How Foreign IT Freelancers Can Legally Work and Invoice Clients from Vietnam

You are an IT freelancer living in Vietnam. You have clients in the US, Europe, or Singapore, and your work is entirely online. You invoice from your home country, receive payments into a foreign bank account, and assume that because your clients are overseas, Vietnamese tax rules do not apply to you. Then you read about the 2025 Tax Administration Law, the new personal income tax rules taking effect in July 2026, and the mandatory e-invoicing requirements for individuals earning income in Vietnam, and you realize the gray zone you have been operating in is closing fast. The rules have changed dramatically in 2026, and most online guides are already out of date. This guide breaks down the legal framework, the tax registration requirements, the invoicing rules, and the common mistakes that foreign IT freelancers make when working from Vietnam.

What Legal Framework Governs Foreign Freelancers in Vietnam?

The regulatory landscape for foreign freelancers in Vietnam was reshaped by several laws and decrees that took effect in 2025 and 2026.

The first is the Law on Tax Administration No. 108/2025/QH15, passed on December 10, 2025, and effective from July 1, 2026, with certain provisions on e-invoicing for business households and individuals taking effect earlier on January 1, 2026. This law explicitly includes foreign individuals and organizations conducting business in Vietnam or having income in Vietnam as taxpayers, and also covers foreign individuals and organizations undertaking business on e-commerce platforms and other digital platforms.

The second is the Law on Personal Income Tax No. 109/2025/QH15, effective from July 1, 2026. This law restructures the personal income tax regime, clarifies the tax treatment of foreign assignments, and establishes new rules for business income earned by resident and non-resident individuals.

Implementing these laws are Decree No. 252/2026/ND-CP dated June 30, 2026, which provides detailed guidance on tax registration under the new Tax Administration Law, and Circular No. 90/2026/TT-BTC issued by the Ministry of Finance on July 13, 2026, which specifies the procedures for tax registration, including for foreign individuals and non-resident individuals doing business on digital platforms.

Pro Tip: The distinction between "resident" and "non-resident" is the single most important factor determining your tax exposure. A foreign individual is considered a tax resident if present in Vietnam for 183 days or more in a calendar year or in 12 consecutive months from the first day of arrival. Residents are taxed on worldwide income at progressive rates. Non-residents are taxed only on Vietnam-sourced income.

Do You Need a Work Permit as a Foreign IT Freelancer in Vietnam?

Whether you need a work permit depends on the nature of your work and your residency status. Vietnam does not offer a specific digital nomad visa or a visa for self-employed individuals. The most common visa pathway for remote workers is a business visa or an e-visa, both of which are short-term solutions that do not resolve the underlying work authorization question.

Under Article 154 of the Labor Code 2019 and Article 7 of Decree No. 219/2025/ND-CP, foreign workers may be exempt from a work permit in specific circumstances, including short-term assignments of less than 90 days in a calendar year, or performing work exclusively online without entering Vietnam. However, if you are physically present in Vietnam and performing work, even remotely for foreign clients, you may fall within the scope of work authorization rules, and the exemption confirmation procedure must still be completed.

If you register a 100% foreign-owned LLC and appoint yourself as the legal representative, you can apply for a work permit exemption and obtain a Temporary Residence Card tied to the company. This is a common structure for freelancers who want a long-term legal basis for their stay and work in Vietnam.

Warning: Working in Vietnam without the appropriate visa or work authorization, even if your clients are overseas and your income is paid into a foreign account, is a violation of Vietnamese law. Enforcement of immigration and labor rules has increased, and the consequences can include fines, deportation, and future entry bans.

Tax Registration Requirements for Foreign Freelancers

Under Circular No. 90/2026/TT-BTC, non-resident individuals doing business on e-commerce platforms that do not have online ordering and payment functions are required to carry out tax registration directly with tax authorities. Foreign individuals and organizations conducting business in Vietnam or having income in Vietnam are included as taxpayers under the Law on Tax Administration 2025.

For foreign contractors involved in contracts with Vietnamese parties, a separate 10-digit tax code can be issued for each contract if the foreign contractor wishes to declare and pay taxes separately. Non-resident individuals doing business on digital platforms without ordering and payment functions must register directly with the tax authority.

Tax registration deadlines under Decree 252/2026/ND-CP must be observed. Taxpayers subject to direct registration with tax authorities may submit dossiers via the National Public Service Portal, the National Identification Application, or the Tax Administration Information System.

Required Documents for Tax Registration

Tax registration application form — the form prescribed by the tax authority for individuals registering for a tax identification number.
Valid passport — a copy, with the original presented for verification.
Valid visa or Temporary Residence Card — a copy, for foreign individuals.
Contract or documentation of income source — copies of contracts with Vietnamese clients or platforms, if applicable.
Proof of residence in Vietnam — for resident individuals, documentation of the 183-day presence or permanent residence.

Pro Tip: A 10-digit tax identification number is issued to independent organizations and foreign individuals who do not have a personal identification number. This means you can register for tax and receive a tax code even without a Vietnamese citizen ID card. The process is designed to accommodate foreign individuals.

