GST Compliance Alert — June 2026
What this article covers: From June 15, 2026, the GSTN makes the “Ship-To GSTIN” field mandatory in all Bill-To/Ship-To e-Way Bills. Miss it, and your EWB fails at generation. At the same time, the IMS “Deemed Acceptance” rule quietly locks wrong invoices into your GSTR-2B if you do not act. This article breaks down exactly what changes, the legal provisions behind it, real-world examples, the penalty exposure, and the precise steps every business must take before the deadline.

Quick Snapshot: Understand Everything in 2 Minutes
Before going deep, here is the full picture through one example. Read this once and the rest of the article will feel obvious.
The Scenario: A Purchase Order That Splits Bill and Delivery
Reliance Industries (Delhi HQ, GSTIN: 07XXXXX) places an order with Tata Steel (Mumbai). The invoice goes to Delhi. However, the goods travel directly to Reliance’s Surat factory (GSTIN: 24XXXXX). This is a classic Bill-To / Ship-To transaction.
Until now, while generating the e-Way Bill for this shipment, the “Ship-To GSTIN” field (the Surat factory’s GSTIN: 24XXXXX) was optional. Tata Steel could leave it blank and the EWB still generated successfully.
From June 15, 2026: that blank field blocks e-Way Bill generation entirely. The system refuses to proceed until the Ship-To GSTIN is filled. If the Surat factory is unregistered under GST, the supplier must type “URP” in that field. There is no third option.
Now add the second layer. Reliance’s finance team is busy. They open the GST portal at month-end and see 50 new invoices in their IMS (Invoice Management System) dashboard. They do not act on any of them. They simply file GSTR-3B as usual. What happens? All 50 invoices are automatically deemed accepted and flow into GSTR-2B as eligible ITC.
The Trap: If even 3 of those 50 invoices belong to a different company (wrong GSTIN) or carry an inflated amount, Reliance has now claimed wrong ITC. The system accepted it on their behalf. When the GST department runs its analytics, a mismatch notice (DRC-01C) arrives. Reversal with 18% annual interest under Section 50 of the CGST Act follows.
That combination, a mandatory field on the supply side and a silent acceptance on the purchase side, is precisely what this article unpacks. Both changes come from the same GSTN push: tighter tracking, less fraud, and more accountability at every step of the supply chain.

Part IThe Mandatory Ship-To GSTIN Field in E-Way Bills
What Is a Bill-To / Ship-To Transaction?
In simple terms: the buyer and the delivery address are different entities, or different GST registrations of the same entity.
Example 1: A company’s Head Office in Delhi (GSTIN: 07XXXXX) raises a Purchase Order. Goods are delivered to its Mumbai warehouse (GSTIN: 27XXXXX). The invoice goes to Delhi. The goods go to Mumbai.
Example 2: A trader in Bengaluru (GSTIN: 29XXXXX) buys goods for a customer in Hyderabad who is unregistered. The invoice names the Bengaluru trader. The goods land in Hyderabad.
Both are Bill-To / Ship-To transactions. Both require the new mandatory field from June 15.
What Exactly Changes on June 15, 2026?
GSTN Advisory No. 661 (dated May 20/21, 2026, cited as both dates across official sources) introduces one mandatory rule for e-Way Bill Part A. The rule is simple:
| Situation at Delivery Point | What to Enter in Ship-To GSTIN Field |
|---|---|
| Delivery recipient has a GST registration | Their exact, active GSTIN (e.g., 24XXXXX for the Surat factory) |
| Delivery recipient is unregistered under GST | URP (literal uppercase text, mandatory) |
| Field left blank | EWB generation blocked by portal |
The NIC has already released updated API specifications in the sandbox environment. All ERP vendors, GST Suvidha Providers (GSPs), Application Service Providers (ASPs), and system integrators must complete configuration changes before June 15.
Legal Backing: Rule 138 and Why This Field Matters
Rule 138(1) of the CGST Rules, 2017 governs Form GST EWB-01 (Part A). It requires the GSTIN of the recipient at the billing address. The new advisory extends this discipline to the Ship-To address as well. The intent is direct: match e-Way Bill data with GSTR-1 and GSTR-3B at every delivery point.
