Break an invoice into its tax parts

A GST invoice total combines the taxable value and the tax, and for accounting you often need them separated, with the tax split into its components. This tool splits an invoice amount into its taxable value and GST, supporting the intra-state split into CGST and SGST as well as inter-state IGST.

Why intra-state and inter-state differ

GST is charged differently depending on whether a supply is within a state or across states. An intra-state supply splits the GST into CGST (central) and SGST (state) in equal halves; an inter-state supply charges a single IGST at the full rate. Getting this split right is essential for correct returns, because the components are reported and credited separately. The tool applies the right split for the type of supply so the invoice reconciles.

Frequently Asked Questions

What is the difference between CGST/SGST and IGST?

An intra-state supply splits GST into CGST and SGST, each half the rate; an inter-state supply charges a single IGST at the full rate. The tool handles both.

Why split an invoice into taxable value and GST?

Because accounting and GST returns need them separated, and the tax must be broken into its correct components for reporting and input credit.

How is the taxable value found from the total?

By reversing the GST out of the inclusive amount, dividing by one plus the rate, then splitting the tax into the right components.

When do I use IGST versus CGST and SGST?

IGST for supplies across state lines, CGST and SGST for supplies within a state. The type of supply determines which applies.
