CRS Reporting in Japan for Non-US Foreign Tax Residents

CRS Japan reporting means the bank or broker where you hold an account sends your account details to your home tax authority each year.¹ The trigger is a single self-certification form at account opening, and the practical consequence is visibility rather than an automatic tax bill.²

Confirm current details with official sources

Procedures, fees, and requirements can change. Confirm current details at the National Tax Agency site. This article is general information, not legal, tax, or immigration advice; for your specific case, consult a licensed tax accountant (税理士, zeirishi) for the Japan side or a qualified tax adviser in your home jurisdiction for the home-country side.

Overview

The 共通報告基準 (kyōtsū hōkoku kijun, "Common Reporting Standard") is the OECD-developed framework under which each participating jurisdiction collects financial-account information about non-residents from its own institutions and exchanges it with other jurisdictions automatically every year.¹³ Japan is one of more than 100 jurisdictions implementing this exchange (as of 2025-06; confirm current participation with the National Tax Agency or the OECD), and Japan began exchanging information in 2018 (as of 2025-06).¹

The public signatory roster for the multilateral competent-authority agreement evidences that breadth of participation, and Japan appears on it (as of 2025-03-13).⁴ The standard itself was amended in 2022 to expand reporting requirements, and Japan's implementing amendments took effect on January 1, 2026 (as of 2025-06).¹

This article covers the non-US foreign-tax-resident track only. US-person FATCA and FBAR mechanics belong to separate articles and are excluded here.¹

How CRS Exchange Works Between Japan and Other Jurisdictions

Japanese 報告金融機関等 (hōkoku kin'yū kikan-tō, "reporting financial institutions") report to the National Tax Agency, which then exchanges the data with the account holder's home tax authority under tax-treaty information-exchange provisions.¹ The flow runs in the same direction every year, as the map below shows.¹

The Japan-side procedure is uniform nationwide under national law. Which foreign jurisdiction receives the data depends on your own tax-residence status, and home-country tax consequences vary by home jurisdiction.²

Which institutions and accounts are covered

Reporting institutions include depository institutions such as banks and funds transfer service providers, specified insurance companies such as life insurance companies, custodial institutions such as securities companies, and investment entities such as trusts.¹ The system dates to the 2015 tax-reform amendments to the Act on Special Provisions, in force from January 1, 2017, with institutions reporting each year since 2018.¹⁵⁶

Covered accounts include ordinary savings accounts and specified electronic money product accounts, cash value insurance and annuity contracts, securities-type custodial accounts, and trust beneficiary interests.¹ Amended-scope items such as specified electronic money products fall inside the system from January 1, 2026 (as of 2025-06; confirm current scope with the National Tax Agency).¹

What information travels each year

Each annual filing identifies the holder by name, address, 居住地国 (kyojūchi-koku, "jurisdiction of residence"), and foreign taxpayer identification number, plus whether a qualifying self-certification was provided.¹ It also states the account type, the new-versus-preexisting classification, the balance or value, and the year's totals of interest, dividends, and similar receipts.¹

Reportability is measured as of December 31 each year, and institutions file by April 30 of the following year.¹ The timetable below summarizes the yearly cycle.¹

Step	Timing	As of	Notes
Snapshot date	December 31	2025-061	Reportable contracts held on this date set the filing population
Institution filing	By April 30 of the following year	2025-061	Filed with the district director over the institution's head office
Exchange outward	After filing, under tax treaties	2025-061	NTA provides the data to the foreign tax administration

The exchange is reciprocal. While Japan sends data about foreign residents' Japanese accounts outward, it also receives data about Japanese residents' accounts held abroad.²

Self-Certification at Account Opening

Anyone opening a financial account with a reporting institution in Japan on or after January 1, 2017 submits a self-certification for new accounts at the counter, stating name, address, jurisdiction of residence, foreign taxpayer identification number, and related items.¹²⁵ Tax residence here means the jurisdiction where you pay tax equivalent to Japan's income or corporation tax.²⁵ The National Tax Agency keeps the current leaflets, including the from-2026 set, on its International Taxation page.⁷

