What is GST?

GST is an indirect tax levied on the supply of goods and services across India. It replaced a multitude of indirect taxes, including service tax, VAT, and excise duty, streamlining the tax system and reducing complexity. The GST system is multi-stage, comprehensive, and destination-based, meaning it is levied at every point of value addition. By subsuming most indirect taxes, GST has become the primary domestic indirect tax law in India. Also read How to Pay Zero Tax Legally in India

GST Calculation Rules

Calculating GST accurately is essential for compliance and financial health. Here’s a step-by-step guide to calculating GST:

Step 1: Determine the Type of Transaction

• Intra-State Transactions: CGST and SGST are applied equally.
• Inter-State Transactions: IGST is applied.

Step 2: Identify the GST Rate

GST rates vary depending on the type of goods or services. Common slabs are 5%, 12%, 18%, and 28%.

Step 3: Calculate GST Amount

• For Intra-State Transactions: Divide the total GST equally into CGST and SGST.

  • Formula: CGST = (Invoice Value × GST Rate) ÷ 2
  • Example: Invoice Value: ₹10,000, GST Rate: 18%
    • CGST = (₹10,000 × 18%) ÷ 2 = ₹900
    • SGST = ₹900
    • Total GST = ₹1,800

• For Inter-State Transactions: IGST is calculated on the entire transaction value.

  • Formula: IGST = Invoice Value × GST Rate
  • Example: Invoice Value: ₹10,000, GST Rate: 18%
    • IGST = ₹10,000 × 18% = ₹1,800

Step 4: Factor in Input Tax Credit (ITC)

ITC reduces your tax liability by subtracting the GST paid on purchases from the GST collected on sales.

• Formula: Net GST Payable = Output Tax – Input Tax
• Example: Output Tax: ₹20,000, Input Tax: ₹10,000
  • Net GST Payable = ₹20,000 – ₹10,000 = ₹10,000

Step 5: Include Reverse Charge Mechanism (RCM)

For specific transactions, the recipient pays GST under the Reverse Charge Mechanism (RCM).
