Does My Startup Have to Report Its Foreign Bank Accounts?

Your startup recently expanded internationally.

Perhaps you opened a bank account for a foreign subsidiary. Maybe you hired employees overseas or began serving customers in another country. You might even have signing authority over an affiliate’s foreign bank account.

At first, these seem like ordinary business decisions. However, opening or controlling a foreign financial account can create reporting obligations under US law, even if the company owes no additional tax.

Many founders assume these rules apply only to individuals with offshore accounts. Others believe filing one international reporting form satisfies every requirement.

Neither assumption is correct.

Depending on your circumstances, your company or even individual officers may need to file separate reports with different government agencies. Understanding these requirements early can help prevent costly penalties and compliance problems.

Why Foreign Account Reporting Matters

The United States requires certain taxpayers to disclose foreign financial accounts and other specified foreign financial assets.

The purpose is to improve transparency and discourage the concealment of offshore assets.

For startups operating internationally, these reporting rules often become relevant much sooner than founders expect.

Opening a foreign bank account, creating an overseas subsidiary, or granting signature authority to company officers may all trigger reporting obligations.

Importantly, these requirements generally focus on reporting rather than taxation.

A company may have no additional tax liability while still being required to file information reports.

Ignoring those obligations can result in significant penalties.

What Is an FBAR?

The Foreign Bank Account Report, commonly known as the FBAR, is filed electronically as FinCEN Form 114.

A US person, including a US business entity, may be required to file an FBAR if it has a financial interest in or signature authority over one or more foreign financial accounts.

The reporting threshold is relatively low.

An FBAR filing is generally required if the combined value of all qualifying foreign financial accounts exceeds $10,000 at any point during the calendar year.

The key point is that the rule looks at the highest aggregate balance during the year rather than the year-end balance or average account value.

The FBAR is generally due on April 15, with an automatic extension to October 15.

What Is FATCA Reporting?

FBAR is not the only reporting requirement.

Certain taxpayers may also have reporting obligations under the Foreign Account Tax Compliance Act (FATCA) using IRS Form 8938.

Unlike the FBAR, Form 8938 covers more than foreign bank accounts.

Depending on the circumstances, it may also include foreign securities held outside US financial accounts, interests in certain foreign entities, and other specified foreign financial assets.

Because the filing thresholds and reporting rules differ from the FBAR, founders should evaluate each requirement separately rather than assuming they operate the same way.

Why FBAR and FATCA Are Separate Requirements

One of the most common compliance mistakes is believing that filing one form satisfies both reporting regimes. It does not.

The FBAR and Form 8938 are administered under different legal frameworks, use different filing procedures, and apply different reporting thresholds.

A company or individual may be required to file one, both, or neither depending on the facts.

Completing only one filing when both are required can still result in compliance issues.

For companies operating internationally, both reporting regimes should be reviewed independently each year.

Signature Authority Can Create Personal Filing Obligations

Many founders focus only on accounts owned by the company. However, ownership is not the only factor that matters.

An individual who has signature authority over a foreign financial account may also have an independent FBAR filing obligation, even if they do not personally own the funds.

This situation commonly arises when founders, chief financial officers, or other executives are authorized to manage foreign subsidiary bank accounts.

As companies expand internationally, it becomes increasingly important to identify who has authority over each account and whether separate personal reporting obligations apply.

Ignoring signature authority can leave both the company and individual officers exposed to compliance risks.

Why Early Planning Matters

Foreign reporting obligations often arise as a by-product of business growth rather than intentional tax planning.

A company may establish an overseas subsidiary, hire international employees, or expand into foreign markets without realizing that additional reporting requirements accompany those decisions.

Developing a process for identifying foreign accounts, tracking balances, documenting account authority, and reviewing annual filing obligations can significantly reduce compliance risk.

Waiting until tax season often makes the process more complicated.

A proactive review allows companies to gather the necessary information before filing deadlines approach.

Common Founder Mistakes

• Assuming only individuals must file FBAR reports: US companies can also have FBAR filing obligations when they have qualifying foreign financial accounts or signature authority.
• Believing FBAR and Form 8938 are the same filing: These are separate reporting regimes with different rules, thresholds, and filing procedures. Filing one does not automatically satisfy the other.
• Ignoring signature authority over foreign accounts: Officers and employees with authority to control foreign accounts may have personal filing obligations even when they do not own the funds.
• Waiting until tax season to evaluate foreign reporting obligations: Identifying foreign accounts and reporting requirements throughout the year makes compliance much easier than reconstructing records later.

10-Minute Foreign Account Reporting Self Check

• Does my company have a financial interest in any foreign financial account?
• Did the combined balance exceed $10,000 at any point during the year?
• Does any founder, officer, or employee have signature authority over a foreign account?
• Have I evaluated FBAR and Form 8938 separately?
• Does my company own foreign financial assets beyond bank accounts?
• Have I identified who may have personal filing obligations?

If several answers remain unclear, additional review may be worthwhile.

Bottom Line

International expansion often creates reporting obligations that founders do not anticipate. FBAR and FATCA serve different purposes, apply different rules, and may both apply to the same company or individual. Understanding these requirements before filing deadlines arrive can help startups avoid unnecessary penalties and establish stronger cross-border compliance practices.
