Frequently Asked Questions

How do I calculate GST on a product?

GST Amount = Base Price × GST Rate. For ₹1000 product at 18% GST: ₹1000 × 0.18 = ₹180 GST. Total invoice = ₹1180. Split equally into CGST and SGST for intra-state sales.

What is the difference between GST-inclusive and exclusive pricing?

Exclusive: GST added on top (₹1000 + 18% = ₹1180). Inclusive: GST included in shown price (₹1180 contains ₹180 GST). Calculate from inclusive: GST = Price × Rate ÷ (100 + Rate).

How do I claim Input Tax Credit (ITC)?

ITC = GST paid on purchases used for business. Claim against GST liability on sales. Net payable = Output GST - Input GST. Keep proper invoices and ensure supplier compliance for valid ITC.

When is IGST charged instead of CGST/SGST?

IGST applies to inter-state transactions (buyer and seller in different states) and imports. It equals the full GST rate. CGST+SGST (each half the rate) apply to intra-state transactions.

What GST rate applies to my product?

Rates: 0% (essentials), 5% (essential goods), 12% (processed food, computers), 18% (most goods/services), 28% (luxury items). Check the HSN code for exact classification of your product.
