GST Registration Documents and Eligibility: Complete Checklist

For GST Registration you need the PAN of the business, the Aadhaar and photographs of the proprietor, partners or directors, proof of how the business is constituted, proof of the principal place of business, an authorisation for the signatory, and bank account details. Everything is uploaded online — there is no paper filing.

GST Registration is applied for on the GST portal. These are the documents usually needed. Scans should be clear, and names and addresses should match PAN and Aadhaar exactly — most queries from officers come from small mismatches. A printable, entity-wise checklist is in the blog post GST Registration documents required and eligibility checklist; this lesson explains why each document is asked for and where people go wrong.

Which GST Registration documents are required from every applicant?

• PAN of the business (or of the proprietor).
• Aadhaar of the proprietor, partners or directors — used for authentication.
• Photograph of the proprietor, partners or directors.
• Mobile number and email address of the authorised signatory.
• Bank account details — cancelled cheque or bank statement.

Bank details can also be added after the GSTIN is issued: under Rule 10A of the CGST Rules, they must be furnished within 30 days of Registration or before filing GSTR-1, whichever is earlier.

The bank account should be in the name of the business — or, for a proprietorship, in the proprietor's name. A company or LLP cannot normally use a director's or partner's personal account.

What is accepted as proof of business constitution?

"Constitution" simply means the legal form of the business — company, LLP, firm or proprietorship. The proof is the document that brought that form into existence.

Type of business	Proof of constitution	Who authenticates
Company	Certificate of Incorporation	Directors and authorised signatory
LLP	Certificate of Incorporation	Designated partners and authorised signatory
Partnership firm	Partnership deed	Partners and authorised signatory
Proprietorship	PAN and Aadhaar of the proprietor	Proprietor

A proprietorship has no separate legal identity, so it has no incorporation certificate or deed — the proprietor's own PAN is used, and the GSTIN is built on it. A newly formed PVT. LTD. or LLP must wait for its incorporation and PAN before applying, because the GSTIN is based on the entity's own PAN.

What is accepted as proof of the principal place of business?

The "principal place of business" is the main address from which the business is run in that state. Any other godown, shop or office in the same state is added as an additional place of business, with its own proof.

• Own premises — electricity bill, property tax receipt or municipal khata.
• Rented premises — rent agreement plus the owner's utility bill.
• Consented premises — consent letter or NOC plus the owner's utility bill.

A home address can be registered if the business is actually run from there. Officers may visit the premises, so the address given should be one where the business can be found.

Shared offices, co-working desks and virtual offices raise their own questions; these are covered in the blog post GST Registration without a commercial address: home, rented and virtual office rules.

Who signs, and what authorisation is needed?

A board resolution (company) or authorisation letter (LLP or firm) naming the authorised signatory.

Companies and LLPs must sign the application with a Digital Signature Certificate (DSC) of the authorised signatory. Proprietors and firms can use EVC — a one-time password sent to the signatory's mobile.

The authorised signatory is the person who will sign returns and deal with the GST department for the business. In a proprietorship this is usually the proprietor. The signatory's DSC must be registered on the GST portal before it can be used.

Is Aadhaar authentication needed?

Aadhaar authentication of the promoters and authorised signatory is part of the Registration process and speeds up approval. Depending on risk checks, some applicants are asked to visit a GST Suvidha Kendra for biometric authentication, a photograph and verification of original documents before the application moves ahead.

The mobile number linked to each person's Aadhaar should be active, because the authentication link and OTP are sent to it. Under the simplified Rule 14A route, Aadhaar authentication is mandatory.

What are the common document mistakes?

• The business name in the application differs from the name on PAN, even by a word or an abbreviation.
• The address on the utility bill differs from the address typed in the form — a missing flat number or wing is enough to trigger a query.
• An old electricity bill, or a rent agreement that has expired.
• A consent letter that is unsigned, or signed by someone who is not the owner.
• A blurred, cropped or oversized scan that the portal or the officer cannot read.
• Uploading a personal bank account for a company or LLP.

Each of these usually leads to a notice in Form REG-03, which adds days to the process. The steps and timelines are explained in the lesson on the GST Registration process.

Who is eligible for GST Registration?

GST Registration eligibility is broad. You can apply if you are:

• an individual running a business as a proprietor;
• a Hindu Undivided Family (HUF), partnership firm, LLP, company, trust, society or other association;
• a government body or local authority making taxable supplies;
• a casual taxable person (doing business temporarily in a state) or a non-resident taxable person, under special procedures.

The basic condition is a valid PAN (non-resident taxable persons apply with their passport and other documents instead). Eligibility is not the same as obligation: you must register when your turnover crosses the limit — ₹40 lakh for goods only, ₹20 lakh for services in most states — or when Section 24 applies, such as for inter-state sales of goods. Below that, you may register voluntarily. See Who must register for GST? and, for service businesses, GST Registration for freelancers, service providers and startups.

How should documents be prepared?

• Match names exactly. The legal name must match PAN; the signatory's name must match Aadhaar. Small spelling differences are a common reason for officer queries.
• Match the address exactly. The address you type should match the address proof, including floor, unit number and PIN code.
• Use clear scans in the format and size the portal accepts (generally PDF or JPEG with size limits shown on the upload screen).
• Keep Aadhaar linked to a working mobile number. Aadhaar OTP authentication of promoters and the signatory speeds up approval; without it, physical verification is more likely.
• Do not add documents the law does not ask for. Officers have been told not to demand items such as Udyam or shop licence certificates for GST Registration.

The chapter Documents for GST Registration explains each item in more depth, and The GST Registration process walks through the form.

What happens if a document is missing or unclear?

The officer issues a notice in Form GST REG-03 asking for clarification or the missing document. You reply in Form GST REG-04 within seven working days. Officers have been instructed to raise queries only about the documents actually filed — for example, an illegible scan, an address that does not match the proof, or a previously cancelled GSTIN on the same PAN. If you do not reply, or the reply is not satisfactory, the application can be rejected in Form GST REG-05, and you would need to apply again.

Key takeaways

• PAN, Aadhaar, photo, bank details and address proof are the core.
• Constitution proof depends on the type of business.
• Aadhaar authentication speeds up approval, and is mandatory under Rule 14A.
• Companies and LLPs need a DSC; others can use EVC.
• Names and addresses must match PAN and the address proof exactly.
