11 This case is before us on certification from the United States Bankruptcy Court for the District of Utah Central Division. The *169federal bankruptey court has asked us to rule on the following two questions of Utah law:
1. Does Salt Lake County's assessment of property tax on a building omitted from West Side Property Associates' tax assessment notices for 1992 through 1996, when other buildings and the land were assessed, constitute an escaped property assessment as defined by Utah Code Ann. § 59-2-102(8)(@@.[1]
If Salt Lake County's assessment is a valid escaped property assessment, upon what date was the tax incurred.
BACKGROUND
{2 West Side Property Associates ("'West Side") owns and operates the Westgate Business Center ("Westgate property"), an office complex located at the northwest corner of 200 South and 300 West in Salt Lake City, Utah. The property consists of four office buildings and the underlying land.
13 On February 3, 1997, West Side filed a voluntary petition under chapter 11 of the United States Bankruptcy Code. See 11 U.S.C.A. §§ 1-1380 (1998). Thereafter, the bankruptey court fixed August 4, 1997, as the deadline for filing proofs of claims by governmental units.
14 Accordingly, Salt Lake County (the "County") filed a claim against the Westgate property on May 13, 1997, for $51,686.62 in 1996 unpaid taxes, penalties, and interest. The bankruptcy trustees paid this amount to the County on August 15. On November 25, the bankruptey court ruled that this payment fully satisfied the County's May 13 claim.
15 On August 19, 1997, the County conducted a reappraisal of all downtown Salt Lake City properties. This reappraisal included the Westgate property. The County alleges that upon conducting this reappraisal, the appraiser noticed that a building on the Westgate property had not been included on the tax rolls for several years. The appraiser identified this building as the Fine Arts building.
T6 The tax ledgers show that the West-gate property was always assessed as a single property (parcel number 15-01-129-025) that was given an accurate legal description and then a separate tax calculation for "real estate" and one for "buildings." The buildings that comprised the category of "buildings" were not described on the tax ledgers. Similarly, the tax notices sent to West Side showed an accurate legal description for the property and a separate tax calculation for "real estate" and one for "buildings," but no description of the buildings comprising the category of "buildings." Detailed information describing the land and separate buildings is found only in the County's printouts for parcel listings.
T7 On September 2, 1997, the County sent a notice to West Side claiming that the Fine Arts building was "escaped property" and that taxes for the years 1992 through 1996 were owed by November 830. These taxes amounted to $27,142.74. The notice also advised West Side that it could appeal the valuation by October 9, 1997. West Side neither paid nor appealed the tax valuation.
18 On March 6, 1998, the County moved for an allowance of administrative expense claim pursuant to 11 U.S.C.A. § 503(b)(1)(B)G), (C)2 The County based this claim on its escaped property assessment that West Side had not paid. West Side opposed the County's claim, arguing, inter alia, that the property was not escaped property but had been undervalued instead.
{9 Thereafter, pursuant to rule 41 of the Utah Rules of Appellate Procedure, the County moved to have the bankruptey court certify issues of state law to this court. The bankruptcy court decided that before it could rule on the County's administrative claim, it was necessary to determine whether the County's assessment was valid and, if valid, *170when the liability was incurred. Thus, the bankruptcy court certified the above-mentioned two questions to this court.
JURISDICTION
1 10 "The Supreme Court has original jurisdiction to answer questions of state law certified by a court of the United States." Utah Code Ann. § 78-2-2(1) (1996); see also Utah R.App. P. 41.
