Goods and Services Tax (GST) is India's comprehensive indirect tax system that replaced multiple cascading taxes. It is levied on the supply of goods and services across the country. GST has four main slabs: 5%, 12%, 18%, and 28%, with some goods at 0% and luxury items attracting additional cess.
For intra-state transactions (within the same state), GST is split equally into CGST (Central GST) and SGST (State GST). For inter-state transactions, the entire GST is charged as IGST (Integrated GST). Our calculator automatically computes all three components so you can accurately prepare invoices and understand your tax liability.
Calculate for 5%, 12%, 18%, and 28% GST rates used across India.
