Frequently Asked Questions

How do I calculate GST on a price?+
For GST exclusive (adding GST): GST Amount = Price × Rate ÷ 100. Total = Price + GST Amount. For GST inclusive (extracting GST): Base = Total × 100 ÷ (100 + Rate). GST = Total − Base.
What is the difference between CGST, SGST and IGST?+
CGST (Central GST) and SGST (State GST) are each charged at half the applicable GST rate on intra-state transactions. IGST (Integrated GST) is charged at the full rate on inter-state transactions and imports.
What are the current GST slabs in India?+
India has four primary GST rate slabs: 5%, 12%, 18%, and 28%. Certain goods attract special rates — 0%, 0.1%, 0.25%, and 3% — such as fresh food, rough diamonds, and gold.
What is a GSTIN and how is it structured?+
GSTIN is a 15-character alphanumeric identifier. Positions 1-2 are the 2-digit state code, 3-12 are the taxpayer's PAN, 13 is the entity registration number within the state, 14 is always Z, and 15 is a checksum digit.
What is the difference between GST inclusive and GST exclusive price?+
GST exclusive means the listed price does not include GST — tax is added on top. GST inclusive means the listed price already includes GST, and the base price needs to be extracted.
