Frequently Asked Questions

How do I add GST to a price in India?+
Multiply the base price by the GST rate and add it: Total = Base × (1 + Rate/100). For ₹10,000 at 18% GST → ₹10,000 × 1.18 = ₹11,800. For intra-state, the GST splits equally into CGST + SGST (9% + 9%). For inter-state, the full 18% applies as IGST.
How do I remove GST from an inclusive price?+
Use: Base = Inclusive ÷ (1 + Rate/100). For ₹11,800 at 18% → ₹11,800 ÷ 1.18 = ₹10,000. GST component = ₹11,800 − ₹10,000 = ₹1,800. This is also called reverse charge calculation.
What are the GST slabs in India 2026?+
India has five GST rate categories: 0% (essential exempt goods), 5% (essential goods — edible oil, sugar, spices), 12% (processed foods, computers), 18% (most services — IT, telecom, restaurants), and 28% (luxury/sin goods — cars, tobacco, aerated drinks).
What is the difference between CGST, SGST and IGST?+
For intra-state transactions, GST splits equally: CGST (Central GST, goes to Government of India) + SGST (State GST, goes to state government), each at half the rate. For inter-state or import transactions, the entire GST applies as IGST (Integrated GST), which the Centre later divides with states.
Do I need GST registration to use this calculator?+
No — this calculator is free with no registration needed. However, if your annual turnover exceeds ₹40 lakh (₹20 lakh for services, ₹10 lakh for special category states), GST registration is mandatory. ClearlyComply offers GST registration from ₹999 with CA support.
How is GST calculated for composition scheme dealers?+
Composition dealers pay GST at flat rates on turnover: 1% (traders), 5% (restaurants), 6% (manufacturers). Composition dealers cannot charge GST on invoices or claim ITC. This calculator covers the standard GST regime only.
