Vietnam tax for remote workers: the 183-day rule, the lease test and what you owe

Article 2 of Law 109/2025/QH15 defines a resident with two independent tests. Meeting either one is enough, and the second is the one that catches remote workers who think visa runs keep them safe.

Test one: presence. You are resident if you are present in Vietnam for 183 days or more, either in a calendar year or in any 12 consecutive months counted from your first day of arrival. The days do not have to be consecutive, so a weekend visa run to Bangkok resets nothing; it only takes the days you spend abroad off the total.

Test two: a place to live. You are also resident if you have a habitual residence in Vietnam: a registered place of residence, or a rented house. PwC's summary (reviewed 23 September 2026) describes the rented home as one "with a definite lease term", and Acclime's guide (updated 14 August 2026) counts a temporary or permanent residence card and a lease of 183 days or more. The test looks at the contract, not at whether you sleep in the flat. Sign a six month lease in An Thuong in March, fly out for the summer, and the lease can still make you resident for the year.

Why this matters more in Vietnam than elsewhere. Landlords in Da Nang often quote a better monthly rate for six or twelve months, and a contract with a break clause after three months still has a stated term of six or twelve months. Month-to-month arrangements and serviced apartments stay outside the housing test, at a higher price. The Da Nang housing guide covers what the contracts look like, and our Vietnam country page puts tax next to visas and costs.

What residency changes. A resident is taxed on worldwide employment income, wherever it is paid. A non-resident is taxed only on income arising in Vietnam, which includes pay for work done in Vietnam. The short answer on leases lives at does renting for six months make me a Vietnamese tax resident.

The most common misunderstanding is that the count resets on 1 January. It does not, because the second window starts on the day you first arrive.

The straddling stay. Land on 1 September 2026 and stay until 30 June 2027, and you spend 122 days in Vietnam in 2026 and 181 in 2027. You fail the calendar test in both years and still become resident, because day 183 from first arrival falls around 2 March 2027. Our post on the four things people get wrong about Vietnam's 183 day rule sets out that case in a table, with the law's wording.

What counts as a day. Your entry and exit stamps and your e-visa PDFs are the evidence. How the tax office counts the day you arrive and the day you leave is a detail to confirm with an adviser; the safe plan is to count every day you are in the country for any part of the day, and to keep your own log from your first entry.

A worked calendar. Suppose you plan two 90-day e-visa stays in one year with a month in Thailand in between. From 15 January to 14 April you spend 90 days in Vietnam. From 15 April to 14 May you are out of the country. From 15 May to 12 August you spend another 90 days. That is 180 days in the calendar year; add a long weekend in Hanoi in December and you are at 183. The margin is that thin, so anyone planning two full e-visa stays in one year should count precisely. The leave-by checker is a starting point for the dates.

Visa type does not matter. An e-visa holder and a residence card holder are judged on the same presence test; the card also satisfies the housing test on its own. A visa run keeps your stay legal and does nothing to the tax count.

The residency label decides two things: which income is in scope, and which rate applies.

Non-residents. Taxed only on income arising in Vietnam, and on salary at a flat 20 percent with no deductions. Article 21 of Law 109/2025/QH15 applies that rate to a non-resident's salary income "regardless of income payers", and Vietnam Briefing's income tax guide describes the scope as Vietnam-sourced employment income. The widely repeated line "under 183 days and paid abroad, you owe nothing" therefore holds only if the work itself is not done in Vietnam. A remote employee who works from a Da Nang coworking space for a Berlin employer is, on the letter of the law, doing the work in Vietnam. Whether a treaty with your home country exempts that pay for a short stay is a question for the treaty section below and for an adviser.

Residents. Taxed on worldwide employment income regardless of where it is paid or earned, at the progressive rates in the next section, after deductions. A resident with a German employer owes Vietnamese tax on the German salary in principle, whether or not a single dong lands in a Vietnamese bank. Investment income, capital gains, rental income and prizes have their own rates for both groups; this guide sticks to employment and freelance income because that is what remote workers earn.

The difference in numbers. Take a salary of VND 104 million a month (about USD 4,000). As a resident with no dependants, the tax is about VND 17 million a month, as the worked example below shows. As a non-resident, 20 percent of the pay for work done in Vietnam would be VND 20.8 million for a full month. The flat rate with no deduction is not a discount.

Who is most visible. Employees whose Vietnamese subsidiary hosts them or recharges their cost, consultants with a Vietnamese client, and anyone paid into a Vietnamese bank account. A Vietnamese payer is expected to withhold, and a bank asked to send money abroad asks for tax documents. For a remote worker paid entirely from abroad, the enforcement section below describes the practice.

Law No. 109/2025/QH15 of 10 December 2025 took effect on 1 July 2026, and the Ministry of Finance's National Institute for Finance (27 January 2026) confirms that its rules on residents' salary and business income apply from the 2026 tax year. It cut the number of salary brackets from seven to five and kept the top rate at 35 percent.

