How GST is calculated in India
In India, the statutory goods and services tax rate of 18% is applied to taxable products and services.
Add Tax (Exclusive): Gross = Net × (1 + 0.18)
Reverse Tax (Inclusive): Net = Gross ÷ (1 + 0.18)
Extracted Tax: Tax Amount = Gross - Net
Invoicing & Compliance Best Practices
- Tax Invoices: Clearly separate the pre-tax net sum from the statutory 18% GST line item.
- Reverse Charge: For cross-border B2B purchases, verify whether reverse-charge accounting mechanisms apply under local regulations.
- Exemptions: Certain essential items (such as healthcare, education, or staple foods) may qualify for zero-rating or reduced rates.
