Frequently Asked Questions

What is GST?

GST (Goods and Services Tax) is an indirect tax levied on the supply of goods and services in India. It has replaced multiple indirect taxes like VAT, excise duty, and service tax.

What are the different GST rates in India?

India has multiple GST slabs: 0% (essential items), 5% (basic necessities), 12% (processed foods), 18% (standard rate for most goods), and 28% (luxury and sin goods).

When should I use "Add GST" vs "Remove GST"?

Use "Add GST" when you have a base price and need to calculate the final price including GST. Use "Remove GST" when you have a GST-inclusive price and need to find the base amount and GST component.

How to calculate GST manually?

To add GST: Total = Base Amount × (1 + GST Rate/100). To remove GST: Base = Total ÷ (1 + GST Rate/100), GST = Total - Base. Our calculator does this instantly for you.

What is CGST and SGST?

CGST (Central GST) and SGST (State GST) are components of GST on intra-state transactions. They split equally - for 18% GST, CGST is 9% and SGST is 9%. For inter-state, IGST applies at the full rate.

Do I need to register for GST?

GST registration is mandatory if your annual turnover exceeds ₹40 lakhs (₹20 lakhs for service providers in most states). Some states have ₹20 lakh threshold for goods too. E-commerce sellers must register regardless of turnover.

Which GST rate applies to my product?

GST rates vary by product category: 5% for essential items, 12% for processed foods, 18% for most goods and services, 28% for luxury items. Check the GST Council's HSN/SAC code classification for your specific product or service.