ANALYSIS
I. CERTIFICATION TO STATE COURT
11 The practice of certifying questions of state law to a state supreme court is a fairly recent device that arose from the judge-made doctrine of abstention, whereby a federal court would abstain until the state court had resolved the state questions. See generally 17A Charlee Alan Wright et al., Federal Practice and Procedure: Jurisdiction 2d §§ 4241-4244, 4246, 4248 (1988). Abstention developed from the doctrine that a federal court "will not 'anticipate a question of constitutional law in advance of the necessity of , deciding it"" Clay v. Sun Ins. Office Ltd., 363 U.S. 207, 211, 80 S.Ct. 1222, 4 LEd.2d 1170 (1960) (quoting Liverpool, N.Y. & Philadelphia Steamship Co. v. Commissioners of Emigration, 118 U.S. 33, 89, 5 S.Ct. 352, 28 L.Ed. 899 (1885); see also Railroad Comm'n v. Pullman Co., 312 U.S. 496, 498, 61 S.Ct. 648, 85 L.Ed. 971 (1941). Therefore, if a federal constitutional question relied on the determination of an uncertain issue of state law, abstention was believed to be the proper course " 'to avoid unnecessary friction in federal-state relations, interference with important state functions, tentative decisions on questions of state law, and premature constitutional adjudication." Lake Carriers' Ass'n v. MacMullan, 406 U.S. 498, 511, 92 S.Ct. 1749, 82 L.Ed.2d 257 (1972) (quoting Harman v. Forssenius, 380 U.S. 528, 534, 85 S.Ct. 1177, 14 LEd.2d 50 (1965)). In Lehman Bros. v. Schein, 416 U.S. 386, 94 S.Ct. 1741, 40 LEd2d 215 (1974), the United States Supreme Court noted that if state certification procedures were available, a federal court should use its discretion in deciding whether to certify an unclear issue of state law even if no constitutional issues were raised. See id. at 390-91, 94 S.Ct. 1741; cf. Thompson v. Magnolia Petroleum Co., 309 U.S. 478, 488-84, 60 S.Ct. 628, 84 L.Ed. 876 (1940) (holding that bankruptey courts should always submit unsettled questions of state property law to state courts). Additionally, the Court emphasized that the use of certification would "save time, energy, and resources and help[ ] build a cooperative judicial federalism." Lehman Bros., 416 U.S. at 391, 94 S.Ct. 1741.
1 12 Consequently, the Tenth Cireuit Local Rules provide for the discretionary use of certification when state law permits. See 10th Cir. R. 27.1(A); see also Hogan v. Oklahoma Dep't of Corrections, No. 98-6127, 1999 WL 84466, at *2, 1999 U.S.App. LEXIS 2896, at *5 (10th Cir. Feb. 22, 1999); Ormsbee Dev. Co. v. Grace, 668 F.2d 1140, 1149 (10th Cir.1982). However, initially, the Utah Constitution did not provide the supreme court with original jurisdiction to answer questions certified from federal courts. See Holden v. N L Indus., Inc., 629 P.2d 428, 429-30 (Utah 1981). Thereafter, portions of the Utah Constitution were repealed and reenacted,3 and section 78-2-24 of the Utah Code was revised to provide the Utah Supreme Court with original jurisdiction to answer questions of state law certified from federal courts.
In formulating the wording of the questions to be certified, a few federal courts ask counsel for both sides to provide assistance. See 17A Wright, supra 111, § 4248, at 176. However, most courts prepare the questions themselves without input from counsel which has, at times, led to the wrong questions being asked. See id. at 177. Therefore, federal courts have adopted the common practice of emphasizing that the particular phrasing of the question should not restrict the state court from reformulating the question as it sees fit. See id. at 178. *171Additionally, most state courts, including Utah, will reformulate the question if necessary regardless of whether the federal court has expressly stated this in the certification. See id.; see also Richardson v. Navistar Int'l Transp. Corp., 2000 UT 65, ¶¶ 8-9, 8 P.3d 263 (noting that question as phrased was ambiguous and therefore giving answer only with respect to specific facts of case at hand); Hirpa v. IHC Hosps., Inc., 948 P.2d 785, 787 n. 1 (Utah 1997) (selecting version of questions that better characterized legal issues to be resolved); Peterson v. Browning, 832 P.2d 1280, 1281 (Utah 1992) (rewording single certified question into two distinct questions). We find it necessary to reformulate the first certified question in the instant case.
