OPINION
¶ 1 This appeal arises out of cross-motions for summary judgment on whether the Arizona Department of Revenue (the “Department”) correctly valued property owned by Questar Southern Trails Pipeline Co. (“Taxpayer”) for the 2004 and 2005 tax years. Finding no genuine issue of material fact or error of law, we affirm the grant of summary judgment to the Department. In addition, we affirm the tax court’s award of interest on the judgment.
FACTS AND PROCEDURAL HISTORY
¶2 Taxpayer is a Utah corporation and operates a pipeline in Arizona. It owns legal and/or equitable title to property in Mohave County, Coconino County, Navajo County and Apache County.
¶ 3 Applying the property valuation formula in Arizona Revised Statutes (“A.R.S.”) section 42-14204 (2006),
¶ 4 The Department appealed the SBOE’s valuation to the tax court and Taxpayer likewise appealed the calculation pursuant to A.R.S. §§ 42-16203 and 42-16207 (2006),
¶5 The Department moved for summary judgment on the basis that it had properly applied A.R.S. § 42-14204. Taxpayer filed a cross-motion for partial summary judgment claiming that the Department should have accounted for external obsolescence in determining the value of the property. When the Department disputed the point, Taxpayer submitted an appraisal report with its reply. The tax court granted summary judgment to the Department, upheld its valuations and declined to strike Taxpayer’s exhibit.
¶ 6 On January 25, 2006, the Department lodged a judgment with the tax court. The parties then litigated Taxpayer’s objection to the judgment term requiring it to pay interest on the reinstated full cash value for the 2004 tax year from the date of underpayment.
DISCUSSION
I. As a Matter of Law, the Department Correctly Valued Taxpayer’s Property.
¶ 7 We review de novo the tax court’s grant of summary judgment. Wilderness World, Inc. v. Dep’t of Revenue,
A. The Formula in A.R.S. § 42-14204 Provides the Exclusive Method of Valuation.
¶8 Under Article 9, Section 11, of the Arizona Constitution, the legislature prescribes “the manner, method and mode of assessing, equalizing and levying taxes in the State of Arizona.” The legislature taxes property based upon full cash value and it provided in former A.R.S. § 42-11001(5) (2003):
“Full cash value” for property tax purposes means the value determined as prescribed by statute. If no statutory method is prescribed, full cash value is synonymous with market value which means the estimate of value that is derived annually by using standard appraisal methods and techniques. Full cash value is the basis for assessing, fixing, determining and levying secondary property taxes.
(Emphasis added.)
¶ 9 Title 42, Article 5, of the Arizona Revised Statutes provides the method for valuing pipeline property. The statutes require the Department to determine the value of property owned by each pipeline operating within state borders. AR.S. §§ 42-14201 to -14204. The Department begins the process by mailing all pipeline companies an annual property tax reporting form. A.R.S. § 42-14202. Each company must submit the completed form to the Department on or before April 1 of the valuation year. A.R.S. § 42-14202(A). Pipeline companies must report the cost of all their property as well as income and other information. A.R.S. §§ 42-14202, -14204.
¶ 10 In A.R.S. § 42-14204(F)(l), the legislature directs the Department to determine the 'base value of the pipeline, which is “the final full cash value of the system plant in service.” A.R.S. § 42-14204(H)(3). The De
¶ 11 The Department used the information from Taxpayer to determine its property value for the 2004 and 2005 tax years, including both the original and the revised data. Taxpayer does not challenge the accuracy of the Department’s calculation of value pursuant to the statutory formula. Instead, it asks the Department to also factor in obsolescence using standard appraisal methods.
¶ 12 “Obsolescence, which is a form of depreciation, is defined as a loss of value and is classified as either functional or economic.” Inland Steel Co. v. State Bd. of Tax Comm’rs,
¶ 13 In Arizona Department of Revenue v. Trico Electric Cooperative,
¶ 14 This case parallels Trico. Like the Trico taxpayer, defendant Taxpayer is contesting the value derived from the statutory formula specifically enacted for a species of centrally valued property. Both this taxpayer and the Trico taxpayer complained that the Department had failed to account for obsolescence and had not used standard appraisal methods. As in Trico, the result here must be that the statutory formula is the exclusive method for calculating full cash value.
¶ 15 In an effort to distinguish Trico, Taxpayer claims that Trico did not involve a taxpayer claiming that its property value exceeded market value. Taxpayer argues Trico involved a claim that a formula valued the property of for-profit (or investor-owned) utilities more favorably than non-profit (or cooperative-owned) utilities. A close reading of Trico, however, reveals that the taxpayer raised two arguments: (1) the Department overvalued the property by failing to account for obsolescence and (2) equitable considerations required a different result because other utilities received more favorable values.
¶ 16 Taxpayer also relies on Business Realty of Arizona, Inc. v. Maricopa County,
¶ 17 Because the statutory valuation plainly provides the method of valuation for pipelines, we agree with the tax court’s ruling that the Department did not need to use obsolescence in its valuation process.
B. The Legislative History of A.R.S. § 42-14204 Supports the Tax Court’s Ruling.
¶ 18 Taxpayer contends that the legislative history of A.R.S. § 42-14204 supports consideration of obsolescence. We conclude the opposite is true.
