FBAR and FATCA: Complete Foreign Account Reporting Guide for US Persons

If you have a bank account, investment account, or retirement savings outside the United States, you likely have a legal obligation to report it to the IRS—and possibly to FinCEN as well. This guide cuts through the confusion between FBAR and FATCA, two separate but related reporting regimes that affect millions of US citizens and green-card holders living or working abroad, or maintaining foreign financial assets.

The Core Question: Do You Have to File?

Yes, if you are a US person (citizen, green-card holder, or resident alien) and you have a financial interest in, or signatory authority over, a foreign financial account with an aggregate balance exceeding the reporting threshold, you must file an FBAR. If that same account is held by a foreign financial institution, you may also have FATCA reporting obligations. Filing these reports correctly is non-negotiable—the penalties for non-compliance are severe, and the IRS has sophisticated information-sharing agreements with banks worldwide to catch unreported accounts.

What Is FBAR?

FBAR stands for Financial Crimes Enforcement Network (FinCEN) Form 114: Report of Foreign Bank and Financial Accounts. It is a distinct filing requirement, separate from your income tax return, administered by FinCEN (a bureau of the US Department of the Treasury) rather than the IRS itself.

Who Must File an FBAR?

You must file an FBAR if, at any time during the calendar year, you had a financial interest in or signature authority over a foreign financial account and the aggregate value of all such accounts exceeded the applicable threshold. According to FinCEN's official guidance, the current reporting threshold is $10,000 (though you should confirm the prevailing threshold for the year in which you are filing).

Key points:

FBAR Filing Deadline and Extensions

FBAR is filed annually using FinCEN Form 114. The deadline is April 15th, with an automatic extension to October 15th if you request it before the initial deadline. Unlike the income tax return, there is no need to file a separate extension form—you simply file the FBAR by the extended deadline.

What Is FATCA?

FATCA stands for the Foreign Account Tax Compliance Act (enacted in 2010). It is a reporting framework for US persons with foreign financial assets and a withholding regime for foreign financial institutions that do not comply with US information requests.

How FATCA Differs from FBAR

While both FBAR and FATCA may require you to report the same foreign accounts, they are separate obligations:

| Aspect | FBAR | FATCA |

|--------|------|-------|

| Administering Agency | FinCEN (Treasury) | IRS |

| Form | FinCEN Form 114 | Form 8938 (Schedule A to income tax return) |

| Reporting Threshold | $10,000 aggregate | Varies by filing status and residency; typically $100,000 for individuals |

| Types of Assets | Financial accounts | Broader: accounts, investments, retirement accounts, certain foreign partnerships |

| Filed With | FinCEN electronically | IRS with your income tax return |

| Penalty for Non-Filing | Up to $10,000 per violation (civil); criminal liability possible | Up to $10,000 per failure to file (civil); higher for fraud |

Who Must File Form 8938 (FATCA)?

You must file Form 8938 if you are a US person with specified foreign financial assets exceeding the applicable threshold. The IRS provides detailed eligibility rules on Form 8938 instructions, which depend on your filing status and whether you are a US resident or nonresident alien.

Generally:

When You Must File Both FBAR and Form 8938

Many US persons with foreign accounts will file both FBAR and Form 8938 in the same year, because the accounts are reportable under both regimes. This is not double-reporting in a punitive sense—it is the legal requirement. The good news is that the information you gather to complete one form largely carries over to the other.

Penalties for Non-Compliance

The IRS and FinCEN take foreign account reporting seriously. The IRS provides guidance on FBAR and FATCA penalties, and the consequences of non-filing are substantial:

The IRS uses offshore voluntary disclosure programs for taxpayers who wish to come into compliance, and these programs can mitigate penalties—but they require professional guidance and timely action.

Practical Steps to Ensure Compliance

1. Identify All Foreign Financial Accounts

Cast a wide net. Foreign accounts include:

2. Gather Account Information

Collect the following for each account:

3. Calculate Aggregate Value

Add up the maximum balance of all foreign accounts in US dollars (using the Treasury Department's exchange rate for the last day of the calendar year for FBAR; use a reasonable exchange rate for FATCA).

4. Determine Filing Obligations

If the aggregate value exceeds the FBAR threshold ($10,000), you file Form 114. If it exceeds the FATCA threshold (typically $100,000 for US residents), you file Form 8938 with your income tax return.

5. File Timely and Accurately

Special Situations

Expats and the Foreign Earned Income Exclusion

If you are a US citizen living and working abroad, you may be eligible to exclude a portion of your earned income from US taxation using the Foreign Earned Income Exclusion (FEIE). However, this exclusion does not eliminate your FBAR or FATCA obligations; you still must report foreign accounts, even if your income is excluded.

Married Couples Filing Jointly

Both spouses have a duty to report foreign accounts. If one spouse has sole control of an account, both are still required to include it in their aggregate calculation for FBAR purposes. Form 8938 has separate thresholds for married filing jointly couples (typically double the single threshold), but consult the current instructions.

Business Owners and Pass-Through Entities

If you own a foreign business, partnership, or corporation, the FATCA rules may require you to report the foreign financial accounts of that entity as well. This is a complex area; professional guidance is essential.

Common Mistakes to Avoid

The Role of Professional Guidance

FBAR and FATCA compliance is intricate, and the stakes—both financially and legally—are high. Every FBAR and Form 8938 filing reviewed by Next Tax Source is examined and signed by a licensed professional (CPA or Enrolled Agent in the US) to ensure accuracy and completeness. If you are uncertain about your obligations, or if you have unreported foreign accounts from prior years, seeking professional advice is not optional—it is prudent.

The IRS has vast data-sharing agreements with foreign tax authorities and financial institutions; unreported accounts are increasingly likely to be discovered. Proactive compliance—or, if necessary, voluntary disclosure—is far less costly than waiting for a notice of examination.

Frequently asked questions

Do I have to file FBAR if my foreign account balance never exceeds $10,000 in a single year?

No. The FBAR threshold is $10,000 in aggregate value at any time during the calendar year. If your account balances never reach that total, you are not required to file Form 114. However, if you cross the threshold at any point, you must file by the deadline.

I am a US citizen living in the UK. Do I file FBAR with the US or UK authorities?

FBAR is filed with FinCEN (US Treasury) only. The UK does not require a separate 'FBAR-equivalent' report, though the UK may have its own reporting rules for UK-sourced accounts. You have separate US and UK tax obligations; a licensed tax professional can advise on both.

What counts as a 'foreign financial account' for FBAR purposes?

Most accounts held outside the US count: bank accounts, investment accounts, retirement accounts (with exceptions), savings accounts, and money-market accounts. Notably, physical foreign real estate does not count, but a foreign bank account held in connection with rental property does. Consult a professional if you are unsure about a specific account.

If I already filed FBAR in prior years, do I need to amend old filings if I made a small error?

Small, non-material errors may not trigger penalties, but material errors (such as omitted accounts) can expose you to significant liability. If you discover an error, consult a tax professional about the best course of action—amending may be preferable to hoping the IRS does not notice.

Is there a voluntary disclosure program if I failed to file FBAR or FATCA forms in past years?

Yes. The IRS offers Offshore Voluntary Disclosure Practice (OVDP) and other programs for taxpayers seeking to come into compliance. These programs can reduce or eliminate penalties, but they require filing amended returns, paying back taxes, and interest. Acting promptly is important, as the IRS regularly updates its enforcement priorities.
