CGST, SGST and IGST, explained with examples

GST in India is split between the Centre and the States. Which parts you charge depends on whether the sale crosses a state border.

01What each one means

  • CGST: Central GST, collected by the Centre.
  • SGST: State GST, collected by the State.
  • UTGST: Union Territory GST, used instead of SGST in some union territories.
  • IGST: Integrated GST, charged on inter-state supplies and imports.

02The simple rule

Supplier and place of supplyCharge
Same stateCGST + SGST (half each)
Different statesIGST (full rate)

03Example 1: within Delhi

A Delhi business sells services worth ₹10,000 at 18% to a Delhi client. It charges 9% CGST (₹900) + 9% SGST (₹900). Total ₹11,800.

04Example 2: Delhi to Maharashtra

The same sale to a client in Mumbai attracts 18% IGST (₹1,800). Total is still ₹11,800, but the tax goes to a different head.

05Let software decide

SuperForge compares your state with the buyer's place of supply and applies CGST + SGST or IGST automatically on every invoice.

06Questions

When is IGST charged?

On inter-state supplies, where the supplier and place of supply are in different states, and on imports.

Is the total tax different for IGST?

No. The rate is the same; only how it's split and who collects it changes.
