Form 8938 for Americans in Japan

Country-specific records and U.S. filing questions for Form 8938 when an American lives, works, owns assets, or has transactions connected to Japan. Identify the records needed before agreeing on preparation scope.

Start with the facts

Country, state, residence, ownership, work location, and tax year facts come before a form conclusion.

Written scope before preparation

Describe your filing needs first. Any paid review, preparation scope, and price are agreed before work begins.

Why specified foreign financial asset reporting requires a Japan records review

Form 8938 reports specified foreign financial assets when the applicable filing-status and residence thresholds are met, with definitions that differ from FBAR. Japan taxes residents on worldwide income. National progressive rates: 5% to 45%, plus flat 10% local inhabitant tax (prefectural + municipal), plus 2.1% reconstruction surtax on national tax. Preserve local registration, assessment, payment, withholding, and currency records by tax year rather than copying a local total into a U.S. form. Foreign accounts, securities, interests in entities, contracts, and other specified assets must be inventoried and tested under the tax-year thresholds and exceptions.

Residence, work, and source facts in Japan

A Japanese residence card (zairyu card), registration at city hall (juminhyo), and a My Number (individual number) strongly support bona fide residence. Japanese tax filings (kakutei shinkoku) provide additional evidence. Build the residence file from the permit, home, family, days, work, and local filing records together. For presence, residence, and work facts in Japan: Japan is geographically distant from the US, making the 330-day test easier to meet. However, business trips to the US and home visits must still be tracked. Japan's strict immigration system means your visa status is well documented. Keep payer, contract, service-location, payroll, and entity records separate. Keep the residence timeline, travel calendar, work location, and relevant local returns for the tax year being reviewed.

The Japan accounts, products, and entities to inventory

Examples you may encounter include MUFG Bank (Mitsubishi UFJ), Sumitomo Mitsui Banking Corporation (SMBC), Mizuho Bank. Identify the legal owner, account or product type, currency, and documents available. A local product name alone does not establish its U.S. tax classification.

Documents to request before preparing Form 8938

Gather the following records, along with relevant Japan tax returns, assessments, and payment evidence. Keep original-currency amounts and the exchange-rate method used.

  • maximum and year-end account values
  • custodian statements and account numbers
  • ownership and beneficiary documents
  • foreign entity or trust records
  • FBAR comparison and exchange-rate support

Country-specific questions that can change the U.S. result

Use these questions to identify missing facts in the Japan file:

  • Is the asset held through a bank, broker, pension, trust, or entity?
  • Does the country statement show the maximum value?
  • Is the asset reportable on Form 8938, FBAR, both, or neither?

Common mistakes for Americans filing from Japan

Check for these form-specific issues:

  • treating Form 8938 and FBAR as interchangeable
  • omitting non-bank foreign financial assets
  • using the filing threshold without considering filing status and residence

Facts to review for Form 8938 in Japan

A U.S. person in Japan needs country-specific FATCA and FBAR account classification to test Form 8938 thresholds and exceptions.

  • Japan signed a Model 2 IGA with the US in 2013, meaning Japanese banks report directly to the IRS (not through Japanese tax authorities). Major Japanese banks comply with FATCA but may require additional documentation from US citizens.
  • A Japanese cash-value insurance or annuity policy may be a foreign financial account under FinCEN's current definition. Test foreign location, U.S.-person status, financial interest or signature authority, aggregate maximum value, filing year, and applicable exceptions; pension and insurance products require product-specific review.
  • Local currency: JPY.

Frequently asked questions

Does living in Japan automatically require Form 8938?

No. The filing question depends on the form's trigger, the taxpayer's status, the legal owner, the tax year, and the records. Living in Japan identifies the local documents to gather; it does not replace the U.S. instructions or a fact-specific review.

Which Japan records should I gather first?

Start with residence and travel records, local tax identification and returns, bank or investment statements, income and withholding records, the legal documents for any entity or plan, and the original-currency conversion support. Then add the form-specific records listed on this page.

Can a local tax return replace the U.S. Form 8938 analysis?

No. A local return can provide evidence about income, tax paid, residence, or ownership, but U.S. forms use their own definitions and tax-year instructions. Reconcile the local return with the U.S. filing rather than copying its categories.
