How the Calculation Works

Example Calculation
For example, a GST amount can be split into CGST and SGST for intra-state invoices.
A GST amount of 18,000 can be shown as 9,000 CGST and 9,000 SGST for a simple intra-state split. Replace the sample values with your own numbers before using the estimate for planning.
