For foreign companies engaging with Vietnamese partners, deploying staff to Vietnam or licensing technology and services into the market, determining whether a permanent establishment exists is a critical tax consideration. An incorrect assessment can result in unintended exposure to Vietnamese corporate income tax, along with associated penalties and unanticipated compliance obligations.
This guide walks through how Vietnam defines permanent establishment, when Foreign Contractor Tax (FCT) applies, how to reduce FCT exposure using double tax agreements and how contract structure influences the overall tax position.
Key takeaways
- Vietnam’s CIT Law defines permanent establishment as a fixed place of business, a dependent agent or a services presence lasting 183 days or more.
- FCT applies to most cross-border payments from Vietnamese entities to foreign companies, regardless of where the services are physically performed.
- A valid double tax agreement can eliminate the CIT component of FCT, but only if the foreign company does not have a PE in Vietnam and meets documentation requirements under Circular 80/2021/TT-BTC.
- Contract structure directly affects both PE risk and applicable FCT rates, depending on how the scope, location and nature of services are defined.
What is permanent establishment in Vietnam?
Permanent establishment (PE) is a tax concept that determines whether a foreign company has a sufficient presence in Vietnam to be subject to Vietnamese corporate income tax (CIT) on a net-profit basis. Under Vietnam’s CIT law, a PE is defined as a fixed place of business through which a foreign enterprise carries out all or part of its income-generating activities.
PE matters for two main reasons. First, the existence of a PE prevents a foreign company from claiming exemption from the CIT component of FCT under most double tax agreements (DTA). Second, the existence of a PE may create broader obligations to register for tax, maintain Vietnamese accounting records and file CIT returns on a net-profit basis.
Common triggers of permanent establishment
Vietnam’s CIT Law sets out several circumstances in which a foreign company can create a PE. Understanding these is essential before deploying staff, appointing agents or commencing service delivery. Common triggers include:
Fixed place of business
A PE arises where a foreign enterprise operates through a fixed location such as a branch, office, factory or warehouse, including projects exceeding the duration of thresholds. A home office may qualify if used for core activities.
Dependent agents
A PE may exist where a dependent agent in Vietnam habitually concludes contracts or acts on behalf of the foreign company, including contractors in substance.
Services presence
Services PE may arise where a foreign enterprise provides services in Vietnam for 183 days or more within any 12-month period. This threshold is cumulative across projects, meaning multiple short-term visits by employees can trigger a PE.
Remote work
An employee or contractor working remotely from Vietnam on an ongoing basis may create a PE if conducted from a fixed location with core functions or authority behalf of the company.
Digital and e-commerce
Foreign companies serving Vietnamese customers via e-commerce platforms or digital channels create a PE under the updated CIT Law, even without physical presence.
Preparatory or auxiliary activities, use of independent agents and services performed entirely outside Vietnam typically do not create a PE under most DTAs.
How Foreign Contractor Tax works in Vietnam
Foreign Contractor Tax (FCT) is Vietnam’s withholding tax on cross-border payments to foreign entities, with the Vietnamese payer responsible for deduction and remittance. A more detailed overview is available in our comprehensive guide on FCT in Vietnam.
FCT comprises two components: VAT and CIT for foreign entities, or VAT and Personal Income Tax (PIT) for foreign individuals. It applies to payments for services, royalties, interest, construction and installation, equipment leasing and certain goods transactions, regardless of where services are performed.
FCT generally applies if a Vietnamese entity contracts with a foreign party, unless an exemption applies. Limited exemptions include pure goods sales with title transfer at the border and services performed and consumed entirely outside Vietnam. If any services are delivered in Vietnam, FCT may apply to the full contract value.
FCT payment methods
There are three ways a foreign contractor can account for FCT, each with different eligibility conditions and practical implications.
| Method | Key features | Typical use case |
|---|---|---|
| Direct (deemed) | Tax calculated on gross revenue at fixed deemed rates; withheld and remitted by the Vietnamese payer; no local tax registration or accounting required | Default method for most foreign contractors |
| Declaration (VAS) | Requires PE, contract ≥183 days, tax registration and Vietnamese accounting; CIT at 20% on net profit; VAT under credit method | Long-term or established operations in Vietnam |
| Hybrid | VAT under credit method; CIT at deemed rates; requires same eligibility as Declaration method but without full VAS accounting | Contractors meeting PE/registration conditions but seeking simplified CIT treatment |
FCT rates by activity type
Under the Direct Method, FCT rates are expressed as a percentage of gross contract revenue, with rates determined by the nature of the activity. From 1 July 2025, the VAT component is governed by Circular 69/2025/TT-BTC, which replaced the VAT provisions of Circular 103/2014/TT-BTC. The CIT component continues to be governed by Circular 103/2014/TT-BTC.
| Activity type | Deemed VAT rate | Deemed CIT rate |
|---|---|---|
| Trading (goods with associated services) | 1% | 1% |
| Services (general) | 5% | 5% |
| Services via e-commerce or digital platforms | 10% | 5% |
| Restaurant, hotel, casino management | 5% | 10% |
| Leasing of machinery and equipment | 5% | 5% |
| Construction and installation (with materials) | 3% | 2% |
| Construction and installation (without materials) | 5% | 2% |
| Transportation | 3% | 2% |
| Transfer of technology, software, IP rights | Exempt | 10% |
| Royalties | Exempt | 10% |
| Loans and interest | Exempt | 5% |
| Reinsurance ceded abroad | Exempt | 0.1% |
| Securities transfer | Exempt | 0.1% |
Only the CIT component of FCT may be reduced or eliminated under a DTA. The VAT component remains payable under domestic rules and cannot be reduced by treaty.
