Place of Supply Under GST: Meaning and Manufacturer Guide

Place of supply under GST helps decide which tax applies to a transaction and which state receives the tax. For manufacturers, it matters because goods often move across states, are delivered to third parties, installed at customer sites, or dispatched through complex supply chains.

A wrong place-of-supply decision can affect invoicing, tax classification, returns, reconciliation, and compliance.

This article is for general operational education only. It is not GST, tax, legal, accounting, or compliance advice. GST rules change and practical treatment depends on facts, contracts, registration, supply type, and professional interpretation. Always consult a qualified GST professional before making tax decisions.

What Place of Supply Means

GST is destination-based. Place of supply generally helps identify where the supply is treated as consumed or delivered for tax purposes.

When the location of supplier and place of supply are in different states, IGST may apply. When they are in the same state, CGST and SGST may apply, subject to applicable GST rules.

Why Manufacturers Must Care

Manufacturers deal with physical goods, branch transfers, bill-to ship-to transactions, job work, installation at site, exports, imports, services, and transport documentation.

If the place of supply is wrong, the invoice may carry the wrong tax type. This can create problems for the supplier, recipient, and return filing.

Goods Involving Movement

For goods involving movement, the official CBIC text for Section 10 of the IGST Act states that the place of supply is linked to the location where movement terminates for delivery to the recipient. Official reference: CBIC Section 10.

In practical terms, if goods are shipped from Maharashtra to a recipient in Gujarat, the place of supply may generally be Gujarat, depending on facts and applicable rules.

Bill-To Ship-To Situations

Manufacturers often receive instructions where one party orders goods and asks delivery to another party. Such transactions need careful GST review because the tax treatment may depend on who is deemed recipient and what the contract says.

Do not handle these cases casually. Keep customer instructions, delivery details, GSTIN, state, and invoice records clean.

Goods Installed at Site

Where goods are assembled or installed at site, place of supply can depend on the place of installation or assembly under the relevant GST provisions.

This matters for machinery, equipment, fabricated structures, panels, and project-based manufacturing.

Services and Mixed Transactions

If a supply includes services, installation, maintenance, transport, or project execution, the analysis may become more complex. Place of supply for services has separate provisions and exceptions.

Manufacturers should not assume goods rules automatically apply to every transaction.

Operational Data Required

Good GST handling needs clean master and transaction data:

• Supplier location
• Customer GSTIN and state
• Ship-to address
• Bill-to address
• Delivery location
• Contract terms
• Dispatch documents
• Installation site where relevant
• Tax type applied
• E-way bill and invoice linkage

If this data is incomplete, compliance review becomes harder.

Practical Checklist

Before raising invoice, verify supplier state, customer GSTIN, bill-to address, ship-to address, actual delivery location, supply type, and whether installation or services are involved.

For unusual cases, pause and get professional advice before dispatch and invoicing.

Founder’s Note

AICAN’s founder-led view is that compliance quality depends heavily on operational data quality. If order, dispatch, and customer information are messy, tax teams are forced to clean up after the event.

A good system should help capture the right details before the invoice goes out.
