Hi, can anyone guide me what will be the next course of action if there is a mistake in filing the gstr 9 table 6 where in the itc claimed has been wrongly put as 0 when in 3 B we have taken the credit. The client has filed gstr 9 without updating table 6 option b. Can this mistake be rectified in GSTR 9c ? What is the next course of action to be taken.