1 14 The federal bankruptey court has asked us whether a building "omitted" from a tax assessment notice constitutes escaped property. In wording the question thus, the bankruptey court has made the legal conclusion that the building was omitted property which necessarily makes it escaped property since escaped property is defined as omitted property.5 This would mean that there is no unclear issue of state law for us to address, and therefore, the exercise of certification would be futile. Instead, the proper question to be answered in the case before us is as follows:
If West Side Property Associates' tax assessment notices for 1992 through 1996 gives a separate tax calculation for "real estate" and for "buildings," and "buildings" does not accurately represent the number of buildings on the property, does this constitute undervaluation or escaped property?
We answer the second certified question as presented to us.
II, UNDERVALUATION OR ESCAPED PROPERTY
{ 15 The County Board of Equalization of Salt Lake County argues on appeal that the Fine Arts building is an improvement that was inadvertently omitted from the tax rolls and should thus be assessed as escaped property. West Side counters that the entire Westgate property, as referenced by its legal description and described as "real estate" and "buildings," may have been undervalued due to an inaccurate representation of the improvements designated as "buildings," but not from an omission in the property subject to assessment.
{16 The Utah Property Tax Act (the "Act") provides that "(alll tangible taxable property shall be assessed and taxed at a uniform and equal rate on the basis of its fair market value, as valued on January 1, unless otherwise provided by law." Utah Code Ann. § 59-2-108(1) (Supp.1996). Under the Act, the legislature has delegated to the county assessor the power to assess all property located within the County that is not otherwise required to be assessed by the tax commission. See id. § 59-2-801 (1992). In addition, the assessor is required to list all of the property and maintain an appraisal record that includes the owner of the property, the property identification number, a description of the property, the location of the property, and the full market value of the property. See id. § 59-2-305; Utah Admin. Code R884-24P-37(A). The appraisal record must also separately show the value of the land and the value of any improvements. See Utah Admin. Code R884-24P-37(B).
1 17 In order to collect the property taxes each year, the county treasurer must furnish each taxpayer with a tax notice. See Utah Code Ann. § 59-2-1317(@)(a) (Supp.1996). That notice is required to contain, among other things, the property identification number, the street address, the kind of property assessed, the appraised value of the property, and the amount of tax levied. See id.; Utah Admin. Code R884-24P-86(A).
[ 18 To be sure property taxes are current,
(1) [eJach year the commission shall conduct an investigation throughout each county of the state to determine whether all property subject to taxation is on the assessment rolls, and whether the property is being assessed at fair market value. When, after any investigation, it is found *172that any property which is subject to taxation is not assessed, then the commission shall direct the [assessing authority] to enter the assessment of the escaped property.
(2) If it is found that any property in any county is not being assessed at its fair market value, the commission shall, for the purpose of equalizing the value of property in the state, increase or decrease the valuation of the property in order to enforce the assessment of all property subject to taxation upon the basis of its fair market value, and shall direct the [assessing authority] to correct the value of the property in a manner prescribed by the commission.
Utah Code Ann. § 59-2-1008(1), (2) (1992) (emphasis added). Therefore, the assessor must annually determine if any property has been undervalued or has escaped valuation.
€ 19 Escaped property is defined, in pertinent part, as "any property, whether personal, land, or any improvements to the property, subject to taxation [that] is: (i) inadvertently omitted from the tax rolls." Utah Code Ann. § 59-2-102(7)(a)G) (Supp. 1996). Improvements include the buildings and structures erected on or affixed to the land. See id. § 59-2-102(12). Undervaluation has not been defined by the legislature.
120 The legislature has authorized the original assessing authority, at any time as far back as five years prior to discovery, to assess any property that qualifies as escaped property. See id. § 59-2-309(1) (1992). In addition, the assessors are authorized to increase assessments that have been undervalued. See id. § 59-2-1008(8).
