Intra-state: two tax lines, half each
Both parties are in the same state, so each slab splits down the middle — an 18% item shows 9% CGST and 9% SGST as separate lines. One combined "18% GST" line is not a valid tax invoice.
| Item | Qty | Slab | Taxable | CGST + SGST | Total |
|---|---|---|---|---|---|
| Website design | 1 | 18% | ₹1,00,000 | ₹9,000 + ₹9,000 | ₹1,18,000 |
| Printed brochures | 2 | 5% | ₹10,000 | ₹250 + ₹250 | ₹10,500 |
