by the taxpayer in respect of the property and are not otherwise excluded from gross income from the property. The following example illustrates this rule:

Example. A leases coal-bearing lands to B on condition that B will annually pay a royalty of 25 cents a ton on coal mined and sold by B. During the year 1956, B mines and sells f.o.b. mine 100,000 tons of coal for $600,000. In computing gross income from the property for the year 1956, B will exclude $25,000 (100,000 tons x $0.25) in computing his allowable percentage depletion deduction. B's allowable percentage depletion deduction (without reference to the limitation based on taxable income from the property) for the year 1956 will be $57,500 (($600,000-$25,000) x 10 percent).

(ii) If bonus payments have been paid in respect of the property in any taxable year or any prior taxable years, there shall be excluded in determining the gross income from the property, an amount equal to that part of such payments which is allocable to the product sold (or otherwise giving rise to gross income) for the taxable year. For purposes of the preceding sentence, bonus payments include payments by the lessee with respect to a production payment which is treated as a bonus under section 636(c). Such a production payment is equally allocable to all mineral from the mineral property burdened thereby. The following examples illustrate the provisions of this subdivision:

Example 1. In 1956, A leases oil bearing lands to B, receiving $200,000 as a bonus and reserving a royalty of one-eighth of the proceeds of all oil produced and sold. It is estimated at the time the lease is entered into that there are 1,000,000 barrels of oil recoverable. In 1956, B produces and sells 100,000 barrels for $240,000. In computing his gross income from the property for the year 1956, B will exclude $30,000 (\1/8\ of $240,000), the royalty paid to A, and $20,000 (100,000 bbls. sold/1,000,000 bbls. estimated to be available x $200,000 bonus), the portion of the bonus allocable to the oil produced and sold during the year. However, in computing B's taxable income under section 63 , the $20,000 attributable to the bonus payment shall not be either excluded or deducted from B's gross income computed under section 61 . (See paragraph (a)(3) of section 1.612-3 .)

Example 2. In 1971, C leases to D oil bearing lands estimated to contain 1,000,000 barrels of oil, reserving a royalty of one-eighth of the proceeds of all oil produced and sold and a $500,000 production payment payable out of 50 percent of the first oil produced and sold attributable to the seven-eighths operating interest. In 1972, D produces and sells 100,000 barrels of oil. In computing his gross income from the property for the year 1972, D will exclude, in addition to the royalty paid to C, $50,000 (100,000 bbls. sold/1,000,000 bbls. estimated to be available x $500,000 treated under section 636(c) as a bonus), the portion of the production payment allocable to the oil produced and sold during the taxable year. However, in computing D's taxable income under section 63, the $50,000 attributable to the retained production payment shall not be either excluded or deducted from D's gross income computed under section 61.

(iii) If advanced royalties have been paid in respect of the property in any taxable year, the amount excluded from gross income from the property of the payor for the current taxable year on account of such payment, shall be an amount equal to the deduction for such taxable year taken on account of such payment pursuant to paragraph (b)(3) of section 1.612-3 .

Example. If B in example (2) in paragraph (b)(4) of section 1.612-3 , elects to deduct in 1956 the $10,000 paid to A in that year, he must exclude the same amount from gross income from the property in 1956; however, if B elects to defer the deduction until 1957 when he mined and sold the mineral, he must exclude the $10,000 from gross income from the property in 1957.
