Understanding GST in India
The Goods and Services Tax (GST) is a comprehensive indirect tax levied on the supply of goods and services in India, operating on a "One Nation, One Tax" philosophy.
GST Tax Slabs & Variations
Standard GST slabs are 5%, 12%, 18%, and 28%. However, these rates are not universal. Essential items like basic food grains are exempt (0%), while luxury goods or sin goods attract 28% plus additional cess. Always verify the current rate applicable to your specific product/service using its HSN/SAC code.
How to Calculate GST
1. Adding GST (Exclusive Price)
When the price is given without GST, and you need to add it:
- GST Amount = (Base Price × GST Rate) / 100
- Total Price = Base Price + GST Amount
2. Extracting GST (Inclusive Price)
When the price already includes GST (like the MRP of a laptop), and you need to find the base value:
- Base Price = (Total Price × 100) / (100 + GST Rate)
- GST Amount = Total Price - Base Price
CGST, SGST, and IGST
How GST is split depends on whether the transaction crosses state borders.
- Intra-state (Within the same state): GST is divided equally into CGST (Central GST) and SGST (State GST). Example: An 18% tax becomes 9% CGST + 9% SGST.
- Inter-state (Between two different states): A single IGST (Integrated GST) is charged. Example: Full 18% IGST.
Input Tax Credit (ITC) and RCM
ITC: Businesses can claim credit for the GST they paid on purchases against the GST they collect on sales. This prevents the cascading "tax-on-tax" effect.
RCM (Reverse Charge Mechanism): Usually, the supplier collects and pays GST. Under RCM, the buyer is legally responsible for depositing the tax directly to the government (common in freight transport and legal services).
