Rental income tax for landlords

Rent, fees, deposits, expenses, depreciation, interest, vacancy, and blue returns.

Direct answers

Rental income is rent plus nonrefundable deposits and renewal fees, minus necessary expenses like fixed-asset tax, insurance, depreciation, repairs, and the rental portion of loan interest — loan principal is never deductible, and a blue return can add a special deduction.

Key points

  • Income includes rent, nonrefundable deposits, and renewal fees.
  • Deductible: fixed-asset tax, insurance, depreciation, repairs, interest.
  • Loan principal is never deductible; interest may be.
  • Example: ¥2.4M income − ¥1.5M expenses = ¥900,000 rental income.

What counts as income

Rental income includes rents, nonrefundable deposits (e.g., key money), renewal fees, and tenant reimbursements. A refundable security deposit is not income until it becomes nonrefundable. Necessary expenses commonly include fixed-asset tax, property insurance, depreciation, and repairs. As a worked example: ¥2.4M of rent and nonrefundable fees minus ¥1.5M of expenses is ¥900,000 of rental income.

Interest, principal, and blue returns

Qualifying loan interest is deductible but loan principal repayment is not — a frequent mistake. Capital improvements are depreciated rather than expensed. If your rental rises to the level of a business, a blue return can add a special deduction and family-employee salaries. Keep the purchase contract, land/building allocation, loan statements, and a depreciation schedule.

Who this is for

  • Residential and commercial landlords
  • New property investors

What this is not

  • Property sales (separate capital gain)
Important cautions
  • Loan principal is not deductible — only qualifying interest is.

Frequently asked questions

Do I need to file a tax return in Japan?

Many employees do not, because tax is settled by year-end adjustment (年末調整). You generally must file (確定申告) if you have side income over ¥200,000, two or more employers, self-employment income, sizeable investment or crypto gains, or you want to claim deductions like large medical costs or a first-year mortgage credit. Filing season is Feb 16 – Mar 15 via e-Tax. When unsure, check the NTA guidance or ask a 税理士.
