that the transfer of overriding royalties to the trust was a disposal of property under § 1254 of the Internal Revenue Code. Section 1254 requires taxpayers who dispose of “oil, gas, or geothermal property” to recognize a gain (i.e., ordinary income) for “the aggregate amount of expenditures after December 31, 1975, which are allocable to such property and which have been deducted as intangible drilling and development costs under § 263(c) by the taxpayer or any other person....”
HOMC petitioned the Tax Court for' rede-termination of the deficiency. The parties stipulated to the facts of the case, and the only question was whether the overriding royalty interests are “oil, gas, or geothermal property.” The Tax Court held that overriding royalty interests are not “oil, gas, or geothermal property.” HOMC, therefore, did not recapture any of the IDCs. The Commissioner appeals.
II.
We review Tax Court decisions under the same standard used for civil actions decided by a federal district court. See 26 U.S.C. § 7482(a). Because the parties stipulated to the facts of this case, we need not examine the Tax Court’s factual determinations. We review the Tax Court’s conclusions of law de novo. See Dresser Indus. v. Comm’r., 911 F.2d 1128, 1132 (5th Cir.1990).
The recapture provision in § 1254(a)(1) applies only to “oil, gas, or geothermal property.”2 To qualify as “oil, gas, or geothermal property,” the overriding royalty interests must meet two requirements under § 1254(a)(3): (1) the royalty interests must fall within the definition of “property” in Code § 614; and (2) the royalty interests must be property to which the IDCs “are properly chargeable.”3
Code § 614 defines “property” as “each separate interest owned by the taxpayer in each mineral deposit in each separate tract or parcel of land.” The Treasury Regulation interpreting this provision states that the term “interest” includes, among other things, overriding royalties. See Treas. Reg. § 1.1614-l(a). The overriding royalty interests at issue in this case fit comfortably within the definition of “property” in § 614, thus meeting the first requirement of “oil, gas, or geothermal property.”
To meet the second requirement of “oil, gas, or geothermal property,” the royalty interests must be property to which the IDCs “are properly chargeable.” The Tax Court concluded that the overriding royalties are not “oil, gas, or geothermal property” because IDCs “are properly chargeable” only against working interests and royalties are nonworking interests. The Commissioner concedes that IDCs are properly chargeable only against working interests, that overriding royalties are nonworking interests, and that HOMC retained 100 percent of the working interests in the oil and gas leases. On the other hand, HOMC admits that the overriding royalties were part of the working interest when the IDCs were deducted (i.e., before carve-out and disposition of the overriding royalties). The only question, therefore, is whether the Tax Court correctly concluded that a property interest must be a working inter
