FBAR: Do You Need to Report Your Foreign Bank Accounts?

If you have authority over foreign accounts exceeding $10,000, the answer is yes. Here's what you need to know.

The FBAR (Report of Foreign Bank and Financial Accounts, FinCEN Form 114) is a reporting requirement for US persons who have financial interest in or signature authority over foreign financial accounts.

Who must file?

Any US person (citizen, resident, or entity) who had a financial interest in or signature authority over foreign financial accounts with an aggregate value exceeding $10,000 at any point during the year.

Wait — how does this affect international founders?

If you're a foreign person (non-US), FBAR generally doesn't apply to you personally. But:

Your US LLC may have an FBAR obligation if the LLC has interest in or authority over foreign bank accounts. For example, if your US LLC has a subsidiary or account in another country.

If you become a US tax resident (through the Substantial Presence Test or Green Card), then your personal foreign accounts become reportable.

What accounts are reportable?

  • Bank accounts (checking, savings)
  • Securities accounts (brokerage)
  • Mutual funds
  • Certain insurance policies with cash value
  • Pension accounts (in some cases)

The $10,000 threshold

The $10,000 is the aggregate maximum value of ALL foreign accounts combined, at any point during the year. If you have:

  • Account A peaked at $6,000
  • Account B peaked at $5,000
  • Combined peak: $11,000 → You must file

Even if the accounts never simultaneously held $10,000.

How to file

FBAR is filed electronically through FinCEN's BSA E-Filing System. It cannot be filed on paper.

Deadline: April 15, with an automatic extension to October 15. No form needed for the extension.

Penalties

FBAR penalties are severe:

  • Non-willful violation: Up to $12,500 per account per year
  • Willful violation: Up to $100,000 or 50% of the account balance, whichever is greater
  • Criminal penalties: Up to $250,000 fine and 5 years imprisonment

FBAR vs FATCA (Form 8938)

These are separate requirements:

  • FBAR → Filed with FinCEN, lower threshold ($10,000)
  • Form 8938 → Filed with IRS (attached to tax return), higher threshold ($50,000-$200,000 depending on filing status and residency)

You may need to file both.
