A Vietnamese enterprise pays a foreign counterparty — software licence fees to a US company, service fees to a Chinese contractor, loan interest to a Singapore bank — and almost every payment attracts a withholding tax at source. In Vietnam it has its own name: foreign contractor tax (FCT). In China: withholding tax (预提所得税). The two mechanisms look alike but differ in rates, classification and the role of tax treaties. This comparison helps businesses in Vietnam–China supply chains avoid being taxed twice for nothing — and avoid the equally costly mistake of assuming the two systems work the same way.
The comparison matters most in two directions. Vietnamese companies paying Chinese suppliers and service providers must apply Vietnam's FCT correctly or face reassessment. Chinese-invested enterprises in Vietnam — and Vietnamese businesses paying into China — must navigate China's withholding system, where the statutory rate and the applied rate tell different stories. Get either direction wrong and the cost lands on the payer.
1. Vietnam: what is foreign contractor tax?
FCT is not a standalone tax — it is a collection mechanism for two taxes, VAT and CIT, applied to foreign organisations and individuals doing business in Vietnam or earning Vietnam-sourced income. From 1/7/2026, Circular 103/2014/TT-BTC was repealed (per Article 99 of Circular 89/2026/TT-BTC); filing procedures now follow Article 30 of Circular 89/2026/TT-BTC, with the tax base determined under current VAT and CIT law.
The key point: the duty to withhold, declare and pay lies with the Vietnamese payer. Signing with a foreign contractor while forgetting the clause "price inclusive or exclusive of FCT" is the most common mistake — disputes over who bears the tax typically erupt when the tax authority reassesses.
Deemed rates by income type (on deemed revenue):
| Income type | VAT | CIT |
|---|---|---|
| Ordinary services | 5% | 5% |
| Royalties | n/a* | 10% |
| Loan interest | n/a* | 5% |
| Goods with attached services | case-by-case | case-by-case |
*Per the Circular's precise wording: certain amounts fall outside VAT scope — check the instrument when applying.
The golden rule: classify the income correctly before applying the rate. A "software plus implementation services" contract may be split into several income streams at different rates — and the tax authority may reclassify if the allocation is unreasonable.
Worked example: a Vietnamese company pays USD 100,000 in consultancy fees to a Singapore contractor. If the contract price is stated exclusive of FCT: the contractor is entitled to the full USD 100,000, and the Vietnamese payer pays the tax itself on top — VAT = 100,000 × 5% = USD 5,000, CIT = 100,000 × 5% = USD 5,000, total USD 10,000, so the payer's total cost is USD 110,000. If the contract price is stated inclusive of tax (net): the Vietnamese payer withholds USD 10,000 from the USD 100,000 payment and the contractor nets USD 90,000 — the contractor economically bears the tax. The "price inclusive/exclusive of tax" clause is therefore the single most important negotiation point in the contract, not boilerplate.
For construction — where FCT arises thick and fast with each progress payment — see the tax handbook for foreign construction contractors in Vietnam (Vietnamese edition; English URL wiring pending at publish).
There is also a compliance dimension many payers discover too late. FCT is not just about the rate — it is about the filing. The Vietnamese payer must register the foreign contractor, file FCT returns per payment (or per period, depending on the method elected) and obtain withholding certificates. A payer that withholds the right amount but files incorrectly still faces penalties. Build the compliance workflow before the first payment, not after the first tax audit.
Contract drafting deserves equal attention. Every cross-border service or licence agreement should state whether the price is inclusive or exclusive of Vietnamese taxes, who bears the tax if rates or rules change, and who is responsible for providing the documents the other side needs for its home-country foreign tax credit. The classic dispute: a contract silent on tax, a 5%+5% withholding the Vietnamese payer must bear by law, and a foreign supplier refusing a price reduction. Allocate the burden in writing, before signing.
2. China: withholding tax on non-residents
China's Enterprise Income Tax Law taxes non-resident enterprises on China-sourced income. The mechanism: the Chinese payer withholds at source before remitting funds abroad.
On rates, two layers must be distinguished:
- Statutory rate: 20% on income of non-resident enterprises without an establishment in China.
- Rate in practice: many income types (dividends, interest, royalties) are commonly taxed at 10% under implementing rules.
This gap between "what the statute says" and "what is actually applied" is the most confusing point for Vietnamese businesses receiving money from or paying money to China — always check the implementing rules in force, not just the statute.
A further practical point: China's withholding system interacts with its invoice (fapiao) and foreign-exchange controls. The Chinese payer typically needs the withholding tax filing to release foreign exchange for the outbound payment — so treaty relief paperwork should be completed before the payment date, not after. Late paperwork does not just cost the treaty benefit; it can delay the payment itself.
