💡 Key Points
  • The Dependent Deduction is a scheme that allows a set amount to be deducted from taxable income when you financially support a relative, and parents, siblings, or children living overseas may also qualify as an 'overseas dependent'.
  • Under the 2023 (Reiwa 5) reform, overseas dependents aged 30 to under 70 no longer qualify for the deduction unless they meet one of three conditions: being a student, having a disability, or having received 380,000 yen or more in remittances during the year.
  • Eligible relatives must be blood relatives within the 6th degree or relatives by marriage within the 3rd degree who share living expenses with you, and must meet conditions such as annual income of 480,000 yen or less and being aged 16 or older.
  • Applications require documents proving the family relationship, and (for those aged 30–69) documents proving remittances; documents in a foreign language must be accompanied by a Japanese translation.

What is the Overseas Dependent Deduction?

Foreign workers in Japan who financially support family members abroad (parents, siblings in China, Vietnam, etc.) may claim a dependent deduction — reducing income tax and resident tax. Depending on income and number of dependents, annual tax savings can reach ¥100,000–¥200,000 or more.

💡 If you send ¥380,000 or more per year (about ¥32,000/month) to support a parent aged 30–69, you likely meet the main requirement introduced in the 2023 reform.

2023 Tax Reform — Key Changes

From January 2023, non-resident dependents aged 30–69 must meet at least one of the following three conditions:

⚠️ Dependents aged 30–69 must meet ①, ②, or ③

  • Student enrolled at a foreign educational institution
  • Person with a disability as defined by income tax law
  • ③ Received ¥380,000 or more in living/education expenses from the Japan taxpayer that year

For typical parents aged 50s–60s (not students, not disabled) → you must prove annual remittances of ≥¥380,000.

Who qualifies as an overseas dependent?

To be treated as a “dependent relative” for the dependent deduction, the person must meet all of the following conditions.

✅ Qualifies

  • Blood relatives within the sixth degree of kinship (parents, grandparents, siblings, children, grandchildren, etc.)
  • Relatives by marriage within the third degree (your spouse’s parents, etc.)
  • Someone who shares a common household budget with you (you send money for living expenses)
  • Someone whose annual income is 480,000 yen or less (employment income of 1,030,000 yen or less)
  • Someone aged 16 or older (under 16 counts as a young dependent, for which no deduction applies)
  • Someone who meets the 2023 reform requirement (for ages 30–69, one of the three conditions ①②③)

❌ Does not qualify

  • Children under 16 (the deduction for young dependents was abolished)
  • Annual income over 480,000 yen (relatives who earn income locally)
  • Your spouse (covered by the spousal deduction / special spousal deduction instead)
  • Anyone aged 30–69 who meets none of study abroad, disability, or 380,000 yen in remittances
  • The parents of a common-law or de facto partner
📌 What “sharing a common household budget” means: for an overseas dependent, even if you do not live together, you are recognized as sharing a common household budget if there is a record of you regularly sending money for living or education expenses. Remittance records serve as the evidence.

Deduction Amounts

CategoryAgeIncome TaxResident Tax
General dependent16–18, 23–69¥380,000¥330,000
Specified dependent19–22¥630,000¥450,000
Elderly dependent70+¥580,000¥380,000

Tax Savings Examples

CASE 1
¥5M income, parent 70+ (elderly dependent)
Income tax (¥580K × 20%) + Resident tax (¥380K × 10%) = ~¥154,000 saved/year
CASE 2
¥4M income, parent 50s (remitting ≥¥380K/year)
Income tax (¥380K × 20%) + Resident tax (¥330K × 10%) = ~¥109,000 saved/year

Required Documents (2 types)

① Proof of Relationship

  • Official government document showing family relationship (family register, birth certificate, marriage certificate)
  • Must include a Japanese translation (self-translation is permitted — include your name and address as translator)

② Proof of Remittance (required for dependents aged 30–69)

  • Bank international transfer records (total ≥¥380,000/year)
  • Wise transaction history PDF (downloadable from your account)
  • SBI Remit or GMO Remit transfer history
  • Recipient must be the dependent or their household
✅ If you use Wise to send ¥32,000–¥40,000/month, just download the transaction history PDF — it serves as your remittance proof. → Wise Guide

How to File

Employees (year-end adjustment): Fill in the "Non-resident dependent" section on the Year-End Tax Adjustment form (扶養控除等申告書) and submit with documents to your HR/payroll dept. by October–November.

Self-employed or missed year-end adjustment: File a tax return (確定申告) between February 16 and March 15, attaching both document types.

✅ You can retroactively claim for up to 5 years (e.g., year 2021 can be filed until December 31, 2026).

Remittance and dependent deduction

Since the 2023 reform, sending 380,000 yen or more per year has been a condition of the deduction for overseas dependents aged 30–69. Below is a summary of how to send the money and keep records.

  • Ideally send to an account in the dependent’s own name: a transfer into the dependent’s own account is the easiest to prove
  • 380,000 yen or more in annual total: 32,000 yen per month × 12 months = 384,000 yen clears the requirement
  • The currency does not matter: even if the money is received in a local currency such as Chinese yuan or Vietnamese dong, the requirement is met as long as the amount sent is equivalent to 380,000 yen or more
  • Wise and SBI Remit records can be used: these services let you export your transaction history as a PDF, so it can be used as proof of remittance
  • Cash handed over in person is hard to prove: cash carried on a visit home leaves no supporting document and is unlikely to be accepted
💡 Remittances to China or Vietnam work together with this deduction: if you send 30,000–40,000 yen a month through Wise, you are in many cases already meeting the annual 380,000 yen requirement. Simply downloading and keeping your Wise transaction history gives you a document you can use for your filing each year. → Wise remittance guide / Japan → China remittance comparison

FAQ

My parent is 65 and I send ¥300,000/year. Can I claim the deduction?
Under the 2023 reform, dependents aged 30–69 need ≥¥380,000/year unless they are students or disabled. ¥300,000 is not enough — increase remittances to ≥¥380,000 to qualify.
My parent just turned 70 — can I start claiming now?
Yes. From the year they turn 70, they qualify as an "elderly dependent" (¥580,000 deduction). The 2023 reform's ¥380,000 remittance requirement does NOT apply to dependents aged 70+.
My company refuses to process overseas dependents. What can I do?
If your company won't process it through year-end adjustment, you can file a tax return (還付申告) yourself the following year. Prepare your documents and file via e-Tax or at the tax office.
Can I claim both the dependent deduction and the medical expense deduction?
Yes — they are separate schemes and can be combined in the same tax return for additional savings.
PR Already sending money home to support your family?

Claiming this deduction relies on the money you already send home. Sending to the Philippines, Vietnam, Nepal or elsewhere? Compare low-cost ways to transfer — no credit check needed. Wise uses the mid-market exchange rate with clear, upfront fees, and its downloadable transaction history also works as your proof of remittance; you can verify with your residence card and finish online.

SBI Remit is also worth comparing for direct deposits to bank accounts in China, Vietnam or the Philippines. For a full comparison of Wise, SBI Remit and bank wires, see our international remittance comparison. We introduce licensed providers and may earn a commission (PR); we are not a money-transfer operator. In Japan, Wise is provided by Wise Payments Japan K.K., a registered Funds Transfer Service Provider (Kanto Local Finance Bureau No. 00040). Fees and exchange rates change — check the official site. Sending money abroad does not affect your residence status.
