1. VARIOUS RECONCILIATIONS - EXPLANATIONS

A. Supplier-side Reconciliations

1. GSTR-2A vs Books (Purchase Register)

• Purpose: Identify missing credits, excess credits, ineligible credits.
• Key mismatches: Vendor not filed GSTR-1, wrong GSTIN, wrong tax rate, debit/credit notes not updated.

2. GSTR-2B vs Books

• Static statement basis for ITC availment.
• Key checks: ITC eligibility, blocked credits, ITC deferred due to time of supply issues.

3. Purchase Register vs GSTR-3B ITC Claimed

• Validates ITC actually claimed vs eligible ITC.
• Helpful in detection of wrong ITC, RCM missed entries.

B. Outward Supply Reconciliations

1. GSTR-1 vs Books (Sales Register)

• Ensures outward supplies reported accurately.
• Typical mismatches: Unreported invoices, amendments not passed, credit notes timing issues.

2. GSTR-1 vs GSTR-3B (Tax Liability)

• Identifies under-reporting/over-reporting of liability.
• Checks correctness of tax rate, place of supply, reverse charge liability reporting.

3. E-Invoices vs GSTR-1

• Ensures e-invoice IRN details match GSTR-1 auto-population.
• Identifies e-invoice errors or cancelled e-invoices not updated in returns.

4. E-Way Bills vs GSTR-1

• Ensures movement of goods is properly reported.
• Detects cases where goods moved but not reported in GSTR-1.

C. Other Critical Audit Reconciliations

• Books vs Annual Return (GSTR-9)
• Financial Statements vs GST Returns
• RCM Register vs GSTR-3B
• Turnover Reconciliation for Income Tax vs GST
