Suppose a person forgot to entered Itc in 3b of July. But he entered this
amount of ITC in may 3b as law also says that he is eligible to take itc of missed invoice before September month's 3b(subsequent year) of annual return of that FY which ever is earlier.
Now my question is there will be mismatch for month of may. So how to deal with this mismatch?
