Understanding Indian GST Slabs & Rules
1
Intra-State vs Inter-State
If buying/selling within the same state, GST is split equally into CGST (Central) and SGST (State). For outside state supply, IGST applies.
2
GST Inclusive vs Exclusive
GST Exclusive adds tax on top of your base price. GST Inclusive extracts the hidden tax component from the MRP or billed total.

Commercial Services (18%)
Most cyber cafe services, photography, online application processing, and computer services fall under the standard 18% slab.
