What is GSTR-2A?

GSTR-2A is a read-only auto-generated return that shows the details of all inward supplies (purchases) made by a registered taxpayer. It is generated based on the GSTR-1 filed by your suppliers. Whenever your vendors upload invoices where your GSTIN is mentioned, those details reflect in your GSTR-2A.

When is GSTR-2A Generated and Updated?

GSTR-2A is a dynamic auto-drafted return generated for the recipient of goods and services. It is populated based on the supplier’s GSTR-1, GSTR-5, GSTR-6, GSTR-7, and GSTR-8 filings.

  • Initial Generation: As soon as a supplier files GSTR-1, the invoice details are reflected in the recipient’s GSTR-2A.
  • Real-Time Updates: GSTR-2A gets updated in real-time whenever a supplier uploads or modifies their invoices.
  • Multiple Updates: It may change several times in a month, especially if the supplier files late or amends invoices.

Because of its dynamic nature, it’s important to check GSTR-2A frequently to:

  • Verify the accuracy of input tax credit (ITC)
  • Detect any missing invoices
  • Avoid errors while filing GSTR-3B or GSTR-9

How to File GSTR-2A?

GSTR-2A is a document that does not require to be filed since it is auto-populated based on other forms. However, businesses can accept, reject, modify, or defer its acceptance if any organisation finds any discrepancy in the invoice details that its seller submitted in  GSTR-1 .

What are the Reasons for Non-Reconciliation?

Non-reconciliation between GSTR-2A and  GSTR-3B  happens for various reasons. Common issues include discrepancies in invoice details uploaded by suppliers, such as wrong GSTIN, incorrect invoice numbers, or mismatches in invoice values.

Another reason could be the supplier’s delayed  filing of gst returns , causing a mismatch in the periods reflected in GSTR-2A. Additionally, taxpayers may claim ITC for invoices not yet uploaded by their suppliers, leading to discrepancies. Regular reconciliation helps avoid these issues.

GSTR-2A vs GSTR-2B – What’s the Difference?

While both GSTR-2A and GSTR-2B reflect inward supplies for ITC purposes, there are key differences:

Criteria GSTR-2A GSTR-2B
Nature Dynamic and continuously updated Static and generated monthly
Basis of Generation Based on real-time supplier uploads Generated on a cut-off date (12th of next month)
Purpose For reconciliation For ITC claim in GSTR-3B
Changes Possible Yes, updated frequently No, remains fixed for that period
Use for ITC Reference only Preferred for actual ITC claim

GSTR-2B is more reliable for final ITC claim, while GSTR-2A is better for ongoing reconciliation and monitoring supplier compliance.

What are the Reasons for GSTR-2A and GSTR-3B Mismatches?

Discrepancies between GSTR-2A and GSTR-3B are common and can lead to ITC disallowance or scrutiny. Some typical reasons include:

  • Supplier hasn’t filed GSTR-1: If the supplier delays or skips filing GSTR-1, their invoices won’t reflect in your GSTR-2A.
  • Wrong GSTIN or invoice date: Incorrect entry of your GSTIN or invoice date by the supplier prevents the invoice from appearing in your GSTR-2A.
  • Invoice not uploaded: Suppliers may forget to upload invoices, especially for B2B transactions.
  • Difference in tax rates or invoice amounts: Mistakes in tax rate, taxable value, or total invoice amount lead to ITC mismatch.
  • Claimed in advance: If you claim ITC in GSTR-3B before it appears in GSTR-2A (e.g., supplier files later), it creates a temporary mismatch.

To resolve these mismatches:

  • Regularly reconcile GSTR-2A and GSTR-3B.
  • Follow up with non-compliant suppliers.
  • Use automation tools for quicker detection and resolution.

Why is GSTR-2A Reconciliation Important?

GSTR-2A is important because it helps businesses ensure that the Input Tax Credit (ITC) they claim matches the invoices uploaded by their suppliers. If there’s a mismatch between your purchase records and what suppliers report, your ITC claim may be reduced or disallowed.

Key Reasons Why Reconciliation Matters:

  • Ensures correct ITC claim – Only matched invoices are eligible for input credit.
  • Avoids GST notices – Mismatches can trigger notices or audits from the tax department.
  • Identifies missing invoices – Helps follow up with suppliers who haven’t filed GSTR-1.
  • Improves compliance – Accurate reporting reduces errors in GSTR-3B and annual returns.
  • Prevents tax loss – Reduces the risk of losing eligible credits due to supplier delays.

