Frequently Asked Questions

Q: What is the difference between CGST, SGST, and IGST?

CGST (Central GST): Collected by Central Government on intra-state sales

SGST (State GST): Collected by State Government on intra-state sales

IGST (Integrated GST): Collected by Central Government on inter-state sales

For 18% GST in Maharashtra: 9% CGST + 9% SGST. For Delhi to Maharashtra: 18% IGST

Q: How to calculate GST for multiple items with different rates?

Calculate tax for each item separately using its applicable rate, then sum up all taxes. Use our calculator multiple times for different rates or use a spreadsheet for bulk calculations.

Q: Is GST applicable on exports and imports?

Exports: Zero-rated (0% GST), eligible for Input Tax Credit refund
Imports: IGST is levied, treated as inter-state supply. Customs duty + IGST applicable.

Q: What is Input Tax Credit (ITC) in GST?

ITC allows businesses to reduce tax paid on inputs from tax payable on outputs. If you paid ₹1,000 GST on purchases and collected ₹2,000 GST on sales, you pay only ₹1,000 (₹2,000 - ₹1,000) to government.
