Such application may be filed by mail if it is enclosed in a postpaid envelope properly addressed to the appropriate assessor, deposited in a post office or official depository under the exclusive care of the United States postal service, and postmarked by the United States postal service on or before the applicable taxable status date. Each such application shall be made on a form prescribed by the commissioner, which shall require the applicant or applicants to agree to notify the assessor if their primary residence changes while their property is receiving the exemption. The assessor may request that proof of residency be submitted with the application.

If the application was filed prior to October first, two thousand thirteen, the penalty tax shall be one hundred dollars, provided that the assessor's determination must be made within three years of the filing of the application. If the application was filed on or after October first, two thousand thirteen, the penalty tax shall be either one hundred dollars or twenty percent of the improperly received tax savings, whichever is greater not to exceed two thousand five hundred dollars, provided further that the assessor's determination must be made within six years of the filing of the application.
