(b)(1) For purposes of applying the disabled veterans' property tax exemption set forth in Section 205.5 of the Revenue and Taxation Code, any amount of tax, including any interest or penalty thereon, levied upon that portion of the assessed value of real property that would have been exempt if the veteran's pending application for certification of disability had been finalized, shall be canceled or refunded if both of the following conditions are met:

(2) Any refund issued pursuant to this subdivision is subject to the limitations periods for refunds set forth in Section 5097 of the Revenue and Taxation Code.
