GSTR-2B and How to Match It

GSTR-2B is the statement on the GST portal that tells you which purchase invoices your suppliers have reported, and therefore how much input tax credit you can claim. Matching it with your own purchase register every month is the single best habit for a GST-registered shop.

What GSTR-2B is

GSTR-2B is an auto-drafted, static statement of input tax credit generated for each return period. It is built from what your suppliers file in GSTR-1, GSTR-1A or IFF, and from other sources such as import data. Unlike its live cousin GSTR-2A, it does not change after it is generated, so it is the reference for what you can claim in GSTR-3B for that period.

Section 16(2)(aa) of the CGST Act allows input credit only when the supplier has reported the invoice and it appears in the statement given to you, so an invoice missing from GSTR-2B is, for now, credit you cannot take.

When it is generated

Monthly filers: on the 14th of the month following the tax period
Quarterly (QRMP) filers: for the quarter, on the 14th of the month after the quarter
Through the Invoice Management System (IMS), you can accept, reject or keep pending each supplier record before GSTR-3B; records with no action are treated as accepted when GSTR-2B is generated
If you act on records in IMS after the 14th, you can recompute GSTR-2B before filing GSTR-3B

Worked example: matching one month

Sri Lakshmi Stores in Mysuru recorded 42 purchase bills in October 2026 with total input GST of ₹18,600. Its GSTR-2B for October, generated on 14 November, shows 40 of them with GST of ₹17,750.

The two missing bills are from the same distributor: one of ₹550 GST that the supplier will report next month, and one of ₹300 GST where the supplier typed the store's GSTIN wrong. The store claims ₹17,750 in October's GSTR-3B, asks the distributor to correct the GSTIN, and claims the remaining ₹850 in the month the bills appear in GSTR-2B. ₹17,750 + ₹550 + ₹300 = ₹18,600, so every rupee is accounted for.

GSTR-2B also showed one bill of ₹1,200 GST from a supplier the store never bought from. That record should be rejected in IMS and not claimed.

Common mismatches and what to do

What you see	Likely reason	What to do
In your books, not in 2B	Supplier has not filed, filed late or used a wrong GSTIN	Follow up with the supplier; claim when it appears
In 2B, not in your books	Bill not recorded, or not your purchase	Record it if genuine; reject in IMS if not
Amounts differ	Typing errors, discounts, rate differences	Agree the correct figure; supplier amends in GSTR-1A or a later GSTR-1
Shown as ITC not available	Blocked credit, time limit or place-of-supply issue	Check the reason column; do not claim

Common mistakes

Claiming credit from your purchase register instead of GSTR-2B
Ignoring GSTR-2B entries you do not recognise
Not chasing suppliers who file late until the year-end
Forgetting that credit for a year must be claimed by 30 November of the next year (or the annual return date, if earlier)
Not keeping a list of invoices claimed later, so they get claimed twice

How it shows up in returns

GSTR-2B feeds table 4 of GSTR-3B, the input credit you claim. Several GSTR-3B tables are now auto-populated from GSTR-2B, so the figure you see pre-filled is what the portal expects. Claiming more than GSTR-2B shows invites a notice asking you to explain the difference.

How TripleBill helps

In TripleBill, Tax → 2B Reconciliation takes the GSTR-2B JSON you download from the portal and shows which supplier invoices are matched, missing from your books or not yet filed, before you claim input credit (Starter and Pro).

How to match GSTR-2B with your purchase bills

1
Download GSTR-2B
After the 14th, open Returns → GSTR-2B on gst.gov.in for the period and download the JSON or Excel file.
2
Compare by GSTIN and invoice
Match each record against your purchase bills by supplier GSTIN, invoice number, date and tax amount, and list the differences.
3
Act in IMS
Accept matched records, reject ones that are not yours, and keep pending any you are still checking before you file GSTR-3B.
4
Claim and carry forward
Claim only what GSTR-2B supports, chase suppliers for missing invoices, and track the carried-forward bills so each is claimed once.

Frequently asked questions

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

GSTR-2A changes whenever a supplier files or amends; GSTR-2B is fixed for the period once generated. Use GSTR-2B for what you claim in GSTR-3B.

When is GSTR-2B available?

On the 14th of the following month for monthly filers, and after the quarter for QRMP filers.

Can I claim credit for a bill missing from GSTR-2B?

Not in that period. Claim it in the period it appears, within the time limit for the year.

Do I have to act on every invoice in IMS?

Records with no action are treated as accepted when GSTR-2B is generated, but rejecting wrong records protects you. Check the portal's current IMS guidance for any change.

Does GSTR-2B include reverse charge purchases?

It shows RCM supplies reported by registered suppliers. RCM on purchases from unregistered persons is worked out by you and does not appear there.

What if my supplier never files?

You cannot claim that credit. Talk to the supplier, and think twice before continuing to buy from someone who does not file.
