4 Conditions — Section 16(2)
All 4 must be met simultaneously: (1) Valid tax invoice; (2) Goods/services received; (3) Tax paid by supplier — verified via GSTR-2B; (4) GSTR-3B filed by recipient. Miss any one = ITC ineligible.
GSTR-2B Only — Rule 36(4)
Since January 1, 2022, provisional ITC is eliminated. ITC only available on invoices in GSTR-2B — generated on 14th of each month. No supplier GSTR-1 = No GSTR-2B = No ITC, even with valid invoice.
Nov 30 Deadline — Section 16(4)
ITC must be claimed by earlier of 30 November or GSTR-9 filing date. FY 2025-26 → 30 Nov 2026. Filing GSTR-9 early permanently closes the window. After this: credit permanently lost.
180-Day Payment — Section 16(2)
Reverse ITC if supplier unpaid after 180 days from invoice date. Reverse in GSTR-3B Table 4(B)(2) + 18% p.a. interest. Reclaim in Table 4(D)(1) once paid. Track proactively from 150 days.
Rule 37A — Supplier Non-Filing
If supplier files GSTR-1 (invoice appears in GSTR-2B), you claim ITC, but supplier doesn't file GSTR-3B — reverse ITC under Rule 37A. Track vendor GSTR-3B compliance monthly. Reclaimable once supplier files.
IMS — Invoice Management System
Accept / Reject / Pending each supplier invoice in IMS before it flows to GSTR-2B. Budget 2025: credit note from supplier requires ITC reversal by recipient before supplier can reduce output tax. Review IMS monthly.
