We had supply under deemed export in month of Oct-17 under notification No. 40/2017 GST Rate is 0.10%.
While entering data in GSTR1 we have entered the same bill in B2B under 18% while editing amount of tax and manually entered @0.05 in CGST & @0.05 in SGST instaed of selecting Deemed Export option.
We have already filed the return.
Now how we will corrected the same transaction in future.
Deemed export correction: GSTR 1 entry errors can be amended in subsequent returns; verify reset or refund options. An entry error in GSTR 1 recorded a deemed export as a regular B2B supply with CGST/SGST instead of selecting deemed export; the return was already filed. Corrections can be made by amending subsequent returns, possibly using a portal reset facility, and by correcting the billing information; the portal presently provides IGST refund options in some cases.
