GST Documents by Business Type

The list changes with how your business is registered. Applying with the wrong set is the most common reason a GST application comes back.

Everyone needs these

  • PAN of the business — and for a proprietorship that is the proprietor's own PAN
  • Aadhaar of the applicant, with authentication
  • Photograph of the proprietor, partners or directors as applicable
  • Proof of the principal place of business — ownership document, or a rent agreement with the owner's NOC and a recent utility bill
  • Bank details — a cancelled cheque or statement in the business name
  • Email and mobile that you control, since verification is by OTP

What changes by structure

StructureAdditional documents
ProprietorshipNothing beyond the base list — the proprietor is the business, so their PAN and Aadhaar carry it
Partnership firmPartnership deed, and an authorisation letter signed by the partners naming the authorised signatory
LLPCertificate of incorporation, LLP agreement, and authorisation for the designated partner
CompanyCertificate of incorporation, MOA and AOA, and a board resolution authorising the signatory
Society or trustRegistration certificate, the trust deed or bye-laws, and an authorisation from the governing body naming the signatory

The authorisation is the part most often missing or wrong. It has to name a specific person, be signed by whoever has authority to appoint them, and be dated. A generic letter with no name, or one signed by the person authorising themselves, gets queried.

Where applications actually fail

Rarely a missing document — those get asked for. What fails applications is inconsistency and address proof.

  • Business name spelled differently across PAN, bank and registration documents. Pick the PAN version and match everything to it.
  • Address proof not in the right name, or a rent agreement with no NOC from the owner.
  • An electricity bill that is too old or in a previous occupant's name.
  • Authorisation letter naming nobody, or naming someone who is not on the deed or the board.
  • Bank account not in the business name for a registered entity.

Common questions

For a company, LLP or firm, an account in the entity's name is needed. A proprietor can often use their existing account, though a separate one is better practice.

Yes, with proper proof — ownership document or NOC from the owner, plus a utility bill. Home-based registration is common and perfectly legitimate.

Yes. It is short, it has to be right, and getting it wrong costs a query and a week.

Usually a few working days when documents are clean. Queries are what extend it, and they nearly always trace back to one of the five points above.
