FBAR and FATCA Explained: Reporting Your Foreign Bank Accounts Without Penalties

Your ordinary overseas bank account can trigger a US filing obligation before you think of it as a significant asset. As a US citizen, you generally remain subject to US tax on worldwide income, and account reporting adds a separate compliance task. ¹

This is general information. Your CPA and counsel confirm the details for your case.

The aim is to identify the accounts, apply the right tests and meet the relevant deadlines. If an account or an earlier year is missing, deal with the correction route before repeating the omission on another filing.

FBAR starts with your aggregate accounts

Under the FBAR rules, a US person must file an FBAR when they have a financial interest in, or signature or other authority over, a foreign financial account and aggregate foreign-account value exceeded $10,000 at any time in the calendar year. The rule reaches US citizens and residents as well as specified entities. ²

The threshold is cumulative. If two accounts together exceed $10,000 at any one time, both must be reported. Looking only at an individual account's balance can therefore miss the reporting trigger. Review the complete account list, including accounts over which you have authority. Include the account you rarely use as well as the one used for daily spending. ³

Don't remove an account from the list simply because you think it belongs to a different reporting category. Give your adviser the facts first and let the review establish whether an exception applies. Your working list and your final filing don't need to be identical; the list should make omissions harder.

FBAR has its own submission route

The FBAR rules give an April 15 deadline following the calendar year, with an automatic extension to October 15 that doesn't require a request. You file FinCEN Form 114 electronically through the BSA E-Filing System. It doesn't go inside your income-tax return. Record that filing as its own task and keep its confirmation separately. ²

FBAR records generally need to be kept for five years from the due date. The required records include the name on the account, account number, bank name and address, account type and maximum value. Use those fields to organize the documents you request from each institution. A folder of statements is more useful when you can connect every account to those details. ²

FATCA reporting uses a different form and test

Form 8938 is attached to your income-tax return. The IRS comparison gives thresholds for taxpayers living abroad of more than $200,000 at year-end or $300,000 at any time for single or married-filing-separately taxpayers. For joint filers abroad, those figures are more than $400,000 and $600,000. Confirm that you meet the applicable abroad category before using those higher thresholds. ³

Filing Form 8938 doesn't replace the FBAR. The IRS comparison lists a failure-to-disclose penalty of up to $10,000, followed by $10,000 for each thirty days of continued non-filing after IRS notice, for a potential maximum of $60,000. Criminal penalties may also apply. These are published consequences, not a prediction of what would happen in your case. ³

Read published FBAR penalties carefully

FinCEN's published 2025 inflation-adjusted maximum civil penalty figures are $16,536 for a non-willful FBAR violation and $165,353 for a willful violation. The April 2026 OMB memorandum cancelled the 2026 inflation adjustment, leaving agencies using the 2025 levels. Those are the published dollar figures carried into 2026. ^{4, 5}

Don't treat that pair of numbers as a complete calculation of possible liability. Willful-penalty exposure also involves statutory balance-based rules. The published dollar figures alone don't establish a ceiling for your case. An enforcement or conduct question needs a qualified tax lawyer's review before you submit a correction.

The Supreme Court's February 2023 Bittner decision held that the non-willful penalty accrues per report, not per account. Keep that distinction separate from the obligation to report all relevant accounts. A rule about how a penalty is counted doesn't remove the underlying reporting requirement. ⁶

What this means for you

An ordinary banking decision can create two distinct reporting tasks. Keep one complete account inventory, then identify the FBAR and Form 8938 obligations separately. Your banking plan becomes easier to manage when every account has an owner, a reporting decision and a filing record.

What to do this month

• Request the records needed to establish account maximum values, and check the ownership and signing-authority details against your full list of overseas accounts.
• Assign FBAR and Form 8938 as separate tasks. Record the filing route and confirmation for each instead of treating your income-tax submission as proof both are done.
• Create a retention folder using the FBAR record fields. Make account numbers, institution details and the reporting year easy to locate without searching every statement.
• If an earlier year is missing, prepare a factual chronology of the omission and any official contact. Get the correction route settled before submitting an incomplete response.

Common mistakes to avoid

• Testing the $10,000 FBAR threshold account by account.
• Assuming your income-tax return includes the FBAR submission.
• Treating Form 8938 as a replacement for the FBAR.
• Reading published maximum penalties as a personalized assessment.

The FNC angle

Banking access and reporting readiness should be discussed together. When you explore another account or a business structure with FNC, include the ownership and authority details your CPA will need. The question is how the account serves your life or business and how you'll document it. Opening an account should leave you with a clear reporting question to resolve, rather than a new account that disappears from your annual review.
