Taxes are a non-negotiable part of doing business, but foreign contractor tax in Vietnam is not triggered simply because a company is incorporated in Vietnam. In practice, foreign contractor tax, commonly called FCT, becomes relevant when a foreign organization or individual earns Vietnam-sourced income under a contract with a Vietnamese party, or when a Vietnamese party makes payments that fall within the FCT rules.
Vietnam has a defined legal framework for foreign contractor tax. The main substantive rules are still set out in Circular No. 103/2014/TT-BTC, while the declaration procedures and current forms are administered under the more recent tax administration framework, including Decree No. 126/2020/NĐ-CP and Circular No. 80/2021/TT-BTC.
Read on.
What is Vietnam’s Foreign Contractor Tax?
Vietnam’s foreign contractor tax applies to foreign business organizations with or without a permanent establishment in Vietnam, and to foreign business individuals whether resident or non-resident, if they do business in Vietnam or earn income in Vietnam under contracts, agreements, or commitments with Vietnamese parties. It is therefore broader than just “financial service provision agreements,” and it is not limited to foreign companies that already have a permanent establishment in Vietnam.
In practical terms, FCT usually applies to cross-border payments connected with services, services attached to goods, certain trading and distribution arrangements, domestic export structures, royalties, interest, construction and installation contracts, transportation, insurance, machinery and equipment leases, and other Vietnam-sourced income streams described in Circular No. 103/2014/TT-BTC.
Foreign contractor tax (FCT) applies to certain financial transactions or payments to foreign companies, such as:
- Lease rentals
- Insurance
- Transportation
- Transfer of goods and securities supplied within Vietnam’s borders or linked services provided in Vietnam
- Interest
- Construction, installation with/without the supply of materials, machinery or equipment.
- Royalties
- Service fees
FCT remains a legal requirement under Vietnamese law, primarily under Circular No. 103/2014/TT-BTC. However, the article’s original wording was too narrow and partly inaccurate: FCT can apply regardless of whether the foreign contractor has a permanent establishment in Vietnam, and the scope also covers a number of cross-border goods and distribution situations where Vietnam-sourced income arises.
We’ll discuss more on precise transactions that the foreign contractor tax applies to later in this article. First, let’s examine the nature of these taxes.
What kind of taxes are collected when paying foreign contractor tax in Vietnam?
Foreign contractor tax is not a standalone tax head. Instead, it is the mechanism under which Vietnam collects the relevant taxes from foreign contractors. In most business-to-business cases involving foreign organizations, the two main components are:
- Value-added tax (VAT)
- Income tax
Where the foreign contractor is an individual rather than an organization, personal income tax (PIT) may apply instead of CIT. That is why it is more accurate to say that FCT generally involves VAT plus either CIT or PIT, depending on the status of the foreign contractor.
VAT applies to services and services attached to goods that are provided by foreign contractors and used for manufacture, sale, or consumption in Vietnam, subject to the exclusions in Circular No. 103/2014/TT-BTC. CIT then applies to Vietnam-sourced income from the relevant goods, services, rights transfers, loan interest, securities transfers, compensation treated as taxable income, and other taxable income described in the Circular.
As such, it is essential to familiarize yourself with taxation laws in Vietnam.
What are some examples of taxable foreign corporation transactions in Vietnam?
The common deemed FCT rates under Circular No. 103/2014/TT-BTC are generally summarized as follows:
| No. | Items | CIT rate (%) | VAT rate (%) |
| 1 | Trading: Distribution or supply of goods, raw materials, supplies, machinery, and equipment; distribution of goods attached to services in Vietnam; and certain supply-of-goods arrangements under Incoterms | 1 | Commonly exempt on pure trading, but VAT may still apply to the service element where goods are attached to services or the contract is structured differently |
| 2 | Service, Lease of machinery and equipment, insurance, lease of an oil rig. | 5 | 5 |
| – Restaurant, hotel, casino management services | 10 | 5 | |
| – Derivative financial services | 2 | Exempt | |
| 3 | Construction and installation without supply of materials, machinery, or equipment | 2 | 5 |
| 4 | Construction and installation with supply of materials, machinery, or equipment. | 2 | 3 |
| 5 | Transportation, including sea and air transport | 2 | 3(1) |
| 6 | Transfer of securities, certificates of deposit, ceding reinsurance abroad, and reinsurance commission | 0.1 | Exempt |
| 7 | Loan interest | 5 | Exempt |
| 8 | Royalties | 10 | Exempt(2) |
| 9 | Other business activities | 2 | 2 |
Note:
(1) International transportation which is exempt from VAT.
(2) Software licenses, transfers of technology and intellectual property rights are exempt from VAT. Other royalties are likely subject to VAT
The article’s original rate summary was directionally useful, but businesses should not treat these percentages as a substitute for contract review. Circular No. 103/2014/TT-BTC makes clear that where a contract includes multiple business activities, the rates should be applied to each separable activity; if the values cannot be separated, the highest relevant rate may apply to the whole contract value, or composite construction and equipment rules may apply.
When do the tax obligations take effect, and what are the deadlines?
- The tax obligation generally arises when a Vietnam-sourced payment to a foreign contractor falls within the FCT regime. It is not accurate to state that there is always a tax-code registration deadline of the 10th day from signing the contract. Under the current GDT administrative procedures, direct-method FCT filing is generally made for each payment to the foreign contractor, and the filing deadline for each occurrence is no later than the 10th day from the date the tax liability arises. Where the Vietnamese party pays the foreign contractor multiple times in a month, monthly filing may be registered instead, with the filing deadline no later than the 20th day of the following month.
