What Is GSTR-2B vs Books Reconciliation?
A quick, plain-language explanation before the details.
GSTR-2B vs books reconciliation matches the ITC in your monthly GSTR-2B against your purchase register, so you claim only eligible credit in GSTR-3B and catch any missing or mismatched invoices.
Under Section 16(2)(aa) of the CGST Act, 2017 and Rule 36(4), Input Tax Credit can be claimed only for invoices that appear in GSTR-2B. GSTR-2B is a static, auto-drafted ITC statement generated each month from suppliers’ GSTR-1, IFF, GSTR-5 and GSTR-6 filings.
Administered by the Goods and Services Tax Network (GSTN) under the Central Board of Indirect Taxes and Customs (CBIC), via the portal gst.gov.in. Rule 88D auto-intimates excess ITC in GSTR-3B over GSTR-2B through Form DRC-01C.
Reconciliation is an ongoing monthly cycle — done after GSTR-2B is generated (around the 14th) and before GSTR-3B is filed (by the 20th, or 22nd/24th for QRMP filers).

Talk to an Expert →Why Is GSTR-2B vs Books Reconciliation Important?
ITC is allowed only when an invoice appears in GSTR-2B. Reconciling protects the credit you claim and surfaces credit you might miss. Here is why it matters.
-
01
ITC Only If in 2B
Section 16(2)(aa) and Rule 36(4) allow ITC only when the invoice appears in GSTR-2B. Reconciliation protects every rupee of credit you claim.
-
02
Avoid ITC Reversal
Mismatched or supplier-not-filed credit must be reversed with 18% interest. Catch it before GSTR-3B, not after a notice arrives.
-
03
No DRC-01C Notices
Excess ITC in 3B over 2B (Rule 88D) triggers a DRC-01C intimation. Reconciling keeps GSTR-3B and GSTR-2B aligned.
-
04
Claim Full Eligible ITC
Reconciliation also surfaces credit you missed — invoices in 2B not yet booked — so no eligible ITC is left behind.
-
05
2B, Not 2A
GSTR-2B is static and the legal basis for ITC; 2A is dynamic. We reconcile against the correct statement every period.
-
06
Supplier Discipline
Flags non-filing and defaulting suppliers early, so you can follow up, hold payments or withhold the tax portion.

What You’ll Receive
What Is Needed for GSTR-2B vs Books Reconciliation?
Reconciliation matches two sets of records — what suppliers reported (GSTR-2B) against what you booked (purchase register). Share these securely online each cycle.
From the GST Portal
Downloaded each period- GSTR-2B for the tax period (static ITC statement)
- GSTR-2A (for cross-reference, if needed)
- Filed GSTR-3B of the period (for 3B vs 2B check)
- IMS status (accepted / rejected / pending invoices)
From Your Books
Your purchase records- Purchase register / ITC register for the period
- Vendor tax invoices with GSTIN, value & tax
- Debit / credit notes and RCM invoices
- Import (BOE) and reverse-charge records
Supplier & Reference
For follow-up & carry-forward- Vendor master with GSTINs and contacts
- List of suppliers who file late or default
- Prior-period reconciliation for carry-forward ITC
- Any DRC-01C / ASMT-10 notice received
Always reconcile against 2B
GSTR-2B is static and the legal basis for ITC under Rule 36(4). GSTR-2A is dynamic and keeps changing — never use it as the basis for your ITC claim.
IMS actions matter
Under the Invoice Management System, only accepted supplier records flow into GSTR-2B and your eligible ITC. Review accept / reject / pending before 2B is finalised.
Do it before GSTR-3B
Reconcile after GSTR-2B is generated (around the 14th) and before filing GSTR-3B — reconciling after filing means fixing errors under notice.
Mind the ITC cut-off
Prior-FY ITC can be claimed only up to 30 November of the next year (or the annual return, whichever is earlier). Reconcile in time to recover missed credit.

When Does Reconciliation Happen Each Month?
| Stage | Expected Time |
|---|---|
| GSTR-2B generated on the portal | Around the 14th |
| Match, flag & finalise eligible ITC | 14th–19th |
| Claim reconciled ITC in GSTR-3B | By the 20th (22nd/24th for QRMP) |
GSTR-2B is auto-drafted after suppliers file GSTR-1 (by the 11th). Reconciliation sits in the window between 2B generation and the GSTR-3B due date. QRMP filers still receive a monthly 2B, so a monthly reconciliation cycle is recommended even for quarterly return filers.

- Claiming ITC not reflected in GSTR-2B breaches Rule 36(4) and must be reversed with 18% interest under Section 50
- Excess ITC in GSTR-3B over GSTR-2B triggers a DRC-01C intimation under Rule 88D
- Supplier non-filing keeps invoices out of your 2B, so eligible credit cannot be claimed until it appears
- Eligible ITC sitting in 2B but never booked is lost after the 30 November cut-off
- Reconciling against dynamic 2A instead of static 2B invites reversal and demand
Regulatory Updates 2025–26
- 2025: The Invoice Management System (IMS) lets recipients accept, reject or keep invoices pending to finalise GSTR-2B and eligible input tax credit.
- 2025: DRC-01B (GSTR-1 vs 3B liability) and DRC-01C (ITC vs GSTR-2B) auto-intimations must be answered before further filing.
