What is GST Inclusive?

GST Inclusive means the price already includes the tax amount. Use the inclusive option when you need to separate the GST amount from the total price. For example, if a product costs ₹118 (inclusive of 18% GST), the base price is ₹100 and the GST component is ₹18.

What is GST Exclusive?

GST Exclusive means the price doesn't include tax. Use this option to calculate the total price after adding GST to the base amount. For example, if a product's base price is ₹100 with 18% GST, the total payable amount would be ₹118 (₹100 + ₹18 GST).

What are CGST and SGST?

In India, GST is divided into two equal parts: CGST (Central Goods and Services Tax) and SGST (State Goods and Services Tax). Each component represents 50% of the total GST amount. For interstate transactions, IGST (Integrated Goods and Services Tax) is applicable instead.