- The tax authority also maintains a separate substitute-tax-code registration procedure for organizations and individuals that withhold and pay tax on behalf of foreign contractors, so registration should be assessed by reference to the chosen method and payment structure rather than assumed from contract signing alone.
- In addition, contract-end tax finalization may be required depending on the filing route used. The GDT’s administrative procedures expressly refer to tax finalization when the contractor contract ends for both direct-method and certain direct-filing cases.
How to declare foreign contractor tax in Vietnam
Before declaring taxes, you should first determine which FCT method applies. Circular No. 103/2014/TT-BTC recognizes three methods:
- Deduction method
- Hybrid method
- Direct method.
The original requirement list in this article was inaccurate. The deduction or declaration method is available only if the foreign contractor or foreign subcontractor:
- has a permanent establishment in Vietnam or is a resident in Vietnam;
- conducts business in Vietnam under the contract for 183 days or more from the contract’s effective date; and
- applies Vietnam’s accounting practice, has tax registration, and has been issued a taxpayer identification number.
If those conditions are not met, the Vietnamese party generally withholds and pays tax on behalf of the foreign contractor under the direct method. The hybrid method is available where the foreign contractor satisfies the first two conditions and follows the accounting rules required for VAT credit-invoice treatment, while CIT continues to be paid on the deemed-rate basis.
Under the current tax administration forms, the GDT’s procedures refer to:
- Form 01/NTNN for foreign contractors paying VAT by the direct method on VAT and CIT by percentage on revenue;
- Form 02/NTNN for contract-end finalization in the direct method; and
- Form 03/NTNN for foreign contractors directly declaring VAT by the credit-invoice method and CIT by percentage on revenue.
Filings may be submitted directly to the tax authority, by post, or electronically through the tax authority’s portal if the electronic transaction requirements are satisfied.
Who actually files and pays FCT in practice?
One of the most important practical points missing from many older FCT articles is that the person who files and pays depends on the tax method. Under Circular No. 103/2014/TT-BTC, Vietnamese entities that purchase services, pay Vietnam-sourced income, or otherwise fall within the Circular can be required to withhold VAT and CIT before paying the foreign contractor or foreign subcontractor. In other words, for the direct method, the Vietnamese side is often the compliance gatekeeper. By contrast, where the foreign contractor qualifies for the declaration method or hybrid method, the foreign contractor may register and file directly with the tax authority instead of relying entirely on withholding by the Vietnamese customer. That distinction affects the registration approach, the filing forms, the internal approval flow, and the commercial negotiation of gross-up clauses and tax responsibilities in the contract.
It is equally important to understand that not every offshore contract is automatically taxable in Vietnam. Circular No. 103/2014/TT-BTC excludes certain pure goods sales where the seller’s responsibility ends at the foreign or Vietnam border checkpoint and there are no ancillary services performed in Vietnam beyond warranty. It also excludes services that are provided and used outside Vietnam. At the same time, the Circular specifically illustrates that some digital or remote activities, such as online advertising, online marketing, and online training consumed in Vietnam, can still fall within the FCT rules. That is why businesses should not rely on labels like “offshore service” or “foreign supplier” alone. The real analysis should focus on delivery terms, where the service is actually performed, where it is consumed, whether goods and services are bundled, and whether the foreign party keeps ownership, pricing control, or distribution responsibility in Vietnam.
Practical filing and treaty-relief checklist
A second compliance area often missing from general FCT articles is the interaction between routine filing, contract-end finalization, and treaty relief. The GDT’s current administrative procedures show that direct-method FCT is generally declared for each payment made to the foreign contractor, with a filing deadline no later than the 10th day from the date the tax liability arises. Where there are multiple payments in a month, monthly filing may be registered, with the monthly return due by the 20th day of the following month. The current procedures also refer to contract-end finalization for direct-method cases and prescribe specific forms under Circular No. 80/2021/TT-BTC. Businesses should therefore build an internal timetable around actual payment dates, not merely contract signing dates.
Treaty relief should also be checked early rather than after payments have already been made. Circular No. 103/2014/TT-BTC states that if an applicable double taxation agreement defines permanent establishment or residence differently, the treaty can prevail. The tax authority also maintains specific procedures for foreign contractors seeking exemption or reduction under a tax treaty, which means treaty relief is not automatic and requires a dossier to be filed with the competent tax authority. As a practical matter, businesses should review the contract before signature for tax gross-up language, whether prices are VAT- or CIT-inclusive, whether the values of goods and services are separately stated, whether subcontractors are properly listed, and whether supporting records prove that an exclusion or treaty claim is available. Those details directly affect the tax base because Circular No. 103/2014/TT-BTC also treats certain costs paid on behalf of the foreign contractor as part of taxable revenue.
Why does Vietnam have foreign contractor taxes?
Vietnam’s FCT regime is best understood as Vietnam’s source-based withholding and collection framework for foreign contractors earning Vietnam-sourced income. Because the rules depend heavily on contract terms, delivery structure, and where goods and services are performed or consumed, foreign contractor arrangements often require a contract-by-contract review rather than a one-size-fits-all answer.
Hence, foreign contracts often feature several taxable objects, and there’s a need to pay attention to specifics in each contract.
