What Is GSTR-2B?
Most GST returns are something you fill in, but this one arrives already written.
GSTR-2B is a static, auto-drafted statement of the input tax credit available to a business for a tax period, built from what its suppliers have filed. It is generated once a month and never changes afterwards. That is exactly what makes it usable as the figure you claim against.
What Lands in It, and When
The statement is generated on the 14th of the following month and picks up the GSTR-1 filings your suppliers made up to the 13th, which you can see on the GST portal. Anything filed later waits for the next one.
Before that cut-off you get a say. The Invoice Management System lets you accept, reject or hold each invoice your suppliers have filed against your GSTIN, and those choices decide what flows through. Take no action at all and an invoice is treated as accepted.
Inside the statement, the entries are split in two:
- ITC Available, the part that feeds your return.
- ITC Not Available, covering invoices barred by the time limit and supplies where the credit is blocked outright.
GSTR-2B vs GSTR-2A
Both show supplier data, and only one of them is safe to claim against.
| Aspect | GSTR-2B | GSTR-2A |
|---|---|---|
| Nature | Static | Dynamic |
| Changes later | Never | Yes, as suppliers file |
| Arrives | 14th, once a month | Continuously |
| Used for | Claiming credit | Checking history |
A figure you took from GSTR-2A on the 16th can be different by the 25th, because late filings keep dropping into it. That is why the claim is pinned to the frozen statement instead.
GSTR-2B Example
A hardware distributor in Bilaspur reconciles the August 2026 period before filing.
| Source | Invoices | Credit |
|---|---|---|
| Your books | 46 | Rs.3,12,400 |
| In GSTR-2B | 43 | Rs.2,88,900 |
| Gap | 3 | Rs.23,500 |
Note: this is an invented example for illustration only. Your own gap depends on which suppliers filed on time.
Three invoices are real, booked and paid, and none of that helps this month. They are missing because those suppliers had not filed by the 13th, so the Rs.23,500 waits.
Why GSTR-2B Sets the Ceiling
Section 16(2)(aa) of the CGST Act ties the credit to the supplier having reported the invoice and it being communicated to you, which is the job this statement does. Rule 36(4) then limits the claim to what the statement shows.
The portal now enforces it rather than trusting you to. Since the April 2026 return period a GSTR-3B claiming more credit than the statement supports is simply not accepted, and a fuller lock on the credit table has been signalled without a dated advisory behind it, so check what your own return will let you do.
Whether a buyer should lose credit because a supplier defaulted has reached the courts more than once, which makes a missing invoice a supplier-chasing problem before it is an accounting one. An ITC reconciliation template run before the 13th is worth more than any amount of arguing after the 20th.
Track the GST Credits You Can Claim
Reconciliation moves at the speed of your purchase records, and that is the part sitting on your side of the fence.
For retail businesses, Petpooja Invoice helps you track GST credits and keeps GST reports for compliance and auditing purposes, so the figure you compare against GSTR-2B is already to hand.
For restaurants, Petpooja POSS keeps consumption visible with item-wise auto deduction and day-end reports, while GST billing for restaurants covers the outward half of the same return.
If your month-end starts with rebuilding a purchase list, the reconciliation never gets done before the 13th. An ITC calculator will size the gap; only cleaner records will close it.
Frequently Asked Questions
GSTR-2A keeps changing as suppliers file, while GSTR-2B is frozen the moment it is generated. Claims are made against the frozen one, because a figure that moves cannot be reconciled against a return you have already filed.
On the 14th of the month following the tax period, covering supplier filings up to the 13th. Quarterly filers under QRMP get one for the quarter instead.
In practice, no. Section 16(2)(aa) conditions the credit on the supplier reporting the invoice, and since the April 2026 period the portal blocks a return claiming more than the statement shows.
The invoice is treated as accepted and flows into your GSTR-2B. Doing nothing is a decision, so a wrong invoice left alone becomes credit you have to reverse later.
