# How to Reconcile GSTR-2B with Purchase Register (Step-by-Step Guide)
Reconciling your **Purchase Register** against **GSTR-2B** is one of the most critical monthly compliance steps for any business operating under Indian GST law. Failing to reconcile invoices can lead to unclaimed Input Tax Credit (ITC) worth thousands of rupees or tax notices from the department.
## Why GSTR-2B Matching is Essential in FY 2025-26
Under Section 16(2)(aa) of the CGST Act, a registered taxpayer cannot claim Input Tax Credit unless the supplier has uploaded the invoice in their GSTR-1 and it is reflected in the recipient's GSTR-2B statement.
- **Direct Financial Impact:** Unreconciled invoices mean you pay tax out of pocket.
- **Audit Protection:** Mismatches trigger DRC-01B notices automatically.
- **Supplier Accountability:** Identifying defaulting vendors allows you to hold payment until they file.
## 4-Step Manual vs Automated Matching Process
### Step 1: Export Purchase Data from Accounting Software
Export your monthly Purchase Register from Tally Prime, Busy, Marg, or Zoho Books in Excel (.xlsx) format. Ensure mandatory fields like Supplier GSTIN, Invoice Number, Invoice Date, Taxable Value, CGST, SGST, and IGST are included.
### Step 2: Download Official GSTR-2B from GST Portal
Log into the GST Portal (services.gst.gov.in), navigate to Return Dashboard, select the tax period, and download GSTR-2B in Excel or JSON format.
### Step 3: Match Invoices & Identify Discrepancies
Compare each invoice line-by-line across four categories:
1. **Matched Invoices:** Perfect match on GSTIN, Invoice No., Date, and Tax amount.
2. **Tax Mismatches:** Invoice numbers match, but tax rates or values differ.
3. **Missing in GSTR-2B:** Recorded in purchase register but supplier hasn't filed GSTR-1.
4. **Missing in Purchase Register:** Present in GSTR-2B but omitted in your books.
### Step 4: Act on Mismatches & Claim ITC
- Claim ITC only on matched invoices.
- Notify defaulting suppliers with a list of unfiled invoices.
- Use automated tools like **GSTMatch** to run AI-powered fuzzy matching in 2 minutes.
