Ship-To GSTIN Mandatory in GSTR One from June 15, 2026
From June 15, 2026, the GST Network (GSTN) is making the Ship-To GSTIN field mandatory in GSTR One for Bill-To/Ship-To transactions. If you ship goods to a location that belongs to a different registered entity (or a different state unit of the same buyer), you must now include the Ship-To party's GSTIN in your invoice and GSTR One entry. Incomplete entries will be rejected at the portal.
This change affects every manufacturer, trader, and e-commerce seller who fulfils orders where the billing address (buyer's registered office) and the delivery address (warehouse, branch, or consignee) are different.
What is a Bill-To/Ship-To Transaction?
A Bill-To/Ship-To transaction occurs when:
- Bill-To party: The registered buyer who places the order and pays the invoice
- Ship-To party: A different entity (or different registered location of the same buyer) where goods are physically delivered
Examples:
- A Hyderabad manufacturer (Bill-To) orders raw material; goods delivered to their Chennai factory (Ship-To). Same company, different state registrations.
- A Mumbai distributor (Bill-To) orders electronics; goods delivered directly to their retail store in Pune (Ship-To). Different GSTINs, different addresses.
- An e-commerce company (Bill-To) orders from a supplier; goods drop-shipped to end customer's warehouse (Ship-To). Entirely different entities.

Impact on ITC for Your Buyers
The Ship-To GSTIN requirement also protects your buyers' ITC claims. When the Ship-To GSTIN is correctly populated:
- The invoice appears in the GSTR TwoB of the Ship-To entity (not just the Bill-To entity)
- The Ship-To entity can claim ITC on goods received at their location
- Without the Ship-To GSTIN, ITC may appear only in the Bill-To entity's GSTR TwoB, even though physical receipt is at the Ship-To location, creating an ITC mismatch for the buyer
Frequently Asked Questions
Q: Does this apply to service invoices?
A: This change is primarily for goods transactions with physical shipment to a different location. Service invoices with a different "Place of Supply" follow the existing IGST rules and are not affected by this Bill-To/Ship-To Ship-To GSTIN requirement.
Q: What if the Ship-To party is unregistered (no GSTIN)?
A: If goods are delivered to an unregistered entity, leave the Ship-To GSTIN blank. The mandatory requirement only applies when the Ship-To location belongs to a registered taxpayer.
Q: We ship to our own warehouse in another state. Which GSTIN do we enter?
A: Enter your own branch GSTIN for that state. This correctly routes the ITC to the receiving branch and avoids an ITC mismatch in GSTR TwoB reconciliation.
Q: Can I amend past GSTR One entries to add Ship-To GSTIN?
A: Yes. GSTR One amendments (Table 9A/9B) allow corrections to invoices from prior tax periods. If you have pending Bill-To/Ship-To entries without Ship-To GSTIN, amend them before they cause buyer ITC mismatches.
