All are consumption taxes collected at each stage of the supply chain with input tax credit.

❓ Frequently Asked Questions

What are the new GST slabs in India 2026? ▾

After the GST 2.0 reform effective September 22, 2025, India now has: 0% (exempt essentials — dairy, medicines, fresh food), 5% (essential goods — packaged foods, basic household items, healthcare services), 18% (standard rate — electronics, most services, consumer goods), 40% (luxury and sin goods — premium cars, tobacco, aerated drinks). Gold and gems remain at 3%. The old 12% and 28% slabs are removed.

How to calculate 18% GST? ▾

To add 18% GST: multiply base price by 1.18. Example: ₹1,000 × 1.18 = ₹1,180 (GST = ₹180). To remove from MRP: divide by 1.18. Example: ₹1,180 ÷ 1.18 = ₹1,000. CGST = 9%, SGST = 9% for intra-state sales.

What is the difference between CGST, SGST, and IGST? ▾

For intra-state sales (within same state): GST splits equally — CGST (Central) + SGST (State). For 18% GST: CGST = 9%, SGST = 9%. For interstate sales: IGST = 18% goes entirely to the Centre and is later apportioned. Toggle "Interstate Sale" in our calculator to see IGST breakdown.

Is GST included in MRP? ▾

Yes. In India, MRP always includes GST. Use the "Remove GST" option to find the base price before tax. Example: If MRP is ₹590 with 18% GST, base price = ₹590 ÷ 1.18 = ₹500.

What happened to 12% and 28% GST slabs? ▾

The 56th GST Council meeting on September 3, 2025 merged these slabs under GST 2.0. Most items previously at 12% moved to 5% or 18%. Most 28% items moved to 18% or the new 40% luxury rate. You can still enter 12% or 28% as a custom rate for transitional use cases.
