A supplier must register under GST once aggregate turnover crosses ₹40 lakh for suppliers of goods, or ₹20 lakh for suppliers of services. Lower limits apply in some special category states. These thresholds apply in Maharashtra.
Certain persons must register regardless of turnover. These include those making inter-state taxable supplies of goods, sellers through e-commerce operators (subject to exceptions), casual taxable persons and persons liable under reverse charge.
