❓ Frequently Asked Questions
Everything you need to know about GST in India
❓ What is GST and how is it calculated?
GST (Goods and Services Tax) is a unified indirect tax system in India that replaced multiple taxes like VAT, Service Tax, and Excise Duty.
Formulas:
GST Amount = (Base Price × GST Rate) ÷ 100
Final Price = Base Price + GST Amount
💰 What are CGST, SGST, and IGST?
GST is divided into three components based on transaction type:
CGST: Central GST (for intra-state) → Central Govt
SGST: State GST (for intra-state) → State Govt
IGST: Integrated GST (for inter-state) → Central Govt
Example: 18% GST = 9% CGST + 9% SGST
🔄 How to calculate GST backwards from final price?
To find base price when you know the GST-inclusive price:
Formula:
Base = Total ÷ (1 + GST Rate/100)
GST = Total - Base
Example: ₹1,180 total with 18% GST
Base = 1,180 ÷ 1.18 = ₹1,000
🏢 Who needs to register for GST?
GST registration is mandatory if:
✓ Annual turnover exceeds ₹20 lakhs (₹10L for special states)
✓ Making inter-state supplies
✓ E-commerce seller/aggregator
✓ Casual taxable person
