GST registration applications require disposal only on prescribed documents, with proper consideration of premises-specific proof and Form GST REG-01 requirements. Registration applications under the U.P. GST framework must be disposed of in accordance with Section 25 of the GST Act, Rules 8 and 9, Form GST REG-01, and issued instructions. The prescribed documents vary by premises: property tax receipt, municipal account copy, or electricity bill for own premises; rent or lease agreement with ownership proof for rented premises; consent letter with ownership proof for other or shared premises; affidavit with possession proof where no rent or lease agreement exists; and specified Government of India documents for SEZ cases, along with bank-account certificates and separate authorization letters.
