SF Phоsphates Limited Company (“Phosphates”) seeks review of a Tax Commission order assessing a sales tax deficiency against it on the transfer of electricity to ■ its 98 percent-owned subsidiary, SF Pipeline Limited Company (“Pipeline”). The Tax Commission found that electricity provided by Phosphates to Pipeline was not electricity used in mining and was therefore subject to sales tax. We affirm..
The parties stiрulated before the Commission to the following facts. Phosphates owns and operates a phosphate mine in Vernal, Utah, from which it transports ore to its fertilizer plant in Rock Springs, Wyoming via a pipeline owned and operated by Pipeline, a common carrier. Phosphates owns 98 percent of Pipeline, but the two are separately incorporated. Phosphates furnishеs Pipeline with the electricity used to operate the pipeline from lines that attach beyond the point at which Utah Power meters electricity to Phosphates. Pipeline pays Phosрhates for the electricity it uses at the same rate Utah Power sells electricity to Phosphates. Phosphates has not paid sales tax on the transfer of electricity to Pipeline, clаiming that all electricity shown on its meter is used in mining and is therefore exempt- from sales tax.
The Tax Commission audited Phosphates and assessed sales tax for the period of April, 1992 through December, 1994 on the electricity Phosphates furnished to Pipeline. Phosphates petitioned for redetermination. After a formal hearing, the Tax Commission concluded that the electricity sold by Phosphates to Piрeline is subject to sales tax because Pipeline is a common carrier in the business of transportation, a commercial activity, and therefore section 59-12-103(l)(c) of the Utah Code requirеs Phosphates to collect sales tax.
This case involves the interpretation of statutes defining transactions to which sales tax applies and of Tax Commission rules. The Tax Commission’s constructiоn of the statute presents a question of law, which we review for correctness.

Phosphates argues first that the electricity it provided to Pipeline for the transportation of ore was for use in mining, a noncommercial activity not subject to sales
Phosphates relies upon Tax Commission rule 865-19-35S for its claimed exemption. That rule defines “noncommercial consumption” as “fuel used in: mining or extraction of minerals.” Utah Admin. Code R865-19-35S(B)(1)(1994). Phosphates argues that the electricity provided to Piрeline for the transportation of ore is fuel used in mining, an exempt noncommercial activity.

However, the rule must be construed in a manner consistent with the statute, which specifically includes transportation in the definition 'of commercial activity.
See Sanders Brine Shrimp v. Audit Div.,
“Furthermore, while courts should generally construe taxing statutes favorably to the taxpayer and strictly against the taxing authority, ‘the reverse is true of exemptions.’ ”
Union Pacific R.R. v. Auditing Div.,
■ Phosphates argues that the term “mining” must have one definition for all tax-related purpоses and urges us to adopt the broad definitions of the term contained in Utah Code Ann. §§ 59-2-102(15) and -5-201(3). We decline to do so. The tax code itself assigns different meanings to the term “mining” for different types of taxes.
Compare
Utah Code Ann. § 59-2-102(15) (1992) (defining mining for purposes of the Property Tax Act)
with
Utah Code Ann. § 59-5-201(3) (1992) (defining mining for purposes of the Severance Tax Act). Moreover, neither of the aforementioned broad definitions of mining relate to an exemption. Rather, they
Phosphates maintains next that even if the electricity it transfers to Pipeline is not used in a sales tax-exempt activity, the Tax Commission’s “predominant use rule” applies to exempt the transaction from sales tax. Rule 865-19-35S provides that when “a firm has activities which are commercial and noncommercial and all fuels are furnished at given locations through singlе meters, the predominant use of the fuels shall determine taxable status of the fuels.” Utah Admin. Code R865-19-35S(E) (1994). Phosphates contends that since all the electricity supplied by Utah Power comes through one mеter and Phosphates uses 78 percent of the electricity in exempt mining activity, the predominant use rule applies to exempt sales tax on all electricity supplied through that meter, inсluding the electricity Phosphate supplies to Pipeline.
The Commission maintains that the predominant use rule does not apply because the electricity is not supplied through a “single meter.” It contends that because Pipeline owns a meter at its pumping station that measures the electricity supplied by Phosphates, the electricity is not supplied through a “single meter” and the rule is inaрplicable. This argument is not persuasive. First, the Commission specifically found that Utah Power supplied electricity to Phosphates through a single meter. Furthermore, thé statutory definition of “meter” suppоrts Phosphates’ interpretation that Utah Power supplied electricity through a single “meter.” See Utah Admin. Codé R746-310-1B.7 (defining meter as the “device used to measure the electricity transmitted from an electric utility to a customer”).
Although not specifically mentioned in its decision, the Commission appears to have relied on the fact that Phosphates and Pipeline are distinct legal entities (one a mining оperation, the other a common carrier) in concluding that the two do not constitute a “firm” within the meaning of Rule 865-19-35S, thus precluding the applicability of the predominant use rule. A firm is “ ‘a business unit or enterрrise,’ an ‘unincorporated business’ or a ‘partnership of two or more persons.’ ”
Barton v. Industrial Comm’n,
Phosрhates argues for broader interpretation of the rule. A broader interpretation of the rule, however, could lead to abuse, allowing loosely-related organizations to take advаntage of the rule to avoid paying sales tax on the transfer of electricity for commercial activities. Additionally, we note that Phosphates’ ownership of Pipeline does not exemрt Phosphates from paying sales tax on transactions between the two. Having elected separate corporate forms, Phosphates and Pipeline are bound by the obligations and benefits of those forms.
See Institutional Laundry Inc. v. State Tax Comm’n,
The judgment of the Tax Commission is affirmed.
Notes
. Unless otherwise indicated, all statutory references are to the 1992 code sections in effect during the audit period April 1992 through December 1994.
. In its reply brief. Phosphates argues that it cannot sell or furnish electricity to Pipeline because doing so would bring Phosphates within the definition of a public utility. See Utah Code Ann. §§ 54-2-1(6) & (14). Other than mentioning the statutory definitions, Phosphates fails to provide any support for its contention that "furnishing'' has the same meaning in the Sales Tax Act as it does for the regulation of public utilities.
