Do Americans Pay Taxes in Vietnam? A Cross-Border Tax Guide

Americans living in Vietnam may have tax and reporting obligations in both countries. The important distinction is between being required to report income and actually owing additional tax after exemptions, deductions and credits. Those are not the same question.

A useful plan starts with your residence, the type and source of each income stream, and the timing of the two countries' tax calculations. It does not start by assuming the Foreign Earned Income Exclusion solves everything.

You Remain Within the US Tax System While Abroad

US citizens and US resident aliens generally report worldwide income, including income earned while living in Vietnam. Whether a return is required and how much tax is due depend on the applicable filing rules and reliefs. Moving abroad does not, by itself, end US tax residency for a green-card holder. See the IRS tax guide for citizens and resident aliens abroad.

Keep salary, consulting receipts, pensions, dividends, rent and gains separate in your records. Different income types can have different treatment even when they arrive in the same bank account.

Does Vietnam Also Tax You?

Vietnam distinguishes tax residents from nonresidents. The residence tests include presence for at least 183 days in a calendar year or in the relevant 12 consecutive months from first arrival, as well as habitual-residence conditions. A home or lease should be assessed under those detailed conditions, including evidence of residence elsewhere; it is not accurate to say that any lease automatically settles the question.

Residents are generally assessed on taxable income arising inside and outside Vietnam, while nonresidents are generally assessed on Vietnam-source taxable income. The governing provisions are Articles 3–5 of Decree 253/2026/ND-CP. Have a Vietnamese tax professional apply the tests to your arrival date, travel record and accommodation rather than relying on nationality or visa status alone.

The Foreign Earned Income Exclusion: Useful, but Limited

The maximum FEIE is US$130,000 for tax year 2025 and US$132,900 for tax year 2026, per qualifying person. A partial qualifying year can reduce the limit. These are tax-year amounts, not an allowance based on the year in which you happen to file. The IRS explains the calculation and proration.

You need qualifying foreign earned income, a foreign tax home and either the applicable bona fide residence test or the physical presence test. The latter generally requires 330 full days in foreign countries during a consecutive 12-month period; days merely outside the United States are not always qualifying days. See the Form 2555 instructions and physical presence guidance.

Qualifying self-employment service income can be eligible. The exclusion does not, however, remove US self-employment tax. Dividends, interest, investment gains and pension payments are not turned into foreign earned income because you receive them abroad. Nor does working for a US company automatically prevent foreign-source earned income: the location of the services matters. The IRS distinguishes these categories in its FEIE overview and foreign earned income guidance.

Foreign Tax Credits: Compare the Whole Calculation

A foreign tax credit may offset eligible foreign income taxes against US tax, subject to limits including income source and tax category. You cannot also claim a credit for foreign taxes attributable to income excluded under the FEIE. Claiming the exclusion does not automatically eliminate every possible foreign tax credit on other income.

Compare the alternatives using the actual income mix, foreign tax paid or accrued, carryovers and future plans. Neither the credit nor the exclusion is always the better answer. See IRS Publication 514.

Vietnamese Tax Is Not Determined by Your US Election

A US exclusion does not decide whether Vietnam taxes your salary. Vietnamese liability follows Vietnamese rules. For resident employment income, the 2026 framework uses five progressive rates from 5% to 35%; the bands apply to assessable income, not simply gross salary. The Government's July 2026 guidance sets out the current schedule.

Business receipts, investment income, property income and gains need separate classification. For the 2026 and 2027 tax years, Resolution 43/2026/QH16 provides a 30% reduction in personal income tax payable on business income for resident individuals with annual revenue not exceeding VND 10 billion. That relief is specific to qualifying business income and does not replace the employment-income schedule above. There is no single 20% rule covering every resident business owner or contractor. Obtain a calculation under the rules applicable to your activity and tax year.

Vietnam does not appear on the IRS list of US income tax treaties in force reviewed for this article. Do not assume a treaty exemption or confuse FATCA information-sharing arrangements with a comprehensive income tax treaty. Domestic foreign tax relief may still apply.

FBAR and Form 8938 Are Separate Obligations

FBAR: a US person generally must report foreign financial accounts when the aggregate value exceeds US$10,000 at any time during the calendar year and the financial-interest or signature-authority conditions apply. It is an aggregate threshold, not US$10,000 per account, and the report is separate from the income tax return. See FinCEN's FBAR guidance.

Form 8938: for individuals who meet the IRS definition of living abroad, the usual thresholds are over US$200,000 at year-end or US$300,000 at any time for a return other than a joint return, and over US$400,000 or US$600,000 respectively for a joint return. Different thresholds apply when the overseas conditions are not met. Form 8938 is generally not required if an income tax return is not required. See the IRS reporting rules.

Foreign companies, partnerships, trusts and investments may also require forms such as 5471, 8865, 3520 or 8621, depending on ownership and transactions. Account reporting is not a substitute for checking those structures.

Structuring Options Need Both Countries' Input

Before choosing salary versus dividends, retaining company profits, establishing a trust or purchasing a policy, ask the US and Vietnamese advisers to work from the same facts. A structure that appears efficient locally may have a different US classification or reporting cost.

A revocable trust can help with administration, but it does not by itself remove its assets from the settlor's US gross estate. Offshore insurance is not automatically estate-tax-free either. The IRS explains retained interests, revocable trusts and insurance ownership.

Tax Planning Is Ongoing, Not One-Off

Revisit the plan before a move, a business sale, a large distribution or retirement. Keep a shared record of travel days, income by source, account balances, entity interests and tax payments. That gives each adviser a consistent starting point and helps identify timing mismatches before deadlines arrive.

Frequently Asked Questions

Does paying Vietnamese tax mean I can stop filing in the US?

No. Filing obligations, foreign tax relief and the final amount due are separate questions. Check the US return and information-reporting requirements even when credits eliminate additional income tax.

Does the FEIE cover investment income or self-employment tax?

No. It is relief for qualifying foreign earned income. Eligible self-employed service income can qualify for income-tax relief, but the exclusion does not remove self-employment tax.

Is the FBAR threshold the same as Form 8938?

No. The thresholds, assets covered and filing processes differ. Depending on the facts, you may need both.

What happens if I missed earlier filings?

Do not assume that simply filing the current year resolves earlier omissions. Ask a qualified US tax adviser which correction procedure applies. Penalties and relief depend on the facts and current rules.
