② Do You Pay Tax on Overseas Remittances? The Basic Principle
The most important premise is this: "The act of sending money abroad is not itself subject to tax." Whether any tax applies depends on the nature of the money — in other words, whether it constitutes a gift, income, or simply a transfer of your own funds.
Breaking it down into four situations makes it easier to understand.
| Situation | What is being sent | Tax implications |
|---|---|---|
| ① Self → own overseas account | Transferring from your Japanese account to an overseas account in your own name | Not a gift, so in principle not subject to gift tax. However, if the funds originate from unreported income in Japan, a separate income tax issue may arise |
| ② Remittances to family | Sending living expenses or educational fees to parents, children, or siblings in your home country | Living expenses and educational fees in the normal necessary range between persons with a duty to support (legal supporter) are in principle exempt from gift tax (Inheritance Tax Act, Art. 21-3). Large amounts or funds for asset-building purposes require further checking |
| ③ Receiving money from abroad into Japan | Receiving funds in Japan from your own overseas account or from family | A transfer of your own funds is in principle tax-free. If the funds are overseas income, a gift, or an inheritance, further checking is needed |
| ④ Business or income-related transfers | Moving labor income or investment returns earned abroad into a Japanese account | Japanese residents are in principle required to report overseas income as well (determining resident vs. non-resident status is critical) |
③ Report of Overseas Remittances — Transfers over JPY 1 Million Are Known to the Tax Office
What is the Report of Overseas Remittances?
When a single outbound or inbound international transfer exceeds JPY 1 million, financial institutions and registered fund transfer operators (including Wise, PayPal, etc.) are required to submit a Report of Overseas Remittances ("Kokugai Soukin-tou Chousho") to the tax office. This is an information-gathering mechanism to prevent under-reporting of gift tax, inheritance tax, and income tax — it does not mean the transfer itself is taxed.
| Item | Details |
|---|---|
| Who must report | Financial institutions (banks, Japan Post, etc.) and fund transfer operators (Wise, PayPal, Western Union, etc.) |
| Threshold | A single overseas transfer or receipt that exceeds JPY 1 million (no report required for JPY 1 million or under) |
| Information recorded | Name and address of sender and recipient, transfer amount, purpose of transfer, name of receiving financial institution, etc. |
| Purpose | Information gathering to prevent under-reporting of gift tax, inheritance tax, and income tax (not a tax itself) |
| Impact on the sender | No problem if the transfer is properly declared and explained. If there is an under-reporting, it may trigger a tax audit |
④ Remittances to Family and Gift Tax
Living Expenses and Educational Fees Between Legal Supporters Are in Principle Exempt
Under Article 21-3 of Japan's Inheritance Tax Act, when a person with a duty to support (legal supporter — spouse, lineal relatives, siblings, etc.) gives living expenses or educational fees within the normally necessary range, as needed on each occasion, gift tax is in principle not levied.
The conditions for tax exemption are as follows.
- ① The gift is from a person with a duty to support (spouse, lineal relatives, siblings, etc.)
- ② The funds are actually used for living expenses or educational fees
- ③ The amount is within the normally necessary range
- ④ The funds are provided directly as needed, on each occasion (lump-sum transfers require caution)
Comparison: Cases That Are Likely Tax-Exempt vs. Cases That May Be Taxed
| Case | Tax treatment | Key point |
|---|---|---|
| Monthly living expenses (food, rent equivalent) sent to parents as needed | In principle tax-exempt | Meets all three conditions: between legal supporters, living expenses, provided as needed |
| Transfer to pay a child's tuition or study materials directly to the school | In principle tax-exempt | Meets the educational-fee and direct-payment conditions |
| Large lump-sum transfer (e.g., several years' worth sent all at once) | May be subject to gift tax | May not meet the "as needed" condition. Consult a tax accountant individually |
| Recipient puts the received money into savings or investments | May be subject to gift tax | Actual use for living expenses or educational fees is a condition. Asset-building purposes may be taxed |
| Transfer to a relative outside the siblings category (uncle, aunt, etc.) | Requires checking | If outside the scope of legal supporters, a gift tax return may be required |
| Self → own overseas account (same name) | Not subject to gift tax | This is a transfer of your own funds, not a gift. Income tax implications should be checked separately |
Keeping Supporting Documents Is Essential
Especially when remittances exceed JPY 1 million, we strongly recommend keeping bank transfer records, receipts showing how the recipient spent the funds on living costs, and notes on the purpose of the transfer. These will serve as evidence of the legitimate purpose if the tax office makes an inquiry.
⑤ Receiving Money from Abroad into Japan
Transferring Funds from Your Own Overseas Account to Your Japanese Account
Transferring funds from an overseas account in your own name to a Japanese account in your own name is, in principle, not subject to gift tax. This is a movement of the same person's assets and does not constitute a gift.
However, the following points require attention.
