Second proviso u/s 16 (2) (d) of the CGST Act, 2017 says that such ITC (i.e. where value of supply along-with taxes are not paid to the supplier within 180 days from date of invoice) will be added to recipient-assessee's output tax liability, along with interest thereon, in such manner as may be prescribed.
Said rule 37 (1) of the CGST Rules, 2017 prescribes recipient-assessee to disclose specified details for such ITC in Form GSTR-2.
And sub-rule (2) thereunder states that 'The amount of input tax credit referred to in sub-rule (1) shall be added to the output tax liability of the registered person for the month in which the details are furnished.' And sub-rule 3 states that 'The registered person shall be liable to pay interest at the rate notified under sub-section (1) of section 50 for the period starting from the date of availing credit on such supplies till the date when the amount added to the output tax liability, as mentioned in sub-rule (2), is paid.'
It is almost now certain that Form GSTR-2 will never see light of the day.
In this background, questions which comes to my mind are these:
A. Where an recipient-assessee is required to add such ITC amount to its output liability while filing Form GSTR-3B?
B. Does such disclosure is mandatory in Table 4 (b) (2) of Form GSTR-3B and if yes, on what is the legal basis to back such claim?
B. And absence of availability of prescribed manner to disclose such events (i.e. in Form GSTR-2), why assessee is required to do anything to comply with second proviso u/s 16 (2) (d) of the CGST Act, 2017? And where is question of paying any interest?
In above background, I would argue that there is nothing under current law & rules - as of now - which compels the recipient-assessee to anything about such ITC availed (i.e. where value of supply along-with taxes are not paid to the supplier within 180 days from date of invoice).
Please treat these comments more from point of brain-storming among professions.
