GST in India is a dual taxation system.
In case of Local Sales (Within State), both center and state have share in the amount of tax. So we charge SGST [50%] and CGST [50%].
In case of Central Sales (Interstate). Only Central Govt. has right to get tax amount. So we charge IGST from customer.
Here’s how we’ll create tax slab
For example if GST is 12%, Then SGST and CGST will be 6% and 6% respectively. IGST will be defined as 12%.
