Recalculate GSTR-2B Automatically in TallyPrime: A Smart GST Solution

Published on: 22-07-2025

Introduction

In the evolving landscape of GST compliance, GSTR-2B plays a critical role in determining Input Tax Credit (ITC). Introduced as a static, auto-drafted statement by the GST portal, GSTR-2B helps taxpayers match their purchase records with supplier data. However, real-time business dynamics often demand recalculation and reconciliation of GSTR-2B on a dynamic basis. With the increasing push towards automation and accuracy, TallyPrime—a trusted accounting and ERP software—offers solutions to dynamically recalculate GSTR-2B and manage discrepancies effectively.

This article explores how to perform dynamic GSTR-2B recalculation in TallyPrime, benefits, key processes, and tips to ensure compliance.

Understanding GSTR-2B and Its Importance

GSTR-2B is a monthly auto-generated statement available to GST-registered buyers. It provides a summary of eligible and ineligible ITC, based on supplier GSTR-1/IFF, GSTR-5, and GSTR-6 filings. The key difference between GSTR-2A and GSTR-2B is:

• GSTR-2A is dynamic – it keeps updating.
• GSTR-2B is static – frozen on the 13th of every month.

Despite GSTR-2B being static, businesses often need to reconcile real-time purchase data, especially when:

• Supplier files GSTR-1 late.
• There are mismatches in invoice dates or GSTINs.
• ITC claimed does not match portal data.

What is Dynamic GSTR-2B Recalculation?

Dynamic recalculation means recomputing ITC eligibility in real-time as your inward supply data changes—irrespective of when suppliers update their returns.

TallyPrime facilitates this by:

• Importing GSTR-2B JSON from the GST portal.
• Mapping and matching supplier invoices.
• Highlighting mismatches and unclaimed ITC.
• Allowing user-based override and adjustment.

How to Perform Dynamic GSTR-2B Recalculation in TallyPrime

Let’s walk through the step-by-step process.

Step 1: Enable GST and GSTR-2B Features

1. Go to F11: Features > Statutory & Taxation.
2. Enable Goods and Services Tax (GST).
3. Provide your GSTIN and select the state.
4. Set Enable GSTR-2B Reconciliation to Yes.

Step 2: Download GSTR-2B JSON from GST Portal

1. Log into the GST portal.
2. Go to Returns Dashboard > GSTR-2B.
3. Select the month and download the JSON file.

Step 3: Import GSTR-2B into TallyPrime

1. Open TallyPrime and go to Gateway of Tally.

3. Select the appropriate month.
4. Use the Import JSON option and load the file.
5. TallyPrime will automatically parse the file and match it with your purchase vouchers.

Step 4: Analyze the Reconciliation Report

TallyPrime generates a comprehensive reconciliation report with the following categories:

• Matched Invoices – Fully reconciled.
• Mismatched Invoices – Discrepancies in invoice number, GSTIN, or date.
• Missing In Tally – Invoices present in GSTR-2B but not recorded in Tally.
• Missing in GSTR-2B – Recorded in Tally but not found in GSTR-2B.

You can drill down into each invoice and analyze differences.

Step 5: Perform Dynamic Recalculation

TallyPrime lets you perform dynamic actions:

• Adjust Purchase Vouchers to fix mismatches.
• Re-import Updated JSON anytime.
• Manually tag unmatched entries to available invoices.
• Override eligibility status (e.g., mark ITC ineligible).
• Get a real-time calculation of total ITC available.

The recalculation is dynamic because any change in your books or re-import immediately updates the reconciliation outcome.
