Medical expenses deductions

Medical expenses deductions are part of a system whereby if the amount of medical care costs paid in one year,including those of family members, exceeds a certain standard, you can file a final tax return with the tax office to have the excess amount of medical care costs deducted from your taxable income and have some of your taxes refunded.

Calculation Method

Deductions for medical expenses are calculated in this manner.

Calculation Method

Examples of cases in which medical expenses can be deducted

【 Medical expenses 】 ¥500,000
【 Amount supplemented by health insurance 】 ¥350,000
【 Amount in hand 】 ¥4 million (per year)
→ ¥4 million x 5% =
¥200,000 > ¥100,000

¥500,000 - ¥350,000 - ¥100,000 = ¥50,000 ( Amount of deduction for medical expenses )

¥50,000 - 20% = ¥10,000 ( Amount to be refunded )
