GST Reconciliation

GST Reconciliation: Importance, Process & Common Issues

📘 What is Reconciliation?

In general terms, reconciliation refers to comparing two sets of records to identify and correct discrepancies or omissions. In the context of taxation, reconciliation plays a vital role in ensuring the accuracy of tax reporting and compliance.

Discrepancies in reconciliation can lead to underpayment, overpayment, or non-payment of taxes. Such inconsistencies, if left unaddressed, may result in scrutiny notices, penalties, or even suspension of GST registration.

🔍 Why GST Reconciliation is Important

Regular reconciliation under GST is essential to:

• Ensure accurate claim of Input Tax Credit (ITC).

• Avoid penalties or legal consequences from incorrect tax reporting.

• Detect and rectify errors or mismatches before filing returns.

• Strengthen vendor compliance through follow-ups and rectifications.

🔄 Common Types of GST Reconciliation

Below are some key reconciliation types that businesses must perform:

1. GSTR-3B vs GSTR-2A / GSTR-2B (Input Tax Credit)

Compare ITC claimed in GSTR-3B with ITC auto-reflected in GSTR-2A/2B to identify any excess or ineligible claims.

2. GSTR-3B vs GSTR-1 (Outward Supplies)

Match sales reported in GSTR-3B with those declared in GSTR-1 to check for omissions or reporting mismatches.

3. Books of Accounts vs GSTR-1 (Sales)

Ensure that outward supplies in the books match the auto-populated GSTR-1 data generated from e-invoicing.

4. GSTR-2B vs Books of Accounts (ITC)

Identify discrepancies between ITC values in books and GSTR-2B, especially relevant after 1st Jan 2022 with the removal of provisional ITC.

5. Auto-Populated GSTR-3B vs Books of Accounts (Tax Payable)

Reconcile actual tax liabilities from books with values populated in GSTR-3B.

🛠️ Common Causes of GST Mismatches

1. Credit not availed though vendor declared liability

   • Must be claimed on or before the earlier of:

     • September return due date of the subsequent financial year, or

     • Date of filing the Annual Return.

2. Credit availed but vendor hasn’t declared liability

   • Requires immediate vendor follow-up; otherwise, such credit may be disallowed.

3. Mismatch between vendor-declared liability and credit claimed

   • Identify reasons (e.g., wrong invoice amounts) and resolve via debit/credit notes.

   • Deadline: Before filing return under Section 39 for September or annual return.

4. Data entry or reporting errors

   • Errors in GSTIN, invoice number/date, or taxable values should be corrected by amendments in the next month’s return.

📅 Timelines for Reconciliation

To preserve eligibility for ITC, reconciliation must be completed before:
