📋 Complete Guide to GST Registration for Startups

Who Needs GST Registration?

GST registration is mandatory if your annual turnover exceeds ₹40 lakhs (₹20 lakhs for special category states). However, startups should consider voluntary registration even below this threshold for several benefits: input tax credit, professional credibility, and ability to sell to businesses that need GST invoices.

• Turnover > ₹40L (₹20L for special states): Mandatory
• Interstate supply of goods/services: Mandatory regardless of turnover
• E-commerce sellers: Mandatory from day one
• Voluntary registration: Allowed for any business

• PAN Card of business entity
• Aadhaar Card of proprietor/authorized signatory
• Business address proof (rent agreement, electricity bill)
• Bank account statement/cancelled cheque
• Digital signature (for companies/LLPs)
• Board resolution (for companies)
• Partnership deed (for partnerships)
