Question 1

How is an expatriate's tax residency in Vietnam determined?

Accepted Answer

An individual is generally treated as a Vietnam tax resident if present in Vietnam for 183 days or more in a calendar year, or 183 days or more within any 12 consecutive months counted from their first date of arrival — or if they meet the statutory permanent/regular residence test. A tax resident is generally taxed on income arising both inside and outside Vietnam; a non-resident is taxed only on income arising in Vietnam. For someone arriving partway through a year, the 12-consecutive-month test is often the one that actually applies, so entry and exit dates should be tracked continuously rather than assessed only at year-end. (Law on Personal Income Tax No. 109/2025/QH15, effective 1 July 2026, as amended by Law No. 09/2026/QH16.)

Question 2

What Personal Income Tax rates apply to foreign employees in Vietnam?

Accepted Answer

Nationality doesn't determine a foreign employee's PIT rate — tax-residency status does. A resident's employment income is taxed on a progressive schedule: 5% up to VND 10 million/month, 10% from VND 10–30 million, 20% from VND 30–60 million, 30% from VND 60–100 million, and 35% above VND 100 million, after a personal deduction of VND 15.5 million/month plus VND 6.2 million/month per qualifying dependent. A non-resident's Vietnam-sourced employment income is instead taxed at a flat 20%. A resident isn't automatically taxed more overall — the deductions applied before the progressive rates can offset that. (Law No. 109/2025/QH15, effective 1 July 2026, as amended by Law No. 09/2026/QH16.)

Question 3

What happens if an expatriate's tax residency status changes partway through the year?

Accepted Answer

Residency isn't simply "non-resident before day 183, resident from day 183" — Vietnam also applies a 12-consecutive-month test counted from the individual's first arrival date, so a status set early in an assignment can still be provisional. If later travel records show the residency conditions are met, a reassessment may be needed covering the applicable tax period, the PIT already withheld, available deductions, and whether the final position leaves additional tax due or an amount to reclaim. Tax already withheld during the provisional period isn't lost — it carries into that reassessment rather than being recalculated automatically month by month. (Law No. 109/2025/QH15, as amended by Law No. 09/2026/QH16.)

Question 4

Are foreign employees required to participate in Vietnam's compulsory Social Insurance?

Accepted Answer

Generally yes, if the statutory conditions are met — a foreign employee working under a qualifying employment arrangement with a Vietnam-based employer, most commonly a fixed-term contract of at least 12 months, is generally subject to compulsory Social Insurance. Three exclusions apply: qualifying intra-company transferees, employees who had already reached statutory retirement age when the contract was signed, and cases where an applicable international treaty provides otherwise. Holding a work permit doesn't by itself decide the answer — the employment contract and its duration are what actually determine Social Insurance liability. (Social Insurance Law No. 41/2024/QH15, effective 1 July 2025; Decree No. 219/2025/ND-CP on foreign workers, effective 7 August 2025.)

Question 5

How much Social Insurance and Health Insurance must a foreign employee pay?

Accepted Answer

These are separate contributions and shouldn't be added into one combined rate. For Social Insurance, a covered foreign employee contributes 8% of the contribution base and the employer contributes 17%, for a combined 25%. Health Insurance is a separate contribution: the employee pays 1.5% and the employer 3%, for a combined 4.5%. Foreign employees are generally outside the coverage of Vietnam's unemployment insurance regime, so no contribution applies there. (Social Insurance Law No. 41/2024/QH15, effective 1 July 2025; Decree No. 188/2025/ND-CP on Health Insurance; Employment Law No. 74/2025/QH15, effective 1 January 2026.)

Question 6

Do foreigners working remotely for an overseas company while staying in Vietnam have to pay Vietnamese PIT?

Accepted Answer

Potentially yes — the answer turns on tax-residency status, not on where the employer or bank account is located. A Vietnam tax resident is generally taxed on worldwide income, so a foreign employer paying into a foreign bank account doesn't by itself put that income outside Vietnam's tax scope. For a non-resident, the question instead is whether the income is considered to arise in Vietnam. This has to be assessed against the individual's actual circumstances, not assumed from physical location alone. (Law No. 109/2025/QH15, as amended by Law No. 09/2026/QH16.)

Question 7

If my salary is paid overseas, do I still have to declare it in Vietnam?

Accepted Answer

Potentially yes, particularly for a Vietnam tax resident — residents are generally taxed on income arising both inside and outside Vietnam, so overseas salary, bonuses, and certain allowances can all need to be reviewed. Being paid by an overseas company, in foreign currency, or into an overseas account doesn't by itself decide whether the income is taxable in Vietnam. For a non-resident, the question instead is whether the income falls within Vietnam's taxable scope. (Law No. 109/2025/QH15, effective 1 July 2026, as amended by Law No. 09/2026/QH16.)

Question 8

Can an expatriate be taxed in both Vietnam and their home country?

Accepted Answer

Yes, potentially — both countries' domestic tax rules can apply to the same income. That doesn't automatically mean the income ends up taxed twice: where Vietnam has a Double Taxation Agreement with the other country, the treaty can allocate taxing rights, limit one country's claim, or provide relief such as a foreign tax credit. The right analysis works through tax residency, income source, where the employment is actually exercised, each country's domestic rules, and then the specific treaty that applies — nationality alone doesn't decide it, and the outcome needs to be checked treaty by treaty, not assumed to be the same for every country.

Question 9

Does an expatriate need to complete PIT finalization before leaving Vietnam?

Accepted Answer

A tax review should be done before an assignment ends or the individual permanently leaves Vietnam — whether formal finalization is required, and how, depends on the person's circumstances. The review needs to establish final tax-residency status, the applicable tax period, total taxable income (including relevant overseas employment income), tax already withheld or paid, applicable deductions, and the resulting balance due or refundable. This matters most where residency status was still provisional for part of the assignment, since that's exactly the situation that needs reconciling before departure. (Law No. 109/2025/QH15, effective 1 July 2026, as amended by Law No. 09/2026/QH16.)

Question 10

When a representative office or company closes in Vietnam, must employee PIT and Social Insurance obligations be settled?

Accepted Answer

Yes — outstanding employee-related tax and Social Insurance obligations need to be reviewed and settled as part of closing, covering payroll, taxable income, PIT withheld/declared/paid, required finalization, Social Insurance contribution history, and any outstanding amounts before employees can be deregistered. A representative office and an incorporated Vietnamese company follow different termination procedures, though — a representative office closes under the separate RO/branch framework (Decree No. 07/2016/ND-CP), not the same dissolution process as a company, so the entity type needs to be confirmed first.
