Taxpayer assigns error to the Commission’s decision and argues that the Machinery Act presently allows either a county tax supervisor or board of equalization and review to grant an exemption when the owner has listed his property during the listing period but does not apply for exempt status until after this period. We disagree for the reasons given in the Commission’s decision.
The Commission based its decision on the express mandate set out in G.S. 105-282.1(a):
Every owner of property claiming exemption or exclusion from property taxes under the provisions of this Subchapter has the burden of establishing that the property is entitled thereto. Except as otherwise provided below, every owner claiming exemption or exclusion hereunder shall annually, during the regular listing period, file an application therefor *744with the tax supervisor of the county in which the property would be subject to taxes if taxable. (Emphasis added.)
The Commission emphasized that this statutory requirement allows no flexibility for the filing of an application for exemption after the listing period. The rationale for this strict application is “to enable the taxing officials to determine the reductions in their tax base prior to setting the tax rate.”
Taxpayer here listed its property during the 1982 listing period, which ended on 2 March 1982. The property was therefore included in the tax base relied upon by the Tax Supervisor when he submitted projected revenues to the County Manager prior to 30 April as required by G.S. 159-10. The Board of County Commissioners was required to adopt a budget ordinance making appropriations and levying taxes upon this tax base not later than 1 July. G.S. 15943(a). By the time Taxpayer applied for exempt status on 30 June, the County’s budget ordinance was established. Allowing removal of a taxpayer’s listed property from the tax base after the listing period has closed and the county has relied upon this tax base in projecting revenues and proposing a budget would clearly jeopardize the county’s budget.
We find no merit to Taxpayer’s argument that G.S. 105-282.1(c) allows either a tax supervisor or board of equalization and review to consider the merits of a late application for exemption of listed property. This statute provides in part:
When an owner of property who is required to file an application for exemption or exclusion fails to do so, the tax supervisor shall proceed to discover the property as provided in G.S. 105-312. If upon appeal to the county board of equalization and review or board of commissioners, the owner demonstrates that the property meets the conditions for exemption, the exemption may be approved by the board at that time.
Taxpayer argues that the Commission’s interpretation of the foregoing statute as allowing review of the exempt status of a taxpayer who fails to list his property, but denying a hearing to a taxpayer who lists his property and does not file an application for exemption until after the listing period, is absurd. This argument can be refuted on two grounds. First, the Legislature has *745defined the phrase “to discover property” as “the determination that property has not been listed during a regular listing period and to the identification of the omitted item.” G.S. 105-312(a)(3). This language is clear that property can only be discovered if it is not listed. G.S. 105-282.1(c), therefore, does not apply to Taxpayer’s timely listed property. Second, an owner of discovered property which meets the conditions for exemption is allowed an exemption after the listing period, because his unlisted property was never included in the county’s tax base. Granting an exemption to unlisted property would not jeopardize the budget adopted by the county.
Taxpayer’s remaining assignment of error involves the constitutional validity of the Commission’s interpretation of G.S. 105-282.1. Since this issue was not raised before the Board of Equalization and Review and since the one issue before the Property Tax Commission did not include constitutional questions, Taxpayer cannot raise the issue on appeal to this Court. See White v. Pate, 308 N.C. 759, 304 S.E. 2d 199 (1983).