Deductions. Article 10 sets VND 15.5 million per month for yourself (up from VND 11 million) and VND 6.2 million per month per registered dependant (up from VND 4.4 million). Compulsory social, health and unemployment insurance contributions are also deductible when you pay them, which mainly concerns people on a Vietnamese payroll. Vietnam Briefing (30 June 2026) puts the monthly salary below which a resident owes nothing at about VND 17 million with no dependants, VND 24 million with one and VND 31 million with two.

Worked example: USD 4,000 a month, no dependants, paid by a foreign employer, resident. At an illustrative rate of VND 26,000 to the dollar (check today's rate with Currency Check), the salary is VND 104 million a month. The law sets the bands on annual income; the monthly figures below are the same bands divided by twelve.

1. Gross monthly income: VND 104,000,000.
2. Less the personal deduction of VND 15,500,000: taxable income of VND 88,500,000.
3. First VND 10 million at 5 percent: VND 500,000.
4. Next VND 20 million (10 to 30 million) at 10 percent: VND 2,000,000.
5. Next VND 30 million (30 to 60 million) at 20 percent: VND 6,000,000.
6. Remaining VND 28.5 million (60 to 88.5 million) at 30 percent: VND 8,550,000.
7. Monthly tax: VND 17,050,000, about USD 656. Over a year: VND 204.6 million, about USD 7,870.

The effective rate on gross pay is about 16.4 percent. With one dependant, taxable income falls to VND 82.3 million and the monthly tax to about VND 15.2 million (USD 584). No foreign tax credit is applied here; if your home country also taxes the salary and a treaty applies, the credit in the next section reduces the Vietnamese figure.

What the example leaves out. Insurance contributions (none, since the employer is abroad), benefits in kind such as employer-paid housing, and the annual finalization. The liability is assessed on the year, so treat the monthly figure as an illustration. The short version is in how much income tax do you pay in Vietnam as a tax resident.

Becoming a Vietnamese tax resident rarely means paying tax twice in full, because Vietnam has double tax agreements with more than 80 countries and territories, according to Acclime's treaty guide. What it does mean is paperwork on a deadline.

How relief works. A treaty either exempts certain income from Vietnamese tax or lets you credit the tax paid in the other country against the Vietnamese bill, up to the Vietnamese amount. Which one applies depends on the treaty's article on employment income and on where you are resident under the treaty's tie-breaker rules, so read your own country's treaty rather than a summary of someone else's.

The 15-day rule. Vietnam does not apply treaty relief automatically. Acclime states that the notification must reach the Vietnamese tax authority 15 days before the tax payment deadline, with a certificate of tax residence from the other country and the supporting contracts. Miss it and you pay the domestic tax first; late applications are accepted within three years of the payment due date, so money can be recovered, slowly.

Circular 95/2026/TT-BTC: substance over form. W&A Consulting (7 September 2026) reports that from 1 July 2026 the authority assesses functions, assets, personnel, control, risks and commercial purpose behind a claim, and that a residence certificate is "necessary but often no longer sufficient on its own" for higher-risk transactions. The rule was written with companies in mind, but the same lens fits an individual who claims residence in a country they no longer live in. If your certificate says Portugal and you left Portugal two years ago, expect questions.

The US gap. Vietnam does not appear on the IRS list of United States income tax treaties. A US citizen resident in Vietnam relies on US domestic rules instead: the foreign earned income exclusion, which needs either bona fide residence abroad or 330 full days abroad in 12 consecutive months and has an annual cap set by the IRS, and the foreign tax credit for Vietnamese tax paid. Both are claimed on the US return; Vietnam gives nothing on its side. The short version, with the current cap, is is there a US Vietnam tax treaty.

What to bring to a treaty claim. A residence certificate for the same year, the employment contract, payslips showing tax withheld abroad, and a log of days in each country. Treaty positions are where a paid adviser saves more than they cost, and the last section lists the questions to ask one.

If you have concluded you are resident, the mechanics are mostly annual. The tax year is the calendar year.

Step one: a personal tax code. Anyone who declares income in Vietnam needs a tax identification number. On a Vietnamese payroll, the employer registers you. Otherwise you register with the tax office that covers the place you live, with your passport, your visa or residence card and proof of address, which is where your landlord's temporary residence declaration becomes useful. The setting-up guide covers that declaration and the order in which to do the admin.

Step two: pay during the year. Employers withhold monthly. A resident with only foreign income has no Vietnamese withholding, so the declaration and payment schedule is something to set up with an adviser on the tax authority's electronic portal.

Step three: annual finalization. According to Acclime and the Vietnam Briefing finalization Q&A, the deadline is 31 March when an employer finalizes for employees who authorise it, and 30 April when you file yourself. When the date falls on a weekend or public holiday it moves to the next working day: the 2024 finalization was due on 2 May 2025. The finalization is where you claim deductions, dependants and foreign tax credits, and where any refund or shortfall is calculated.

