However, not performing reconciliation between GSTR1 and GSTR 3B can result in a show-cause notice from the GST authorities. Moreover, you may not be able to file an accurate Annual GST Return due to the mismatches.

Here in this article we'll provide details of what is GSTR 1 and what is GSTR 3B:

1. What is GSTR1 and GSTR 3B?

GSTR 3B is a summary return filed by a taxpayer on a monthly basis. Furthermore, GSTR 3B is to be filed by the 20th day of the next month.

GSTR 3B shows supplies during the month together with GST paid, Input Tax Credit availed, and reverse charge purchases etc. Now, you understand what is GSTR 3B.

On the other handa reporting return is GSTR 1GSTR 1 is a monthly/quarterly return that shall be filed by taxpayers. Before the GSTR 1 deadline business details for outward supplies must be submitted on form GSTR 1. Before the GSTR 1 deadline business details for outward supplies must be submitted on form GSTR 1. GSTR 1 helps in disclosing details of monthly/quarterly sales and tax liability.

2. Importance of Reconciliation Between GSTR1 and GSTR 3B

Reconciling Form GSTR1 and 3B plays an important role as it helps in the following manner:

  • It ensures that there is no duplicity or omission of invoices
  • This helps in arriving at an accurate amount of tax that is payable on the sales during the specified period
  • It assists in identifying errors in integrated taxes at the time of filing GSTR 3B

3. Reasons for Mismatches in GSTR1 and GSTR 3B

Difference between GSTR1 and GSTR 3B, or mismatch on the following basis:

  • Furnishing supplies in GSTR 3B under the wrong head but declaring the same details in GSTR 1 correctly

    For Instance: Furnishing Zero-Rated Supplies under the Table 6A of GSTR 1, but furnishing the details wrongly under Table 3.1(a) in GSTR 3B.

  • Issuing invoices, debit and credit note for a particular month on a later date
  • Supplies made to an unregistered person furnished in GSTR 1 but not in GSTR 3B
  • Tax paid under the wrong head

    For instance, CGST and SGST in place of IGST or vice- versa

  • Tax liability change between GSTR 1 and GSTR 3B filling time
  • Reporting invoices in GSTR 1 and GSTR 3B at different time

    On the above-mentioned mismatches, there can be chances that you may get notices to form GST authorities. Moreover, this can also lead to a penalty plus interest. Hence, it is necessary for you to reconcile GSTR 1 and GSTR 3B.

4. Actions on GSTR1 and GSTR 3B Reconciliation

Considering the above-stated difference between GSTR 1 and 3B resulting in a lesser amount of tax paid. Then in such a case, the GST authorities may give you a show cause notice. In addition to this, you may have to pay the deficit tax amount along with interest.

5. The Bottom Line

Every taxpayer must carry out a reconciliation between GSTR1 and GSTR 3B so as to know if there are any discrepancies. The difference between GSTR 1 and 3B is that the former is focused on the taxpayer's outward supplies, while the latter gives an overview of all inward and outward supplies, tax liabilities, and claimed input tax credits.
