Sending Money Home? How Foreigners Claim Overseas Dependent Tax Deductions (Fuyo Kojo) in Japan

"I'd been sending money home to my parents in the Philippines every month for two years without knowing I could claim them as overseas dependents on my Japanese taxes. A coworker mentioned it during a lunch break. I went back and calculated what I'd missed — roughly ¥180,000 in unclaimed deductions over two years. I filed a retroactive claim at the tax office and got most of it refunded. The only problem was I'd been sending one bulk transfer to my father's account to cover both parents. The tax office rejected half the claim because the transfers weren't in each parent's individual name."

If you support family members living outside Japan by sending regular financial remittances, Japanese tax law allows you to claim them as overseas dependents (国外扶養親族). Claiming the Dependent Exemption (扶養控除 - Fuyo Kojo) reduces both your annual Income Tax (所得税) and your Year 2 Resident Tax (住民税), saving typical foreign workers between ¥50,000 and ¥200,000 every single year.

However, Japanese tax authorities have strictly updated proof requirements for non-resident dependents. To claim this legal tax reduction, foreign workers must submit specific official relationship documents and strict banking remittance records. Here is your step-by-step practical guide to claiming foreign dependents during Year-End Tax Adjustment (年末調整) or Final Tax Return (確定申告).

💡 Quick Expat Summary

  • Substantial Tax Savings: Each eligible overseas dependent reduces your taxable base, directly lowering your monthly income tax and next year's municipal residence tax bill.
  • Individual Remittance Rule: You must send money to each dependent separately in their own name. Sending a bulk payment to one family member to distribute locally is strictly rejected.
  • ¥380,000 Rule for Young Adults (Ages 19–22): Dependents aged 19 to 22 living abroad must receive at least ¥380,000 annually in proven remittances to qualify for the exemption.

Eligibility & Strict Rules for Overseas Dependents

Before gathering paperwork, ensure your overseas relatives meet the official NTA (National Tax Agency) guidelines:

  • Eligible Relatives: Relatives within the 6th degree by blood or 3rd degree by marriage (e.g., parents, spouse, children, siblings, grandparents).
  • Age Category Rules:
    • Ages under 16 & 70+: Fully eligible with valid relationship and remittance certificates.
    • Ages 30 to 69: Eligible only if they are full-time students abroad, disabled, or receiving at least ¥380,000/year from you for living expenses.
  • Hand-Carried Cash Invalid: Cash handed over in person during home visits or sent via informal peer-to-peer couriers is 100% disqualified. Money must pass through licensed financial institutions.

⚠️ Crucial Warning: Avoid Joint Account & Single Transfer Traps

If you wish to claim both your mother and father, you cannot send ¥600,000 to your father's account alone and claim both parents. The tax office requires separate remittance certificates (送金関係書類) bearing each parent's individual name. Always make individual transfers to each relative's personal bank account.

Required Documents for Foreign Dependent Deductions

You must prepare two sets of official documents (with Japanese translations attached):

1. Family Relationship Documents (親族関係書類)

Official government certificates from your home country proving your familial relationship (e.g., birth certificates, marriage certificates, or official family registry documents). Original copies or verified transcripts are accepted.

2. Remittance Documents (送金関係書類)

Official statements from licensed money transfer providers (e.g., Wise, Revolut, SBI Remit, or traditional bank wire receipts) covering the specific tax year. The document must explicitly show:

  • Your name as the sender.
  • The exact dependent's name as the recipient.
  • The exact transaction dates and converted amounts in JPY or foreign currency.

Tax Filing Methods Compared: Company vs. Tax Office

Filing Method Submission Period Submission Place Best For
Year-End Adjustment (Nenmatsu Chousei) November – December Your employer's HR / Accounting desk Full-time company employees looking for immediate December tax refunds.
Final Tax Return (Kakutei Shinkoku) Feb 16 – March 15 Local Tax Office (Zeimushu) or e-Tax Those who missed HR deadlines or whose companies refuse dependent processing.

Useful Japanese Phrases for Dependent Tax Claims

📌 Key Japanese Phrases for HR & Tax Office

  • "I want to claim overseas dependent deduction for my parents."
    国外扶養親族の控除を申請したいです。(Kokugai fuyo shinzoku no kojo o shinsei shitai desu.)
  • "Here are my remittance certificates and translated relationship documents."
    送金関係書類と翻訳付きの親族関係書類です。(Soukin kankei shorui to honyaku-tsuki no shinzoku kankei shorui desu.)
  • "Can I claim this deduction retroactively for previous years?"
    過去の分を遡って還付申告できますか？(Kako no bun o sakanobotte kampu shinkoku dekimasu ka?)

Summary: Keep Your Remittance Receipts Every Year

Claiming overseas dependents is one of the most substantial legal tax reliefs available to foreign workers in Japan. By switching from bulk transfers to individual monthly or quarterly remittances via recognized apps like Wise or SBI Remit, downloading annual statements, and submitting them during Year-End Adjustment, you can keep more of your hard-earned income legally!

Your Phone Will Scream in Japanese During a Disaster — Here's How Foreigners Stay Safe in Japan (2026)

Your Phone Will Scream in Japanese During a Disaster — Here's How Foreigners Stay Safe in Japan (2026) "My first earthquake in Tokyo hit at 2am. The alarm screamed, my phone lit up in Japanese, and I had absolutely no idea what to do. I just stood there frozen while my Japanese neighbors calmly got under their tables. That night I realized I was completely unprepared." Updated September 2026  |  Written by Luna H It happens without warning. A piercing alarm blasts from every smartphone in the room. Your screen lights up with kanji you can't read. People around you drop to the floor and cover their heads. You freeze — because nobody told you what to do. Japan averages 1,500 detectable earthquakes per year . Most are small. But living here without a disaster plan isn't just uncomfortable — it's genuinely dangerous. And for foreigners, the biggest risk isn't the earthquake itself. It's not knowing what the alerts mean, where to go, or what to have ...

Health Insurance Isn’t Enough in Japan? Foreigner’s Guide to Private Medical Insurance (Iryo Hoken) & Pre-Existing Condition Hacks "I spent four days in a Tokyo hospital after an emergency appendectomy. My public health insurance covered 70% of the treatment — but nobody warned me about the private room charge of ¥18,000 per day, the daily meal fees, or the advanced medication costs that weren't covered at all. My final bill was ¥340,000 out of pocket. A colleague visited me in the hospital and mentioned she paid ¥800 a month for private insurance that would have covered almost all of it. I signed up the week I was discharged." Updated September 2026  |  Written by Luna H Many foreign residents in Japan believe that enrolling in Japan’s mandatory National Health Insurance (NHI) or Employee Health Insurance provides complete financial protection. However, while public insurance covers 70% of standard medical fees, you are still responsible for the remaining 30%. In cas...