Regular reconciliation with GSTR-2A helps keep your GST records accurate, saves money, and avoids penalties.

Deadline for Submitting Documents to the IRP

When registering e-invoices with the Invoice Registration Portal (IRP), submitting the invoices within the prescribed time is essential. No strict deadline is mentioned for document submission, but it’s recommended that invoices be uploaded promptly after they are generated.

The IRP validates the authenticity of  e-invoices  and generates an  Invoice Reference Number  (IRN). Once validated, the IRN and QR code must be shared with the buyer to maintain compliance with GST regulations.

What are the Modes for Registering E-Invoices in IRP?

Several modes are available for registering e-invoices with the  Invoice Registration Portal  (IRP). You can register through the Web-based portal, which allows manual entry of invoice details. Another option is the API integration with your ERP system for bulk and automated uploads.

The Bulk Upload Tool is useful for larger organisations that must submit multiple invoices simultaneously. Additionally, there is the option to register via GSP (GST Suvidha Providers), which acts as an intermediary.

What Happens if the Seller Delays Filing GSTR-1 or Fails to Upload Invoices?

Input tax credits for those invoices that weren’t uploaded on time or weren’t uploaded at all won’t show up in GSTR-2A for the applicable tax period. It may be necessary for the buyer to inform his non-compliant vendors or suppliers of this for them to update any missing invoices promptly. As of August 2020, every buyer must use  GSTR-2B  rather than GSTR-2A to determine the amount of input tax credit he is eligible for during a given tax period.

According to CGST Rule 36(4), the buyer might have claimed an input tax credit on a provisional basis in his GSTR-3B up until December 31, 2021, to the extent of 5% of the eligible tax credit appearing in GSTR-2B toward the invoices not discovered in GSTR-3B.

However, due to the modification made to CGST Rule 36(4), it will not be possible to claim such a 5 per cent provisional or additional  Input Tax Credit  (ITC) starting from 1 January 2022. A buyer may claim only Input Tax Credit showing in GSTR-2B under the CGST Act’s Section 16(2)(aa).

What are the Details Featured in GSTR-2A?

Under GSTR-2A, there are seven sections per the government’s mandate.

  1. GSTIN
  2. Name of the Taxpayer

Part A

  1. Inward supplies received from a registered person other than the supplies attracting reverse charge.
    Most of the purchases made from sellers will have their information automatically filled in here from their GSTR-1 filings. Details, including the type, rate, and amount of GST, as well as the eligibility and amount of Input Tax Credit, would be included. It won’t, however, include any purchases made through  reverse charge .
  2. Inward supplies received from a registered person on which tax is to be paid on reverse charge
    All purchases and supplies you receive (from both taxable and non-taxable persons) for which you must pay GST under reverse charge will be included in this.
  3. Debit / Credit notes (including amendments thereof) received during the current tax period.
    This will capture the details of debit and  credit notes  issued by the sellers during the month. It will also reflect any modifications made by comparing the updated documents with the originals.

Part B

  1. ISD credit (including amendments thereof) received
    When your head office files the GSTR-6 return for the month, the information in this area will automatically be filled in if you are a branch.

Part C

  1. TDS and TCS Credit (including amendments thereof) received
    TDS Credit Received – You will only be subject to this section if you enter into specific agreements with certain parties (usually government bodies). A particular portion of the transaction value will be withheld by the receiver (the government) as tax deducted at the source. The GSTR-7 that the deductor filed will automatically populate this form with all the data.

TCS Credit Received – This heading only applies to online sellers with an active account with an e-commerce operator. When paying such merchants, e-commerce firms must collect tax at the source. Once more, this data will be automatically filled in from the e-commerce operators’ GSTR-8.

Conclusion

GSTR-2A is a GST Return showing purchase related information for the period for which it is being filed. It is an auto-populated Return created for every business that is registered under GST. The data in GSTR-2A is populated based on the data provided by suppliers while filing GSTR-1, or when suppliers issue credit or debit notes. The data populated in GSTR-2A is used mainly for informational purposes only. Thus, it cannot be edited. Filing GST Returns can be a complicated process. Make it simple and easy with robust  GST Accounting Software  like BUSY.
