Mismatch in Input Tax Credit arising due to any difference in values between inwards supply details (furnished by businesses in their GSTR-3B) and outwards supply details uploaded by respective suppliers (available on GST portal as GSTR-2A) may lead to loss in the claimed Input Tax Credit (ITC).

Let’s look at how GSTR-3B and GSTR-2A mismatch can happen

Typically, you would have declared the consolidated value of your inward supplies in your monthly GSTR-3B returns. Your suppliers would have uploaded their sales invoices in GSTR-1, based on which your inward supplies get auto populated in GSTR-2A.

Now in case there are any discrepancies in the values of inward supplies available in GSTR-2A and inward supplies declared by you for the month in your GSTR-3B, it may lead to loss of Input Tax Credit.

Now let us understand the probable reasons for such mismatches.

Possible reasons for mismatches

1. Your supplier has not uploaded the invoices for which you have already claimed Input Tax Credit.
2. Values in the supplier’s invoices are not matching with values available in your books.
3. You might have missed out recording any Purchases or Debit Notes (Purchase Returns) which resulted in reduced Input Tax Credit.

How to identify GSTR-3B and GSTR-2A mismatch

1. Firstly, you must compare the purchases available in your books with GSTR-2A (available on GST Portal) of the respective returns period.
2. You can manually match each purchase invoice and identify the differences or identify invoices that are not available on the GST portal or in your books.
3. If you identify invoices whose values are either not matching or invoices are not available, connect with the respective supplier and ask him to either upload the related invoice in his latest return which is yet to be filed, or amend the invoice details at the time of filing his returns.
4. Alternately, you can check the physical copies of respective purchase invoices and correct your purchase data, and accordingly make corrections in your latest GST returns which are yet to be filed by reversing the Input Tax Credit.
