FBAR and the IRS $10,000 Rule: What US-Based Vietnamese Must Report

FBAR filing trips up thousands of Vietnamese Americans every year, usually because nobody told them a dormant account in Hồ Chí Minh counts. This guide explains the $10,000 threshold, which accounts you report, the October deadline, and why sending money to family in Vietnam is a completely separate question.

Your mother in Đà Nẵng opened a savings account in your name years ago. You have barely touched it. It sits there earning a little interest, and you have never once thought of it as a US tax matter.

That account may put you inside the FBAR filing rules, and the penalties for ignoring it are heavier than most people expect.

This confuses people because the number $10,000 shows up in several unrelated US rules at once. Some of those rules apply to your bank, some to businesses, and only one of them applies to accounts you hold in Việt Nam. Sorting out which is which takes about ten minutes and can save you a great deal of trouble.

FBAR stands for Report of Foreign Bank and Financial Accounts, filed as FinCEN Form 114. It goes to the Financial Crimes Enforcement Network, part of the Treasury, and it never gets attached to your tax return.

That distinction matters. FBAR filing is a disclosure, not a tax. Reporting a Vietnamese account creates no US tax bill on its own, and the money in it stays yours.

The obligation applies to US persons, which covers citizens, green card holders, and resident aliens for tax purposes. Where you live makes no difference, so a Vietnamese American in Houston and a US green card holder who moved back to Hà Nội face the same rule.

The $10,000 Threshold Behind FBAR Filing

You must file if the total value of all your foreign financial accounts went above $10,000 at any point during the calendar year. Most people read that too narrowly, so it is worth taking apart.

How the Aggregate Test Works for FBAR Filing

The threshold is combined, not per account. Holding $6,000 at Vietcombank and $5,000 at Techcombank puts you over the line even though neither account alone comes close.

It also tests the highest point during the year rather than the balance on 31 December. If a property sale pushed an account to VND 400 million in March and you spent it down to almost nothing by December, the obligation was still triggered in March.

Once you cross the threshold, you report every qualifying account, including the small ones that had nothing to do with pushing you over. You convert balances to US dollars using the Treasury’s official year-end exchange rate rather than the rate you happened to get on a transfer.

Which Vietnamese Accounts Count Toward FBAR Filing

Vietnamese Americans routinely miss accounts because they do not think of them as theirs in any active sense. The categories that catch people out include:

• Savings and current accounts at Vietnamese banks such as Vietcombank, BIDV, VietinBank, Techcombank, ACB, or Sacombank
• E-wallet balances at providers like MoMo, ZaloPay, or ViettelPay, since these usually qualify as foreign financial accounts
• Accounts opened in your name by parents or relatives, even if you have never used them.
• Joint accounts with a spouse, sibling, or parent in Việt Nam
• Accounts where you hold only signature authority, such as a parent’s account you can sign on, with no ownership at all
• Vietnamese investment, securities, and some insurance products with a cash value

The signature authority point deserves emphasis. You can owe an FBAR filing on money that is not yours and that you never spent, purely because your name lets you sign.

Sending Money to Vietnam Does Not Trigger FBAR Filing

This is the single biggest misunderstanding among US-based Vietnamese senders, and clearing it up removes most of the anxiety.

FBAR filing attaches to accounts you own or control abroad. Transferring $15,000 from your Bank of America account to your brother’s account in Cần Thơ creates no FBAR obligation for you at all, because the receiving account belongs to him.

Your bank will report large transactions to FinCEN under separate Bank Secrecy Act rules, which happens automatically and requires nothing from you. Vietnam, for its part, does not tax inward family remittances received by individuals, so your relatives are not walking into a tax bill either.

Where senders do create an obligation is by keeping their own account in Việt Nam as a staging point. Moving money into an account in your own name, then distributing it locally, puts that account squarely inside the rules.

FBAR Filing Deadlines and Penalties

The FBAR follows the tax calendar without being part of it. The report for a given calendar year falls due on 15 April of the following year, with an automatic extension to 15 October that requires no request and no form.

For 2025 accounts, that means the window runs to 15 October 2026. There is no further extension beyond that date, and filing happens electronically and free of charge through the BSA E-Filing System.

Penalties are where this gets serious. Non-willful violations currently carry a penalty in the region of $16,000 per violation, adjusted for inflation each year, while willful violations reach the greater of roughly $165,000 or 50% of the account balance, with criminal exposure in the worst cases. Those are ceilings rather than automatic outcomes, and the IRS has procedures for people who genuinely did not know, but the range explains why practitioners treat this form seriously.

