How is GST calculated?

GST = (Base × Rate) / 100. To remove GST from an inclusive price: Base = Amount × 100 / (100 + Rate).

CGST vs SGST vs IGST?

For sales within the same state, GST is split equally between CGST (Centre) and SGST (State). For inter-state sales, the entire GST is IGST.

Do freelancers need GST?

If your annual turnover exceeds ₹20 lakh (₹10 lakh in special states) or you provide inter-state services, GST registration is required.

Which GST rate applies to services?

Most professional and freelance services fall under the 18% GST slab, but check the exact HSN/SAC code for your service.
