The GST Council has set different turnover thresholds for mandatory registration based on business type and state location:
Annual turnover exceeding ₹40 lakh in most states requires mandatory GST registration. For special category states (NE states + Himachal Pradesh, Uttarakhand, J&K), the threshold is ₹20 lakh.
Annual turnover exceeding ₹20 lakh requires mandatory GST registration. For special category states, the threshold is ₹10 lakh.
Certain businesses must register regardless of how small their turnover is: E-commerce sellers (on any platform), inter-state suppliers, exporters, businesses under reverse charge mechanism, and casual taxable persons.
Operating without GST registration when it's mandatory is a serious compliance violation with steep penalties:
Beyond penalties, you'll lose the ability to issue valid GST invoices, claim Input Tax Credit, and supply to GST-registered businesses (who need your GSTIN for their ITC claims). This effectively shuts you out of B2B supply chains.
