Under Rule 36(4) of the CGST Rules, 2017, matching the Purchase Register with GSTR-2B is a mandatory monthly statutory requirement. Failure to reconcile results in automated DRC-01C notices for excess ITC availed, attracting 18% per annum interest under Section 50(3) and potential penalty under Section 122. Unclaimed ITC lapses permanently on 30th November following the end of the financial year under Section 16(4).
Under Section 16(2)(aa) and Rule 36(4), ITC booked in accounting software (Tally, Busy, SAP) can only be claimed if it appears in GSTR-2B. Invoices recorded in books but missing in 2B must be withheld from Table 4(A)(5) of GSTR-3B. Invoices in 2B but omitted from books represent unbooked input credits requiring purchase voucher creation before the November 30 annual deadline.
Statutory Slabs & Rate Matrix
| Statutory Category | Audit Classification | Mandatory Statutory Action (CGST Act) | Risk Assessment & Rule 88D Standing |
|---|---|---|---|
| Fully Matched (Books == Portal) | Eligible Input Tax Credit | Claim 100% in Table 4(A)(5) of GSTR-3B for the tax period | Safe. Zero scrutiny risk or notice exposure |
| Value / Tax Mismatch (> ₹1) | Taxable / Tax Discrepancy | Restrict claim to lower of Books or 2B; notify vendor to file amendment (B2BA) | Excess claim triggers DRC-01C automated notice with 18% interest |
| In Books Only (Missing in 2B) | Supplier Non-Filing / Default | Withhold ITC in GSTR-3B. Follow up with vendor before statutory deadline (30 Nov) | Claiming without 2B reflection violates Section 16(2)(aa) |
| In Portal Only (Missing in Books) | Unbooked Purchase / Wrong GSTIN | Inspect missing vendor bill or ask supplier to cancel/amend wrong GSTIN pass-through | Opportunity loss if valid invoice, or credit leak if unbooked expense |
