📚 Understanding GST in India

What is GST?

GST (Goods and Services Tax) is India's unified indirect tax that replaced multiple taxes like VAT, service tax, excise duty, and others on July 1, 2017. It follows a dual structure — CGST (Central) + SGST (State) for intra-state transactions, and IGST (Integrated) for inter-state transactions.

CGST vs SGST vs IGST

CGST (Central GST): Collected by central government — half of total GST rate for intra-state supply
SGST (State GST): Collected by state government — half of total GST rate for intra-state supply
IGST (Integrated GST): Full GST rate collected by centre for inter-state supply, then shared with the destination state

Example: For 18% GST on an intra-state sale → CGST = 9% + SGST = 9%. For inter-state sale → IGST = 18%.

GST Inclusive vs GST Exclusive

GST Exclusive (Add GST): Price shown is before GST — you add GST on top. Used in B2B transactions and most invoices.
GST Inclusive (Remove GST): Price shown already includes GST — you extract the GST from it. Used in MRP-based retail pricing.

❓ Frequently Asked Questions

Q: How to calculate 18% GST on ₹10,000?

A: GST amount = ₹10,000 × 18% = ₹1,800. Price with GST = ₹11,800. For intra-state: CGST = ₹900 + SGST = ₹900. For inter-state: IGST = ₹1,800.

Q: How to remove GST from a GST-inclusive price?

A: Original Price = GST Inclusive Price ÷ (1 + GST Rate/100). Example: MRP ₹1,180 with 18% GST → Original = ₹1,180 ÷ 1.18 = ₹1,000. GST = ₹180. Use the "Remove GST" mode above.

A: AC restaurants: 5% GST (no ITC). Non-AC restaurants: 5% GST. Outdoor catering: 18%. Alcohol served in restaurants: varies by state (outside GST in most cases). Hotel restaurants where room rate > ₹7,500/night: 18% GST.
