2004 Marginal Production Rates
Notice 2004–48
Section 613A(c)(6)(C) of the Internal Revenue Code defines the term “applicable percentage” for purposes of determining percentage depletion for oil and gas
produced from marginal properties. The applicable percentage is the percentage (not greater than 25 percent) equal to the sum of 15 percent, plus one percentage point for each whole dollar by which $20 exceeds the reference price (determined under § 29(d)(2)(C)) for crude oil for the calendar year preceding the calendar year in which the taxable year begins.
Notice 2004–48 Table 1
The reference price determined under § 29(d)(2)(C) for the 2003 calendar year is $27.56.
Table 1 contains the applicable percentages for marginal production for taxable years beginning in calendar years 1991 through 2004.

2004 Section 43 Inflation Adjustment
Notice 2004–49
Section 43(b)(3)(B) of the Internal Revenue Code requires the Secretary to publish an inflation adjustment factor. The enhanced oil recovery credit under
§ 43 for any taxable year is reduced if the “reference price,” determined under § 29(d)(2)(C), for the calendar year preceding the calendar year in which the taxable year begins, is greater than $28 multiplied by the inflation adjustment factor for that year.
The term “inflation adjustment factor” means, with respect to any calendar year, a fraction the numerator of which is the GNP implicit price deflator for the preceding calendar year and the denominator of which is the GNP implicit price deflator for 1990.
Because the reference price for the 2003 calendar year ($27.56) does not exceed $28 multiplied by the inflation adjustment
