U.S. taxes for Americans in Vietnam: what to file, and how to catch up.
Ho Chi Minh City, Hanoi and Da Nang draw American teachers, entrepreneurs and Vietnamese-American families, and all of them still file a U.S. return every year. A U.S.-Vietnam tax treaty was signed in 2015 but never took effect, so the foreign earned income exclusion and the foreign tax credit do the work. The details to get right are social insurance, local companies and funds. Most people who fell behind can catch up under the Streamlined procedures, with no penalty if they qualify.
Sound familiar?
- You came to Vietnam to teach English and stayed.
- Your employer pays into Vietnamese social insurance for you.
- You keep savings in a Vietnamese bank’s term deposit.
- Your Vietnamese bank asked for your U.S. tax number.
How does the IRS treat Vietnamese income, accounts and companies?
Accounts go on your FBAR once they add up to more than $10,000. What differs is how the IRS taxes them.
| Item | U.S. treatment | |
|---|---|---|
| Social insurance | Could be treated as social security or as a foreign retirement account the U.S. can tax, and the rules don’t settle which. | Check first |
| Teaching and other wages | Usually covered by the foreign earned income exclusion, up to $132,900 for 2026. Vietnamese tax can be credited instead. | Mostly friendly |
| Term deposits and bank accounts | Interest is taxable for the U.S., and the accounts count toward your FBAR total. | Taxable |
| Vietnamese funds | Usually PFICs (Form 8621), with complex reporting and tax rules. | Watch out |
| Companies in Vietnam | If you own 10% or more of a Vietnamese company, you may need Form 5471 each year, and some of its income can be taxed on your U.S. return. | Watch out |
| Social insurance lump sum | Foreign workers leaving Vietnam can often withdraw their contributions; the payout could be taxable for the U.S. | Plan ahead |
Which Vietnamese investments are PFICs?
Vietnamese open-ended funds and ETFs, sold by fund managers and through banking and brokerage apps. For U.S. tax they’re passive foreign investment companies, or PFICs, with their own reporting and harsh default tax rules.
- Each fund needs its own Form 8621 in most years, and gains can be taxed at the top U.S. rate plus an interest charge, unless an election was made in time.
- Not PFICs: term deposits, shares of individual companies on the Ho Chi Minh City or Hanoi exchanges, and government bonds.
- A company you set up to run a business is a different question: it usually needs Form 5471, whatever it holds.
Is there a U.S.–Vietnam tax treaty?
One was signed in 2015, but it never took effect, so it doesn’t apply to your returns. Until it does, U.S. law does the work:
- The foreign tax credit doesn’t need a treaty. Vietnamese income tax on your salary can be credited against U.S. tax on the same income.
- The foreign earned income exclusion works the same with or without a treaty.
- No social security agreement means a self-employed American owes U.S. self-employment tax, and working for a U.S. company usually means U.S. Social Security withholding.
Vietnam taxes you as a resident once you spend 183 days or more there in a year, or have a permanent home there. Then it taxes your worldwide income, U.S. income included.
When are Vietnamese and U.S. taxes due?
Both tax years run January to December, so each Vietnamese year lines up with one U.S. return.
| Vietnam | United States | |
|---|---|---|
| Tax year | January to December | January to December |
| Annual return | The finalization by the end of April, often done by your employer for you | April 15, moved to June 15 automatically when you live abroad, or October 15 with an extension |
| Paying the tax | Withheld from your salary each month | April 15, even if you file later |
| Foreign accounts | No separate report for most residents | The FBAR, due October 15, filed online |
Foreign tax credit or exclusion: which wins in Vietnam?
- Teachers and others on modest salaries usually use the foreign earned income exclusion; a teaching salary is far below the limit.
- Higher earners paying Vietnamese rates that climb to 35% often do better with the foreign tax credit.
- Families with children often keep the credit, because it allows the refundable part of the U.S. child tax credit, up to $1,700 per child for 2025.
- Freelancers still owe U.S. self-employment tax, even when the exclusion covers the income tax.

A worked example: a teacher in Hanoi
Chloe came to Hanoi to teach in 2018 and now works at an international school. She pays into Vietnamese social insurance through her employer and keeps her savings in a term deposit at a Vietnamese bank. She has never filed a U.S. return.
| Item | How it’s handled |
|---|---|
| Salary | Well under the exclusion, so her U.S. income tax on it is $0. She still has to file to claim it. |
| Social insurance | How it’s treated is unsettled, so we explain the options, including for a lump sum if she leaves. |
| Term deposit | The interest goes on her U.S. return, and the account on the FBAR once she’s over $10,000. |
| Catching up | Three years of returns and six FBARs under the Streamlined procedures, with no penalty if she qualifies. |
Catching up from Vietnam
Most Americans in Vietnam who fell behind without meaning to can catch up under the Streamlined Foreign Offshore Procedures: three years of returns, six years of FBARs and, if you qualify, no penalties. If only FBARs are missing, or you’ve moved back to the U.S., another route may fit better. See every IRS catch-up option for expats, compared.
Common questions
Do I pay U.S. Social Security tax in Vietnam?
Usually not if you work for a local employer. There’s no U.S.-Vietnam social security agreement, though, so self-employment tax can still apply if you work for yourself, and FICA if you work for a U.S. company.
Without a tax treaty, will I be taxed twice?
Usually not. The U.S. foreign tax credit works without a treaty, so Vietnamese income tax you pay generally reduces your U.S. tax on the same income.
When does Vietnam tax me as a resident?
Generally once you spend 183 days or more there in a year, or have a permanent home there. Then Vietnam taxes your worldwide income, and the U.S. exclusion or credit keeps you from paying twice.
I teach in Vietnam. Will I owe U.S. tax?
Usually not on your salary: the foreign earned income exclusion normally covers it. You still have to file to claim it, and an FBAR if your accounts topped $10,000.
Is a social insurance lump sum taxable in the U.S.?
It could be. How it’s treated depends on how the account is classified for the U.S., which isn’t settled. Plan the timing with us before you withdraw it.
How do you handle dong amounts?
We convert using the correct IRS exchange rates for each year and account. It’s routine for us.
