Wise can count as a foreign bank account for FBAR purposes, but only some of the money you hold inside the app actually triggers a filing. What matters is where Wise physically holds each balance. USD balances routed through domestic partners like JPMorgan Chase or Community Federal Savings Bank sit inside the U.S. financial system and generally don’t count. Euros, pounds, and other non-USD balances held through Wise Europe SA in Brussels or TransferWise Ltd in the United Kingdom are foreign financial accounts, and once your combined foreign account values cross $10,000 at any point in the year, you owe an FBAR.
Which Wise Balances Are Actually Foreign
Wise is not a bank. Wise US Inc. is registered with FinCEN and licensed as a money transmitter state by state, with Community Federal Savings Bank filling in where Wise doesn’t hold its own license.1Wise Help Centre. How Is Wise Regulated in Each Country and Region Wise Europe SA operates from Brussels under authorization from the National Bank of Belgium.2Wise. Online Money Transfers – International Banking Features
Your reporting obligation follows the institution’s location, not yours. When you open a USD balance, deposits typically route to JPMorgan Chase or Community Federal Savings Bank in New York. Those are domestic accounts. When you hold euros, Wise assigns you a Belgian IBAN through Wise Europe SA. That balance is in Belgium regardless of where you logged in from.3Wise Help Centre. Wise Bank Details
The same user can hold both types at once. If you only keep dollars funded by a domestic transfer, you probably have no foreign account to report through Wise. Add a euro balance, a pound balance, or any other non-USD currency, and the foreign account rules apply to that portion.
There is one wrinkle with dollars. If someone sends you USD by SWIFT wire, the funds route through TransferWise Ltd in the United Kingdom rather than the domestic channel.3Wise Help Centre. Wise Bank Details A dollar balance that touched the UK entity can be treated as a foreign account even though the currency is dollars. If you receive international wires into Wise, check the routing.
The $10,000 FBAR Threshold
The Bank Secrecy Act requires anyone with a financial interest in or signature authority over foreign financial accounts to file FinCEN Form 114 — the FBAR — if the combined value of all foreign accounts exceeds $10,000 at any point during the calendar year.4Internal Revenue Service. Report of Foreign Bank and Financial Accounts (FBAR) The threshold is aggregate, not per account. If your Wise euro balance peaks at $6,000 and you also have $5,000 in a foreign brokerage account elsewhere, you’ve crossed the line and must report both.
A foreign financial account includes any account maintained with a financial institution physically located outside the United States, and the definition reaches entities “performing the services of a financial institution.” That covers Wise Europe SA holding customer funds in Belgium even though Wise isn’t a traditional bank.5Internal Revenue Service. Comparison of Form 8938 and FBAR Requirements What you report is the maximum value of each account during the year, not the income it produced.
To convert non-USD balances into dollars, use the Treasury Reporting Rates of Exchange published by the Bureau of the Fiscal Service, applying the rate for the last day of the calendar year being reported.6U.S. Treasury Fiscal Data. Treasury Reporting Rates of Exchange
Finding Your Peak Balance
Wise doesn’t send you a year-end foreign account statement. You’ll need to work through your own transaction history in the app, one currency at a time. The peak might not be December 31; it could be any day the balance was highest. If a large euro transfer landed in March and you spent most of it by December, the March high-water mark is what you report. Download your transaction history and keep it, because you’re required to hold onto records supporting your FBAR for five years from April 15 of the following year. Those records should include the account name and number, institution name and address, account type, and maximum value.7Financial Crimes Enforcement Network. Record Keeping Requirements
The Schedule B Question People Miss
Even below the $10,000 FBAR threshold, if you had any foreign financial account during the year, you have to answer the foreign account questions on Schedule B of Form 1040. Part III asks whether you had a financial interest in or signature authority over a foreign account. If yes, you check the box, indicate whether you’re required to file an FBAR, and list the countries where the accounts are located.8Internal Revenue Service. Schedule B (Form 1040) For a Wise euro balance, that’s Belgium. For pounds held through the UK entity, that’s the United Kingdom.
Schedule B is also required if you had more than $1,500 in taxable interest or ordinary dividends, or if you had any foreign account at all.9Internal Revenue Service. Instructions for Schedule B (Form 1040) Many Wise users skip this because they think of the app as a payment tool rather than an account they hold at a foreign institution. That’s the kind of oversight that draws scrutiny.
