Understanding Indian GST Structure: CGST, SGST & IGST

The Goods and Services Tax is categorized based on the geographic location of the buyer and seller:

  • Intra-State Transactions: When the supplier and recipient reside within the same state or union territory, the tax is split equally into Central GST (CGST) and State GST (SGST) or UTGST. For instance, an 18% GST rate consists of 9% CGST and 9% SGST.
  • Inter-State Transactions: When goods or services cross state borders, or during international imports, Integrated GST (IGST) is levied as a single unified tax amount.

Standard GST Slabs in India

The GST Council categorizes commodities into four primary rate slabs:

  • 0% (Exempt): Essential unbranded food grains, milk, fresh vegetables, educational services, and healthcare.
  • 5%: Mass consumption items, packaged foods, apparel below ₹1,000, and economy transportation.
  • 12%: Processed foods, business class air tickets, and standard manufactured items.
  • 18%: Most commercial services, software development, IT consulting, telecom, and consumer durables.
  • 28%: Luxury goods, motor vehicles, aerated drinks, and sin goods.

Frequently Asked Questions (FAQ)

To add GST: multiply the base amount by the GST rate and divide by 100. For example, 18% GST on ₹1,000 is (1,000 × 18) / 100 = ₹180, giving a total of ₹1,180.

To remove GST from an inclusive figure: Base Price = (Total Inclusive Price × 100) / (100 + GST Rate). For ₹1,180 with 18% GST, Base = (1,180 × 100) / 118 = ₹1,000. The GST component is ₹180.

Under Section 15 of the CGST Act, trade discounts shown on the invoice are deducted first from the list price. GST is calculated strictly on the net discounted taxable value.
