The statutory boundary: Section 16(2)(b) receipt requirement

Under Section 16(2) of the Central Goods and Services Tax (CGST) Act, 2017, four core conditions must be satisfied before any registered taxpayer can claim input tax credit:

  1. Possession of a tax invoice or debit note issued by a registered supplier.
  2. Actual receipt of goods or services (Section 16(2)(b)).
  3. Tax charged in respect of the supply has been paid to the Government by the supplier.
  4. The recipient has furnished the return under Section 39 (Form GSTR-3B).

A supplier may upload an invoice in their GSTR-1 on the 8th of October for goods dispatched by truck on the 10th of October. If those goods do not arrive at your factory gate until the 22nd of October, you have not fulfilled condition (2) for the September/October cutoff period. Accepting that invoice on IMS prior to actual physical delivery creates a premature ITC claim that violates Section 16(2)(b).

What the Accept action does in IMS

When you mark an inward supply as Accept on the IMS dashboard:

  • The invoice is pushed directly into Table 4(A)(5) (All other ITC) of your generated Form GSTR-2B for the current tax period.
  • The tax amount auto-populates into Table 4(A)(5) of your Form GSTR-3B.
  • The invoice status locks for that month once GSTR-3B is filed.
  • The supplier IMS dashboard shows the invoice as Accepted.

You should only select Accept when you hold the original tax invoice, your store team has confirmed physical receipt of the material (via Goods Receipt Note or GRN), and the inward record matches your purchase register.

What the Pending action does in IMS

When you mark an invoice as Pending on IMS:

  • The invoice is excluded from your GSTR-2B for the current month. Zero credit flows to your GSTR-3B.
  • The document rolls over to the next tax period on your IMS dashboard. It stays accessible for future review.
  • The supplier's outward tax liability is not changed. The supplier pays their output tax as declared in GSTR-1.
  • In any future tax period, you can change the status from Pending to Accept (when goods arrive) or Reject (if the transaction is cancelled).

Payment on hold: Rule 37 180-day mechanics

Many commercial businesses withhold supplier payments pending project milestones, testing, or contract reconciliations. Accountants often ask: Should we mark an invoice as Pending on IMS if we are withholding payment to the vendor?

The answer depends on receipt of goods, not payment date:

If you have physically received the goods and verified the bill, you can accept the invoice on IMS and avail ITC in GSTR-3B, even if payment is on hold. The law gives you a statutory 180-day grace period:

  • Second Proviso to Section 16(2): The recipient must pay the supplier the value of the supply along with tax within a period of 180 days from the invoice date.
  • Rule 37 reversal: If you fail to pay within 180 days, you must reverse the ITC availed in Table 4(B)(2) of Form GSTR-3B for the month immediately following the 180-day expiration, along with interest under Section 50.
  • Re-claim upon payment: When you eventually release payment to the vendor, you can re-claim the reversed credit in Table 4(A)(5) and Table 4(D)(1) of GSTR-3B without any time limit restrictions under Section 16(4).

Therefore, if payment is delayed for normal commercial credit terms (such as 30, 45, or 60 days), Accept the invoice on IMS. Do not keep it Pending merely because the check has not been signed.

Decision matrix: Accept vs Pending vs Reject

Commercial Situation Physical Goods Status IMS Action Statutory Reason
Material in transit across state border Not yet received at warehouse Pending Condition of Section 16(2)(b) not satisfied. Premature credit is illegal.
Delivery complete, GRN signed Received and inspected Accept Full Section 16(2) compliance. Avail ITC in current GSTR-3B.
Delivery complete, payment withheld on terms Received Accept Protected by 180-day window under Section 16(2) second proviso.
Material delivered but failed quality test Rejected at factory gate Pending / Reject If returning entire lot, Reject. If negotiating debit note, Pending.
Invoice from unknown vendor (wrong GSTIN) No supply ever ordered Reject Bogus or erroneous bill. Rejection prevents audit queries.

Worked arithmetic example: transit timing

Review this timing calculation for an industrial equipment purchase:

Date / Event Details Financial Impact
28 September 2026 Supplier raises Invoice #842 for ₹5,00,000 + 18% IGST (₹90,000) and dispatches machinery. Supplier reports in GSTR-1 on 10 October 2026.
12 October 2026 Machinery still in transit. Recipient reviews IMS dashboard. Recipient marks Pending on IMS before 14 October cutoff.
14 October 2026 September GSTR-2B generated. ₹90,000 excluded from September GSTR-2B. ITC availed = ₹0.
19 October 2026 Truck reaches recipient plant. Store manager inspects and signs GRN. Section 16(2)(b) condition satisfied on 19 October.
10 November 2026 Recipient opens October IMS dashboard, finds Invoice #842 in Pending tab. Recipient changes status to Accept.
14 November 2026 October GSTR-2B generated. ₹90,000 correctly populates Table 4(A)(5) of October GSTR-2B.

By deferring through Pending, the company avoided claiming ₹90,000 in September before physical receipt. Had the company accepted in September, an audit cross-check between the transport e-way bill delivery timestamp (19 October) and September GSTR-3B would have triggered a demand for ₹90,000 plus interest under Section 50(3).

Summary checklist

  1. Always verify physical receipt against store GRN before clicking Accept on IMS.
  2. Use Pending for goods in transit or pending commercial debit notes.
  3. Do not use Pending for payment delays under 180 days; Accept the credit and manage payment terms separately.
  4. Review the Pending tab on IMS every month to ensure genuine credits are not forgotten.