If the Ship-To GSTIN on the EWB does not match the recipient’s GSTIN on the tax invoice, the discrepancy becomes a direct flag for scrutiny. In complex supply chains, this is the most common reconciliation gap that triggers departmental inquiries.
Applicable Penalty Provisions. Section 122 of the CGST Act applies in two branches: (a) non-fraud cases: Rs 10,000 or 10% of the tax due, whichever is higher; (b) fraud or wilful misstatement cases: Rs 10,000 or 100% of the tax due, whichever is higher. Section 129 governs detention and seizure of goods and the vehicle in transit. Section 130 covers confiscation of goods. These provisions apply wherever the movement of goods does not match valid documentation.
Who Must Act Before June 15?
ERPAdd Ship-To GSTIN as mandatory field in EWB generation module
APIPull updated NIC sandbox specs; test before June 10
OpsVerify GSTIN of every Ship-To location in customer master
FinanceTrain staff on URP entry rule for unregistered recipients
SupplyAlign invoicing data with actual EWB destination for each leg
Part IIThe New Voluntary E-Way Bill Closure Facility
What Problem Does This Solve?
Until now, an e-Way Bill stayed “open” in the system even after goods reached the destination. Validity expired eventually, but there was no formal way to mark a delivery as complete. This created ghost trails: the system had no way to confirm whether a shipment ended or was still in transit. The gap caused reconciliation problems during GST audits and left room for EWBs to be misused after actual delivery.
From June 15, 2026, any of the following authorized persons can formally close an e-Way Bill after delivery:
| Who Can Close | How | Method Options |
|---|---|---|
| Supplier (logged in) | Portal login | EWB-wise or date-wise |
| Recipient (logged in) | Portal login | EWB-wise or date-wise |
| Transporter (logged in) | Portal login | EWB-wise |
| Driver / Authorized Person | Mobile OTP linked at EWB generation | Mobile number search + OTP |
| API Integrators | Via API with prescribed fields | System-to-system |
The closure window is strict: same day of delivery or the immediately following day. You cannot close it later. You cannot close it before delivery either.
Why Adopt This Voluntarily? Closing EWBs after each delivery builds a clean digital audit trail. It signals to tax authorities that your goods movement data aligns with actual deliveries. In complex multi-leg supply chains, closed EWBs dramatically reduce dispute risk during inquiries. Early adoption is strongly advisable even though legal compulsion does not exist today.
Cancellation vs. Closure: A Critical Distinction
| Aspect | Cancellation | Closure (New) |
|---|---|---|
| Purpose | Correct an error before transit begins | Confirm delivery completion after transit ends |
| When to Use | Within 24 hours of generation, if goods not yet moved | Same day or next day after successful delivery |
| Who Can Do It | Generator of the EWB only | Supplier, recipient, transporter, or driver |
| Status After | EWB treated as never existed | EWB marked as delivered and closed |
Part IIIThe IMS Deemed Acceptance Trap
What Is IMS and Why Does It Exist?
The Invoice Management System (IMS) is a dashboard on the GST portal where every B2B invoice, debit note, and credit note uploaded by your supplier in their GSTR-1 appears automatically. You, as the recipient, must decide what to do with each record before filing your GSTR-3B.
IMS became the statutory basis for ITC from October 1, 2025. Notification 16/2025-Central Tax (dated September 17, 2025) brought into force the Finance Act, 2025 amendment to Section 38 of the CGST Act, 2017. That amendment replaced the words “auto-generated statement” with “statement,” aligning the law with IMS and adding a new clause (c) to allow the government to prescribe additional ITC statement details. The practical consequence: ITC is now tied to accepted IMS records, not merely auto-populated GSTR-2B data. The Zero Mismatch hard block, which makes this impossible to ignore in practice, came into effect from April 1, 2026.
The Three Actions You Can Take
| Action | What Happens | ITC Flows to GSTR-2B? |
|---|---|---|
| Accept | You confirm the invoice is correct and goods / services received | Yes, ITC flows fully |
| Reject | You dispute or deny the invoice for that period | No; ITC blocked for that period |
| Pending | You need time to verify (credit notes: one period maximum) | No; ITC waits until you accept |
| No Action | Deemed Accepted automatically | Yes, ITC flows as if accepted |
What Is “Deemed Acceptance” Exactly?