If you have missed past years, the Streamlined Filing Compliance Procedures and the Delinquent FBAR Submission Procedures exist precisely for honest oversights. Talk to a cross-border tax professional before filing anything late, because choosing the wrong route can cost you the relief.

Other $10,000 Rules People Confuse With FBAR Filing

Several US rules share that number, which is why so many people arrive at FBAR filing questions already tangled up.

Bank Reports and Form 8300

Your bank files a Currency Transaction Report when you deposit or withdraw more than $10,000 in cash in a day. Businesses file Form 8300 when they receive over $10,000 in cash from a customer. Neither is your filing obligation, and neither has anything to do with foreign accounts.

Form 8938 Sits Above FBAR Filing

Form 8938 reports specified foreign financial assets to the IRS with your tax return, under FATCA. Thresholds start at $50,000 on the last day of the year, or $75,000 at any point, for a single filer living in the US, and rise to $200,000 and $300,000 for a single filer living abroad. Married couples get roughly double. Filing one form never satisfies the other, so people over both thresholds file both.

Money Coming From Family in Vietnam

If relatives in Việt Nam gift you more than $100,000 in a year, you report it on Form 3520. This one catches families handling an inheritance or a property sale in Việt Nam, and again, reporting does not create tax on the gift itself.

The 1% Remittance Tax Alongside FBAR Filing

A newer rule affects how you send rather than what you report. Since 1 January 2026, a 1% federal excise tax applies to outbound transfers funded with cash, money orders or cashier’s checks, introduced under Section 4475.

Transfers funded from a US bank account, debit card, or credit card fall outside it. Handing $1,000 in cash across a counter costs you an extra $10 that the same transfer sent digitally would not. For families who have always paid cash at an agent location, switching the funding method is the whole fix.

How ZoltMoney Fits Around Your FBAR Filing

ZoltMoney moves money digitally from a bank account or card, so transfers through the platform sit outside the cash-funded remittance tax. Your recipient in Việt Nam receives VND in their bank account or e-wallet, with no crypto wallet and no blockchain knowledge needed on either side.

Clean records help more than people realise at filing time. Transparent pricing with the real exchange rate shown before you confirm means your transfer history reads clearly a year later, when an accountant asks what moved and why. If you want the practical mechanics of the corridor, our guide to sending money from the US to Vietnam covers payout options, timing and recipient details.

None of this replaces advice from a qualified professional. What it does is keep the sending side simple, so the only thing left to think about is whether an account in your own name crosses the threshold. You can start a transfer at ZoltMoney on the web, on Android, or on iOS.

FAQ

Does sending money to family in Vietnam require FBAR filing?

No. Sending money to an account belonging to your parents, siblings, or other relatives creates no FBAR obligation for you, because the account is not yours. The rule attaches to foreign accounts you own or can sign on to. Your US bank handles its own reporting to FinCEN automatically, and you do not file anything for an ordinary family transfer.

Do I need to file an FBAR for an account my parents opened in my name?

Very likely, yes, if your name is on it. Ownership and signature authority both count, regardless of whether you opened the account, use it, or even knew about it. Add its highest balance during the year to your other foreign accounts, and if the combined total passes $10,000 at any point, the account belongs on your report.

Does FBAR filing mean I owe US tax on my Vietnamese savings?

No. The FBAR is a disclosure filed with FinCEN, not a tax return, and reporting an account creates no tax on the balance. Interest earned in a Vietnamese account is separately taxable income on your US return, which is a different obligation. Many people report accounts every year and owe nothing extra as a result.

Do MoMo and ZaloPay balances count for FBAR filing?

Generally yes. Vietnamese e-wallet accounts usually qualify as foreign financial accounts, and their balances count toward the $10,000 aggregate test alongside your bank accounts. People overlook them because the amounts feel small, but the threshold is combined across everything. Check the highest balance each wallet reached during the year rather than what sits there now.

What if I have missed FBAR filing for several years?

You have options, and coming forward voluntarily usually beats waiting. The Streamlined Filing Compliance Procedures cover non-willful failures, and the Delinquent FBAR Submission Procedures apply when you reported all income but missed the form. Both have conditions, and picking the wrong one can forfeit the relief, so speak to a cross-border tax professional before you file anything.
