Foreign shipping lines and airlines rarely have a direct presence in Vietnam, yet every shipment in and out generates freight revenue here. The contractor tax regime for international transport is purpose-built — its own ratio, a withholding channel through agents, and an unusually strong treaty relief layer for sea and air transport. This article presents all three elements.
Issue-by-Issue Analysis
The starting point is how Vietnam freight revenue is determined. For a shipping line, it is freight on cargo exported from Vietnamese ports and the inbound freight leg under the carrier responsibility per delivery terms; for aviation, freight and surcharges on the outbound leg from Vietnam. The Vietnamese agent — who actually collects from domestic shippers — is the natural data and withholding point, so the foreign carrier tax duties are in practice performed almost entirely through the agency system.
The second layer is treaties, and for international transport this layer is far stronger than for other services. The common rule in Vietnam treaties is that profits from international sea and air transport are taxable only in the carrier residence state. A carrier from a treaty country presenting a residence certificate and real transport operation records can be relieved of Vietnamese contractor CIT through the treaty application notification procedure — but the procedure must be done properly and in advance, not applied retroactively at will on an incomplete file.
For Vietnamese cargo owners, the point of attention sits in the sale contract delivery terms. Who charters the vessel and pays the freight decides whose hands the freight money passes through and where the withholding duty arises; a purchase where the foreign side arranges transport puts freight inside the goods price with tax handled through import valuation, while direct chartering by the Vietnamese side brings the contractor duty home. This is why the trade contract Incoterms must be read by the tax team together with logistics.
Applicable Legal Framework
- Contractor CIT on international transport: a 2% ratio on international freight revenue arising in Vietnam under the current contractor ratio table — the long-standing rate for foreign carriers without a permanent establishment.
- VAT on international transport follows the special mechanism for cross-border carriage, distinguishing direction of carriage and the performing party; the Vietnamese agent declares the relevant part per freight records.
- Enforcement channel: shipping and airline agents in Vietnam collect freight and perform withholding and payment on behalf of the foreign carrier per settlement cycle.
- Treaty layer: many Vietnamese double tax treaties and transport agreements reserve taxing rights on international sea and air transport profits to the carrier residence state, with real carrier conditions and a residence certificate required.
What the Business Should Do
- Vietnamese agents: set up a monthly or quarterly freight settlement and withholding cycle per foreign carrier, separating freight by direction and cargo type.
- Treaty-country carriers: prepare the residence certificate and treaty application notification file before the first Vietnamese filing period.
- Vietnamese cargo owners chartering directly: build contractor withholding on freight and surcharges paid to foreign carriers into the payment process.
- Archive complete transport records: bills of lading, freight statements, collection evidence and withholding receipts for per-carrier authority reconciliation.
Frequently Asked Questions
A foreign line has an agent in Vietnam — who pays the contractor tax?
In practice the Vietnamese agent collects freight, withholds and files on behalf of the line under authorisation and the tax administration rules for foreign contractors operating through agents. The tax obligation remains the line own; the agent is the enforcement channel responsible for its assigned part.
What conditions does treaty relief for sea transport need?
The carrier must be a resident of the treaty country, the international transport must be its own real operation, and the treaty notification file with the residence certificate must be submitted in proper procedure. Without the file, the authority applies the ordinary contractor regime until the file is accepted.
What if inbound freight is already inside the goods price?
Where the foreign side arranges transport and freight sits inside the import price, customs valuation handles the freight element under valuation rules; no contractor tax duty on freight arises for the Vietnamese buyer because there is no separate freight payment from Vietnam to the foreign carrier.
Do bareboat or time charters differ from freight?
Yes: bareboat and time charters are in substance asset leasing and transport organisation services, and may bear the contractor ratio of the services or leasing group instead of the 2% international transport ratio. Classifying the charter contract nature correctly is the first step before applying any ratio.
