Documents Required for GST Registration

Step-by-Step GST Registration Process

1

Visit the GST Portal

Go to gst.gov.in → Services → Registration → New Registration.

2

Fill Part-A of Form REG-01

Select taxpayer type (Taxpayer / Composition / Casual). Enter your PAN, mobile number, and email address. Verify both with OTPs. You will receive a Temporary Reference Number (TRN) — save it.

3

Fill Part-B — 15 Sections

Use the TRN to log back in and complete Part-B. You have 15 days to complete after generating TRN. Sections include: Business details, legal name, trade name, business constitution, principal place of business, additional places of business, goods/services details, bank account details, state-specific details, Aadhaar authentication, and authorized signatory information.

4

Upload Documents

Upload scanned copies of PAN, Aadhaar, photos, address proofs, and bank documents as applicable to your business type (see checklist above).

5

Submit the Application

Submit using one of: Aadhaar e-sign (OTP-based, recommended — faster processing) or DSC (Digital Signature Certificate — required for companies). An Application Reference Number (ARN) is generated and sent to your mobile and email.

6

Receive GSTIN Certificate

If Aadhaar-authenticated: GSTIN issued within 7 working days automatically. If not Aadhaar-authenticated: A GST officer may conduct physical verification (site visit), taking up to 30 working days. The GST Registration Certificate (Form GST REG-06) is available on the portal.

GST Registration Fees

The government fee for GST registration is NIL — there are no government charges. Professional/CA charges for assisted registration typically range from ₹1,500 to ₹3,000 for simple cases. FinsyncX charges ₹999 for proprietorship registration.

How Long Does GST Registration Take?

• Aadhaar-authenticated applications: 7 working days
• Non-authenticated / physical verification: Up to 30 working days
• If officer issues Form GST REG-03 (clarification request): You have 7 working days to respond; total time may extend to 30 days
• Provisional GSTIN: If no action within 3 working days (Aadhaar authenticated), a provisional GSTIN is granted automatically

Common Mistakes to Avoid

• Wrong PAN: Ensure the PAN entered matches exactly with Income Tax records
• Expired documents: Aadhaar and PAN must be valid and linked to each other
• Wrong address proof: The address in the utility bill must match the registered address
• Not selecting correct business activity: Choose the right HSN (goods) or SAC (services) codes in Section 8
• Bank account mismatch: Account should be in the name of the business/proprietor, not a personal account in another name
• Incomplete Part-B: The 15-day window to complete Part-B after TRN generation — if you miss this, you have to restart
