What is GST Registration?

GST (Goods and Services Tax) is a unified indirect tax that replaced various state and central taxes in India. If your business exceeds a certain turnover threshold or falls under specific categories, you’re legally required to register for GST.

Under the GST Act, any individual or business supplying goods or services above the prescribed turnover limit must register. As of 2025, the thresholds remain:

• ₹40 lakh for suppliers of goods (₹20 lakh in some special category states)

• ₹20 lakh for service providers (₹10 lakh in special category states)
