GST Registration Process for New Business: Your Complete Compliance Roadmap

GST registration is mandatory for businesses with aggregate turnover exceeding ₹40 lakh (₹20 lakh for special category states) for goods, and ₹20 lakh (₹10 lakh for special states) for services. The process is entirely online via the official GST portal. Understanding eligibility, documentation, and the workflow ensures compliance without delays.

Eligibility and Mandatory Registration Triggers

If you supply goods or services across states, GST registration is mandatory even below ₹20 lakh turnover. Key registration triggers include:

E-commerce sellers on Amazon, Flipkart, Meesho, or Shopify
Interstate suppliers and service providers
Freelancers offering design, IT, or consultancy services
Foreign businesses supplying goods or services in India
Temporary stalls and event-based sellers

Most clean applications are processed in 2-6 business days. Voluntary registration below the threshold offers input tax credit eligibility and B2B credibility.

Turnover Thresholds and Special Category States

Goods suppliers must register when turnover exceeds ₹40 lakh, while special category states have a ₹20 lakh threshold. Service providers face a ₹20 lakh limit, reduced to ₹10 lakh in special category states. Registration becomes mandatory within 30 days of crossing the threshold.
