GSTR-2B Reconciliation & ITC Services

Monthly GSTR-2B reconciliation and input tax credit (ITC) advisory for businesses that want to claim 100% of eligible credit and stay protected from departmental notices. Our team performs invoice-level matching, flags ineligible ITC under Section 17(5), and ensures every GSTR-3B reflects accurate, defensible input tax credit.

Reconcile My GSTR-2B

What is GSTR-2B?

GSTR-2B is a static, auto-drafted ITC statement generated by the GSTN portal for every registered recipient on the 14th of each month. It captures invoices and debit/credit notes uploaded by suppliers between the 12th of the previous month and the 11th of the current month, and classifies them as ITC available, ITC not available, or ineligible.

Under Section 16(2)(aa) of the CGST Act and Rule 36(4), input tax credit can be claimed only if the corresponding invoice appears in GSTR-2B. This makes GSTR-2B the single most important monthly document for ITC compliance. Errors or gaps in reconciliation directly translate into blocked ITC, working-capital strain, and Section 73/74 notices.

Why GSTR-2B Reconciliation is Critical

ITC can only be availed in GSTR-3B to the extent it appears in GSTR-2B for the relevant period.
Ineligible ITC under Section 17(5) — blocked credits on motor vehicles, food, club memberships, personal expenses, etc. — must be excluded.
ITC on invoices missing in GSTR-2B leads to working-capital lock-in and supplier disputes.
Excess ITC availed triggers reversal with interest at 18% under Section 50 and penalty exposure.
Robust monthly reconciliation provides a clean trail for GSTR-9 and GSTR-9C disclosures.

Invoice in GSTR-2B, missing in books — duplicate billing, fraudulent invoices, or unrecorded purchases.
Value mismatch — wrong invoice value, tax rate, or place-of-supply between books and supplier filing.
Period mismatch — invoice booked in current month but reported by supplier in a different month.
Wrong GSTIN — supplier filed invoice under a different GSTIN of yours (e.g. wrong state).

Frequently Asked Questions

When is GSTR-2B generated each month?

GSTR-2B is auto-drafted by the GSTN portal on the 14th of every month, covering invoices uploaded by suppliers between the 12th of the previous month and the 11th of the current month.

Can I claim ITC on an invoice that does not appear in GSTR-2B?

No. Under Section 16(2)(aa) of the CGST Act, ITC can be claimed only if the corresponding invoice appears in GSTR-2B for the relevant tax period. Until the supplier files or amends their GSTR-1 to reflect the invoice, ITC cannot be availed.

What is the difference between GSTR-2A and GSTR-2B for ITC purposes?

GSTR-2B is static and locked, making it the basis for monthly ITC determination. GSTR-2A is dynamic and updates whenever suppliers file or amend their returns; it is more useful for full-year reconciliation. See GSTR 2A Reconciliation.

What are blocked credits under Section 17(5)?

Section 17(5) of the CGST Act lists ITC that is not allowed even if it appears in GSTR-2B — including credit on motor vehicles (subject to exceptions), food and beverages, club memberships, life and health insurance, employee gifts, construction of immovable property, and personal-use expenses.

What if I have already availed ITC that is not appearing in GSTR-2B?

Excess ITC availed must be reversed with interest at 18% per annum under Section 50, either in the next GSTR-3B or through a voluntary DRC-03 payment. Continuing to retain such ITC exposes the business to demand notices under Sections 73 / 74.

How often should GSTR-2B reconciliation be performed?

GSTR-2B reconciliation should be performed every month before filing GSTR-3B. A consolidated annual reconciliation is also recommended before GSTR-9 filing to capture year-end adjustments.
