Issue credit note of differential CST duty.No need to change the original invoice also u had filed ur cst return taking into consideration of full rate.

AI Summary

CST adjustment: issue a credit note for differential tax; original invoice need not be amended.
Advisory: where full CST was charged and returns filed, do not amend the original invoice on receipt of concessional Form C; instead issue a credit note for the differential CST to adjust tax liability while keeping the original dispatched invoice intact.
