   Analysis

   Home offices draw more queries and sometimes a physical visit, because the officer wants to see that business is actually done there. If your father owns the house, upload his electricity bill or tax receipt with a signed consent letter and his ID. A board or nameplate showing the business name helps in a site visit. Instruction 03/2025-GST limits officers from asking for documents beyond those prescribed, so you can point to it if asked for unusual papers.