The decision below sketches which line your situation falls on.²⁸

What the bank asks and what to write

Customers whose jurisdiction of residence is Japan still write "Japan" on the form. In that case the Japanese Individual Number (My Number) is not required.²⁸⁵

When the jurisdiction of residence is foreign, the foreign taxpayer identification number is legally required on the form.²⁸ Holders whose tax residence is outside Japan spell their name and residence address in the Latin alphabet.⁸ The institution checks the form against the other documents shown at opening.²

List every residence jurisdiction on the same form

Treaty tie-breaker rules do not shrink the form to one line. When Japan plus a foreign jurisdiction both apply, both go on the self-certification.²

Preexisting accounts and changes in circumstances

Accounts opened on or before December 31, 2016 never had an opening-day form. Each institution instead identified their holders' residence jurisdictions from its own records, generally by December 31, 2018.¹ Even so, holders of older accounts can still be asked to submit a self-certification for confirmation.²⁵

Accounts opened on or before December 31, 2025 that never went through either procedure fall under a renewed institution-side identification duty, generally completable by December 31, 2027.¹ When your jurisdiction of tax residence changes after any filing, submit a change notification; SBI Shinsei Bank states a three-month-from-change window for its customers.⁸⁵

An address change that does not change the residence jurisdiction needs no change notification.⁶ Individual holders who never filed may instead be asked for a foreign taxpayer identification number notice as a substitute.⁶

What This Means in Practice for Non-US Expats

For typical UK, EU, Australian, and Canadian residents in Japan, the practical effect is straightforward. Your home tax authority receives information about your Japanese accounts every year once you are identified as its tax resident, even if you owe no home-country tax on them.¹²

Visibility is not the same as a tax bill

Reporting activates whenever the declared residence is a specified foreign (reportable) jurisdiction.¹² The filing itself assesses no tax. Whether your home jurisdiction charges anything on the reported balances or income depends on its own residence-based tax rules, which differ by country and sit outside this article's scope.¹²

Foreign tax-residence status is determined under the foreign jurisdiction's own laws, by criteria such as address or residence period, management location, or nationality.² The OECD portal publishes jurisdiction-by-jurisdiction residence rules for checking your own position.²

False statements on the form carry statutory penalties

SMBC Trust Bank notes penalties of a fine of up to 500,000 yen or up to 6 months in prison for false self-certification statements or non-submission. Refusal at opening can also block the application itself.⁶

Keeping records consistent across jurisdictions

The fields that must stay aligned are name, address, jurisdiction of residence, and foreign taxpayer identification number.²⁵ After a move or a taxpayer number change, file the update so the bank, the National Tax Agency, and the receiving authority all hold the same data.⁸⁵⁶

When your address and your declared jurisdiction of residence do not correspond, the form requires a written reason explaining the gap.²⁸ Prepare that explanation before you visit the counter, since the bank verifies the form against your identity documents.² Jurisdiction-specific taxpayer-number guidance is published on the OECD portal and the National Tax Agency's CRS pages.²

Good to know

The tax-residence question can block your application if skipped

New-account applicants must submit the self-certification at opening, and at least one major bank states plainly that it does not accept applications without it.⁶ Treat the form as part of the account-opening checklist, alongside identity documents, rather than as follow-up paperwork.²⁵

Dual residents list Japan and the foreign jurisdiction together

A reader living in Japan who remains tax-resident elsewhere writes both jurisdictions on the same form.² NTA guidance requires every applicable jurisdiction to be indicated when more than one applies.² Confirm any tie-breaker reading with a tax accountant instead of dropping a line on your own initiative.²

Address-residence mismatches need a reason in writing

Cross-border lives produce gaps naturally, such as a Japanese address with a home-country tax residence during a transition year.⁸ The form anticipates this and asks for the specific reason.²⁸ A one-sentence factual explanation attached at filing avoids a returned form and a second branch visit.²

The cycle runs on year-end snapshots and spring filings

Institutions measure the filing population as of December 31 and file by April 30 of the following year, after which the National Tax Agency exchanges the data under treaties.¹ A residence change late in the year therefore belongs on an updated filing promptly, not at the next account opening.⁸⁵