If you take no action on an invoice before filing GSTR-3B, the system treats it as accepted automatically. This is deemed acceptance. The invoice enters GSTR-2B and ITC flows into your GSTR-3B. For genuine invoices, this is harmless. For wrongly issued or fraudulent ones, it locks incorrect ITC into your return without your conscious approval.
Real Example: The Silent Accept Problem
Situation: Rakesh runs a manufacturing business in Pune. In June 2026, 120 invoices appear in his IMS dashboard. He is busy and does not log in to act on them. On the 20th, his accountant files GSTR-3B. All 120 invoices are deemed accepted.
The Problem: Three of them are from a vendor who used Rakesh’s GSTIN by mistake, intended for a different buyer. Rakesh has now claimed ITC on Rs 6 lakh worth of goods he never received.
The Consequence: When the audit flags this mismatch, Rakesh must reverse that ITC with 18% annual interest under Section 50 of the CGST Act. The system accepted it on his behalf; the law still holds him responsible.
The Zero Mismatch Policy: The New Hard Block
From April 2026, the GST portal enforces a Zero Mismatch Policy under amended Rule 60 of the CGST Rules. If the ITC you try to claim in GSTR-3B (Table 4A) exceeds what appears in GSTR-2B, the portal blocks your return filing entirely. You cannot submit GSTR-3B until you resolve the difference. No override. No exception.
What Changed and When: A Clear Timeline
October 14, 2024: IMS goes live on GST portal; actions open to taxpayers. First IMS-based GSTR-2B generated November 14, 2024.
October 1, 2025: Section 38 amended via Finance Act, 2025 (Notification 16/2025-CT). ITC legally tied to IMS records, not just auto-populated GSTR-2B. Credit notes capped at one-period pending status. Rule 67B inserted for supplier liability on rejected credit notes.
April 1, 2026: Zero Mismatch hard block enforced. GSTR-3B filing blocked if ITC claimed exceeds GSTR-2B. IMS effectively unavoidable for all registered taxpayers from this date.
The One-Period Pending Limit for Credit Notes
Earlier, you could keep a credit note in “Pending” status indefinitely. That changed from October 2025. Credit notes and specified downward amendments can now be kept pending for only one tax period.
| Filer Type | One Pending Period Means | Deadline to Accept or Reject |
|---|---|---|
| Monthly filer | One calendar month | By GSTR-3B due date of the next period |
| Quarterly (QRMP) | One quarter | By GSTR-3B due date of the next quarter |
If you do not act within this window, the credit note is automatically deemed accepted. This reduces your ITC or increases reversal without your explicit decision.
Common IMS Mistakes to Avoid
| Mistake | What Goes Wrong | Risk Level |
|---|---|---|
| Using Rejection as a routine clean-up tool | Blocks ITC for the period. Genuine invoices lose credit until the supplier corrects and resubmits via GSTR-1A | High |
| Acting on an amendment before the original | Portal silently blocks the action; ITC reconciliation fails | High |
| Forgetting to click “Recompute GSTR-2B” after the 14th | Earlier draft stays visible; filed GSTR-3B uses stale ITC data | Medium |
| Ignoring the dashboard entirely (relying on deemed acceptance) | Fraudulent or wrongly addressed invoices flow into GSTR-2B unchecked | High |
| Letting credit notes exceed the one-period pending limit | Auto deemed-accepted; unintended ITC reversal | Medium |
Part IVHow Ship-To GSTIN and IMS Connect
These two changes look separate. They are actually two sides of the same enforcement upgrade. Together, they give GSTN a complete, end-to-end chain for every B2B transaction involving goods movement.
