The Founder’s Checklist for GST Registration: Documents, Timelines & Common Pitfalls
Everything you need to know about 15-digit GSTIN acquisition, Aadhaar OTP authentication, and how to avoid REG-03 clarification notices.
Mandatory vs Voluntary GST Registration
Under Indian Goods and Services Tax law, registration is mandatory once an aggregate turnover surpasses ₹40 Lakhs for goods suppliers (₹20 Lakhs in hill and special category states) and ₹20 Lakhs for service providers.
However, registration is compulsory irrespective of turnover if you sell goods across state borders, sell through e-commerce portals like Amazon or Flipkart, or act as an input service distributor.
Many B2B startups opt for voluntary GST registration from day one to claim Input Tax Credit (ITC) on office computers, software subscriptions, and commercial leases.
Essential Document Checklist
Tax officers scrutinize registered address documents rigorously. Ensure scanned copies meet clarity requirements:
- PAN Card and Aadhaar Card of the proprietor, partners, or directors
- Passport-sized photograph of primary authorized signatory
- Cancelled bank cheque or bank statement with company account details
- Electricity bill or Municipal Property tax receipt under 2 months old
- Signed No Objection Certificate (NOC) and rent deed (if rented premise)
Why REG-03 Notices Happen and How to Prevent Them
The most common cause of delayed GSTIN issuance is Form REG-03 (Notice seeking clarification). This typically happens when the electricity bill address spelling differs slightly from the rent agreement or Aadhaar address.
At RegistrationSarthi, our tax specialists verify land records and municipal mapping before submitting Form REG-01, reducing queries to under 2% of filings.