Form 8938 Is Separate, With Higher Thresholds
The FBAR is not the only foreign account form. FATCA requires you to file IRS Form 8938 with your income tax return if your specified foreign financial assets exceed thresholds that depend on filing status and residence:10Internal Revenue Service. Do I Need to File Form 8938, Statement of Specified Foreign Financial Assets
- Single filer living in the U.S.: assets exceed $50,000 on the last day of the year or $75,000 at any point.
- Married filing jointly in the U.S.: $100,000 last day or $150,000 at any point.
- Single filer living abroad: $200,000 last day or $300,000 at any point.
- Married filing jointly abroad: $400,000 last day or $600,000 at any point.
A foreign financial institution for FATCA purposes includes any non-U.S. entity that accepts deposits in the ordinary course of banking or holds financial assets for others as a substantial part of its business.11Internal Revenue Service. Instructions for Form 8938 Wise Europe SA fits, so its balances count toward these thresholds alongside your other foreign holdings. Filing one form doesn’t satisfy the other. You may end up filing both.5Internal Revenue Service. Comparison of Form 8938 and FBAR Requirements
Deadlines
The FBAR is due April 15 following the calendar year being reported. Miss that date and you get an automatic extension to October 15 without having to request it.4Internal Revenue Service. Report of Foreign Bank and Financial Accounts (FBAR) The FBAR is filed electronically through FinCEN’s BSA E-Filing System, not with the IRS.12Financial Crimes Enforcement Network. How Do I File the FBAR
Form 8938 goes with your income tax return. If you get a tax filing extension, the Form 8938 deadline moves with it. If you’re not required to file a tax return at all, you don’t file Form 8938 regardless of your foreign asset values.13Internal Revenue Service. Summary of FATCA Reporting for U.S. Taxpayers
Penalties for Not Filing
The statutory base penalty for a non-willful FBAR violation is $10,000 per account per year.14Office of the Law Revision Counsel. 31 USC 5321 – Civil Penalties These penalties are adjusted annually for inflation. As of the most recent published adjustment in early 2025, the non-willful ceiling had risen to $16,536 per violation.15Federal Register. Inflation Adjustment of Civil Monetary Penalties If the IRS finds the violation willful, the penalty rises to the greater of $100,000 or 50 percent of the account balance at the time of the violation, and criminal prosecution is possible.
A reasonable cause exception exists: if your failure was due to reasonable cause and you properly reported the account balance, no penalty applies. Arguing you didn’t know Wise counted gets harder each year as awareness of fintech reporting spreads.
Form 8938 carries its own separate penalty structure. Failure to file draws a $10,000 penalty. If you still haven’t filed 90 days after an IRS notice, an additional $10,000 accrues for each 30-day period of continued non-filing, up to $50,000 more. Any tax underpayment tied to an undisclosed foreign asset also triggers a 40 percent accuracy-related penalty.11Internal Revenue Service. Instructions for Form 8938
Catching Up on Missed FBARs
If you’ve been using Wise for years without realizing your foreign currency balances needed reporting, there are two main paths to fix it before the IRS finds you.
If you properly reported all the income from your foreign accounts on your tax returns and only failed to file the FBAR itself, you can submit late FBARs through the BSA E-Filing System with a statement explaining why they’re late. The IRS generally won’t impose penalties if you’ve paid all tax due on the income from those accounts, you’re not under examination or criminal investigation, and the IRS hasn’t already contacted you about the missing FBARs.16Internal Revenue Service. Delinquent FBAR Submission Procedures
If you also owe unreported tax on foreign account income, the Streamlined Domestic Offshore Procedures give U.S. residents a path when the failure was non-willful, meaning it resulted from negligence, inadvertence, mistake, or a good-faith misunderstanding of the law. You certify the non-willful nature of your failure, and you can’t use the program if the IRS has already started a civil examination of any of your returns or if you’re under criminal investigation.17Internal Revenue Service. Streamlined Filing Compliance Procedures
Both programs close once the IRS contacts you first. For Wise users who genuinely didn’t realize they held foreign accounts, the non-willful certification is usually straightforward, but an incorrect certification creates its own problems, so it’s worth running the situation past a tax professional before filing.
The fastest way to size up your own exposure is to open Wise, look at every currency balance you hold, check the bank details each one shows, and note which ones list a non-U.S. institution. That short list decides whether you owe an FBAR, a Form 8938, a Schedule B answer, or all three.
