Apply for GST registration online in 2026 through gst.gov.in. Step-by-step guide for businesses covering thresholds, documents, and post-registration setup.
GST registration in 2026 is entirely online through gst.gov.in. Once your turnover crosses the prescribed threshold or you fall under a compulsory-registration category, you must obtain a GSTIN to legally issue tax invoices, claim input tax credit, and supply across state lines. With the GST portal's Aadhaar-authentication route now widely adopted, a well-prepared application can be approved in 3 to 7 working days.
When Registration Is Mandatory
- Turnover exceeds ā¹40 lakh for goods or ā¹20 lakh for services
- ā¹10 lakh threshold for special-category states
- Inter-state supply of taxable goods or services
- Selling through e-commerce operators such as Amazon, Flipkart, or Meesho
- Casual taxable persons and non-resident taxable persons
- Entities liable to deduct TDS or collect TCS under GST
- Input Service Distributors and reverse-charge supplies
Documents Required
- PAN of the business and authorised signatory
- Aadhaar of the authorised signatory for OTP-based authentication
- Constitution proof: incorporation certificate, partnership deed, or registration document
- Proof of principal place of business: rent agreement, NOC, utility bill, or ownership document
- Bank account details with a cancelled cheque or bank statement
- Authorised signatory authorisation letter and photograph
- Digital Signature Certificate for companies and LLPs
Step-by-Step Application
- Visit gst.gov.in and click Register Now under New Registration
- Fill Part A with PAN, mobile, and email; receive TRN after OTP verification
- Log in with TRN and complete Part B with business details, promoters, place of business, bank details, and goods or services
- Upload all required documents in prescribed format
- Complete Aadhaar authentication for the authorised signatory to skip physical verification
- Submit with DSC for companies and LLPs or EVC for others
- Receive ARN and track status; GSTIN is typically issued in 3 to 7 working days
Post-Registration Setup
Once your GSTIN is active, display it at every place of business, mention it on invoices and letterheads, and configure your accounting software with the new GSTIN. Set up monthly or quarterly return calendars for GSTR-1 and GSTR-3B, reconcile GSTR-2B with purchase records, and prepare for e-invoicing if your turnover crosses the prevailing threshold. File a nil return even in months without transactions to keep the GSTIN compliant.
Common Mistakes
- Mismatched legal name across PAN, GST, and MCA records
- Incorrect HSN or SAC codes for principal goods or services
- Wrong jurisdiction selection during application
- Skipping Aadhaar authentication and inviting physical verification delays
- Listing only one place of business when multiple branches operate
Conclusion
Online GST registration in 2026 is fast when paperwork is clean and Aadhaar authentication is completed. Treat the application as the start of a long compliance journey, set up monthly filing rhythms, and reconcile input tax credit regularly to capture every rupee of legitimate ITC.
