What is the Medical Expense Deduction?

A scheme where medical expenses paid in a calendar year that exceed a threshold can be deducted from taxable income, reducing your income tax and resident tax. Employees may receive a refund by filing a tax return if they meet the requirements.

💡 Example: ¥200,000 annual medical bills means ¥100,000 (the amount over ¥100,000) becomes deductible. At a 30% combined tax rate, you get back about ¥30,000.

Are Foreigners Eligible?

Yes. Any Japan tax resident (with Japanese address, living 1+ year) qualifies. Medical expenses of household members (under same economic unit) can be combined into one claim.

Deductible vs Non-Deductible

✅ Deductible

  • Hospital/clinic visits, treatment fees
  • Prescription and OTC drugs (for treatment)
  • Dental treatment (cavities, extraction)
  • Childbirth (prenatal checks, delivery, hospital stay)
  • Fertility treatment
  • Public transport to hospital
  • Massage, acupuncture (for treatment)

❌ Not Deductible

  • Annual health checkups (if no illness found)
  • Vaccinations
  • Cosmetic surgery, teeth whitening
  • Supplements, health foods
  • Regular eyeglasses/contacts
  • Cosmetic orthodontics
  • Amounts reimbursed by insurance
  • Childbirth lump-sum subsidy portion

How to Calculate the Deduction

Deduction = Medical expenses − Insurance reimbursements − ¥100,000 (or 5% of income, whichever is lower, for incomes under ¥2M). Cap is ¥2M.

CASE 1
¥5M income, ¥250K medical expenses
Deduction ¥150K → Refund ~¥45K
CASE 2
Childbirth: ¥600K paid, ¥420K subsidy
Deduction ¥80K → Refund ~¥24K

Self-Medication Tax (OTC Special)

An alternative simpler scheme (choose one of the two). Best for those who buy lots of OTC medicine:

  • Target: designated OTC drugs (switch OTC etc.)
  • Minimum: ¥12,000
  • Maximum: ¥88,000
  • Requirement: Had a health checkup, vaccination, or cancer screening that year

Filing Steps

  1. Collect 1 year of receipts and statements
  2. Prepare the "Medical Expense Deduction Statement"
  3. File via e-Tax (requires My Number Card) or at tax office
  4. Refund arrives in your bank account in 3 weeks–2 months
⚠️ Receipts must be kept for 5 years. Phone photos are OK.

Notes When Leaving Japan

  • Medical expenses from Jan 1 to your departure date are still deductible
  • Before departure, file a "quasi-final return" OR appoint a Tax Manager
  • Refund goes to a Japanese bank account — keep it open
  • You can also retroactively claim for the past 5 years
