FBAR and FATCA Reporting

FBAR and FATCA reporting applies to US persons resident in Japan who hold financial accounts or assets outside the United States.¹² The two filings run on separate tracks, so a Japan-resident filer can owe one, both, or neither in a given year.³

Confirm current details with official sources

Procedures, fees, and requirements can change. Confirm current details at the Financial Crimes Enforcement Network site and the Internal Revenue Service site. This article is general information, not legal, tax, or immigration advice; for your specific case, consult a licensed US tax professional (CPA or enrolled agent) experienced in cross-border filings, and a Japanese 税理士 (zeirishi, "licensed tax accountant") for Japan-side tax questions.

Overview

FBAR is the Report of Foreign Bank and Financial Accounts on FinCEN Form 114, administered under the Bank Secrecy Act.¹⁴ FATCA individual reporting is the Statement of Specified Foreign Financial Assets on IRS Form 8938, attached to the annual income tax return.²⁵

This article covers US citizens, green-card holders, and other US persons living in Japan. It does not cover non-US residents, whose home-country reporting follows different rules.

The practical split is simple. FBAR asks where your foreign accounts sit and whether their combined peak crossed $10,000.⁴ Form 8938 asks whether your specified foreign financial assets crossed a much higher living-abroad threshold.²

FBAR: Who Must File and What Counts

A US person files an FBAR where the person has a financial interest in, or signature or other authority over, at least one financial account located outside the United States.¹⁴ The 金融犯罪取締ネットワーク (kin'yū hanzai torishimari nettowāku, "Financial Crimes Enforcement Network"), known as FinCEN, receives the report through its BSA E-Filing System.¹

A US person includes citizens, residents, and domestic entities such as corporations, partnerships, LLCs, trusts, and estates.⁴ Living in Japan does not remove that status.

The $10,000 aggregate rule

The trigger is aggregate value exceeding $10,000 at any time during the calendar year.¹⁴ The test is cumulative across all foreign accounts, not per account, and it keys to the peak balance, not the year-end balance.⁴³

Whether an account produced taxable income has no effect on whether it counts.⁴ A zero-interest savings balance still counts toward the aggregate.

Signature authority alone can trigger the obligation even without a financial interest.³ Authority here means the power to control disposition of account assets by direct communication with the institution holding the account.³

Which Japan-held accounts fall in scope

Generally, an account at a financial institution located outside the United States is a foreign financial account.⁴ For a Japan-resident US person, ordinary Japan-based bank and securities accounts sit in scope.

Category	FBAR treatment	Notes
Japan bank deposits (checking, savings, time deposits)	Reportable4	Includes accounts at banks physically located in Japan
Japan securities or brokerage accounts	Reportable4	Report the account, not each holding separately3
Foreign mutual funds held in Japan	Reportable43	Account-level reporting
Cash-value life insurance or annuities issued abroad	Reportable43	Cash surrender value, per comparison-table framing
Foreign pension or deferred-compensation interests in accounts	Reportable6	See Form 8938 section for the parallel treatment
Account at a foreign branch of a US bank	Reportable3	Foreign location controls
Account at a US branch of a foreign bank	Not reportable3	US location controls

Excluded categories include correspondent and nostro accounts, accounts owned by a governmental entity or an international financial institution, and accounts maintained on a US military banking facility.⁴ IRA accounts of which the filer is owner or beneficiary are excluded, as are retirement-plan accounts of which the filer is participant or beneficiary, plus trust-beneficiary accounts covered by a US-person consolidated report.⁴

Two narrow excuses remove the filing duty. All accounts reported on a consolidated FBAR need no separate filing.⁴ Joint spousal accounts need no separate filing where the spouse timely reports them with a signed Form 114a authorization kept on record.⁴ Income-tax filing status does not affect that spousal exception.⁴

Check Japan product names against US categories

Japan-side product labels do not map one to one onto US reporting categories. Confirm each account against the institution-location and account-type rules above, and raise unclear products with a cross-border tax professional rather than assuming an exclusion.

FATCA Form 8938: Thresholds and Scope

Form 8938 reports specified foreign financial assets to the Internal Revenue Service as part of the annual return.²⁵ The living-abroad thresholds below apply where the taxpayer must file an income tax return, holds a foreign tax home, and meets a presence-abroad test.²⁵

The presence test has two alternative paths. One is bona fide residence in a foreign country for an uninterrupted period that includes the entire tax year.²⁵ The other is presence in a foreign country or countries for at least 330 full days during a 12-month period ending in the tax year.²⁵

A taxpayer who must file uses the higher living-abroad bands only where both the foreign tax home and a presence path are met. A filer who fails that test uses the lower US-side bands instead.²⁵

Living-abroad thresholds by filing status

The figures in this section move only when the Internal Revenue Service revises its guidance (as of 2026-09; confirm current figures with the Internal Revenue Service).²⁵

Filer	Year-end test	Any-time test	As of
Not filing jointly (single and comparable cases)	More than $200,000 on the last day of the tax year2	More than $300,000 at any time during the year (as of 2026-09)2	2026-092
Married filing jointly	More than $400,000 on the last day of the tax year (as of 2026-09)2	More than $600,000 at any time during the year (as of 2026-09)2	2026-092

Joint filers submit a single Form 8938 covering the specified assets of either spouse, and the joint thresholds apply even where only one spouse resides abroad (as of 2026-09).²⁵ By contrast, the US-side bands are $50,000 year-end or $75,000 any-time for single filers and $100,000 year-end or $150,000 any-time for joint filers (as of 2026-09); those bands do not apply to a qualifying Japan-resident filer.²³

