Comparison of GSTR-3B vs GSTR-2A : Importance & Report

Updated on :  

08 min read.

GSTR-3B vs GSTR-2A is an important exercise that businesses must not miss out on. It helps businesses claim the full Input tax credit (ITC) and also reverse any excess ITC claimed. In turn, the reconciliation before filing GSTR-3B will help avoid any potential demand notices from the tax authorities. With GSTR-2B introduced in July-August 2020, matching ITC to be claimed in GSTR-3B with GSTR-2A has now moved to a yearly affair, yet important for TDS and TCS credit.

Form GSTR – 3B is a monthly summary return filed by the taxpayer by the 20th of the next month or 22nd/24th of month following the quarter. Taxpayers are allowed to take the input tax credit (ITC) based on the details declared by the taxpayer in Table 4 of Form GSTR – 3B:

Form GSTR – 2A is an auto-populated form generated in the recipient’s login, covering all the outward supplies (Form GSTR – 1) declared by his suppliers.

When the supplier files GSTR – 1 in any particular month disclosing his sales, the corresponding details are captured in GSTR-2B and GSTR – 2A of the recipient. While the filing of Form GSTR – 2 has been kept in abeyance, it’s still important under the GST framework for the taxpayers to reconcile the ITC claimed in Form GSTR – 3B and Form GSTR – 2A. GSTR – 3B is a summary return. Hence, the amount of ITC available as disclosed in Table 4(a) must match with tax details disclosed in Form GSTR-2B regularly, along with GSTR – 2A.

Importance for GSTR-3B vs GSTR-2A

It is important to reconcile Form GSTR – 3B and Form GSTR – 2A on account of the following reasons:

  • GST authorities have issued notices to a large number of taxpayers asking them to reconcile the ITC claimed in a self-declared summary return Form GSTR – 3B with the auto-generated Form GSTR-2B and Form GSTR – 2A. Such notices are issued in Form GST ASMT – 10. The taxpayer would be required to reply to such notices or pay the differential amount.
  • Tax evaders claiming ITC on the basis of fake invoices have also been penalised in the past.
  • Reconciliation ensures that credit is being claimed for the tax which has been actually paid to the supplier.
  • Ensures that no invoices have been missed/recorded more than once, etc.
  • In case the supplier has not recorded the outward supplies in Form GSTR – 1, communication can be sent out to the supplier to ensure that the discrepancies are corrected.
  • Errors committed while reporting details in GSTR-1 by suppliers or GSTR-3B by recipients can be rectified.

Use the ClearTax GST software to identify the differences between the GSTR-3B vs GSTR-2A/2B vs books . 

Reconciliation at the time of filing of Annual return: Even at the time of filing an Annual return in Form GSTR – 9, reconciliation of ITC as per GSTR – 3B and GSTR – 2A is required to be done in Table 6 and Table 8 across months.

Reasons for non-reconciliation of GSTR-2A vs 3B

The details disclosed in Form GSTR – 2A and Form GSTR – 3B may not reconcile on account of the following reasons:

  • The credit of IGST claimed on the import of goods
  • IGST Credit on the import of services
  • The credit of GST paid on reverse charge mechanism, etc.
  • Transitional credit claimed in TRAN – I and TRAN – II.
  • ITC for goods and services received in FY 2020-21 but availed in FY 2021-22.

In the cases mentioned above, the figures will not reconcile as no corresponding Form GSTR – 1 is filed by the supplier or the ITC is being claimed at a later date.

After Identifying mismatches by GSTR-2A vs GSTR-3B

After considering the situations mentioned above, if any discrepancies are found in Form GSTR – 2A and GSTR -3B leading to any excess ITC claimed by the recipient, the same must be paid by the taxpayer along with interest. It is, therefore, necessary that this reconcile exercise is done on a regular basis to ensure that only bonafide input tax credit is claimed.
