FBAR and FATCA for ITIN Holders With Foreign Accounts: The $10,000 Rule and Form 8938
Once you become a US tax resident — through green card, H-1B substantial presence, or any other path — your foreign bank accounts, brokerage accounts, and certain investments become US-reportable. A walkthrough of when FBAR (FinCEN 114) and Form 8938 are required, the $10,000 / $50,000 thresholds, the $10,000-per-account penalties, and the strategies to simplify reporting.
The Reporting Obligation Nobody Sees Coming
You're an H-1B holder from Shanghai. You've been in the US for two years, just became a US tax resident via Substantial Presence Test. You still have a Bank of China savings account with $25,000 in it — money from before you moved. You have a brokerage account in Hong Kong with $60,000 worth of Apple stock you bought before the move. You haven't touched either, don't send money to them, just let them sit.
You file your US 1040 dutifully. No US tax issues.
Eighteen months later, a letter arrives: civil penalty for failure to file FBAR, civil penalty for failure to file Form 8938, proposed assessment of $10,000 per account per year. The total bill could be $40,000-$80,000 depending on how the IRS applies the penalty framework.
You didn't hide anything. You didn't even use the accounts. But the moment you became a US tax resident, your foreign financial accounts became US-reportable. The rules that require reporting are FBAR (FinCEN 114) and FATCA (Form 8938), and they operate independently with overlapping but not identical thresholds.
This guide walks through exactly what must be reported, when, to whom, and how to handle the compliance gracefully — especially for the common scenario of recently-arrived non-residents-turned-residents who had pre-existing foreign accounts.
Two Separate Reporting Regimes
FBAR (FinCEN Form 114)
- Administered by: Treasury's Financial Crimes Enforcement Network (FinCEN)
- Threshold: $10,000 aggregate across all foreign financial accounts at any point during the year
- Who must file: US persons (citizens, residents, green card holders, and certain entities)
- Filed separately from income tax return: electronically via BSA E-Filing System
- Due date: April 15 (same as tax return) with automatic extension to October 15
FATCA (Form 8938 - Statement of Specified Foreign Financial Assets)
- Administered by: IRS as part of the income tax return
- Threshold: $50,000-$200,000 depending on filing status (higher for residents overseas)
- Who must file: US persons with specified foreign financial assets exceeding threshold
- Filed with Form 1040: attached to the annual tax return
- Due date: April 15 with extensions
The two filings cover overlapping but distinct universes of accounts:
- FBAR covers bank, brokerage, and other financial accounts
- Form 8938 covers FBAR-type accounts PLUS certain other foreign financial assets (non-US partnerships, non-US mutual funds, non-US hedge funds, etc.)
In practice: if you have foreign accounts, you likely need to file both. Failing one doesn't fulfill the other.
Who Must File FBAR
You must file an FBAR if all of these apply:
1. You are a US person — citizen, resident alien (green card or SPT), or certain entities
2. You had a financial interest in or signature authority over foreign financial accounts
3. The aggregate value of those accounts exceeded $10,000 at any point during the calendar year
Key point: $10,000 aggregate, not per account. A $4,000 bank account + a $7,000 brokerage account = $11,000 aggregate → FBAR required, and both accounts must be reported.
What Counts as "Financial Interest"
You have a financial interest in an account if:
- You are the owner of record
- You are the beneficial owner (e.g., nominee arrangement)
- You own more than 50% of an entity (corp, LLC, partnership) that owns the account
- You are a beneficiary of a trust that owns the account
What Counts as "Signature Authority"
You have signature authority if you can control how funds are disbursed, regardless of whether you have an ownership interest. Example: a Chinese employee who has signature authority on a company account back home triggers FBAR reporting even if the company is not theirs.
What Counts as a "Financial Account"
- Bank accounts (checking, savings, time deposits, fixed deposits)
- Securities/brokerage accounts
- Mutual fund accounts
- Life insurance or annuity policies with a cash value
- Retirement or pension accounts with a balance
- Cryptocurrency held on foreign exchanges (still evolving; be cautious)
What does NOT count:
- Real estate (not a financial account — reported elsewhere if at all)
- Direct ownership of shares in a publicly traded company (not via brokerage)
- Precious metals stored at home (not a financial account)
What Accounts Are "Foreign"
An account is foreign if the custodian or institution is physically located outside the US. A New York Chase branch is US; a Hong Kong HSBC branch is foreign. The geographic location of the institution controls, not the currency or residence of the holder.
Who Must File Form 8938 (FATCA)
You must file Form 8938 if you are a specified person AND your specified foreign financial assets exceed the threshold at the end of the year OR at any point during the year.
Specified Person
- US citizen
- US resident alien (green card or SPT passed)
- Certain non-residents filing jointly with a US spouse
Non-resident aliens who file only 1040-NR (not 1040) do NOT file 8938.
