This notice announces the applicable percentage under § 613A of the Internal Revenue Code to be used in determining percentage depletion for marginal proper­ ties for the 2025 calendar year.

Section 613A(c)(6)(C) 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 § 45K(d)(2)(C)) for crude oil for the calendar year preceding the calendar year in which the taxable year

begins. The ref­erence price determined under § 45K(d)(2)(C) for the 2024 calendar year is $74.48. Accordingly, 15% is the applicable percentage under § 613A to be used in determining percentage depletion for marginal properties for the 2025 calendar year.

The following table contains the appli­ cable percentages for marginal production for taxable years beginning in calendar years 1991 through 2025.