| Stage | Data Captured | Tool Used |
|---|---|---|
| Goods leave supplier | Ship-To GSTIN confirmed in e-Way Bill | EWB Portal (mandatory June 15) |
| Goods in transit | Movement tracked via EWB validity and vehicle number | EWB Portal |
| Goods delivered | EWB formally closed (optional but advisable) | EWB Closure Facility |
| Invoice processed by buyer | Accept / Reject / Pending action on IMS | IMS Dashboard |
| ITC claimed | Only accepted invoices flow to GSTR-2B | GST Return Filing |
The Enforcement Logic
If any step in this chain breaks, the system flags it. A Ship-To GSTIN mismatch between the EWB and the tax invoice triggers Section 129 scrutiny during transit. An IMS mismatch triggers DRC-01C notices and ITC reversals post-filing. The government is essentially building a closed loop: goods must go where the invoice says they go, and the buyer must consciously confirm receipt. Both steps are now verifiable, and both are now enforced.
Part VPractical Action Plan Before June 15, 2026
| If You Are… | Key Actions | Priority |
|---|---|---|
| ERP / Tech team | Pull updated NIC sandbox API specs immediately. Add Ship-To GSTIN as a mandatory field with validation (valid GSTIN format or “URP” only). Complete sandbox testing before June 10. | Urgent |
| Finance / Compliance team | Audit customer and location master; confirm GSTIN or URP status for every Ship-To location. Set weekly IMS review reminder before the 14th of each month. Never file GSTR-3B without reconciling IMS against the purchase register. | Urgent |
| Drop-shipment / Multi-leg supply chain | Generate a separate EWB for each leg with the correct Ship-To GSTIN for that leg’s destination. Align invoice data with EWB data at every leg. Mismatches at any leg invite detention under Section 129. | Urgent |
| Buyers receiving credit notes | Do not leave credit notes in pending status beyond one tax period. Act within the window to avoid automatic deemed acceptance and unintended ITC reversal. | High |
| All businesses (EWB Closure) | Adopt the voluntary EWB Closure feature from June 15. Close each EWB on the delivery day or the next day. It takes under 2 minutes and protects you in every future audit. | High |
Part VIPenalty and Risk Summary
| Non-Compliance Scenario | Applicable Provision | Consequence |
|---|---|---|
| EWB generated without Ship-To GSTIN after June 15 | Portal block + Rule 138 CGST Rules | EWB generation fails; goods cannot legally move |
| Goods moved with incomplete or mismatched EWB documentation | Section 122 CGST Act | Non-fraud: Rs 10,000 or 10% of tax due (higher). Fraud / wilful: Rs 10,000 or 100% of tax due (higher) |
| Goods detained in transit for EWB non-compliance | Section 129 CGST Act | Detention and seizure of goods and vehicle; penalty is 200% of tax payable (owner comes forward) or 50% of goods value less tax paid (owner does not) |
| Confiscation of goods for serious EWB violations | Section 130 CGST Act | Goods confiscated; fine in lieu of confiscation may apply |
| Wrong ITC claimed via deemed acceptance | Section 50 CGST Act | ITC reversal + 18% annual interest from date of availment |
| GSTR-3B ITC exceeds GSTR-2B (Zero Mismatch Policy) | Rule 60 CGST Rules | Return filing hard-blocked; cannot proceed until resolved |
| ITC claimed on demand notice after IMS mismatch detected | Sections 73 / 74 CGST Act | Demand notice + interest + penalty up to 100% in fraud cases |
Practical Compliance Checklist
- If you are a supplier with Bill-To / Ship-To transactions: Update your EWB system to make Ship-To GSTIN mandatory. Map every delivery location to its GSTIN or flag it as URP. Do this before June 15, not on June 15.
- If you are a buyer who has not reviewed IMS this month: Log in before the 20th. Match each invoice against your purchase register. Explicitly accept, reject, or pend each one. Never rely on deemed acceptance for any invoice you have not verified.
- If you are an ERP or API integrator: Pull the updated NIC sandbox API specs today. Add mandatory Ship-To GSTIN validation and complete testing by June 10 to leave a 5-day buffer.
- If you run a drop-shipment or multi-leg supply chain: Audit every EWB leg. Ensure Ship-To GSTIN for each leg matches the invoice destination. Mismatches at any single leg invite detention under Section 129.