A common compliance issue involves the boundary between services (5% CIT) and royalties or technology transfer (10% CIT). Payments that involve the licensing of intellectual property, know-how or software are typically classified as royalties, even if the contract describes them as service fees. Misclassification leads to underpaid tax, penalties and interest, so fee classification and contract drafting warrant attention from the outset.
Using double tax agreements to reduce FCT
Vietnam has double tax agreements with more than 80 jurisdictions, including Singapore, Japan, South Korea, the United Kingdom, Germany, France, China, Hong Kong and most ASEAN member states. Under the Business Profits Article 7, Vietnam cannot tax a foreign company’s profits if it does not have a PE in Vietnam and is a tax resident of a treaty country. In such cases, the CIT component of FCT may be eliminated or reduced, but VAT remains payable.
Practical application
A foreign company providing services to a Vietnamese customer can claim exemption from the deemed CIT portion of FCT if it has no PE in Vietnam and meets the documentation requirements. This relief applies in practice through withholding adjustments or refund procedures.
Key limitations
Treaty relief is not available if a PE exists. The foreign company must be the beneficial owner of the income and is required to submit the prescribed documentation on time. The treaty rate may apply depending on the specific DTA and the nature of the income.
Classification and treaty rates
Treaty rates on royalties, dividends and interest often differ from the domestic FCT rates. Treaties with Japan, South Korea, Singapore and EU member states reduce royalty withholding to rates of 5% to 10%, compared to the domestic 10% deemed rate. Correct classification is critical, as payments for technical services are treated differently from royalties and the characterisation depends on whether there is a transfer of IP, a licence or a pure service arrangement.
Claiming DTA benefits: documentation and process
Claiming a DTA exemption or reduced rate in Vietnam requires a formal application under Circular 80/2021/TT-BTC, supported by prescribed documentation and approval from the relevant Vietnamese tax authority. To claim treaty benefits, the following documentation is required:
- Certificate of Tax Residency issued by the foreign company’s home tax authority, valid for the relevant period and properly certified or apostilled where required
- Form 01/HTQT (the application form for DTA benefits) submitted to the provincial tax authority, detailing the taxpayer, income, treaty provisions and beneficial ownership
- A copy of the contract between the Vietnamese and foreign parties, including any amendments
- Supporting documentation that no PE exists in Vietnam, where applicable
The tax authority generally issues a decision within 30 working days of receiving a complete dossier, extendable by 10 days. Applicants are notified of the outcome and reasons must be provided if the claim is rejected.
Applications should be submitted before the first payment, ideally at least 60 days in advance, to avoid withholding at domestic rates. Where tax has already been withheld, a refund may be claimed after approval, though processing can be lengthy.
How contract structuring affects the PE and FCT position
Contract structuring directly influences both PE exposure and the applicable FCT rates. Clear structuring at the outset can deliver the most value.
Separate offshore and onshore components
If a contract includes both offshore and onshore elements, these should be split with a clear scope and pricing. Offshore components genuinely performed outside Vietnam, with no in-country services, may fall outside FCT scope, while onshore components remain taxable. Without a clear separation, the full contract value may be subject to FCT. Fee allocation should also be reasonable and reflected consistently in invoicing and payment flows.
Accurate characterisation of payments
The classification of a payment as a service fee, royalty, technology transfer fee or loan determines the applicable FCT rate and the relevant DTA article. Contracts that bundle multiple elements need to allocate and describe each component clearly.
Contracts that describe royalty payments as service fees to obtain a lower FCT rate represent a common compliance risk. Where an arrangement involves the use of IP, know-how or proprietary technology, the characterisation of royalty will generally prevail regardless of contract labelling.
Managing the 183-day threshold
For service providers, the 183-day threshold for a services PE must be monitored on a cumulative basis across all projects and personnel. An extended in-country presence may warrant establishing a formal registered entity rather than risking an unintended PE and associated compliance obligations.
Gross versus net contract pricing
Contracts should state whether the agreed price is gross or net of Vietnamese taxes. If unspecified, amounts are treated as net and grossed up for FCT calculation, increasing the effective cost. Foreign businesses should negotiate contract prices on a gross basis or ensure the tax position is explicitly addressed in the contract.
Compliance obligations under FCT
Vietnam’s FCT regime places key compliance responsibilities on the Vietnamese contracting party. For a broader overview of key tax deadlines in 2026, refer to our Vietnam compliance calendar.
- The Vietnamese party is responsible for withholding FCT before making payment to foreign contractors under the Direct Method.
- Late withholding triggers a daily interest of 0.03% and may lead to administrative penalties.
- FCT must be declared on Form 03/NTNN and paid by the 20th of the following month for monthly filing or by the 30th day of the first month of the next quarter for quarterly filing.
- Required records include a copy of the contract, bank payment vouchers, FCT payment receipts, the foreign contractor’s business registration certificate and where applicable, the Certificate of Residency and Form 01/HTQT.
- Non-compliance may result in late payment interest and administrative fines of VND 5 to 20 million for incorrect or incomplete filings, with higher penalties for more serious breaches under the Law on Tax Administration.
Conclusion
Permanent establishment in Vietnam is a material tax risk for foreign companies with in-country staff, local representatives or service contracts with Vietnamese counterparties. FCT is similarly broad in scope and often misunderstood, applying to a wide range of cross-border transactions regardless of where services are performed.
These risks can be managed with proper planning. Clear contract structuring, careful monitoring of PE thresholds and timely use of double tax agreements can reduce FCT burden and avoid unexpected compliance obligations. As Vietnam expands its approach to taxing cross-border income, early assessment remains critical.
