Full GST Reconciliation: Step-by-Step Guide

GST reconciliation is one of the most important activities for ensuring accurate tax compliance, maximizing eligible Input Tax Credit (ITC), and avoiding notices, interest, and penalties.

At Goyal K & Co., Chartered Accountants in Gurgaon, we follow a structured GST reconciliation process to help businesses maintain clean and compliant records.

1. Purchase Input Tax Credit reconciliation

• Download GSTR-2A and GSTR-2B from the GST portal
• Export the purchase register from Tally, SAP, Zoho Books, or other accounting software
• Match GSTIN, invoice number, invoice date, taxable value, and GST amount
• Identify missing invoices, value mismatches, incorrect GSTINs, duplicate entries and ineligible ITC
• Classify ITC as eligible, ineligible or pending/unmatched

2. Sales output tax reconciliation

• Download filed GSTR-1 returns
• Export the sales register from accounting records
• Match invoice numbers, customer GSTINs, taxable values, and tax amounts
• Identify missing, duplicated, or incorrectly reported invoices
• Rectify discrepancies through amendments in subsequent GSTR-1 filings, where permitted

3. Reconciliation of GSTR-1 with GSTR-3B

• Compare taxable turnover reported in GSTR-1 with tax liability discharged in GSTR-3B
• Verify CGST, SGST, IGST, and Cess figures
• Identify under-reporting or over-reporting of tax liability
• Take corrective action through additional payment or adjustment as applicable

4. Reconciliation of GSTR-2B with GSTR-3B

• Compare ITC available in GSTR-2B with ITC claimed in GSTR-3B
• Identify excess or short claims
• Reverse ineligible ITC along with applicable interest, if required
• Claim eligible ITC in subsequent valid tax periods

5. Books of accounts vs GST returns

Reconcile turnover, purchases, GST liability, and ITC as per books with:

• GSTR-1
• GSTR-3B