- If the transferred funds originate from income that is subject to Japanese taxation but has not been declared, an income tax issue may arise
- Income earned abroad or investment gains accumulated in overseas accounts may in principle be subject to reporting requirements if you are a Japanese resident
Receiving Funds from Family Abroad into Your Japanese Account
When receiving money from family overseas (parents, etc.) into your Japanese account, you need to confirm the following.
| Nature of the funds received | Tax treatment (in principle) |
|---|---|
| Living expenses from parents (support for daily life in Japan) | As normally necessary living expenses between legal supporters, may in principle be exempt from gift tax |
| Large sum received from parents (for asset formation, home purchase, etc.) | May become subject to gift tax. Check whether a declaration is required |
| Receiving labor income or investment returns earned abroad | Japanese residents are in principle required to report this (income tax) |
| Receiving inherited assets from abroad | May become subject to inheritance tax in some cases. Strongly recommended to consult a specialist |
⑥ Resident vs. Non-Resident and Tax Scope
In Japan's tax system, the scope of taxation differs significantly depending on whether a person is a "resident" or "non-resident." For foreigners, the determination varies based on visa status, length of stay, and other factors, so we strongly recommend confirming your specific situation with the NTA or a tax accountant.
| Category | Overview | Tax scope (in principle) |
|---|---|---|
| Resident (unlimited tax liability) | A person who has a domicile in Japan or has had a place of residence in Japan for one year or more | All domestic and overseas income, gifts, and inheritances may be subject to tax |
| Non-resident (limited tax liability) | Anyone other than a resident (e.g., domicile is abroad) | In principle, only domestic property and Japan-source income are subject to tax |

⑦ Remittance Methods and How to Keep Records as Proof
Your Transfer Records Are the Foundation of Your Proof
The most important thing for proving the purpose of your remittances is to keep accurate records of every transfer. Bank transfer statements serve this purpose for wire transfers; with FinTech services like Wise, the in-app transfer history and statements can be used directly as evidence.
Keep the following types of documents and records.
- Bank transfer statements or remittance receipts (showing date, amount, recipient name, and purpose)
- Receipts or photos showing how the recipient used the funds for living costs (optional but powerful evidence)
- If claiming the overseas dependent deduction, remittance-related documents (transfer request forms, etc.) must be attached to the tax return
Using Wise and Similar Services Automatically Keeps Your Records
When you use a fund transfer operator such as Wise, the date, amount, recipient, currency, and fee are all automatically recorded in the app. You can also download a PDF statement, making it easy to use the records both to respond to a Report of Overseas Remittances inquiry and as proof of remittance for the dependent deduction.
Are you losing money on transfer fees and exchange rates without realizing it? Wise (multi-currency transfers) has a clear fee structure and can sometimes send at near the real exchange rate.
※Fees, exchange rates, and supported countries are subject to change. Please check the official website for the latest information. Availability may depend on your visa status and identity verification result. Wise is a service provided by Wise Payments Limited.
⑧ When You Receive an Inquiry Letter ("Otazune") from the Tax Office
Based on a Report of Overseas Remittances or the contents of a tax return, the tax office may send you an inquiry letter ("otazune") — a document requesting information or confirmation. Even if you receive one, there is no need to panic.
Basic Steps for Responding
| Step | What to do |
|---|---|
| ① Stay calm and read it carefully | An "otazune" is not the start of a formal tax audit — it is a request for information. Responding within the deadline is generally all that is needed |
| ② Gather the facts and supporting documents | Collect explanatory materials based on the facts: transfer statements, purpose of the transfer, the recipient's circumstances, etc. |
| ③ Answer honestly | Explain the facts straightforwardly. If the transfer was "living expenses sent to parents in your home country," state that and attach supporting documents |
| ④ Consult a specialist or the tax office for anything unclear | If you are unsure about any part of your response, make use of free consultations with a tax accountant or the tax office (available during the final tax return season, etc.) |
⑨ Remittances and Tax When Returning to Your Home Country
The period just before returning to your home country or departing Japan involves several important points to keep in mind.
Final Remittance Before Departure
It is common to send a lump sum of your remaining funds to your home country just before you leave. Transferring to an account in your own name is in principle not subject to gift tax, but keep in mind that transfers over JPY 1 million will trigger a Report of Overseas Remittances, so be sure to keep records that allow you to explain the purpose and origin of the funds.
Watch Out for Outstanding Residence Tax (Jumin-zei)
Residence tax is levied in the current year based on the previous year's income, which means that even if you return home mid-year, residence tax for the following year may still arise. Before resigning and departing, check your remaining residence tax balance and make sure you do not leave Japan with unpaid amounts.
Appointing a Tax Agent (Nozei Kanrinin)
If your final tax return deadline (February–March of the following year) will fall after you have already returned home, you must appoint a "tax agent (nozei kanrinin)" and notify the tax office before departing Japan. A tax agent can be anyone living in Japan — a friend, a tax accountant, etc.
