But now the problem is that if you are filing NIL return then there is message showing ” You have no summary to submit GSTR1.
So the solution is very simple open all columns and without adding any invoice click on back button.
After that submit the detail and choose your option of “DSC” or “EVC” to file GSTR 1 NIL return.
It will let you submit NIL return without any problem.
Check step by step procedure given below by images:
Step 1: Click on B2B Column.
Step 3: Do same procedure with all columns like B2c, export and all except on 10th Column “Nil Rated Supplies”
Step 4: On 10th Column, click on save and then back.
Step 4: After that submit and file return with DSC or EVC option.
Hope it will solve your problem of submitting GSTR 1 Nil return without any error.
