Dear Sir,
Q1. Can I issue a debit note in May 2019 for invoice pertaining to F.Y 2017-18:- CAN ISSUE
Reply:- There is no time limit prescribed in the Act for issuing debit note.(Time limit is prescribed only for issuance of credit note u/s 34 of CGST Act) You can issue a debit note in May 2019 for invoice pertaining to F.Y 2017-18
Q.2 Can the recipient avail the Input Tax Credit(ITC):- (CANNOT AVAIL ITC)
Reply:- For availment of ITC, time limit has been prescribed under the law vide section 16(4) of CGST Act extract of which is provided below:-
"A registered person shall not be entitled to take input tax credit in respect of any invoice or debit note for supply of goods or services or both after the due date of furnishing of the return under section 39 for the month of September following the end of financial year to which such invoice or invoice relating to such debit note pertains or furnishing of the relevant annual return, whichever is earlier."
However, for F.Y 2017-18 the time limit for availment of ITC been extended vide RoD no.02/2018 - central tax dated 31st December 2018 till due date of filing March 2019 returns subject to conditions that the details of the transactions has been uploaded by the supplier in his GSTR-1. Being the time limit expired, the ITC cannot be availed by recipient.
Summarising the reply for Q.1 & Q.2 the supplier can issue debit for an invoice whenever he wants but the recipient can avail the ITC only till the time limit prescribed u/s 16(4) of CGST Act.
Q.3 Would interest be applicable for liability arising through issuance of debit note:- (NO INTEREST)
Reply:- In terms of Section 12 & 13 of CGST Act - "time of supply" the Explanation 1 provides that “supply shall be deemed to have been made to the extent it is covered by the invoice or, as the case may be, the payment"
Since the time of supply covers only to the extent covered vide invoice, the value of debit note may not be linked to the time of supply of original invoice for the purpose of interest calculation as the liability arises when the debit note issued. In your case the liability pertains to May 2019 and you required to pay interest only when you delay in making payment within the due date of May 2019.
Note:- There is no time of supply prescribed for debit note - we can treat the debit note as invoice for the purpose of ariving time of supply. However, this treatment may not hold good when there is a different rate of tax as on the date of issuance of invoice and issuance of debit. In that case as per the logic the rate of tax has to be determined as per the date of original invoice.
