delivered the opinion for a unanimous Court.
In this case, we decide whether Texas Tax Code sections 11.43 and 25.21 require an appraisal district and chief appraiser to back-appraise in the current year property erroneously exempted in prior years. We further decide whether chapters 41 and 42 of the Tax Code permit a taxing unit to challenge the appraisal district’s and chief appraiser’s failure to fulfill that duty. The trial court granted summary judgment for Respondents, the taxpayer and appraisal district, concluding that limitations or lack of standing barred Petitioners, the taxing units, from challenging prior years’ appraisals. The court of appeals affirmed the summary judgment for the taxpayer.
In the mid-1950s, Atascosa Hospital Association (AHA), a nonprofit corporation, bought land and built Mercy Hospital on it. For nearly thirty years, a charitable society operated Mercy. In the 1980s, for-profit organizations assumed responsibility for operating the hospital. One of these organizations, Tri City Community Hospital, currently leases the hospital buildings and equipment. AHA requested a tax exemption for the land, buildings, and equipment, which the Atascosa County Appraisal District granted.
In 1995, Atascosa County and Jourdan-ton Independent School District filed a challenge petition under Tax Code § 41.03 with the Atascosa County Review Board, requesting it to find that the property was improperly granted tax-exempt status for 1990-1995. The County and School District also requested that the Review Board compel the chief appraiser to add the property’s reappraisal to the 1995 tax rolls.
AHA moved for summary judgment. Without reaching the merits of the prior years’ exemption, the trial court granted summary judgment for both AHA and the Appraisal District. The trial court determined that the relief requested by the County and School District for 1990-1994 was barred under the Tax Code by limitations or lack of standing. The trial court further concluded that the Review Board’s revocation of the 1995 exemption mooted any issues regarding that year.
The court of appeals affirmed summary judgment for AHA, but reversed the summary judgment for the Appraisal District because the District had not filed its own motion for summary judgment.
The County and School District petitioned this Court for review, asking us to reverse and remand this case to the trial court so that it can address the merits of the exemptions. (The Appraisal District has not petitioned for review of the court of appeals’ judgment reversing the summary judgment in its favor.) We granted their petition to review the court of appeals’ construction of the Tax Code.
The County and School District first argue that the Appraisal District and chief appraiser must back-appraise and assess taxes on property erroneously exempted for the past five years. We agree. The Texas Constitution creates the obligation to appraise and assess property for purposes of taxation, and provides that all property must be equally and uniformly taxed. See Tex. Const, art. VIII, § 11 (“[A]ll lands and other property not rendered for taxation by the owner thereof shall be assessed at its fair value by the proper officer.”); Tex. Const, art. VIII, § 1(a) (“Taxation shall be equal and uniform.”). The Legislature codified this obligation to appraise and assess property in the Tax Code. The Tax Code creates appraisal districts and requires each district to appraise property for the ad valorem taxing units within the district. See Tex Tax Code § 6.01. To discharge this duty, appraisal districts must establish appraisal offices and retain chief appraisers. See Tex. Tax Code § 6.05. The Tax Code also establishes an appraisal review board for each district, which is charged with ensuring that property is properly appraised. See Tex. Tax Code §§ 6.41,41.01. Tax Code § 11.43(i) mandates that the chief appraiser back-appraise erroneously exempted property:
If the chief appraiser discovers that an exemption that is not required to be claimed annually has been erroneously allowed in any one of the five preceding years, the chief appraiser shall add the property or appraised value that was erroneously exempted for each year to the appraisal roll as provided by Section 25.21 of this code for other property that escapes taxation.
See also McPhail v. Tax Collector of Van Zandt County,
The Tax Code also establishes a procedure for the appraisal and back-appraisal of property. Subject to limited exceptions, the chief appraiser must appraise all taxable property at market value as of January 1 each year, and must determine whether exemptions should be granted based on the claimant’s eligibility on that date. See Tex. Tax Code §§ 11.42, 11.43, 23.01. Once property is appraised and an exemption denied, the chief appraiser lists all taxable property and its appraised value. See Tex. Tax Code § 25.01. The chief appraiser’s listing of all taxable property in the district and its appraisal value constitutes the appraisal records. See id. The chief appraiser submits the appraisal records to the review board, which reviews the records and hears challenges. See Tex. Tax Code §§ 41.01-03. When approved by the review board, these records become the appraisal district’s tax roll. See Tex. Tax Code § 25.24.
Tax Code § 25.21 mandates the procedure for back-appraising property:
(a) If the chief appraiser discovers that real property was omitted from an appraisal roll in any one of the five preceding years ..., he shall appraise the property as of January 1 of each year that it was omitted and enter the property and its appraised value in the appraisal records.
(b) The entry shall show that the appraisal is for property that was omitted from an appraisal roll in a prior year and shall indicate the year and the appraised value for each year.
