GST (Goods and Services Tax) registration is a critical process for businesses operating in countries that have implemented this tax system, such as India. GST is a comprehensive indirect tax levied on the manufacture, sale, and consumption of goods and services at the national level. It has replaced many indirect tax laws that previously existed in those countries. GST registration is mandatory for businesses exceeding a certain threshold of turnover, providing services or goods across states, or engaging in e-commerce activities, among other criteria which can vary by jurisdiction. The threshold for GST registration varies by country and sometimes within different regions of a country. For example, in India, businesses with a turnover exceeding Rs 40 lakhs (for goods) and Rs 20 lakhs (for services) must register for GST. However, for northeastern and hill states, the threshold is set at Rs 20 lakhs and Rs 10 lakhs, respectively.
