GST Input Tax Credit can be availed without any blocking of your credit if it is done in a right way. This article is mainly focused on ITC claim in GST and its dependence on ITC reconciliation process.

Claiming of GST Input Tax Credit on the purchases made can be difficult and availing only the eligible ITC can be a tricky business. However, if proper guidelines are followed and GST provisions are adhered to then claiming ITC can be an easy task.

Flawless reconciliations, manual error minimization and timely follow-ups with your suppliers can allow you to claim maximum eligible ITC for the month and your working capital will not be blocked.

In this comprehensive article we have discussed the importance of ITC reconciliation to claim maximum eligible Input Tax Credit. We have also discussed the elevated role of Form GSTR 2B in the process of claiming eligible Input Tax Credit.

ITC claim in GST & related Reconciliations

Reconciliation under GST involves matching outward supplies and purchase records between different GST returns like GSTR-1, GSTR-2A, GSTR-2B, GSTR-3B, GSTR-9, GSTR-9C & Books of Accounts.

These reconciliations ensure no inconsistencies in your GST returns as per the GST laws, and you pay the tax equal to your outward tax liability, no less and no more. Moreover, they ensure detailed scrutiny of all the GST returns for anomalies, which helps in a flawless GST return and further a seamless claim for Input Tax Credit under GST.

All these reconciliations hold equal importance in claiming eligible & 100% Input Tax Credit for the taxes paid on the purchases by the taxpayer.

Outputs of a successful reconciliation by a GSTR 2B Reconciliation software

On running a successful Reconciliation between two GST data sets, the following are the outputs received within the reconciliation report:



Matching records

These entries are valid, and there is no issue when two GST data sets are compared head-to-head.

Mismatching records

These entries indicate that there are mismatches in the values of some of the fields. For example, The tax rate, invoice date, or invoice number do not match between two sets of data like GSTR-2B and Purchase Record.

Missing records in Books

These entries are found in the GST returns but are missing from the taxpayer's purchase records.

Missing records in GSTR-2A/2B

These entries are found in the purchase records of the taxpayer, but they are absent in the monthly auto-generated GSTR-2A or GSTR-2B of the taxpayer. This mainly happens due to irregular GSTR 1 return filing by your suppliers, which negatively impacts your GST Input Credit claim for that month.

Hence businesses must run ITC reconciliation to identify only the eligible ITC.

It's the responsibility of the taxpayers to take immediate action on all the mismatched entries and rectify them as soon as possible. In addition, the taxpayers must develop a communication channel between the GST defaulting suppliers and their clerical team to notify these vendors about this irregularity immediately.

If the reconciliation activity is not run regularly, your business will lose the Input Credit and pay your outward GST liabilities in cash. This will take a toll on the business's working capital, creating a cash crunch.

It’s essential that the business has an effective GSTR 2B reconciliation software to carry out all these activities.

One of the biggest problems that result from manual reconciliation under GST is the lack of standardization for large enterprises.

Many of India's small & medium-sized businesses still prefer manual reconciliation over automated one. But once the number of invoices goes up, it becomes challenging to reconcile your Purchase Registers against your GSTR-2B. As a result, your business loses eligible Input Tax Credit under GST.

Following are some of the direct risks that your business faces in carrying manual GST reconciliation:

  • Risk of error introduction in your GSTR 9 annual return.
  • Invoice number mismatches in your Purchase register against the invoices you have received from your supplier and reflecting in the FORM GSTR-2B.
  • Mismatch in the invoice date as the date of recording the invoices at the seller's and the purchaser's side is different.
  • When the number of invoices increases, this takes up a lot of time for the clerical team to reconcile every invoice received from the supplier and check its validity.

Automating your GSTR-2B vs Purchase Records reconciliation using and automated GSTR 2B reconciliation software will save time and give you a comprehensive report showing the statement's mismatches and the eligible ITC.

ITC Claim in GST & Role of GSTR 2B Recon vs Purchase

ITC reconciliation always involves the data from the GSTR-2B.

Hence it is important to understand the role of GSTR-2B in the ITC reconciliation process.

Details of your purchases shall reflect in your GSTR-2B ONLY if your Supplier has filed his GSTR-1 correctly & on time corresponding to the purchase.

It is essential that the businesses identify their eligible ITC based on a reconciliation of their Purchase records and the monthly auto-generated GSTR-2B.

Reconciling Purchase Records vs GSTR-2B

  • The best way to find gaps in your GSTR-2B statement is to reconcile your auto-generated GSTR2B against your Purchase Records or Books of Accounts.
  • This is the best way to find out ITC for which transactions are missing in your GSTR-2B statement.
  • Manual reconciliation is possible for a smaller volume of transactions. But what if the transaction volume is bulky?
  • The bulky volume of transactions will surely be a problem, and the clerical team will get immersed in these reconciliations and lose a lot of business time and resources.

The supplier files his GSTR-1, and it is reflected under GSTR-2A and GSTR-2B of the recipient.

These are the periodic return filed by the taxpayer that covers all the details for that particular period, such as outward supply, inward supply, tax amount, interest or penalty, if any, etc.

Importance of GSTR-3B and GSTR-2A/2B Reconciliation

  • Removal of cascading effect is an essential aspect of GST.
  • A registered taxpayer will be eligible to the ITC claim for GST paid on inward supplies.
  • GSTR2A  contains the detail of inward supplies made.
  • GSTR-2A will show the details uploaded by the supplier, but under form GSTR 3B, the taxpayer will himself upload the details to claim ITC for the particular tax period.
  • Only ITC available in the GSTR-2B of the month shall be considered the eligible ITC.

A flawless reconciliation between your GSTR-2B statement and your GSTR-3B return ensures no differences in the Input Credit claimed by you and the actual Input Credit available to you in the GSTR-2B statement.

Thus, GSTR-3B vs 2B is an important reconciliation for 100% GST compliance.

What is Blocking your eligible ITC?

ITC reconciliation process
  • Taxpayer’s tend to ignore the GST provisions & GST laws to claim ITC in GST.
  • An inefficient ITC reconciliation process results in mismatches in the final ITC claim, and the issues stay hidden from the taxpayer.
  • Reconciliation is considered a 'consulting activity' and NOT a 'routine business activity.
  • Manual reconciliation is error-prone due to its inefficiency and time-consuming procedure.
  • Vendor communication is missing. An automated mechanism of on-time follow-ups with the defaulting vendors is not in place; hence, many instances go unnoticed.
  • Absence of an automated reconciliation system to identify such defaulting vendors, reach out to them and notify them about the discrepancies in the return filing.
  • ERP systems do not support payment holding features for the defaulting suppliers.
