If input tax credit is the part of GST that protects your cash flow, GSTR-2B is the document that tells you how much of it you can actually claim. It is generated for you, but using it well takes a little understanding. Here's what GSTR-2B is, how it differs from related statements, and how to put it to work each period.

Quick answer
GSTR-2B is your auto-drafted statement of available input tax credit. Here's what it is, how it differs from other statements, and how to use it before filing.
GSTR-2B is an auto-drafted statement of input tax credit, generated for each registered taxpayer based on the documents your suppliers have reported. It tells you, for the relevant period, what credit is available to you and what is not, broken down so you can see the source of each entry. You don't create it — the system prepares it from supplier filings and other data — which makes it your reference point for how much credit you can rely on when you file.
GSTR-2B is often confused with GSTR-2A, but they behave differently. GSTR-2A is dynamic and keeps changing as suppliers file or amend their data, whereas GSTR-2B is static once generated for a period — it gives you a fixed snapshot. That stability is precisely what makes GSTR-2B useful for working out your claim, because the figures don't shift under you after you've reconciled against them. Use 2A to understand movement over time, and 2B as the settled basis for a given period.
Your eligible input tax credit is closely tied to what appears in GSTR-2B, because credit generally depends on your suppliers having reported the corresponding invoices. If a supplier hasn't reported an invoice, the credit may not show up as available to you even though you hold a valid invoice and have paid the tax. This is why GSTR-2B is more than an information document — it directly affects how much credit you can claim, and gaps in it translate into credit you may have to chase or defer.
The practical use of GSTR-2B is reconciliation. Before filing, compare it against your own purchase records: match invoices, identify entries that appear in your books but not in 2B, and note anything in 2B you don't recognise. Where invoices are missing, follow up with the supplier so they report or correct them. Doing this reconciliation each period, rather than at year-end, keeps differences small and manageable and ensures the credit you claim is properly supported.
The most common mistake is claiming credit purely on the strength of your own invoices while ignoring what GSTR-2B shows, which can lead to claiming credit that isn't yet available. Another is treating the dynamic GSTR-2A and the static GSTR-2B as interchangeable. A third is leaving reconciliation until late, by which time mismatches have piled up. Building a habit of reviewing GSTR-2B early each period, and resolving differences promptly with suppliers, avoids all three.
GSTR-2A is dynamic and keeps changing as suppliers file or amend data, while GSTR-2B is a static snapshot fixed once generated for a period. Because it doesn't shift after generation, GSTR-2B is the more reliable basis for working out your credit for that period.
Generally your eligible credit is tied to what appears in GSTR-2B, which depends on your suppliers reporting their invoices. If an invoice is missing, follow up with the supplier to report or correct it rather than assuming the credit is automatically available.
Use it to reconcile against your own purchase records before filing — match invoices, flag anything missing or unrecognised, and chase suppliers on gaps. Doing this every period keeps differences small and ensures the credit you claim is properly supported.
