Frequently Asked Questions
1. What is the difference between GST Inclusive and Exclusive?
GST Exclusive means GST is added on top of the net base price. GST Inclusive means the bill price already includes GST tax.
2. How are CGST and SGST calculated?
For Intra-State sales (within same state), GST is split 50% as Central GST (CGST) and 50% as State GST (SGST).
3. When is IGST applicable?
Integrated GST (IGST) is applied when goods or services are sold inter-state (between two different states).
4. How is Exclusive GST calculated?
Formula: GST Amount = (Base Price * Rate) / 100. Gross Total = Base Price + GST Amount.
5. How is Inclusive GST extracted?
Formula: GST Amount = Total - [Total * (100 / (100 + Rate))].
