(a)(1) Within 6 months after the date on which the Mayor mails written denial of an exemption under §§ 47-1002, 47-1005, and 47-1007 to 47-1010, any institution, organization, corporation, or association aggrieved by any assessment, classification, equalization, or valuation of real property deemed to be exempt from taxation under the provisions of §§ 47-1002, 47-1005, and 47-1007 to 47-1010 may appeal to the Superior Court of the District of Columbia in the same manner and to the same extent as is provided in §§ 47-3303 and 47-3304. Payment of the tax bill shall not be a prerequisite for the appeal.
(2) Approval of the assessment rolls described in § 47-825(g) [repealed], shall not preclude the Mayor from making decisions on applications for exemptions filed before July 1st and pending before the Mayor at the time the assessment roll is approved, and all decisions in regard to the application shall be appealable as provided in paragraph (1) of this subsection.
(b)(1) Applications for exemption from the real property tax must be received on or before September 30 to obtain the exemption for the full tax year. If approved, the exemption will become effective as of October 1 of the tax year for which the exemption is granted.
(2) Effective October 1, 1994, and for each tax year thereafter:
(A) Any real property eligible for exemption from real property tax under § 47-1002 shall be exempt from real property tax as of the first month following the date on which a properly completed application has been filed. Real property tax shall be prorated on a monthly basis. The Mayor may prorate the real property tax to the date the property is eligible for an exemption from real property tax. Real property is eligible for an exemption from real property tax if it meets the requirements set forth in § 47-1002 and a properly completed application is filed with the Mayor.
(B) When real property exempt from real property tax, as provided for in this section, becomes ineligible for the exemption, the owner of the real property shall notify the Mayor (in a manner and at a time as the Mayor may prescribe by regulation) of the real property’s ineligibility. The Mayor shall terminate the exemption effective as of the first full month following the date the property became ineligible for the exemption.
