Upon receipt of an application under paragraph I(b), the selectmen or assessors shall review the application and shall grant, for good cause shown, or deny the application in writing by July 1 after notice of tax date under RSA 76:1-a. The failure to respond shall constitute denial. All such written decisions shall be sent by first class mail to the taxpayer and shall include a notice of the appeal procedure under RSA 76:16-a and RSA 76:17 and of the deadline for such an appeal. The board of tax and land appeals shall prepare a form for this purpose.