How Are Foreign Freelancers Taxed in Vietnam?

The tax treatment of your freelance income depends primarily on your tax residency status and whether your income is considered Vietnam-sourced.

For tax residents: Vietnamese residents pay personal income tax on worldwide income at progressive rates from 5% to 35%. For business income, rates range from 1% to 5% depending on the activity type. From the 2026 tax year, a resident taxpayer may claim a personal deduction of VND 15.5 million per month (VND 186 million per year).

For non-residents: Non-resident individuals are taxed only on Vietnam-sourced income. Employment income earned by a non-resident is generally taxed at a flat 20% rate. For business income, non-residents are subject to tax on the portion of income earned in Vietnam.

Foreign Contractor Tax (FCT): Foreign individuals conducting business activities in Vietnam are subject to foreign contractor tax, which combines value-added tax and personal income tax. FCT applies to foreign organizations and individuals who do not have a commercial presence in Vietnam but have income generated from providing services or goods in Vietnam through contractor or subcontracting contracts. If you are contracting with Vietnamese clients, the Vietnamese party is responsible for withholding and remitting FCT on your behalf.

Tax exemption threshold: From January 1, 2026, the annual revenue threshold for exemption from VAT and personal income tax for business households and individuals has been raised from VND 100 million to VND 1 billion per year. If your annual revenue from Vietnamese-sourced business activities is at or below VND 1 billion, you are not required to pay VAT or personal income tax on that business income. This threshold does not apply to employment income or to all categories of personal income.

Important Distinction: The VND 1 billion exemption threshold applies to business income from registered business households and individual businesses. It does not apply to employment income, investment income, or other categories of personal income. If your freelance work is characterized as business income and you are properly registered, the threshold applies. If it is characterized as employment or contractor income, different rules and rates apply.

E-Invoicing Requirements for Foreign Freelancers

One of the most significant changes in 2026 is the expansion of mandatory e-invoicing to foreign individuals and organizations operating on e-commerce and digital platforms. From July 2026, the e-invoicing regime explicitly includes foreign organizations and individuals operating on e-commerce and digital platforms. These taxpayers have been permitted to voluntarily register for Vietnamese e-invoices since June 1, 2025.

Business individuals who do not register their business households are still subject to the use of e-invoices. The tax authority has upgraded its systems to allow business individuals without a business household registration certificate to register for e-invoice use.

For foreign customers, invoice information requires the passport number or entry/exit document and nationality in place of the Vietnamese personal identification number.

E-Invoice Registration Process

Register for a tax code with the tax authority if you have not already done so.
Register for e-invoice use through the tax authority's electronic portal or the Tax Administration Information System.
Obtain a digital signature for signing e-invoices, unless you qualify for an exemption.
Use the e-invoice template prescribed by the tax authority for each transaction.
Store and retain e-invoice records in accordance with the tax authority's data management requirements.

Pro Tip: If you are a foreign individual who has not yet registered for a VNeID level-2 electronic identification account, you may temporarily be exempt from certain e-invoice registration requirements. However, this exemption is temporary, and you should plan to complete the registration process as soon as possible.

Common Mistakes Foreign IT Freelancers Make

Assuming foreign-sourced income is not taxable. If you are a tax resident in Vietnam (present for 183 days or more), you are taxed on worldwide income, regardless of where your clients are located or where payment is received. Non-residents are taxed only on Vietnam-sourced income, but determining whether your income is Vietnam-sourced depends on the nature of the work and the location where it is performed.
Not registering for a tax code. Foreign individuals and non-resident individuals doing business on digital platforms are required to register for tax directly with the tax authority. Operating without a tax code creates compliance exposure and prevents you from issuing valid invoices.
Ignoring e-invoicing requirements. From July 2026, foreign individuals operating on digital platforms are included in the mandatory e-invoicing scope. Failure to comply can result in penalties and invalidates the invoices you issue to clients.
Using a tourist visa for long-term work. Vietnam does not offer a digital nomad visa or a visa for self-employed individuals. Working on a tourist e-visa is a violation of immigration rules, even if your clients are overseas. Consider registering a company or obtaining the appropriate work authorization.
Failing to distinguish between resident and non-resident status. The 183-day threshold determines whether you are taxed on worldwide income or only Vietnam-sourced income. Miscalculating your residency status can lead to significant tax underpayment and penalties.
Not registering as a business household or individual business. Foreign individuals cannot register a household business in Vietnam, as the law requires the owner to be a Vietnamese citizen. However, foreign individuals can register as independent contractors or establish a sole proprietorship or limited liability company. The appropriate structure depends on your specific situation.
Assuming FCT does not apply. If you contract with Vietnamese clients, foreign contractor tax applies and the Vietnamese party is responsible for withholding and remitting it on your behalf. Even if your contract is structured through an overseas entity, the substance of the arrangement may trigger FCT obligations.

Disclaimer: Administrative regulations are subject to official policy updates. Always cross-check with the official immigration/government authority before final submission.