121 When we interpret statutes, we "give effect to the legislative intent, as evidenced by the plain language, in light of the purpose the statute was meant to achieve." State v. Burns, 2000 UT 56, ¶ 25, 4 P.3d 795. Furthermore, it must be remembered that "'statutes imposing taxes and prescribing tax procedures should generally be construed favorably to the taxpayer and strictly against the taxing authority'" County Bd. of Equalization v. Nupetco Assocs., 779 P.2d 1188, 1189 (Utah 1989) (quoting Builders Components Supply Co. v. Cockayne, 22 Utah 2d 172, 175, 450 P.2d 97, 99 (1969)).
122 Land and improvements are recognized as separate constituents, and therefore, each element is subject to separate assessment and taxation. See Utah Code Ann. § 59-2102 (Supp.1996) (defining real estate separately from improvements); see also County Bd. of Equalization v. State Tax Comm'n ex rel. Sunkist Serv. Co., 789 P.2d 291, 298 (Utah 1990). However, if an improvement is shown on the tax assessment notice, reassessment of the improvement is prohibited. See Sunkist, 789 P.2d at 294; Nupetceo, 779 P.2d at 1139 (holding that because entire property was included by means of accurate legal description, acreage mistake constituted undervaluation of assessed property, not escape in assessment); see also Chicago Gravel Co. v. Rosewell, 103 Ill.2d 483, 83 Ill.Dec. 164, 469 N.E.2d 1098, 1100 (1984) (holding that "property which has been assessed, and upon which taxes have been levied and paid in their entirety, even though the assessment through mistake was too low, may not be reassessed in a subsequent year as omitted"); In re National Tube Co., 98 N.E.2d 78, 89 (Ohio Bd. Tax App.1950) (holding that building and structures included in "buildings" valuation without being separately detailed were to be assumed assessed and therefore not omitted). "[Flor an improvement to qualify as an escaped property rather than an underassessed property, the tax assessment notice must not list the improvement." Sunkist, 789 P.2d at 294.
123 Even though Sunkist relied on an earlier escaped property statute, Utah Code Ann. § 59-5-17 (1974), Sunkist is consistent with the statute governing this case, Utah Code Ann. § 59-2-102(7)(a@)@) (Supp.1996), and is therefore still applicable Sunkist recognized that land and improvements were subject to separate assessment and taxation and that any property that had not been assessed was escaped property. See Sunkist, 789 P.2d at 293. Similarly, section 59-2-102(7)(a)(i) provides that any property, whether land or improvements, inadvertently *173omitted from the tax rolls is escaped property.
T24 In the instant case, the assessment notice for West Side included an accurate legal description that encompassed the entire parcel. The assessment specified a value for "real estate" and a separate value for the improvements designated as "buildings." The category of "buildings" did not detail the number of structures included, but provided a value for all of the buildings on the property. As previously stated, "[flor an improvement to qualify as an escaped property rather than an underassessed property, the tax assessment notice must not list the improvement." Sunkist, 789 P.2d at 294. The improvements "buildings" were assessed, and the taxes were levied. West Side relied on this assessment to be correct,. A mistake may have led to an assessment of the improvements that was too low, but "buildings" cannot be reassessed.
125 Because the County's assessment is not a valid escaped property assessment, we need not address the second question certified to us by the bankruptcy court.
CONCLUSION
126 Salt Lake County's error resulted in an undervaluation of the improvements assessed as "buildings," but it did not amount to escaped property.
T 27 Justice DURHAM and Justice DURRANT concur in Associate Chief Justice RUSSON's opinion.. Throughout this opinion, we will use the statutes in effect at the time of the events at issue. The statute defining escaped property in this case is Utah Code Ann. § 59-2-102(7) (Supp.1996) (now codified at Utah Code Ann. § 59-2-102(11) (Supp.2000)).