Thus, under section 25.21, the omitted property is added to the current year’s appraisal records, and the current appraisal can include an appraisal for each year the property was omitted from the appraisal records for up to the five preceding years. Tex. Tax Code § 25.21; see id. § 11.43(i) (back-appraisal follows the procedure in section 25.21); 1 Tex. Tax Rep. (CCH) ¶ 20-621 (1999) (“The chief appraiser must enter the property and its appraised value in the appraisal records, showing that the appraisal is for property that escaped taxation in a prior year. The entry must indicate the years the property escaped taxation and the appraised value for each year.”).
The court of appeals held, however, that sections 11.43(i) and 25.21 permit back-appraisal only for a limited category of erroneously granted exemptions.
When interpreting a statute, we “consider the entire act, its nature and object, and the consequences that would follow from each construction.”
Sharp v. House of Lloyd, Inc.,
We next address who has standing to challenge the chief appraiser’s refusal to back-appraise property. In affirming the trial court's ruling that the County and School District lacked standing, the court of appeals concluded that adding improperly exempted, property to the current tax rolls is within the exclusive province of the chief appraiser.
Chapters 41 and 42 of the Tax Code allow a taxing unit to challenge appraisal district decisions that affect appraisal records. A taxing unit may file a challenge petition with the appraisal review board. See Tex. Tax Code § 41.04. Among other things, the taxing unit may challenge ‘an exclusion of property from the appraisal records” or “a grant in whole or in part of a partial exemption.” Tex Tax Code § 41.03(2), (3). The review board then schedules a hearing and issues a written order. See Tex. Tax Code §§ 41.05-.07. A taxing unit may appeal this order to the district court for trial de novo. See Tex. Tax Code § 42.23.
One of the appraisal district’s and chief appraiser’s obligations is to back-appraise property that was improperly exempted up to five years ago. See Tex. Tax Code §§ 11.43(i), 25.21. A back-appraisal must be included in the appraisal roll for the current year. See Tex Tax Code §§ 11.43(1), 25.21. As taxing units have standing to challenge appraisal decisions through the chapter 41 challenge petition process, and the decision to omit a back-appraisal from the current tax rol is an appraisal decision, taxing units have standing to challenge a refusal to back-appraise. We see nothing in the Tax Code that indicates otherwise. Moreover, reading sections 11.43 and 25.21 to prevent taxing units from bringing a challenge, and thereby alowing only the chief appraiser to discover improperly granted exemptions, would eviscerate the purpose of the section 41.04 challenge petition process.
As a practical matter, holding that taxing units do not have standing to chalenge an appraisal district’s failure to back-appraise would mean no one could challenge the chief appraiser’s acts. Taxing units would be unable to colect duly owed revenue, and a windfal would result for property owners who wrongfully claim an exemption. The court of appeals noted that interpreting the Tax Code to permit anyone other than the chief appraiser to discover erroneously granted exemptions would disturb the Tax Code’s allocation of power.
The court of appeals also concluded that the County and School District were barred by limitations because they did not challenge the exemptions within the year the exemptions were granted, as required by Tax Code § 41.04.
Tax Code § 41.04 provides:
The appraisal review board is not required to hear or determine a challenge unless the taxing unit initiating the challenge files a petition with the board before June 1 or within 15 days after the date that the appraisal records are submitted to the appraisal review board, whichever is later. The petition must include an explanation for the grounds of the challenge.
Thus, to challenge a potential entry to an appraisal roll, the challenge must be timely brought in that year. But a back-appraisal does not retroactively change previous years’ appraisal rolls. A back-appraisal is included in the appraisal roll for the year in which the failure to back-appraise is challenged. When a taxing unit challenges a back-appraisal in the current year’s appraisal records, it is not challenging past rolls but rather the potential inclusion of past exemptions in the current roll.
See
Tex. Tax Code § 11.43(i); see
also McPhail,
As the County and School District challenge the failure to include a back-appraisal in the then-current 1995 appraisal records, and are not challenging the appraisal rolls for earlier years, the limitations period for the County and School District extended to the later of June 1, 1995, or fifteen days after the submission of the appraisal records to the appraisal review board. See Tex. Tax Code § 41.04. The County and School District brought their challenge on May 31, 1995; therefore, the limitations period had not yet run. The court of appeals erred in affirming the trial court’s summary judgment that the County and School District were barred by limitations from seeking back-appraisal of AHA’s property.
Because we hold that a taxing unit may challenge an appraisal district’s and chief appraiser’s failure to perform the nondis-cretionary duty of back-appraising property that was erroneously exempted in any of the five years preceding the challenge, we reverse that part of the court of appeals’ judgment affirming summary judgment for AHA and remand Petitioners’ claims to the trial court for further proceedings consistent with this opinion.
