Frequently Asked Questions
How to calculate GST in India?
To add GST: GST Amount = Base Price × GST Rate ÷ 100. Total = Base Price + GST Amount. To remove GST from MRP: Base Price = Total Price × 100 ÷ (100 + GST Rate).
What is the difference between CGST, SGST, and IGST?
For intra-state sales (buyer and seller in same state): GST splits into CGST (goes to central govt) and SGST (goes to state govt) — each at half the GST rate. For inter-state sales: IGST (full GST rate) is charged, which the central government then distributes.
Is GST applicable on all services?
Most services attract 18% GST. Exemptions include healthcare, education, and certain financial services. Software services attract 18% GST. Export of services is zero-rated (0% GST, but ITC can be claimed).
How to file GST returns in India?
File GSTR-1 (outward supplies) by 11th of each month. File GSTR-3B (summary return + payment) by 20th/22nd/24th. Annual return GSTR-9 by December 31. Use GST portal (gst.gov.in) or accounting software like ERPNext.
