    How can i enter the sales made to unregistered buyers… Whether I required to enter every invoice or aggregate of all sales made and liabilities accrued

  2. P L Shrivastav says:

    I entered in ITC column all credit in IGST that was wrong, as it consist all IGST, CGST and SGST. But i realised this after submitting the GSTR3B. As there was no option to edit, utilize the credit in the same way, first against IGST, then CGST and then SGST. Actual payable was coming in IGST so challan was paid in IGST, but now after adjustment payable was coming in SGST. It allowed to adjust IGST cash payment in SGST. I got the message of successful of setoff adjustment. But while going to file with DSC, it is showing error message, first clear due and then file return, i then paid SGST, then IGST and then also one challan practically generated for Rs. 2.00, But still facing problem as getting the same error.

    I just want to ask the GST department,
    1. Why there is no edit option after submitting the data. As payment adjustment is showing only after submitting the data.
    2. As GST is new return, why it is online, why not offline, like MVAT form.
    3. Why there is no toll free number for GST help line, why STD call number is given?

  3. Yogesh K says:

    Nice article. Please clarify about the treatment of invoices for pre GST period ( i.e. Excise & VAT ) but accounted for in July-17 as June-17 VAT Return & payment is already submitted.

  4. Asish Abraham says:

    Are you sure that additional liability arising on filing GSTR-1 compared to the figures in GSTR-3B will yield interest liability? Wasn’t there an interest exemption for the months of july & august returns even if there is a difference in the individual returns filed as compared to the GSTR-3B?

  5. R S Sengar says:
