Frequently Asked Questions

 

1. What are the basic GST and TDS compliance obligations for taxpayers?

Basic GST compliance includes proper registration, issuing tax invoices, maintaining records, paying tax on time, and filing applicable GST returns. TDS compliance includes deducting tax at the prescribed rate, depositing it within due dates, filing TDS returns, and issuing certificates.

2. What if I fail to meet the GST compliance due dates of GSTR-1 yet tax has already been paid under GSTR-3B?

Invoice reporting is not in place of tax payment. Even when there are missed GST compliance due dates of GSTR-1, there may still be an imposition of late fees, lack of match in sales reporting and the department may issue follow-up notices.

3. Does IFF have to be made under QRMP in case I would prefer my B2B customer to claim ITC prior to quarter-end?

IFF is not compulsory but in most instances it assists. Unless you upload B2B invoices via IFF within the initial two months, your customer will be required to wait until quarterly GSTR-1 is submitted to obtain credit.

4. Is IFF mandatory under QRMP if my B2B customer wants to claim ITC early?

IFF is optional under QRMP, but it can be used to report B2B invoices so that your customers can claim Input Tax Credit (ITC) without waiting for the quarterly GSTR-1.

5. Can GST returns be revised if I have entered the wrong invoice value in GSTR-1?

No. GST returns cannot be revised like Income Tax Returns. Corrections usually need to be made in a subsequent return within the permitted time limit under GST law.

6. Do I need to pay late fees if my sales are nil but I missed the GST filing due date?

Yes, late fees are applicable even if there is no tax liability. Nil returns generally attract lower late fees, but timely filing is still mandatory.

7. At what time is ITC-04 important to job work transactions?

ITC-04 is relevant when materials are shipped to or shipped back to a job worker. Unless it is reported appropriately, a department might raise an issue of how goods were moved during assessment or verification.

8. Is it possible to submit GSTR-9 when one (or two) monthly returns are outstanding?

Usually no. Prior to the filing of the annual return, monthly or quarterly related returns should be usually filed before the annual return. Annual reconciliation can be problematic due to pending returns.

9. What can Ebizfiling do when I have already missed several GST compliance due dates?

Ebizfiling assists you to verify the returns to be submitted, exposure to late fee, and the appropriate order of filing the returns to ensure that the backlog is cleared accordingly.

10. Can Ebizfiling assist me to know the due dates of the GST compliance to my business?

Yes. Regardless of whether you are on the regular scheme, QRMP or composition scheme, Ebizfiling can assist in mapping the appropriate dates on which the GST compliance must be made to ensure that you do not follow the wrong calendar of filing.
