Documents Required for GST Registration

Yes. PAN is mandatory for GST registration for regular taxpayers — the GSTIN is generated based on the PAN. Only a few categories, such as non-resident taxable persons and those required to deduct TDS, may register without a PAN using alternative identification. For a proprietorship the proprietor's personal PAN is used; for a company, LLP or firm the entity's own PAN is required.

The photograph must be in JPEG format with a maximum file size of 100 KB. Other supporting documents (PAN, address proof, bank proof, deeds) are uploaded in PDF or JPEG format, generally up to 1 MB each. All uploads must be clear and legible — blurry scans are a common reason for rejection.

It depends on the entity. Companies and LLPs must sign the GST application with a Class-3 Digital Signature Certificate of the authorised signatory — it is mandatory. Proprietorships and partnerships can instead verify the application using Aadhaar-based EVC (electronic verification code), so a DSC is optional for them.

Yes. You can register a business at your home address. Provide proof such as an electricity bill, property tax receipt or ownership deed for the home. If the home is rented, upload the rent agreement along with a NOC from the landlord. Many small businesses and freelancers register from a home address without any issue.

For rented premises you upload the rent or lease agreement together with a utility bill, and — where the agreement is unregistered or in a third party's name — a No Objection Certificate (NOC) from the property owner. The agreement should be valid on the date of application and the NOC should permit GST registration at the premises.

No. The electricity bill or utility bill used as address proof does not need to be in the business name — it can be in the owner's or landlord's name. What matters is that the address on the bill matches the principal place of business declared in the application, along with a rent agreement or NOC where the premises are not owned by the applicant.

Bank account details are not mandatory at the time of applying. Under Rule 10A you must furnish valid bank account details within 45 days of registration or before filing your first GST return, whichever is earlier. You can add the bank details later through a non-core amendment to the registration.

With successful Aadhaar authentication and complete documents, an ARN is issued immediately and approval typically follows within about 7 working days. If Aadhaar authentication is not done, or the officer flags physical verification of the premises, approval can take up to around 30 days. Prompt responses to any query raised speed up the process.

Aadhaar authentication is the standard and fastest route. If you opt out, the application generally goes through physical verification of the business premises, which extends the timeline to up to 30 days. Ensure your Aadhaar is linked to your active mobile number so the OTP verification succeeds on the first attempt.

A partnership firm needs: the firm's PAN, the partnership deed, PAN and Aadhaar of all partners, passport-size photographs of the partners, proof of the business address, bank account proof in the firm's name and an authorisation letter naming the partner who will apply. Aadhaar-EVC can be used to verify, so a DSC is optional.

A private limited company needs: the company PAN, Certificate of Incorporation, MOA and AOA, PAN and Aadhaar of all directors, photographs of directors, registered-office address proof, bank account proof in the company's name, a board resolution authorising a director as signatory and a Class-3 DSC of that signatory.

An LLP needs: the LLP's PAN, the executed LLP agreement, the LLP's Certificate of Incorporation from the MCA, PAN and Aadhaar of all designated partners, their photographs, registered-office address proof, bank proof in the LLP's name, a resolution authorising a designated partner to sign, and a Class-3 DSC for that partner.

GST registration is state-specific, so you need a separate GSTIN and a fresh application for each state where you have a place of business. The person-related documents (PAN, Aadhaar, DSC) are the same, but you must provide address proof for the place of business in each individual state.

Common reasons are: the business address not matching the uploaded proof, blurry or illegible documents, an expired rent agreement or a missing landlord NOC, Aadhaar not linked to the mobile number so OTP fails, PAN name mismatch or an inactive PAN, and documents uploaded in the wrong category. Fixing these before applying — and responding quickly to any officer query — avoids most rejections.

Yes. If your application is rejected you can file a fresh application once you have corrected the issue — typically a clearer document, a valid rent agreement with NOC, or a matching address. Read the rejection remarks carefully so the same defect is not repeated. Where a query notice (REG-03) was raised first, respond within the given window instead of starting over.
