🧮 GST Calculation Methods
GST Exclusive Calculation
When price does NOT include GST (tax added on top):
GST Amount = Original Price × (GST Rate ÷ 100)
Total Price = Original Price + GST Amount
Example: Product price ₹1000, GST 18%
GST = ₹1000 × 0.18 = ₹180
Total = ₹1000 + ₹180 = ₹1180
GST Inclusive Calculation
When price ALREADY includes GST (tax is inside the price):
Original Price = Total Price ÷ (1 + GST Rate ÷ 100)
GST Amount = Total Price - Original Price
Example: Total price ₹1180, GST 18%
Original = ₹1180 ÷ 1.18 = ₹1000
GST = ₹1180 - ₹1000 = ₹180

❓ Frequently Asked Questions about GST
- CGST (Central GST): Collected by Central Government on intra-state sales (within same state)
- SGST (State GST): Collected by State Government on intra-state sales
- IGST (Integrated GST): Collected by Central Government on inter-state sales (between states) and imports
For intra-state sales, total GST is split equally as CGST + SGST. For example, 18% GST = 9% CGST + 9% SGST.
Businesses must register for GST if:
- Annual turnover exceeds ₹40 lakhs (₹20 lakhs for special category states)
- For service providers, threshold is ₹20 lakhs (₹10 lakhs for special category states)
- E-commerce operators regardless of turnover
- Businesses making inter-state supplies
- Casual taxable persons and non-resident taxable persons
GST is payable at the time of:
- Supply of goods: When goods are removed from the place of business
- Supply of services: When invoice is issued or payment is received, whichever is earlier
- Continuous supply: When each event of supply occurs
Returns are typically filed monthly (GSTR-3B) by the 20th of next month.
Input Tax Credit means claiming credit for GST paid on purchases. For example:
- You buy raw materials worth ₹1,00,000 paying ₹18,000 GST
- You sell finished goods for ₹1,50,000 charging ₹27,000 GST
- You pay net GST = ₹27,000 - ₹18,000 = ₹9,000 only
ITC prevents tax-on-tax and ensures GST is only on value addition.
- HSN Code (Harmonized System of Nomenclature): Used for goods classification. 2/4/6/8 digit codes for different products
- SAC Code (Service Accounting Code): Used for services classification. 6/8 digit codes for different services
Example: HSN 8517 for mobile phones, SAC 9983 for accounting services.
Penalties for late filing:
- Late fee of ₹50 per day (₹25 CGST + ₹25 SGST)
- For NIL returns, late fee is ₹20 per day (₹10 CGST + ₹10 SGST)
- Maximum late fee is 0.5% of turnover
- Interest at 18% per annum on tax amount
- Revocation of GST registration for prolonged default
📋 GST Composition Scheme for Small Businesses
The Composition Scheme is for small taxpayers with turnover up to ₹1.5 crore (₹75 lakhs for special category states). Benefits include:
✅ Advantages:
- Lower tax rates (1% for manufacturers, 5% for restaurants, 6% for traders)
- Quarterly returns instead of monthly
- Less compliance burden
- No need to maintain detailed records
❌ Restrictions:
- Cannot collect GST from customers
- Cannot claim Input Tax Credit
- Cannot make inter-state supplies
- Cannot supply through e-commerce operators
🚚 E-Invoicing, E-Way Bills & Reverse Charge Mechanism (RCM)
For corporate enterprises and logistics operators, modern GST compliance extends beyond basic invoice arithmetic into digital transaction verification:
📄 Mandatory E-Invoicing (Rule 48(4))
Businesses whose aggregate annual turnover exceeds ₹5 Crore in any preceding financial year must generate an Invoice Reference Number (IRN) and digitally signed QR code through the government Invoice Registration Portal (IRP) for all B2B transactions and export shipments. Invoices issued without valid IRNs are treated as null and void under GST law.
🛣️ Electronic Way Bill (E-Way Bill)
Under Rule 138 of the CGST Rules, consignors must generate an E-Way Bill prior to dispatching any consignment of goods valued at ₹50,000 or above. Part-A records recipient GSTIN and invoice values, while Part-B captures transporter vehicle registration numbers to eliminate tax evasion during inter-state highway transit.
🔄 Reverse Charge Mechanism (RCM)
Under Section 9(3) and 9(4), the statutory liability to pay GST shifts from the supplier to the recipient for notified supplies—such as services rendered by Goods Transport Agencies (GTA), advocate legal representation, sponsorship services, and director fees. Taxes under RCM must be remitted via cash ledger and can subsequently be claimed as Input Tax Credit.
⚖️ Inverted Duty Structure Refunds
When the GST rate levied on raw material inputs is higher than the rate applicable to the finished output goods (such as purchasing fabric at 12% to sell finished garments at 5%), manufacturers accumulate unutilized ITC. Section 54(3) allows eligible enterprises to claim cash refunds of accumulated ITC following prescribed statutory maximum refund formulas.
