US Expat Tax Penalties that hit US Citizens and Resident Aliens may be required to file US income tax returns and other forms, noncompliance could result in substantial penalties.

FBAR Penalties (FinCEN Form 114)
The #1 penalty risk for expats – the majority of Expats will have an FBAR (reporting of ownership or signatory authority over non-US financial accounts) filing requirement. Although these US Expat Tax Penalties are not as commonly assessed as other International Forms Penalties, the risk of assessment is real.
Triggered by:
- Foreign bank accounts totaling over $10,000 at any time during the year
- Applies even if accounts earn no income
Penalty amounts
- Non-willful: up to $10,000 per year
- Willful: greater of $100,000 or 50% of the account balance
- Can be assessed per year, per account
Why expats get hit:
- FBAR is not an IRS form (filed separately)
- No tax owed ≠ no filing requirement
FATCA Penalties (Form 8938)
This is another reporting of non-US financial accounts that is required if the filing requirements are met.
Triggered by:
- Foreign financial assets above:
- $200,000 (single, living abroad, end of year)
- $300,000 (married filing jointly)
Penalty amounts
- $10,000 for failure to file
- Additional $10,000 every 30 days after IRS notice
- Maximum: $60,000 per year
Common mistake:
- Assuming FBAR replaces Form 8938 (it does not)
Foreign Trust Penalties (Forms 3520 & 3520-A)
The IRS has been known to assess these penalties automatically and they are one of the most challenging penalties to get waiver on. US Expat Tax Penalties on these forms are usually administered by the international tax department of the IRS.
Most severe “paperwork” penalties
Triggered by:
- Foreign pensions
- Non-US retirement plans
- Education savings plans
- Foreign life insurance with cash value
- Gifts or inheritances from non-US persons
Penalty amounts
- Form 3520: greater of $10,000 or 35% of:
- Contributions
- Distributions
- Gifts
- Form 3520-A: 5% of trust assets per year
Why expats get hit:
- Many foreign pensions are treated as foreign trusts
- Penalties apply even when fully taxed
PFIC Penalties (Form 8621)
Although these are not monetary US expat tax penalties, they can still be costly as the statute of limitations never closes on the returns filed that are missing these filings.
Triggered by:
- Non-US mutual funds
- ETFs
- Foreign investment funds
Penalty structure
- No fixed penalty
- IRS can:
- Impose punitive tax rates
- Add interest going back years
- Statute of limitations never closes if missing
Common expat mistake:
- Buying local mutual funds in country of residence
Late or Missing US Tax Return (Form 1040)
Filing a tax return with the IRS, effectively closes the loop for that year as far as the IRS is concerned, they have the filing that shows income was earned and no tax due was payable or the tax due was paid. If a return is not filed for a tax year, there is no information in the IRS database regarding the year, if information is received later that shows that a tax return was due and not filed, it could result in notices or a substitute tax return being filed by the IRS on your behalf. This could result in US Expat Tax Penalties.
Even if no tax is owed:
Penalties
- Failure to file: up to 25%
- Failure to pay: up to 25%
- Interest always applies
Important expat rule:
- Automatic 2-month filing extension (to June 15)
- No extension to pay
Currency & Reporting Errors
Triggered by:
- Not converting foreign income to USD
- Incorrect exchange rates
- Missing foreign income entirely
Penalty exposure
- Accuracy-related penalty: 20% of underpaid tax
- Higher if IRS asserts negligence
Business & Self-Employed Expats
Common US Expat tax penalties
- Underpayment of estimated taxes
- Failure to file:
- Form 5471 (foreign corporation)
- Form 8865 (foreign partnership)
Penalty amounts
- $10,000 per form, per year
- Additional penalties if uncorrected
Penalty Stacking (Most Dangerous)
Expats often face multiple penalties for the same account:
Example:
- FBAR penalty
- FATCA penalty
- 3520 penalty
- Accuracy penalty
➡ One account can trigger six-figure exposure