Thresholds (2026 — Single/HOH Unless Noted)
| Location of Specified Person | End of Year | Any Point in Year |
|---|
| US residents (single) | $50,000 | $75,000 |
| US residents (married filing jointly) | $100,000 | $150,000 |
| Expats abroad (single) | $200,000 | $300,000 |
| Expats abroad (married filing jointly) | $400,000 | $600,000 |
Important: these thresholds are end-of-year OR any-point-during-year. If your account temporarily spiked to $80,000 in March (say a big stock gain or currency swing) and ended the year at $40,000, you still file 8938 because the "any point during year" threshold was crossed.
Specified Foreign Financial Assets
FBAR-reportable accounts AND:
- Foreign partnership interests (even if the partnership is the one with US filings)
- Foreign mutual funds, private funds, hedge funds
- Stock in a foreign corporation you hold directly (not via brokerage)
- Foreign retirement plans (if not social security)
- Foreign notes, bonds, debentures (directly held)
The Numbers That Really Matter: Penalties
FBAR Non-Willful Penalty
Even if you didn't know the requirement existed:
- Civil penalty: up to $10,000 per unreported account, per year
- After IRS guidance in 2024, this is generally capped at "per account" rather than "per violation per account," but earlier interpretations applied per year
- Could easily reach $50,000-$100,000 for a multi-account, multi-year oversight
FBAR Willful Penalty
If the IRS determines you willfully failed to file:
- Civil penalty: up to greater of $100,000 or 50% of the account balance at the violation
- Criminal penalty potentially applicable in egregious cases
Form 8938 Penalty
- $10,000 for failure to file
- $50,000 continuing penalty if not filed after IRS notice
- Accuracy-related penalty of 40% on any undisclosed foreign asset income
Cumulative Impact
For a resident alien with 2 foreign accounts totaling $75,000, not filed for 3 years:
- FBAR non-willful penalty: up to $10,000 × 2 × 3 = $60,000
- Form 8938 penalty: up to $10,000 × 3 = $30,000
- Total potential: $90,000
This is why compliance is non-negotiable.
When Does the Obligation Start
This is the subtle part that catches newly-arrived non-residents.
You become a US tax resident the moment you:
- Get a green card (first day of the year you hold it)
- Pass the Substantial Presence Test (~183-day formula)
- Elect first-year choice
The FBAR and Form 8938 obligations begin in your first year as a US tax resident. Pre-existing accounts don't grandfather in. Your accounts that were fine when you were abroad become reportable the moment you cross the residency threshold.
Example: H-1B Arrival Timing
- Arrived in US: August 15, 2026
- Substantial Presence passed: around February 2027 (after 183 days in US)
- First year as US resident: 2026 (dual-status, but resident portion includes accounts owned)
- FBAR for tax year 2026 due: April 15, 2027
- Account existed since 2020 in your home country
The 2026 FBAR must include all foreign accounts — even though most of the year you were a non-resident. You were a US resident for the last 4.5 months of 2026, but FBAR filing is required when you are a US resident at year-end.
Practical Filing Mechanics
Filing FBAR
FBAR is filed electronically through the BSA E-Filing System at bsaefiling.fincen.treas.gov.
Process:
1. Register for an account (first-time users)
2. Fill in FinCEN Form 114 online
3. For each account: institution name, country, account number, maximum value during the year
4. Submit electronically
5. Keep confirmation email
You do NOT mail FBAR. It is electronic-only. A paper version exists but is for your records, not submission.
Filing Form 8938
Form 8938 is attached to your Form 1040 when you file your tax return. It is a multi-page form that lists each specified foreign financial asset with opening balance, closing balance, maximum value during the year, and any income generated.
Most tax software handles Form 8938 automatically if you answer the right questions during the interview.
Translating Account Balances to USD
For both FBAR and Form 8938, amounts are reported in USD using the US Treasury's end-of-year exchange rate (or the rate in effect when the maximum value occurred for FBAR purposes).
You can find current and historical rates at fiscal.treasury.gov.
Correcting Past Non-Filings
If you discover you should have been filing FBAR or Form 8938 in prior years and haven't, you have several paths:
Streamlined Filing Compliance Procedures
For US residents who non-willfully failed to file:
- File amended returns for up to 3 years (or 6 for certain cases)
- File delinquent FBARs for up to 6 years
- Pay any additional tax owed plus a 5% "Title 26 miscellaneous offshore penalty" on the highest aggregate account balance over the 6-year period
- Penalty waived entirely if you can establish non-willful conduct AND meet other criteria
Voluntary Disclosure Practice
For willful violations or potential criminal exposure:
- Through IRS Criminal Investigation Voluntary Disclosure Program
- Much higher penalties (typically 50% of the highest aggregate balance)
- But provides protection from criminal prosecution
Delinquent FBAR Submission Procedure
If you have foreign income that WAS reported on the tax return but FBAR was missed:
- Simple late-file the FBAR with a short reasonable-cause letter
- Often no penalty if the underlying income was properly reported
Delinquent 8938 Submission Procedure
If 8938 was missed but the income was reported:
- Attach to an amended return explaining the late filing
- Usually no penalty if the underlying income was properly reported
Do not just start filing going forward without addressing the past. The IRS compares current-year filings against prior-year omissions.
