When buyer and seller are in the same state, GST is split equally between Centre (CGST) and State (SGST). Each gets half the applicable rate.
When goods/services cross state boundaries, the full GST is levied as IGST by the Centre. It's later distributed between Centre and the destination state.
GST paid on purchases (inputs) can be claimed as ITC and set off against GST liability on sales — reducing the effective tax burden.