Leaving Vietnam for good. Vietnam Briefing states that foreign employees leaving Vietnam must finalize within 45 days of departure. This is the step people forget, and an unfinalized year can resurface if you later come back on a sponsored visa.

Pitfalls in practice. Registering a tax code because a bank asked for one puts you in the system, and a code with no filings invites a query. Dependant deductions require registering the dependant with documents; they are not automatic. Foreign tax credits are given only for tax actually paid abroad and documented, so a home return showing zero tax gives no credit. Late filing and late payment carry penalties and interest, and an adviser will quote the current figures.

None of this needs a lawyer for a single-salary resident, but it does need the residency question answered before the deadlines arrive. The 183 day rule explainer and the visa guide explain the stays that lead here.

Most of this guide assumes a salary. Many remote workers in Vietnam are freelancers, agency owners or creators paid through platforms, and some hold crypto. The new law touches each group.

Freelance income for residents. The principle is the same as for salary: a resident is taxable on income from anywhere. Freelance income can be treated as salary-like income (a service contract with one client that looks like a job) or as business income of an individual, and the classification changes the rate and the deductions. Vietnam Briefing's summary of the new law notes that it brings platform and e-commerce income more clearly into scope. The correct treatment of a foreign freelancer depends on facts an adviser needs to see: the number of clients, the contract form, where the clients are, and whether you invoice through a company abroad.

Non-resident freelancers. The sources we rely on cover salary income, and they do not settle how the tax authority treats a non-resident invoicing foreign clients from a laptop in Hoi An. That is a question for a Vietnamese adviser, not a general guide. What is clear is that a Vietnamese client changes the picture: the payer is expected to withhold, and working for a local client raises the work permit question covered in the visa guide.

Digital assets. Article 19 of the law taxes income from transfers of digital assets at 0.1 percent of the transfer price, and Vietnam Briefing lists gold bars, carbon credits and auctioned licence plates alongside them. How exchanges and wallets will report is still being set out in guidance, so a resident who trades should assume the rate applies and keep records.

What did not loosen. The residency tests, the worldwide scope for residents and the 20 percent flat rate for non-residents. The law changed how much a resident pays (five brackets, higher deductions), not whether they pay.

A note on companies abroad. Invoicing through a company in Estonia or the United Kingdom does not remove the personal question. If you are resident in Vietnam and draw a salary or dividends from that company, those are personal income, and if you run the company from Vietnam, the substance lens of Circular 95/2026 is the one the authority would use to ask where it is really managed. That is corporate tax territory, outside this guide, but it belongs on your adviser's list.

We are not going to pretend that every remote worker who crosses 183 days files a Vietnamese return, and it would be misleading to describe the law without the practice. The practice is also changing, and the moments when it catches up with people are predictable.

Where the authority can see you. Immigration records your days. The tax authority sees what employers, banks and platforms in Vietnam report to it. For a foreigner with no Vietnamese payer, nothing in the sources we read links a passport full of stamps to a tax assessment automatically. That is why a remote worker paid entirely from abroad is hard for the authority to see today, and why the legal position above still applies to them.

Where you become visible. Four events put you in the system:

1. A temporary residence card. Holding one satisfies the housing test on its own, and card holders are the first group any data matching would cover.
2. A Vietnamese bank account receiving salary. The account shows income arriving monthly, and under Circular 27/2025, in force since 1 November 2025, banks report international transfers of USD 1,000 or more to the State Bank.
3. Sending money out. Most banks require a branch visit for outbound international transfers and ask for employment, payroll, tax and immigration documents. A resident with no tax code and no filings finds this conversation difficult.
4. A work permit or a Vietnamese company. Both create a Vietnamese payer or entity, and both come with withholding and reporting.

The honest framing. If you cycle e-visas, stay under 183 days in both windows, rent month to month and are paid abroad, your exposure is low but not zero, because the 20 percent rule covers work done here. If you sign a year's lease, open a local account and have your salary paid into it, you have met the housing test and created a paper trail. Plan for the second case before you are in it.

Questions to bring to a Vietnamese tax adviser. An hour is usually enough for these six:

1. Given my entry and exit dates and my lease term, am I resident this year under either test, and from which date does my 12-month window run?
2. Is my pay for work done in Vietnam taxable here while I am non-resident, and does my home country's treaty exempt it for a short stay?
3. What does my treaty's employment article say for my case, and what documents and dates does the 15-day notification need?
4. Should I register a tax code now, or only once I have a Vietnamese payer or a residence card?
5. How should my freelance or platform income be classified, and what records should I keep for digital asset transfers?
6. If I leave, what does the 45-day finalization involve and what do you charge to file it?

The expert block below connects you with a tax professional who works with foreign residents; it is there because this is the part of the guide where general information stops being enough.