Common Situations for ITIN → SSN Transitioners
Situation 1: Accumulated Savings in Home Country Bank Account
- Account held for years before moving to US
- Becomes reportable the year you become US tax resident
- FBAR required if aggregate with other accounts exceeds $10,000
- 8938 required if thresholds crossed
- No US tax on balance itself, but interest earned is US-taxable as worldwide income
Situation 2: Home-Country Retirement Account
- Many home-country retirement accounts (e.g., China 个人养老金 / 公积金, UK ISA, India EPF, Japan iDeCo) are US-reportable
- US pension/401(k)-equivalent treatment under treaty may defer tax, but reporting is still required
- FBAR: reportable
- 8938: reportable
- US tax: depends on the specific account type and treaty; some accrue US tax currency even without distribution
Situation 3: Brokerage Account Holding Stocks/ETFs
- Brokerage accounts at foreign institutions are reportable
- The stocks/ETFs themselves may trigger additional reporting if they are Passive Foreign Investment Companies (PFICs) — most non-US ETFs and non-US mutual funds are PFICs
- PFIC treatment is extremely unfavorable — mark-to-market or QEF election required or else punitive excess distribution treatment
Situation 4: Jointly-Held Account with Non-US Spouse
- If you have signature authority on an account in your spouse's name, FBAR applies
- If you are a joint owner, the full balance is yours for FBAR threshold purposes
- Spouse's solo accounts that you have no interest or signature authority in: not your FBAR
Situation 5: Foreign LLC Owned by You
- If the LLC's accounts are foreign, and you own 50%+, FBAR applies to the LLC's accounts
- Form 5471 may also apply (for US owners of foreign corporations)
- This is a complex area; consult a cross-border CPA
Strategies to Simplify Reporting
Strategy 1: Consolidate Before Moving
If you know you'll be moving to the US:
- Close unnecessary foreign accounts before becoming a US resident
- Keep one primary account in your home country for family/travel needs
- Move investments to US accounts after arrival where possible
Strategy 2: Keep Balances Below Thresholds Where Practical
If you only have one foreign account and it's below $10,000, no FBAR. Below $50,000 (single) or $100,000 (married), no Form 8938.
This isn't always practical — balances may exceed thresholds naturally. But conscious management can reduce complexity.
Strategy 3: Use Tax Software That Handles Both
TurboTax Premier, H&R Block Premium, TaxAct, and others support both FBAR and Form 8938 in their worldwide-income versions. The software asks about foreign accounts during the interview and generates both filings correctly.
Strategy 4: Work with a Cross-Border CPA
For first-year US residency transition, or complex situations (foreign retirement accounts, PFICs, foreign partnerships), a cross-border CPA is worth the ~$500-$2,000 fee. The penalty cost of mistakes is much higher.
See How to Find a Cross-Border Tax Professional.
The Non-Resident Exception
If you remain a non-resident (file 1040-NR, not 1040), neither FBAR nor Form 8938 applies to your foreign accounts. The obligation is tied to US tax residency.
A non-resident with a Wyoming LLC: the LLC is a US entity and its US accounts aren't "foreign." The non-resident owner's personal foreign accounts are not US-reportable because the owner isn't a US person.
This changes the moment the owner becomes a US tax resident.
Currency and Cryptocurrency Wrinkles
Currency Conversion Timing
For FBAR: use the Treasury rate on the date of maximum value.
For Form 8938: use the year-end rate, or if not held at year-end, the rate on the last day of holding.
These rates are published at fiscal.treasury.gov.
Cryptocurrency Held on Foreign Exchanges
- Recent guidance from FinCEN and IRS: crypto held on foreign-centralized exchanges is generally reportable on FBAR
- Self-custody wallets with keys held personally: currently no FBAR required for the wallet itself
- Crypto held on foreign crypto-brokerage (exchange-as-custodian): FBAR required
This is an evolving area; check current guidance.
The Compliance Calendar
October (of the year before filing year): If you're about to become a US resident, make a list of all foreign accounts with values.
January-March (year of US residency): Download all prior-year statements for foreign accounts.
April 15 (after year-end): File Form 1040 with Form 8938 attached. File FBAR on BSA system.
October 15: Automatic extended deadline for both.
For first-time filers, budget 4-8 hours for research, documentation, and filing. For subsequent years, routine maintenance is much faster — maybe 2 hours.
Summary
- FBAR applies if aggregate foreign financial accounts exceed $10,000 at any point in the year
- Form 8938 applies at higher thresholds ($50k/$100k for residents; $200k/$400k for expats)
- Both are independently required; filing one doesn't satisfy the other
- Penalties start at $10,000 per account/year and can reach $100k+
- Your obligations begin the moment you become US tax resident
- Pre-existing accounts are not grandfathered
- Correct past non-filings via Streamlined Procedures if non-willful
- ITIN holders who remain non-residents (file 1040-NR only) do NOT file FBAR/8938
- Consolidate and simplify accounts before residency transition when possible
The FBAR/FATCA rules are among the most penalty-heavy in the US tax system — much more so than most income-tax issues. For non-residents transitioning to US tax resident status (via H-1B, green card, or SPT), setting up the compliance process in Year 1 is essential to avoiding five- or six-figure penalty exposure.
