You paid your MSME vendor on time. You received the goods. Yet you may still lose your GST input tax credit — because your vendor didn't file his returns.
There is a structural conflict sitting quietly in the books of every mid-to-large business that purchases from MSME vendors — and most finance teams have not properly addressed it.
On one side: Section 15 of the MSMED Act requires payment within 45 days of acceptance of goods or services. Miss this, and the unpaid amount attracts compound interest at three times the RBI bank rate. It also gets reported in MSME Form 1 filed with the MCA — a regulatory exposure that boards are increasingly uncomfortable with.
On the other side: Section 16(2)(aa) of the CGST Act makes ITC conditional on the supplier reflecting the invoice in GSTR-2B. If your MSME vendor does not file GSTR-1, files it late, or reports the invoice incorrectly, your ITC is at risk — even if you received the goods and paid on time.
The Core Tension
Pay within 45 days and lose ITC. Withhold payment to pressure GST compliance and attract MSMED liability. There is no clean answer. But there are practical ways to manage the risk.
The "Objection" Route Under MSMED Act — Does It Help?
Section 15 of the MSMED Act provides that if the buyer raises a written objection within 15 days of delivery regarding acceptance of goods or services, the 45-day clock starts only from the date the objection is resolved by the supplier.
Some businesses have explored treating GST non-compliance — non-filing of GSTR-1, incorrect invoice reporting, non-reflection in GSTR-2B — as a ground for "objection." In my view, this is a legally fragile position. The objection mechanism under the MSMED Act is intended to address disputes about the quality, quantity, or acceptance of the supply itself. Extending it to cover a vendor's tax compliance failures is a stretch that is unlikely to survive scrutiny before the MSME Facilitation Council or a court. I would not recommend it as a primary safeguard.
What Actually Works
The businesses that are managing this well are doing the following:
Vendor onboarding with GST compliance as a baseline conditionBefore onboarding any MSME vendor, verify active GSTR-3B filing history for the last 12 months. A vendor who has been irregular historically will almost certainly continue to be irregular. This is the single most effective filter.
Contractual indemnity clauseYour vendor agreement should include a clause requiring the supplier to ensure timely and accurate reporting of all invoices in GSTR-1, with an indemnity obligation for any ITC reversal, interest, or penalty arising from their non-compliance. This does not eliminate the risk — recovering from a small MSME is practically difficult — but it creates a documented right and a deterrent.
Monthly GSTR-2B reconciliation before payment releaseImplement a payment process where the GSTR-2B position is checked before final payment is released. Where an invoice is not yet reflected in 2B but payment is otherwise due, release payment but flag the vendor and follow up on GSTR-1 filing before the next payment cycle. This keeps you MSMED-compliant while creating a documented compliance trail.
IMS (Invoice Management System) as an early warning toolWith IMS now live, recipients can track which invoices are pending, accepted, or rejected in near real-time. Build this into your accounts payable process. Where an invoice is not visible in IMS within 7–10 days of supply, trigger a vendor communication immediately — well before the 45-day window closes.
Vendor rating and progressive blockingMaintain an internal GST compliance score for each vendor. Two consecutive months of non-filing or mismatch should trigger a formal warning. Repeated default should result in either removal from the approved vendor list or a shift to advance payment against proforma — which removes the MSMED credit period obligation entirely.
Withholding the ITC portion — is it advisable?Some businesses deduct the GST component from payments where the vendor has not filed and the ITC is not reflecting in 2B. This is commercially understandable but legally risky. The MSMED Act does not recognise this as a valid ground for partial payment, and the vendor can trigger MSME Facilitation Council proceedings for the withheld amount. A better approach is full payment with a formal written notice to the vendor demanding GSTR-1 compliance within a specified timeline, with the right to recover any ITC loss through future payment adjustments explicitly stated in the notice.
The Bigger Picture
This conflict reflects a legislative gap. The MSMED Act was designed to protect small businesses from cash flow stress caused by delayed payments. The GST law was designed to ensure tax is paid and matched at every level of the supply chain. Neither statute contemplated the other's compliance requirements.
Until Parliament or the GST Council creates a safe harbour for recipients where ITC loss arises solely due to a registered MSME vendor's filing default — perhaps by restoring ITC on proof of payment and supply, independent of GSTR-2B — this tension will persist.
In the interim, process discipline and contractual protection are your best tools.
