Getting your GST registration right at the start saves a great deal of trouble later — from blocked input credit to rejected applications and avoidable notices. This guide walks through who needs to register, what documents you need, and how the process actually works.
Who needs to register for GST?
You must register for GST if any of the following apply:
- Your aggregate turnover crosses the threshold — broadly ₹40 lakh for goods and ₹20 lakh for services (lower in special-category states).
- You make inter-state supplies of goods.
- You sell through an e-commerce operator.
- You are required to pay tax under reverse charge, or you are a casual or non-resident taxable person.
Even when you are below the threshold, voluntary registration is often worthwhile — it lets you claim input tax credit and makes you a more attractive vendor to GST-registered buyers.
Documents you'll need
The exact list depends on your constitution (proprietor, partnership, company), but typically includes:
- PAN of the business and of the proprietor / partners / directors
- Aadhaar of the authorised signatory (for Aadhaar authentication)
- Proof of business address (electricity bill, rent agreement, NOC)
- Bank account details (cancelled cheque or statement)
- Photographs and a board resolution / authorisation letter where applicable
Tip
Keep your address proof and the name on your electricity bill consistent with your application. Mismatched documents are the single most common reason GST applications get queried.
The registration process, step by step
- Generate a TRN on the GST portal using your PAN, email and mobile.
- Complete Part B of the application with business details, place(s) of business, and authorised signatory.
- Upload documents and complete Aadhaar authentication.
- Submit with DSC (for companies/LLPs) or EVC.
- The officer either approves the application or raises a query, which must be answered within the prescribed time.
Once approved, you receive your GSTIN and registration certificate, and can begin issuing GST-compliant invoices.
Common mistakes to avoid
- Choosing the wrong registration type (regular vs composition) for your business model.
- Missing an additional place of business that should have been declared.
- Ignoring Aadhaar authentication, which delays approval.
- Treating registration as the finish line — your real obligation is timely, accurate return filing thereafter.
