How Vietnam decides your tax: two doors, no remittance lever
Door 1: 183 days
183+ days in the calendar year or any rolling 12 months from arrival = tax resident. The rolling window is the trap β splitting a stay across two calendar years doesn't reset the clock.
Door 2: a permanent base
A residence card or a lease of 183+ days can make you a resident even with fewer days of presence β signing a year-long apartment lease has tax consequences.
Once resident, Vietnam taxes your worldwide income β unlike Thailand's remittance basis, it does not matter where the money is paid or whether it ever touches a Vietnamese bank. "I get paid offshore so it's not taxable here" is the single most common β and most expensive β nomad misconception in Vietnam, and the tax authority is actively pursuing it.
Vietnam's new 5-bracket rates (2026)
| Taxable income (VND/month) | Rate |
|---|---|
| Up to 10M | 5% |
| 10M β 30M | 10% |
| 30M β 60M | 20% |
| 60M β 100M | 30% |
| Over 100M | 35% |
Reduced from 7 brackets under PIT Law 109/2025/QH15, applying from the 2026 tax year. Applied after deductions: β«15.5M/month personal + β«6.2M/month per registered dependent. Non-residents instead pay a flat 20% on Vietnam-sourced income with no deductions.
Separately for the self-employed, the same law raises the annual revenue below which a household or individual business is exempt from VAT and PIT from β«100M to β«500M/year β a distinct regime from the employment brackets modelled above.
Living cost reality check
The tax math is only half the picture β purchasing power is the other half. Typical comfortable monthly budgets (single person, 2026 ballpark):
- Da Nang: $900β1,400 β beachside apartment, eating out daily, coworking
- Ho Chi Minh City: $1,300β2,200 β central serviced apartment, gym, mixed lifestyle
- Hanoi: $1,100β1,800 β between the two; cooler winters, lower rent than HCMC
Vietnam undercuts even Thailand on living costs β and the new 2026 deductions mean a single nomad pays nothing until roughly $7,200/year of income, and an effective rate of only ~10% at $60k. The tax is real, but it's modest; what bites is not knowing you owed it.
Frequently asked questions
Q. My employer and clients are all abroad and I'm paid offshore. Still taxed?
A. If you're a resident β yes, in full. Vietnam taxes residents on worldwide income regardless of where it's paid or kept. This is the opposite of Thailand's remittance basis and the most common nomad misconception here.
Q. I stayed 100 days but signed a one-year lease. Resident?
A. Potentially yes β a lease of 183+ days (or a residence card) is an independent trigger for residency. Some people in this position can claim non-residency by proving tax residency elsewhere, but that requires documentation, not assumption.
Q. I already pay tax in my home country. Double taxed?
A. Vietnam has ~80 DTAs that generally credit foreign tax paid against Vietnamese liability. Note for Americans: there is no comprehensive USβVietnam income tax treaty, so US citizens rely on the FEIE and foreign tax credits on the US side.
Q. When and how do I file?
A. The tax year is the calendar year; annual finalization is due around 31 Marchβearly May of the following year depending on filing channel. You register with the tax authority (GDT) for a tax code first. Quarterly provisional filings can apply to self-declared income.
Q. What changed in 2026?
A. Law 109/2025/QH15: brackets cut from 7 to 5, the top 35% rate now starts above β«100M/month (was β«80M), personal deduction up to β«15.5M/month (β«186M/year) and dependents to β«6.2M β most people pay meaningfully less than under the old table. Separately, the tax-free revenue threshold for household and individual businesses rises from β«100M to β«500M per year. The salary and business-income provisions apply from 1 January 2026, with the law in full force from 1 July 2026, and the implementing Circular is still pending β so the detailed method may change.

The law takes full effect on 1 July 2026, but the salary and business-income provisions β the simplified 5-bracket progressive schedule (top rate 35% above VND 100 million/month) and the higher personal deductions (VND 15.5 million/month for the taxpayer, VND 6.2 million/month per dependent) β apply from the 2026 tax year (1 January 2026). The same law also raises the VAT/PIT exemption threshold for household and individual businesses from VND 100 million to VND 500 million of annual revenue. Because the implementing Circular has not yet been issued, the detailed calculation method may still change.
