For intra-state transactions, GST is split equally between Central (CGST) and State (SGST) governments. For inter-state transactions, IGST (Integrated GST) is levied by the Centre and then shared with the destination state.
Most services are taxed at 18% GST. Some services like healthcare, education, and certain banking services are exempt. Financial services and insurance attract 18%, while life insurance has a complex blended rate.
Businesses with annual turnover exceeding ₹40 lakh (₹20 lakh for special category states) must register for GST. For service providers, the threshold is ₹20 lakh (₹10 lakh for special states).
