FAQ
Common questions
What are the GST slabs now?
From 22 September 2025: 0%, 5% and 18% for most items, 40% for sin and luxury goods; 3% for gold/silver; a few legacy 12%/28% items remain in transition.
CGST/SGST or IGST?
Same state as the buyer: CGST + SGST (half each). Different state, SEZ or import: IGST at the full rate.
Is this tax advice?
No — it is arithmetic. Your CA or the CBIC rate finder decides the applicable rate.
