Now, coming back to my earlier post at Serial no. 6 above. Please note the followings:
1. Revised Section 50 (3) of the CGST Act, 2017 (amended retrospectively w.e.f. 01.07.2017) reads as follows:
"Where the input tax credit has been wrongly availed and utilised, the registered person shall pay interest on such input tax credit wrongly availed and utilised, at such rate not exceeding twenty-four per cent. as may be notified by the Government, on the recommendations of the Council, and the interest shall be calculated, in such manner as may be prescribed."
2. sub-rule (3) of Rule 88 B reads as follows:
"In case, where interest is payable on the amount of input tax credit wrongly availed and utilised in accordance with sub-section (3) of section 50, the interest shall be calculated on the amount of input tax credit wrongly availed and utilised, for the period starting from the date of utilisation of such wrongly availed input tax credit till the date of reversal of such credit or payment of tax in respect of such amount, at such rate as may be notified under said sub-section (3) of section 50.
Explanation. -For the purposes of this sub-rule, -
(1) input tax credit wrongly availed shall be construed to have been utilised, when the balance in the electronic credit ledger falls below the amount of input tax credit wrongly availed, and the extent of such utilisation of input tax credit shall be the amount by which the balance in the electronic credit ledger falls below the amount of input tax credit wrongly availed.
(2) the date of utilisation of such input tax credit shall be taken to be, -
(a) the date, on which the return is due to be furnished under section 39 or the actual date of filing of the said return, whichever is earlier, if the balance in the electronic credit ledger falls below the amount of input tax credit wrongly availed, on account of payment of tax through the said return; or
(b) the date of debit in the electronic credit ledger when the balance in the electronic credit ledger falls below the amount of input tax credit wrongly availed, in all other cases."
3. “input tax credit” means the credit of input tax, as per Section 2 (63) of the CGST Act, 2017.
4. Relevant portion of Section 2 (62) of the CGST Act, 2017 reads as follows:
"“input tax” in relation to a registered person, means the central tax, State tax, integrated tax or Union territory tax charged on any supply of goods or services or both made to him and includes– ................. ........................"
5. Your attention is also invited to Section 49 (2) read with Section 41, 2 (46) of the CGST Act, 2017 & Rule 86 of the CGST Rules, 2017 .
6. There are some rules (For example: Rule 44 (2)) which requires "separate" calculations for input tax credit of central tax, State tax, Union territory tax and integrated tax, but Rule 88B (3) does not put any such conditions.
7. In view of above read with fact of your case, I had shared my ex-facie views in post at serial no. 6 above.
These are ex facie views of mine and the same should not be construed as professional advice / suggestion.