A taxpayer not required to file an income tax return for the year files no Form 8938 regardless of asset value.⁵⁶

What counts as a specified foreign financial asset

Specified assets comprise financial accounts maintained by a foreign financial institution plus certain non-account assets held for investment.²⁵ Non-account examples include foreign stock and securities, foreign financial instruments, contracts with non-US persons, and interests in foreign entities.²

Asset	Form 8938 treatment
Financial account at a foreign financial institution	Reportable, even where contents include US-issued assets; report the account once6
Foreign stock or securities held outside an account	Reportable6
Foreign stock or securities held inside a reported account	Not separately reported6
Foreign partnership interests	Reportable5
Foreign hedge and private-equity fund interests	Reportable3
Foreign pension or deferred-compensation interest	Reportable6
Foreign-issued life insurance or annuity with cash value	Reportable3
Account at a US branch of a foreign institution (US payor)	Not reportable2
Directly held foreign currency, foreign real estate, precious metals, or personal property	Not reportable6
Foreign-equivalent Social Security or social-insurance rights	Not reportable26

Real estate held through a foreign entity is handled at the entity level. The entity interest is the reportable asset, with the real-estate value feeding the entity-interest value, while the property itself is not separately listed.⁶

Assets already detailed on Forms 3520, 3520-A, 5471, 8621, 8865, or 8891 are identified on Form 8938 Part IV rather than detailed twice.² Their value still counts toward the threshold for specified individuals.²

Values convert to dollars at the Treasury Bureau of the Fiscal Service year-end rate, or another public rate where Treasury publishes none, measured at the last day of the tax year (as of 2026-09).² Account statements may support account maximums, while other assets may rest on public or verifiable sources or a reasonable estimate where none exists.²

Convert yen values at the year-end Treasury rate

Build each yen maximum first, then convert at the Treasury year-end rate for the tax year. Using a mid-year or card-provider rate changes the threshold math.²

Filing Both: How FBAR and Form 8938 Relate

Filing Form 8938 never satisfies an FBAR duty, and filing an FBAR never satisfies a Form 8938 duty.²³ The forms use different definitions (including different meanings of "financial account") and different thresholds, so an account can appear on one form but not the other.²³ Non-account investment assets appear only on Form 8938.²

The decision logic below summarizes the dual track for a Japan-resident US person.

Where and when each form is filed

FBAR goes electronically through FinCEN's BSA E-Filing System, never inside the federal tax return.¹⁴ Paper filing needs a FinCEN Resource Center exemption, and the Internal Revenue Service does not accept obsolete TD F 90-22.1 or printed FinCEN Form 114.⁴

A third party files an FBAR for the filer only with a Form 114a authorization kept on record rather than submitted with the report.⁴ For each reported account the filer retains the account name, account number, foreign bank name and address, account type, and maximum value during the year.⁴

FBAR is an annual report due April 15 following the calendar year, with an automatic extension to October 15 that needs no request.⁴ Form 8938 attaches to the annual return and is due on that return's due date including extensions.⁵³

One filing never covers the other obligation

The same Japan accounts can appear on both forms where both thresholds are met. Check each form separately every year, because the recipients, definitions, and deadlines differ.²³

Penalties and reasonable cause

FBAR violations can draw civil monetary penalties and criminal penalties depending on facts and circumstances.⁴ Stated Title 31 maximums adjust annually for inflation.⁴

The Internal Revenue Service comparison baseline states non-willful FBAR violations up to $10,000 and willful violations up to the greater of $100,000 or 50 percent of account balances, measured on the pre-August-2016 assessment baseline with current maximums inflation-adjusted.³ No FBAR penalty applies where a violation rests on reasonable cause with the balance properly reported.³

Form 8938 non-filing carries a $10,000 failure-to-file penalty plus up to $50,000 in continued-failure exposure after Internal Revenue Service notice, alongside a 40 percent understatement penalty on tax attributable to non-disclosed assets; criminal penalties may also apply.²³ No Form 8938 penalty applies where the failure reflects reasonable cause without willful neglect, assessed case by case.²

A late FBAR remains a violation. Where the Internal Revenue Service has not contacted the filer and no investigation is open, its instruction is to submit late FBARs as soon as possible to keep potential penalties to a minimum.⁴

Eligible non-willful filers can use the Streamlined Foreign Offshore Procedures, covering three years of returns plus six years of FBARs with a Form 14653 certification, to resolve past failures without FBAR penalties absent later fraud or willfulness findings.⁷

Good to know

A small Japan balance can still trigger FBAR

Ordinary checking plus savings balances can jointly cross $10,000 at a mid-year peak even where year-end balances look low.⁴³ Payday, a bonus deposit, or a temporary transfer can create the triggering moment. The test runs on aggregate maximum at any time, not on year-end value.⁴³

Filing Form 8938 never replaces FBAR

The same Japan accounts can sit on both forms where both thresholds are met.²³ The filings go to different recipients under different definitions, so completing the Internal Revenue Service attachment does not notify FinCEN.²³ Run both checks each year rather than assuming the higher-threshold form is the only one that matters.

Keep records for five years from the FBAR due date

Retain the account identity, bank name and address, account type, and maximum-value evidence for five years from the due date.⁴ Bank statements or a filed-FBAR copy carrying the required fields are sufficient; the law does not mandate a specific document format.⁴ An officer or employee reporting only signature authority over an employer's account does not personally keep these records, since the employer holds them.⁴