¶ 19 Prior to enactment of the statutory formula in 1980, the Department valued pipelines using standard appraisal methods. Trico,
¶ 20 Taxpayer contends that the valuation arrived at cannot exceed market value, which it insists is the ease here. It points out that in 2006 the legislature amended former A.R.S. § 42-11001(5) to redefine full cash value:
6. “Full cash value” for property tax purposes means the value determined as prescribed by statute. If no statutory method is prescribed, full cash value is synonymous with market value which means the estimate of value that is derived annually by using standard appraisal methods and techniques.... Full cash value shall not be greater than market value regardless of the method prescribed to determine value for property tax purposes.
A.R.S. § 42-11001(6) (Supp.2006); 2006 Ariz. Sess. Laws, ch. 143, § 2 (emphasis supplied for new text).
¶ 21 Even assuming that Taxpayer’s assertion about the property’s valuation exceeding market value is correct,
¶22 Moreover, we cannot agree that this new statute is a clarification or provides persuasive evidence that market value has always been a consideration when applying statutory formulas. In bill form, the provision stated that it modifies the definition of full cash value. See Committee on Ways and Means, House Bill Summary of H.B. 2821, 47th Leg., 2d Reg. Sess., at 1 (Ariz. April 12, 2006). Additionally, the legislative proposal in 2006 that S.B. 1543 add a depreciation provision to A.R.S. § 42-14204 shows that the prior version did not include one. Thus, the legislative history supports the tax court’s ruling.
C. A.R.S. § 42-14003 Does Not Support Taxpayer’s Argument.
¶23 Taxpayer nevertheless contends that A.R.S. § 42-14003(A) (2006)
In determining valuation under this chapter the department shall consider all addi*582 tional information including information that is presented in an appeal and information that is otherwise available.
¶ 24 In taxpayer’s view, obsolescence constitutes additional information for the Department to consider. We “seek to harmonize related statutes ... and ‘aim to achieve consistency among them’ within the context of the overall statutory scheme.” State v. Fell,
¶25 When the legislature wants the Department to consider obsolescence, it has provided express instructions. For example, A.R.S. § 42-14156(A)(4) (2006) provides that an owner of electric generation facilities “may submit documentation showing the need for, and the department shall consider, an additional adjustment to recognize obsolescence using standard appraisal methods and techniques.” Similarly, A.R.S. § 42-14254(B)(4) (2006) states that the Department shall “[ajllow additional obsolescence if supported by market evidence” in valuing flight property. The omission of an obsolescence provision from A.R.S. § 42-14204 and its inclusion in other statutes indicates that the legislature did not intend it to be applied in A.R.S. § 42-14204.
¶ 26 Moreover, it is fundamental that the terms of a specific valuation statute like A.R.S. § 42-14204 control over general statutes like A.R.S. § 42-14003. See Ruth Fisher Elementary Sch. Dist. v. Buckeye Union High Sch. Dist.,
D. Taxpayer Has Waived the Uniformity Argument.
¶ 27 Taxpayer alternatively argues that the tax court’s decision violates uniformity principles. Taxpayer, however, did not raise this issue in the tax court, so we decline to consider it. See Ness v. W. Sec. Life Ins. Co.,
II. Taxpayer Must Pay Interest for 2004 Taxes Starting from the Date of Underpayment.
¶ 28 Taxpayer also challenges the tax court’s decision to award interest starting from the date of underpayment. This argument raises statutory construction issues, which we review de novo. Canon,
¶ 29 Arizona Revised Statutes § 42-16214 provides:
A. If judgment is awarded to a taxpayer who paid the taxes to the county treasurer:
3. Interest at the legal rate on the overpayment or underpayment is payable from the date of overpayment or underpayment. For the purpose of computing interest under the judgment, if the tax was paid in installments, a pro rata share of the total overpayment or underpayment is considered to be attributable to each installment.
¶ 31 Prior to 1996, A.R.S. § 42-16214, along with §§ 42-16212 and -16213, were embodied in A.R.S. § 42-178. See 1996 Ariz. Sess. Laws, ch. 166, § 4, effective July 20, 1996. That statute was titled “Hearing of appeal; judgment; enforcement; correction of assessment roll.” The specific predecessor provisions of A.R.S. § 42-16214 were A.R.S. § 42-178(F)(l)-(3) and (G). Id. Former A.R.S. § 42-178(F)(3) dealt with the consequences of judgments in favor of and against a taxpayer, providing that interest on the “overpayment or underpayment shall be payable from the date of overpayment or underpayment.” Id.
¶32 Meanwhile, former A.R.S. § 42-178(D)(3) provided that a court finding of insufficient valuation created a judgment that was a lien upon the real and personal property of the appellant as though “the assessment had originally been in the amount of the judgment.” Because the legislature intended “solely to recodify the existing statute law of taxation” in Arizona without changing its interpretation or construction, the judgment here reverted to the date of assessment and interest is payable from the date of underpayment. 1997 Ariz. Sess. Laws, ch. 150, § 175(A), (C).
¶ 33 Trico illustrates this point. Applying the predecessor statute A.R.S. § 42-178(E), the Arizona Supreme Court held that interest was due on the taxpayer’s underpayment of taxes from the date of underpayment. Trico,
CONCLUSION
¶ 34 We affirm the tax court’s judgment in all respects. In addition, we deny Taxpayer’s requests for costs and attorneys’ fees incurred during this appeal.
