GST (Goods and Services Tax) is India's unified indirect tax that replaced a complex web of 17 different taxes in July 2017. It's a destination-based, multi-stage tax applied at every point of sale — but only on the value added at each stage, not the full price.
For consumers, GST is straightforward — you pay a fixed percentage on your purchase. For businesses, GST comes with the powerful Input Tax Credit (ITC) mechanism — you can claim back GST paid on your purchases against GST collected on your sales, paying only the net difference to the government.
The GST Formulas
➕ Adding GST (exclusive price → inclusive price):
GST Amount = Original Price × (GST Rate / 100)
Total Price = Original Price + GST Amount
➖ Removing GST (inclusive price → exclusive price):
Original Price = Inclusive Price ÷ (1 + GST Rate/100)
GST Amount = Inclusive Price − Original Price
🏙️ CGST + SGST split (intra-state):
CGST = GST Amount ÷ 2 · SGST = GST Amount ÷ 2
| Tax | Full Form | When Applied | Goes To | Rate (18% GST) |
|---|---|---|---|---|
| CGST | Central GST | Intra-state sales | Central Govt. | 9% |
| SGST | State GST | Intra-state sales | State Govt. | 9% |
| IGST | Integrated GST | Inter-state / imports | Central Govt. (shared) | 18% |
Input Tax Credit (ITC) can save you thousands
GST-registered businesses can claim back GST paid on purchases. If you paid ₹18,000 GST on raw materials and collected ₹36,000 GST on sales, you only pay the net ₹18,000 to the government. Keep your invoices!
GST registration mandatory above ₹40L turnover
Businesses with annual turnover above ₹40 lakh (₹20L for services, ₹10L for special states) must register for GST. Voluntary registration is allowed below this threshold to claim ITC.
GSTR-3B is due monthly/quarterly
Regular taxpayers file GSTR-3B monthly by the 20th. Businesses under the Quarterly Return Monthly Payment (QRMP) scheme file quarterly. Late filing attracts ₹50/day penalty (₹20 for nil return).
A valid GST invoice must have specific fields
For ITC claims, your purchase invoice must have: supplier's GSTIN, HSN/SAC code, invoice number, date, tax amount split (CGST/SGST or IGST), and buyer's GSTIN. Missing fields can lead to ITC rejection.
Composition scheme: lower rate, no ITC
Small businesses (turnover up to ₹1.5 Cr) can opt for the Composition Scheme — pay 1–6% flat GST without the hassle of monthly returns. But you cannot claim ITC and cannot make inter-state sales.
