Exempted sale

For which F.Y you have not reported exempted supply in GST return.?.

Financial year 2021-22

You Can show exempt supply in GSTR9( Table 5) in Annual return F.Y 21-22 , so that  your Income tax and GST  turnover will  tally . 

Dont worry akhilesh.
you show all your turnover in income tax returns.
it wont lead to additional GST payment as non reporting of exempt turnover in gst return does not usually have any impact on gst liability except in case of apportionment of common itc.

you may want to consult some expert about common itc apportionment.
if you had any common itc then it would be better if you didnt show your exempt turnover in itr

Declare such sale in annual return
