How to claim a property tax exemption after qualifying

(a) Notwithstanding any provision in this chapter to the contrary, any real property exempt from property taxes under section 19-87 shall be exempt except for the minimum tax from property taxes from the date the property is qualified for the exemption; provided that a claim for exemption is filed with the director within sixty days of the qualification. As used herein, the date of the qualification shall be the date when the mortgage made by a nonprofit or limited distribution mortgagor and insured under sections 202, 221(d)(3) or 236 of the National Housing Act is filed for recording with the registrar of the bureau of conveyances or the assistant registrar of the land court of the State, whichever is applicable. (b) After the initial year of the qualification, the claim for exemption shall be filed in the manner provided by applicable law or rule or regulation. (c) In the event property taxes have been paid to the County in advance for real property subsequently becoming qualified for the exemption, the director of finance shall refund to the nonprofit or limited distribution mortgagor owning the property that portion of the taxes attributable to and paid for the period after the qualification.
