How GST Split Calculations Work: CGST, SGST & IGST

1. Indian GST Components

GST is divided into Central GST (CGST) and State GST (SGST) for transactions within a state, and Integrated GST (IGST) for transactions between states. Our calculator automates these splits for billing.

2. Calculating Tax-Inclusive Prices

To extract the base price from a GST-inclusive amount, apply the formula: Base = Total / (1 + GST Rate). This allows you to verify supplier calculations accurately.

2.1 CGST and SGST 50/50 Splits

For transactions within the same state, the total GST amount is always split equally between CGST and SGST accounts.

Frequently Asked Questions

What is the difference between inclusive and exclusive GST?

Inclusive means the product price already covers tax, whereas exclusive means tax is added on top of the base price.