- If you receive credit notes from vendors: Do not let them sit in pending status beyond one tax period. Act within the window to avoid automatic deemed acceptance and unintended ITC reversal.
- For everyone, starting June 15: Adopt the voluntary EWB Closure feature. Close each EWB on delivery day or the next day. It costs nothing, takes 2 minutes, and builds an audit trail that protects you in every future inquiry.
Closing Thoughts
These two changes, the mandatory Ship-To GSTIN and the IMS deemed acceptance framework, are part of GSTN’s bigger push toward a fully traceable, fraud-resistant supply chain. The government is essentially saying: every invoice must be anchored to a real delivery address, and every buyer must consciously confirm what they are accepting as ITC. That is fair.
The risk lies in assuming the system will handle it on your behalf. It will. But not always in your favour. A silent accept on a wrong invoice costs you far more in interest and notice-handling time than 15 minutes of monthly IMS review ever would.
Take action this week. Update your ERP, audit your Ship-To master, log into your IMS dashboard, and brief your logistics team. June 15 is days away, and there is no grace period once the portal enforces the block.
Frequently Asked Questions (FAQs)
It is mandatory only for Bill-To / Ship-To transactions, where the billing address and the delivery address are different. If your billing address and Ship-To address belong to the same GSTIN, this change does not affect your EWB generation workflow. However, if they differ, either as different GSTINs of the same entity or entirely different legal persons, the Ship-To GSTIN field becomes mandatory from June 15, 2026.
Enter URP (Unregistered Person) in the Ship-To GSTIN field. This is the only accepted value when the delivery recipient does not hold a GST registration. Leaving the field blank will block e-Way Bill generation entirely from June 15. There is no third option; the portal accepts only a valid GSTIN format or the literal text “URP.”
Currently, the portal allows it since the production rollout has not yet occurred. From June 15, the same action will fail at the portal level. Your EWB generation will be blocked. Therefore, fix your ERP and internal processes now, not on June 15. ERP changes and sandbox testing require lead time, and leaving this to the deadline date creates operational risk for your entire supply chain.
Yes. If you take no action before filing GSTR-3B, the invoice is deemed accepted and flows into GSTR-2B at the wrong amount. You should reject it in IMS before filing GSTR-3B. After rejection, your supplier can correct it via GSTR-1A in the same or a subsequent period and resubmit. You can then accept the corrected version in that period’s IMS cycle. Note that rejection blocks ITC for that period, so act on it promptly after the supplier confirms the correction is filed.
No. They serve entirely different purposes. Cancellation is for correcting errors before goods move; it must happen within 24 hours of EWB generation and can only be done by the EWB generator. Closure is for confirming that a delivery is complete after goods arrive; it can be done by the supplier, recipient, transporter, or driver within the same day or the next day after delivery. After closure, the EWB is marked as delivered. After cancellation, the EWB is treated as never having existed.
Not entirely. Deemed acceptance satisfies the invoice-reflection condition that ITC flowed from GSTR-2B as eligible credit. However, you still need to meet all other conditions under Section 16(2) of the CGST Act: actual receipt of goods or services, the supplier having paid the tax to the government, and the supplier having filed their returns. If the underlying supply is fake, the supplier has not paid tax, or the invoice belongs to a different buyer, deemed acceptance does not protect your ITC claim. The department can still raise a demand under Sections 73 or 74 with interest.
Yes. Both the Ship-To GSTIN mandate and IMS compliance operate per GSTIN registration. Each registration must independently update its EWB generation workflow and review its own IMS dashboard before filing GSTR-3B. For businesses with many GSTINs, this is precisely the scenario that makes automated IMS reconciliation tools necessary. Manually clearing hundreds of invoices per GSTIN in the 6-day window between GSTR-2B generation on the 14th and GSTR-3B filing on the 20th is operationally very difficult without automation.
Yes, but only before you file GSTR-3B for that tax period. You can change your IMS action as many times as needed until the moment of filing. Once GSTR-3B is filed, the action for that period is locked. After that, the supplier must correct the invoice via GSTR-1A for a subsequent period, and you can then accept the corrected version in that later period’s IMS cycle. This is why hasty rejections are costly: they require supplier action and a full cycle to reverse.
