The Goods and Services Tax (GST) registration process is online and must be completed on the government website at gst.gov.in. Every dealer whose annual turnover exceeds Rs 20 lakh (Rs 40 lakh or Rs 10 lakh, depending on state and type of goods) is required to register for GST. It should be noted that people registering for GST must complete the GST REG-01 form. The GST REG-01 form can be completed online and is absolutely free of charge. This form is broken into two parts: Part A and Part B. It is critical that both Parts A and B are filled out correctly, or else the GST registration will not be completed.
