Transport is one of the trickiest areas of GST because the tax often does not work the way it does for a normal sale — the customer, not the transporter, frequently pays it. Understanding whether you are a Goods Transport Agency, and whether reverse charge applies, is the key to invoicing transport correctly.
GTA vs an ordinary transporter
GST draws a sharp line here:
- A Goods Transport Agency (GTA) is a person who provides road transport of goods and issues a consignment note. The consignment note is what makes you a GTA.
- An individual truck owner or operator who transports goods without issuing a consignment note is not a GTA — and such transport of goods by road is exempt from GST.
So the humble consignment note is the pivot on which the entire tax treatment turns.
The 5% vs 12% choice for a GTA
A GTA that pays tax itself (forward charge) has a choice:
| Option | Rate | Input Tax Credit |
|---|---|---|
| Concessional | 5% | Not available to the GTA |
| Standard | 12% | Full ITC available to the GTA |
At 5% the GTA cannot claim ITC on its own inputs (fuel, spares, etc.); at 12% it can. Which is better depends on how much input tax the GTA incurs.
Reverse charge: when the recipient pays
For road transport by a GTA to specified recipients — which include registered persons, companies, partnership firms, factories and societies — the liability can fall on the recipient under the reverse charge mechanism (RCM), unless the GTA has opted for forward charge.
Under RCM:
- The GTA issues the consignment note and a bill without charging GST, noting that tax is payable by the recipient under reverse charge.
- The registered recipient pays the GST (generally 5%) directly to the government and, subject to conditions, claims it back as ITC.
A GTA can opt out of RCM by choosing forward charge for the financial year and declaring so — after which it charges GST on its invoices in the normal way.
What a transport invoice / consignment note contains
A GTA’s documentation should include:
- GTA’s name, address and GSTIN
- Consignment note number and date
- Consignor (sender) and consignee (receiver) details
- Origin and destination
- Description, quantity and weight of goods
- Gross vehicle number
- Freight amount (taxable value)
- The GST position — either the GST charged (forward charge) or a clear note that “tax payable by recipient under RCM”
- The applicable SAC code (9965)
Intra-state vs inter-state
As with any service, if the transporter and recipient are in the same state it is CGST + SGST; if in different states, IGST. For RCM, the recipient applies the same intra/inter-state logic when computing the tax to be self-paid.
A quick example (RCM)
A factory (registered) hires a GTA to move goods; freight is ₹20,000, RCM applies:
- Freight (taxable value): ₹20,000
- GTA’s bill: ₹20,000, marked “GST payable by recipient under RCM”
- The factory self-pays GST @ 5% = ₹1,000 to the government
- The factory claims ₹1,000 as ITC (subject to conditions)
Common mistakes
- Assuming all transport is exempt — it is not once a GTA issues a consignment note.
- A GTA charging 5% GST and claiming ITC — the 5% option comes without ITC.
- Forgetting the RCM note on the bill, leaving the recipient unsure who pays.
- Mixing up e-way bill and consignment note — the e-way bill is a separate compliance for moving goods over ₹50,000, not the tax invoice.
The bottom line
If you issue consignment notes you are a GTA: decide between 5% (no ITC) and 12% (with ITC), and understand that for most business customers the tax may fall on them under reverse charge unless you opt for forward charge. Always state the GST position clearly on the consignment note and quote SAC 9965.
