Tax Calculation
For sales within the same state, tax is split equally into Central GST (CGST) and State GST (SGST). Both are applied by the seller.
For sales between different states, the full tax amount is applied as Integrated GST (IGST). This simplifies cross-state billing.
Our tool automatically determines the correct GST type and calculates the split based on your entered state codes and transaction details.
