A Guide on How to File GSTR 2A Using Offline Utility

Key Takeaways
- GSTR-2A is a read-only, auto-generated statement that reflects inward supplies based on your suppliers' filings.
- While GSTR-2A cannot be filed, it plays a vital role in verifying purchase records and reconciling input tax credit.
- Use GSTR-2A for real-time tracking, but rely on GSTR-2B for final ITC claims in GSTR-3B filings.
- The GST Returns Offline Tool allows you to manage and validate large volumes of invoice data offline.
- Generating and uploading JSON files through the offline utility ensures accurate and error-free GST compliance.
Navigating the complexities of GST compliance can feel overwhelming, especially when dealing with purchase records and input tax credits (ITC). A key part of GST involves handling different forms, and GSTR-2A is one of them. This auto-generated statement captures all inward supplies reported by your suppliers and helps you cross-check your input tax credit accurately.
While you do not file GSTR-2A directly, reviewing it regularly is crucial to maintain error-free returns. For businesses managing large invoice volumes or limited internet access, this GST offline tool offers a practical solution.
In this guide, we will explain how GSTR-2A works and walk you through the steps to prepare your data efficiently for accurate return filing.
What Is GSTR 2A?

GSTR-2A is a purchase-related statement that the GST portal auto-generates for every business registered under the GST system. It records all inward supplies (goods and services) purchased during a specific month.
Once a supplier (the registered taxpayer) files their Form GSTR-1 return, your purchase details reflect in your GSTR-2A invoices. This document mirrors the data your vendors submit in their GST returns.
As a GST-registered buyer, you can use GSTR-2A to verify and match your input tax credit while filing GSTR-3B and GSTR-9.
Since August 2020, GSTR-2B, a fixed monthly statement, serves as the standard for GSTR-3B preparation.
Should I Refer to GSTR-2A or GSTR-2B?
Choosing between GSTR-2A and GSTR-2B for claiming Input Tax Credit depends on how precise and consistent you want your data during filing.
GSTR-2A is dynamic and updates as suppliers upload invoices, which means it changes throughout the month. While it helps track purchases in real time, relying only on it can cause mismatches, as tax invoices might be added or modified after you file.
In contrast, GSTR-2B is a fixed monthly statement that offers a stable, unchanging view of eligible ITC. It helps reconcile purchase records accurately and reduces errors during filing.
Therefore, you should use GSTR-2A data for tracking, but depend on GSTR-2B for final ITC claims to ensure accurate and hassle-free compliance.
How to File GSTR 2A Using Offline Utility?
As discussed earlier GSTR 2A is a read-only file, that cannot be edited or filed, here is a step-by-step guide on how to view GSTR-2A data using the offline utility. Let us start by downloading the GST Returns Offline Tool to downloading the form and opening it using the tool:

How to Install the GST Returns Offline Tool?
Follow these simple steps to complete the process:
Step 1: Find the ZIP file named gst_offline_tool.zip in your system. Right-click on it and extract the contents. You will see the following files:
● GST Offline Tool.exe: The main setup file for installation.

Save the Excel and CSV templates safely. You will need them to prepare your return filing process.
Step 2: Enter data only in the applicable sections of your return. If a section does not apply, leave it blank. The tool will use only the filled-in parts.

Step 4: Once installed, keep both checkboxes ticked and click 'Finish'. This will open the tool.
A shortcut will appear on your desktop. You can double-click this icon anytime to use the tool.
Note: If you uninstall and reinstall this tool, use the same folder. If you change location, restart your computer before using the tool again. If you do not, the tool may not open.

Uploading Invoice Data in FORM GSTR-1 or IFF Using the Returns Offline Tool

To upload outward supply invoices for a specific financial year and return period, follow the steps below using the Returns Offline Tool. Let us assume the return is for January in the financial year 2023–24.

Step 2: Start a New Upload
- Click the 'New' button. The File Returns page will open.

Step 3: Enter Invoice Data
You can upload your invoice details using any of the four options below:

● Copy and Paste from Excel: Copy invoice data from your Excel sheet and paste it directly into the tool.
● Import CSV File: Upload invoice data using the prescribed CSV format. This method is quick if your data is already formatted correctly.
Generating the JSON File for GST Portal Upload
Once you have reviewed the summary of your invoice data, follow these steps below to generate the JSON file required for upload to the GST Portal.
Step 1: Generate the File
- Click on the 'Generate File' button within the offline tool.
- A GSTR-2A JSON file will be created containing all the invoice details you entered.
Note: Your file size must not exceed 5 MB. If your file is too large:
● Delete a few invoices to reduce the size.
● Generate the JSON file again.
● Save the removed invoices separately, add them later and create another JSON file.
You can repeat this process to create multiple JSON files for the same return period. Make sure to name each file clearly so you can identify them easily later.
Step 2: Save the JSON File
- When prompted, click the 'Save' button.
- Choose a location on your computer to store this file.
- Select a name for this file that helps you recognise its contents.
Note: If you create more than one JSON file for the same month, the tool may suggest the same default name. Rename each file manually to avoid confusion.
You have almost completed your process of preparing your GST return using the Offline Utility. To wrap up, follow these final steps:
- Once saved, your JSON file is ready to be uploaded on the GST Portal. The portal will validate your data and reflect the uploaded invoices.
- If you find any error after upload, the portal will allow you to download an error file to identify and correct the issues. Once corrected, generate a fresh JSON file and upload it again.
- You can download your submitted GSTR-1/IFF Return File and open it in your Offline Tool if required.
- To verify your purchase data, download your GSTR-2A from the portal. Open it in the Offline Tool to cross-check supplier-submitted invoices and reconcile them with your records.
These final checks reduce your chance of mismatches and help maintain error-free compliance activities.
