Principal place of business proofs
The official GST portal checklist includes property tax receipt, municipal khata copy, electricity bill, rent/lease agreement, consent letter and government-issued documents among the accepted categories. The required combination varies for owned, rented/leased, consent/shared and other premises situations.
Authorised signatory documents
Companies and other entities may need a letter of authorisation or board/managing committee resolution and acceptance documentation. The authorised signatory’s identity details must align with the application and authentication route.

The official document checklist specifies JPG/PDF formats and document-specific upload sizes. Because these portal limits can be updated, check the current checklist at filing time instead of relying on an old screenshot.
