GSTR-2B
GSTR-2B is a static, auto-generated monthly statement of Input Tax Credit that tells a recipient exactly how much ITC is available and eligible for a tax period.
GSTR-2B is the auto-drafted, static ITC statement the GST portal generates for a recipient each month under Rule 60. It draws on suppliers' GSTR-1, GSTR-5 and GSTR-6 filings and — from October 2024 — the Invoice Management System. Since Section 16(2)(aa), ITC can be claimed only if the invoice appears in GSTR-2B.
GSTR-2B is generated once per tax period and does not change afterwards, which is what makes it a reliable reconciliation anchor (unlike the dynamic GSTR-2A). It lists, invoice by invoice, the credit available to you and marks each line as eligible or ineligible. It is governed by Rule 60 of the CGST Rules, 2017.
Because Section 16(2)(aa) makes appearance in GSTR-2B a precondition for ITC, this statement is the single most important document in credit reconciliation. If your books show a credit that GSTR-2B does not, you must chase the supplier, not claim the credit. With the Invoice Management System live, your accept/reject actions now shape what GSTR-2B contains. In practice, month-end close now begins with downloading 2B and reconciling it before a single figure enters the return.
The Recoup angle: Recoup matches your purchase register against GSTR-2B line by line and flags every invoice that is in books but not in 2B before you file.
