Here is how a line for roofing sheet looks on a tax invoice within one state: 40 × sheet at Rs 1,500.00 each, taxed at 18%. The figures are an example, not a market price.
| Item | HSN | Qty | Rate (Rs) | Taxable (Rs) | CGST (Rs) | SGST (Rs) | Total (Rs) |
|---|---|---|---|---|---|---|---|
| Roofing Sheet | 7210 | 40 × sheet | 1,500.00 | 60,000.00 | 5,400.00 | 5,400.00 | 70,800.00 |
Sold to a buyer in another state, the same line carries IGST of Rs 10,800.00 instead of CGST and SGST. Make the full invoice with the GST invoice format: it fills in the tax split, round off and amount in words.
Chapter 72 (Iron and steel) covers: Pig iron, scrap, ingots, bars, rods, sheets, coils, wire and sections of iron or steel.
