Note: Any Service Commission or Charge payable in respect of such Online Payments shall be borne by the person making the payments. [For e.g. if a person has to deposit Rs. 10 Lacs as Tax Liability and Rs. 500 are the charges for the transaction, then the person shall be required to bear Rs. 500 as cost and deposit the Full value of Rs. 10 Lacs (Adjusted) to the Government.]

How will the Tax Calculation be worked out?

The Tax liability will be worked out based on the information furnished by the supplier of outward supplies in Form GSTR-3. The following details shall be auto populated from other Forms into GSTR-3

  • ITC Reversal


(Details of inward supplies of taxable goods and/or services effected claiming input tax credit)

Subsequently the Tax Liability will be worked out as a sum of Four Parts in Form GSTR-3 as follows:

  • Tax Liability on Outward Supplies – Shall be auto populated from GSTR-3 as explained above.
  • Tax Liability on Inward supplies on Reverse Charge – Shall be Auto Populated from GSTR-2

Electronic Tax Liability Register shall be an electronic register containing 2 Parts (1 – Electronic Credit Ledger & 2- Electronic Cash Ledger) maintained at the Common Portal which shall contain details of all the amounts payable and paid such as Tax, Interest, Fine, Penalty, etc.

It shall contain Dr (Debit) & Cr (Credit) Columns whereby Dr. against an amount means any amount (Tax, Interest, Penalty) payable on outward supplies including exports or under Reverse Charge. Similarly Cr. Against an amount shall mean any amount paid during the period either by utilizing the Input Credit or through Cash. The payments made under Cash shall also be reflected in GST PMT-1.

Further as per the provisions of Section 49(8) of the GST Act, the amount paid into the Electronic Cash Ledger shall be adjusted as per the manner shown below in the example, irrespective of the details mentioned in the Challan:

Mr. Shiv had the following Output Tax Liability –

For the Month of August, 2017

Tax of Rs. 5,00,000 & Interest of Rs. 15,500

For the Month of September, 2017

Tax of Rs. 3,00,000 & Interest of Rs. 12,500


Now if he Deposits Rs. 7,00,000 into the Account as Tax amount , it shall not be treated entirely as Tax but as follows:



Tax Liability for the Month of August, 2017

Rs. 5,00,000

Interest for the Month of August, 2017

Rs. 15,500

Tax Liability for the Month of September, 2017

Rs. 1,84,500


Rs. 7,00,000
