Removing GST, step by step
Say a client agrees to pay ₹59,000 including 18% GST. Divide by 1.18 to get the taxable value: ₹59,000 ÷ 1.18 = ₹50,000. The GST is ₹59,000 − ₹50,000 = ₹9,000. Within your state that is ₹4,500 CGST and ₹4,500 SGST; to another state it is ₹9,000 IGST.
| Inclusive price | Rate | Divide by | Before GST | GST inside |
|---|---|---|---|---|
| ₹1,050 | 5% | 1.05 | ₹1,000 | ₹50 |
| ₹11,800 | 18% | 1.18 | ₹10,000 | ₹1,800 |
| ₹59,000 | 18% | 1.18 | ₹50,000 | ₹9,000 |
| ₹1,40,000 | 40% | 1.40 | ₹1,00,000 | ₹40,000 |
