nothing to worry enter less sales in April month gstr3b and file but you file correctly gstr3b 1 for March and April gstr3b is not the final return so don't worry gstr 1 is the final so whatever mistake you done is gstr3b for March you adjust the same in April
is there any notification regarding the above answer because i talked with gst help center and they said that is is not allowed to reduce the april sales figures if more sale has been ahowed in march gstr3b return
sorry to say but i didnt get your idea. do you mean to say that when i file gstr1 for 4th quater i must show actual sales bill, and when i file gstr3b for april month i should less the original sale and tax for april month. and file gstr1 for april with actual sales figures and bills
