Understanding GST
GST (Goods and Services Tax) is an indirect tax levied on supply of goods and services in India. It replaced multiple indirect taxes like VAT, Service Tax, and Excise Duty.
GST Structure
- CGST: Central GST โ goes to Central Government
- SGST: State GST โ goes to State Government
- IGST: Integrated GST โ for inter-state transactions
- UTGST: Union Territory GST โ for Union Territories
Intra-State vs Inter-State
Intra-State (Within Same State):
- Example: Mumbai seller โ Pune buyer (both Maharashtra)
- GST splits equally: CGST 9% + SGST 9% = 18%
Inter-State (Between States):
- Example: Mumbai seller โ Delhi buyer
- Single tax: IGST 18%

GST Calculation Examples
Example 1: Add GST (Exclusive)
- Product Price: โน10,000
- GST Rate: 18%
- GST: โน10,000 ร 18% = โน1,800
- CGST: โน900 | SGST: โน900 (intra-state)
- Total Invoice: โน11,800
Example 2: Remove GST (Inclusive)
- Total Amount: โน11,800 (GST included)
- GST Rate: 18%
- Base: โน11,800 รท 1.18 = โน10,000
- GST: โน11,800 โ โน10,000 = โน1,800
Input Tax Credit (ITC)
- Concept: GST paid on purchases can be claimed as credit against output tax
- Benefit: Eliminates tax-on-tax cascading effect
- Example: Bought goods for โน10K + โน1.8K GST โ ITC โน1.8K available
GST Registration
- Mandatory: Turnover > โน40L (goods) or > โน20L (services)
- GSTIN: 15-digit unique registration number
- E-way Bill: Required for goods > โน50K
- Returns: GSTR-1, GSTR-3B monthly or quarterly
Common GST Mistakes
- โ Confusing GST inclusive vs exclusive prices in quotes
- โ Using CGST+SGST for inter-state sales (should be IGST)
- โ Not claiming Input Tax Credit (ITC)
- โ Missing e-way bill for goods > โน50K
- โ Late GST return filing (penalty โน50/day, max โน5,000)
Pro Tips
- Always clarify GST inclusive/exclusive in invoices and quotations
- Maintain proper tax invoices for claiming ITC
- Verify GSTIN of suppliers on the GST portal before claiming ITC
- File returns on time โ late fees compound quickly
