What is GSTR3?

GSTR-3 is a monthly return with the summarized details of sales, purchases, sales during the month along with the amount of GST liability. This return is auto-generated pulling information from GSTR-1 and GSTR-2.

Why is GSTR-3 important?

GSTR-3 will show the amount of GST liability for the month. The taxpayer must pay the tax and file the return.

What happens if GSTR-3 is not filed?

If GSTR-3 return is not filed then the GSTR-1 of the next month cannot be filed.  Hence, late filing of GST return will have a cascading effect leading to heavy fines and penalty.

What happens if GSTR-3 is filed late?

If you delay in filing, you will be liable to pay interest and a late fee.Interest is 18% per annum. It has to be calculated by the tax payer on the amount of outstanding tax to be paid. Time period will be from the next day of filing (16th of the month) to the date of payment. Late fee is Rs. 100 per day per Act. So it is 100 under CGST & 100 under SGST. Total will be Rs. 200/day. Maximum is Rs. 5,000.There is no late fee on IGST.

Who should file GSTR-3?

Every registered person is required to file GSTR-3 irrespective of whether there are any transactions during the month or not.However, these registered persons do not have to file GSTR-3–

How to revise GSTR-3?

GSTR-3 once filed cannot be revised. Any mistake made in the return can be revised in the next month’s GSTR-1 and GSTR-2 returns. Direct revision in GSTR-3 is not possible as GSTR-3 is auto-generated without provision for editing.

How will GSTR-3 and GSTR-3B be reconciled?

GSTR 3B is a simple return form introduced by the CBEC for the month of July and August 2017. GSTR-3 will also have to be filed for July & August 2017.On filing the GSTR 3, if actual liabilities are different from those declared in GSTR 3B, the system will update the (difference) between GSTR 3B and GSTR 3 automatically. In case, actual liabilities in GSTR-3 are higher than those declared and paid with GSTR-3B, you will have to pay the extra amount tax along with interest on the extra amount.

Note: GSTR-3 must be filed only after paying entire tax liability otherwise it will not be treated as valid return.If taxpayer has filed an invalid return and later on he wants to pay the remaining liability then he has to file the Part B of GSTR-3 again.

This will contain the changes made to your sales invoice. If the amount is changed, the amount of ITC to claim also changes which impacts the tax payable to the government.

This heading will contain the mismatches in ITC and tax liability between the original returns and any changes filed during the current month. This information will be sourced from GSTR-2.

a. ITC claimed on mismatched or duplication of invoices or debit notes:  In case mismatch of invoices, there may be double claiming of ITC. The excess ITC claimed from duplicate purchase invoices will be reversed and added to the tax liability.

b. Tax liability on mismatched credit notes: Incorrect credit notes issued by you will also result in incorrect ITC. Extra ITC claimed due to mismatch will now be added to your tax liability.

c. Reclaim on rectification of mismatched invoices/Debit Notes: This is the opposite of point (a). In this case, mismatch has led to claiming lower ITC. You are entitled to more ITC and so the additional amount will be reduced from the output tax liability.

d. Reclaim on rectification of mismatch credit note: (Reduce): This is opposite to (b), i.e., lower ITC has been claimed and will work in the same way as (c).

e. Negative tax liability from previous tax periods: This is due to excess tax paid during the previous months and will be reduced from output tax liability of this month.

f. Tax paid on advance in earlier tax periods and adjusted with tax on supplies made in current tax period. This refers to tax paid along with advance payments in earlier months for supplies received during this month.

8C. On account of ITC reversal or reclaim: This is the additional tax payable/or reduction available due to ITC reversal or reclaim. The information flows from Table 11 of GSTR-2.

8D. On account of mismatch/ rectification /other reasons: This will include tax liability due to any other reason.

9. Credit of TDS and TCS

This heading will contain the details of TDS and TCS paid by you. The amounts of TDS/TCS will be deducted from the total liability to arrive at net tax amount you must pay.

10. Interest liability (Interest as on ..)

Interest is applicable on delay of payment. Interest is 18% per annum. It has to be calculated by the tax payer on the amount of outstanding tax to be paid. The time period will be from the next day of filing (20th of the month) to the date of payment. This heading shows the reason and the amount of interest applicable. Breakup into CGST, SGST, IGST & Cess will be given.

  • Output liability on mismatch: Your tax liability has increased due to a change in the sales invoice and you must pay interest on the increased amount
  • ITC claimed on mismatch invoice: Your tax liability has increased due to a change in the purchase invoice and ITC was claimed on such invoice. You must pay interest on the increased amount.
  • On account of other ITC reversals: Your ITC claimed was reversed which has increased your tax liability and so interest is payable.
  • Undue excess claims or excess reduction [refer sec 50(3)]: You have claimed extra ITC and now you are required to pay interest
  • The credit of interest on rectification of mismatch: You had paid interest on the mismatch and now the interest is reversed or credited back.
