Income Tax for Expats in Vietnam: A 2026 Guide

Income tax for expats in Vietnam is easy to ignore — until a finance team, a year-end finalisation form, or a tax code you suddenly need forces the issue. The honest position: most foreigners working in HCMC are taxable here, the rates changed in 2026, and “my company handles everything” isn’t always true. This guide explains who counts as a Vietnamese tax resident, what income Vietnam can tax, the current rates, and the traps that catch newcomers. Tax is personal, the law is brand new, so treat this as a clear orientation — not a substitute for advice on your own situation.

The 2026 law change you can’t ignore

Vietnam enacted a new Personal Income Tax Law — Law 109/2025/QH15 — which takes effect on 1 July 2026, with the resident salary-and-wage rules applying from the 2026 tax year. The headline changes for an ordinary foreign employee: a five-bracket progressive table (down from seven), and a much higher personal deduction.

Are you a Vietnam tax resident?

Everything starts here, because residency decides how much of your income Vietnam can tax. You are a Vietnamese tax resident if you meet either of two independent tests:

• The day count. You’re present in Vietnam for at least 183 days in a calendar year, or in any 12 consecutive months counted from your first day present.
• Habitual residence. You have a habitual place of residence in Vietnam — including a registered permanent residence, or a fixed-term home lease. This is a separate test: you can be resident on this basis even if your day count is under 183.

The difference is big. A resident is taxed on income arising both inside and outside Vietnam; a non-resident is taxed only on Vietnam-source income. And note what does not by itself decide residency: your visa, your work permit, your employment contract, or a single year’s day count. The habitual-residence limb stands on its own.

What income can Vietnam tax?

For employment, the taxable base is broad: salary and wages, bonuses, and cash or non-cash benefits and allowances, minus the statutory exemptions and deductions. Two points trip people up:

• Salary paid from abroad. If you’re a Vietnamese tax resident, you can’t assume your pay is outside Vietnamese tax just because the payroll or the payer sits overseas — the resident calculation doesn’t turn on where you’re paid. Whether a treaty changes the result is a separate, fact-specific question (see below).
• Benefits. Some allowances and employer-provided perks have special treatment, but the exact 2026 interaction of older guidance with the new law needs checking case by case — don’t assume a benefit is tax-free without confirming it.

Vietnam PIT rates for expats in 2026

For a resident, salary and wage income is taxed on a progressive scale, applied to your taxable income after deductions:

The deductions that reduce that taxable income are also higher for 2026:

If you’re a non-resident, salary income from work performed in Vietnam is taxed at a flat 20%, regardless of where it’s paid. One important caveat: that 20% is specifically the non-resident salary/wage rule. It is not a universal “20% on everything” — other income types (capital, property, business) have their own treatment.

What if you sublet or rent out a property?

If you legally rent out a property (and it isn’t a lodging/accommodation business), the PIT is calculated as the part of your annual rental revenue above a VND 1 billion threshold, taxed at 5%. That threshold was raised from the older VND 500 million figure by Decree 141/2026, effective 1 January 2026. Two things to get right:

• It’s not “5% of all gross rent.” The 5% applies only to revenue above the threshold.
• Multiple properties share one threshold. You don’t get a fresh VND 1 billion allowance per property — the total annual deduction is capped at VND 1 billion across your rental contracts.

VAT can be a separate issue above the relevant threshold, so don’t assume the 5% settles everything. And short-term or serviced “Airbnb-style” letting may be classed as a lodging business with different rules — and it may not even be permitted in your building, which is its own question (see is Airbnb legal in HCMC). If you’re weighing buying a unit to let, start with can foreigners buy property in Vietnam.

Tax code, payroll withholding and annual filing

Working here, you’ll get a Vietnamese tax code (MST) — used across your tax documents and when opening accounts at licensed banks (banks still apply their own KYC, so it’s not a magic bank-opening pass). Keep the same MST across job changes.

The bigger misconception is that monthly payroll withholding closes the matter. It often does for a straightforward single-employer resident — but a direct filing obligation can arise if your salary is paid by an overseas payer, if you have taxable side income, or if you don’t meet the conditions to have your employer finalise on your behalf. Vietnam runs an annual finalisation (quyết toán) after year-end.

Double-tax treaties: relief, not an automatic exemption

Vietnam has double-tax agreements (DTAs) with many countries, and a treaty can allocate taxing rights, reduce tax, or relieve double taxation depending on your country, your income type and the facts. But relief is not automatic — it typically requires a tax-residency certificate from your home country and a treaty-relief application filed through the Vietnam side. Identify the correct Vietnamese tax treatment first, then apply the treaty; and because tie-breaker rules and credits are country-specific, get advice for your treaty rather than assuming an exemption.

Mistakes expats make

The fastest way to get this wrong is to repeat something that used to be true. The common ones:

• “I was here under 183 days, so I’m not resident.” There’s also the rolling-12-month count and the independent habitual-residence test.
• “My overseas employer pays me, so Vietnam can’t tax it.” A resident is taxed on worldwide income, and the resident calculation ignores where you’re paid.
• “The non-resident rate is 20% on all my Vietnam income.” The 20% is the non-resident salary rule for work in Vietnam — other income types differ.
• “The table is still seven bands with an VND 11m deduction.” For the 2026 tax year it’s five brackets and a VND 15.5m personal deduction.
• “Rental tax is just 5% of all my rent above VND 500m.” The threshold is now VND 1 billion, the 5% applies only above it, and several properties share one allowance.
• “Payroll withholding means I never deal with finalisation.” Foreign-paid salary, side income and authorisation conditions can all trigger a personal filing.
• “A treaty automatically stops double tax.” It needs the right treaty, a residence certificate and the relief procedure.

Where to live while work and tax settle

Where you rent is a commute-and-lifestyle decision, not a tax classification — but a fixed-term lease is relevant to the habitual-residence test, so keep yours on file. The areas most working expats shortlist:

• District 1 — the CBD; simplest if your office and clients are downtown (buildings like The Marq).
• Binh Thanh — the riverside work corridor around Vinhomes Central Park, close to the CBD without D1 prices.
• Thao Dien — the established expat hub, green and family-friendly, with an easy run into town.

Frequently asked questions

Do foreigners pay income tax in Vietnam?

Yes — most foreigners working in Vietnam are liable for personal income tax. How much depends on whether you’re a tax resident (taxed on worldwide income) or a non-resident (taxed only on Vietnam-source income, with salary from work in Vietnam at a flat 20%).

Do I pay Vietnam tax if my salary is paid from abroad?

If you’re a Vietnamese tax resident, very likely yes — the resident calculation doesn’t depend on where you’re paid, and residents are taxed on worldwide income. A double-tax treaty may change the outcome, but that’s a separate, fact-specific analysis.

Does a work permit or visa make me a tax resident?

Not by itself. Tax residency is decided by the 183-day day count (calendar year or rolling 12 months) or by having a habitual residence such as a fixed-term lease — independently of your visa or work permit.

Is the non-resident tax rate always 20%?

No. The flat 20% is specifically for a non-resident’s salary from work performed in Vietnam. Other income types — property, capital, business — have their own treatment, so don’t apply 20% to everything.

Does my employer file everything for me?

Often for a simple single-employer resident, yes — but not always. Foreign-paid salary, taxable side income, or not qualifying for authorised finalisation can mean you must file your own annual return. Confirm your situation rather than assuming.
