Now as per CGST Amendment act 2018 Prescribed the New rule for Utilization of ITC as Given in Sec 49A
49A. Notwithstanding anything contained in section 49, the input tax credit on account of central tax, State tax or Union territory tax shall be utilised towards payment of integrated tax, central tax, State tax or Union territory tax, as the case may be, only after the input tax credit available on account of integrated tax has first been utilized fully towards such payment.
Now the confusion arises the CGST Amendment act was made applicable from 1st Feb 2019 but the GST Portal showed the Old rule for utilization of ITC Under Sec 49 rather than 49A
Gst council have now decided to defer the applicability of the new rule, as per Notification No. 13/2019 Central Tax Dated 07.03.2019 Extract
“2. Payment of taxes for the discharge of tax liability as per FORM GSTR-3B.– Every registered person furnishing the return in FORM GSTR-3B of the said rules shall, subject to the provisions of section 49 of the said Act, discharge his liability towards tax, interest, penalty, fees or any other amount payable under the said Act by debiting the electronic cash ledger or electronic credit ledger, as the case may be, not later than the last date, as specified in the first paragraph, on which he is required to furnish the said return. “
So as per the above notification, we have to discharge the liability of tax as per the old rule given in Sec 49 of CGST Act, 2018.