3. Comparison table
| Criterion | Vietnam (FCT) | China (withholding tax) |
|---|---|---|
| Nature | VAT + CIT collection mechanism | CIT withheld at source |
| Taxable persons | Foreign organisations/individuals with Vietnam income | Non-resident enterprises with China income |
| Withholding agent | Vietnamese payer | Chinese payer |
| Rates | Deemed by income type (services 5%/5%, royalties 10% CIT, interest 5% CIT) | 20% statutory, commonly 10% in practice |
| Treaty role | CIT withholding relief if conditions met | Withholding relief if conditions met |
| Typical risk | Misclassifying income; forgetting tax clauses | Confusing statutory vs applied rates |
Reading the table as a decision guide: if you are the Vietnamese payer, your compliance burden is classification plus filing under Circular 103. If you are paying into or out of China, your burden is verifying which rate actually applies — statute, implementing rule or treaty — and completing the paperwork before the money moves. The two systems punish different mistakes, so staff handling Vietnam–China payments need both playbooks, not one.
4. The Vietnam–China double taxation agreement
Both countries have a DTA with each other. Its main effects here:
- Allocating taxing rights: which country may tax which income, avoiding both taxing the same income.
- Lowering withholding rates: treaties typically cap rates on dividends, interest and royalties below domestic law.
But treaty benefits are not automatic — the enterprise must complete treaty notification/relief procedures in the income-source country (usually through the payer's local tax authority), with a tax-residence certificate issued by the other country's tax authority. Skipping the procedure while self-applying treaty rates is an error that triggers reassessment.
In practice, the treaty procedure has its own timeline that must be built into payment planning. The tax-residence certificate — issued by the home country's tax authority — can take several weeks to obtain, and some Chinese local tax bureaus require the treaty filing to be completed before they will process the reduced withholding. For recurring payments (quarterly royalties, monthly service fees), set up the treaty filing once and keep it current, rather than scrambling before each payment. And keep the full paper trail: the treaty claim form, the residence certificate, the underlying contract — because a treaty benefit claimed without documentation is a treaty benefit waiting to be reversed in an audit. For a concrete illustration of how the treaty works in practice, see the Vietnam–China DTA case study on dividend tax relief (Vietnamese edition; English URL wiring pending at publish).
5. Practical checklist for businesses
Use this as a pre-payment checklist — run through it before the first cross-border payment under any new contract, not after the tax authority asks questions:
- Map cross-border cash flows: list every payment to/from foreign parties, classified by income type.
- Determine the rate per stream: Circular 103 for outbound payments from Vietnam; Chinese tax law for China-linked flows.
- Put tax clauses in contracts (Vietnamese edition; English URL wiring pending at publish): price inclusive/exclusive of tax, who bears policy changes, documentation duties.
- Start treaty procedures early: tax-residence certificates take time — apply before the first payment.
- Keep withholding records: withholding and payment certificates are the basis for the recipient's foreign tax credit claims at home.
Cross-border digital services risk: SaaS fees, digital advertising and software licence payments to offshore providers with no Vietnam presence can still fall within FCT — and the recurring fight is classification: "services" (5% VAT / 5% CIT) versus "royalties" (10% CIT). The rate gap between the two classifications is wide enough to turn a profitable contract into a loss after finalisation. Digital-economy tax policy has been moving fast since 2025; before any high-value contract, seek specialist advice or a written ruling from the tax authority instead of self-classifying.
6. Frequently asked questions
Q: Who is subject to Vietnam's foreign contractor tax?
A: Foreign organisations and individuals doing business in Vietnam or earning Vietnam-sourced income under contracts with Vietnamese parties — except exclusions under current tax law (previously in Circular 103/2014/TT-BTC, repealed from 1/7/2026).
Q: What is the FCT rate for ordinary services?
A: From 1/7/2026, Circular 103/2014/TT-BTC was repealed; foreign contractor tax filing now follows Article 30 of Circular 89/2026/TT-BTC. Ordinary services bear 5% VAT and 5% CIT on deemed revenue; e.g. royalties 10% CIT, loan interest 5% CIT — per current VAT and CIT law (CIT rates under Article 12 of Decree 320/2025/ND-CP). Each payment must be correctly classified.
Q: What is China's withholding tax rate?
A: Chinese law sets a 20% statutory rate on non-resident enterprises' income, but in practice 10% is commonly applied under implementing rules to many income types (dividends, interest, royalties). The applicable rate depends on income type and the tax treaty.
Q: What does the Vietnam-China DTA do?
A: The treaty allocates taxing rights and typically lowers withholding rates on dividends, interest and royalties versus domestic law. Enterprises must complete treaty notification/relief procedures in the payer's country to benefit — it is not automatic.
Q: Is there a penalty for not withholding on payments to foreign contractors?
A: Yes. The Vietnamese payer must withhold, declare and pay FCT on behalf. Failure may trigger reassessment, late-payment penalties and tax administrative sanctions. Unwithheld tax is also commonly non-deductible for CIT.
