Common questions

When is CGST + SGST used vs IGST?

CGST + SGST when supplier and recipient are in the same state. IGST when they are in different states or for exports. Same total rate, different split.

What are the GST slabs in India?

0%, 5%, 12%, 18%, 28%. Most services are 18%. Essentials at 5%. Luxury and sin goods at 28%.

Can I claim input tax credit on this?

Yes if you are GST-registered and the invoice has a valid GSTIN. Not for exempt supplies or if the composition scheme applies.
