Not sure if you need to register for GST? Or already registered but confused about what comes next? This guide covers the essentials — thresholds, process, documents, and what happens after you get your GSTIN.
GST Registration Thresholds (2026)
- Goods: Mandatory registration if annual turnover exceeds ₹40 lakh (₹20 lakh for special category states)
- Services: Mandatory if annual turnover exceeds ₹20 lakh (₹10 lakh for special category states)
- E-commerce sellers: Mandatory regardless of turnover
- Interstate supply: Mandatory regardless of turnover
Voluntary Registration — Should You?
Even if your turnover is below the threshold, voluntary GST registration is often worth it. It makes you eligible to claim Input Tax Credit on your purchases, allows you to sell to GST-registered businesses (many prefer GST invoices), and lends credibility to your business.
Documents Required for GST Registration
- PAN card of business/proprietor
- Aadhaar card of proprietor/partners/directors
- Proof of business registration (if applicable)
- Bank account statement or cancelled cheque
- Address proof for business premises (rent agreement or electricity bill)
- Passport-size photograph
- Digital signature certificate (for companies/LLPs)
The Registration Process (Step by Step)
- Go to gst.gov.in → Services → Registration → New Registration

After Getting Your GSTIN
Once registered, you must file GSTR-1 (sales summary) and GSTR-3B (tax summary) every month, maintain proper books, and display your GSTIN on all invoices, signboards, and correspondence. Credwik automates all of this so compliance doesn't become a burden.
