Living and working internationally opens up enormous professional and personal opportunities. It also opens up a compliance requirement that many global professionals discover only after it is already a problem: the FBAR.
The Report of Foreign Bank and Financial Accounts (FBAR) must be filed annually by any US person who held foreign financial accounts with an aggregate value exceeding $10,000 at any point during the calendar year. The rule applies regardless of where you live, whether you filed US taxes, or whether the accounts earned any income.
The penalties for getting it wrong are severe. Willful violations can reach $165,353 or 50% of the account balance per violation. Even non-willful violations now carry penalties up to $16,536 per report following the Supreme Court's 2023 decision in Bittner v. United States. According to the IRS's official FBAR guidance page, civil and criminal penalties may both apply for failures to properly file when required.
Here are the five mistakes that most commonly create exposure for global professionals.
1. Assuming the $10,000 Threshold Applies to Each Account Separately
This is the most common misunderstanding. The $10,000 threshold is an aggregate figure across all foreign accounts, not a per-account limit.
If you have three accounts in different countries, each holding $4,000, and the balances were held simultaneously at any point during the year, the aggregate reached $12,000. All three accounts must be reported. The threshold is crossed at the moment the combined total exceeds $10,000, even if no single account reaches that amount.
Many professionals with multiple smaller accounts believe they are under the filing threshold when they are not.
2. Not Reporting Accounts You Do Not Actively Use
The filing obligation attaches to accounts in which you have a financial interest or signature authority, not only accounts you actively use or from which you receive income.
This means accounts opened years ago that you forgot about, accounts where funds have been sitting idle, accounts in your name at a foreign employer for payroll purposes, and joint accounts where you are listed but your spouse manages the funds. If the account exists, you hold a qualifying interest in it, and the aggregate crosses $10,000, it must be reported.
Dormant and forgotten accounts are among the most common sources of unintentional FBAR violations.
3. Missing the Filing Deadline or Confusing It With the Tax Return Deadline
The FBAR is not part of your federal tax return. It is filed separately through the FinCEN BSA E-Filing System, not through the IRS directly. The annual deadline is April 15, with an automatic extension to October 15 available without application.
Many filers assume that completing their tax return satisfies the FBAR requirement, or that the two deadlines are the same. They are not. The FBAR is a standalone obligation with its own filing system, its own deadline, and its own penalty structure.
Filing your taxes on time does not protect you from FBAR penalties if the FBAR itself was not filed.
4. Not Correcting Past Failures Before They Become Bigger Problems
Discovering that you should have filed FBARs in previous years does not automatically mean severe penalties apply. The IRS offers compliance programs that may help eligible taxpayers correct past filing issues.
The key factor is timing. Taking action before the IRS initiates contact can significantly improve available options. For expats dealing with past non-compliance or complex foreign account reporting, professional guidance can help navigate the process more effectively.
Understanding the requirements for FBAR filing early can help expatriates identify reporting obligations before they become costly compliance issues.
Based on guidance from the experts at MyExpatTaxes, the FBAR rules are more broadly applicable than most expats initially realize, and the combination of the aggregate threshold, signature authority rules, and the filing structure separate from the tax return creates multiple points where professionals inadvertently fall out of compliance.
5. Failing to Report Accounts in Employer or Corporate Structures
Global professionals who work through foreign subsidiaries, hold accounts in their employer's name with their signature authority, or own foreign corporate entities with bank accounts may have FBAR obligations that extend beyond their personal accounts.
Signature authority over a corporate account means you can instruct the bank to move funds, even if the money is not yours. That signature authority triggers a filing requirement if the account crosses the threshold.
Many professionals in senior international roles carry this obligation without realizing it, particularly when moving between countries and employer structures.
Why FBAR Compliance Matters Before It Becomes a Penalty Problem
FBAR compliance is not a matter of interpretation. The requirement is specific, the penalties are significant, and the IRS has expanded its mechanisms for identifying undisclosed foreign accounts through FATCA data sharing with foreign banks.
Understanding the five mistakes above and checking your own situation against each of them is the most practical step any global professional can take to make sure they are on the right side of an obligation that carries real consequences.
FBAR Filing Questions Global Professionals Should Ask
Who needs to think about FBAR filing?
FBAR filing can apply to US citizens, resident aliens, and other US persons with qualifying foreign financial accounts. The issue is not limited to people living in the United States, and it can affect expats, internationally mobile professionals, founders, executives, and people with signature authority over foreign accounts. Anyone with overseas banking exposure should check the aggregate account value test rather than assuming the rule does not apply.
Why does the aggregate account rule create so many filing mistakes?
Many people think the $10,000 threshold applies account by account, but the FBAR test looks at the combined value of foreign accounts. That means several smaller accounts can trigger the requirement even when no single account looks large on its own. For founders, consultants, and globally mobile workers, this can be easy to miss if accounts are spread across countries, employers, or old banking relationships.
How can business owners and founders reduce FBAR risk?
Business owners should maintain a clear inventory of foreign accounts, including personal, company, and dormant accounts, as well as accounts where they hold only signature authority. They should also document who has access, the highest balance, and whether any accounts are tied to overseas entities or subsidiaries. The practical goal is to create a repeatable annual check rather than rediscovering the issue at tax-filing time.
What should someone do if they missed FBAR filings in previous years?
The safest first step is usually to avoid guessing and get qualified tax or compliance advice before filing late reports. Past non-compliance does not automatically mean the worst penalty outcome, but timing and intent can matter. Acting before the IRS contacts you may preserve more options than waiting until the issue is discovered externally.
Why does signature authority matter for senior professionals?
Signature authority can create a reporting obligation even when the account balance does not personally belong to the professional. This is especially relevant for executives, finance leaders, founders, and employees who can approve or direct movement of funds from foreign corporate accounts. The risk is that people often think only ownership matters, when FBAR rules can also capture control or authority over an account.
