Vietnam Tax Residency for Foreigners (the 183-Day Rule)

Vietnamese personal income tax (PIT) treats foreigners differently depending on whether they become tax-resident in Vietnam. The dividing line is the 183-day test. Cross it in a calendar year (or in a rolling 12-month period from your first day in country) and you become liable for Vietnamese PIT on your worldwide income — not just income earned in Vietnam.

This page is general information, not tax advice. Tax residency and treaty positions are fact-specific. Consult a qualified Vietnamese tax professional before relying on any plan that depends on your status.

The 183-day rule

You are a Vietnamese tax resident if either:

• You are present in Vietnam for 183 days or more in a calendar year (1 January–31 December), OR
• You are present in Vietnam for 183 days or more in any 12 consecutive months starting from your first day of presence.

Days are counted on a same-day basis — entry and exit days each count as a full day. The test is mechanical and well-understood by Immigration and the tax authority.

You are also a tax resident if you have a permanent residence in Vietnam (e.g., a registered home address) or rent a residence in Vietnam for 183+ days, even if you spend fewer than 183 days in country.

What changes when you become resident

Progressive PIT rates for residents (employment income)

The brackets are applied to taxable income — gross less the basic deduction (VND 11M/month, ~$440), dependent deductions (VND 4.4M/dependent), and mandatory contributions.

Worldwide income for residents

The complication for remote workers: as a resident you are technically liable for PIT on income from foreign employers and foreign clients paid into foreign bank accounts.

Vietnam mitigates this through double-taxation treaties. If you pay tax on the same income in another treaty country, you typically get a credit against Vietnamese PIT.

Treaty status (as of 2026-05-17)

The unratified US treaty is the most significant gap. US citizens working from Vietnam typically face the awkward situation of being liable for US federal tax (worldwide for citizens) AND Vietnamese PIT if resident, with no formal treaty relief. The Foreign Earned Income Exclusion (FEIE) and Foreign Tax Credit (FTC) on the US side can mitigate but require careful planning.

Practical realities by visa class

Remote workers cycling e-visas

There is no confirmed long-stay Vietnamese visa for general remote workers — read the reality check. What this means for tax: physical presence, not visa class, is what triggers Vietnamese tax residency. If you spend 183+ days in Vietnam — on e-visa cycles or anything else — in principle you owe Vietnamese PIT on worldwide income. Enforcement against pure foreign-source remote workers has historically been light, but the General Department of TaxationTổng cục Thuế (Tong cuc Thue)tong kook tweGeneral Department of Taxation. Vietnamese tax authority; publishes PIT, CIT, VAT and tax-residency rules and forms. has signalled increasing focus on this area. Don't plan around lax enforcement.

Work permit holders

Your employment is Vietnamese-source and PIT is withheld by your employer. Worldwide income reporting is the foreign-income piece — if you maintain rental income, dividends, or freelance work outside Vietnam, you're expected to declare and pay (with treaty credit).

Investor visa holders

Investment income from your Vietnamese company is Vietnamese-source. Other worldwide income is treated as above.

Tourists and visa-runners

If you're staying below 183 days per year, you're a non-resident — no Vietnamese PIT obligation on foreign-source income.

Other Vietnamese tax considerations for foreigners

• Social insurance: Mandatory for work-permit holders since 2018. Both employer and employee contribute. The contribution rate is ~8% employee + ~17.5% employer of qualifying salary.
• VAT: 10% standard rate on most goods and services. You pay it as a consumer; companies recover it.
• Property tax: Limited — Vietnam has no general annual property tax. Transaction taxes (registration fee, PIT on rental income for landlords) apply.
• Inheritance / estate tax: None at this writing. Gift tax exists at 10% for unrelated parties.
• Crypto: Not currently subject to a specific regulatory tax regime; PIT applies to gains as "other income" in principle. Heavily watched for upcoming legislation.

Filing mechanics

For employment income via a Vietnamese employer:

• Monthly PIT withheld by employer
• Annual finalisation due by 31 March of the following year (or 30 April if using a tax agent)

For foreign income (residents):

• Self-assessed quarterly provisional payments
• Annual finalisation as above

What to do

1. Track your days carefully. A spreadsheet of entry/exit dates is sufficient.
2. Don't accidentally cross the line — if you're hovering near 183 days and don't want to be resident, plan a longer trip out of Vietnam.
3. Get advice before your first full year as resident. Vietnamese PIT for residents with foreign income is genuinely complex, especially if the home country is the US or another non-treaty country.
4. Treaty filings require evidence — pay slips, foreign tax returns, certificates of residency from the other country. Build the file before you need it.

Who to ask

There's a small but growing community of English-speaking tax advisors in HCMC and Hanoi who handle expat tax cases. Standard fees for an individual annual finalisation: $300–800 plus government fees. Search for "expat tax Vietnam" or ask in expat communities. Big-4 firms (Deloitte, PwC, EY, KPMG) all have Vietnam tax practices and serve high-net-worth individuals as well as companies.

What this does NOT let you do

Becoming a Vietnamese tax resident is a legal status triggered by physical presence — it is not a visa category, and it grants no additional immigration permissions or entitlements. Specifically:

• Extend or replace your visa — tax residency has no bearing on your immigration status. You still need a valid visa or residence permit; overstaying is an offence regardless of tax obligations.
• Work legally for a Vietnamese employer — that requires a work permit and the correct visa category (e.g., LD visa). Tax residency alone does not authorise local employment.
• Offset foreign-source income without a treaty — if your home country has no double-taxation treaty with Vietnam (notably the US, where the treaty is unratified), you may need to verify with a qualified tax advisor how to avoid double taxation; there is no automatic relief.
• Ignore Vietnamese PIT on foreign income — once you cross the 183-day threshold, worldwide income is in scope in principle. You may need to verify your specific position with a Vietnamese tax professional rather than assuming enforcement won't apply.
• Access any "digital nomad" or "retirement" visa pathway — Vietnam has no confirmed general visa for either category. Anyone cycling on e-visas and crossing the 183-day line may need to verify their full tax exposure with a specialist.

Refer to the digital nomad reality check or the retirement reality check where remote work or retirement comes up — Vietnam has no confirmed general route for either.
