A supplier of goods, with an annual turnover of Rs. 40 lakh (Rs. 20 lakhs for special category States), must apply for GST registration. There are certain cases where the taxable person is liable to pay GST even though his turnover has not crossed this limit.
Those providing services must get GST registration, once their turnover crosses Rs.20 lakhs and in case of Special Category States at Rs 10 lakhs.
