How Invoixa Handles GST Calculations

Under the Goods and Services Tax framework in India, the application of taxes depends squarely on the Place of Supply. Invoixa eliminates human error by matching state codes dynamically.

Intra-State Supply Seller = Buyer State

Same State (e.g. Karnataka → Karnataka)

When your business and your client are registered in the same state, the total applicable GST is divided equally into two components:

CGST 9% Central GST to Union Govt

SGST 9% State GST to Local State

Invoixa Action: Automatically prints two distinct lines on the tax breakdown table to ensure valid Input Tax Credit (ITC) for your client.

Inter-State Supply Seller ≠ Buyer State

Different States (e.g. Karnataka → Maharashtra)

When billing a client located in a different Indian state, the entire tax is levied as Integrated Goods and Services Tax:

IGST 18% Integrated GST (Single Consolidated Levy)

Invoixa Action: Maps state code prefix (e.g. 29 to 27) and applies unified IGST, generating the proper GSTR-1 export report syntax.
