FBAR vs Form 8938: two reports, different rules, both can apply (US expat compliance guide)

FBAR (FinCEN 114) and Form 8938 (FATCA) are two different foreign-asset reports with overlapping but distinct rules. Many US expats file one and miss the other. Side-by-side comparison: thresholds, filing destinations, asset types, penalties, deadlines. Plus a checklist of who needs what.

TL;DR

FBAR (FinCEN Form 114) — filed to FinCEN (Treasury), not the IRS. Triggered by $10,000 aggregate in foreign financial accounts at any point during the year. Penalty: $16,536 non-willful or greater of $165,353/50% balance willful per year per account.

Form 8938 (FATCA Statement of Foreign Financial Assets) — filed with your 1040 to the IRS. Higher thresholds, scales with filing status and residence. Penalty: $10,000 initial + up to $50,000 continuation.

Both can apply to the same person — they're not alternatives. Each has its own rules and you may owe both.

FBAR covers more: any foreign account where you have signature authority (even employer accounts, family-member accounts you can sign on).

Form 8938 covers different things: includes foreign-issued securities, interests in foreign entities, foreign pension plans — beyond just bank accounts.

Willful penalty	Greater of $165,353 or 50% of account balance per year	$10,000 + up to $50,000 (lower than FBAR)
Statute of limitations	6 years	3 years (6 if you omit more than $5K of unreported foreign-asset income)

Who needs FBAR

Any US person (citizen, resident, Green Card holder, US entity) with financial interest in or signature authority over foreign financial accounts whose aggregate value exceeded $10,000 at any point during the calendar year.

"Financial interest" means ownership. "Signature authority" means you can direct disposition of assets even if you don't own them.

This catches:

The savings account you kept open in your home country with $11,000 in it.

Your foreign employer's account you have signing rights on for business expenses.

Your mother's account in Russia where you're listed as a backup signer.

The crypto exchange account at Binance, Kraken EU, etc. (if it holds fiat or crypto convertible to fiat).

The foreign brokerage account at Interactive Brokers UK, Saxo Bank Denmark.

Aggregate test: not per-account. If you have €4,000 in a German account + €4,000 in a Spanish account + €3,000 in a French account = €11,000 ≈ $11,800. FBAR required.

Who needs Form 8938

Any specified person with foreign financial assets above the threshold. Specified person = individual US person (including dual-status alien), or certain US trusts/entities.

Thresholds depend on filing status + residence:

Filing status	Living in US (end of year balance / any-day)	Living abroad (end of year / any-day)
Single, HoH, QSS	$50K / $75K	$200K / $300K
MFJ	$100K / $150K	$400K / $600K
MFS	$50K / $75K	$200K / $300K

"Living abroad" = US citizen/resident who is bona fide resident of foreign country for entire year OR physically present 330+ days in foreign country.

Both can apply

It's common to owe both forms for the same accounts:

Example: US citizen living in Spain. Has €250K (~$275K) in Spanish savings + brokerage accounts.

FBAR threshold $10K? Easily exceeded. Must file FBAR.

Form 8938 threshold for single US person abroad = $200K end of year. Exceeded. Must file 8938.

Filing one doesn't excuse you from the other. Both must be filed.

Reverse situation: US person in the US with $40K in foreign accounts.

FBAR threshold $10K? Yes. File FBAR.

Form 8938 threshold for single US resident = $50K end of year / $75K any day. $40K < $50K. No Form 8938 required.

What FBAR covers that Form 8938 doesn't

Signature authority without financial interest — Form 8938 only covers assets you own. FBAR covers accounts you can sign on even without ownership.

Certain insurance policies — life insurance with cash value held abroad: FBAR yes, Form 8938 yes but rules differ.

Foreign mutual fund accounts — FBAR yes (it's an account); Form 8938 yes (it's a specified asset).

What Form 8938 covers that FBAR doesn't

Foreign stock or securities held outside a financial account — e.g., shares of a foreign private company held in your name. FBAR no (not an account); Form 8938 yes (specified foreign asset).

Interest in a foreign partnership or trust — Form 8938 yes. FBAR no.

Foreign-issued life insurance with cash value, even without an account custodian — Form 8938 yes.

Foreign retirement accounts — Form 8938 yes (in most cases); FBAR yes (most foreign pensions are accounts).

Penalty stakes

FBAR

Non-willful: $16,536 per violation per year (2024 inflation-adjusted, climbing).

Willful: greater of $165,353 OR 50% of account balance, per year. Criminal prosecution possible.

Multiple accounts = multiple potential violations.

Form 8938

Initial failure to file: $10,000.

Continued failure after IRS notice: $10,000 per 30-day period (max additional $50,000).

Reasonable cause can defeat the penalty if documented.

FBAR penalties are vastly higher than Form 8938 penalties. The IRS has more flexibility on 8938 abatement than on FBAR.

Checklist: who needs what

You need FBAR if:

US person (citizen, GC holder, US resident, US entity)

Any combination of foreign financial accounts aggregated above $10K at any moment in the year

Including accounts you don't own but can sign on

You need Form 8938 if:

Same person definition

Specified foreign financial assets above the threshold for your status/residence

Includes assets beyond accounts (stocks, private equity, partnership interests)

You typically need both if:

US expat abroad with > $200K specified foreign financial assets

US resident with > $50K specified foreign financial assets

You only need FBAR if:

Low foreign asset balance ($10K-$50K range as US resident) — above FBAR threshold but below 8938

What to do if you've never filed either

Use the Streamlined Filing Compliance Procedures: catch up on 6 years of FBAR + 3 years of 8938 with the rest of your return amendments. Zero penalty under SFOP (if you live abroad) or 5% miscellaneous offshore penalty under SDOP (if you live in the US).
